Abstract
Background
The homeless population is aging, with early onset of cognitive and functional impairments. It is unclear whether older homeless adults receive caregiving assistance that could prevent long-term disability.
Objective
We describe characteristics of older homeless-experienced adults with caregiving need and determine factors associated with having unmet need.
Design and Participants
Cross-sectional analysis of a longitudinal study, Health Outcomes in People Experiencing Homelessness in Older Middle Age (HOPE HOME), examining health, life course events, and functional status among older homeless-experienced (i.e., currently and recently homeless) adults. We recruited 350 homeless adults (July 2013–June 2014) and an additional 100 (August 2017 to July 2018) in Oakland, California; this study includes 303 participants who completed caregiving interviews.
Measurements
We defined caregiving need as difficulty with activities of daily living (ADLs), instrumental activities of daily living (IADLs), falls, Short Physical Performance Battery (SPPB) score < 10, or Modified Mini-Mental State (3MS) exam impairment. We defined unmet need as having caregiving need and reporting not receiving caregiving assistance in the last 6 months. Using logistic regression, we analyzed associations between respondent characteristics and unmet caregiving need.
Results
Among 303 participants, the mean age was 61.3 ± 5.0 years; 73% were men and 82% were Black. Eighty-one percent had caregiving needs, and in 82% of those, their caregiving needs were unmet. Better self-rated health (AOR 2.13, CI [1.02–4.46], p = 0.04) and being a man (AOR 2.30, CI [1.12–4.69], p = 0.02) were associated with higher odds of unmet need. Moderate or high-risk substance use (AOR 0.47, CI [0.23, 0.94], p = 0.03) was associated with lower odds of unmet need.
Conclusions
Older homeless-experienced adults have high prevalence of unmet caregiving need. 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.

INTRODUCTION
Adults over the age of 50 comprise a growing proportion of the individual adult homeless population.1 They have a high prevalence of geriatric conditions, including cognitive impairment, functional disability, and falls which indicate caregiving needs.2 Homeless-experienced (i.e., currently or formerly homeless) individuals experience geriatric conditions approximately 20 years earlier than the general population.2,3 High prevalence of co-existing mental health problems and substance use disorders further contributes to their vulnerabilities.4 Experiencing homelessness can have implications for disability and poor health outcomes even once individuals are housed.5,6
Homeless-experienced adults have difficulty accessing formal caregiving services, such as nursing or home health aide support.7 Home and Community Based Services (HBCS) provide opportunities for Medicaid recipients to receive services in their home or community rather than in institutions. HCBS accounts for over half of overall Medicaid long-term care spending but access to services is limited for individuals without a home.8 Homeless-experienced adults face barriers to informal caregiving (i.e., unpaid support from family or friends), due to disrupted social networks from frequent relocations, trauma, substance use, and mental health disorders.9 Homeless-experienced adults’ family and friends are often impoverished and struggle to provide care.9 Homeless-experienced individuals’ unmet caregiving needs may lead to disabilities that require costly long-term care.10
Caregivers, formal and informal, can meet these caregiving needs and decrease reliance on institutional care. Yet, there has been limited research examining the prevalence of caregiving need among homeless-experienced populations.11,12 Understanding the extent of these needs could allow for better assessment of their risk for disability and poor health outcomes.
In this study, we (1) describe the characteristics of older homeless-experienced adults with caregiving need and (2) determine sociodemographic and health factors associated with having unmet caregiving need.
METHODS
Study Overview
The Health Outcomes in People Experiencing Homelessness in Older Middle agE (HOPE HOME) study is a longitudinal study of health, life course events, and functional status among older adults who were homeless at study entry.13 The University of California, San Francisco Institutional Review Board approved all study activities.
Sample and Recruitment
In wave 1 of HOPE HOME, we used population-based sampling to recruit 350 homeless individuals age 50 and older in Oakland, California, from July 2013 to June 2014.13,14 We recruited participants from all overnight homeless shelters serving single adults over age 25 (n = 5), all low-cost meal programs serving at least three meals per week (n = 5), one recycling center, and places where unsheltered homeless individuals lived. We constructed our sampling frame to approximate the source population; we randomly selected potential participants at each recruitment site.13,15 In wave 2, we applied the same recruitment strategy to recruit 100 additional homeless individuals aged 53 and over from August 2017 to July 2018.
Participants completed study interviews every 6 months and remained in the study whether or not they regained housing. We analyzed data from the first interview for wave 2 participants and a concurrent follow-up interview for wave 1 participants. During this interview, wave 1 and wave 2 participants completed a caregiving questionnaire, which we introduced in 2017–2018 (Fig. 1).
Study Design and Population
To be eligible for HOPE HOME, participants had to meet age criteria, be homeless at study enrollment, be English speaking, and be able to give written informed consent using a teach-back method.16,17 We compensated participants $25 for the screening and enrollment interview, $5 for monthly check-ins, and $20 for follow-up interviews.
Measures
We collected participants’ sociodemographic characteristics including age, gender, race/ethnicity, marital/partner status, highest level of education, employment status, and income in the last 30 days.
Homeless and Housing Status
At each visit, we categorized participants as homeless versus not homeless, according to federal Homeless Emergency Assistance and Rapid Transition to Housing (HEARTH) Act criteria.16 We separately asked participants where they were currently staying and categorized responses as unsheltered, sheltered, in permanent housing for formerly homeless individuals, institution (i.e., skilled rehabilitation facility, nursing home, or sober living facility), transitional housing, hotel/motel, or apartment/house.
Social Support
We asked participants how many close friends or family members they had to confide in.18 We then categorized participants as having 0, 1–5, or ≥ 6 confidants.
Chronic Conditions
We categorized participants’ health as poor or fair versus good, very good, or excellent, based on self-report.19 We asked participants to self-report chronic medical conditions and grouped these as cardiovascular disease, pulmonary disease, chronic kidney disease, liver disease, diabetes, HIV/AIDS, and cancer. We categorized participants as having 0, 1–2, or ≥ 3 chronic conditions.
Substance Use and Mental Health
We categorized participants who reported consuming ≥ 6 drinks on one occasion monthly or more often as binge drinkers.20,21 To evaluate use of cocaine, amphetamines, or opioids, we administered the World Health Organization’s (WHO) Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST); we classified scores ≥ 4 as moderate- to high-risk use and 0–3 as low-risk use.22 Participants self-reported whether they were ever hospitalized for a mental health problem.
Caregiving Need
We asked participants, “What things did you get help with?” and allowed them to select multiple options from a list of 5 activities of daily living (ADLs—bathing, dressing, eating, transferring, or toileting) and 6 instrumental activities of daily living (IADLs, assessed using the Brief Instrumental Functioning Scale—managing medications, filling out applications for benefits, managing finances, using public transportation, setting up job interviews, finding an attorney).23,24 For each ADL and IADL, we asked participants whether they needed “no help,” “a little help,” “a lot of help,” or “someone to do it for me.” We classified participants as requiring any (“a lot of help” or “someone to do it for me”) or little to no (“a little help” or “no help”) assistance performing ≥ 1 ADL and ≥ 1 IADL.
Participants reported experiencing any falls in the past 6 months. We administered the Short Physical Performance Battery (SPPB) tool to assess lower extremity function and considered an SPPB score < 10 to indicate significantly limited lower extremity function.25
To assess cognitive function, we used the Modified Mini-Mental State Exam (3MS). We categorized 3MS scores below the 7th percentile as cognitive impairment.26,27
For our primary outcome, we defined caregiving need as experiencing any one of the following in the past 6 months: (1) difficulty with ≥ 1 ADL, (2) difficulty with ≥ 1 IADL, (3) ≥ 1 fall, (4) SPPB score < 10, or (5) 3MS score < 7th percentile. We developed our definition for caregiving need based on definitions used in nationally representative studies of older adults that examined caregiving need and functional limitations.28,29,30,31,32
Unmet Caregiving Need
We asked participants whether, in the last 6 months, anyone helped them with things like “bathing, dressing, eating, getting in and out of bed, using the toilet, moving around the house, getting to places outside the house, laundry, shopping or anything else.” We defined unmet caregiving need as meeting the definition for caregiving need but reporting not receiving caregiving assistance in the past 6 months. We adapted this definition from the National Health and Aging Trends Study (NHATS), which defines unmet need as an inability to perform a task due to the task being too difficult or not having assistance.33
Caregiving Characteristics
Participants reported characteristics of caregiving they received. We categorized participants’ relationship to their caregiver (i.e., partner, relative, friend), and whether their caregiver was paid or unpaid. For paid caregivers, we specified who paid them (In-Home Supportive Services [IHSS], Veteran Affairs [VA], other government program, insurance, family, or participant). We calculated the estimated hours of caregiving assistance received over the last month, by asking participants to estimate the number of days and hours per day during the last month their caregiver spent helping them. We specified the ADL and IADL tasks for which the caregiver helped.
When participants had multiple caregivers, we defined primary caregivers as those who provided the greatest number of hours of assistance over the last month; we described the characteristics of participants’ primary caregiver and caregiving situation.
Statistical Analysis
We used descriptive statistics to present participant sociodemographic and health characteristics, and to describe characteristics of caregiving received. Using chi-square and Student t tests, we compared characteristics of participants with and without unmet caregiving needs.
We restricted the sample to those with caregiving need and estimated multivariable logistic regression models examining the odds of having unmet caregiving. We included all independent variables with two-sided p values < 0.20 in the starting model and applied backwards elimination, retaining variables with two-sided p values < 0.05. We performed all statistical analysis using SAS version 9.4.
RESULTS
Participant Characteristics (n = 303)
Overall, 303 participants (203 from wave 1 and 100 from wave 2) completed the caregiving module (Fig. 1). The median age was 58 years; 73% were men and 82% were Black. Almost all (91%) were single or unpartnered; nearly one-quarter reported not having any confidants. Fifty-nine percent of participants were currently homeless. Seventy-three percent reported having chronic conditions, most frequently cardiovascular diseases (73%) and arthritis (53%); 37% had moderate–high-risk illicit drug use and 10% were binge drinkers. Half of participants reported their health as fair or poor. Eighty-one percent (n = 245) of participants had caregiving need.
Characteristics of Participants with Caregiving Need (n = 245)
Of the 245 participants who had caregiving need, 55% had difficulty with ≥ 1 ADL and 39% with ≥ 1 IADL. One-third (32%) experienced a fall in the last 6 months, 71% had an SPPB score < 10, and 22% had 3MS impairment (Table 1). Eighty-two percent of those with caregiving need did not receive caregiving in the past 6 months.
Characteristics of Caregiving Received (n = 45)
Of the 45 participants who reported receiving caregiving, 28 participants received paid caregiving; the majority (n = 21) of caregivers received payment through IHSS (Table 2). Participants reported that their caregivers spent an average 73.2 (± 122.0) h per month caregiving. Participants received assistance with activities including bathing (n = 23), dressing (n = 26), and finding an attorney (n = 16) (Table 2).
Association of Participant Characteristics and Unmet Caregiving Need
In bivariate analyses, those with unmet caregiving need were more likely to be homeless (64% vs 44%, p = 0.02); current housing categories were associated with unmet need (p < 0.01). Participants who were single (57% vs 76%, p = 0.04) and had moderate- or high-risk substance use (35% vs 51%, p = 0.03) were less likely to have unmet need (Table 3). In multivariable models, reporting good, very good, or excellent health (AOR 2.13, CI [1.02–4.46], p = 0.04) and being a man (AOR 2.30, CI [1.12–4.69], p = 0.02) was associated with higher odds of unmet need. Having moderate- or high-risk substance use (AOR 0.47, CI [0.23–0.94], p = 0.03) was associated with lower odds of unmet need (Table 4).
DISCUSSION
In a cohort of older homeless-experienced adults, we found that 81% of participants had caregiving need but less than 20% of those with caregiving need received assistance. Given their high risk for institutional care, homeless-experienced adults can benefit from programs that support access to caregiving in the community. Such strategies could potentially delay or avoid institutional care.
In national surveys, approximately 5–20% of housed adults over age 65 reported difficulty with self-care and 10% had cognitive impairments.34,35 In our sample (median age 58 years), over half had difficulty with self-care and over 20% had cognitive impairment. In previous work, we found that homeless-experienced adults had similar patterns of decline and persistence in functional impairments as those in older adults in the general community, suggesting that our participants’ caregiving needs likely reflect those of older populations. This reinforces the need for interventions to reduce reliance on institutional care for homeless-experienced adults.36,37
In national studies, about 20% of older adults report having unmet caregiving needs compared to 82% of homeless-experienced older adults in our study with unmet caregiving needs.35,38,39 This fourfold difference in unmet caregiving need highlights gaps in policies and practices for access to caregiving services among homeless-experienced adults. Home and Community-Based Services (HCBS) are designed to decrease reliance on institutional care by providing individuals with services, including assistance with ADLs and IADLs, that keep them living safely in their homes and their communities.8 People experiencing homelessness often face significant barriers to receipt of Medicaid-funded caregiving support despite their need for these services. These barriers range from statutory barriers restricting care to sheltered individuals to practical barriers created by cumbersome application processes.
For example, unsheltered homeless individuals are ineligible for California’s In-Home Support Services (IHSS) program—the state’s largest Medicaid HCBS program serving over 640,000 residents. IHSS providers help with a range of services including personal care, paramedical tasks, and transportation to medical appointments.40 While many older homeless individuals may have functional limitations that require caregiving, they do not have an address of residence, which excludes them from receiving IHSS.41 The IHSS application process requires demonstrating Medi-Cal eligibility and having a health provider complete a Health Care Certification form.40 Enrolled individuals must hire, pay, and monitor their IHSS provider; this can be challenging for adults with cognitive impairment or behavioral problems. Providing navigators to assist throughout the application process, hiring, and supervising of caregivers may improve access and retention of potential IHSS recipients who are homeless.
Our findings suggest that formerly homeless older adults continue to face barriers to receiving IHSS even once housed, including navigating a complex application process and managing hired caregivers. It is possible that expansion of pilot efforts to proactively expand IHSS to permanent supportive housing by leveraging trained staff with experience equipping formerly homeless individuals with the skills to navigate these barriers could alleviate this disparity.42 Ensuring equitable access to caregiving services for homeless-experienced individuals requires addressing structural barriers.43
In California, approximately 72% of people experiencing homelessness are unsheltered.44 Homeless-experienced adults’ friends and family are likely to experience deep poverty and have low household incomes, making it difficult for their social networks to provide unpaid care.9 Individuals who stay in congregate shelters face additional barriers. Shelter staff do not offer formal caregiving services and shelter policies restrict visitors, such that paid or informal caregivers cannot enter to offer residents assistance. Lifting visitor restrictions for caregivers could allow access to care recipients in need.45 While homelessness was associated with lack of receipt of needed caregiving in bivariate models, it was not significant in adjusted models. Homelessness is a dynamic state. We found that those who regained housing remained at risk of unmet caregiving needs.
Among those with caregiving needs, we found that men were more likely to have unmet need. This finding is consistent with work showing that while men present with higher levels of need when compared to women, men are less likely to access home care services and more likely to be admitted to long-term care.46 Older men experiencing homelessness may be less likely to seek, and thus receive, care. Participants who rated their health as better were more likely to have unmet caregiving needs. It is possible that being in better health facilitates the ability to “get by” without assistance due to having fewer overall needs or better ability to navigate existing needs. Yet, there are significant risks to not receiving assistance with the impairments we examined. Impairments in ADLs and IADLs are significant contributors to overall frailty and predictors of long-term disability.47,48,49 Homeless-experienced adults with caregiving needs who go without assistance may be at high risk for disabilities that lead to long-term care.
With the passage of the Affordable Care Act, more individuals now qualify for Medicaid, which could lead to a substantial increase in spending on institutional care among people experiencing homelessness.50 Given that the average per person annual costs of skilled nursing facility and long-term facility care are as high as $50,000 to $100,000, there is a need to develop strategies to reduce this potential spending.10 Community-based programs supported through Medicaid range from $5000 to $12,000 per individual in estimated average costs per year, one-fifth to one-tenth the cost spent on long-term care.51 Expanding such programs can increase access to caregiving and offer care recipients benefits, including maintaining autonomy and social connections.
Many community-based caregiving programs are not structured to accommodate homeless individuals. Recognizing the need for increased access to and funding for HCBS, the Biden administration’s American Rescue Plan Act included a significant temporary increase in federal funding for HCBS.52,53 This increased spending requires states to enhance, expand, and strengthen Medicaid-funded HCBS.54 In light of the growing aging homeless population, states should address structural barriers that homeless individuals face in accessing these programs.
Our study has limitations. Given the lack of prior work examining caregiving in homeless-experienced populations, we developed and applied a definition for caregiving need. This definition may have resulted in an over- or underestimation of caregiving needs. However, characteristics included in our caregiving need definition were drawn from prior research and are widely cited as contributors to caregiving need in nationally representative samples of older populations.28,29,30,31,32 Some participants may not have considered all potential sources of caregiving support when we asked whether they received assistance, potentially leading to an overestimation of unmet need. Individuals with the same level of disability, depending on their culture, age, and gender, can respond differently to instruments used to measure functional status.55 To minimize this potential bias, we administered an IADL tool developed for use in homeless populations.24 Some of our sample characteristics, including participant rates of current homelessness and institutional residence, are reflective of nationally representative data on homeless populations.56 However, we recruited participants from California, which may restrict the generalizability of our findings with respect to access to caregiving services. For example, California is one of few states that allow IHSS recipients to hire family members as caregivers, which may facilitate access to additional caregiving options for housed individuals.
This is the first study to describe caregiving need among older homeless-experienced adults and examine factors contributing to their unmet need. The high prevalence of unmet need in this vulnerable population has implications for individual health outcomes and future health system expenditures. By tailoring existing community caregiving resources to accommodate the needs of homeless-experienced older adults, we may better address their care needs while avoiding adverse and costly outcomes.
