Effectiveness of employment-based interventions for persons experiencing homelessness: A systematic review.

Employment is frequently desired by persons who experience homelessness yet is often elusive. Little is known about the range and effectiveness of employment-based interventions evaluated in existing literature on key psychosocial outcomes including employment participation, mental well-being, housing tenure, community integration and substance use. To identify and synthesise existing studies, we conducted a systematic review of effectiveness using the methodology proposed by the Joanna Briggs Institute (JBI) following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Following the removal of duplicates, we screened 13,398 titles and abstracts, and reviewed 79 studies at the full-text review stage using two independent raters. A total of 16 studies met criteria for inclusion in a narrative synthesis and were subjected to critical appraisal. The majority of studies were conducted in the US (n = 14; 87.5%) with other studies published in Canada (n = 1; 6.3%) and Australia (n = 1; 6.3%). Interventions evaluated in existing studies included combined substance use and vocational skills interventions (n = 7; 43.8%), supported employment (n = 6; 37.5%), and integrated supports including an employment component (n = 3; 18.8%). The effectiveness of these interventions on employment, mental well-being, housing tenure, community integration, and substance use is presented. Findings suggest that research evaluating employment interventions for persons who experience homelessness is in an early stage of development. Researchers and practitioners may consider collaborating with persons with lived experiences of homelessness and practitioners in co-designing and modifying existing approaches to target key outcomes more effectively. Policymakers may consider allocating resources to such initiatives to further the development of practice and research aimed at supporting persons who experience homelessness to secure and sustain employment during and following homelessness.

A systematic review of occupational therapy interventions in the transition from homelessness.

BACKGROUND: Although systematic and scoping reviews have identified a range of interventions for persons experiencing homelessness, no known reviews have captured the range and quality of intervention studies aimed at supporting a transition from homelessness. OBJECTIVES: To capture the range and quality of occupational therapy intervention studies aimed at supporting a transition to housing following homelessness. METHOD: Using Joanna Briggs Institute (JBI) guidelines, we conducted a systematic review including a critical appraisal and narrative synthesis of experimental studies. RESULTS: Eleven studies were included. Critical appraisal scores ranged from 33.3 to 88.9 of a possible score of 100 (Mdn = 62.5; IQR = 33.4). The majority of studies evaluated interventions for the development of life skills (n = 9; 81.8%), and all were conducted in the USA. Several of the included studies were exploratory evaluation and feasibility studies, and all were quasi-experimental in design. Only three studies (27.2%) incorporated a control group. Intervention strategies included (1) integrated group and individual life skills interventions (n = 6); (2) group-based life skills interventions (n = 3); and (3) psychosocial and consultative interventions (n = 2). CONCLUSIONS: Research evaluating occupational therapy interventions aimed at supporting homeless individuals as they transition to housing is in an early stage of development. SIGNIFICANCE: Implications for research and practice are discussed.

Differential Network Testing Reveals Diverging Dynamics of Organ System Interactions for Survivors and Non-survivors in Intensive Care Medicine.

Statistical network analyses have become popular in many scientific disciplines, where an important task is to test for differences between two networks. We describe an overall framework for differential network testing procedures that vary regarding (1) the network estimation method, typically based on specific concepts of association, and (2) the network characteristic employed to measure the difference. Using permutation-based tests, our approach is general and applicable to various overall, node-specific or edge-specific network difference characteristics. The methods are implemented in our freely available R software package DNT, along with an R Shiny application. In a study in intensive care medicine, we compare networks based on parameters representing main organ systems to evaluate the prognosis of critically ill patients in the intensive care unit (ICU), using data from the surgical ICU of the University Medical Centre Mannheim, Germany. We specifically consider both cross-sectional comparisons between a non-survivor and a survivor group and longitudinal comparisons at two clinically relevant time points during the ICU stay: first, at admission, and second, at an event stage prior to death in non-survivors or a matching time point in survivors. The non-survivor and the survivor networks do not significantly differ at the admission stage. However, the organ system interactions of the survivors then stabilize at the event stage, revealing significantly more network edges, whereas those of the non-survivors do not. In particular, the liver appears to play a central role for the observed increased connectivity in the survivor network at the event stage.

Effectiveness of interventions targeting community integration among individuals with lived experiences of homelessness: A systematic review.

Community integration (CI) has been identified as a key outcome of programs designed to improve the lives of homeless and recently housed individuals (Gaetz, The State of Homelessness in Canada 2016, 2016). Although researchers have explored the extent to which Housing First (HF) impacts on social integration (Quilgars & Pleace, Soc. Incl., 4, 2016), little is known about the range and effectiveness of other interventions on CI more broadly. We conducted a systematic review of experimental studies using Joanna Briggs Institute (JBI) guidelines. Our search strategy was deployed in six databases: EMBASE, CINAHL, PsychINFO, Medline, Sociological Abstracts, and Proquest Dissertations and Theses. Our search was initiated in 2017 and updated on May 5, 2019. Using the definition of CI identified by Wong & Solomon (Ment. Health Serv. Res., 4:13-28, 2002), two independent raters screened 14,158 titles and abstracts after the removal of duplicates. A total of 157 articles were subjected to full-text review. Studies published in the English language and involving participants of any age were included. We conducted a critical appraisal of 25 studies using the JBI checklists for quasi-experimental and randomised controlled trials (Tufanaru, Joanna Briggs Institute Reviewers Manual, 2017), and subsequently excluded four studies as they did not meet a pre-established quality threshold score of 50/100. A total of 21 studies were included in a narrative synthesis. Critical appraisal scores ranged from 53.8-100 (Mdn = 69.2). Interventions evaluated in existing literature included housing and housing support interventions (n = 9), HF (n = 5), psychosocial interventions (n = 5), and employment interventions (n = 2). A meta-analysis could not be performed due to the heterogeneity of outcomes in included studies. Aspects of CI measured by researchers included social (n = 17), psychological (n = 6), and physical (n = 4) integration. Studies that evaluated HF and housing and housing support interventions demonstrated surprisingly mixed or a lack of effectiveness for promoting CI. Psychosocial interventions were the most promising, specifically those which incorporated an element of peer support. Findings of literature included in this review suggests that there is inconsistency in the extent to which existing interventions are effectively targeting CI as an outcome. Furthermore, we contend that existing systems-level interventions, including HF and permanent supportive housing alone may not be enough to promote CI among homeless and formerly homeless individuals. Future research should focus on the development and evaluation of interventions that more effectively target this critical construct.

Occupational experiences of homelessness: A systematic review and meta-aggregation.

Background: Studies exploring the occupational experiences of homeless persons have grown in the past twenty years, and there is a need to identify, evaluate, and aggregate existing studies to direct future research.Objectives: To capture the scope and quality of literature exploring the occupational experiences of homeless persons in high-income countries, and to aggregate the findings of these studies to inform future research efforts.Method: Using Joanna Briggs Institute (JBI) guidelines, we conducted a systematic review including a critical appraisal, and meta-aggregation of themes in existing qualitative literature.Results: Fifteen studies were included and were of high quality (Mdn = 8/10; IQR = 2). Meta-aggregation resulted in four themes (n = 335 participants) describing the occupational experiences of homeless persons: 1) Restrictions on time use and activity engagement; 2) Activity as a means of belonging; 3) Institutional processes as determining time use; and 4) Transcending the self through doing.Conclusions: Homeless persons in high-income countries face multiple challenges to engaging in meaningful activity, which we argue is a disabling experience. Simultaneously, homeless persons demonstrate resilience by finding ways to engage in activities of meaning, and opportunities to connect with others in the face of multiple barriers.Significance: Implications for research and practice are discussed.

Determinants of Tenancy Sustainment Following Homelessness: A Systematic Review.

BACKGROUND: Tenancy sustainment-maintenance of a tenancy to avoid a premature end of tenure-is fundamental to prevention of homelessness. Understanding what enables a successful tenancy is essential in informing interventions designed to support people in leaving homelessness. OBJECTIVES: To conduct a systematic review identifying determinants associated with tenancy sustainment following homelessness. SEARCH METHODS: A detailed search of 12 electronic databases, as well as gray literature sources, was conducted in 2015 and updated in 2016. SELECTION CRITERIA: We included all study designs with a population of homeless or formerly homeless individuals in which tenancy sustainment was the primary outcome. Two reviewers independently carried out abstract and full-text reviews. QualSyst, a validated quality appraisal tool, was used in assessing the methodological quality of articles. DATA COLLECTION AND ANALYSIS: A data extraction form was developed for the review and was completed by a pair of reviewers to ensure accuracy. The heterogeneity of the studies included indicated that a narrative overview of the results was most appropriate. MAIN RESULTS: Forty-three articles reporting 38 studies were included. Determinants were categorized at 4 levels: individual, interpersonal, community, and structural. Participation in specific programs (e.g., Housing First), receipt of social support, and older age were identified as positive determinants of tenancy sustainment. CONCLUSIONS: This systematic review is the first, to our knowledge, to focus solely on tenancy sustainment as a primary outcome. Although a range of determinants associated with tenancy sustainment were identified, it was difficult to draw strong conclusions owing to the heterogeneity of the studies. Despite being a fundamental concept in homelessness research, tenancy sustainment is poorly defined and conceptualized. A deeper understanding of tenancy sustainment will inform the development and evaluation of interventions that support people in leaving homelessness and maintaining tenancies. Public Health Implications. Housing stability is central to preventing homelessness and addressing the numerous public health concerns that can co-occur with homelessness. Our review highlights that a standardized approach to measuring housing stability and more high-quality intervention studies are essential.
