Research Summary

Pulmonary embolism occurs when a clot blocks an artery that takes blood from the right side of the heart to the lungs. The condition is potentially life threatening. Finding methods to identify patients at greatest risk of harm (i.e. risk stratifying) from pulmonary embolism is important. Identifying patients at risk for harm allows us to offer aggressive interventions that may save lives. Comparing the effectiveness of various interventions will allow physicians to determine the optimal treatment for patients of all severities.

ICU patients are among the sickest in the hospital. They often have a long and complex hospital course. Studying the process and outcomes of these patients provides incites into the care they receive. Outcomes of interest include mortality, morbidity, length of stay and infections. Once information is gathered regarding the process and outcomes, interventions can be studied with the aims of improving outcomes for ICU patients in general.

Extensive Research Description

- Site Primary Investigator for the MARINER trial which is a multi-center trial that seeks to determine the ability of an oral anti-coagulant to prevent clots in recently discharged medical patients.

- Initiation of Pulmonary Embolism Response Team (PERT) and the accompanying data base that will allow us to analyze the safety and efficacy of interventions used to treat patients with pulmonary embolus.

- Sub-investigator in BEAT trial (pharmacological management of Pulmonary Arterial Hypertension) and MERCURY (outpatient management of low risk pulmonary embolism).
