  • Onsite Primary Care to Address Medical Needs Among Permanent Supportive Housing Tenants: A Feasibility Demonstration Project

    by Brian Redline, John Nusser, Janae Brill, Patrick Brown, Sarah Ichiki, Brian Chan

    Background There is limited evidence on interventions to address the health needs of vulnerable patients in permanent supportive housing (PSH). Aim, Setting, Participants Evaluate the feasibility of Project HOPE, a weekly onsite primary care pilot intervention for tenants of a single-site PSH program. Program Description Physicians, nursing, and pharmacy providers work with existing case managers to provide onsite routine and acute care, outreach, and care coordination. Operations began in November 2020. Program Evaluation Chart review (n = 26) of electronic health records assessed primary care engagement during the 180 days pre- and post-implementation using paired t tests and McNemar’s exact tests, alongside formative observations from site visits and monthly meetings. Compared to the pre period, there was a 50% increase in the proportion of tenants with any primary care engagement (95% CI, 0.24, 0.76), and 84.6% of tenants had at least one visit with Project HOPE. Tenants averaged 2.65 more PCP visits during the post period compared to the pre period (95% CI, 1.60, 3.71). Housing staff perceived improvements in care continuity, chronic disease management, and access to care for tenants. Discussion An onsite primary care delivery model led to increases in primary care engagement for high-acuity PSH tenants.


  • Food insecurity, hunger, stress, and homelessness among young adults.

    by Eldin Dzubur, Sara Semborski, Brian Redline, Donald Hedeker, Genevieve F. Dunton, Benjamin F. Henwood

    Background: Compared to the effects of stress on hunger, the temporal effect of hunger on stress levels is less understood, especially in the context of everyday lives of vulnerable populations with unstable access to food. Objective: Our objective was to examine the effects of food insecurity and momentary hunger on momentary stress and stress variability in a sample of currently and formerly homeless young adults. Method: We used a 7-day ecological momentary assessment study querying affect, hunger, and risky behaviors. A mixed-effects location scale model was used to examine the effects of hunger on mean levels and within- and between-subjects variability of stress with 100 currently homeless and 69 formerly homeless young adults ages 18-29 in Los Angeles County, California. Results: When individuals experienced greater-than-average hunger, they then experienced greater stress variability at the next prompt, showing the impact of hunger on stress at the momentary level. Those with higher average levels of stress, regardless of hunger, became substantially more stressed when becoming hungry compared to their generally less stressed counterparts. Conclusions: The study shows the extent to which food insecurity results in erratic stress among vulnerable populations and how high levels of hunger may lead to a more inconsistent stress response. Findings reinforce the need for more mental health services and food programs for young adults who have experienced homelessness.

    Feasibility and Acceptability of Ecological Momentary Assessment With Young Adults Who Are Currently or Were Formerly Homeless: Mixed Methods Study

    by Sara Semborski, Benjamin Henwood, Brian Redline, Eldin Dzubur, Tyler Mason, Stephen Intille

    Background: Ecological momentary assessment (EMA) has been used with young people experiencing homelessness to gather information on contexts associated with homelessness and risk behavior in real time and has proven feasible in this population. However, the extent to which EMA may affect the attitudes or behaviors of young adults who are currently or were formerly homeless and are residing in supportive housing has not been well investigated. Objective: This study aims to describe the feedback regarding EMA study participation from young adults who are currently or were formerly homeless and examine the reactivity to EMA participation and compliance. Methods: This mixed methods study used cross-sectional data collected before and after EMA, intensive longitudinal data from a 7-day EMA prompting period, and focus groups of young adults who are currently or were formerly homeless in Los Angeles, California, between 2017 and 2019. Results: Qualitative data confirmed the quantitative findings. Differences in the experience of EMA between young adults who are currently or were formerly homeless were found to be related to stress or anxiety, interference with daily life, difficulty charging, behavior change, and honesty in responses. Anxiety and depression symptomatology decreased from before to after EMA; however, compliance was not significantly associated with this decrease. Conclusions: The results point to special considerations when administering EMA to young adults who are currently or were formerly homeless. EMA appears to be slightly more burdensome for young adults who are currently homeless than for those residing in supportive housing, which are nuances to consider in the study design. The lack of a relationship between study compliance and symptomatology suggests low levels of reactivity.

    The Effect of Momentary Affect on Substance Use among Young Adults Who Experience Homelessness

    by Sara Semborski, Danielle R. Madden, Eldin Dzubur, Brian Redline, Harmony Rhoades, Benjamin F. Henwood

    IntroductionLittle is known about the momentary patterns and predictors of substance use among young adults who experience homelessness. To enhance understanding of substance use patterns, smartphone-based ecological momentary assessment (EMA) was utilized to examine the real-time association between affect and substance use. Methods: 251 young adults (aged 18–27) with history of homelessness were recruited from supportive housing programs and drop-in facilities in Los Angeles. Exploratory factor analysis was used to examine the latent structure of positive and negative affective states and mixed-effects logistic regression models were completed separately for both the full remaining sample (n = 227) and a subsample of alcohol or cannabis users (n = 145) to evaluate whether positive or negative affect predicted lead, recent, or lagged substance use. Results: Greater positive affect within-person was associated with greater odds of alcohol or cannabis use within the past two hours, and participants who reported feeling more negative than their peers experienced greater odds of reporting use within the past 4 h and the following two hours. Conclusion: Results suggest that individuals experience a heightened positive mood compared to their own average mood, concurrently or immediately after engaging in alcohol or cannabis use. Heightened positive mood might be an anticipatory effect of drinking or cannabis use. Future research should consider a longer study period to capture multiple drinking or drug use events over a longer period and consider more environmental exposures that may influence the frequency or intensity of substance use.

  • Examining Sleep Disturbance Among Sheltered and Unsheltered Transition Age Youth Experiencing Homelessness

    by Brian Ba Redline, Sara Lcsw Semborski, Danielle R. Madden, Harmony Rhoades, Benjamin F. Henwood

    Background: The estimated 3.5-million transition age youth (TAY) who experience homelessness in the United States annually are routinely exposed to inadequate sleep environments and other psychosocial risk factors for deficient sleep. Although staying in a shelter versus being unsheltered may facilitate sleep, research suggests that perceived safety wherever one sleeps may be just as important. In this study, which is the first known study to investigate sleep disturbances among TAY experiencing homelessness, we examine associations of sleep disturbances with sheltered status and perceived safety of usual sleep environment. Methods: We surveyed TAY (aged 18–25) experiencing homelessness in Los Angeles, CA about their sleep, psychosocial health, and living situations. Participants (n=103; 60% sheltered) self-reported sleep disturbances using the Patient-Reported Outcomes Measurement Information System Sleep Disturbance short form, while individual items assessed sheltered status and perceived safety where they usually slept. Regression analyses examined associations of sheltered status and perceived sleep environment safety with sleep disturbance, adjusting for age, sex, race, self-rated health, depression symptoms, serious mental illness, high-risk drinking, and severe food insecurity. Results: Twenty-six percent of participants reported moderate-severe sleep disturbances. Sleep disturbance was not associated with sheltered status, but was positively associated with feeling unsafe in one’s sleep environment, depression symptoms, severe food insecurity, and decreased age. Conclusions: Our findings suggest that sleep disturbances among TAY experiencing homelessness are associated more closely with how safe one feels rather than one’s sheltered status. This highlights the importance of providing safe places to live for sheltered and unsheltered TAY.

    Investigating Sleep Disturbance and Its Correlates Among Formerly Homeless Adults in Permanent Supportive Housing

    by Benjamin F. PhD Henwood, Harmony Rhoades, Eldin Dzubur, Danielle R. Madden, Brian Ba Redline, Rebecca T. Brown

    Background: Adults experiencing homelessness have a high burden of sleep disturbance, which may be reduced by accessing permanent supportive housing. Objectives: To assess sleep disturbances and their correlates, including demographics, activity level, health status, age-related health issues (eg, functionality and cognitive impairment), substance use, and homelessness history in a sample of permanent supportive housing (PSH) tenants. Research Design: Cross-sectional survey design. Subjects: A total of 237 formerly homeless adults between 45 and 80 years old. Measures: The Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance short form was used to measure sleep disturbance. Results: Twenty-eight percent of our sample had PROMIS scores indicative of a moderate or severe sleep disturbance. Functional impairment, pain, and mental health comorbidities were associated with increased sleep disturbance in multivariable linear regression analyses. The number of years a person experienced homelessness was inversely associated with sleep disturbance. Conclusions: This study supports the need to screen for sleep disturbances among PSH tenants. The findings suggest that supportive services in PSH may need to include integrated physical and behavioral health care, pain management, and interventions designed to address activities of daily livings to improve tenant sleep. They also suggest that improved sleep may help reduce PSH tenant pain, impairment, and mental health symptoms among PSH tenants.


  • Practice Facilitation in Integrated Behavioral Health and Primary Care Settings: a Scoping Review

    by Elizabeth Siantz, Brian Redline, Benjamin Henwood

    Little is known about the contributions of practice facilitators in settings aiming to deliver integrated behavioral health and primary care. This scoping review identifies peer-reviewed articles that describe efforts to deliver integrated behavioral health care with the support of practice facilitators. Five databases were systematically searched to identify empirical and conceptual papers. Fourteen articles met the following inclusion criteria: (1) empirical studies evaluating the effectiveness of practice facilitation (n = 4), (2) study protocols that will test the effectiveness of practice facilitation (n = 2), (3) studies that included practice facilitators as part of a larger intervention without evaluating their effectiveness (n = 5), and (4) conceptual manuscripts endorsing practice facilitation for integrated care (n = 3). Practice facilitators can potentially support health systems in delivering integrated behavioral health care, but future research is needed to understand their necessary qualifications, the effectiveness of practice facilitation these efforts, and what study outcomes are appropriate for evaluating whether practice facilitation has been effective.

    Surveying Tenants of Permanent Supportive Housing in Skid Row about COVID-19

    by Benjamin F. Henwood, Brian Redline, Jack Lahey

    Permanent supportive housing (PSH) enrolls highly vulnerable homeless adults who experience early onset of geriatric conditions and require in-home support. Thus, there is potentially a high risk for COVID-19 within PSH, which may necessitate tenants to take protective measures. This study reports on survey results collected from 532 PSH tenants in Los Angeles, California during the 4 th week of March in 2020. Results show that nearly all tenants were aware of COVID-19, and 65% considered it to be a very serious health threat. The latter characteristic was a strong predictor of taking protective measures (i.e., handwashing and social distancing). Tenants in units with shared bathroom facilities had lower odds of social distancing than those in studio apartments. Tenants with mental health diagnoses had lower odds of consistent handwashing. Lack of access to food, hygiene items, and medication delivery were commonly reported barriers to sheltering in place.
