The use of evidence to guide decision-making during the COVID-19 pandemic: divergent perspectives from a qualitative case study in British Columbia, Canada.

BACKGROUND: The challenges of evidence-informed decision-making in a public health emergency have never been so notable as during the COVID-19 pandemic. Questions about the decision-making process, including what forms of evidence were used, and how evidence informed-or did not inform-policy have been debated. METHODS: We examined decision-makers' observations on evidence-use in early COVID-19 policy-making in British Columbia (BC), Canada through a qualitative case study. From July 2021- January 2022, we conducted 18 semi-structured key informant interviews with BC elected officials, provincial and regional-level health officials, and civil society actors involved in the public health response. The questions focused on: (1) the use of evidence in policy-making; (2) the interface between researchers and policy-makers; and (3) key challenges perceived by respondents as barriers to applying evidence to COVID-19 policy decisions. Data were analyzed thematically, using a constant comparative method. Framework analysis was also employed to generate analytic insights across stakeholder perspectives. RESULTS: Overall, while many actors' impressions were that BC's early COVID-19 policy response was evidence-informed, an overarching theme was a lack of clarity and uncertainty as to what evidence was used and how it flowed into decision-making processes. Perspectives diverged on the relationship between 'government' and public health expertise, and whether or not public health actors had an independent voice in articulating evidence to inform pandemic governance. Respondents perceived a lack of coordination and continuity across data sources, and a lack of explicit guidelines on evidence-use in the decision-making process, which resulted in a sense of fragmentation. The tension between the processes involved in research and the need for rapid decision-making was perceived as a barrier to using evidence to inform policy. CONCLUSIONS: Areas to be considered in planning for future emergencies include: information flow between policy-makers and researchers, coordination of data collection and use, and transparency as to how decisions are made-all of which reflect a need to improve communication. Based on our findings, clear mechanisms and processes for channeling varied forms of evidence into decision-making need to be identified, and doing so will strengthen preparedness for future public health crises.

Investigating the influence of institutions, politics, organizations, and governance on the COVID-19 response in British Columbia, Canada: a jurisdictional case study protocol.

BACKGROUND: Research on public health responses to COVID-19 globally has largely focused on understanding the virus' epidemiology, identifying interventions to curb transmission, and assessing the impact of interventions on outcomes. Only recently have studies begun to situate their findings within the institutional, political, or organizational contexts of jurisdictions. Within British Columbia (BC), Canada, the COVID-19 response in early 2020 was deemed highly coordinated and effective overall; however, little is understood as to how these upstream factors influenced policy decisions. METHODS: Using a conceptual framework we developed, we are conducting a multidisciplinary jurisdictional case study to explore the influence of institutional (I), political (P), organizational (O), and governance (G) factors on BC's COVID-19 public health response in 2020-2021. A document review (e.g. policy documents, media reports) is being used to (1) characterize relevant institutional and political factors in BC, (2) identify key policy decisions in BC's epidemic progression, (3) create an organizational map of BC's public health system structure, and (4) identify key informants for interviews. Quantitative data (e.g. COVID-19 case, hospitalization, death counts) from publicly accessible sources will be used to construct BC's epidemic curve. Key informant interviews (n = 15-20) will explore governance processes in the COVID-19 response and triangulate data from prior procedures. Qualitative data will be analysed using a hybrid deductive-inductive coding approach and framework analysis. By integrating all of the data streams, our aim is to explore decision-making processes, identify how IPOG factors influenced policy decisions, and underscore implications for decision-making in public health crises in the BC context and elsewhere. Knowledge users within the jurisdiction will be consulted to construct recommendations for future planning and preparedness. DISCUSSION: As the COVID-19 pandemic evolves, governments have initiated retrospective examinations of their policies to identify lessons learned. Our conceptual framework articulates how interrelations between IPOG contextual factors might be applied to such analysis. Through this jurisdictional case study, we aim to contribute findings to strengthen governmental responses and improve preparedness for future health crises. This protocol can be adapted to and applied in other jurisdictions, across subnational jurisdictions, and internationally.

Exploring the Contributions of Combined Model Regional Medical Education Campuses to the Physician Workforce.

PURPOSE: Physician shortages and maldistribution, particularly within family medicine, have led many medical schools worldwide to create regional medical campuses (RMCs) for clerkship training. However, Canadian medical schools have developed a number of RMCs in which all years of training (i.e., a combined model that includes both preclerkship and clinical training) are provided geographically separate from the main campus. This study addresses the question: Are combined model RMC graduates more likely to enter postgraduate training in family medicine and rural-focused programs relative to main campus graduates? METHOD: The authors used a quasi-experimental research design and analyzed 2006-2016 data from the Canadian Resident Matching Service (CaRMS). Graduating students (N = 26,525) from 16 Canadian medical schools who applied for the CaRMS match in their year of medical school graduation were eligible for inclusion. The proportions of graduates who matched to postgraduate training in (1) family medicine and (2) rural-focused programs were compared for combined model RMCs and main campuses. RESULTS: Of RMC graduates, 48.4% matched to family medicine (95% confidence interval [CI] = 46.1-50.7) compared with 37.1% of main campus graduates (95% CI = 36.5-37.7; P < .001). Of RMC graduates, 23.9% matched to rural-focused training programs (95% CI = 21.8-25.9) compared with 10.4% of main campus graduates (95% CI = 10.0-10.8; P < .001). Subanalyses ruled out a variety of potentially confounding variables. CONCLUSIONS: Combined model RMCs, in which all years of training take place away from the medical school's main campus, are associated with greater proportions of medical students entering family medicine postgraduate training and rural-focused training programs. These findings should encourage policymakers, health services agencies, and medical schools to continue seeking complements to academic medical center-based medical education.

Pedagogical considerations for the teaching of evaluation.

Pedagogy and andragogy refer to the philosophical and empirical assumptions that instructors make about what and how people learn. These assumptions guide much of the subsequent instructional design process, including learning objectives, learning experiences, assessment techniques, and more. Most of the existing literature in evaluator education is descriptive in nature, and there has been limited attention to research on pedagogy specific to evaluation or identification of effective practices for teaching evaluation. As a result, we know very little about the theoretical or practical pedagogy of evaluation. As a first step in understanding this pedagogy, this article first synthesizes relevant concepts, principles of learning, and models of instructional design principles of learning developed in the field of education. The authors then offer case examples of how these ideas, principles, models, and pedagogies apply to five evaluation-specific courses.

Evaluating the Quality of Health Professions Learning Environments: Development and Validation of the Health Education Learning Environment Survey (HELES).

The learning environment can be broadly conceptualized as the physical, social, and psychological context in which learning and socialization takes place. While there is now an expectation that health professions education programs should monitor the quality of their learning environment, existing measures have been criticized for lacking a theoretical foundation and sufficient validity evidence. Guided by Moos's learning environment framework, this study developed and preliminarily validated a global measure of the learning environment. Three pilot tests, conducted on 1,040 undergraduate medical students, refined the measure into the 35-item Health Education Learning Environment Survey (HELES), which consists of six subscales: peer relationships, faculty relationships, work-life balance, clinical skills development, expectations, and educational setting and resources. A final validation study conducted on another sample of 347 medical students confirmed its factor structure and examined its reliability and relation of the HELES to the Medical School Learning Environment Survey (MSLES). Subscale reliabilities ranged from .78 to .89. The HELES correlated with the MSLES at .79. These results indicate that the HELES can provide a valid and reliable assessment of the learning environment of medical students and, as such, can be used to inform accreditation and program planning in health professions programs.

The regional medical campus model and rural family medicine practice in British Columbia: a retrospective longitudinal cohort study.

BACKGROUND: Regional medical campuses have been implemented across North America to address gaps in the physician workforce. We report findings from a study that examined the association between a combined model of regional medical campuses and students' decision to enter rural family medicine practice. METHODS: In 2004, the University of British Columbia added 2 regional medical campuses, 1 in a large population centre in a rural and coastal context and 1 in a medium-sized population centre in an isolated northern and rural context. Data were extracted from the University of British Columbia's Medical Education Database. Multivariable logistic regression examined the relationship of age, sex, rural background and campus location to students' choice of rural family medicine practice. RESULTS: There was an association between campus location and choice of family medicine versus other specialties. A rural background (odds ratio [OR] 2.59, 95% confidence interval [CI] 1.08-6.21) and training at either of the 2 regional medical campuses (OR 3.24, 95% CI 1.19-8.83 and OR 5.38, 95% CI 2.24-12.91) predicted rural family practice. INTERPRETATION: Choosing to practise family medicine in a rural location was associated with having a rural background and having trained at a regional medical campus. These early results suggest that a combined regional campus model in medical education contributes to the rural family practice workforce.

Death by Suicide among Canadian Medical Students: A National Survey-Based Study.

OBJECTIVE: To estimate a rate of death by suicide in the Canadian medical student population and examine the prevalence of institutional response policies for suicide. METHODS: A survey was sent to all 17 Canadian medical undergraduate programs (MDUPs) to collect information on deaths by suicide over the past 10 years. In the case of a reported suicide, basic demographic data was collected. Respondents were asked to indicate whether internal statistics or response policies for suicide existed at their MDUP. RESULTS: Responses were obtained from 16 of 17 (94%) MDUPs. Six suicides (50% female) were reported over the ten-year period from 2006 to 2016. The estimated cause-specific mortality rate was 5.9-8.7/100,000 medical students/year. There were seven (44%) MDUPs that kept statistics on student deaths including suicides and 10 (63%) reported having policies or guidelines regarding what to do in the event of a suicide. CONCLUSIONS: Our estimated suicide rate falls within previously reported rates in medical students. While this may be lower than the national rate for Canadians between the ages of 20-30 years old, any suicide in the medical student community must be an impetus for national dialogue and further study. A strategy is needed to better define the prevalence, risk factors for and impact of medical student suicide in Canada.

The home food environment and associations with dietary intake among adolescents presenting for a lifestyle modification intervention.

BACKGROUND: The home food environment may be an important target for addressing adolescent obesity. The aim of this study was to investigate associations between aspects of the home food environment and the diets of adolescents who present for obesity treatment. METHODS: Cross-sectional baseline data were collected from 167 overweight/obese adolescent-parent pairs participating in an e-health lifestyle modification intervention. Adolescent intake of specific foods (fruit and vegetables, total fat, sugar-sweetened beverages, desserts/treats, and snacking occasions) was assessed by three 24-h dietary recalls, while household factors were collected from adolescent and parent questionnaires. Structural Equation Modeling, controlling for relevant covariates, was used to examine the relationship between adolescent diet and the following household factors: parent modeling, parenting style, family meal practices, and home food/beverage availability. RESULTS: Findings reveal that few characteristics of the home food environment were associated with adolescent dietary intake. Greater home availability of high-fat foods was moderately associated with adolescent snack intake (ß = 0.27, p < .001). Associations with fruit/vegetables and fat intake were small and some were in unexpected directions. Parent modeling of healthful food choices and healthier family meal practices were associated with lower availability of high-fat foods and treats in the home, but were not directly associated with adolescent diets. CONCLUSIONS: Parent modeling of healthy foods and positive mealtime routines might contribute to the healthfulness of foods offered in the homes of adolescents who are overweight/obese. Additional research is needed to better characterize the complex aspects of the household environment that influence adolescent diet.

Readiness for Residency: A Survey to Evaluate Undergraduate Medical Education Programs.

BACKGROUND: Health professions programs continue to search for meaningful and efficient ways to evaluate the quality of education they provide and support ongoing program improvement. Despite flaws inherent in self-assessment, recent research suggests that aggregated self-assessments reliably rank aspects of competence attained during preclerkship MD training. Given the novelty of those observations, the purpose of this study was to test their generalizability by evaluating an MD program as a whole. METHOD: The Readiness for Residency Survey (RfR) was developed and aligned with the published Readiness for Clerkship Survey (RfC), but focused on the competencies expected to be achieved at graduation. The RfC and RfR were administered electronically four months after the start of clerkship and six months after the start of residency, respectively. Generalizability and decision studies examined the extent to which specific competencies were achieved relative to one another. RESULTS: The reliability of scores assigned by a single resident was G = 0.32. However, a reliability of G = 0.80 could be obtained by averaging over as few as nine residents. Whereas highly rated competencies in the RfC resided within the CanMEDS domains of professional, communicator, and collaborator, five additional medical expert competencies emerged as strengths when the program was evaluated after completion by residents. CONCLUSIONS: Aggregated resident self-assessments obtained using the RfR reliably differentiate aspects of competence attained over four years of undergraduate training. The RfR and RfC together can be used as evaluation tools to identify areas of strength and weakness in an undergraduate medical education program.

A qualitative study exploring how school and community environments shape the food choices of adolescents with overweight/obesity.

This study explored perceived barriers and facilitators to healthful eating in schools and communities among overweight teens who completed an E-health intervention. Twenty-two teens were recruited to a photovoice study and asked to take pictures of things that made it easier or harder to make healthful food choices at school and in their community. Digital photographs were reviewed using semi-structured interviews. Transcribed audio-recordings were analyzed using constant comparative analysis. Similar themes emerged from the school and community environments with food/beverage availability emerging most frequently, followed by peer influence, accessibility/convenience, price, classroom practices, marketing and online influences. Teens described an obesity-promoting environment and perceived very limited healthful options. Policy-driven environmental changes as well as strategies that help teens navigate food choices in their schools and communities are needed to support healthful eating.

Experiences of overweight/obese adolescents in navigating their home food environment.

OBJECTIVE: To explore perceived factors that impede or facilitate healthful eating within the home environment among overweight/obese adolescents. DESIGN: In the present qualitative photovoice study, participants were instructed to take photographs of things that made it easier or harder to make healthful food choices at home. Digital photographs were reviewed and semi-structured interviews were conducted to promote discussion of the photographs. Data were analysed using constant comparative analysis. SETTING: Vancouver, Canada, in 2012-2013. SUBJECTS: Twenty-two overweight/obese adolescents who completed a family-based lifestyle modification intervention. RESULTS: The mean age of participants was 14 (sd 1.9) years, 77% were female and their mean BMI Z-score was 2.4 (sd 0.6). Adolescents talked about six aspects of the home environment that influenced their eating habits (in order of frequency): home cooking, availability and accessibility of foods/beverages, parenting practices, family modelling, celebrations and screen use/studying. In general, homes with availability of less healthful foods, where family members also liked to eat less healthful foods and where healthier foods were less abundant or inaccessible were described as barriers to healthful eating. Special occasions and time spent studying or in front of the screen were also conducive to less healthful food choices. Home cooked meals supported adolescents in making healthier food choices, while specific parenting strategies such as encouragement and restriction were helpful for some adolescents. CONCLUSIONS: Adolescents struggled to make healthful choices in their home environment, but highlighted parenting strategies that were supportive. Targeting the home food environment is important to enable healthier food choices among overweight/obese adolescents.

Parent-child associations in selected food group and nutrient intakes among overweight and obese adolescents.

Few studies have compared parent-child dietary intake among adolescents who are overweight or obese. The purpose of our study was to determine the relationship between parent-teen intake of selected dietary components among this sample. Baseline data from 165 parent and adolescent (aged 11 to 16 years) pairs who presented for a lifestyle behavior modification intervention were collected between 2010 and 2012. Parent and adolescent dietary intake (servings of fruits and vegetables [F/V]; grams of sugar; and percent energy from total fat, saturated fat, dessert/treats, sugar-sweetened beverages, and snacks) was assessed using web-based 24-hour dietary recalls. Multivariable linear and negative binomial regression models identified associations between parent and child dietary intake adjusting for relevant covariates. A large proportion of adolescents and parents did not meet dietary recommendations for F/V, total fat, and saturated fat. Parent-adolescent intake of F/V, total fat, saturated fat, sugar, sugar-sweetened beverages, and snacks were positively associated (r=0.19 to 0.37). No relationship was observed for dessert/treats. In multivariate models, significant interaction effects suggest that the parent-child association in diet was weaker for fat intake among parents with higher educational attainment (b=-.31; P<0.05) and for snacking among adolescent boys (b=-.30; P<.05). Parent intake of several dietary components important for good health, and related to obesity, was associated with adolescent intake. Helping parents improve their diet may promote improvements in their adolescent's diet and is a potential target for interventions designed to increase healthy eating among adolescents.

Impact of a regional distributed medical education program on an underserved community: perceptions of community leaders.

PURPOSE: To describe community leaders' perceptions regarding the impact of a fully distributed undergraduate medical education program on a small, medically underserved host community. METHOD: The authors conducted semistructured interviews in 2007 with 23 community leaders representing, collectively, the education, health, economic, media, and political sectors. They reinterviewed six participants from a pilot study (2005) and recruited new participants using purposeful and snowball sampling. The authors employed analytic induction to organize content thematically, using the sectors as a framework, and they used open coding to identify new themes. The authors reanalyzed transcripts to identify program outcomes (e.g., increased research capacity) and construct a list of quantifiable indicators (e.g., number of grants and publications). RESULTS: Participants reported their perspectives on the current and anticipated impact of the program on education, health services, the economy, media, and politics. Perceptions of impact were overwhelmingly positive (e.g., increased physician recruitment), though some were negative (e.g., strains on health resources). The authors identified new outcomes and confirmed outcomes described in 2005. They identified 16 quantifiable indicators of impact, which they judged to be plausible and measureable. CONCLUSIONS: Participants perceive that the regional undergraduate medical education program in their community has broad, local impacts. Findings suggest that early observed outcomes have been maintained and may be expanding. Results may be applicable to medical education programs with distributed or regional sites in similar rural, remote, and/or underserved regions. The areas of impact, outcomes, and quantifiable indicators identified will be of interest to future researchers and evaluators.

School and community predictors of smoking: a longitudinal study of Canadian high schools.

OBJECTIVES: We identified the most effective mix of school-based policies, programs, and regional environments associated with low school smoking rates in a cohort of Canadian high schools over time. METHODS: We collected a comprehensive set of student, school, and community data from a national cohort of 51 high schools in 2004 and 2007. Hierarchical linear modeling was used to predict school and community characteristics associated with school smoking prevalence. RESULTS: Between 2004 and 2007, smoking prevalence decreased from 13.3% to 10.7% in cohort schools. Predictors of lower school smoking prevalence included both school characteristics related to prevention programming and community characteristics, including higher cigarette prices, a greater proportion of immigrants, higher education levels, and lower median household income. CONCLUSIONS: Effective approaches to reduce adolescent smoking will require interventions that focus on multiple factors. In particular, prevention programming and high pricing for cigarettes sold near schools may contribute to lower school smoking rates, and these factors are amenable to change. A sustained focus on smoking prevention is needed to maintain low levels of adolescent smoking.

The readiness for clerkship survey: can self-assessment data be used to evaluate program effectiveness?

PURPOSE: To examine whether or not aggregated self-assessment data of clerkship readiness can provide meaningful sources of information to evaluate the effectiveness of an educational program. METHOD: The 39-item Readiness for Clerkship survey was developed during academic year 2009-2010 using several key competence documents and expert review. The survey was completed by two cohorts of students (179 from the class of 2011 in February 2010, 171 from the class of 2012 in November 2010) and of clinical preceptors (384 for class of 2011 preceptors, 419 for class of 2012 preceptors). Descriptive statistics, Pearson correlations coefficients, ANOVA, and generalizability and decision studies were used to determine whether ratings could differentiate between different aspects of a training program. RESULTS: When self-assessments were aggregated across students, their judgments aligned very well with those of faculty raters. The correlation of average scores, calculated for each item between faculty and students, was r=0.88 for 2011 and r=0.91 for 2012. This was only slightly lower than the near-perfect correlations of item averages within groups across successive years (r=0.99 for faculty; r=0.98 for students). Generalizability and decision analyses revealed that one can achieve interrater reliability in this domain with fewer students (9-21) than faculty (26-45). CONCLUSIONS: These results provide evidence that, when aggregated, student self-assessment data from the Readiness for Clerkship Survey provide valid data for use in program evaluation that align well with an external standard.

Exploring the role of social capital in supporting a regional medical education campus.

INTRODUCTION: To help address physician shortages in the underserved community of Prince George, Canada, the University of British Columbia (UBC) and various partners created the Northern Medical Program (NMP), a regional distributed site of UBC's medical doctor undergraduate program. Early research on the impacts of the NMP revealed a high degree of social connectedness. The objective of the present study was to explore the role of social capital in supporting the regional training site and the benefits accrued to a broad range of stakeholders and network partners. METHODS: In this qualitative study, 23 semi-structured interviews were conducted with community leaders in 2007. A descriptive content analysis based on analytic induction technique was employed. Carpiano's Bourdieu-based framework of 'neighbourhood' social capital was adapted to empirically describe how social capital was produced and mobilized within and among networks during the planning and implementation of the NMP. RESULTS: Results from this study reveal that the operation of social capital and the related concept of social cohesion are multifaceted, and that benefits extend in many directions, resulting in somewhat unanticipated benefits for other key stakeholders and network partners of this medical education program. Participants described four aspects of social capital: (i) social cohesion; (ii) social capital resources; (iii) access to social capital; and (iv) outcomes of social capital. CONCLUSIONS: The findings of this study suggest that the partnerships and networks formed in the NMP planning and implementation phases were the foundation for social capital mobilization. The use of Carpiano's spatially-bounded model of social capital was useful in this context because it permitted the characterization of relations and networks of a tight-knit community body. The students, faculty and administrators of the NMP have benefitted greatly from access to the social capital mobilized to make the NMP operational. Taking account of the dynamic and multifaceted operation of social capital helps one move beyond a view of geographic communities as simply containers or sinks of capital investment, and to appreciate the degree to which they may act as a platform for productive network formation and expansion.

Impact of tobacco advertising and promotion on increasing adolescent smoking behaviours.

BACKGROUND: The tobacco industry denies that their marketing is targeted at young nonsmokers, but it seems more probable that tobacco advertising and promotion influences the attitudes of nonsmoking adolescents, and makes them more likely to try smoking. OBJECTIVES: To assess the effects of tobacco advertising and promotion on nonsmoking adolescents' future smoking behaviour. SEARCH STRATEGY: We searched the Cochrane Tobacco Group specialized register, the Cochrane Central Register of Controlled Trials, MEDLINE, the Cochrane Library, Sociological Abstracts, PsycLIT, ERIC, WorldCat, Dissertation Abstracts, ABI Inform and Current Contents to August 2011. SELECTION CRITERIA: We selected longitudinal studies that assessed individuals' smoking behaviour and exposure to advertising, receptivity or attitudes to tobacco advertising, or brand awareness at baseline, and assessed smoking behaviour at follow ups. Participants were adolescents aged 18 or younger who were not regular smokers at baseline. DATA COLLECTION AND ANALYSIS: Studies were prescreened for relevance by one reviewer. Two reviewers independently assessed relevant studies for inclusion. Data were extracted by one reviewer and checked by a second. MAIN RESULTS: Nineteen longitudinal studies that followed up a total of over 29,000 baseline nonsmokers met inclusion criteria. The studies measured exposure or receptivity to advertising and promotion in a variety of ways, including having a favourite advertisement or an index of receptivity based on awareness of advertising and ownership of a promotional item. One study measured the number of tobacco advertisements in magazines read by participants. All studies assessed smoking behaviour change in participants who reported not smoking at baseline. In 18 of the 19 studies the nonsmoking adolescents who were more aware of tobacco advertising or receptive to it, were more likely to have experimented with cigarettes or become smokers at follow up. There was variation in the strength of association, and the degree to which potential confounders were controlled for. AUTHORS' CONCLUSIONS: Longitudinal studies consistently suggest that exposure to tobacco advertising and promotion is associated with the likelihood that adolescents will start to smoke. Based on the strength and specificity of this association, evidence of a dose-response relationship, the consistency of findings across numerous observational studies, temporality of exposure and smoking behaviours observed, as well as the theoretical plausibility regarding the impact of advertising, we conclude that tobacco advertising and promotion increases the likelihood that adolescents will start to smoke.

Nature and nurture in the family physician's choice of practice location.

INTRODUCTION: An understanding of the contextual, professional, and personal factors that affect choice of practice location for physicians is needed to support successful strategies in addressing geographic maldistribution of physicians. This study compared two categories of predictors of family practice location in non-metropolitan areas among undergraduate medical students: individual characteristics (nature), and the rural program component of their training program (nurture). The study aimed to identify factors that predict the location of practice 2 years post-residency training and determine the predictive value of combining nature and nurture variables using administrative data from two undergraduate medical education programs. METHODS: Databases were developed from available administrative sources for a retrospective analysis of two undergraduate medical education programs in Canada: Université de Sherbrooke (UdeS) and University of British Columbia (UBC). Both schools have a strong mandate to evaluate the impact of their programs on physician distribution. The dependent variable was location of practice 2 years after completing postgraduate training in family medicine. Independent variables included individual and program characteristics. Separate analyses were conducted for each program using multiple logistic regression. RESULTS: The nature and nurture variables considered in the models explained only 21% to 27% of the variance in the eventual location of practice of family physician graduates. For UdeS, having an address in a rural/small-town environment at application to medical school (OR=2.61, 95% CI: 1.24-6.06) and for UBC, location of high school in a rural/small town (OR=4.03, 95% CI: 1.05-15.41), both increased the chances of practicing in a non-metropolitan area. For UdeS the nurture variable (ie length of clerkship in a non-metropolitan area) was the most significant predictor (OR=1.14, 95% CI: 1.067-1.22). For both medical schools, adding a single nurture variable to the model using only nature variables significantly increased the amount of variation accounted for in predicting location of practice in non-metropolitan areas. CONCLUSIONS: Aspects of graduates' rural background increase the chances of practicing in a non-metropolitan area. A third-year clerkship experience in a rural area may increase the chances of non-metropolitan practice. Although the total variation predicted by both nature and nurture variables in this study was small, adding a nurture variable significantly improves the prediction of individuals who will practice in a non-metropolitan area. The fact that total variation predicted was small is likely to be due to the limitations of the administrative databases used. Different strategies are being implemented in each university to improve the quality of existing administrative databases, as well as to collect relevant data about intent-to-practice, training characteristics, and the attitudes, beliefs and backgrounds of students.

Evaluation of a violence risk assessment system (the Alert System) for reducing violence in an acute hospital: a before and after study.

OBJECTIVES: To investigate the effectiveness of a risk assessment system in reducing the risk of violence in an acute care hospital in the Canadian province of British Columbia. METHODS: Hospital violence incident rates (number of incidents/100,000 work hours) were calculated and compared pre, during and post implementation of the Alert System, a violence risk assessment system, at one acute care hospital. Poisson regression models were used to examine the effect of the Alert System on hospital-level violent incident rates. Multivariable, conditional logistic regression was used to examine the effect of the Alert System on the individual-level risk of violent incidence using a case-control study. RESULTS: The violent incident rate decreased during the Alert System implementation period only, but subsequently returned to pre-implementation levels. In the case-control analyses, the Alert flag was associated with an increased risk for a patient violent incident (odds ratio=7.74, 95% CI=4.81-12.47). CONCLUSIONS: Although useful at identifying violent patients, the Alert System even though offered in conjunction with violence prevention training, does not appear to provide the resources or procedures needed by healthcare workers to prevent a patient from progressing to a violent incident once flagged. Violence in healthcare should be studied and prevented using a multifaceted approach.
