Figure 11 Hospital-treated towed water sports injury by age group, Victoria July 1, 2006 to June 30, 2007 (n=388) Percentage of admissions and presentations 25 20 15 10 5 0 Admissions (n=91) Presentations (n=297) 5–9 10–14 15–19 20–24 25–29 30–34 35–39 40–44 45–49 50–54 55–59 Age group Sources: Victorian Admitted Episodes Dataset (VAED) and Victorian Emergency Minimum Dataset (VEMD) 5.5.1.1 Hospital admissions (n =91) In 2006/7, towed water sports accounted for 41% of all admissions for recreational boating-related injuries. There were 91 admissions for towed water sports in 2006/7 (86 of which were related to water skiing and wakeboarding) resuming the upward trend evident from 1999/2000 to 2004/5 (Figure 10). Males were over represented (77%). The age groups with higher injury frequency were 20-24 year olds (23%), followed by 15-19 years olds (19%) and 30-34 year olds (15%). Injuries were mostly to the lower extremity (34%) and head and face (22%). Injuries to the upper extremity (25%) and the trunk (12%) accounted for most of the remaining cases. Thirty-five percent of towed water sport admissions were fractures and 21% were dislocations, sprains and strains. The most common specific injuries were knee and lower leg fractures (11%), shoulder and upper arm dislocation/sprain/strain (9%), knee and lower leg dislocation/sprain/strain (7%). Sixty-eight percent of towed water sport injury cases stayed in hospital less than 2 days, 24% stayed 2-7 days and 8% stayed 8-30 days. The major causes of injury were: falls (44%), hit/struck/crush (11%), and over exertion (9%). The VAED does not provide any detail of the circumstances of the injury. However, analysis of case narrative data for admissions recorded on the VEMD (n = 29) provided some more information on the circumstances of injury. Injury scenarios included the following: 52
• Waterskiing: arm caught in rope, rope burn to arm, degloving injury to foot from ski rope, whiplash to neck, hit a tree, hit a branch, water in eye and lost corneal transplant, boat ran over legs, fell, ‘accident at 160k/h’. • Wakeboarding: fell from wakeboard, fell fracturing hip, struck by boat propeller, twisted foot • Kneeboarding: fell off kneeboard, skied into boat, collided with stationary houseboat • Towed inflatable: fell off sea biscuit, fell on tube and struck nose on sibling’s knee 5.5.1.2 Hospital ED presentations (non-admissions) (n = 297) Forty-one percent of the recreational boating-related injury ED presentations in 2006/7 were associated with water skiing and related towed water sports, the same proportion as in 2005/6. There were 6 more towed water sport injury presentations in 2006/7, compared with the previous year (Figure 10). Sixty-three percent (n=188) of ED presentations for towed water sports injuries were related to water skiing; a further 18% (n=54) to wakeboarding, 7% to kneeboarding and 12% (n=36) to biscuit and inflatable tube riding. Overall, 76% of ED presentations were male. Males were over-represented in ED presentations for all towed water sports activities but not to the same degree: waterskiing (80% male), wakeboarding (78%); kneeboarding (65%); and inflatable riding (54%). Overall, the 5-year age group with the highest frequency of injury was persons aged 20-24 years (23%), followed by persons aged 15-19 (21%) (Figure 12). This pattern was evident in three of the four water sports. Injured kneeboarders tended to be older, with 25-29 year olds ranking second on frequency of ED presentations.
