Enhancing detection of SARS-CoV-2 re-infections using longitudinal sero-monitoring: demonstration of a methodology in a cohort of people experiencing homelessness in Toronto, Canada.

BACKGROUND: Accurate estimation of SARS-CoV-2 re-infection is crucial to understanding the connection between infection burden and adverse outcomes. However, relying solely on PCR testing results in underreporting. We present a novel approach that includes longitudinal serologic data, and compared it against testing alone among people experiencing homelessness. METHODS: We recruited 736 individuals experiencing homelessness in Toronto, Canada, between June and September 2021. Participants completed surveys and provided saliva and blood serology samples every three months over 12 months of follow-up. Re-infections were defined as: positive PCR or rapid antigen test (RAT) results > 90 days after initial infection; new serologic evidence of infection among individuals with previous infection who sero-reverted; or increases in anti-nucleocapsid in seropositive individuals whose levels had begun to decrease. RESULTS: Among 381 participants at risk, we detected 37 re-infections through PCR/RAT and 98 re-infections through longitudinal serology. The comprehensive method identified 37.4 re-infection events per 100 person-years, more than four-fold more than the rate detected through PCR/RAT alone (9.0 events/100 person-years). Almost all test-confirmed re-infections (85%) were also detectable by longitudinal serology. CONCLUSIONS: Longitudinal serology significantly enhances the detection of SARS-CoV-2 re-infections. Our findings underscore the importance and value of combining data sources for effective research and public health surveillance.

Incidence of SARS-CoV-2 Infection Among People Experiencing Homelessness in Toronto, Canada.

Importance: People experiencing homelessness are at high risk of SARS-CoV-2 infection. Incident infection rates have yet to be established in these communities and are needed to inform infection prevention guidance and related interventions. Objective: To quantify the SARS-CoV-2 incident infection rate among people experiencing homelessness in Toronto, Canada, in 2021 and 2022 and to assess factors associated with incident infection. Design, Setting, and Participants: This prospective cohort study was conducted among individuals aged 16 years and older who were randomly selected between June and September 2021 from 61 homeless shelters, temporary distancing hotels, and encampments in Toronto, Canada. Exposures: Self-reported housing characteristics, such as number sharing living space. Main Outcomes and Measures: Prevalence of prior SARS-CoV-2 infection in summer 2021, defined as self-reported or polymerase chain reaction (PCR)- or serology-confirmed evidence of infection at or before the baseline interview, and SARS-CoV-2 incident infection, defined as self-reported or PCR- or serology-confirmed infection among participants without history of infection at baseline. Factors associated with infection were assessed using modified Poisson regression with generalized estimating equations. Results: The 736 participants (415 of whom did not have SARS-CoV-2 infection at baseline and were included in the primary analysis) had a mean (SD) age of 46.1 (14.6) years; 486 (66.0%) self-identified as male. Of these, 224 (30.4% [95% CI, 27.4%-34.0%]) had a history of SARS-CoV-2 infection by summer 2021. Of the remaining 415 participants with follow-up, 124 experienced infection within 6 months, representing an incident infection rate of 29.9% (95% CI, 25.7%-34.4%), or 5.8% (95% CI, 4.8%-6.8%) per person-month. Report after onset of the SARS-CoV-2 Omicron variant was associated with incident infection, with an adjusted rate ratio (aRR) of 6.28 (95% CI, 3.94-9.99). Other factors associated with incident infection included recent immigration to Canada (aRR, 2.74 [95% CI, 1.64-4.58]) and alcohol consumption over the past interval (aRR, 1.67 [95% CI, 1.12-2.48]). Self-reported housing characteristics were not significantly associated with incident infection. Conclusions and Relevance: In this longitudinal study of people experiencing homelessness in Toronto, SARS-CoV-2 incident infection rates were high in 2021 and 2022, particularly once the Omicron variant became dominant in the region. Increased focus on homelessness prevention is needed to more effectively and equitably protect these communities.

Navigator programme for hospitalised adults experiencing homelessness: protocol for a pragmatic randomised controlled trial.

INTRODUCTION: People experiencing homelessness suffer from poor outcomes after hospitalisation due to systemic barriers to care, suboptimal transitions of care, and intersecting health and social burdens. Case management programmes have been shown to improve housing stability, but their effects on broad posthospital outcomes in this population have not been rigorously evaluated. The Navigator Programme is a Critical Time Intervention case management programme that was developed to help homeless patients with their postdischarge needs and to link them with community-based health and social services. This randomised controlled trial examines the impact of the Navigator Programme on posthospital outcomes among adults experiencing homelessness. METHODS AND ANALYSIS: This is a pragmatic randomised controlled trial testing the effectiveness of the Navigator Programme at an urban academic teaching hospital and an urban community teaching hospital in Toronto, Canada. Six hundred and forty adults experiencing homelessness who are admitted to the hospital will be randomised to receive support from a Homeless Outreach Counsellor for 90 days after hospital discharge or to usual care. The primary outcome is follow-up with a primary care provider (physician or nurse practitioner) within 14 days of hospital discharge. Secondary outcomes include postdischarge mortality or readmission, number of days in hospital, number of emergency department visits, self-reported care transition quality, and difficulties meeting subsistence needs. Quantitative outcomes are being collected over a 180-day period through linked patient-reported and administrative health data. A parallel mixed-methods process evaluation will be conducted to explore intervention context, implementation and mechanisms of impact. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Unity Health Toronto Research Ethics Board. Participants will be required to provide written informed consent. Results of the main trial and process evaluation will be reported in peer-reviewed journals and shared with hospital leadership, community partners and policy makers. TRIAL REGISTRATION NUMBER: NCT04961762.

Family physician practice patterns during COVID-19 and future intentions: Cross-sectional survey in Ontario, Canada.

OBJECTIVE: To determine the extent to which family physicians closed their doors altogether or for in-person visits during the pandemic, their future practice intentions, and related factors. DESIGN: Cross-sectional survey. SETTING: Six geographic areas in Toronto, Ont, aligned with Ontario Health Team regions. PARTICIPANTS: Family doctors practising office-based, comprehensive family medicine. MAIN OUTCOME MEASURES: Practice operations in January 2021, use of virtual care, and future plans. RESULTS: Of the 1016 (85.7%) individuals who responded to the survey, 99.7% (1001 of 1004) indicated their practices were open in January 2021, with 94.8% (928 of 979) seeing patients in person and 30.8% (264 of 856) providing in-person care to patients reporting COVID-19 symptoms. Respondents estimated spending 58.2% of clinical care time on telephone visits, 5.8% on video appointments, and 7.5% on e-mail or secure messaging. Among respondents, 17.5% (77 of 439) were planning to close their existing practices in the next 5 years. There were higher proportions of physicians who worked alone in clinics among those who did not see patients in person (27.6% no vs 12.4% yes, P<.05), among those who did not see symptomatic patients (15.6% no vs 6.5% yes, P<.001), and among those who planned to close their practices in the next 5 years (28.9% yes vs 13.9% no, P<.01). CONCLUSION: Most family physicians in Toronto were open to in-person care in January 2021, but almost one-fifth were considering closing their practices in the next 5 years. Policy makers need to prepare for a growing family physician shortage and better understand factors that support recruitment and retention.

The acceptability of financial incentives to support service engagement of adults experiencing homelessness and mental illness: a qualitative study of key stakeholder perspectives Authorship.

PURPOSE: Evidence suggests financial incentives may effectively support service engagement among people experiencing homelessness, but literature related to their acceptability in this population is limited. This study used qualitative methods to explore stakeholder perspectives on the acceptability of using financial incentives to promote service engagement among homeless adults with mental illness. METHODS: As part of a larger mixed-methods pragmatic trial of a community-based brief case management program in Toronto, Canada, twenty-two trial participants were purposefully recruited to participate in semi-structured qualitative interviews, and five service providers and seven key informants were purposefully recruited to participate in a focus group and interviews, respectively. Topics included perspectives of acceptability and lived experiences of using financial incentives to support engagement, health and well-being. Data collection occurred between April 2019 and December 2020. Data was audio-recorded and transcribed. Coding and interpretation of data was informed by grounded theory and inductive thematic analysis. RESULTS: Stakeholders held diverse views on the acceptability of financial incentives to promote service engagement in this population. Main themes across groups included moralizing recipient motivation; tensions in how best to define and respect autonomy; and consideration of potential unintended consequences for both individuals and the service system. Significant group differences within some themes emerged. CONCLUSION: Results highlight ongoing debates over using financial incentives to facilitate service engagement among adults experiencing homelessness and mental illness. Differences in stakeholder perspectives suggest the need for person-centredness in health and research settings, and balancing theoretical risks and long-term goals with likely potential for immediate benefits.

COVID-19 Vaccine Coverage and Sociodemographic, Behavioural and Housing Factors Associated with Vaccination among People Experiencing Homelessness in Toronto, Canada: A Cross-Sectional Study.

People experiencing homelessness were prioritized for COVID-19 vaccination in Toronto, Canada, due to the high risk of infection and associated complications relative to the general population. We aimed to ascertain COVID-19 vaccine coverage in this population and explore factors associated with the receipt of at least one dose. We collected survey and blood sample data from individuals ages 16+ recruited by random selection at 62 shelters, hotels and encampment sites between 16 June 2021 and 9 September 2021. We report vaccine coverage by dose number and explored sociodemographic, behavioral, health and housing factors associated with vaccination using multivariable modified Poisson regression. In total, 80.4% (95% CI 77.3-83.1%) received at least one vaccine dose, and 63.6% (CI 60.0-67.0%) received two or more doses. Vaccination was positively associated with age (every 10 years adjusted rate ratio (aRR) 1.05 [95% CI 1.03-1.08]), and receipt of influenza vaccination (aRR 1.19 [95% CI 1.11-1.27]). Factors negatively associated with vaccination included female gender (aRR 0.92 [95% CI 0.85-1.0]), Black racial self-identification (aRR 0.89 [95% CI 0.80-0.99]) and low frequencies of masking in public places (aRR 0.83 [95% CI 0.72-0.95]). COVID-19 vaccine coverage is very high among people experiencing homelessness in Toronto, suggesting advocacy and outreach efforts may have been effective.

Exploring COVID-19 vaccine uptake, confidence and hesitancy among people experiencing homelessness in Toronto, Canada: protocol for the Ku-gaa-gii pimitizi-win qualitative study.

INTRODUCTION: People experiencing homelessness are at high risk for COVID-19 and poor outcomes if infected. Vaccination offers protection against serious illness, and people experiencing homelessness have been prioritised in the vaccine roll-out in Toronto, Canada. Yet, current COVID-19 vaccination rates among people experiencing homelessness are lower than the general population. This study aims to characterise reasons for COVID-19 vaccine uptake and hesitancy among people experiencing homelessness, to identify strategies to overcome hesitancy and provide public health decision-makers with information to improve vaccine confidence and uptake in this priority population. METHODS AND ANALYSIS: The Ku-gaa-gii pimitizi-win qualitative study (formerly the COVENANT study) will recruit up to 40 participants in Toronto who are identified as experiencing homelessness at the time of recruitment. Semistructured interviews with participants will explore general experiences during the COVID-19 pandemic (eg, loss of housing, social connectedness), perceptions of the COVID-19 vaccine, factors shaping vaccine uptake and strategies for supporting enablers, addressing challenges and building vaccine confidence. ETHICS AND DISSEMINATION: Approval for this study was granted by Unity Health Toronto Research Ethics Board. Findings will be communicated to groups organising vaccination efforts in shelters, community groups and the City of Toronto to construct more targeted interventions that address reasons for vaccine hesitancy among people experiencing homelessness. Key outputs will include a community report, academic publications, presentations at conferences and a Town Hall that will bring together people with lived expertise of homelessness, shelter staff, leading scholars, community experts and public health partners.

Using financial incentives to support service engagement of adults experiencing homelessness and mental illness: A qualitative analysis of key stakeholder perspectives.

INTRODUCTION: Homelessness and mental illness are associated with poor service engagement, health and health service use outcomes. Existing literature suggests that financial incentives may effectively support service engagement of this population, but studies investigating key stakeholder perspectives are lacking. This study aimed to elicit, using qualitative methods, nuanced service user and provider experiences by using financial incentives to support service engagement among adults experiencing homelessness and mental illness. METHODS: This qualitative study is part of a larger mixed-methods pragmatic trial of financial incentives (Coordinated Access to Care for the Homeless-Financial Incentives [CATCH-FI]) within a community-based brief case management programme (CATCH) in Toronto, Ontario. Twenty-two CATCH-FI participants were purposefully recruited to participate in in-depth, semi-structured interviews; five CATCH service providers participated in a focus group and seven key informants in individual interviews. Data collection occurred between April 2019 and December 2020. All interviews and the focus group were audio-recorded and transcribed. Topic guides prompted participant perspectives on and experiences of using financial incentives to support engagement, health and well-being. Grounded theory and inductive thematic analysis guided coding and interpretation of transcripts. Triangulation and member-checking enhanced the analytical rigour and validity of findings. RESULTS: CATCH service providers, key informants and subgroup of CATCH-FI participants perceived financial incentives to directly facilitate service engagement. The majority of CATCH-FI participants however highlighted that intrinsic motivation and service quality may be relatively more important facilitators of engagement. Most study participants across stakeholder groups perceived that financial incentives have direct positive influences on health and well-being in enabling access to basic needs and simple pleasures. CONCLUSIONS: Our data suggest that for some adults experiencing homelessness and mental illness, financial incentives can directly support service engagement. In addition, financial incentives may positively impact health and well-being by easing financial stress and enabling deeper attention to individual health needs. Further research on the effectiveness and acceptability of financial incentives is needed to improve understanding and uptake of a promising intervention to support health and health service use outcomes in an underserved population. PATIENT OR PUBLIC CONTRIBUTION: Study participants provided input into the study research questions, study design, interview guides and interpretation of findings.

Decision conflict and the decision support needs of HIV PrEP-eligible Black patients in Toronto regarding the adoption of PrEP for HIV prevention.

Objectives: This study examined factors contributing to decision conflict and the decision support needs of PrEP-eligible Black patients. Methods:The Ottawa Decision Support Framework (ODSF) was used to guide the development of a key informant guide used for qualitative data collection. Black patients assessed by healthcare providers as meeting the basic criteria for starting PrEP were recruited through the St. Michael's Hospital Academic Family Health Team and clinical and community agencies in Toronto. Participants were interviewed by trained research staff. Qualitative content analysis was guided by the ODSF, and analysis was done using the Nvivo. Results: Four women and twenty-five men (both heterosexual and men who have sex with men) were interviewed. Participants reported having difficulty in decision making regarding adoption of PrEP. The main reasons for decision-conflict regading PrEP adoption were: lack of adequate information about PrEP, concerns about the side effects of PrEP, inability to ascertain the benefits or risk of taking PrEP, provider's lack of adequate time for interaction during clinical consultation, and perceived pressure from healthcare provider. Participants identified detailed information about PrEP, and being able to clarify how their personal values align with the benefits and drawbacks of PrEP as their decision support needs. Conclusion:Many PrEP-eligible Black patients who are prescribed PrEP have decision conflict which often causes delay in decision making and sometimes rejection of PrEP. Healthcare providers should offer decision support to Black patients who are being asked to consider PrEP for HIV prevention.

Exploring different methods to evaluate the impact of basic income interventions: a systematic review.

BACKGROUND: Persistent income inequality, the increase in precarious employment, the inadequacy of many welfare systems, and economic impact of the COVID-19 pandemic have increased interest in Basic Income (BI) interventions. Ensuring that social interventions, such as BI, are evaluated appropriately is key to ensuring their overall effectiveness. This systematic review therefore aims to report on available methods and domains of assessment, which have been used to evaluate BI interventions. These findings will assist in informing future program and research development and implementation. METHODS: Studies were identified through systematic searches of the indexed and grey literature (Databases included: Scopus, Embase, Medline, CINAHL, Web of Science, ProQuest databases, EBSCOhost Research Databases, and PsycINFO), hand-searching reference lists of included studies, and recommendations from experts. Citations were independently reviewed by two study team members. We included studies that reported on methods used to evaluate the impact of BI, incorporated primary data from an observational or experimental study, or were a protocol for a future BI study. We extracted information on the BI intervention, context and evaluation method. RESULTS: 86 eligible articles reported on 10 distinct BI interventions from the last six decades. Workforce participation was the most common outcome of interest among BI evaluations in the 1960-1980 era. During the 2000s, studies of BI expanded to include outcomes related to health, educational attainment, housing and other key facets of life impacted by individuals' income. Many BI interventions were tested in randomized controlled trials with data collected through surveys at multiple time points. CONCLUSIONS: Over the last two decades, the assessment of the impact of BI interventions has evolved to include a wide array of outcomes. This shift in evaluation outcomes reflects the current hypothesis that investing in BI can result in lower spending on health and social care. Methods of evaluation ranged but emphasized the use of randomization, surveys, and existing data sources (i.e., administrative data). Our findings can inform future BI intervention studies and interventions by providing an overview of how previous BI interventions have been evaluated and commenting on the effectiveness of these methods. REGISTRATION: This systematic review was registered with PROSPERO (CRD 42016051218).

Factors Associated with Readmission Among General Internal Medicine Patients Experiencing Homelessness.

BACKGROUND: People who are homeless have a higher burden of illness and higher rates of hospital admission and readmission compared to the general population. Identifying the factors associated with hospital readmission could help healthcare providers and policymakers improve post-discharge care for homeless patients. OBJECTIVE: To identify factors associated with hospital readmission within 90 days of discharge from a general internal medicine unit among patients experiencing homelessness. DESIGN: This prospective observational study was conducted at an urban academic teaching hospital in Toronto, Canada. Interviewer-administered questionnaires and chart reviews were completed to assess medical, social, processes of care, and hospitalization data. Multivariable logistic regression with backward selection was used to identify factors associated with a subsequent readmission and estimate odds ratios and 95% confidence intervals. PARTICIPANTS: Adults (N = 129) who were admitted to the general internal medicine service between November 2017 and November 2018 and who were homeless at the time of admission. MAIN MEASURES: Unplanned all-cause readmission to the study hospital within 90 days of discharge. KEY RESULTS: Thirty-five of 129 participants (27.1%) were readmitted within 90 days of discharge. Factors associated with lower odds of readmission included having an active case manager (adjusted odds ratios [aOR]: 0.31, 95% CI, 0.13-0.76), having informal support such as friends and family (aOR: 0.25, 95% CI, 0.08-0.78), and sending a copy of the patient's discharge plan to a primary care physician who had cared for the patient within the last year (aOR: 0.44, 95% CI, 0.17-1.16). A higher number of medications prescribed at discharge was associated with higher odds of readmission (aOR: 1.12, 95% CI, 1.02-1.23). CONCLUSION: Interventions to reduce hospital readmission for people who are homeless should evaluate tailored discharge planning and dedicated resources to support implementation of these plans in the community.

A Web-Based Intervention to Reduce Decision Conflict Regarding HIV Pre-Exposure Prophylaxis: Protocol for a Clinical Trial.

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) is recommended for populations at high ongoing risk for infection. There are noted racial disparities in the incidence of HIV and other sexually transmitted infections (STIs) for African, Caribbean, and Canadian Black (ACB, black) populations in Ontario, Canada. Although blacks represent only 4.7% of the Ontario population, they account for 30% of HIV prevalence and 25% of new infections in the province. The existing clinical public health practice toolkit has not been sufficient to optimize PrEP uptake, despite the overwhelming evidence of PrEP's efficacy for reducing HIV transmission risk. Since its establishment as an effective HIV prevention tool, the major focus in behavioral research on PrEP has been on understanding and improving adherence. To date, there is no known formalized intervention in place designed to support ACB men and women at high risk of making high-quality decisions regarding the adoption of PrEP as an HIV prevention practice. OBJECTIVE: We propose 2 aims to address these gaps in HIV prevention and implementation science. First, the Ottawa Decision Support Framework (ODSF) for use in the PrEP decisional needs of black patients was adapted. Second, the decision support intervention to estimate effect size compared with control conditions in reducing decision conflict and predicting adherence over 60 days was pilot tested. METHODS: In aim 1, we propose a cross-sectional qualitative descriptive study using data collected from key informant interviews with eligible PrEP patients (n=30) and surveys with health professionals (n=20) involved in HIV PrEP management. Data obtained from aim 1 will be used to develop a decision support intervention based on the ODSF. In aim 2, the adopted decision support intervention using a block-randomized design to estimate effect size compared with control conditions in reducing decision conflict and predicting adherence over 60 days was pilot tested. Hypothesis testing will be de-emphasized in favor of generating effect size estimates. RESULTS: A research award was funded on March 25, 2017 (Multimedia Appendix 1). Ethical approval was received on March 25, 2019 (with supplemental approval received on May 10, 2019). Data collection started on April 9, 2019. As of September 30, 2019, we enrolled 29 patients and 24 health care providers for aim 1. We are currently analysing the data collected for aim 1. Aim 2 is scheduled to start in May 2020. CONCLUSIONS: This study will provide evidence-based information on the decisional needs of black patients who are at risk of HIV and have been offered PrEP. The study will also test the effect of decision support intervention in reducing decision conflict, adoption of PrEP, and adherence to PrEP.

Pathways and trajectories linking housing instability and poor health among low-income women experiencing intimate partner violence (IPV): Toward a conceptual framework.

We used grounded theory to understand pathways and trajectories to housing instability (HI) and poor health among low-income women with experiences of intimate partner violence (IPV). We conducted in-depth interviews during 2010-11 with forty-one women (ages 18-45 years) living in Ontario, Canada. All women reported depressive symptoms in combination with other health problems. In addition to the direct pathway of IPV to poor health, thematic analysis revealed an indirect multi-tiered pathway with complex trajectories among IPV, HI, and poor health. These trajectories included material HI (homelessness, high mobility, evictions, problems paying rent, hiding, and landlord discrimination), psychological HI (feeling unsafe, low self-esteem, and poor control), and social trajectories (financial problems, loss of employment, income, or social networks, and leaving school). These trajectories elevated stress and decreased self-care (unhealthy behaviors, substance abuse, and reduced medical compliance) and exacerbated poor health already compromised by IPV. Depending on her specific context, each woman experienced these pathways and trajectories differently. Moreover, the women's experiences differed across three time periods: before, immediately after, and long after leaving an abusive relationship. Finally, we found that for these women, achieving stable housing was crucial for stabilizing their health.

Shrinking the language accessibility gap: a mixed methods evaluation of telephone interpretation services in a large, diverse urban health care system.

INTRODUCTION: Language interpretation services for patients who are not proficient in a country's official language(s) are essential for improving health equity across diverse populations, and achieving clinical safety and quality for both patients and providers. Nevertheless, overall use of these services remains low, regardless of how they are delivered. In Toronto, Ontario, one of the most ethnically diverse urban centres, the regional local health integration network which oversees the highest concentration of health care organizations servicing 1.2 million residents, partnered with key stakeholders to make Over-the-Phone (OPI) interpretation services broadly and economically available in 170 different languages to its diverse network of health care organizations. This evaluation aimed to assess patients' and providers' experiences with OPI in these varied settings and the impact (if any) on alternative interpretation services and on health service delivery access and quality. METHODS: This study used a two-phased sequential exploratory mixed-methods approach to evaluate the initiative. Phase I was comprised of semi-structured interviews with representatives from the program stakeholders; these findings were applied to identify appropriate survey questions and response categories, and provided context and depth of understanding to Phase II results. Phase II included web-based and self-administered surveys for both providers and patients engaging with OPI. RESULTS: Both providers and patients identified a broad range of positive impacts OPI had on health care service delivery quality and access, and high levels of satisfaction with OPI, in a variety of health care settings. Providers also revealed a marked decrease in the use of ad-hoc, nonprofessional strategies for interpretation after the implementation of OPI, and noted it had either no impact on their workload or had decreased it overall. CONCLUSIONS: OPI is clearly not the sole answer to the complex array of health care needs and access gaps that exist for persons without proficiency in their country's official language. Nevertheless, this evaluation provides compelling evidence that OPI is a valuable component, and that it may contribute to a broader range of positive impacts, and within a broader range of health care settings, than previously explored.

Where Did She Go? The Transformation of Self-Esteem, Self-Identity, and Mental Well-Being among Women Who Have Experienced Intimate Partner Violence.

BACKGROUND: Discussions on intimate partner violence (IPV) often focus on physical abuse, ignoring psychological and sexual abuse and controlling behaviors. The damage of varied forms of IPV on mental well-being in its broader form have been far less explored, especially among low-income women. Our aim was to improve our understanding of self-perceptions of mental well-being among low-income women who have experienced IPV by considering a broader definition of mental well-being that includes self-esteem and self-identity as core components. METHODS: Using qualitative methods, we present findings from in-depth interviews with 41 low-income women currently or recently experiencing abuse and housing instability. RESULTS: Women experienced varied types of violence (physical, sexual, emotional, psychological, social isolation, and controlling behaviors). Injuries resulting from physical abuse were viewed differently from those arising from emotional and psychological control. Physical injuries healed faster, whereas damage to self-esteem and identity lingered. The journey through and out of IPV is often marked by an initial erosion of sense of self (identity deconstruction) followed by the identity reconstruction through an extended process of change aimed at rebuilding self-esteem, mental well-being, self-efficacy, and ultimately self-identity. CONCLUSIONS: IPV-related training for physicians and allied health professionals should emphasize the varied nature of IPV and its impact on identity, self-esteem, and self-efficacy. Treatment should be holistic to address comorbid needs, including physical injury, mental health, and addiction problems. Consider supportive programs that integrate those living with or leaving IPV with women with past lived experience who can help women to understand the process of change and support this change in a nurturing setting.

Home mechanical ventilation in Canada: a national survey.

BACKGROUND: No comprehensive Canadian national data describe the prevalence of and service provision for ventilator-assisted individuals living at home, data critical to health-care system planning for appropriate resourcing. Our objective was to generate national data profiling service providers, users, types of services, criteria for initiation and monitoring, ventilator servicing arrangements, education, and barriers to home transition. METHODS: Eligible providers delivering services to ventilator-assisted individuals (adult and pediatric) living at home were identified by our national provider inventory and referrals from other providers. The survey was administered via a web link from August 2012 to April 2013. RESULTS: The survey response rate was 152/171 (89%). We identified 4,334 ventilator-assisted individuals: an estimated prevalence of 12.9/100,000 population, with 73% receiving noninvasive ventilation (NIV) and 18% receiving intermittent mandatory ventilation (9% not reported). Services were delivered by 39 institutional providers and 113 community providers. We identified variation in initiation criteria for NIV, with polysomnography demonstrating nocturnal hypoventilation (57%), daytime hypercapnia (38%), and nocturnal hypercapnia (32%) as the most common criteria. Various models of ventilator servicing were reported. Most providers (64%) stated that caregiver competency was a prerequisite for home discharge; however, repeated competency assessment and retraining were offered by only 45%. Important barriers to home transition were: insufficient funding for paid caregivers, equipment, and supplies; a shortage of paid caregivers; and negotiating public funding arrangements. CONCLUSIONS: Ventilatory support in the community appears well-established, with most individuals managed with NIV. Although caregiver competency is a prerequisite to discharge, ongoing assessment and retraining were infrequent. Funding and caregiver availability were important barriers to home transition.

Prolonged mechanical ventilation in Canadian intensive care units: a national survey.

BACKGROUND: We sought to describe prevalence and care practices for patients experiencing prolonged mechanical ventilation (PMV), defined as ventilation for 21 or more consecutive days and medical stability. METHODS: We provided the survey to eligible units via secure Web link to a nominated unit champion from April to November 2012. Weekly telephone and e-mail reminders were sent for 6 weeks. RESULTS: Response rate was 215 (90%) of 238 units identifying 308 patients requiring PMV on the survey day occupying 11% of all Canadian ventilator-capable beds. Most units (81%) used individualized plans for both weaning and mobilization. Weaning and mobilization protocols were available in 48% and 38% of units, respectively. Of those units with protocols, only 25% reported weaning guidance specific to PMV, and 11% reported mobilization content for PMV. Only 30% of units used specialized mobility equipment. Most units referred to speech language pathologists (88%); use of communication technology was infrequent (11%). Only 29% routinely referred to psychiatry/psychology, and 17% had formal discharge follow-up services. CONCLUSIONS: Prolonged mechanical ventilation patients occupied 11% of Canadian acute care ventilator bed capacity. Most units preferred an individualized approach to weaning and mobilization with considerable variation in weaning methods, protocol availability, access to specialized rehabilitation equipment, communication technology, psychiatry, and discharge follow-up.

Institutional care for long-term mechanical ventilation in Canada: A national survey.

INTRODUCTION: No national Canadian data define resource requirements and care delivery for ventilator-assisted individuals (VAIs) requiring long-term institutional care. Such data will assist in planning health care services to this population. OBJECTIVE: To describe institutional and patient characteristics, prevalence, equipment used, care elements and admission barriers for VAIs requiring long-term institutional care. METHODS: Centres were identified from a national inventory and snowball referrals. The survey weblink was provided from December 2012 to April 2013. Weekly reminders were sent for six weeks. RESULTS: The response rate was 84% (54 of 64), with 44 adult and 10 pediatric centres providing data for 428 VAIs (301 invasive ventilation; 127 noninvasive ventilation [NIV]), equivalent to 1.3 VAIs per 100,000 population. An additional 106 VAIs were on wait lists in 18 centres. More VAIs with progressive neuromuscular disease received invasive ventilation than NIV (P<0.001); more VAIs with chronic obstructive pulmonary disease (P<0.001), obesity hypoventilation syndrome (P<0.001) and central hypoventilation syndrome (P=0.02) required NIV. All centres used positive pressure ventilators, 21% diaphragmatic pacing, 15% negative pressure and 13% phrenic nerve stimulation. Most centres used lung volume recruitment (55%), manually (71%) and mechanically assisted cough (55%). Lack of beds and provincial funding were common admission barriers.CONCLUSIONS: Variable models and care practices exist for institutionalized care of Canadian VAIs. Patient prevalence was 1.3 per 100,000 Canadians.

Patient transitions relevant to individuals requiring ongoing ventilatory assistance: a Delphi study.

BACKGROUND: Various terms, including 'prolonged mechanical ventilation' (PMV) and 'long-term mechanical ventilation' (LTMV), are used interchangeably to distinguish patient cohorts requiring ventilation, making comparisons and timing of clinical decision making problematic. OBJECTIVE: To develop expert, consensus-based criteria associated with care transitions to distinguish cohorts of ventilated patients. METHODS: A four-round (R), web-based Delphi study with consensus defined as >70% was performed. In R1, participants listed, using free text, criteria perceived to should and should not define seven transitions. Transitions comprised: T1 - acute ventilation to PMV; T2 - PMV to LTMV; T3 - PMV or LTMV to acute ventilation (reverse transition); T4 - institutional to community care; T5 - no ventilation to requiring LTMV; T6 - pediatric to adult LTMV; and T7 - active treatment to end-of-life care. Subsequent Rs sought consensus. RESULTS: Experts from intensive care (n=14), long-term care (n=14) and home ventilation (n=10), representing a variety of professional groups and geographical areas, completed all Rs. Consensus was reached on 14 of 20 statements defining T1 and 21 of 25 for T2. 'Physiological stability' had the highest consensus (97% and 100%, respectively). 'Duration of ventilation' did not achieve consensus. Consensus was achieved on 13 of 18 statements for T3 and 23 of 25 statements for T4. T4 statements reaching 100% consensus included: 'informed choice', 'patient stability', 'informal caregiver support', 'caregiver knowledge', 'environment modification', 'supportive network' and 'access to interprofessional care'. Consensus was achieved for 15 of 17 T5, 16 of 20 T6 and 21 of 24 T7 items. CONCLUSION: Criteria to consider during key care transitions for ventilator-assisted individuals were identified. Such information will assist in furthering the consistency of clinical care plans, research trials and health care resource allocation.

Prevalence of gambling problems among the clients of a toronto homeless shelter.

Few studies have examined the prevalence of problem and pathological gambling among clients of homeless service agencies. The objective of this study was to estimate the prevalence of problem gambling among these clients. We collected primary data on gambling using the NORC diagnostic screen for disorders. Using a modified time-location recruitment approach 264 clients of a community homeless service agency were screened for lifetime gambling problems. Descriptive statistics were produced using SPSSX. The prevalence of lifetime problem gambling was 10 % and that of pathological gambling was 25 % in this sample. The prevalence of lifetime problem and pathological gambling was alarmingly high relative to the general population lifetime prevalence. Better insight into interventions for gambling that might reduce risk of homelessness will help service agencies gauge the needs of their clients and to implement change to service delivery and screening practices.
