RT Journal Article SR Electronic T1 Communicating the risk of injury in schoolboy rugby: using Poisson probability as an alternative presentation of the epidemiology JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP 611 OP 613 DO 10.1136/bjsports-2011-090431 VO 46 IS 8 A1 Nikesh Parekh A1 Stewart D Hodges A1 Allyson M Pollock A1 Graham Kirkwood YR 2012 UL http://bjsm.bmj.com/content/46/8/611.abstract AB Background The communication of injury risk in rugby and other sports is underdeveloped and parents, children and coaches need to be better informed about risk. Method A Poisson distribution was used to transform population based incidence of injury into average probabilities of injury to individual players. Results The incidence of injury in schoolboy rugby matches range from 7 to 129.8 injuries per 1000 player-hours; these rates translate to average probabilities of injury to a player of between 12% and 90% over a season. Conclusion Incidence of injury and average probabilities of injury over a season should be published together in all future epidemiological studies on school rugby and other sports. More research is required on informing and communicating injury risks to parents, staff and children and how it affects monitoring, decision making and prevention strategies.
