The quality of life after motorcycle traffic injuries: a cohort study in northwest of Iran
Abstract Background: Quality of life (QOL) after motorcycle accident is an important and dynamic concept but the conducted research about QOL's injured motorcyclists is much less. Therefore, in this study we investigated the QOL of injured motorcyclists up to three months after their accident and determining the associated factors.Methods: In present study, 190 injured motorcyclists who admitted at the two referral specialized hospitals (Emam Reza and Shohada) in Tabriz, between June 2018 and January 2019, and agreed to participate were included in the study. All injured motorcyclists were contacted through the telephone one and 171 of them (90%) three months after their accident to complete an EQ-5D-3L questionnaire. The baseline measurement (such as demographic variables, time and place of accident, vehicles and individuals), were gathered by using face to face interview in the hospitals. The QOL score in this study could vary between 1-3. The higher score showed the lower QOL. The Generalized Estimating Equation (GEE) models were used to determine the factors affecting these motorcyclists’ QOL .Results: The injured motorcyclist’s QOL was relatively better three months after the accident (mean ± Standard Deviation: 2.15 ± 0.65) in comparison with their status a month after the accident (mean ± SD: 1.78 ± 0.51) (p<0.001). The multivariable model showed that individuals whose pelvis (Coef: 0.29, (95% Confidence Intervals [CI]: 0.16, 0.42), P= 0.001) and knee (Coef: 0.26, (95% CI: 0.10, 0.42), P= 0.001) were injured, experienced a lower QOL. Also, those whose accident had happened in rainy weather experienced lower QOL (Coef: 0.33, (95% CI: 0.12, 0.53), P= 0.001). Those who were in an accident with a vehicle experienced a better QOL than others (Coef: -0.26, (95% CI: -0.43, -0.09), P=0.002).Conclusion: The results showed the QOL of the injured people was improving from the first follow-up to the second one. It is recommended that by designing multi-year cohort studies, the QOL of motorcyclists be assessed for a longer time in order to identify the effective factors that improve the QOL of injured motorcyclists.
