Abstract
Introduction: Motorcycles are quickly increasing in popularity and more and more motorcycles are being registered in Australia. Western-Australia in particular sees the highest increase in motorcycle registrations. However, as more motorcycles are being ridden, the number of accidents also increases quickly, leading to more injury and death. Motorcyclists are the most vulnerable group of road users, with risks of serious injuries that are 9 to 10 times as high as for occupants of cars. Most research has focused on risk factors for crashing bikes and for increased risk of fatality. Fewer have focused on positive outcome of these accidents. This prospective study aims to identify factors that can predict recovery at 3 and 6 months after a motorbike accident. Methods: All patients who had suffered a motorbike accident and were admitted to Royal Perth Hospital and seen by the trauma team were eligible for inclusion. Data collection consisted of three parts. 1- an initial interview at the hospital after the accident, to include demographic and accident details, 2- follow-up interviews focusing on recovery, pain, return to work and emotional health, by phone at 3 months after the accident and again at 6 months if the patients had not yet recovered and 3- an audit of medical files to retrieve injury and treatment details. These details were first assessed univariately to assess their relationship to recovery and then added to a multivariable logistic regression to develop a prediction model for recovery at 3 and 6 months after the accident. Results: For the initial interview 463 patients participated, 275 (59%) answered the questionnaire at 3 months after the accident and of those who had not recovered at 3 months, 82 (60%) participated in the 6-month questionnaire. At 3 months, 139 patients (50.5%) had recovered. The variables that predicted recovery after the multivariable logistic regression at 3 months were single vehicle mechanism (OR 4.88, 95%CI 2.22-10.77), off-road accident location (OR 0.96, 95%CI 0.96-3.99), shorter length of stay (OR 2.49 and 3.2, 95%CI 0.78-9.91), presence of upper extremity injury (OR 2.36, 95%CI1.17-4.77) and rehabilitation after hospital stay (OR 3.18, 95%CI 1.13-8.98). Of the 6-month participants, 37% had recovered, so 63% of this group had not yet recovered 6 months after the accident. The variables that predicted recovery at 6 months were absence of upper extremity fracture (OR 2.97, 95%CI 068-13.05), absence of pelvic injury (OR 20.42, 95%CI 2.17-192.02), rehabilitation after hospital stay (OR 6.39, 95%CI 1.01), BMI (OR 1.14 and 7.75, 95%CI 0.14-50.26) and presence of comorbidities (OR 6.30, 95%CI 1.26-31.49). Discussion/conclusion: Multiple variables showed univariate relationships to recovery, several of which also predicted recovery in a multivariable logistic regression. No other studies have focused specifically on recovery as an outcome variable for motorbike accidents; therefore it was difficult to compare all results those in current literature. More research is required to assess if the results in this study can be repeated and to confirm its findings.
