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.

A study from UCSF Benioff Homelessness and Housing Initiative examined implementation of a rapid COVID-19 test and response model in congregate shelters in San Francisco. The pilot allowed for detection and isolation of cases among staff and residents. Researchers recommend frequent testing with rapid turnaround as an important public health intervention to improve accessibility and availability of testing, identification, and isolation of COVID-19 positive cases in shelters.

Unstable housing has been associated with a higher risk of kidney disease and kidney disease progression. In this review, researchers discussed the underlying mechanisms of housing and kidney disease. Several considerations should be taken into account when working with individuals experiencing unstable housing or at risk for kidney disease. This review sheds light on that housing interventions can improve outcomes.

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.

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.

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.

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.

The COVID-19 pandemic disrupted economic systems, social networks, and individual behaviors, altering patterns in health care use. In this study, researchers compared homeless and unstably housed (HSH) women who did and did not use an emergency department during the first 10 months of the pandemic. The researchers found that the rate of emergency department use among HUH women during the pandemic was similar to prior research.

The homeless population is aging and people experiencing homelessness are at a heightened risk of experiencing physical and sexual victimization. This study examined whether homelessness is independently associated with experiencing physical or sexual abuse. Researchers found that older homeless adults experience high rates of victimization.
