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.

Cancer is the leading cause of mortality for people experiencing homelessness (PEH). However, not much is known about cancer-related surgical outcomes among PEH. This retrospective cohort study aimed to characterize access to care among PEH, evaluate postoperative outcomes, and assess costs associated with surgery for malignancy among PEH. Researchers found that PEH were less likely to undergo surgery for malignancy at cancer centers than hose who are housed. People experiencing homelessness also had a higher risk of requiring unplanned surgery.

Unhoused patients have worse outcomes and higher health care utilization compared to their housed counterparts. Previous research has primarily focused on physical and behavioral health. This retrospective cohort study investigated the association between housing status and the nature of surgical care provided, health care utilization, and operational outcomes. Researchers found that unhoused patients commonly underwent emergent operations and had more complex hospitalizations.

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.

 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.

Little is known how older adults with a current or recent experience of homelessness navigated the switch to telehealth during the COVID-19 pandemic. Researchers examined the perceptions and use of telehealth, sampling from a larger longitudinal study on homeless-experienced adults in Oakland, CA. They found that the participants experienced challenges accessing the necessary technologies for telehealth.

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.

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 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.

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.

In this long-term study of 450 homeless adults age 50 and older, BHHI researchers examined how factors like regaining housing, using drugs, and having various chronic conditions, such as diabetes, affected participants' risk of dying. They found that 26% of the participants died within a few years of being enrolled, and people who first became homeless at age 50 or older were about 60% more likely to die than those who had become homeless earlier in life, and those who remained homeless were about 80% more likely to die than those who were able to return to housing. These findings illustrate an urgent need for policy approaches to prevent and end homelessness among older adults in the United States and suggest that addressing older adults’ barriers to health care and high rates of institutionalization may prevent premature mortality.

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 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.

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.
