of data is coded using the fourth AM edition that includes detailed activity codes for sport and recreational activities including a list of codes for boating sports and adventure sports. Deaths recorded on VAED were excluded to avoid over counting of fatalities. 1.2.2.3 Emergency department presentation data In 2006/7 the Victorian Emergency Minimum Dataset (VEMD) captured presentations to 38 hospital Emergency Departments (ED) representing all Victorian public hospitals with a 24-hour ED service. ED presentations for injury to private hospitals and public hospitals with limited provision of ED services (mostly small metropolitan and rural hospitals) are not captured on the VEMD. There are no codes to identify boating-related injury ED presentations on the VEMD, so case narratives (descriptions) were searched to identify specific boating-related injury cases. Keywords used in the search included: biscuit, boat, canoe, catamaran, dinghy, jet ski, kayak, kitesurf, kneeboard, parasail, PWC, sail, raft, rowing, runabout, tinny, tube, wakeboard, waterski, windsurf and yacht (and spelling variations of these terms). Injury cases related to aquatic activities that are out of scope for MSV were excluded such as injuries that occurred during body and board surfing, surf ski riding, scuba diving, snorkelling, and swimming (except swim to shore from a boat). Injury cases that occurred in boat sheds or when a person was working/ repairing a boat or boat building (model and otherwise) and non-specific skiing injury cases that occurred during the official snow skiing season (June to September) were also excluded. Deaths in the ED and cases that were subsequently admitted to hospital were excluded to avoid over counting of cases. However, the case narrative data for hospital admissions recorded on the VEMD were analysed to provide additional information on the circumstances of the injury, as the VAED contains no case descriptions (narratives). Boating-related ED presentations are underestimated in this report because the quality of case narrative data varies across participating hospitals. 1.3 Exposure data In studying risk it is critical to know the level of relevant activity (or exposure to risk). For example, two deaths for every 1,000 hours of exposure to recreational boating reflect a better safety system than two deaths for every 500 hours of exposure. Unfortunately, there is almost no available ‘time at risk’ information on which to estimate the relative risk of injury in the different types of marine activities, for example personal watercraft riding versus water skiing. Some jurisdictions report marine incidents per registered vessel as a substitute for exposure (usage) data, following the precedent set in the road safety field. For recreational vessels however, usage is only indirectly related to ownership. Other jurisdictions report incidents per participant. Because of the unavailability of Victorian boating participation and exposure data, population data were used to form the denominator in this study. Although frequency data (as reported here) are useful for priority setting, they are sub-optimal for planning and evaluation of prevention programs. 14
2. Structure of the report and definitions 2.1 Structure Cases extracted from the four datasets are classified and reported according to the class of vessel involved in the incident: commercial, hire drive and recreational. Each incident is allocated to only one category. If two classes of vessel are involved in the one incident then the incident is classified according to the ‘higher’ category of vessel involved, with commercial vessels ranked above hire drive, then recreational vessels. Within these three broad categories both non-injury (‘serious’ and ‘response only’ incidents) and injury (fatal and non-fatal) incidents are reported. 2.2 Definitions Commercial vessel A commercial vessel is any vessel, other than one under the control of the Department of Defence, which is operated in connection with a commercial transaction of any kind including operation as a business, service, for profit or research. It is important to note that responsibility for large commercial vessels (and vessel safety) rest primarily with the Commonwealth. The jurisdiction of MSV for commercial vessel safety matters is confined to Victorian registered vessels such as commercial fishing vessels, small ferries and other passenger vessels and the like. Hire Drive vessel A hire drive vessel is any boat or vessel that is let for hire or reward or for any other consideration including vessels provided in conjunction with holiday establishments or hotels for the use of guests or tenants and which the hirer uses solely for pleasure. Recreational vessel Recreational vessels are those used solely for the purpose of recreational or sporting activities and not used for hire or reward. Response only incidents ‘Response only’ incidents are incidents covered by the MIR system but not covered by the definition of a ‘marine incident’ in the national reference manual. They include: • disablement of vessel i.e. when a vessel has broken down or been disabled • persons in trouble i.e. no vessel was involved but activity still happened in the water e.g., person on body board has been swept out to sea False alarms (incident is a false alarm but still be responded to) and non-marine incidents (no vessel was involved and activity did not happen in the water e.g. rock fisherman trapped on rocks) were not included in counts in 2007/8 and were removed from the 2005/6 and 2006/7 counts for trend analysis and when data for 2007/8 were being compared to data for 2006/7. Serious incidents Serious incidents conform to the definition of a ‘marine incident’ in the national reference manual and include incidents resulting in hospital admission; and vessel-related incidents involving collision; grounding; capsizing; sinking; swamping; flooding; loss or presumed loss of vessel; loss of stability; fire; explosion; person overboard; onboard incident; other person injury; and close quarters.
