Descriptive epidemiology of race-day jockey falls and injuries in New Zealand

The objective of the study was to determine the incidence of race-day jockey falls and describe the reporting of injuries occurring during Thoroughbred racing in New Zealand. Details on jockey falls and injuries were extracted from official stipendiary stewards' reports and denominator data on all race starts were obtained for all races that occurred between 1 August 2008 and 28 February 2013. A fall included any event of the jockey being dislodged from the horse, once the jockey had mounted to start the race proceedings. Incidence rates for jockey falls stratified by type of race were calculated for race-level variables of interest: year, season, race number, race distance and track condition. During the study period there were 816 jockey falls, of which 92 occurred before the race and resulted in the horse being scratched (withdrawn) from the race. The incidence of jockey falls was 2.2 per 1000 rides (95% confidence interval (CI)=1.9-2.5) for flat races and 84.7 per 1000 rides (95% CI=76.6-93.5) for jump races. Just under half of the jockey falls in flat races occurred pre-race (195/418; 46.6%), 42% (179/418) of falls occurred during the race and 10.5% (44/418) of falls occurred post-race. In total, 19.1% (80/418) and 17.3% (69/398) of jockey falls resulted in injury to the jockey in flat and jump races, respectively. Nearly 90% (69/80) of jockeys injured in flat races were stood down from their next race and most injured jockeys required a medical certificate before racing again. The incidence of jockey falls was higher in jump races than flat races, but was comparable to those reported internationally. Incidence rates for falls in flat races were lower than those reported in Europe and Australia.
