A structured approach to modifying an implementation package while scaling up a complex evidence-based practice.

OBJECTIVE: To describe a structured, iterative, data-driven approach for modifying implementation strategies for a complex evidence-based practice during a nationwide scale-up initiative. DATA SOURCES AND STUDY SETTING: We scaled-up implementation of Critical Time Intervention (CTI)-an evidence-based case management model-across 32 diverse community-based Veterans Affairs (VA) "Grant and Per Diem" case management (GPD-CM) agencies that serve homeless-experienced Veterans transitioning to independent living. Primary data were collected using qualitative methods. STUDY DESIGN: We embarked on a scale-up initiative while conducting a pragmatic randomized evaluation using a roll-out design, comparing two versions of a CTI implementation package tailored to VA's GPD-CM program. We iteratively assessed contextual factors and implementation outcomes (e.g., acceptability); findings informed package modifications that were characterized using the Framework for Reporting Adaptations and Modifications to Evidence-based Implementation Strategies. DATA COLLECTION METHODS: We conducted semi-structured interviews with Veterans, GPD-CM staff, and liaising VA clinicians; periodic reflections with liaising VA clinicians and implementation team members; and drew upon detailed meeting notes. We used rapid qualitative methods and content analysis to integrate data and characterize modifications. PRINCIPAL FINDINGS: After each scale-up wave-in response to variations in agency-level characteristics- we made iterative modifications to the implementation package to increase CTI adoption and fidelity across the diverse contexts of our scale-up sites. Modifications included adding, deleting, integrating, and altering the package; core package components were preserved. CONCLUSIONS: Implementation packages for complex evidence-based practices undergoing scale-up in diverse contexts may benefit from iterative modifications to optimize practice adoption with fidelity. We offer a structured, pragmatic approach for iteratively identifying data-driven, midstream implementation package adjustments, for use in both VA and non-VA scale-up initiatives. Our project demonstrates the importance of assessing for and making modifications in a scale-up initiative, as well as the trade-offs of projects having simultaneous formative and summative evaluation aims.

Informing implementation and dissemination of a specialized primary care medical home for patients with serious mental illness: Clinician and administrator perspectives.

People with serious mental illness (SMI) have lower rates of use of preventative medical services and higher rates of mortality compared to the general population. Research shows that specialized primary care medical homes improve the health care of patients with SMI and are feasible to implement, safe, and more effective than usual care. However, specialized medical homes remain uncommon and model dissemination limited. As part of a controlled trial assessing an SMI-specialized medical home, we examined clinician and administrator perspectives regarding specialized versus mainstream primary care and identified ways to enhance the scale-up of a specialized primary care model for future dissemination. We conducted semistructured interviews with clinicians and administrators at three sites prior to the implementation of an SMI-specialized primary care medical home (n = 26) and at 1-year follow-up (n = 24); one site implemented the intervention, and two sites served as controls. Interviews captured service design features that affected the quality of care provided; contextual factors that supported or impeded medical home implementation; and knowledge, attitudes, and behaviors regarding the care of patients with SMI. Interviews were transcribed and coded. Clinicians and administrators described SMI-specialized primary care medical homes as advancing care coordination and outcomes for patients with SMI. Stakeholders identified elements of a specialized medical home that they viewed as superior to usual care, including having a holistic picture of patients' needs and greater care coordination. However, to enable scale-up, efforts are needed to increase staffing on care teams, develop robust clinician onboarding or training, and ensure close coordination with mental health care providers.

Insights for Conducting Large-Scale Surveys with Veterans Who Have Experienced Homelessness.

Surveys of underserved patient populations are needed to guide quality improvement efforts but are challenging to implement. The goal of this study was to describe recruitment and response to a national survey of Veterans with homeless experience (VHE). We randomly selected 14,340 potential participants from 26 U.S. Department of Veterans Affairs (VA) facilities. A survey contract organization verified/updated addresses from VA administrative data with a commercial address database, then attempted to recruit VHE through 4 mailings, telephone follow-up, and a $10 incentive. We used mixed-effects logistic regressions to test for differences in survey response by patient characteristics. The response rate was 40.2% (n=5,766). Addresses from VA data elicited a higher response rate than addresses from commercial sources (46.9% vs 31.2%, p<.001). Residential addresses elicited a higher response rate than business addresses (43.8% vs 26.2%, p<.001). Compared to non-respondents, respondents were older, less likely to have mental health, drug, or alcohol conditions, and had fewer VA housing and emergency service visits. Collectively, our results indicated a national mailed survey approach is feasible and successful for reaching VA patients who have recently experienced homelessness. These findings offer insight into how health systems can obtain perspectives of socially disadvantaged groups.

Risk and Resilience Factors for Youth Homelessness in Western Countries: A Systematic Review.

OBJECTIVES: The experience of homelessness for young people can affect social, emotional, and physical development, resulting in poorer physical and mental health outcomes. To reduce rates of youth homelessness, a better understanding of both risk and resilience is needed to inform future intervention development. This article presents a systematic review of published research reporting risk or resilience factors related to homelessness among young people in Western countries. METHODS: After thorough examination for inclusion criteria, 665 abstracts of peer-reviewed quantitative studies of risk or resilience factors for homelessness among young people (ages 0-25) that included an adequate comparison group (e.g., not homeless) were selected. After abstract and full-text screening, 16 articles were reviewed. A primary prevention framework was used to create an explanatory model for the onset of homelessness using risk and resilience factors. RESULTS: Common risk factors for youth homelessness included difficulties with family, mental health or substance use problems, a history of problem behaviors, a history of foster care, homelessness as a child, and running away. Common protective factors included a supportive family, a college education, and high socioeconomic status. Findings were integrated into a provisional developmental model of youth homelessness risk. Clinical implications of the model for service development are discussed, and a model for monitoring homelessness risk and resilience factors is proposed. CONCLUSIONS: Factors affecting homelessness risk among youths and adults differ, with family, foster care, and schooling playing a much more important role among youths. Findings highlight opportunities for youth homelessness prevention strategies and monitoring.

Characteristics Associated With Unsheltered Status Among Veterans.

INTRODUCTION: Unsheltered homelessness is a strongly debated public issue. The study objective is to identify personal and community characteristics associated with unsheltered homelessness in veterans and to test for interactions between these characteristics. METHODS: In a 2018 national survey of U.S. veterans with homeless experiences; investigators assessed unsheltered time; psychosocial characteristics; and community measures of shelter access, weather, and rental affordability. Associations between these characteristics and unsheltered status were tested in July-August 2020. This study also tested whether the count of personal risk factors interacted with community characteristics in predicting unsheltered status. RESULTS: Among 5,406 veterans, 481 (8.9%) reported ≥7 nights unsheltered over 6 months. This group was more likely to report criminal justice history, poor social support, medical and drug problems, financial hardship, and being unmarried. Their communities had poorer shelter access and warmer temperatures. The likelihood of unsheltered experience rose with risk factor count from 2.0% (0-1) to 8.4% (2-3) and to 24.2% (4-11). Interaction tests showed that the increase was greater for communities with warmer weather and higher rents (p<0.05). CONCLUSIONS: Among veterans experiencing homelessness, unsheltered experiences correlate with individual and community risk factors. Communities wishing to address unsheltered homelessness will need to consider action at both levels.

Comparison of Patient Experience Between Primary Care Settings Tailored for Homeless Clientele and Mainstream Care Settings.

BACKGROUND: More than 1 million Americans receive primary care from federal homeless health care programs yearly. Vulnerabilities that can make care challenging include pain, addiction, psychological distress, and a lack of shelter. Research on the effectiveness of tailoring services for this population is limited. OBJECTIVE: The aim was to examine whether homeless-tailored primary care programs offer a superior patient experience compared with nontailored ("mainstream") programs overall, and for highly vulnerable patients. RESEARCH DESIGN: National patient survey comparing 26 US Department of Veterans Affairs (VA) Medical Centers' homeless-tailored primary care ("H-PACT"s) to mainstream primary care ("mainstream PACT"s) at the same locations. PARTICIPANTS: A total of 5766 homeless-experienced veterans. MEASURES: Primary care experience on 4 scales: Patient-Clinician Relationship, Cooperation, Accessibility/Coordination, and Homeless-Specific Needs. Mean scores (range: 1-4) were calculated and dichotomized as unfavorable versus not. We counted key vulnerabilities (chronic pain, unsheltered homelessness, severe psychological distress, and history of overdose, 0-4), and categorized homeless-experienced veterans as having fewer (≤1) and more (≥2) vulnerabilities. RESULTS: H-PACTs outscored mainstream PACTs on all scales (all P<0.001). Unfavorable care experiences were more common in mainstream PACTs compared with H-PACTs, with adjusted risk differences of 11.9% (95% CI=6.3-17.4), 12.6% (6.2-19.1), 11.7% (6.0-17.3), and 12.6% (6.2-19.1) for Relationship, Cooperation, Access/Coordination, and Homeless-Specific Needs, respectively. For the Relationship and Cooperation scales, H-PACTs were associated with a greater reduction in unfavorable experience for patients with ≥2 vulnerabilities versus ≤1 (interaction P<0.0001). CONCLUSIONS: Organizations that offer primary care for persons experiencing homelessness can improve the primary care experience by tailoring the design and delivery of services.

Perceptions of Care Coordination Among Homeless Veterans Receiving Medical Care in the Veterans Health Administration and Community Care Settings: Results From a National Survey.

BACKGROUND: Initiatives to expand Veterans' access to purchased health care outside Veterans Health Administration (VHA) facilities ("community care") present care coordination challenges for Veterans experiencing homelessness. OBJECTIVE: Among Veterans with homeless experiences, to evaluate community care use and satisfaction, and compare perceptions of care coordination among Veterans using VHA services and community care to those using VHA services without community care. RESEARCH DESIGN: Cross-sectional analysis of responses to a 2018 mailed survey. SUBJECTS: VHA outpatients with homeless experiences. MEASURES: Self-reported use of community care, Likert-style ratings of satisfaction with that care, and Access/Coordination experiences from the Primary Care Quality-Homeless (PCQ-H) survey. RESULTS: Of 4777 respondents, 1325 (26.7%) reported using community care; most of this subsample affirmed satisfaction with the community care they received (83%) and its timeliness (75%). After covariate adjustment, Veteran characteristics associated with greater community care use included female sex, being of retirement age and nonmarried, and having higher education, more financial hardship, ≥3 chronic conditions, psychological distress, depression, and posttraumatic stress disorder. Satisfaction with community care was lower among patients with travel barriers, psychological distress, and less social support. Compared with those using the VHA without community care, Veterans using VHA services and community care were more likely to report unfavorable access/coordination experiences [odds ratio (OR)=1.34, confidence interval (CI)=1.15-1.57]. This included hassles following referral (OR=1.37, CI=1.14-1.65) and perceived delays in receiving health care (OR=1.38, CI=1.19-1.61). CONCLUSIONS: Veterans with homeless experiences value community care options. Potential access benefits are balanced with risks of unfavorable coordination experiences for vulnerable Veterans with limited resources.

Prevalence of and Risk Factors Associated With Nonfatal Overdose Among Veterans Who Have Experienced Homelessness.

Importance: Individuals with a history of homelessness are at increased risk for drug or alcohol overdose, although the proportion who have had recent nonfatal overdose is unknown. Understanding risk factors associated with nonfatal overdose could guide efforts to prevent fatal overdose. Objectives: To determine the prevalence of recent overdose and the individual contributions of drugs and alcohol to overdose and to identify characteristics associated with overdose among veterans who have experienced homelessness. Design, Setting, and Participants: This survey study was conducted from November 15, 2017, to October 1, 2018, via mailed surveys with telephone follow-up for nonrespondents. Eligible participants were selected from the records of 26 US Department of Veterans Affairs medical centers and included veterans who had received primary care at 1 of these Veterans Affairs medical centers and had a history of experiencing homelessness according to administrative data. Preliminary analyses were conducted in October 2018, and final analyses were conducted in January 2020. Main Outcomes and Measures: Self-report of overdose (such that emergent medical care was obtained) in the previous 3 years and substances used during the most recent overdose. All percentages are weighted according to propensity to respond to the survey, modeled from clinical characteristics obtained in electronic health records. Results: A total of 5766 veterans completed the survey (completion rate, 40.2%), and data on overdose were available for 5694 veterans. After adjusting for the propensity to respond to the survey, the mean (SD) age was 56.4 (18.3) years; 5100 veterans (91.6%) were men, 2225 veterans (38.1%) were black, and 2345 veterans (40.7%) were white. A total of 379 veterans (7.4%) reported any overdose during the past 3 years; 228 veterans (4.6%) reported overdose involving drugs, including 83 veterans (1.7%) who reported overdose involving opioids. Overdose involving alcohol was reported by 192 veterans (3.7%). In multivariable analyses, white race (odds ratio, 2.44 [95% CI, 2.00-2.98]), self-reporting a drug problem (odds ratio, 1.66 [95% CI, 1.39-1.98]) or alcohol problem (odds ratio, 2.54 [95% CI, 2.16-2.99]), and having witnessed someone else overdose (odds ratio, 2.34 [95% CI, 1.98-2.76]) were associated with increased risk of overdose. Conclusions and Relevance: These findings suggest that nonfatal overdose is relatively common among veterans who have experienced homelessness. While overdose involving alcohol was more common than any specific drug, 1.7% of veterans reported overdose involving opioids. Improving access to addiction treatment for veterans who are experiencing homelessness or who are recently housed, especially for those who have experienced or witnessed overdose, could help to protect this population.
