Neighborhoods, Mental Health, & Prevention of Opioid Overdose: A Mixed Methods Approach

K01 DA049900. NIH/NIDA. Role: PI

The broad objective of this study is to investigate modifiable neighborhood factors which impact mental health and which may contribute to opioid overdose risk. The study will use mixed quantitative/qualitative approaches with fatal overdose data from three major U.S. cities and original in-depth interviews with people who use drugs to achieve the following aims: (1) investigate the associations between modifiable physical and social neighborhood factors and opioid OD; (2) examine key mental health indicators as mediators of the relationship between modifiable neighborhood factors and opioid OD; (3) comparatively investigate the associations between modifiable neighborhood factors, mental health indicators, and opioid OD, comparing the locations where opioid users lived versus the locations where they overdosed.

Development of a Systematic Social Observation Tool for Monitoring Use of Harm Reduction Supplies

Penn Injury Science Center Pilot Grant Program, part of the Centers for Disease Control and Prevention (1R49CE003083). Role: MPI

The most common ways to monitor bystander naloxone use is when those who have received take-home naloxone (THN) return to a distribution point for a subsequent dose or when outreach teams who distribute naloxone ask individuals about recent ODs they have witnessed. However, reporting of witnessed ODs may be incomplete, and naloxone distribution programs often have difficulty tracking naloxone use. Consequently, harm reduction service providers need inexpensive, easy-to-use, evidence-based tools to assess community uptake of harm reduction supplies. The broad objective of this study is to develop a valid and reliable, standardized inventory of harm reduction supplies that can be used by community harm reduction organizations to monitor use of harm reduction supplies.

Alcohol and Pedestrian Injury: Inquiry into Built and Social Environment Factors

F31 AA023716. NIH/NIAAA. Role: PI/Trainee

The fellowship consisted of two complimentary components: (1) A research project examining the relationship between alcohol outlet density and pedestrian injury in Baltimore City, with an emphasis on the impact of both the built and social environment on pedestrian injury in areas of greater alcohol outlet density; (2) A comprehensive training plan composed of advanced coursework; mentorship in the content areas of alcohol epidemiology, systematic social observational, spatial analysis, and health disparities research; and dissemination of results through manuscripts and scientific presentations.
