title: Predisposing risk factors on susceptibility to exertional heat illness: clinical decision-making considerations.
abstract: OBJECTIVE
  To present strategies for identifying predisposing conditions, susceptibility, and incidence reduction for the most common exertional heat illnesses (EHI): heat cramps, heat exhaustion, and most importantly, heat stroke.
  
  
  METHODS
  A comprehensive literature review of MEDLINE and 1996 to 2006, including all retrospective, controlled studies of EHI risk using the following keywords: exertional heat illness risk, exertional heat stroke risk, and exercise-induced dehydration risk. Search limits included the following: English language, published in the last 10 years, clinical trial, meta-analysis, practice guideline, randomized controlled trial, review, and humans. A manual review was conducted of relevant position statements and book chapters including the reference lists.
  
  
  METHODS
  To evaluate the quality of the empirical studies to be included in this review, each study must have scored at least 17/22 or 77% of items included when reporting a randomized trial using the CONSORT checklist.
  
  
  RESULTS
  Many cases of EHI are preventable and can be successfully treated if the ATC identifies individuals at increased relative risk and implement appropriate prevention strategies. The ability to objectively identify individuals at increased relative risk of EHI and to provide appropriate monitoring is critical in EHI prevention and reduction of repeated incidents of EHI.
  
  
  CONCLUSIONS
  For any heat illness prevention program to be effective, greater attention and continued observation is needed for athletes at high risk for EHI. For many athletic teams or programs, because of the sheer numbers and associated catastrophic injury potential, health care professionals must implement a system by which high-risk individuals are monitored during activity with the highest level of vigilance for prevention of EHI.
