- Description: Objective: To compare Orchard Sports Injury Classification System (OSICS-10) sports medicine diagnoses assigned by a clinical and non-clinical coder. Design: Assessment of intercoder agreement. Setting: Community Australian football. Participants: 1082 standardised injury surveillance records. Main outcome measurements: Direct comparison of the four-character hierarchical OSICS-10 codes assigned by two independent coders (a sports physician and an epidemiologist). Adjudication by a third coder (biomechanist). Results: The coders agreed on the first character 95% of the time and on the first two characters 86% of the time. They assigned the same four-digit OSICS-10 code for only 46% of the 1082 injuries. The majority of disagreements occurred for the third character; 85% were because one coder assigned a non-specific 'X' code. The sports physician code was deemed correct in 53% of cases and the epidemiologist in 44%. Reasons for disagreement included the physician not using all of the collected information and the epidemiologist lacking specific anatomical knowledge. Conclusions: Sports injury research requires accurate identification and classification of specific injuries and this study found an overall high level of agreement in coding according to OSICS-10. The fact that the majority of the disagreements occurred for the third OSICS character highlights the fact that increasing complexity and diagnostic specificity in injury coding can result in a loss of reliability and demands a high level of anatomical knowledge. Injury report form details need to reflect this level of complexity and data management teams need to include a broad range of expertise. Copyright Article author (or their employer) 2012.

- Description:
BACKGROUND:It is well known that the condition and type of sporting ground influences the risk of sports injury. However, the lack of evidence on the relationship between subjective and objective sporting ground condition assessments in sports injury aetiology studies has implications for the development of effective injury prevention strategies. This paper aims to examine concordance between subjectively rated and objective ground hardness and moisture measurements to inform data collection methods for future sports injury aetiology studies. METHODS:Subjective, observational assessments of ground hardness and soil moisture were recorded on 36 occasions during an Australian football season using two four-point scales of 'very soft' to 'very hard' and 'very wet' to 'very dry', respectively. Independent, objectively measured hardness and soil moisture were also undertaken at nine locations on the same grounds. The maximum and minimum ground values and the computed average of ground hardness and soil moisture were analysed. Somer's d statistic was calculated to measure the level of concordance between the subjective and objective measures. RESULTS:A significant, moderate to substantial level of agreement was found between the subjective ratings and the average objective hardness values (d = 0.467, p <0.001), but there was perfect agreement on just less than half of the occasions. The level of concordance between the subjective and objective moisture ratings was low to moderate or trivial for all moisture measures (0.002
0.05). CONCLUSIONS:Compared to objective measures, the subjective assessments were more accurate for ground hardness than for soil moisture levels and raters were just as likely to underestimate or overestimate the condition under review. This has implications for future sports injury aetiology studies that include ground condition assessments and particularly the use of subjective measures to underpin the development of future injury prevention strategies.

- Description: Context: The nature of Australian rules football (Australian football) predisposes both unique and common injuries compared with those sustained in other football codes. The game involves a combination of tackling, kicking, high-speed running (more than other football codes), and jumping. Two decades of injury surveillance has identified common injuries at the professional level (Australian Football League [AFL]). Objective: To provide an overview of injuries in Australian rules football, including injury rates, patterns, and mechanisms across all levels of play. Study Design: A narrative review of AFL injuries, football injury epidemiology, and biomechanical and physiological attributes of relevant injuries. Results: The overall injury incidence in the 2015 season was 41.7 injuries per club per season, with a prevalence of 156.2 missed games per club per season. Lower limb injuries are most prevalent, with hamstring strains accounting for 19.1 missed games per club per season. Hamstring strains relate to the volume of high-speed running required in addition to at times having to collect the ball while running in a position of hip flexion and knee extension. Anterior cruciate ligament injuries are also prevalent and can result from contact and noncontact incidents. In the upper limb, shoulder sprains and dislocations account for 11.5 missed games per club per season and largely resulted from tackling and contact. Concussion is less common in AFL than other tackling sports but remains an important injury, which has notably become more prevalent in recent years, theorized to be due to a more conservative approach to management. Although there are less injury surveillance data for non-AFL players (women, community-level, children), many of these injuries appear to also be common across all levels of play. Clinical Relevance: An understanding of injury profiles and mechanisms in Australian football is crucial in identifying methods to reduce injury risk and prepare players for the demands of the game. © 2017,

- Description: INTRODUCTION: Whilst football has been found to have many positive effects from a health perspective, injuries are common, particularly at the elite or professional level of play. Injury surveillance is therefore required to inform the development and implementation of strategies to increase safety in professional football codes. EVIDENCE ACQUISITION: A systematic search of peer reviewed and available grey literature was conducted to identify publications presenting methodological details of ongoing injury surveillance systems in professional football codes. Data extracted included population under surveillance, player/team coverage, injury definition and other relevant information. EVIDENCE SYNTHESIS: Following literature search and review, seven injury surveillance systems were identified that record ongoing data within professional football codes. A range of methodologies was used across the surveillance systems with variations in the definitions of injury, who records the data, the data-recording tool and dissemination of the data. CONCLUSIONS: There are many benefits for football associations, clubs and players themselves in conducting comprehensive injury surveillance. A range of surveillance methods is employed across the different football codes including injury definitions. Some professional football codes have developed consensus statements, which provide guidance on key issues relating to injury surveillance. Dissemination of findings differed with some systems publishing via peer review journals, with others through annual disclosure to the media. Financial considerations and funding are a crucial factor for creating and maintaining an injury surveillance system. Findings from professional football injury surveillance have been used to implement rule changes and develop preventive programmes, all aimed at increasing player safety.
