California passed the Community Assistance, Recovery, and Empowerment (CARE) Act in 2022 to provide behavioral health and housing services to individuals with psychotic spectrum and schizophrenia disorders who are deemed unable to care for themselves. This policy brief from the Benioff Homelessness and Housing Initiative at UCSF and the California Policy Lab uses anonymized data to estimate how many San Franciscans in a database of individuals who have contact with the urgent and emergent care system may be eligible for referral to CARE Court and describe their service needs.

People experiencing homelessness (PEH) have a high rate of tobacco use. Researchers examined factors associated with cigarette consumption and quit attempts. They found having an encounter with staff in the past week was associated with a 40% reduction in weekly consumption. The findings highlight the role of community-based pharmacists to expand smoking cessation services in homeless shelters.

The homeless population is aging and adults who experience homelessness for the first time in older age are more likely to progress to chronic homelessness. To prevent or delay homelessness, many people live temporarily live with family or friends. In this qualitative study of homeless older adults, researchers conducted 46 semi-structured interviews. They found that structural barriers to family and friends providing housing for temporary or permanent exits from homelessness included housing regulations, geographic and transportation challenges, and environments inconducive to older adults.

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. 

In the United States there has been a simultaneous rise of mass incarceration and homelessness. Both of these phenomena are driven by the same structural factors, housing being the most important. Researchers present evidence-based approaches to improve housing strategies for reentry populations, prevent homelessness among those in community supervision, and rehouse members of the reentry community experiencing homelessness.

In this op-ed, Ryan Assaf, PhD, MPH, a postdoctoral fellow with the Benioff Homelessness and Housing Initiative, highlights the importance of using harm reduction strategies. He outlines the use and impact of needle exchange programs, reducing the transmission of viral infections and acting as a bridge to other services. Dr. Assaf further emphasizes that criminalizing drug use will not make the problem disappear. "These services create a space of trust where individuals who use drugs can seek help, referrals, and navigation to substance use treatment and counseling if and when they are ready for it." Dr. Assaf writes. This op-ed was published as part of the Public Voices Fellowship in partnership with The OpEd Project and funding from the California Health Care Foundation.

In this op-ed, Maya Vijayaraghavan, MD, MAS, director of the UCSF Smoking Cessation Leadership Center, highlights the need for widespread access to tobacco treatment among people experiencing homelessness and the structural issues underpinning tobacco use. She emphasizes that in the homelessness advocacy and provider community should not normalize tobacco use among people experiencing homelessness and there is increased awareness and trained staff in shelters to provide tobacco treatment. "Providing tobacco treatment will substantially reduce harm, save lives, and improve financial stability by supporting quitting." Dr. Vijayaraghavan writes. This op-ed was published as part of the Public Voices Fellowship in partnership with The OpEd Project and funding from the California Health Care Foundation.

About 70-80% of adults experiencing homelessness smoke cigarettes. Researchers examined guest support for on-property smoke-free policies within an homeless shelter amongst never smokers, former smokers, and current smokers. They found that 64% of participants supported a partial smoking ban, while 32% supported a full smoking ban. These findings illustrate that implementing smoke-free living/workplace policies in homeless shelters enjoys more support from guests.

In this cross-sectional study, researchers studied the association between residential relocation and health outcomes in people who inject drugs (PWID). PWID are at an increased risk of low socioeconomic status and homelessness. Researchers found that any residential movement in the past 30 days was associated with increased odds of bad health outcomes.

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.

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.

A record number of seniors are burdened by high housing costs. A new report from University's Joint Center for Housing Studies sounds the alarm as the US population ages rapidly. The number of seniors who will qualify for federal housing subsidies will continue to grow. The report also notes that more people over the age of 50 are losing housing for the first time. Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative, said, "Increasingly, the story of homelessness among adults is going to be older adults living in poverty, who are spending what should be their retirement years in the streets."

This UCSF study examined deaths among people experiencing homelessness in San Francisco from 2016 to 2018. Although heart disease and cancer are the first and second causes of death for California’s general population, the leading causes of homeless deaths were acute intoxication (unintended overdose) and trauma (including homicide and suicide rates over triple that of the US general population). The authors advocate that these differences in cause-specific mortality should inform death prevention efforts within the homeless population differently than the general population.

This study from UCSF BHHI researchers examined deaths among people experiencing homelessness in San Francisco during the first year of the COVID-19 pandemic. They found 82% of 331 deaths were associated with drug overdose, not COVID-19 infection. Traumatic injury, including homicide and suicide, was the second most common cause of death. This research highlights a need for strategies that address both homelessness and drug use, including housing, evidence-based treatment of opioid addiction, and overdose prevention programs.

Tobacco use is common in people who experience homelessness; however, research in homeless and unstably housed (HUH) women is sparse. Researchers found that the most common reason for tobacco use was to reduce stress and anxiety. The findings suggest that tailored counseling and healthcare interactions that include smoking cessation efforts and address food insecurity during treatment.

In the state of California, the three major utility companies, have nearly doubled electricity rates over the last decade. With growing increase in energy demands, the rising utility costs are pushing families already at the margins to the brink of homelessness. Many people are forced to making an impossible choice. Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative, said, "I think recognizing energy insecurity as a contributor to this crisis, this is the next frontier that we need to really worry about."

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.

People with multiple, complex health and housing needs frequently receive fragmented care because the providing systems operate independently. The California Policy Lab at UC Berkeley and the UCSF Benioff Homelessness and Housing Initiative worked with partners in San Francisco’s public health and criminal legal systems to link together ten years of data from the physical health, behavioral health, housing, and criminal legal sectors.

Following is a statement by Dr. Margot Kushel, MD, Director of the Benioff Homelessness and Housing Initiative (BHHI) at the University of California, San Francisco on the 2023 Annual Homeless Assessment Report, released today by the U.S. Department of Housing and Urban Development.

Recently the demographic characteristics of people experiencing individual homelessness have changed; more individuals over the age of 50 are experiencing homelessness. BHHI researchers examined the motivations for and challenges of older adults experiencing homelessness staying with or moving in with family or friends. Researchers found barriers to stay such as feelings of shame and concerns about burdening the hosts. Findings suggest that family members and friends may play an important role in supporting older adults experiencing homelessness.

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.

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.
