Figures from the 2024 CORE Report
Opioid Overdose Death Rate, Connecticut, 2017
In data from Connecticut, individuals receiving OUD treatment with either methadone or buprenorphine reduced their risk of fatal overdose compared to those not receiving any addiction treatment (39% reduction with methadone, 34% reduction with buprenorphine). These results are consistent with analyses in other states, other countries, and within high-risk subpopulations.

Unduplicated Recipients of Medications for Opioid Use Disorder (Methadone or Buprenorphine) in the State of Connecticut, 2012-2021
The number of individuals receiving methadone increased in the state substantially between 2012 (14,000) and 2017 (21,000), but there have been minimal increases since that time. (Figure 2) Similarly, the estimated number of individuals receiving buprenorphine increased in the state substantially between 2015 (21,000) and 2020 (30,000), with only modest increases since that time. There is less data on the proportion of people who are retained on either methadone or buprenorphine long-term. There are no reliable estimates of the number of people in the state at risk for overdose who would benefit from treatment with MOUD. Nonetheless, the rising number of opioid overdoses indicates there is an unmet need for these treatments in the state.
Source: Methadone treatment data displayed in this figure is sourced from the ADPC 2022 Substance Use Triennial Report and Hsiu-Ju Lin, PhD (DMHAS, University of Connecticut School of Social Work). Buprenorphine treatment data reflects an estimate based on DEA Automated Reports and Consolidated Orders (ARCOS) reporting of buprenorphine shipments to the state. Some percentage of unduplicated recipients of buprenorphine may reflect diagnoses or applications other than OUD (e.g., pain management).
Access as Measured by Travel Time, Driving (a) or Mass Transit (b), to At Least One Opioid Treatment Program in the State of Connecticut
These maps reflect an analysis of transportation access to opioid treatment programs (OTPs) in the state. This analysis estimates both the average weekday morning car-based and the mass transit (bus or train) travel time to at least one OTP from all points in the state. The gradations in color (yellow-to-red) represent cut-offs for travel time (i.e., 0-15 mins, 15-30 mins, etc.). In the map representing mass transit travel times, the bulk of the state is represented in gray, which reflects locations in the state that do not have ready access to mass transit. There are markers for each OTP in the state (blue mark) and overdose deaths (black dots) in the state. The overdose deaths have been geo-masked to obscure the actual location of the fatality. To account for density of unmet need for methadone treatment, we also estimated the average car-based and mass-transit based travel time from the location of all 1,018 opioid-involved overdose fatalities that occurred in 2019 to at least one OTP. This analysis demonstrated relatively good car-based access to OTPs, with the average travel time from the location of an overdose fatality to at least one OTP being 9 minutes and the vast majority of overdose locations (83%) being less than 15 minutes from an OTP. Mass-transit based access was much worse. The average mass-transit travel time to at least one OTP was 75 minutes and OTPs were inaccessible by mass-transit (no mass transit options at all) from one quarter of locations. Among locations with any mass-transit access, the majority (71%) were over 30 minutes of travel time by mass transit away from at least one OTP.

Partial Opioid Agonist Rate Per 1,000 Connecticut Residents, Quarter 3, 2023
The best estimates of geographic variation in buprenorphine prescribing in Connecticut come from yearly data from the Drug Enforcement Agency (DEA) reporting system on shipments of buprenorphine42 and publicly reported data from the DCP from the Connecticut Prescription Monitoring and Reporting System (CPMRS), otherwise known as the Connecticut Prescription Drug Monitoring Program (PDMP). Analysis of the DEA data found that shipments of buprenorphine to the state increased throughout the state from 2016 to 2022, but increases were unevenly distributed. Zip codes in the greater New Haven area and those in the eastern part of the state around New London and Norwich receive more buprenorphine per capita than other regions of the state. There have also been larger year-over-year increases in shipments of buprenorphine to the New London/Norwich area than in any other part of the state. This variation is reflected in publicly reported PDMP data from the DCP. These data demonstrate higher per capita buprenorphine prescription rates in the eastern part of the state, but also highlight towns in Litchfield County with similarly high per capita buprenorphine prescription rates. Data from the DEA and DCP should be interpreted with the understanding that buprenorphine can also be prescribed for the treatment of pain. We cannot distinguish in these datasets between receipt of buprenorphine for the treatment of OUD versus pain.
