Engelsk titel

Validity of injury reporting among active Swedish skydivers

Sammanfattning av projektet

Fallskärmshoppning som sport är en växande fritidsaktivitet. Årligen görs >5 miljoner hopp av >600 000 sporthoppare av båda könen och alla åldrar i >100 länder. Sverige har en internationellt sett stor hoppvolym och placerar sig väl på tävlingar. Svensk risk- och skadebild har kartlagts av sökande med utgångspunkt i Svenska Fallskärmsförbundets (SFF) register. All hoppning i Sverige sker inom ramen för SFF, med rapporteringsskyldighet för samtliga incidenter inklusive personskador. Anledning finns att granska validitets- och reliabilitetsaspekter i SFF:s register.

Syftet med studien är dels att studera och validera hur väl incidens och skadegrad av de inträffade skadorna överrensstämmer med SFF:s register, dels att fånga tidigare okända data ang. bl a könsspecifik hoppvolym, utrustning, samt utbildningsmetodik. Detta kommer att ske med en enkätstudie riktad till alla fallskärmshoppare aktiva i Sverige 2006 och 2007 (årlig totalpopulation cirka 2 000 personer).

Resultaten kommer att ligga till grund för framtida studier, med möjlighet att beskriva tidigare okända risk- och skadefaktorer, och bidra till skadeprevention inom fallskärmshoppning.

Kommentar från projektledaren

20090202: Lägesrapport valideringsprojektet. Artikeln är submitterad till internationell tidskrift. Jag och Mats har redovisat delar av resultaten, men kanske framför allt metoden, på världskongressen i fallskärmssäkerhet, Annual Meeting of the
FAI Parachuting Commission, 2009, Technical & Safety Committee. Svenska Fallskärmsförbundets Riksinstruktör Petter Alfsson-Thoor håller på att fundera på hur det tänkta nya elektroniska skaderapporteringssystemet ska bli så bra som möjligt.

2011-12-23: Lägesrapport valideringsprojektet. Artikeln publicerades i Accident Analysis and Prevention 42 (2010) 778–783. Den har fått bra uppmärksamhet och genomslag i enlighet med projektets syfte.

4. Detaljerad projektbeskrivning

Bakgrundsbeskrivning

Skydiving, sport parachuting from aircraft, engages approximately 675 000 participants in 118 countries, making circa 5.8 million sport jumps per year. Throughout the world, there are no unified reporting systems for skydiving related injuries; only a few countries have a mandatory system directed to its skydiving community. A few attempts to measure and estimate modern skydiving injury rates have been made. A skydiving convention in the United States 2000-2001 had a total injury rate of 170 per 100 000 jumps, with an accompanying hospital admission rate of 18 per 100 000 jumps. Similar injury rates have been reported from other European countries. A problem with the studies from the 1980s is that the sport underwent drastic changes in both technology, technique and sporting events during the 1990s.

A recent study of non-fatal Swedish skydiving injuries 1999-2003 found 257 non-fatal injury events distributed among 539 885 jumps, resulting in an injury rate of 48 per 100 000 jumps. This study indicated a higher risk of injury for female than male athletes, and showed a shift towards higher experience level among the most seriously injured. However, these findings could not be correlated to activity as jump volumes were unavailable at the individual level. Of two student-training systems, one had an incidence less than half that of the other (correlated to activity). In another recently published study of Swedish skydiving, it was found that of fatal injuries 1964-2003, student skydivers also had a high risk of fatality at a certain level of training in the educational system with a higher incidence of non-fatal injuries.

All sport parachuting from aircraft in Sweden currently takes place within the Swedish Parachute Association (Svenska Fallskärmsförbundet, SFF). This organisation maintains a member registry with national demographic and jump data, and collects data on incidents through a compulsory reporting system. Approximately 50 injuries are reported to SFF on a yearly basis, of an approximate yearly jump volume of 100 000 jumps. SFF has a compulsory reporting system for all injuries and potentially harmful events. However, it is a hypothesis that Swedish skydivers for unknown reasons sparsely report minor injuries and potentially harmful events.

Syfte

To study and evaluate the validity of the SFF register of injuries with respect to incidence and severity of injuries, and to collect hitherto unknown data, including jump volumes at the individual level.

Metod: Databearbetning

A letter will be sent to a skydiving population with login information to an online questionnaire. A lottery of skydiving equipment or travel tickets will be used as participation incentive. Initial non-responders will be sent a second letter. All responders reporting an injury and granting contact permission will be included in a database and contacted by telephone. Data collected from the online questionnaire will be compared to data collected by SFF with the old reporting system, and all living persons having reported an injury with the old reporting system but not with the online questionnaire will also be contacted. Hospital records will be retrieved after obtaining permission from the injured person. Human, equipment and environmental factors will be assessed for risk. Injury severity will be categorized using the Abbreviated Injury Scale (AIS) with every separate injury assigned an AIS value 1-6. Every separate incident will be categorized by the Maximum AIS value (MAIS) sustained in it.

Resultat

Submitted to a journal. Will be presented here after publication.

Diskussion

The collection of data regarding equipment and person in combination with jump volumes at the individual level may open hitherto unexplored areas of sport parachuting safety for study, and the evaluation of the validity of the SFF register may provide this organisation and similar organisations an opportunity to improve ongoing collection on incident data.
