Trends in concussions at Ontario schools prior to and subsequent to the introduction of a concussion policy - an analysis of the Canadian hospitals injury reporting and prevention program from 2009 to 2016
Background: Concussion is a preventable injury that can have long-term health consequences for children and youth. In Ontario, the Policy/Program Memorandum # 158 (PPM) was introduced by the Ministry of Education of Ontario in March 2014. The PPM’s main purpose is to require each school board in the province to create and implement a concussion policy. The purpose of this paper is to examine trends in school-based concussions prior to and subsequent to the introduction of the PPM.
Methods: This report examined emergency department (ED) visits in 5 Ontario hospitals that are part of the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP), and compared trends over time in diagnosed concussions, and suspected concussions identified as “other head injury” in children and youth aged 4–18.
Results: From 2009 to 2016 study years, there were 21,094 suspected concussions, including 8934 diagnosed concussions in youth aged 4–18. The average number of diagnosed concussions in the 5 years before the PPM was 89 concussions/month, compared to approximately 117 concussions per month after; a 30% increase in the monthly rate of concussions presenting to the ED. The total number of concussion or head injury-related ED visits remained relatively unchanged but the proportion of diagnosed concussions rose from 31% in 2009 to 53% in 2016. The proportion of diagnosed concussions in females also increased from 38% in 2013 to 46% in 2016. The percent of all diagnosed concussions occurring at schools increased throughout the study reaching almost 50% in 2016 with most injuries taking place at the playground (24%), gymnasium (22%) or sports field (20%).
Conclusions: The introduction of the PPM may have contributed to a general increase in concussion awareness and an improvement in concussion identification at the school level in children and youth aged 4–18.

On-ice measures of external load in relation to match outcome in elite female ice hockey
The aim of this study is to investigate the differences between select on-ice measures using inertial movement sensors based on match outcome, and to determine changes in player movements across three periods of play. Data were collected during one season of competition in elite female ice hockey players (N = 20). Two-factor mixed effects ANOVAs for each skating position were performed to investigate the differences in match outcome, as well as differences in external load measures during the course of a match. For match outcome, there was a small difference for forwards in explosive ratio (p = 0.02, ES = 0.26) and percentage high force strides (p = 0.04, ES = 0.50). When viewed across three periods of a match, moderate differences were found in skating load (p = 0.01, ES = 0.75), explosive efforts (p = 0.04, ES = 0.63), and explosive ratio (p = 0.002, ES = 0.87) for forwards, and in PlayerLoad (p = 0.01, ES = 0.70), explosive efforts (p = 0.04, ES = 0.63), and explosive ratio (p = 0.01, ES = 0.70) for defense. When examining the relevance to match outcome, external load measures associated with intensity appear to be an important factor among forwards. These results may be helpful for coaches and sport scientists when making decisions pertaining to training and competition strategies.York University Librarie
Epidemiology of sports-related injuries in children and youth presenting to Canadian emergency departments from 2007–2010
BACKGROUND: Although injuries related to sports and recreation represent a significant burden to children and youth, few studies have examined the descriptive epidemiology of sports-related injury since 2005, and some sports such as ringette have not been evaluated to date. The primary purpose of this study was to provide the descriptive epidemiology of sports-related injuries treated in emergency departments for children and youth aged 5 – 19. METHODS: A retrospective data analysis was performed using data from the Canadian Hospitals Injury Reporting and Prevention Program [CHIRPP] from fiscal years (April – March) 2007/08 to 2009/10. CHIRPP is a computerized information system designed by the Public Health Agency of Canada that collects information about injuries to people evaluated in emergency departments across 11 pediatric hospitals and 5 general hospitals in Canada. Thirteen sports or activities were analyzed (baseball, basketball, cycling, football, ice hockey, lacrosse, ringette, rugby, skiing, sledding, snowboarding, soccer, and volleyball). Descriptive statistics, including frequency by sport, age and sex, as well as the percent of concussions within each sport were calculated. RESULTS: Out of a total of 56, 691 reported sports and recreational injuries, soccer accounted for the largest proportion of injuries with 11,941 reported cases over the 3 year time period. Of these, approximately 30% were fractures. The 10 – 14 year age group reported the greatest proportion of injuries in 10 out of the 13 sports analyzed. In addition, males reported a greater number of overall injuries than females in 11 out of the 13 sports analyzed. The largest percentage of concussions was reported in ringette; these injuries accounted for 17.1% of overall injuries within this sport. CONCLUSIONS: Injury prevention programs in Canada should focus on improving evidence-based programs to reduce the burden of injuries in all sports
Training approaches, preferences and outcomes in manufacturing SMEs
Unlike previous studies which concentrate only on formal training, this is a detailed
empirical analysis of the influence of formal and informal training on performance in
manufacturing SMEs. Findings indicate that, while SME managers may prefer
informal approaches, formal training is a targeted activity that contributes more
significantly to performance than informal training. However, the approach and
influence of training is dependent on contingent factors. A model is proposed for a
detailed study of these contingent factors using a multivariate statistical analysis.
Findings also suggest that policy support for SMEs should be idiosyncratic and
requires a detailed understanding of context
Association Between First Attempt Buffalo Concussion Treadmill Test and Days to Recovery in 855 Children With Sport-Related Concussion: A Historical Cohort Study and Prognostic Factors Analysis
OBJECTIVE: Little is known about the prognostic value of the Buffalo Concussion Treadmill Test (BCTT) after the acute phase of sport-related concussion (SRC). We examined the added prognostic value of the BCTT performed 10 to 21 days after SRC in children, in addition to participant, injury, and clinical process characteristics on days to recovery.
DESIGN: Historical clinical cohort study.
SETTING:
Network of approximately 150 Canadian multidisciplinary primary-care clinics.
PARTICIPANTS: 855 children (mean age 14 years, range 6-17 years, 44% female) who presented between January 2016, and April 2019 with SRC.
ASSESSMENT OF RISK FACTORS: Participant, injury, and clinical process characteristics, with focus on BCTT exercise intolerance assessed 10 to 21 days after injury.
OUTCOME: Days to clinical recovery.
RESULTS: Children who were exercise intolerant experienced an increase of 13 days to recovery (95% CI, 9-18 days). Each additional day between SRC and first BCTT was associated with a recovery delay of 1 day (95% CI, 1-2 days), and prior history of concussion was associated with a recovery delay of 3 days (95% CI, 1-5 days). Participant, injury, and clinical process characteristics, and the first attempt BCTT result explained 11% of the variation in recovery time, with 4% accounted for by the BCTT.
CONCLUSION: Exercise-intolerance assessed 10 to 21 days after SRC was associated with delayed recovery. However, this was not a strong prognostic factor for days to recovery

Drive time to cardiac rehabilitation: at what point does it affect utilization?
<p>Abstract</p> <p>Background</p> <p>A 30 minute drive time threshold has often been cited as indicative of accessible health services. Cardiac rehabilitation (CR) is a chronic disease management program designed to enhance and maintain cardiovascular health, and geographic barriers to utilization are often cited. The purpose of this study was to empirically test the drive time threshold for CR utilization.</p> <p>Methods</p> <p>A prospective study, using a multi-level design of coronary artery disease outpatients nested within 97 cardiologists. Participants completed a baseline sociodemographic survey, and reported CR referral, enrollment and participation in a second survey 9 months later. CR utilization was verified with CR sites. Geographic information systems were used to generate drive times at 60, 80 and 100% of the speed limit to the closest CR site from participants' homes, to take into consideration various traffic conditions. Bivariate analysis was used to test for differences in CR referral, enrollment and degree of participation by drive time. Logistic regression was used to test drive time increments where significant differences were found.</p> <p>Results</p> <p>Drive times were generated for 1209 outpatients. Overall, CR referral was verified for 523 (43.3%) outpatients, with verified enrollment for 444 (36.7%) participating in a mean of 86.4 ± 25.7% of prescribed sessions. There were significant differences in CR referral and enrollment by drive time (ps < .01), but not degree of participation. Logistic regression analysis (ps < .001) revealed that the drive time threshold at 80% of the posted speed limit for physician referral may be 60 minutes (OR = .26, 95% CI: 0.13-0.55), and the threshold for patient CR enrollment may also be 60 minutes (OR = .11, 95% CI: 0.04-0.33).</p> <p>Conclusions</p> <p>Physicians may be taking geography into consideration when referring patients to CR. Empirical consideration also reveals that patients are significantly less likely to enroll in CR where they must drive 60 minutes or more to the closest program. Once enrolled, distance has no significant effect on degree of participation.</p
Research Data Management in the Atlantic Provinces
Research Data Management (RDM) is becoming an increasingly important issue for post-secondary institutions. The Tri-Agencies (SSHRC, NSERC, CIHR) are expected to release a new policy that will stipulate that institutions have an institutional strategy for dealing with research data. Part of the responsibility will lie with researchers and the management of their research data.
Three Atlantic universities are aiming to discover how researchers are storing, using and sharing their data through administering a survey using an instrument that has been used at many Canadian universities. Surveys will be administered in Winter 2019. Data from the surveys will be analyzed separately by each institution and may be combined to identify commonalities and possibilities for collaboration in the region.
The results of these surveys will help librarians, IT specialists, data managers, and others interested in data management to understand current practices and attitudes. The results will also be used to contribute of the development of RDM services and resources across Atlantic post-secondary institutions with the aim of being prepared for the Tri-Agency policy once it comes into effect

Geographic Issues in Cardiac Rehabilitation Utilization: A Narrative Review.
Objective: The purpose of this study was to review the current evidence regarding the relationship between geographic indicators and cardiac rehabilitation (CR) utilization among coronary heart disease (CHD) patients.
Results: Seventeen articles were identified for inclusion, where nine studies assessed rurality, 10 studies assessed travel time / distance, and two of these studies assessed both. Nine of the 17 studies (52.9%) showed a significant negative relationship between geographic barrier and CR use. Four of the 17 studies (23.5%) showed a null relationship, while four studies (23.5%) showed mixed findings. Inconsistent findings identified appeared to be related to restricted geographic range, regional density, and socioeconomic status.
Conclusions: Overall, 52.9% of the identified studies reported a significant negative relationship between geographic indicators and CR utilization. This relationship appeared to be particularly consistent in North American and Australian settings, but somewhat less so in the United Kingdom where there is greater population density and availability of public transport
