Contending With Precarity: Health and Multi-Sectoral Supports for Migrant Agricultural Workers in Southern Ontario.

Research has long-documented how Canada's temporary foreign worker programs (TFWP) foster workers' precarity through their status as non-citizens and living and working conditions, ultimately, impacting their health. While studies point to limited supports and services for workers, their role in reinforcing or alleviating the precarious conditions that migrant agricultural workers experience remains largely unexplored. This paper draws on interviews with 35 service providers in three migrant-intensive regions in southwestern Ontario, to explore how service providers describe and construct support. We explore the barriers workers face in accessing services, challenges providers experience in supporting workers, and strategies employed to surmount these barriers. We argue that this multiregional analysis is important to illuminate how support shapes and is shaped by the larger structural context, namely common features of Canada's TFWP. A more comprehensive understanding of support moreover, provides direction for sustainable interventions that can promote the health and wellbeing of this population.

A Multiphase Mixed Methods Study on the Integration of a Population Health Approach in Sexual Health Programs and Services in Ontario Public Health Units.

PURPOSE: This study investigated the extent of and factors influencing implementation of a population health approach within sexual health programming in public health. METHOD: This sequential multi-phase mixed methods study combined findings from a quantitative survey assessing the extent that a population health approach was implemented in sexual health programs in Ontario public health units and qualitative interviews with sexual health managers and/or supervisors. Interviews explored factors influencing implementation and were analyzed using directed content analysis. RESULTS: Staff from fifteen of 34 public health units completed surveys and ten interviews were completed with sexual health managers/supervisors. From the 8 Population Health Key Elements Template, 6 elements were moderately implemented and 2 had low implementation. Qualitative findings focused on enablers and barriers to implementing a population health approach in sexual health programs and services and explained most of the quantitative results. However, some of the quantitative findings were not explained by qualitative data (e.g., low implementation of using the principles of social justice). CONCLUSION: Qualitative findings revealed factors influencing the implementation of a population health approach. A lack of resources available to health units, differing priorities between health units and community stakeholders, and access to evidence around population-level interventions influenced implementation.

Preliminary instrument development to measure implementing a population health approach in sexual health.

OBJECTIVES: This study aims to describe the preliminary development and validation of an instrument to measure the extent that a population health approach was applied in sexual health by public health units in Ontario, Canada. DESIGN: Preliminary scale development and administration occurred in two phases that included item development and validity testing. MEASUREMENT AND SAMPLE: Two phases of development included: (1) using literature and expert input (n = 6) to develop items; and (2) validation of items by content experts (n = 5) and pre-testing (n = 3). RESULTS: The validated scale consisted of 69 items across the eight key elements of a population health approach. 15 out of 35 health units completed the survey, representing 43% of health units. Instrument administration revealed that Focus on the Health of Populations and Address the Determinants of Health and their Interactions were implemented more frequently compared to Collaborate Across Sectors and Levels and Employ Mechanisms for Public Involvement, which were infrequently implemented. CONCLUSION: This preliminary scale is a way for sexual health programs to measure the extent that a population health approach is implemented by their organization. Further testing with a broader sample is needed to strengthen generalizability and address reliability.

Influences on the uptake of a population health approach to sexual health programs in Ontario public health units: a qualitative descriptive study.

Aim: Population-level prevention initiatives are the cornerstone of public health practice. However, despite this normative practice, sexual health programming within public health has not utilized this approach to the same extent as other public health programs. Understanding requirements to put a population-level approach into practice is needed. The objective of this study was to explore the barriers and facilitators experienced by sexual health programs and services within public health when implementing a population health approach. Subject design and methods: The principles of qualitative description guided all sampling, data collection and analysis decisions. Data collection involved in-depth semi-structured interviews with 12 sexual health managers and/or supervisors from ten Ontario public health units. Directed content analysis was used to code and synthesize the data. Data collection and analysis was guided using constructs from the Consolidated Framework for Implementation Research. Results: Factors that served as either barriers and facilitators to implementing a population health approach, were mainly in the inner and outer setting domains of the Consolidated Framework for Implementation Research. Participants identified the presence of community partnerships, adequate staff training on population health, and access to data on population health served as facilitators. In comparison, barriers to implementation included a lack of resources (human, financial) and clinicians' value of and preferences for delivering services at the individual clinic level. Conclusion: Some clear barriers and facilitators influenced if staff in sexual health programs and services could implement a population health approach. Results indicate where public health resources need to be enhanced to move toward a population health approach and provide insight into what worked and should be considered by public health organizations.

Parents' and Staff Perceptions of Parental Needs During a Child's Hospital Admission: An Australian Study.

PURPOSE: This study aimed to identify parents' and staff perceptions of parents' needs during a hospital admission and relationships between needs, socio-demographic and clinical variables. DESIGN AND METHODS: A cross-sectional descriptive design. Forty-six parents whose child received care and 17 staff who worked within a paediatric ward at a secondary hospital in Western Australia completed the Needs of Parents' Questionnaire in 2016. RESULTS: Parent and staff perceptions of the importance of needs were congruent but differences arose between parents and staff on whether these needs were met and needed. Parents were more likely to rate needs as less important, more met and more needed than staff members. Demographic characteristics significantly influenced parents' and staff perceptions of parents' needs in hospital. CONCLUSIONS: Staff need to acknowledge that the parent and child's hospital trajectory and demographical characteristics can influence the parent and child's needs in hospital. For family centred healthcare delivery to be effective, care delivery needs to be aligned to what parents and children state their needs are at that time. PRACTICE IMPLICATIONS: This study has highlighted that future international collaborative research networks are needed to critique the concepts and clinical implications of FCC from a broader lens and recipients, deliverers and providers of healthcare need to be cognisance of contemporary FCC literature.

Predicting success in medical school: a longitudinal study of common Australian student selection tools.

BACKGROUND: Medical student selection and assessment share an underlying high stakes context with the need for valid and reliable tools. This study examined the predictive validity of three tools commonly used in Australia: previous academic performance (Grade Point Average (GPA)), cognitive aptitude (a national admissions test), and non-academic qualities of prospective medical students (interview). METHODS: A four year retrospective cohort study was conducted at Flinders University Australia involving 382 graduate entry medical students first enrolled between 2006 and 2009. The main outcomes were academic and clinical performance measures and an indicator of unimpeded progress across the four years of the course. RESULTS: A combination of the selection criteria explained between 7.1 and 29.1 % of variance in performance depending on the outcome measure. Weighted GPA consistently predicted performance across all years of the course. The national admissions test was associated with performance in Years 1 and 2 (pre-clinical) and the interview with performance in Years 3 and 4 (clinical). Those students with higher GPAs were more likely to have unimpeded progress across the entire course (OR = 2.29, 95 % CI 1.57, 3.33). CONCLUSIONS: The continued use of multiple selection criteria to graduate entry medical courses is supported, with GPA remaining the single most consistent predictor of performance across all years of the course. The national admissions test is more valuable in the pre-clinical years, and the interview in the clinical years. Future selections research should develop the fledgling research base regarding the predictive validity of the Graduate Australian Medical School Admissions Test (GAMSAT), the algorithms for how individual tools are combined in selection, and further explore the usefulness of the unimpeded progress index.

Nurse perceptions of family home-visiting programmes in Australia and England.

AIMS: Nurse home-visiting programmes are employed to enhance the functioning of disadvantaged mothers and young children. Despite the key role played by nurses, there is little empirical evidence describing the views and experiences of nurses who deliver home-visiting programmes. This study compared the views and experiences of nurses delivering home-visiting programmes in England and South Australia. METHODS: Participants were 108 nurses delivering the South Australian Family Home Visiting programme (2008-2011), and 44 nurses delivering the Family Nurse Partnership programme in England (2007-2009). Data were collected using a standard questionnaire that was completed by nurses in each country. The questionnaire asked nurses about their level of influence on programme outcomes, approaches they used to retain maternal engagement with the home-visiting programmes, barriers to effective programme delivery and the effectiveness of supervision. RESULTS: Both groups of nurses considered that their greatest influence was improving mothers' confidence with parenting skills and increasing mothers' knowledge about children's development. Each group identified quality of nurse-mother relationships as the factor most relevant to retaining maternal engagement. Other influential factors were flexibility of timing for visits and the capacity of the programmes to meet specific needs of mothers. CONCLUSION: There was consistency in the nurses' views about the home-visiting programmes delivered in England and Australia. Future studies should utilise prospective designs to identify the mechanisms by which factors influence the quality of nurse-mother relationships, approaches used by nurses to solve family problems and elements of mother-nurse relationships that have the strongest influence on programme outcomes.

Effectiveness of nurse home-visiting for disadvantaged families: results of a natural experiment.

OBJECTIVE: To evaluate the effects of a postnatal home-visiting programme delivered by community health nurses to socially disadvantaged mothers in South Australia. DESIGN: The intervention group of 428 mothers lived in metropolitan Adelaide and the comparison group of 239 mothers lived in regional towns where the programme was not yet available. All participating mothers met health service eligibility criteria for enrolment in the home-visiting programme. Participants in both groups were assessed at baseline (mean child age=14.4 weeks SD=2.3), prior to programme enrolment, and again when the children were aged 9, 18 and 24 months. SETTING: State-wide community child health service. PARTICIPANTS: 667 socially disadvantaged mothers enrolled consecutively. 487 mothers (73%) completed the 24-month assessment. INTERVENTION: Two-year postnatal home-visiting programme based on the Family Partnership Model. PRIMARY OUTCOME MEASURES: Parent Stress Index (PSI), Kessler Psychological Distress Scale and the Ages and Stages Questionnaire. RESULTS: Mixed models adjusting for baseline differences were used to compare outcomes in the two groups. The mothers in the home-visiting group reported greater improvement on the PSI subscales assessing a mother's perceptions on the quality of their relationship with their child (1.10, 95% CI 0.06 to 2.14) and satisfaction with their role as parents (0.46, 95% CI -0.15 to 1.07) than mothers in the comparison group. With the exception of childhood sleeping problems, there were no other significant differences in the outcomes across the two groups. CONCLUSIONS: The findings suggest that home-visiting programmes delivered by community health nurses as part of routine clinical practice have the potential to improve maternal-child relationships and help mothers adjust to their role as parents.

Legacy Mentors: translating the wisdom of our senior nurses.

'Legacy Mentors' are nurses aged 55 or older with a wealth of knowledge and passion to share with other nurses. Finding ways to capture their wisdom, disseminate their expertise, and potentially retain them longer is critical. As part of an innovative Educator Pathway project in two health authorities in British Columbia, Canada, nurses with up to 40 years of experience proposed to share their wisdom and translate their expertise for the next generation of nurses. The Legacy Mentor Project involved 29 nurses who developed projects to share knowledge with students, novice and experienced nurses in their work settings. The project included an orientation workshop to facilitate project start-up, a mid-way workshop for sharing progress, and a celebration event in September 2009 which highlighted their learning and final outcomes in. Project evaluation through surveys, focus groups and interviews revealed that the nurses' expertise was validated, suggesting that the translation of expertise by re-energized nurses is a strategy with potential to enhance retention of our most experienced nurses while also enhancing practice learning environments. Unexpected outcomes were reciprocal learning and changing practice of nursing peers through modelling and discussion. This paper will describe the process and outcomes of this pilot project, including description of the projects completed by the Legacy Mentors.

Nurse Educator Pathway Project: a competency-based intersectoral curriculum.

In this paper, we begin by providing an overview of the Educator Pathway Project (EPP), an education infrastructure that was developed in response to emerging critical nursing workplace issues, and the related demand for enhanced workplace education. We then describe the EPP competency-based curriculum designed to prepare nurses as preceptors, mentors, and educators to lead learning with diverse learner groups. This competency-based curriculum was developed through a collaboration of nurse leaders across practice, academic, and union sectors and drew from a widely embraced curriculum development model (Iwasiw, Goldenberg, & Andrusyzyn, 2005). The goal of the curriculum was to prepare nurses through a four-level career pathway model that contextualized practice and education theory to various education-related roles and levels of experience within the practice setting. Over 1,100 nurses participated in this innovative intersectoral nursing initiative.

Dofetilide is safe and effective in preventing atrial fibrillation recurrences in patients accepted for catheter ablation.

AIMS: The aim of this study was to assess the safety and efficacy of dofetilide among patients refractory to other anti-arrhythmic drugs (AADs) and accepted for atrial fibrillation (AF) ablation. METHODS AND RESULTS: One hundred and twenty-seven of 454 patients (69% male, 58% paroxysmal, age 60 +/- 10 years, AF duration 8 +/- 7 years) scheduled for AF ablation between February 2004 and May 2008 were treated with dofetilide. Patients had failed 1.9 +/- 1.1 AADs. Anti-arrhythmic drugs were stopped five half-lives before ablation and 3 months for amiodarone. Patients were followed for 15 +/- 7 months with routine and symptom-driven monitoring. Success was defined as no further AF and partial success as a 50% reduction in frequency/duration of AF episodes. Thirty-six patients started dofetilide 158 +/- 167 days before ablation: 9 had no improvement, 16 experienced partial success, 8 had no further AF, and 2 improved enough to forgo ablation. Seventy-one patients started dofetilide immediately following ablation, of which 14 had no improvement, 22 experienced partial success, and 32 had no further AF. Twenty patients started dofetilide 119 +/- 153 days post-ablation, of which four had no improvement, seven experienced partial success, and nine had no further AF. Six patients discontinued dofetilide during initiation for QT prolongation. CONCLUSION: Dofetilide appears safe and effective in preventing AF in patients refractory to other AADs undergoing catheter ablation.

Serum leptin in NASH correlates with hepatic steatosis but not fibrosis: a manifestation of lipotoxicity?

Nonalcoholic steatohepatitis (NASH) is a disorder characterized by hepatic steatosis, inflammation, and fibrosis. Leptin is an adipocyte-derived antiobesity hormone that in rodents prevents "lipotoxicity" by limiting triglyceride accumulation and also regulates matrix deposition (fibrosis) during wound healing. We therefore determined serum leptin levels in patients with NASH to determine whether relationships existed between leptin levels and severity of hepatic steatosis or fibrosis. We used a radioimmunoassay to determine serum [total] leptin concentrations in 27 men and 20 women with NASH and 47 controls matched for gender and body mass index (BMI; and partly for age). Serum leptin values were correlated with hepatic steatosis, fibrosis, and inflammation (each categorized semiquantitatively on liver histology), and with anthropometric indices, serum lipids, glucose, insulin, c-peptide, and alanine aminotransferase (ALT) levels. Compared with the controls, mean serum leptin levels were raised in both men and women with NASH (men 14 +/- 11 ng/mL vs. 7.2 +/- 4.1 ng/mL, P =.003; women 35 +/- 16 ng/mL vs. 15 +/- 8.2 ng/mL, P <.001). Leptin values correlated with serum c-peptide levels but not with BMI. In a multivariate analysis, serum leptin (P =.027), serum c-peptide (P =.001), and age (P =.027) were selected as independent predictors of the severity of hepatic steatosis. However, serum leptin was not an independent predictor of hepatic inflammation or fibrotic severity. In conclusion, hyperleptinemia occurs in NASH and is not explained simply by gender, obesity, or the presence of type 2 diabetes. Furthermore, leptin levels correlate directly with the severity of hepatic steatosis but not with inflammation or fibrosis. We propose that the relationship between leptin and steatosis reflects a pathogenic role of leptin in hepatic insulin resistance and/or a failure of the antisteatotic actions of leptin ("peripheral leptin resistance").
