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.

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."

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.

Long-acting injectable antiretroviral therapy (LAI-ART) is approved for treatment-naive or experienced people with human immunodeficiency virus (HIV; PWH). The researchers performed the first LAI-ART demonstration project to include PWH unable to achieve or maintain viral suppression due to challenges adhering to oral ART at San Francisco's Ward 86. Researchers found preliminary short-term effectiveness of the treatment. More data on LAI-ART in hard-to-reach populations are needed.

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.

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.

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.

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.
