During the COVID-19 pandemic there was a 50% increase in opioid overdose deaths in the Shelter in Place (SIP) hotels for individuals experiencing homelessness in San Francisco. Community Behavioral Health Services Pharmacy partnered with SIP hotel medical staff to launch a pilot project where on-site SIP medical providers prescribed buprenor-phine (BUP) and clinical pharmacists hand-delivered BUP to SIP residents to increase BUP initiation and engagement. Researcher’s findings suggest that this system of onsite medical care with pharmacist delivery is possible and could allow for more outreach and increased ease of obtaining medications for patients.

Formerly chronically homeless adults who live in permanent supportive housing (PSH) have a high prevalence of smoking. Smoke-free policies and smoking cessation services are among the most effective tobacco control interventions, but these policies are uncommon in PSH. Researchers outline a protocol for a cluster-randomized wait-list controlled trial to evaluate the efficacy of the same smoke-free home intervention on the primary outcome of voluntary adoption of a smoke-free home.

Homeless street sweeps, where governmental agencies move unhoused individuals living in public areas, frequently occur in the US. In this qualitative study, researchers investigated and documented the health impacts on street sweeps from the perspective of healthcare providers. Researchers found that street sweeps negatively impacted health; there was material loss as well as instability and loss to follow-up.

In this cohort study, UCSF BHHI researchers found that most older homeless-experienced adults needed caregiving assistance and few received such assistance. Interventions that increase caregiving access for homeless-experienced individuals may help avoid poor health outcomes and costly long-term care needs due to untreated disabilities.

High users of the health care system use a disproportionate amount of health services yet have poorer health outcomes. This study aimed to examine natural trends in emergency department visits among high users of health and social services and assess whether the trends differed during the COVID-19 pandemic. In this retrospective cohort study, researchers found that there was a decrease in emergency department visits. Further research is needed to elucidate COVID-19 pandemic specific factors associated with a decrease in emergency department visits.

People living with HIV experiencing homelessness are more likely to have higher viral loads. The POP-UP model at the Ward 86 HIV clinic in San Francisco was designed to address barriers to care engagement. Researchers found an improvement in the 12-month HIV viral suppression from 0% to 44%. However, many patients were not virally suppressed. Researchers suggest that POP-UP clinics are promising to improve care engagement and HIV viral suppression among people experiencing homelessness.

In this long-term study of 450 homeless adults age 50 and older, BHHI researchers examined how factors like regaining housing, using drugs, and having various chronic conditions, such as diabetes, affected participants' risk of dying. They found that 26% of the participants died within a few years of being enrolled, and people who first became homeless at age 50 or older were about 60% more likely to die than those who had become homeless earlier in life, and those who remained homeless were about 80% more likely to die than those who were able to return to housing. These findings illustrate an urgent need for policy approaches to prevent and end homelessness among older adults in the United States and suggest that addressing older adults’ barriers to health care and high rates of institutionalization may prevent premature mortality.

Patients who experience homelessness face a high burden on chronic disease, including colorectal cancer. There are many barriers in access to colonoscopy procedures. Researchers provide policy solutions to reduce health care disparity.

People living with HIV/AIDS (PLWHA) have an increased risk of experiencing homelessness. The underlying drivers of homelessness are structural, however individual factors such as mental health and substance use problems are also common drivers. People living with HIV/AIDS who experience homelessness are more likely to have uncontrolled viral load. Researchers from BHHI suggest integrating HIV treatment with mental health and substance use treatment.

Housing status is a significant upstream determinant of access to healthcare. In this literature review, researchers identified areas of concern unique to patients experiencing homelessness with surgical disease. Researchers found that there was a gap in the surgical literature with regards to the impact of housing status on optimal surgical care. More studies are needed to accurately characterize the surgical care of patients experiencing homelessness and identify areas for care improvement.

Managed alcohol program (MAPs) manage alcohol consumption by providing eligible individuals with regular doses of alcohol as a part of a structured program and often offer housing and other social services. UCSF BHHI researchers found that benefits of MAPs included improved quality of life, reduced alcohol consumption, less hazardous consumption, and potential stabilizations in biological markers of alcohol use during MAP participation. Researchers found MAP participants reported substantial benefits, including increased feelings of safety and security, reconnection with community, sense of belonging, improved self-efficacy, and a positive reconciliation of internalized shame and stigma.
