Evidence based prevention of acute injuries during physical exercise in a WHO safe community

Community-level football injury epidemiology: traumatic injuries treated at Swedish emergency medical facilities

Background

Despite the popularity of the sport, few studies have investigated community-level football injury patterns. This study examines football injuries treated at emergency medical facilities using data from three Swedish counties.

Methods

An open-cohort design was used based on residents aged 0-59 years in three Swedish counties (pop. 645 520). Data were collected from emergency medical facilities in the study counties between 1 January 2007 and 31 December 2010. Injury frequencies and proportions for age groups stratified by sex were calculated with 95% confidence intervals (95% CIs) and displayed per diagnostic group and body location.

Results

Each year, more than 1/200 person aged 0-59 years sustained at least one injury during football play that required emergency medical care. The highest injury incidence was observed among adolescent boys [2009 injuries per 100 000 population years (95% CI 1914-2108)] and adolescent girls [1413 injuries per 100 000 population years (95% CI 1333-1498)]. For female adolescents and adults, knee joint/ligament injury was the outstanding injury type (20% in ages 13-17 years and 34% in ages 18-29 years). For children aged 7-12 years, more than half of the treated injuries involved the upper extremity; fractures constituted about one-third of these injuries.

Conclusions

One of every 200 residents aged 0-59 years in typical Swedish counties each year sustained a traumatic football injury that required treatment in emergency healthcare. Further research on community-level patterns of overuse syndromes sustained by participation in football play is warranted.

Intervention Strategies Used in Sport Injury Prevention Studies: A Systematic Review Identifying Studies Applying the Haddon Matrix

BACKGROUND

Prevention of sport injuries is crucial to maximise the health and societal benefits of a physically active lifestyle. To strengthen the translation and implementation of the available evidence base on effective preventive measures, a range of potentially relevant strategies should be considered.

OBJECTIVE

Our aim was to identify and categorise intervention strategies for the prevention of acute sport injuries evaluated in the scientific literature, applying the Haddon matrix, and identify potential knowledge gaps.

METHODS

Five electronic databases were searched (PubMed, EMBASE, SPORTDiscus, CINAHL, Cochrane) for studies that evaluated the effect of interventions on the occurrence of acute sport injuries. Studies were required to include a control group/condition, prospective data collection, and a quantitative injury outcome measure.

RESULTS

A total of 155 studies were included, mostly randomised controlled trials (43%). The majority of studies (55%) focussed on strategies requiring a behavioural change on the part of athletes. Studies predominantly evaluated the preventive effect of various training programmes targeted at the 'pre-event' phase (n = 73) and the use of equipment to avoid injury in the 'event phase' (n = 29). A limited number of studies evaluated the preventive effect of strategies geared at rules and regulations (n = 14), and contextual modifications (n = 18). Studies specifically aimed at preventing re-injuries were a minority (n = 8), and were mostly related to ankle sprains (n = 5).

CONCLUSIONS

Valuable insight into the extent of the evidence base of sport injury prevention studies was obtained for 20 potential intervention strategies. This approach can be used to monitor potential gaps in the knowledge base on sport injury prevention.

The 'WHO Safe Communities' model for the prevention of injury in whole populations

BACKGROUND

The World Health Organization (WHO) 'safe communities' approach to injury prevention has been embraced around the world as a model for co-ordinating community efforts to enhance safety and reduce injury. Approximately 150 communities throughout the world have formal 'Safe Communities' designation. It is of public health interest to determine to what degree the model is successful, and whether it reduces injury rates. This Cochrane Review is an update of a previous published version.

OBJECTIVES

To determine the effectiveness of the WHO Safe Communities model to prevent injury in whole populations.

SEARCH STRATEGY

Our search included CENTRAL, MEDLINE and EMBASE, PsycINFO, ISI Web of Science: Social Sciences Citation Index (SSCI) and ZETOC. We handsearched selected journals and contacted key people from each WHO Safe Community. The last search was December 2008.

SELECTION CRITERIA

Two authors independently screened studies for inclusion. Included studies were those conducted within a WHO Safe Community that reported changes in population injury rates within the community compared to a control community.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data. Meta-analysis was not appropriate due to the heterogeneity of the included studies.

MAIN RESULTS

We included evaluations for 21 communities from five countries in two geographical regions in the world: Austria, Sweden and Norway, and Australia and New Zealand. Although positive results were reported for some communities, there was no consistent relationship between being a WHO designated Safe Community and subsequent changes in observed injury rates.

AUTHORS' CONCLUSIONS

There is marked inconsistency in the results of the studies included in this systematic review. While the frequency of injury in some study communities did reduce following their designation as a WHO Safe Community, there remains insufficient evidence from which to draw definitive conclusions regarding the effectiveness of the model.The lack of consistency in results may be due to the heterogeneity of the approaches to implementing the model, varying efficacy of activities and strategies, varying intensity of implementation and methodological limitations in evaluations. While all communities included in the review fulfilled the WHO Safe Community criteria, these criteria were too general to prescribe a standardised programme of activity or evaluation methodology.Adequate documentation describing how various Safe Communities implemented the model was limited, making it unclear which factors affected success. Where a reduction in injury rates was not reported, lack of information makes it difficult to distinguish whether this was due to problems with the model or with the way in which it was implemented.

From sports injury prevention to safety promotion in sports

Every fifth unintentional injury treated at a healthcare facility in the industrialised part of the world is associated with sports or physical exercise. This article reviews the literature regarding the theoretical and practical underpinnings for community-based sports safety promotion, including both professional and recreational sports. While injury prevention entails the implementation of specific interventions in terms of structural or educational measures, sports safety promotion includes also the antecedent and wider campaigns that are required to succeed with these measures. Comprehensive sports safety promotion programmes thus require that the perspective on the sports injury problem is made broader than consideration of the individual athlete. The results display that involvement in sports safety issues from the sports federations that formulate policies and allocate resources is necessary for coordinated implementation of programme actions. The authorities responsible for sports facilities and legislations in the civil society also need to be included, because of the fact that they control many of the central safety determinants in the sporting environment. It is concluded that the sports injury problem needs to be addressed in liaison with the leaders of socially defined sports communities and the governments representing geographically defined civic communities, and that the safety-supporting environment in professional sports is underdeveloped compared with other areas of working life.

Patterns of injury associated with routine childhood falls

OBJECTIVE

To identify the pattern of injuries associated with routine childhood falls.

METHODS

Retrospective chart review of patients at most 12 years presenting to a children's hospital emergency department with complaint of a fall. Patients were classified into 3 age groups (<2, 2-4, and 5-12 years) and analyzed for the type of fall and diagnosis.

RESULTS

Seven hundred eighty-seven patients were enrolled. Mean age was 5.7 years. Fifty-six percent were boys. The types of falls reported were categorized as a fall down steps, from patient's own height, from an object, and other. In all 3 groups, the most common fall was fall from an object (50%, 50%, and 48%, respectively). There were 91 (12%) patients in the younger-than-2-year-old age group and 235 (30%) in the 2- to 4-year-old age group. Both groups commonly fell from a bed/chair (35% and 25%, respectively). In the youngest group, the most frequent diagnosis was head injury (41%; odds ratio [OR], 5.0; 95% confidence interval [CI], 3.0-8.1). Children ages 5 to 12 years numbered 461 (58%) and most commonly fell from playground equipment (26%) sustaining a fracture (65%; OR, 3.1; 95% CI, 2.3-4.3). Of these, 77% were in the upper extremity (arm fracture; OR, 41; 95% CI, 22-79).

CONCLUSIONS

In children who presented to a children's hospital emergency department with a fall, fall from an object was the most common type. Those younger than 2 years, most commonly fell from a bed/chair and sustained head injury. Children 5 to 12 years old were likely to fall from playground equipment and fracture their arm. These findings may be helpful to clinicians who evaluate routine childhood falls.

Evaluation of community-based injury prevention programmes: methodological issues and challenges

The evaluation of comprehensive community-based injury prevention programmes is complex and poses many methodological challenges. There is little consensus in contemporary literature about the most appropriate methods of evaluating these programmes. This study employed a systematic literature review to examine evaluations of 16 community-based injury prevention programmes with regard to key methodological issues and challenges. Three aspects of the evaluated programmes were analysed: assessed elements (context, structure, process, impact, and outcome); study design; and methodological issues addressed. The results showed that context, structure and process assessments were the most neglected aspects of the evaluation studies. The programmes were typically described with minimal discussion of how the context may have influenced the effectiveness. The process (activities) was described rather than evaluated against appropriate standards of comparisons. Impact evaluations adhered more closely to documented guidelines, but half of the evaluations did not include impact variables. Outcome evaluations focused on injury incidence. Most evaluations employed some qualitative methods, but the vast majority of methods used were quantitative. This study indicated that the quasi-experimental study design has become an accepted norm for the evaluation of community-based injury prevention programmes. Most of the evaluations contained explicit details of the methodology used and of the choices related to the methodology. While threats to internal validity were identified in most studies, problems related to external validity and construct validity were largely overlooked by the evaluators.

The 'WHO Safe Communities' model for the prevention of injury in whole populations

BACKGROUND

The safe communities approach has been embraced around the world as a model for coordinating community efforts to enhance safety and reduce injury. Over 80 communities throughout the world have been formally designated as 'Safe Communities' by the World Health Organization. It is of public health interest to determine to what degree the model is successful, and whether its application does indeed reduce injury rates in communities to which it is introduced.

OBJECTIVES

To determine the effectiveness of the Safe Communities model to prevent injury in whole populations, or targeted sub-groups of populations.

SEARCH STRATEGY

The search strategy was based on electronic searches, handsearches of selected journals, snowballing from reference lists of selected publications and contacting a key person from each WHO-designated Safe Community.

SELECTION CRITERIA

Studies were independently screened for inclusion by two reviewers. Included studies were those conducted within a WHO Safe Community that reported changes in population injury rates within the community compared to a control community.

DATA COLLECTION AND ANALYSIS

Data were independently extracted by two reviewers. Meta-analysis was not appropriate, due to the heterogeneity of the included studies.

MAIN RESULTS

Only seven WHO Safe Communities, of more than 80 worldwide, have undertaken controlled evaluations using objective sources of injury data. These communities represent only four countries from two geographical regions in the world: the Scandinavian countries of Sweden and Norway and the Pacific nations of Australia and New Zealand. Safe Communities in Sweden and Norway have resulted in significant reductions in injury rates. The Australian and New Zealand communities have been unable to replicate the same level of success.

AUTHORS' CONCLUSIONS

Evidence suggests the WHO Safe Communities model is effective in reducing injuries in whole populations. However, important methodological limitations exist in all studies from which evidence can be obtained. A lack of reported detail makes it unclear which factors facilitate or hinder a programme's success, and makes uncertain, whether the success of any particular application of the model is necessarily replicable in other communities. In evaluated programmes that did not report significant decreases in injury rates, this lack of information makes it difficult to distinguish between evidence of no effect of the model, or no evidence of effect. The four countries that have evaluated their Safe Communities with a sufficiently rigorous study design have higher economic wealth and health standards and lower injury rates than much of the world. No evaluations were available from other parts of the world, despite the designation of WHO Safe Communities in countries such as South Africa, Bangladesh, China, Vietnam, Canada, UK and USA. Generalisation of results of studies conducted in just four countries, to the international population needs to be done with caution. There is a need for more high-quality, methodologically strong evaluations of the model in a range of diverse communities and detailed reporting of implementation processes.

Injuries in competitive youth bandy: an epidemiological study of a league season

PURPOSE

Bandy, with a century-long tradition in northern Europe, is a winter team-sport similar to ice hockey. To investigate the occurrence of injuries during competitive youth bandy games, injury incidence, injury types, and age-related risks were analyzed for one youth league season.

METHODS

The National Athletic Injury/Illness Reporting System (NAIRS) definition of sports injury was used for the injury registration. All 416 games during the 1999-2000 season in the Swedish southeastern youth bandy league were included in the study. Primary data was collected by a questionnaire and completed by the team coaches after each game. At the end of the season, physician interviews with each team coach were performed to assure that no injuries had been missed as well as to ascertain whether there was any remaining disability.

RESULTS

In total, 2.0 injuries (95% confidence interval 1.2-2.9 injuries) per 1000 player game hours were recorded. Sixty-eight percent of the injuries caused the injured player to be absent from bandy play for more than a week. Collision was the most common cause of injury (36%), and contusion was the most common injury type (41%). The injury incidence in the leagues for older players (Youth 14 -Youth 16) was slightly higher than in the leagues for the younger players (Youth 12 -Youth 13), while participation by under-aged players in games organized for older players led to an almost four-fold increase of injury risk. For severe injuries, the mean rehabilitation time away from bandy practice or competition was 27 d (range 8-56 d).

CONCLUSION

The overall injury incidence during youth bandy games is low, but the injuries that occur cause extensive absences from the only four months long bandy season. From a public health perspective, bandy can be recommended for consideration when physical exercise is to be promoted among school-age children in countries with a winter climate.
