Overview
The proposed study will use mixed methods research to examine overdose and other health-related impacts of harm reduction initiatives in NYC homeless shelters.
Description
Mixed-methods study using analyses of administrative homeless services and Medicaid data (Aims 1a, 1b, and 2) and in-depth qualitative interviews (Aim 3). This study will examine the implementation and impact of a Harm Reduction Strategic Plan (HRSP) portfolio of interventions in the NYC single-adult shelter system. The study will be conducted using administrative data (Aims 1a, 1b, and 2) and in-depth interviews and focus groups about client and staff experiences with the HRSP.

The matched comparison group will be comprised of individuals age 18 and older with active Medicaid coverage at the time of observation.

Exclusion Criteria:
Aims 1a, 1b, and 2: Children under age 18 years of age will be excluded.
Aim 3: Under age 18 years old, currently a prisoner (we are not sampling from locations where we expect to encounter prisoners), unable to communicate in English (because the interview and focus group guides will not be validated for use in other languages), and unable to provide informed consent.
For Aim 3 Homeless Services Client participant group: those who are not staying or have not stayed at a shelter with HRSP interventions and those who do not report past-year drug use will not be excluded.
For Aim 3 Homeless Services Staff participant group: those who have not been employed in a shelter with the HRSP interventions will be excluded. In alignment with standard techniques of purposeful sampling and the study goal of ensuring a range of experiences is captured in the qualitative interviews, additional targeting or exclusion criteria might be set by investigators as needed to ensure that a diverse range of experiences is included among qualitative interview participants.
