The Health x Housing Lab at NYU Langone conducts research to build the evidence base for initiatives, programs, and policies at the intersection of health and housing. We are committed to improving the translation of research to practice and policy, meaningfully including people with lived experiences of homelessness and housing insecurity in research, providing opportunities for emerging leaders to contribute to and grow professionally in the field, and prioritizing the values of housing and health care as human rights.

Allied Care Coordination Initiative Evaluation

The Lab has undertaken a four-year (2025–2029) mixed‑methods evaluation of a pilot program implemented by NYC Health + Hospitals and homeless outreach providers. Lab Co-Director, Giselle Routhier, PhD, is co-principal investigator with Carolyn Berry, PhD, professor in the Department of Population Health. The evaluation will analyze program implementation, effectiveness, and cost impacts for individuals experiencing homelessness and serious mental illness. This evaluation is funded by The Leona M. and Harry B. Helmsley Charitable Trust.

Housing Choice Vouchers (HCV): HCV-Health & HCV-Kids

The Lab is partnering with the NYU Furman Center to conduct a four‑year mixed methods study (2025–2029) that will examine the impact of Housing Choice Vouchers (HCVs) on health and housing outcomes, as well as potential effects of health status on ability to successfully use the vouchers. Lab Co-Director, Kelly Doran, MD, is co-principal investigator along with Ingrid Gould Ellen, professor of Urban Policy and Planning at the NYU Wagner Graduate School of Public Service. This study is funded by the National Institute of Nursing Research. A second study funded by the CoLab at Constellation Fund will assess the effects of HCVs on educational and health outcomes for children.

Shelter Harm Reduction Evaluation (SHARE)

Lab Co-Director, Dr. Doran, and Bennett Allen, PhD, assistant professor of Epidemiology in the Department of Population Health’s Center for Opioid Epidemiology and Policy (COEP), are leading an evaluation of the harm reduction initiatives in NYC homeless shelters. The study will be conducted in partnership with the NYC Department of Homeless Services and the NYU Health Evaluation and Analytics Lab, and will use quantitative and qualitative research methods to examine the impact of innovative systemwide harm reduction efforts in NYC shelters on overdose and other key outcomes. This study is funded by the Centers for Disease Control and Prevention.

Improving Older Adults’ Transitions from Homelessness to Home (OATH) Study

In partnership with the Corporation for Supportive Housing, Care for the Homeless, and a core group of people with lived experience of homelessness as older adults, the Health x Housing Lab is conducting a qualitative study that will examine the housing, health, and social needs of older homeless adults (age 55+) and identify resources needed to better facilitate rapid transitions to housing for this population. The research will build capacity for community-engaged research at the intersection of health and housing that centers the voices of people with lived experience and leverages the collective strengths of academia, community-based organizations, people with lived experience, and government partners to identify and implement solutions to homelessness among older adults. The study (2023–26) is funded by the U.S. Department of Housing and Urban Development.

Permanent Supportive Housing Overdose Prevention (POP) Study

Focused attention on the social conditions affecting overdose is critically important to forestall deaths and reduce widening inequities. This study (2022–27) uses a stepped wedge cluster randomized controlled trial and qualitative interviews to examine the implementation of evidence-based practices to prevent overdose in permanent supportive housing—housing that serves formerly homeless individuals who face disproportionately high risk for overdose—in New York City and New York’s capital region. The study is being conducted in partnership with the Corporation for Supportive Housing. Findings will lay the groundwork for widespread implementation of overdose prevention practices in permanent supportive housing and inform similar implementation efforts for other housing settings that serve at-risk populations. This study is funded by the National Institute on Drug Abuse. The principal investigator is Dr. Doran.

COVID-19 Hotel Intervention for People Experiencing Homelessness (CHIP) Study

This study (2022–27) uses community-partnered, mixed-methods research to examine substance use and related health impacts of moving homeless individuals to hotel rooms, leveraging a policy change that occurred in response to the COVID-19 pandemic. The NYU Langone study team is working in partnership with the New York City Department of Social Services and Project Renewal Inc. The research will inform future local and national programmatic and policy interventions to address the intersecting issues of homelessness and substance use, which is especially important as homelessness has reached crisis levels and is predicted to rise further in the wake of the COVID-19 pandemic. This study is funded by the National Institute on Drug Abuse. The principal investigator is Dr. Doran.

Nurse Call Line Qualitative Evaluation

The Health x Housing Lab conducted a qualitative evaluation of a Nurse Call Line pilot program implemented in New York City Department of Homeless Services shelters. The Nurse Call Line pilot offered 24-hour access to a live nurse, who provided advice, connections to telehealth, and referrals to in-person care for residents with non-emergency medical conditions.

Our qualitative evaluation examined perceptions, experiences, and interactions with the Nurse Call Line, as well as barriers and facilitators to implementation. This evaluation (2022–23) was funded by the Helmsley Charitable Trust.

Cash Assistance Evaluation

In partnerships with NYC Health + Hospitals and Test & Trace, the Health x Housing Lab team evaluated a program implemented in response to the COVID-19 pandemic that provided one-time, unconditional cash transfers of $1,000 to low-income New Yorkers who contracted or were exposed to COVID-19.

Using a mixed-methods approach, we examined how program recipients used the $1,000 cash transfer, their experiences with the program, and self-reported effects of receiving the cash transfer on their health and social needs. This study (2021–22) was funded by the Robin Hood Foundation. Results of the study were published in Journal of Urban Health.
