In this retrospective observational cross-sectional study of patients in the Trauma Quality Improvement Program (TQIP), researchers looked to determine if there was significant practice variability in adoption of alcohol and drug screening of injured patients among hospitals participating in TQIP. Researchers found that overall rates of recommended alcohol and drug screening of injured patients were low and varied significantly between hospitals.

A new study from UCSF Benioff Homelessness and Housing Initiative and the San Francisco Department of Public Health describes how San Francisco rapidly scaled a hotel-based isolation and quarantine (I/Q) system of care for people experiencing homelessness during the COVID-19 pandemic. Researchers found the program safely delivered integrated medical and behavioral health support to more than 1000 individuals outside the hospital setting, while helping to preserve hospital capacity.

Hospital emergency departments (ED) are on the frontlines of serving people experiencing homelessness, and this report investigated what ED data can reveal about homelessness in California. Hospitals operated by counties and the University of California reported higher shares of ED visits by people experiencing homelessness. Linking discharge data with homeless services programs can offer insights into how people engage with programs and help provide better resources to evaluate the programs and investments aimed at improving the lives of Californians experiencing homelessness.

 Traumatic injury is a major cause of morbidity for people experiencing homelessness (PEH), however, injury patterns and subsequent hospitalization among PEH have not been studied on a national scale. In this national retrospective observational cohort study, researchers evaluated whether differences in mechanisms of injury exist between PEH and housed trauma patients in North America and whether the lack of housing is associated with increased adjusted odds of hospital admission. Researchers found that injured PEH had a significantly adjusted greater odds of hospital admissions.

Loneliness is often more common in older adults and those who face structural vulnerabilities, including those who experience homelessness. In the United States, 48% of single homeless adults are 50 and older. There is a limited information about loneliness among older adults who have experienced homelessness. This study used qualitative data collected as part of a longitudinal mixed-methods study, Health Outcomes of People Experiencing Homelessness in Older Middle Age (HOPE HOME). The study aimed to examine the intersection between social isolation, functional and cognitive impairment, and use of supportive services among a cohort of older adults experiencing homelessness in Oakland, California. Researchers found that homeless-experienced older adults with cognitive or functional impairments exhibited diverse loneliness experiences.

The median age of single homeless adults is approximately 50 years. Older homeless adults have poor social support and experience a high prevalence of chronic disease, depression, and substance use disorders. This study aimed to describe the access to and use of mobile phones, computers, and the Internet among a cohort of 350 homeless adults over the age of 50 years. Researchers found that participants with phones used them for social support and communication with healthcare providers; however, few had annual phone contracts.

A guest column by Margot Kushel, MD, director of the UCSF Benioff Homelessness and Housing Initiative, and Kevin Prindiville, JD, looks at the rise in homelessness among people older than 50: “With rising housing costs, fewer pensions, and a fraying safety net, many older adults are one crisis away from losing the roof over their head.”

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.

The homeless population in the United States is aging, however, there is limited studies on the neurologic etiologies of cognitive impairment in this population. Researchers observed a wide range of focal neurological deficits in the study participants, most notably deficits in cranial nerve function, motor function, coordination, and peripheral sensory functions. This study lays the foundation for the development of a longitudinal study of neurocognitive health among unhoused older adults in San Francisco.

The prevalence of tobacco use among populations experiencing homelessness is between 60% and 80%. In this qualitative study, researchers examined attitudes toward tobacco control policies among older African American homeless-experienced smokers. Researchers identified seven major themes from their in-depth semistructured interviews. They found that older African American homeless-experienced smokers face significant barriers to smoking cessation.

People experiencing homelessness have inadequate resources for regular dental hygiene and a higher prevalence of risk for tooth loss, including smoking and substance use. This study aimed to describe the prevalence of and factors associated with oral health measures in a sample of older homeless adults in Oakland, CA. Researchers conducted a cross-sectional analysis of data from a population-based study of 350 homeless adults aged ≥50. They found that tooth loss and oral pain are highly prevalent in older homeless adults.

Little is known about pathways to homelessness among older adults. In this study, researchers interviewed 350 homeless adults, aged 50 and older, recruited via population-based sampling. Participants reported current health and functional status, including recent mental health and substance use problems. Researchers found that the life course experiences and current health and functional status of individuals with first homelessness before age 50 differed in key ways from those whose first homelessness occurred later.

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.

Homeless adults in their 50s and 60s have a similar prevalence of geriatric conditions, including functional and cognitive impairment, as adults in their 70s and 80s in the general population. Researchers aimed to describe the prevalence of symptoms among older homeless-experienced adults, analyze factors associated with moderate–high physical symptom burden, and identify symptom clusters. They conducted a cross-sectional analysis within longitudinal cohort study. Researchers found a high prevalence of symptomatology across multiple domains. They found that symptom domains clustered together: those with higher physical symptomatology had a high prevalence of other symptom domains.

Over 2.5 million people experience homelessness yearly in the United States. Black persons are overrepresented by three-fold among those experiencing homelessness. Researchers aimed to understand the relationship between race and the experience of homelessness for older adults. They developed a theoretical model of the way experiences with overt and structural racism may lead to and perpetuate homelessness for older Black adults. Researchers recommend that efforts aimed at ending homelessness target the effects of structural racism with polices.

Adults aged 50 and older make up half of individuals experiencing homelessness and have high rates of morbidity and mortality. Researchers administered structured interviews including assessments of health, history of homelessness, social support, and life course. They found that compared to those who were unsheltered, having social support when last stably housed was significantly associated with cohabiting and institution use. Further research on the newly homeless individuals and cohabiters in this cohort may elucidate more clearly the trajectories of these different phenotypes of homelessness.

The proportion of single homeless adults over the age of 50 is increasing. In this longitudinal cohort study, researchers examined the prevalence of and risk of falling in a cohort of older homeless adults. Researchers interviewed participants every 6 months for 3 years. They found a high prevalence of falls. Participants reported a prevalence of falls higher than older adults with a mean age of 78 in the general population. Researchers recommended identifying people at high risk of falls reducing unsheltered homelessness.

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.

Sleep is essential to health and affected by environmental and clinical factors. There is limited longitudinal research examining sleep quality in homeless older adults. This exploratory study examined the factors associated with poor sleep quality in a cohort of older adults in Oakland, California. Researchers found that participants had higher prevalence of poor sleep and worse Pittsburgh Sleep Quality Index (PSQI) scores than in studies of housed adults 20 years older.

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.

Older homeless adults experience premature development of age-related conditions and an elevated symptom burden. The study aimed to characterize the experience, understanding, and management of physical, psychological, social (e.g., loneliness), and existential (e.g., regret, loss of dignity) symptoms among older homeless adults. Researchers conducted semistructured interviews from June 2016 to March 2017 with a purposive sample of participants from the Health Outcomes of People Experiencing Homelessness in Older Middle Age cohort, a longitudinal study of homeless adults aged 50 and older. They found that homelessness causes and exacerbates physical and psychological distress. Interventions should address multiple interconnected dimensions of suffering.

Tobacco-attributable deaths contribute significantly to the increased mortality observed among homeless adults aged 50 years or more. In this longitudinal cohort study, researchers examine smoking behaviors and factors associated with smoking cessation among homeless individuals aged 50 years or more. Researchers found tobacco use in older homeless adults and rates of quit attempts were similar to that observed in the general population, but successful quitting was lower.

Difficulty performing activities of daily living (“functional impairment”) is common in homeless adults aged 50 and older. Homeless adults develop aging-related conditions earlier than individuals in the general population, including difficulty with basic activities of daily living (ADLs) that are essential for independence. Researchers conducted a prospective cohort study to assess functional trajectories based on self-reported difficulty performing 5 activities of daily living. They found functional impairment improved in some homeless adults, it persisted or worsened in many others.

The San Francisco Department of Public Health implemented the Coordinated Care Management System (CCMS) in 2007. The CCMS is used to develop High Users of Multiple Systems (HUMS) tp identify individuals with the highest use of emergency medical services. Researchers described the HUMS scoring system and the characteristics and service use of the highest scoring 100 individuals. Researchers found that nearly all of the individuals had a history of homelessness in SF, and over half were unsheltered at their last point of contact.
