We undertook a synthesis of existing studies to re-evaluate the evidence on program mechanisms of intimate partner violence (IPV) universal screening and disclosure within a health care context by addressing how, for whom, and in what circumstances these programs work. Our review is informed by a realist review approach, which focuses on program mechanisms. Systematic, realist reviews can help reveal why and how interventions work and can yield information to inform policies and programs. A review of the scholarly literature from January 1990 to July 2010 identified 5046 articles, 23 of which were included in our study. We identified studies on 17 programs that evaluated IPV screening. We found that programs that took a comprehensive approach (i.e., incorporated multiple program components, including institutional support) were successful in increasing IPV screening and disclosure/identification rates. Four program components appeared to increase provider self-efficacy for screening, including institutional support, effective screening protocols, thorough initial and ongoing training, and immediate access/referrals to onsite and/or offsite support services. These findings support a multi-component comprehensive IPV screening program approach that seeks to build provider self-efficacy for screening. Further implications for IPV screening intervention planning and implementation in health care settings are discussed.

This qualitative study examined how homeless individuals with mental illness experience pathways into homelessness. Study participants were enrolled in the At Home/Chez Soi project, a Pan-Canadian Randomized Controlled Trial comparing the Housing First approach with Treatment as Usual for homeless individuals. This inquiry is grounded in social ecological perspective, which considers interactions between individual and structural factors. Findings from consumer narrative interviews (n = 219) revealed that individual factors, such as substance abuse, relationship conflicts and mental health issues significantly contributed to homelessness, in addition to structural transitions from foster care and institutional settings into the community. Additional structural factors entrenched participants in unsafe communities, created obstacles to exiting homelessness and amplified individual risk factors. The study findings confirm the role of individual risk factors in pathways into homelessness, but underscore the need for policies and interventions to address structural factors that worsen individual risks and create barriers to exiting homelessness.

There is strong evidence that Housing First interventions are effective in improving housing stability and quality of life among homeless people with mental illness and addictions. However, there is very little evidence on the effectiveness of Housing First in improving substance use-related outcomes in this population. This study uses a randomized control design to examine the effects of scatter-site Housing First on substance use outcomes in a large urban centre. Substance use outcomes were compared between a Housing First intervention and treatment as usual group in a sample of 575 individuals experiencing homelessness and mental illness, with or without a co-occurring substance use problem, in the At Home/Chez Soi trial in Toronto, Canada. Generalized linear models were used to compare study arms with respect to change in substance use outcomes over time (baseline, 6, 12, 18 and 24 month). At 24 months, participants in the Housing First intervention had significantly greater reductions in number of days experiencing alcohol problems and amount of money spent on alcohol than participants in the Treatment as Usual group. No differences between the study arms in illicit drug outcomes were found at 24 months. These findings show that a Housing First intervention can contribute to reductions in alcohol problems over time. However, the lack of effect of the intervention on illicit drug problems suggests that individuals experiencing homelessness, mental illness and drug problems may need additional supports to reduce use.

A realist review of the evaluative evidence was conducted on integrated care (IC) programs for older adults to identify key processes that lead to the success or failure of these programs in achieving outcomes such as reduced healthcare utilization, improved patient health, and improved patient and caregiver experience. International academic literature was searched in 12 indexed, electronic databases and gray literature through internet searches, to identify evaluative studies. Inclusion criteria included evaluative literature on integrated, long-stay health and social care programs, published between January 1980 and July 2015, in English. Data were extracted on the study purpose, period, setting, design, population, sample size, outcomes, and study results, as well as explanations of mechanisms and contextual factors influencing outcomes. A total of 65 articles, representing 28 IC programs, were included in the review. Two context-mechanism-outcome configurations (CMOcs) were identified: (i) trusting multidisciplinary team relationships and (ii) provider commitment to and understanding of the model. Contextual factors such as strong leadership that sets clear goals and establishes an organizational culture in support of the program, along with joint governance structures, supported team collaboration and subsequent successful implementation. Furthermore, time to build an infrastructure to implement and flexibility in implementation, emerged as key processes instrumental to success of these programs. This review included a wide range of international evidence, and identified key processes for successful implementation of IC programs that should be considered by program planners, leaders and evaluators.
