Abstract
BACKGROUND: Prevention of illness is important for a team physician. However, there are few studies that reported clinical aspects of illness of athletes with impairment. OBJECTIVE: To describe the clinical characteristics of the 385 illnesses reported on the a novel Web-based electronic injury and illness capturing system (WEB-IISS) during the London 2012 Paralympic Games. DESIGN: Part of a large prospective cohort study. SETTING: London 2012 Paralympic Games. PARTICIPANTS: Team physicians of 78 delegations (3329 athletes over 14 days) used WEB-IISS. Each day, information was recorded, which included daily team size and illness details, system affected, final diagnosis, type and onset of symptoms, training and/or competition days lost, and suspected cause. MAIN OUTCOME MEASUREMENT: Incidence of illness (illness per 1000 athlete days). RESULTS: The incidence of illness in the cohort was 8.3 per 1000 (95% confidence interval, 7.5-9.1) athlete days, and the percentage of athletes with an illness in this study was 9.2%. Respiratory system illnesses were the most common (39.4%), followed by the digestive system (15.8%), skin and subcutaneous system (11.8%), genitourinary system (8.8%), and nervous system (7.3%). Urinary tract illness was more common in athletes with spinal cord injury (22%) compared with the athletes with other impairments (0%-5%). Skin and subcutaneous illness varied from 0%-18% between impairment categories and was highest for athletes with spinal cord injury. Infections accounted for 40.8% of all illness and 19.5% of illness that resulted in a time loss of ≥1 day. In 34% of illnesses, symptoms were present for ≥1 day before being reported to the team physician. CONCLUSION: The majority of illnesses affected the respiratory, gastrointestinal, skin and subcutaneous, and genitourinary systems, and were mostly infective in nature. The highest number of all illnesses, including skin and subcutaneous illnesses, and urinary tract illnesses, were of athletes with spinal cord injury. Although most illnesses were not time-loss illnesses, 19.5% of illnesses resulted in ≥1 day lost. Team physicians should be aware that, in many cases of infection reported, the symptoms were already present the day before. A delay in reporting of symptoms >24 hours could have important clinical implications for athletes' medical care.
