Clinical Practices in Collegiate Concussion Management.

Background: In recent years, sports leagues and sports medicine experts have developed guidelines for concussion management. The extent to which current clinical practice is consistent with guideline recommendations is unclear. At the collegiate level, there have been few examinations of concussion management practices and the extent to which meaningful differences across divisions of competition exist.

Improving occupational injury surveillance by using a severity threshold: development of a new occupational health indicator.

Background: Hospital discharge data are used for occupational injury surveillance, but observed hospitalisation trends are affected by trends in healthcare practices and workers' compensation coverage that may increasingly impair ascertainment of minor injuries relative to severe injuries. The objectives of this study were to (1) describe the development of a severe injury definition for surveillance purposes and (2) assess the impact of imposing a severity threshold on estimated occupational and non-occupational injury trends.

Methods: Three independent methods were used to estimate injury severity for the severe injury definition.

Is Knee Separation During a Drop Jump Associated With Lower Extremity Injury in Adolescent Female Soccer Players?

Background: Knee injuries are common in older adolescent and adult female soccer players, and abnormal valgus knee appearance characterized by low normalized knee separation (NKS) is a proposed injury risk factor. What constitutes normal NKS in younger adolescents and whether low NKS is an injury risk factor are unknown.

Purpose: To determine the normal range of NKS using a drop-jump test in female perimenarchal youth soccer players and whether low NKS contributes to lower extremity injuries or knee injuries.

Validation of ICDPIC software injury severity scores using a large regional trauma registry.

Background: Administrative or quality improvement registries may or may not contain the elements needed for investigations by trauma researchers. International Classification of Diseases Program for Injury Categorisation (ICDPIC), a statistical program available through Stata, is a powerful tool that can extract injury severity scores from ICD-9-CM codes. We conducted a validation study for use of the ICDPIC in trauma research.

A case-control study of boat-related injuries and fatalities in Washington State.

Objectives: To identify risk factors associated with boat-related injuries and deaths.

Methods: We performed a case-control study using the Washington Boat Accident Investigation Report Database for 2003-2010. Cases were fatally injured boat occupants, and controls were non-fatally injured boat occupants involved in a boating incident.
