- 00:09So good afternoon everyone.
- 00:11So welcome to sleep seminar.
- 00:13So it's my first. I'd like to start
- 00:15with a couple of reminders that that
- 00:18these seminar sessions are available
- 00:20for CME credit and that in order to
- 00:23receive credit you do need to text
- 00:25the unique ID to the Yale cloud.
- 00:27See any account that information
- 00:29will show up in the chat.
- 00:31If you do have questions.
- 00:32During the talk,
- 00:33please use the chat feature so that way
- 00:36we can get to those questions at the end.
- 00:39Otherwise at the end we can ask you to
- 00:41unmute yourselves if you prefer to ask
- 00:43your own questions and then finally do,
- 00:45please keep your microphone
- 00:46muted throughout the talk.
- 00:48So now it is my great pleasure to
- 00:51introduce today's speaker Dr Siren,
- 00:53Pastor Athy.
- 00:54Dr.
- 00:54Parthasarathy is professor of
- 00:56medicine at University of Arizona,
- 00:58chief of the Division of Pulmonary
- 01:00Allergy Critical Care and Sleep Medicine.
- 01:03Director of the University of
- 01:04Arizona Health Sciences Center
- 01:06for Sleep and Circadian Sciences.
- 01:08Medical director for the Center of
- 01:10Sleep Disorders Banner University

- 01:18Madras Medical College in India
- 01:20and following anesthesia training.
- 01:21Did his postdoctoral training,
- 01:23including a pulmonary critical care
- 01:26fellowship in Chicago at Loyola.
- 01:28He was director of the Sleep Disorder
- 01:30Center at Loyola before moving to

- 01:45his CV includes over 100 come somewhat
- 01:48diverse and peer reviewed publications
- 01:50with many additional book chapters,
- 01:52abstracts and invited presentations.
- 01:54He has been a strong force in
- 01:58education in both ATS and ASM.
- 02:00His current research interests include
- 02:02sleep intervention during acute lung injury,
- 02:05positive airway pressure therapy for sleep,
- 02:06disordered breathing,
- 02:07and heart failure.
- 02:08Adherence to CPAP therapy in
- 02:10patients with sleep,
- 02:11disordered breathing and
- 02:12sleep deprivation in urine.
- 02:14Models we are so pleased to have
- 02:16doctor Pothys Rocky joined us
- 02:19today to discuss CPAP adherence,
- 02:21treatment, treatment,
- 02:22adherence in patients with sleep apnea,
- 02:24welcome doctor practice,
- 02:25wealthy.
- 02:26Thank you, thanks Janet.
- 02:28Thanks for the kind of invitation and
- 02:31thanks to all I see a lot of familiar
- 02:33faces and hello to everyone at Yale and
- 02:36it's an honor to be amongst you and.
- 02:40I will be talking about
- 02:41see Pepper Durance today.
- 02:42I understand you have a hard stop.
- 02:44So uh, I will try to stay within
- 02:48my time limit so that there's
- 02:50time for some questions.
- 02:51So I do have a disclosure.
- 02:55I am a consultant for Jazz Pharmaceuticals
- 02:59and I believe this is information for
- 03:02your folks who are interested in CME.
- 03:07Uhm, I you know these are some
- 03:10of my funding sources, UM?
- 03:12I wanted to start off with
- 03:16this philosophical slide.
- 03:17Uhm, uhm, and this is Everett Koop,
- 03:20who as you know the surgeon General
- 03:23who wrote his article and smoking,
- 03:26which was revealing as to how
- 03:29smoking can actually cause harm so.
- 03:32Uh, my mentor actually worked with him
- 03:34on that particular project of the report.
- 03:36The Surgeon General's report on how smoking
- 03:39can be harmful because prior to that,
- 03:41it wasn't.
- 03:42So he's as a high stature in
- 03:45medicine and public health in the
- 03:47United States and he famously said,
- 03:50you know,
- 03:51drugs don't work in patients who
- 03:53don't take them.
- 03:54So I guess you can say,
- 03:56supplant that with C PAP.
- 03:58And so that's essentially my.
- 04:02One and only slide,
- 04:03so I will just finish the talk very quickly
- 04:07so that I can entertain some questions.
- 04:10Now it's just kidding,
- 04:12so I think it's very important
- 04:14to recognize that CPAP adherence
- 04:19not only informs how we can
- 04:25help patients symptomatology and
- 04:28prevent downstream consequences,
- 04:29but also.
- 04:32CPAP here and seems to be playing a big
- 04:35role in how we creating scientific evidence,
- 04:38so that's kind of unique to this
- 04:41particular area of study.
- 04:42It's just not downstream
- 04:45implementation signs,
- 04:46but it seems to also be affecting
- 04:48the scientific body of evidence
- 04:50that we are developing that can
- 04:52actually show that treatment of
- 04:53sleep apnea can improve outcomes.
- 04:55So the objectives for a talk today
- 04:58are two sort of from a health
- 05:01services research standpoint.
- 05:02Talk about some of the health care policies,
- 05:04UM, in this area,
- 05:05which I can tie into see Pepper,
- 05:07durin's talk about the determinants
- 05:10of adherence.
- 05:11Do a technology assessment and why
- 05:13we should be very familiar with
- 05:14technology and how that plays a role.
- 05:16And again, talk about healthcare delivery,
- 05:19how the implementation and delivery
- 05:21of healthcare can actually affect
- 05:23outcomes which are relevant to
- 05:25see Pepper Durance and downstream
- 05:27consequences as well as talk a
- 05:30little bit about future research.
- 05:32So you know what?
- 05:34What is the state of affairs?
- 05:36I mean,
- 05:36it's cheaper and it's really an issue,
- 05:38so this slide sort of gives you
- 05:41a geographic representation.
- 05:43This is essentially Geo.
- 05:44Linked data of over 170,000 people
- 05:47were part of a vendors database where
- 05:51you know the the C PAP Adrian stated
- 05:54goes and then we look at that data.
- 05:56The red dots are people
- 05:58are non adhering by CMS
- 05:59criteria and the blue dots are those who are.
- 06:02Adherent by Seamus Katrina, and as you know,
- 06:04this seems pretty resigned.
- 06:05A little bar or lower bar
- 06:07than what we would want.
- 06:08Which is, you know,
- 06:09greater than four hours of use and
- 06:11five nights a week rather than all
- 06:12nights a week or greater number of
- 06:14duration of views on a nightly basis.
- 06:16And in this particular study,
- 06:18we found that 53% of people in the
- 06:20real world by informatics study
- 06:22were non adherence to CPAP therapy.
- 06:25There are other data in this area
- 06:28to actually which are looking
- 06:29at a large big data research.
- 06:31It showed that.
- 06:33Adherence is probably closer up to 70%.
- 06:36One of the concerns we have with that
- 06:39methodology is is that it removed
- 06:41patients from the denominator.
- 06:43If they had zero adherence.
- 06:46In other words,
- 06:47if they see PAP machine registered zero,
- 06:49they did not count them in the
- 06:50denominator and therefore they
- 06:52didn't get counted in the denominator
- 06:53nor the numerator,
- 06:54and that may artificially increase
- 06:56the proportion of people or ignorant.
- 06:58I still think,
- 06:59and I've been asked a lot of
- 07:00questions about this number,
- 07:02but I still think.
- 07:03As long as you are methodologically sound,
- 07:06if you take all comers and then
- 07:08from an intention to treat aspect
- 07:10we have patients in clinic who
- 07:12have never used their CPAP,
- 07:13where they register zero.
- 07:14So those people were given a
- 07:16machine and they didn't use it,
- 07:18so they are non adherence regard and
- 07:20not you can't just take the people
- 07:22who use it for a few minutes for them
- 07:24to be counted in the denominator.
- 07:26And so when you look at,
- 07:28you know a healthcare policy, you know.
- 07:29And there's the national
- 07:30carrier determination,
- 07:31local carrier determination.
- 07:32And these are the number of beneficiaries.
- 07:35And the problem is,
- 07:36a lot of these policies are odds
- 07:39with each other.
- 07:40But the majority of the courage
- 07:41of determinate at local levels.
- 07:42So what is true in Arizona may
- 07:44not be true in your neck of the
- 07:47woods and vice versa because they
- 07:49operationalized differently,
- 07:50which creates geographic variation
- 07:52in health care delivery,
- 07:53which in of itself is a problem
- 07:56because it creates.
- 07:57Health disparities and as you all know,
- 08:00there is this 90 day rule or 12
- 08:02week rule or three month rule.
- 08:04How you wanna call it?
- 08:06But I guess 90 day rule is the
- 08:09common terminology and and and
- 08:11and the problem with this is that
- 08:13even though at that time when this
- 08:16then CD came out they expanded
- 08:18coverage to include home sleep
- 08:20studies and remove their two hour
- 08:23rule for the diagnostic aspect.
- 08:26Still stood by the fact that you cannot
- 08:28complete diagnose someone with sleep apnea.
- 08:29You do need to do this study,
- 08:30which we agree with.
- 08:32However,
- 08:33the 90 day coverage is is that
- 08:35as you are now,
- 08:36people don't are not here in my semen
- 08:38standards the machine benefits or
- 08:40loss of the CPI benefits loss and
- 08:42people start getting bills,
- 08:43even if they're part of a Medicaid
- 08:46program which causes health
- 08:48disparities or accentuates health
- 08:50disparities in this population.
- 08:52And of course they did say courage is it
- 08:56is allowed if the centers accredited.
- 08:58And the physician and or the
- 09:01physician are certified,
- 09:02and so I've been alluding to this
- 09:05health disparity aspect and then
- 09:07why it's important to sleep field
- 09:09is we've been facing a lot of.
- 09:14Headband lately with the Phillips
- 09:16device recall and previously, you know,
- 09:19meta analysis in JAMA as well as a
- 09:22couple of large multicenter trials,
- 09:24multi continent trials that were negative
- 09:27and we will be talking about that.
- 09:29But one of the movements is, as you know,
- 09:32in health care policy making is
- 09:34good with value based purchasing,
- 09:36but one of the problems with
- 09:38value based purchasing.
- 09:38So what is value based purchasing?
- 09:40So let's say if you're in the ICU.
- 09:43If you have a higher clabsi rate,
- 09:44you'll get dinged.
- 09:45You know if you have higher hospital
- 09:47read re admissions of patients
- 09:49with COPD and heart failure,
- 09:50you get dinged and you end up in a penalty
- 09:53box where they deduct you know .5% or 1%,
- 09:57or 1.5% if you are in the lowest quartile
- 09:59of that performance characteristic.
- 10:02But we know there's something
- 10:04called addition next,
- 10:05which is the disproportionate share
- 10:07of health disparity populations.
- 10:09So if your hospitals in New Haven is
- 10:12taking care of people more people who
- 10:14are in the lower social economic strata,
- 10:17you're going to have worse outcomes
- 10:19because there may be access to care issues.
- 10:22There may be ability to inability to pay
- 10:24out of pocket expenses and get medications,
- 10:27or there may be health literacy issues.
- 10:29And what will happen is these
- 10:31hospitals and these providers
- 10:33will get penalized even more,
- 10:34which means that those providers
- 10:36may migrate to more affluent
- 10:38territory areas and zip codes,
- 10:40in which case the health disparity in the
- 10:42lower social economic stratum ZIP codes.
- 10:44Will be actually worsened and and
- 10:49so this was actually a very telling
- 10:52article that talked about how you
- 10:54cannot tie metrics to UM reimbursement.
- 10:58Because if you did that,
- 11:02you can actually worsen health disparities.
- 11:04It may be an unintended consequence
- 11:06and that actually changed.
- 11:08For once,
- 11:09Medicare health policy and actually
- 11:11not using CPAP audience,
- 11:12for example as a valley based metric.
- 11:15Uhm for Valley based purchasing,
- 11:17so that's actually a good thing,
- 11:18so anyone who advocates for CPAP
- 11:21durans for value based care you
- 11:23have to be careful because you're
- 11:25going down a slippery slope fast,
- 11:27slippery, slope of accentuating
- 11:29health disparities for the poor.
- 11:32So we we had done a survey before.
- 11:34You know,
- 11:35looking at some of those provider
- 11:38based variables which turned 30
- 11:40patients where we took hard outcome
- 11:44of discontinuation of therapy.
- 11:46You know,
- 11:46we can always quibble about what is a
- 11:48meaningful difference in C PAP urine.
- 11:49Is it 30 minutes which is derived
- 11:52through consensus and propagated by the
- 11:54American Academy of Sleep Medicine?
- 11:56Or is it something bigger?
- 11:57So in this particular study,
- 11:59we just went with discontinuation
- 12:00of therapy because that's a pretty
- 12:02hard endpoint, right?
- 12:03I mean, if someone stops using pet therapy,
- 12:06you can say, oh, that's a meaningful change.
- 12:08It's either using it or not using it.
- 12:10It's not about 20 minutes or 30 minutes
- 12:12or extra hour or so on and so forth,
- 12:14and we use validated.
- 12:16Questionnaires to look at these variables
- 12:18of patient education risk perception,
- 12:20and that also confounders as well
- 12:23as patient satisfaction because
- 12:24that ties into healthcare delivery.
- 12:26And we found that centers that were
- 12:29accredited or physicians that were certified.
- 12:31If both of them are the case,
- 12:33there was actually a lower proportion of
- 12:36people had stopped using CPAP like 5%.
- 12:39If one of them.
- 12:41Where certified or accredited it's 7%,
- 12:44but if neither of them were certified in
- 12:47ways of accreditation or certification,
- 12:50you can see that the proportion of people
- 12:52who stopped using it is to actually 21%.
- 12:54So it's almost like a dose
- 12:56effect that you know.
- 12:57If you have care delivery given by
- 13:00people or certified and accredited,
- 13:02your risk of CPAP discontinuation is lower,
- 13:06so there's a nice dose effect
- 13:08between both being satisfied,
- 13:09being having the least amount
- 13:11of discontinuation rates.
- 13:12Uh, with none having the highest amount
- 13:15of discontinuation rate as a proportion.
- 13:18And one of the important you know
- 13:20aspects here is when we dive deeper
- 13:22and I'll go into sort of the multiple
- 13:25logistic regression model is is that
- 13:27you know the accreditation status
- 13:30was associated with the grade or
- 13:32odds or odds ratio of over 1.86
- 13:34of people discontinuing.
- 13:35And I just want to show you in
- 13:38step two there's nasal congestion
- 13:40and medication for this condition,
- 13:42which correspondingly either worsened
- 13:45the discontinuation of therapy.
- 13:48Are introduced the discontinuation
- 13:51of therapy,
- 13:53as evidenced by odds ratio of 1.57 and .28,
- 13:56suggesting that the nasal congestion
- 13:58factors or treatment for that is,
- 14:01uh,
- 14:01you know important determinant
- 14:03of Adrian's to see PAP therapy.
- 14:05So I'm going to skip this next slide
- 14:09to share that you know there's this
- 14:12outcome about satisfaction with
- 14:14physicians satisfaction with the center.
- 14:15It seems like a soft non biomedical outcome,
- 14:19but.
- 14:19Actually,
- 14:20value based care tomorrow is not going
- 14:24to go towards hopefully Tootsie Pop
- 14:26at your end because there would be a problem,
- 14:29but patient satisfaction is going to be a
- 14:32major driver in how valid is care morphs.
- 14:35In the future.
- 14:36It's not the volume,
- 14:38but it's the quality of care and one
- 14:39of the quality indicators you know.
- 14:41Besides,
- 14:42some of these other endpoints
- 14:43that you can suggest are the
- 14:46ultimate client satisfaction rate.
- 14:47And just like if you were to go buy a car,
- 14:49you know.
- 14:50The customer satisfaction is key,
- 14:52and similarly your patient satisfaction
- 14:54is going to be key and it's going to
- 14:56become a major driver in all of healthcare.
- 14:58That's why I wanted to point that
- 15:00out and few variables here that
- 15:02came out was that the time delay,
- 15:05the greater the time delay that lower
- 15:08the satisfaction and so access to care
- 15:10is an issue and discontinuation of therapy.
- 15:13So this is outcomes based satisfaction
- 15:15sometimes you may do the best job
- 15:17and taking care of your patients,
- 15:19but at the end result.
- 15:21If the outcome is not good,
- 15:22it's an undesirable outcome.
- 15:24The patients are going to say
- 15:27that they are dissatisfied.
- 15:28So I talked about the nasal
- 15:31congestion factor already
- 15:33and I think we tried to subscribe
- 15:35for towards this in our center.
- 15:37It just sort of came out of this
- 15:40health professions education for the
- 15:42national academies back in 2003,
- 15:44which is delivering patient centered care.
- 15:48And I just put you know,
- 15:50two domain areas such as how do you surveil
- 15:53for the surveillance for sleep apnea?
- 15:55And how do you promote CPAP adherence?
- 15:57But you need 5.
- 16:00Areas where a center needs and you
- 16:01know the staff need to have core
- 16:03competencies and which is being able
- 16:05to provide patient centered care,
- 16:07have an interdisciplinary team.
- 16:09Practice evidence based medicine and
- 16:12focus on quality improvements and
- 16:14have a huge amount of informatics.
- 16:17And of course during the pandemic.
- 16:18Times were big on informatics.
- 16:19A lot of telemedicine,
- 16:21telehealth happening in from a
- 16:23quality improvement standpoint.
- 16:24We actually see metrics of what our CPD runs.
- 16:26Dashboard looks like on a on
- 16:30a quarterly basis period.
- 16:32For example, a variable.
- 16:33I mean,
- 16:34I'm a measure that we have for
- 16:36our center as a metric,
- 16:38and of course we try to practice
- 16:40as best as we can.
- 16:42Evidence based medicine,
- 16:43although sometimes the evidence is still
- 16:45not available and we truly function
- 16:47doesn't transcend interdisciplinary
- 16:48team and I'll and I'll talk about
- 16:50what I mean by transdisciplinary
- 16:52as opposed to interdisciplinary.
- 16:54In just a bit.
- 16:55And but the key thing in all of
- 16:58this is patient centered care.
- 17:00And I know that one of the big gorillas in
- 17:03the room is this Phillips device recall.
- 17:06And this is where we truly are
- 17:10practicing patient centered care.
- 17:12And I'm going to speak about that and just,
- 17:14you know,
- 17:14just here,
- 17:15verbally and I don't have a
- 17:17slide because I I know there's a
- 17:20lot of nebulous details there,
- 17:22but we take a, you know,
- 17:23such variables in their camp,
- 17:24you know, as the patient using C PAP.
- 17:27Or they have a history of cancer,
- 17:30do a derived symptomatic benefit
- 17:33from the device,
- 17:34and if they had stopped therapy,
- 17:35did they become symptomatic?
- 17:37How bad are there other
- 17:40comorbidities outside of cancer risk?
- 17:42As well as whether they see
- 17:43particulate material,
- 17:44whether they are using ozone cleaner or not,
- 17:48and we actually do combined.
- 17:52Patient centered medical decision
- 17:54making with the patient or the
- 17:56caregiver and then we make a decision
- 17:59as to whether they choose with us
- 18:01with our advise whether they want to
- 18:03continue to use the therapy or not.
- 18:05Because we really don't have
- 18:07signs and evidence to guide some
- 18:09of our recommendations to them,
- 18:11so I know that question is going to
- 18:14come up so we do couch it in that manner.
- 18:17We do say that it sort of happened
- 18:19and so caution,
- 18:20and there's human cancer risk is.
- 18:22Improving and the particle
- 18:25a material causing problems,
- 18:27or at least as being reported in terms
- 18:29of particles that can be visualized.
- 18:30It's about points or eight person,
- 18:32and so we have a discussion and we
- 18:35find that 70% of our patients choose
- 18:37to continue the therapy device.
- 18:39And of course even in those people we try
- 18:42to get them in alternative new device.
- 18:46If it's more than five years.
- 18:48But even if less than five years as
- 18:51Janet was mentioning, we have had some.
- 18:53Luck getting some device for some people,
- 18:55and some people buy devices out of pocket.
- 18:57And so again, patient centered
- 18:59care in that manner combined.
- 19:01Medical decision making should be are not
- 19:04store and that is what we are practicing.
- 19:07So there is this topic about specialists.
- 19:10You know there are 47 million
- 19:11people with sleep apnea.
- 19:12Can specialist really take care of them?
- 19:14And that's a source of conversation
- 19:17as to how that can actually influence
- 19:19care in patients with sleep apnea,
- 19:22and especially see pepper durance.
- 19:25But this is study one of our
- 19:27fellows did along time ago.
- 19:29I'm showing that non specialists
- 19:32were more likely to give
- 19:34sedative nautic agent to as yet.
- 19:37Undiagnosed patient with obstructive
- 19:39sleep apnea that actually was
- 19:41associated with increased risk for
- 19:43motor vehicle accidents or near misses
- 19:45in those patients who received such
- 19:48non sitting sitting hypnotics where
- 19:50their LabCorp sleep was misconstrued.
- 19:53It's insomnia and instead of looking for
- 19:56sleep apnea, they're prescribed that.
- 19:57Now this is back in 2005 things probably,
- 19:59I mean, are much better now.
- 20:02However,
- 20:02this whole question about who should be
- 20:04taking care of patients with sleep apnea is,
- 20:07you know.
- 20:08Relevant and dumb,
- 20:10and it wasn't any of the other
- 20:12characteristics that made a difference
- 20:13in terms of years since graduation.
- 20:15Their perception about sedative,
- 20:17nautics and risks associated with them,
- 20:20or whether it's sleep was included
- 20:21in their medical school curriculum
- 20:23and whether they are knowledgeable
- 20:25about contraindications.
- 20:26None of them were significant
- 20:28between the groups of patients
- 20:29are either prescribed sedative
- 20:31or not prescribed sedative.
- 20:32And remember these are all people with
- 20:34undiagnosed obstructive sleep apnea.
- 20:35We're getting this additive, you know.
- 20:37Hypnotic and so why is that relevant?
- 20:41Because there's this talk, you know,
- 20:43and there's this really nice paper
- 20:45that was published out from Australia.
- 20:47Buy chocolates are and colleagues
- 20:49Nick Antiage.
- 20:51Uhm,
- 20:51you know.
- 20:52A finding that in a randomized control
- 20:54trial and primary care physicians
- 20:57were taking care of these patients.
- 20:59I was a specialist that they see
- 21:02PAP at Urance was non inferior
- 21:06in patients randomized to.
- 21:09Primary care in our end.
- 21:12Yeah,
- 21:12trained in the area of Sleep Medicine,
- 21:13but one of the concerns I had with
- 21:17this is that these RNS had about an
- 21:19average of 10 years of experience
- 21:21working in the field of sleep apnea.
- 21:24So if you have a RN that works
- 21:26for 10 years and sleep apnea feel
- 21:29you know you can argue that that
- 21:31person is actually a specialist,
- 21:32you know is on the job training
- 21:34as opposed to someone who did a
- 21:36fellowship and calls themselves that.
- 21:38And so when we did a meta analysis.
- 21:41Come come on, this particular issue.
- 21:44We found that by doing a you know
- 21:48systematic review that the CPAP
- 21:51adherence was indeed better in people
- 21:53in the published literature and
- 21:55sleep specialists were taking care
- 21:56of them rather than primary care.
- 21:58So I totally subscribe to a combined
- 22:01model of specialist working hand in
- 22:03hand with primary care physicians
- 22:05and there would be test shifting
- 22:08and collaborative interdisciplinary
- 22:09care being provided totally for it.
- 22:12But with the complexity that's
- 22:13evolving in the area of sleep
- 22:15apnea such as the Philips device,
- 22:17recall these risks associated
- 22:18associated with that as well as I
- 22:21work being done at Yale in terms of
- 22:23looking at loop gain and arousal
- 22:25threshold and different approaches
- 22:26to managing patients with sleep
- 22:29apnea ranging from hypoglossal nerve
- 22:32stimulation to medications targeting
- 22:35the controller respiratory control.
- 22:39Are you really getting into it?
- 22:41Pretty complex area where there needs to be.
- 22:43Perhaps the easier cases handled our
- 22:45primary care and the more complex
- 22:47cases handled by a specialist,
- 22:49so it's going to be something that
- 22:53more research needs to be done on.
- 22:55So as segue to determinants of adherence
- 22:59here and and this is sort of the slide
- 23:03with that where you have domains
- 23:05of therapy based patient based and
- 23:07health care delivery based variables and.
- 23:10You know,
- 23:11under patient there's the psychological.
- 23:14There's a physical and the social and
- 23:16actually hadn't updated my slide in awhile.
- 23:18But after Andres paper get published,
- 23:21I added the lower arousal threshold
- 23:24as a physical factor that's
- 23:26contributing to see patterns.
- 23:28And some of these are reversible,
- 23:31some of them are obviously or not,
- 23:33and some of them can be targeted,
- 23:34and so the areas that are highlighted
- 23:37in red become our targets.
- 23:39If you want to really improve,
- 23:41see Pepper Durance.
- 23:42In patients with sleep apnea,
- 23:44these are the determinants
- 23:46that we should be targeting.
- 23:48And so just to.
- 23:52Give a refresher and all many of you
- 23:54know all this data by the back of your
- 23:57palm and you know auto PAP therapy,
- 24:01at least the last cocaine review which
- 24:03is again dated suggested that it may
- 24:06actually help a subgroup of patients.
- 24:08Although bilevel,
- 24:09PAP and patient titrated CPAP
- 24:11or humidification had no effect,
- 24:12but CBT emerged and educational support,
- 24:17behavioral support psychological
- 24:19support has been shown.
- 24:22Uhm,
- 24:22to have a pretty high signal but
- 24:25there were concerns that the amount
- 24:28of data there was smaller and so the
- 24:31confidence intervals were large.
- 24:33And of course it's a date, admit,
- 24:34analysis and and and and so.
- 24:38A segue into some other physician variables,
- 24:41again,
- 24:41that can affect the puppet you're insane.
- 24:43This is a study that we did a
- 24:45gosh back in 2005 where we found
- 24:48out that time out of C.
- 24:50Pap's were given only four percent
- 24:52of the times. 96% of the time.
- 24:53So whether CPAP Bipap and you know,
- 24:55you can argue that it's going
- 24:56to be pretty topsy turvy now,
- 24:58so a lot has changed and at that
- 25:00time 30% of physicians said
- 25:01that they never prosper auto,
- 25:02CPAP devices and many were
- 25:04not aware of all the
- 25:06contraindications for auto CPAP.
- 25:08Dumb and dumb. In other words,
- 25:11their knowledge base and dumb and
- 25:13patient physicians with who actually
- 25:15had a greater volume of patients with
- 25:17sleep apnea practice were more likely
- 25:19to prescribe odyssey type devices.
- 25:21And so, and at that time back in 2005,
- 25:24half them, half the physicians did not
- 25:27request or insist on adherence monitoring,
- 25:29because at that time you need to actually
- 25:32ask for CPAP unions device to be attached
- 25:34to a machine like a modem or something.
- 25:39Which was attached to
- 25:40the back of the machine.
- 25:42So if you probably I'm not even
- 25:44seeing what it looks like,
- 25:46but you can just see that you know
- 25:49in this span of about 16 years the
- 25:52field of Sleep Medicine has rapidly
- 25:54changed where it's universal adherence,
- 25:56monitoring and and so it's quite
- 25:59different as to how we manage.
- 26:02You know, patients with sleep apnea.
- 26:05So this is again a cornerstone in this area.
- 26:09Self supported, reported.
- 26:10See patterns or Smiths significantly,
- 26:13and the C PAP usage people always
- 26:15or estimate how much they're using.
- 26:17And so therefore self reported
- 26:19stupider insufficient,
- 26:20and that's why we need to monitor
- 26:23people or 100% for their C Pap when I
- 26:26have resident physicians and medical
- 26:28students rotate with us and sleep clinic,
- 26:31I do end up by asking them, you know,
- 26:33with what clinic did where you at before
- 26:36you're rotating in Sleep Medicine.
- 26:38And I'll say, oh, you know,
- 26:40I wasn't in Thomaston clinic,
- 26:41or I was in the primary clinic.
- 26:43And I asked them,
- 26:45did you find out whether this person
- 26:48who was on a cholesterol lowering
- 26:50medication or and hypertensive
- 26:52or who's taking insulin for their
- 26:56diabetes and inhalers for their COPD?
- 27:00Did you monitor their adherence and I
- 27:04would say 99% of the time the answer is no.
- 27:07And then the question is do you?
- 27:09Did you withhold therapy in any one of them?
- 27:12A diabetic.
- 27:13Is not taking insulin to withhold their
- 27:16insulin because they're non adherence?
- 27:19And again, universally, dancers.
- 27:22Wow. No, we would never do that.
- 27:25So when I submit to you is is that.
- 27:29Sleep Medicine is the only field
- 27:32where we withdraw CPAP benefits.
- 27:34UM,
- 27:35if patients are nonadherent and it's
- 27:37just as you know, not just for CMS,
- 27:41Medicare,
- 27:41Medicaid,
- 27:42but it also is taken up by other
- 27:44third party insurance.
- 27:46So I know the American Thoracic society,
- 27:48you know,
- 27:49part of a some of you are part of that task.
- 27:52Force policy document is being written
- 27:55that hopefully will go and change this,
- 27:57but I was on a call with seems innovation.
- 27:59Center as a KOL,
- 28:01I'm talking to them about what ails
- 28:04the sleeper in area and come along
- 28:08with people from AHRQ and Corey and.
- 28:14QMP Corey were aghast that
- 28:17such a policy existed.
- 28:19It's only see Ms Innovation
- 28:20Center and also the CAG Group,
- 28:22which is the advisory group
- 28:24that determines what is covered
- 28:25by Medicare and Medicaid.
- 28:27And of course,
- 28:28all insurances follow Medicare Medicaid
- 28:29as to what is coverage,
- 28:31so the coverage determinations
- 28:32being made is done by device cagri,
- 28:35and so they were on the call as well.
- 28:37And they seem to know the policy, they said.
- 28:39It's not even set by the Department
- 28:41of Health and Human Services.
- 28:43It's actually a congressional law.
- 28:44That was passed in 2001 that has been
- 28:47not implemented for the longest time,
- 28:49but in the year 2016 or so it
- 28:52became implemented, and so you know,
- 28:54there are lots of laws that are
- 28:56not implemented as you know,
- 28:57but they dusted it out from 2001
- 28:59and decided to implement it.
- 29:01So this 90 day rule actually has
- 29:04its theology to this archaic
- 29:08lauders possible Congress.
- 29:10So the only way to go and change it is
- 29:12actually go to Congress and change the law.
- 29:15It's not American Medicaid,
- 29:16so they said the more data that you
- 29:19folks can generate that shows the
- 29:21puppeteer and is harming these people
- 29:23and making them not use the device,
- 29:27sends that data and but also lobby
- 29:29so that you can actually go and
- 29:31change the policy in the land.
- 29:33Then there's no other chronic medical
- 29:35condition in the United States of America.
- 29:38Where treatment is withheld
- 29:39of people are non Indian.
- 29:41The only only condition is obstructive
- 29:44sleep apnea and it's based on CPAP
- 29:47nonadherence and so that's why you
- 29:50know we're talking about it here and
- 29:53so let's telemonitoring you know we
- 29:55just did a sea change in the way
- 29:57we practice medicine and I know
- 29:59at one point in time you all were
- 30:01practicing our person telemedicine VR.
- 30:03Right now I would say about 85, fifteen 85%.
- 30:08In person and 15% Tele medicine.
- 30:12Although that number keeps fluctuating
- 30:14of course,
- 30:15as we continue to go up on the
- 30:18foot surge and and this was done by
- 30:21Carl Stepnowski at UCSD and found
- 30:23that at that time that it was only
- 30:25as effective as usual care.
- 30:27But there's a question as to whether
- 30:29there's a underpowered study,
- 30:30which is 45 participants,
- 30:32and so one of the questions that keeps
- 30:35getting asked is where is the evidence?
- 30:37Why?
- 30:37Why?
- 30:38Why should we treat our circle sleep apnea?
- 30:41You know,
- 30:41it's just before I started making tacos.
- 30:43Just talking with Janet about
- 30:45you know we're having some basic
- 30:48discussions with patients when
- 30:49we're doing the Phillips recall.
- 30:51Like why are we treating you again?
- 30:53Oh yeah, I know,
- 30:54we're treating you because
- 30:55if you stop using it,
- 30:56you're sleepy or you have comorbidities.
- 30:58We're having that discussion now,
- 31:01but when you go to somehow in the
- 31:04HRQ released, you know, as you know,
- 31:06a document which said that why should
- 31:08we treat people with sleep apnea?
- 31:10Because there's no evidence in
- 31:11the field of sports that well,
- 31:13here's data.
- 31:14Uhm, you know this is the HYPOCRIT trial.
- 31:17This is the Spanish multi collaborative
- 31:19group which actually showed that
- 31:21you have reductions in 24 hour
- 31:24blood pressure with the mean,
- 31:26and that's solid blood pressure and you
- 31:28know when you compare that with blood
- 31:30pressure of meta analysis that have
- 31:32been done using inhabitants of these,
- 31:34you know data very, very, you know,
- 31:38compareable and so patient level strategies.
- 31:41Have resulted in a drop in blood
- 31:43pressure of 3.9 millimeters mercury,
- 31:45and that's very comparable to what
- 31:47was seen in this multicenter trial.
- 31:49Yes, it is true that this is for
- 31:51people with resistant hypertension
- 31:52and obstructive sleep apnea,
- 31:54so it's not all comers,
- 31:56but you can see that you know that C.
- 31:59Pap is beneficial in improving
- 32:01blood pressure, and as you know,
- 32:03with every millimeters of mercury I
- 32:04don't need to tell this group that
- 32:06you reduce their mean blood pressure.
- 32:08You introduce a lifetime risk
- 32:10for cardiovascular events.
- 32:11Including you know,
- 32:12heart attacks and strokes, so, uh,
- 32:13this these are real numbers and their
- 32:16compara bulto and hypertensive medications.
- 32:19And so when we hear about,
- 32:21you know where's the data?
- 32:22You know at least we have
- 32:24data in hypertension.
- 32:25Now Pastor air pressure therapy.
- 32:27You know in the form of anonymous passers,
- 32:30therapy or bilevel PAP therapy.
- 32:31In the home there's strong data,
- 32:34again, not from the US,
- 32:36from Europe and the UK.
- 32:40In a multicenter study by clean
- 32:42and all and Murphy and colleagues
- 32:45showing that when you apply an IPV
- 32:48or an Ivy in patients with COPD,
- 32:50you can reduce mortality.
- 32:54You can improve survival and so
- 32:57so data showing that posterior
- 32:59pressure therapy in these people.
- 33:02That Pastor impression therapy
- 33:04can make it then.
- 33:06On survival,
- 33:06but somehow in the US we haven't
- 33:09done a large multicenter trial
- 33:11in patients with CMPD,
- 33:13and so that's really a question
- 33:15as to what the strategic.
- 33:17Our plan is and what does the
- 33:20strategic plan support so many
- 33:22investigators in this area?
- 33:23You know, Jerry Kraner and Nick L.
- 33:26You know, I, you know I myself.
- 33:28We made a lot of attempts at doing.
- 33:31Gosh,
- 33:31twenty $30 million grants to actually
- 33:33address probably one of the top five
- 33:35reasons for death in the United
- 33:36States of America, which is COPD.
- 33:38And we saw can't get that trial done
- 33:41in EU S because why is that important?
- 33:43It's important because.
- 33:46Research, however,
- 33:47that level of evidence is done
- 33:49outside of the US.
- 33:50Don't change healthcare policy.
- 33:51This is should.
- 33:52Making the US you need a study done
- 33:54in the US to change healthcare
- 33:56US health care policy and it is.
- 33:59We are remiss and not doing multi
- 34:01center trials and not just COPDN IV.
- 34:04But not doing a large multicenter
- 34:06trial on sleep.
- 34:08Happy.
- 34:08And how we can improve
- 34:09outcomes because you know,
- 34:10you know this is a meta analysis showing
- 34:13that you know with the published literature,
- 34:15not just those two studies,
- 34:17you can reduce mortality.
- 34:18The hazard ratio mortality is lower,
- 34:21but why are we set back?
- 34:22Why can't we do this multicenter trial?
- 34:24Well,
- 34:24we actually have the odds piled up against.
- 34:26As you know,
- 34:27this is one of the hits that
- 34:29we took. You know, one of gosh,
- 34:31four heads that we've taken
- 34:32in the past five years.
- 34:34You know, starting with the SAFE study,
- 34:36the Soviet chef study,
- 34:38and other JAMA Meta analysis,
- 34:40and now the AHRQ report.
- 34:42And then the Phillips recall,
- 34:45and so in this particular study,
- 34:46this study is, she know,
- 34:47did not show improvement
- 34:49and survival similar to the
- 34:51RIKHOTSO trial and other trials.
- 34:53But when you do an analysis,
- 34:55secondary analysis,
- 34:56or even our priority stated analysis,
- 35:00where we look at the only people
- 35:02who are adherents and you can
- 35:03see that you can actually help.
- 35:05Show that there is a need,
- 35:06a signal and the signal is
- 35:07actually stronger for strokes,
- 35:09and I know that you know,
- 35:10uh, klar,
- 35:11yaggi and Don Bravata have
- 35:13published in stroke as well,
- 35:15showing that the signal is actually
- 35:17stronger in as being able to use
- 35:20plaster pressure therapy and sleep
- 35:22apnea to make a dent there and
- 35:24reduce the risk for having a stroke.
- 35:27Our repeat stroke after Tia A but,
- 35:30but of course,
- 35:31if you don't put that as a primary end point,
- 35:34you know all these secondary in points.
- 35:36It goes a wash even if you had
- 35:38stated that adjusted analysis,
- 35:40our priority,
- 35:41and of course that's why
- 35:42they put sleepiness score,
- 35:44which showed significant
- 35:45improvement in these people.
- 35:46Unlike the study done by Kushida
- 35:49effective CPAP on sleepiness,
- 35:51which was again a negative study,
- 35:53whereas in the same study it
- 35:55showed that sleepiness doesn't need
- 35:56improve and but of course it's.
- 35:59You know if you go use the FDA,
- 36:01you know rubrics.
- 36:02If it's not your primary
- 36:04endpoint or if it's not.
- 36:06If you don't hit your primary
- 36:07end point is a positive.
- 36:08Every other endpoint is out the door.
- 36:11You know,
- 36:11by evidence based medicine and by FDA rules,
- 36:14and so this is nobody
- 36:16speaks about this as much.
- 36:17Because yes,
- 36:18it was a native trial for criminal outcomes,
- 36:20but sleepiness did improve.
- 36:23And hospital anxiety depression scale
- 36:26improved as of 36 in EQ5D as quality
- 36:30of life indicators also improved.
- 36:32But what was very concerning
- 36:34is that in the SAVE trial she
- 36:37knows multi continent study.
- 36:38That adherence was in about
- 36:422.8 hours or so for the entire
- 36:44group in their treatment arm.
- 36:472.8 hours. Let's go back to you
- 36:49know whatever it SI Group said.
- 36:51If you don't use drugs.
- 36:53I'm going to help,
- 36:54and so if you don't use a C PAP
- 36:57in intention to treat analysis,
- 36:58we're going to draw a blank.
- 37:00So C pap insurance not only is
- 37:02important for patient centered care,
- 37:03but it's also affecting our ability
- 37:06to develop the scientific body
- 37:09of literature for us to address.
- 37:11And get third party payers to pay
- 37:13for it or be able to give this
- 37:15device to people and so that's
- 37:17where they you know that's why
- 37:19I see Papa John's assumes even
- 37:21more important than you know we.
- 37:23We talked about the service
- 37:24of trial and you know
- 37:26there are issues of the Soviets have trial
- 37:29which you know skip over here and to go
- 37:33to the meta analysis where there was,
- 37:36you know compare PAP therapy versus control
- 37:39or preventing cardiovascular events.
- 37:40Of course this came.
- 37:42You know well before the AHRQ
- 37:43report and they essentially drew
- 37:45the conclusion that there is no,
- 37:47you know, benefit to PAP therapy,
- 37:50but in the four trials where more than
- 37:53four hours of adherence were achieved,
- 37:55there was, you know, relative risk reduction,
- 37:5842% reduction in relative risk,
- 38:01and so, again,
- 38:02we cannot cherry pick those studies,
- 38:05but some other problems with this meta
- 38:07analysis was a heterogeneity of intervention.
- 38:11There's a heterogeneity.
- 38:12Of population, if you look at pick ATS,
- 38:14the event rates were low,
- 38:16which the authors themselves
- 38:17admitted to and then there was
- 38:19undue influence on one of one study.
- 38:21Essentially 73% of the three
- 38:24or 56 events were in.
- 38:28You know studies.
- 38:29You know there were contributed
- 38:31by the same study.
- 38:32So, uh,
- 38:33when you do a meta analysis,
- 38:35you have to look for a new influence,
- 38:36and so unfortunately there was undue
- 38:39influence of one study in the outcome of
- 38:42this meta analysis and and that is an issue.
- 38:45So what is being done about it?
- 38:47You know this is a last Cochrane review
- 38:50showing that you can do educational
- 38:53supportive behavioral interventions.
- 38:54You know all three different categories.
- 38:56Or the intervention.
- 38:57Could you know submit?
- 38:58All of these three inside of them can
- 39:01indeed improve adherence in these people,
- 39:04and but when you,
- 39:06when you look at how many there
- 39:09are in clinicaltrials.gov that are
- 39:11focused on improving, see paper.
- 39:12Durance is only 6.
- 39:14Yes, we live in an era of medications,
- 39:17addressing loop gain, arousal threshold.
- 39:19Yeah, have a glass of nerve stimulation.
- 39:23No, I don't know uh neck collars,
- 39:25you know,
- 39:26no sprays that are going to
- 39:28be addressing sleep happening,
- 39:29but right now when you have a bad
- 39:31patient diagnosed with sleep apnea,
- 39:32your choices are three which is C pap,
- 39:35you know?
- 39:37Hypoglossal nerve stimulation story,
- 39:38not in that order,
- 39:39but dental device and I haven't
- 39:40lost in isolation.
- 39:41So that is where we are in so right now,
- 39:45until all of that data comes to
- 39:47the forefront, you know.
- 39:49This is still something that is an
- 39:51issue that needs to be addressed,
- 39:54and so this whole concept of adherence,
- 39:56you know in certain fields it's
- 39:59not transposable to other fields.
- 40:01You know this is actually a work
- 40:02done by Lynn Gerald in our group.
- 40:04Here you know she did a large
- 40:07trial in children in Tucson,
- 40:09AZ and try to see what was the
- 40:11relationship between asthma control on
- 40:13the Y axis and adherence to the X axes,
- 40:16and she found there's no relationship.
- 40:18You know, the more adherent they are.
- 40:19Yes, well control in a questionnaire.
- 40:21Symptomatology was similar.
- 40:22Uhm,
- 40:23that's probably because you know
- 40:25the more severe asthmatics are gonna
- 40:27be taking more of the medications
- 40:29and vice versa,
- 40:30and it may even itself out.
- 40:33But in sleep, you know this is in a really
- 40:35nice paper and work done by Terry Beaver.
- 40:38But of course, I'm citing a review article
- 40:40showing that there is a dose effect you know,
- 40:42between you know in within C PAP use,
- 40:45and there's a some of them flatten out.
- 40:47Some of them seem to be going up, and so.
- 40:50And they don't show a flattening of
- 40:53that curve, suggesting that there
- 40:55is indeed a continuous dose effect.
- 40:57So more is indeed better in
- 41:00the field of C PAP therapy.
- 41:03And so apologies for that and so
- 41:06there is data showing that, UM.
- 41:11Cognitive behavioral therapy
- 41:12has a pretty strong,
- 41:14powerful effect as in the study,
- 41:17but the problem is is that you know there are
- 41:21small studies and they're not well powered,
- 41:23so more needs to be done along those lines.
- 41:26So I'm going to flashback to the
- 41:28first slide I showed you in terms
- 41:30of C pepper and some problem.
- 41:31It's actually much higher than what's
- 41:33the estimated by certain studies,
- 41:35and if you look at randomized control trials,
- 41:38the proportion is actually worse.
- 41:40In the real world studies,
- 41:41actually,
- 41:42if you take the acts and look at them,
- 41:44the audience in the treatment
- 41:46arm is actually worse than 47%.
- 41:50Here 53% are non Indian,
- 41:5347% are different and it's actually
- 41:54worse in in in clinical trials if
- 41:56you do it as a meta analysis and
- 41:59that's been published by folks in
- 42:01EMT who want to push for why you
- 42:02know people should be getting,
- 42:04you know up every surgeries or
- 42:06hypoglossal nerve stimulation.
- 42:08But then you take the ZIP code.
- 42:11To which the CPAP devices are Geo
- 42:13link and you plug in their median
- 42:15income of the ZIP code you see a huge
- 42:17health disparity and you know you
- 42:19see that as you go up on the median
- 42:22income quartile from one to four.
- 42:24A lot of people have shown this data,
- 42:26you know Jesse Baker,
- 42:28and has shown this in New Zealand.
- 42:31Pepper and company are showing
- 42:33that in the home PAP study UM and
- 42:36and so this is not novel.
- 42:38What we had done.
- 42:39But it was database which was nationally
- 42:42representative and we're able to actually
- 42:45see the socioeconomic data and show
- 42:48step changes in adherence across this.
- 42:50And this is very relevant because
- 42:51we live in a time where there's
- 42:53more recognition of how this
- 42:55Paris during the code pandemic,
- 42:56how it disproportionately effects
- 42:59communities in the lower SES and therefore.
- 43:02You know we need to do more,
- 43:04and so that's the reason why we went
- 43:06with a patient centered approach
- 43:07and doing behavioral support,
- 43:09which is focused on promoting stuff,
- 43:12efficacy,
- 43:13promoting outcome expectancies and risk
- 43:16perception and also activating the patient.
- 43:19Being able to actually make them
- 43:22take charge of their health care,
- 43:24combine them with the patient
- 43:26who's naive to the PAP therapy and
- 43:30user interactive voice response.
- 43:32Because I can tell you that
- 43:34the lowest paid employee
- 43:35in our sleep centers are always at the
- 43:37tip of the spear, they are incoming.
- 43:41All kinds of calls that are coming to them.
- 43:42So what we have adopted
- 43:44in this is I interact.
- 43:46Voice response approach that it actually
- 43:49distribute those calls to the respective
- 43:51person based on an algorithm through
- 43:53what the patient says that they want.
- 43:56So it'll go to resperate happens.
- 43:57It's a question about our ASP.
- 43:58It'll go to a nurse if it's about nasal
- 44:01congestion, it'll go to a support person.
- 44:04NYC where so and so we did this
- 44:06research differently, right?
- 44:07A lot of times we listen to a talk.
- 44:09We get a spark in our brain and say, oh,
- 44:12you know what I'm going to actually go study
- 44:13that that's not how the study was done.
- 44:15This is peak worries methodology, which
- 44:17is essentially research done differently.
- 44:19Where we actually said, OK,
- 44:21what is the burning issue in
- 44:22the sleep apnea field?
- 44:23Let's get all of these stakeholders,
- 44:25purchasers, payers principle investigators,
- 44:27the ASM American Sleep Apnea
- 44:29Association is a patient public
- 44:32advocacy organization providers,
- 44:33various kinds of providers.
- 44:35And patients and we brought them
- 44:37together and said, you know,
- 44:39how would you design this study?
- 44:41What are the outcomes that are important?
- 44:42How would you rank these outcomes
- 44:44and guess what?
- 44:45They ranked as number one.
- 44:46They ranked as global patient
- 44:48satisfaction of care dollars number one.
- 44:49And there was concordance amongst the
- 44:52various stakeholders that they agreed
- 44:54that this would actually be a top
- 44:56priority because patients are smart.
- 44:58They know when they got good care and
- 45:00when they didn't get good care and so
- 45:02we can come up with weird metrics.
- 45:04But global patient satisfaction.
- 45:06Emerged as our metric.
- 45:08And and then we got this what
- 45:09we call non binding input.
- 45:11You know if you're bidding for a home,
- 45:13you know you're on the hook.
- 45:16You know if they say you need
- 45:17to fix that shingle,
- 45:18you need to fix the shingle,
- 45:19otherwise you can't sell the home,
- 45:20whereas that's binding.
- 45:21Whereas here this is non binding input
- 45:24so we got seems Innovation Center.
- 45:26We got United Healthcare medical directors,
- 45:30you know of Aetna and everybody on
- 45:34as you know pairs to get their input.
- 45:38And they could give input without having
- 45:39to buy the product at the end of the day,
- 45:41they don't have to buy the product
- 45:42and so and again we got input from
- 45:44then and the conduct of the study.
- 45:46How we can actually do better recruitment
- 45:48as well as how we could do a better job
- 45:51with dissemination and implementation.
- 45:53And you know this is a study that
- 45:55was powered for about 260 people that
- 45:58were randomized to these two arms and
- 46:00there was an attention control arm
- 46:02besides the PD IVR which called Pure
- 46:05driven intervention with interactive
- 46:06voice response as compared to.
- 46:09Attention control,
- 46:10and when we randomize them,
- 46:12we found that global patient satisfaction
- 46:15was better in the PDI VR arm.
- 46:18You know we can have a discussion as
- 46:20to how significant that is or not.
- 46:22And this is the table that goes with that.
- 46:25But the C5 adherence data was actually,
- 46:28you know, better. Again,
- 46:29in terms of minutes you spend night or
- 46:31partial nights used greater than four hours.
- 46:33And again, lot of you know 50 minutes mean
- 46:36you know it's 50 minutes mean anything.
- 46:39And so that's why we looked
- 46:41at number needed to treat.
- 46:42In other words, what we looked at.
- 46:44The outcome was how many people
- 46:45did you need to treat with a peer
- 46:48driven intervention to prevent one
- 46:50person from losing CPAP benefits?
- 46:52In other words,
- 46:53but one person that did not meet
- 46:56the Medicare CMS 4 hour rule and
- 46:58therefore would have lost their
- 46:59CPAP benefit as a result of that.
- 47:02So we found that at the NT was nine.
- 47:05So if you actually ran,
- 47:06you know treated nine people with its PDI VR.
- 47:10You prevent one person from outright
- 47:12losing the C PAP therapy device,
- 47:14and so we thought that that
- 47:16was significant and and.
- 47:18And also we looked at measures
- 47:21of care coordination.
- 47:23And health care services and delivery and
- 47:25found that it was superior in this group,
- 47:28so I'm going to just touch
- 47:30upon technology assessments.
- 47:31UM, and I know I'm short of time, but.
- 47:36Uh,
- 47:36you know,
- 47:37know your device auto CPAP therapy
- 47:39devices or perform very differently.
- 47:42You know we have issues with the
- 47:44device recalls right now,
- 47:45but their performance is also very
- 47:46differently.
- 47:47Is a bench studies that we've done
- 47:48in the past during that,
- 47:50given the same set of conditions with
- 47:53a Starling resistor and resistor on
- 47:55a bench model with artificial lung,
- 47:58and that these devices perform
- 48:00differently and that air leak
- 48:02is a big issue with how they
- 48:04function or not function and.
- 48:06We showed that in both the bench
- 48:08model as well as when we did a
- 48:11human study and looking at idea
- 48:12in an Indian patients not with
- 48:14this level of sophistication that
- 48:16you know Andre is injected with
- 48:19your arousal thresholds and such.
- 48:21And we found that you know air
- 48:23leak was higher in the group.
- 48:25There was non adhering to supposed
- 48:27to adhere and so you know having
- 48:29a good mask fit is important and
- 48:32addressing that is important
- 48:34and I know I'm preaching to.
- 48:36Group that knows this.
- 48:39You know,
- 48:40by the back of their hand,
- 48:41so you know there are data out there,
- 48:43even though it analysts were
- 48:45not supportive that he did.
- 48:46Humidifiers reduce our effects provided
- 48:48urine's as well as nasal pillows.
- 48:50But there are so you know,
- 48:52single studies that are out there.
- 48:53Although they didn't make up up to
- 48:56a measurable level in meta analysis
- 48:59and this is work done my route,
- 49:01you know Buddy Roger,
- 49:02who who was you know who's in Harvard Nam,
- 49:04but you know was that you know
- 49:07to sign in at the uofa before.
- 49:10Where he showed that you know,
- 49:11early CPAP use predicted subsequent years.
- 49:13Why is that important?
- 49:14Because identifying those early
- 49:16CPAP non ideers that's when you can
- 49:18bring in your limited resources like
- 49:20appear to intervention into play or
- 49:22any other intervention that you have
- 49:24into play so that you can actually
- 49:26change the trajectory of non adherence
- 49:28as opposed to giving everybody that
- 49:30resource which is finite and limited.
- 49:32You'd be able to see how they do in
- 49:34the first seven days of adherence and
- 49:36bring that particular intervention into
- 49:38play and that's why that predictor of CPAP.
- 49:40Non adherence or adherence
- 49:42becomes relevant and important.
- 49:45I'm going to skip some slides here.
- 49:48Uh. And sorry,
- 49:50I just wanna make sure I come,
- 49:54you know, give some time but end
- 49:56with these couple of slides.
- 49:58What is was disappointing when we
- 50:00looked at ZIP code based median income
- 50:02quartile based non adherence is that
- 50:04when we looked at you know and this
- 50:06is about 170,000 people going back
- 50:08about 17 years and when we looked at
- 50:11them we found that when you put them
- 50:13in quartiles the people are the lowest
- 50:16income quartile which is the blue symbol.
- 50:19Uhm,
- 50:20continue to lag behind the others
- 50:21and you can see that between the
- 50:233rd and the 4th income quartile
- 50:25there is a steep drop off.
- 50:26It's almost like a hemoglobin
- 50:28dissociation curve or something,
- 50:30and the shoulder and,
- 50:31and I think that's about the time
- 50:34that out of pocket pay and expenses
- 50:36to be able to buy a mask that works
- 50:40for them becomes a factor for them.
- 50:41And people are picking and choosing
- 50:43us whether they're going to pay
- 50:44copay on their blood pressure,
- 50:45medications, heart failure,
- 50:47medications, and diabetes medications.
- 50:49Our father CPAP device,
- 50:52which has been withheld from them
- 50:55for nonadherence and So what is
- 50:57was doubly disappointing that the
- 50:59Affordable Care Act and Medicaid
- 51:01expansion in the year 2014 had made
- 51:04no dense in health disparities.
- 51:06So this is still an area that requires
- 51:09study and interventions to address that,
- 51:12and when we you know in this particular
- 51:14graph and you zoom in when you look at
- 51:17these quartiles and you do a Kaplan
- 51:19Meier for when they start becoming.
- 51:21At your end or non idea and you can
- 51:22see that they curve start display
- 51:24it on 90 days and then they start to
- 51:27display even more 120 days in focus
- 51:28groups with RDM we find that they
- 51:30give almost a 30 day grace period even
- 51:33though that there's the 90 day rule
- 51:34they give a call at the 90th day or so.
- 51:37Did they get to it and then they give
- 51:40multiple calls saying hey we're gonna
- 51:41report you to collection agency or
- 51:43they send them a bill in the mail
- 51:46or they you know I'm keep badgering
- 51:48them and so you can see that's when.
- 51:51It actually plays even more,
- 51:53and so when we look at a
- 51:55difference in difference analysis,
- 51:56we find that those two time points
- 51:5890 and 120
- 51:59days is where that health
- 52:01disparity becomes more apparent,
- 52:03and so I can't think of something
- 52:06more telling we came upon across
- 52:09this innocentis manner that this
- 52:11is ties to a man made rules,
- 52:13so it's hard enough to use an
- 52:16external device that requires
- 52:17behavioral change and use it nine
- 52:20play as opposed to an implanted.
- 52:21Device that needs to be turned on.
- 52:23UM, that requires behavioral change.
- 52:27Uhm, on top of that we have these
- 52:29man made rules that exist only
- 52:31for the sleep apnea condition.
- 52:33So I think we need to do a lot in
- 52:36this area to actually address there's
- 52:39some issue which is affecting the
- 52:42signs and affecting patient care,
- 52:44and we repeatedly keep doing the
- 52:47same studies without actually
- 52:49having strong robust CPAP adherence
- 52:52and proven CPAP adherence.
- 52:55Promotion interventions in the
- 52:57intention to treat or intervention
- 52:59arm as long as we keep doing that,
- 53:01we're not going to generate the data.
- 53:04Uh, to show you know what we
- 53:06would like to show up,
- 53:08so I'll stop there and I I don't.
- 53:11I'm sorry I didn't get
- 53:13much time for questions,
- 53:14but I appreciate your attention,
- 53:17so Janet handing it back to you.
- 53:21Thank you so much and that
- 53:22was absolutely outstanding.
- 53:23I mean, you really need just
- 53:25such a case for why it's so
- 53:26important to treat sleep apnea.
- 53:28Why it really needs to be approached from a
- 53:31patient centered and team based approach,
- 53:34and I think that's really key.
- 53:36You know, with a new man,
- 53:38you made a very good case for what you
- 53:39know with health disparities and where
- 53:40I think we're seeing that more and more,
- 53:42you know, at one point prior to the pandemic,
- 53:45I think some of our DNS as well as
- 53:48we at Yale had we're trying to think
- 53:50about and start a compassionate.
- 53:51CPAP program to just try to get these
- 53:54patients you know at that 90 day,
- 53:55you know because there are some
- 53:57people who really obviously can't
- 53:59afford you know those copays,
- 54:00and with the pandemic it seems that a
- 54:02lot of those programs have shut down
- 54:05and have it really started back up.
- 54:07What's been your experience with
- 54:08those kinds of programs?
- 54:11Our experience has been the same.
- 54:12There's a lot of concern
- 54:14about infection control.
- 54:15It existed even before.
- 54:17Must be honest,
- 54:18we use a lot of refurbished CPAP.
- 54:20There are local support groups,
- 54:22non profit centers that was actually
- 54:25refurbishing CPAP in issuing them.
- 54:29They actually couple of them shut
- 54:32down under threat of a lawsuit for
- 54:34spread of infection and this was
- 54:36even before the COVID pandemic.
- 54:38And of course the physicality
- 54:39of being able to meet people and
- 54:41support them as being a major issue.
- 54:43As you know and so we've had that
- 54:46same sort of sobering effect
- 54:48and dampening effect on such
- 54:50separate programs and mechanisms.
- 54:53Right, it's difficult.
- 54:54I'm gonna start reading some questions
- 54:56that are coming in from the chat one.
- 54:58We just move up from Clara Yagi,
- 55:00a wonderful talk.
- 55:01How about instead of a C PAP for all
- 55:04approach where half donate here and
- 55:06become disenfranchised from care?
- 55:08Seems that we like to be heading to.
- 55:10It seems we need to be heading
- 55:12to more of a precision medicine
- 55:14approach up front with multiple
- 55:16modalities targeted to an individual
- 55:18patient preference and Physiology.
- 55:19Your thoughts?
- 55:20I'm 100% in support of that.
- 55:23Uhm, I I just, uh, you know,
- 55:26as both the researcher and as a clinician,
- 55:28I want guidance.
- 55:30And I want also help with
- 55:33operationalizing the guidance right?
- 55:36I mean, we got 40 minutes for new patient,
- 55:3820 minutes for return. Patient.
- 55:39Sorry I'm sort of bashing
- 55:41our bean counters here.
- 55:42Which hey, you know,
- 55:42hopefully they're not on the talk.
- 55:44They don't get on these talks
- 55:45because they're counting the beans,
- 55:47and so all I'm saying is just that
- 55:51I am totally in agreement with that.
- 55:53Approach, I just need guidance
- 55:55that I can actually easily
- 55:57implement in my clinical practice.
- 56:00That's the ask.
- 56:01Thank you, Karen Johnson has a question.
- 56:04You know the unmap expert panel
- 56:05had a lot of discussion over
- 56:07what Medicare should be asked to
- 56:09cover for not appear in patients
- 56:10as well as weather follow up.
- 56:12Visits are needed to keep the device.
- 56:14If a patient is adherent,
- 56:15what specific ask would you have
- 56:17for CMS or Congress in terms of
- 56:19how to cover devices and supplies?
- 56:23I really think they need to cash,
- 56:25so there are two separate things.
- 56:27One is device and suppliers right?
- 56:29And so the they need to make
- 56:31this 90 day rule go away.
- 56:34I honestly that's what I think
- 56:35and I think it should be based on
- 56:38whether someone has intent to use it.
- 56:40If someone has an intent to use
- 56:42they should be allowed to use it.
- 56:43And it's not like withholding
- 56:44insulin from a diabetic was emo.
- 56:46Globin A1C is 9.
- 56:47I mean, that's ridiculous,
- 56:49and so that's one supplies.
- 56:53Uhm, you know I actually, I got called
- 56:55by the office of Inspector General.
- 56:57You know while ago because the red
- 56:59one of our papers on resupply rates,
- 57:00which I didn't share today,
- 57:02and because they wanted an opinion,
- 57:03I thought I was in trouble,
- 57:04but they said no no.
- 57:07Like no, no,
- 57:07we want your opinion because we're trying to,
- 57:09you know, audits EMS.
- 57:10I mean DHS as to how they are doing
- 57:13the supplies and I think they
- 57:14also talked to petrol and couple
- 57:17other people and so you know,
- 57:18as they initially of course
- 57:19it was a little taken aback.
- 57:21But you know where the supplies.
- 57:23I really think we need to do a
- 57:25better job giving supplies up front.
- 57:27You know what they have is a
- 57:30prescriptive oh every three months.
- 57:32But we all know that in the first
- 57:3490 days they probably need more.
- 57:36They need exposure to.
- 57:37More devices and then they can paper it
- 57:39out and so when we looked at a hearing,
- 57:41people and an Indian people we
- 57:42could see the refund rate threshold
- 57:44which was something like .75
- 57:47masks and accessories in a one
- 57:50year period and that's the that's
- 57:53what enduring people are using.
- 57:55But in the first three months
- 57:57they want four machine,
- 57:59four mass so that it can find
- 58:01the message works for them.
- 58:02So I think you know they're going with
- 58:04a cookie cutter approach rather than
- 58:06a tailored approach, and I think.
- 58:07We need to go with a tailored approach
- 58:09where they get 5 masks in the first 90 days.
- 58:12I don't know maximum and then you
- 58:14can taper down to you know one mask
- 58:16every six months rather than one mask
- 58:18every three months during the entire life.
- 58:21I think that sounds fabulous.
- 58:22I think. I think you're
- 58:23definitely onto something there.
- 58:25I think we have time for one more question.
- 58:26Andres in check.
- 58:28Also, thanks for a wonderful talk.
- 58:30He said. What utility did you
- 58:32find in having summary adherence
- 58:35data for your sleep center?
- 58:36Did it lead to changes in
- 58:38practice or new interventions?
- 58:41First of all, it meets our SGM
- 58:43requirement for someone to do
- 58:45a quality improvement project.
- 58:46It's a low hanging fruit.
- 58:48I'm just sharing that with you,
- 58:49so they're not struggling so that then
- 58:50they can focus on their research project.
- 58:52And as you know, with these software,
- 58:54you can actually do an output
- 58:55of an Excel file.
- 58:57That's all I ask him to do.
- 58:58Hey, go click the output button
- 58:59generated and tell me how many
- 59:01people right here in an Indian.
- 59:02Now you tell me you create a white
- 59:04paper on your Qi because you already
- 59:06done that in literally 5 minutes.
- 59:08You've done your QR project.
- 59:10I want you write a white paper.
- 59:11And what you gonna do to
- 59:12help improve adherence?
- 59:13And that's where I get all my
- 59:15ideas to do sleep over there,
- 59:16see studies and sorry the second
- 59:18part of the question was what,
- 59:20again,
- 59:21whether this led to changes in
- 59:23practice or new interventions.
- 59:25Yeah, it did.
- 59:26And that's where we get our ideas.
- 59:28It led to changes in practice.
- 59:31For example, one of them decided
- 59:33to do it selectively on people who
- 59:35recently hospital discharge and
- 59:37and he hasn't written a paper, but.
- 59:41You know, showing how the people are
- 59:43adherents with their device after hospital
- 59:45discharge you know these are people.
- 59:47Comma, dislike CPU,
- 59:48basically hyperinflation syndrome or
- 59:50failure or less likely to get re-admitted.
- 59:53Then we were able to actually show
- 59:54that to our 30 hospital healthcare
- 59:56system spanning five States and
- 59:58we actually have a working group
- 01:00:00about how we can actually promote
- 01:00:02have therapy be at an Ivy or C PAP
- 01:00:05for patients with comorbid CPD to
- 01:00:08help reduce re hospitalization.
- 01:00:10And of course we've tried.
- 01:00:11Getting funding from NIH DoD Bakery and
- 01:00:14you know, that's not just me, you know,
- 01:00:17Jerry Trainer and they kill myself.
- 01:00:19We've tried it so many times and failed,
- 01:00:22but now we want to try and do
- 01:00:24maybe something in the realm of
- 01:00:26implementation science, but that's what.
- 01:00:27Led to that idea.
- 01:00:29So these Qi projects,
- 01:00:30by being able to do that.
- 01:00:31Looking at the dashboard is a is a good
- 01:00:34way for us to improve our outcomes.
- 01:00:37I mean, thank you. I think we are.
- 01:00:39We are at time right now,
- 01:00:40but this has really been
- 01:00:41just such an informative and
- 01:00:43and just interesting talks.
- 01:00:44So thank you so much for your time,
- 01:00:46really appreciate it.
- 01:00:47Thank you so much.
- 01:00:48Thanks for hiring me.
- 01:00:49I'm good to see all of
- 01:00:51those friendly faces there.
- 01:00:52Yeah bye bye bye bye now.
- 01:00:54Thank you bye.
