Sports-related injuries in New Zealand: National Insurance (Accident Compensation Corporation) claims for five sporting codes from 2012 to 2016

Objectives To provide epidemiological data and related costs for sport-related injuries of five sporting codes (cricket, netball, rugby league, rugby union and football) in New Zealand for moderate-to-serious and serious injury claims. Methods A retrospective analytical review using detailed descriptive epidemiological data obtained from the Accident Compensation Corporation (ACC) for 2012-2016. Results Over the 5 years of study data, rugby union recorded the most moderate-to-serious injury entitlement claims (25 226) and costs (New Zealand dollars (NZD$) 267 359 440 (139 pound 084 749)) resulting in the highest mean cost (NZD$ 10 484 ( pound 5454)) per moderateto-serious injury entitlement claim. Rugby union recorded more serious injury entitlement claims (n=454) than cricket (t((4))=-66.6; P<0.0001); netball (t((4))=-45.1; P<0.0001); rugby league (t((4))=-61.4; P<0.0001) and football (t((4))=66.6; P<0.0001) for 2012-2016. There was a twofold increase in the number of female moderate-to-serious injury entitlement claims for football (RR 2.6 (95% CI 2.2 to 2.9); P<0.0001) compared with cricket, and a threefold increase when compared with rugby union (risk ratio (RR) 3.1 (95% CI 2.9 to 3.3); P<0.0001). Moderate-to-serious concussion claims increased between 2012 and 2016 for netball (RR 3.7 (95% CI 1.9 to 7.1); P<0.0001), rugby union (RR 2.0 (95% CI 1.6 to 2.4); P<0.0001) and football (RR 2.3 (95% CI 1.6 to 3.2); P<0.0001). Nearly a quarter of moderate-to-serious entitlement claims (23%) and costs (24%) were to participants aged 35 years or older. Conclusions Rugby union and rugby league have the highest total number and costs associated with injury. Accurate sport exposure data are needed to enable injury risk calculations.
