The number of individuals incarcerated in the United States has increased since the 1970s. Frequent emergency department (ED) use and incarceration can both be driven by underlying structural factors and social needs. Researchers conducted a retrospective, cross-sectional analysis to assess whether an increased frequency of ED use was associated with incarceration. They found that ED use is independently associated with incarceration.

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.

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 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.

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.
