Drug overdose has increased in the U.S. since the COVID-19 pandemic began in 2020. In San Francisco, single-room occupancy (SRO) tenants are more likely to dive of opioid overdose than non-SRO residents. The SRO project aimed to reduce fatal overdoses in SROs. In this eight month ethnographic field work, researchers found that the SRO project increased awareness, access to, and understanding of naloxone, as well as, supporting the privacy and autonomy of tenants regarding their drug use.

Older adults experiencing chronic homelessness have low rates of advance care planning despite high rates of morbidity and mortality. Researchers explored if rehousing people who experience homelessness into permanent supportive housing (PSH) would present an opportunity to introduce advance care planning (ACP). Researchers identified behavioral determinants related to ACP for formerly chronically homeless adults in PSH.

Programs have been created to address housing for Veterans. However, Veterans are still at high risk for unstable housing. This study aimed to determine whether interpersonal violence was associated with unstable housing among Veterans. Research from BHHI demonstrated the potential to improve health outcomes through trauma informed approaches that address mental health, substance use, and housing concurrently.

People who use drugs (PWUD) commonly experience housing instability due to intersecting structural vulnerabilities. Researchers conducted a qualitative study in Vancouver, Canada's downtown eastside, interviewing PWUD who were recently evicted fron the downtown eastside. Narratives from the interviewees provided context on how the demands of the institutional circuit deepened vulnerablitities and prolonged experiences in homelessness. Researchers suggested that interventions that address survival needs and preserve agency will be necessary to mitigate risks within the institutional circuit.

People who inject drugs (PWID) experience housing instability and other structural barriers, making it hard for PWID to complete direct-acting antiviral (DAA) treatment of Hepatitis C. Researchers found that simple, low-cost medical storage containers, can be incorporated as a key component of a medication management plan. It is important to create a non-judgemental approach to providing HCV care.

Little is known how older adults with a current or recent experience of homelessness navigated the switch to telehealth during the COVID-19 pandemic. Researchers examined the perceptions and use of telehealth, sampling from a larger longitudinal study on homeless-experienced adults in Oakland, CA. They found that the participants experienced challenges accessing the necessary technologies for telehealth.

Margot Kushel, MD, director of UCSF’s Benioff Housing and Homelessness Initiative, wrote an editorial in JAMA about a recent study on the negative health consequences of involuntary displacements on the lives of people experiencing homelessness. Dr. Kushel writes, "The question is not whether living in unsheltered settings is dangerous, but rather what is the role of forced displacements in addressing the harm caused by them."

Alcohol use disorders (AUDs) are common among those experiencing homelessness. Managed alcohol programs (MAPs) are an evidence-based solution for helping people with AUD experiencing homelessness. Researchers examined and evaluated MAPs in Canada and California. They found that MAPs have successes and stabilization effects.

This study from BHHI researchers describes five distinct subgroups of the highest users of the health care system in San Francisco with differential comorbidities, health care needs, and social determinants of health, spanning from patients with medical comorbidities solely using medical services to patients grappling with housing insecurity, incarceration, substance use disorder, and mental health comorbidities. Frequent users of the health care system are not a homogenous population as previously thought. This study sheds new light on how to help the most vulnerable patients and inform clinicians and care coordination teams on making sure patients get the care they need the most. 

Patients with prolonged hospitalizations often require alternative levels of care (ALC) and there stays strain hospital capacity and patient flow. This study aimed to descriptively compare prolonged ALC and short ALC. Researchers found that patients with prolonged ALC were more likely to be older and have experienced homelessness. Furthermore, prolonged ALC patients were more likely to be admitted for acute care and had greater psychosocial complexity.

Over 70% of people experiencing homelessness report current tobacco use, compared to 14% in the general population. One of the structural barriers that hinder cessation attempts among people experiencing homelessness is inadequate access to health care and other smoking cessation services. Researchers in this study aimed to explore tobacco use behaviors and factors influencing acceptability of engaging in a clinical trials. Researchers found that participants had attempted to quit smoking, and were interested in engaging in clinical trials as a method to quit smoking.
