A Quantitative Retrospective Exposure Assessment for Former Chrysotile Asbestos Miners and Millers from Baie Verte, NL, Canada.

Despite numerous studies of asbestos workers in the epidemiologic literature, there are very few cohort studies of chrysotile asbestos miners/millers that include high-quality retrospective exposure assessments. As part of the creation of the Baie Verte Miners' Registry in 2008, a two-dimensional job exposure matrix (JEM) was developed for estimating asbestos exposures for former chrysotile asbestos miners/millers. Industrial hygiene data collected between 1963 and 1994 were analysed to assess validity for use in a retrospective exposure assessment and epidemiologic study. Registered former employees were divided into 52 exposure groups (EGs) based on job title and department and mean asbestos concentrations were calculated for each EG. The resulting exposure estimates were linked to individual registrants' work histories allowing for the calculation of cumulative asbestos exposure for each registrant. The distribution of exposure for most EGs (82.6%) could be described as fitting a log-normal distribution, although variability within some EGs (55%) exceeded a geometric standard deviation (GSD) of 2.5. Overall, the data used to create EGs in the development of the JEM were deemed to be of adequate quality for estimating cumulative asbestos exposures for the former employees of the Baie Verte asbestos mine/mill. The variability between workers in the same job was often high and is an important factor to be considered when using estimates of cumulative asbestos exposure to adjudicate compensation claims. The exposures experienced in this cohort were comparable to those of other chrysotile asbestos miners/millers cohorts, specifically Italian and Québec cohorts.

A scoping review to identify strategies that work to prevent four important occupational diseases.

BACKGROUND: Despite being largely preventable, many occupational diseases continue to be highly prevalent and extremely costly. Effective strategies are required to reduce their human, economic, and social impacts. METHODS: To better understand which approaches are most likely to lead to progress in preventing noise-related hearing loss, occupational contact dermatitis, occupational cancers, and occupational asthma, we undertook a scoping review and consulted with a number of key informants. RESULTS: We examined a total of 404 articles and found that various types of interventions are reported to contribute to occupational disease prevention but each has its limitations and each is often insufficient on its own. Our principal findings included: legislation and regulations can be an effective means of primary prevention, but their impact depends on both the nature of the regulations and the degree of enforcement; measures across the hierarchy of controls can reduce the risk of some of these diseases and reduce exposures; monitoring, surveillance, and screening are effective prevention tools and for evaluating the impact of legislative/policy change; the effect of education and training is context-dependent and influenced by the manner of delivery; and, multifaceted interventions are often more effective than ones consisting of a single activity. CONCLUSIONS: This scoping review identifies occupational disease prevention strategies worthy of further exploration by decisionmakers and stakeholders and of future systematic evaluation by researchers. It also identified important gaps, including a lack of studies of precarious workers and the need for more studies that rigorously evaluate the effectiveness of interventions.

Training for Impact: PhD Modernization as a Key Resource for Learning Health Systems.

The Institute of Medicine (IOM) has articulated a vision of a learning health system (LHS) as one that provides the best care at lower costs and that constantly, systematically and seamlessly improves based on data and evidence (IOM 2013). The IOM identifies the four foundational characteristics of an LHS as the real-time use of data and informatics to capture the care experience, patient-clinician partnerships, incentives aligned for value and a leadership-instilled culture of learning (IOM 2013). Although much policy research and commentary has focused on informatics and incentives, relatively less has focused on the critical question of creating a culture of learning in these systems. And although its source is debated, most management gurus agree with the adage that "culture eats strategy for breakfast" (Cave 2017), which is why a focus on the cultural dimension is critically important. Some scholars have recognized the important role of human capital - and of front-line clinicians in particular - in the LHS (Verma and Bhatia 2016). In addition to clinicians, doctorally prepared individuals, such as those with a PhD in health services and policy research (HSPR) and fields such as health economics, epidemiology and health informatics, have the potential to make significant contributions to LHSs and health system reform (Bornstein 2016; Brown and Nuti 2016; CIHR-IHSPR 2016). But having a PhD in these fields is not the same as being prepared to support progress toward an LHS. As argued in other papers, substantial change in doctoral training is needed so that graduates can contribute to their full potential and help drive real innovation within the health system (Bornstein 2016; CIHR-IHSPR 2016; Reid 2016).

Training for Health System Improvement: Emerging Lessons from Canadian and US Approaches to Embedded Fellowships.

The benefits of supporting experiential learning for improved health and societal outcomes have been recognized in many countries. A number of funding organizations have developed competitive funding opportunities to support experiential learning in health system organizations outside of the traditional university setting. AcademyHealth in the US is an early innovator that pioneered the Delivery System Science Fellowship (DSSF) and inspired Canada's creation of the Health System Impact (HSI) Fellowship program. The DSSF and HSI Fellowship have similar objectives: to improve the career readiness of doctorally prepared graduates and to build research capacity within health system organizations. However, the programs have taken different approaches to achieve these objectives and operate in different healthcare systems. This paper outlines the two models of embedded fellowships, analyzes their commonalities and differences, discusses lessons learned and suggests future directions for health services and policy research training.

Developing Competencies for Health System Impact: Early Lessons Learned from the Health System Impact Fellows.

BACKGROUND: The Health System Impact (HSI) Fellowship program provides highly qualified post-doctoral fellows studying health services and policy research (HSPR) with opportunities for experiential learning, enriched core competency development and mentorship from senior-level leaders within health system organizations. Its overall aim is to prepare post-doctoral fellows with the research and professional skills, experiences and networks to make meaningful and impactful contributions in careers in academic and applied health system settings. OBJECTIVE: This study examined whether this HSI Fellowship program has contributed to the development of enriched core competencies in HSPR. METHODS: A competency assessment tool was developed and administered to the 46 fellows and their health system and academic supervisors from the inaugural HSI Fellowship cohort. Fellows' self-assessments at baseline, three months and 12 months were analyzed, along with supervisors' assessments at three and 12 months. Descriptive analyses were used to examine competency development over time. Differences by gender and between supervisor and fellow ratings were analyzed. RESULTS: HSI fellows' self-assessments indicate that they strengthened their skills in all 10 enriched core competencies. Supervisors' assessments of the fellows' competencies also improved from baseline to 12 months. Gender differences at baseline disappeared by the 12-month assessment. CONCLUSION: The HSI Fellowship provides an opportunity to develop the full suite of enriched core competencies, particularly in competency domains that are not currently emphasized in HSPR doctoral curriculum.

Exploring Mentorship as a Strategy to Build Capacity and Optimize the Embedded Scientist Workforce.

BACKGROUND: Mentorship plays a significant role in career development in academic and applied settings, but little is documented about its role in the experiential learning of academic trainees embedded in health system organizations. The experiences of the first cohort of Canada's Health System Impact (HSI) Fellowship program can provide insights into how mentorship in this innovative type of training can work. OBJECTIVES: To understand the mentorship strategies that were used and to explore fellows' and supervisors' perspectives and experiences on the effectiveness and value of those strategies. METHODS: Data from the surveys of fellows and their supervisors and a panel rooted in the lived experience of the first HSI Fellowship cohort were used. RESULTS: Health system and academic supervisors developed a range of innovative, individualized and effective approaches for guiding their fellows, such as providing the fellow with a committee of mentors within the organization, holding regular meetings with the fellow and both the health system and the academic supervisor and leveraging their own network to expand the network and resources available to the fellow. CONCLUSION: The results suggest that engaging senior leadership in health system settings has provided positive experiences for both fellows and their mentors.

Putting research in place: an innovative approach to providing contextualized evidence synthesis for decision makers.

BACKGROUND: The Contextualized Health Research Synthesis Program (CHRSP), developed in 2007 by the Newfoundland and Labrador Centre for Applied Health Research, produces contextualized knowledge syntheses for health-system decision makers. The program provides timely, relevant, and easy-to-understand scientific evidence; optimizes evidence uptake; and, most importantly, attunes research questions and evidence to the specific context in which knowledge users must apply the findings. METHODS: As an integrated knowledge translation (KT) method, CHRSP: Involves intensive partnerships with senior healthcare decision makers who propose priority research topics and participate on research teams; Considers local context both in framing the research question and in reporting the findings; Makes economical use of resources by utilizing a limited number of staff; Uses a combination of external and local experts; and Works quickly by synthesizing high-level systematic review evidence rather than primary studies. Although it was developed in the Canadian province of Newfoundland and Labrador, the CHRSP methodology is adaptable to a variety of settings with distinctive features, such as those in rural, remote, and small-town locations. RESULTS: CHRSP has published 25 syntheses on priority topics chosen by the provincial healthcare system, including: Clinical and cost-effectiveness: telehealth, rural renal dialysis, point-of-care testing; Community-based health services: helping seniors age in place, supporting seniors with dementia, residential treatment centers for at-risk youth; Healthcare organization/service delivery: reducing acute-care length of stay, promoting flu vaccination among health workers, safe patient handling, age-friendly acute care; and Health promotion: diabetes prevention, promoting healthy dietary habits. These studies have been used by decision makers to inform local policy and practice decisions. CONCLUSIONS: By asking the health system to identify its own priorities and to participate directly in the research process, CHRSP fully integrates KT among researchers and knowledge users in healthcare in Newfoundland and Labrador. This high level of decision-maker buy-in has resulted in a corresponding level of uptake. CHRSP studies have directly informed a number of policy and practice directions, including the design of youth residential treatment centers, a provincial policy on single-use medical devices, and most recently, the opening of the province's first Acute Care for the Elderly hospital unit.

The role of proximity to death in need-based approaches to health care.

OBJECTIVES: This study examines the role of proximity to death (PTD) in need-based approaches to health care by: (1) investigating whether PTD is a statistically significant, independent predictor of health-care use; and (2) estimating PTD's marginal impact on need-based allocation of health-care resources. METHODS: The primary data source is the Canadian National Population Health Survey (NPHS), a longitudinal survey that uses vital statistics to confirm deaths of the respondents. We use two-part models separately for general practitioner, specialist, and short stay inpatient hospital services. We calculate per-capita allocation, with and without PTD, from the Canadian federal government to its ten provinces and by income groups. RESULTS: PTD is a robust and important predictor of health-care resource use for each service even after adjustment for other need and non-need factors. PTD's marginal impact on allocation is relatively small in the contexts we examined, but failure to include PTD could introduce inequity in allocation by disadvantaging populations with greater need. CONCLUSIONS: PTD is an important need indicator when modeling health-care resource requirements. It deserves greater attention in need-based approaches to health-care planning and resource allocation.
