BackgroundHealth-related quality of life (HRQoL) is an important patient-reported outcome that warrants greater attention in individuals who sustained a non-catastrophic injury in a road traffic crash. Additional robust data on HRQoL outcomes after a non-catastrophic injury are needed to effectively identify potential targets for studies of tertiary prevention of poor recovery after a crash.ObjectiveWe assessed the association between non-catastrophic road traffic crash injuries and HRQoL and factors that independently affect long-term HRQoL.MethodsIn this inception cohort study, injured participants (≥17 years old) were identified from various sources including hospital emergency departments by a medical examination by a registered healthcare professional in New South Wales (Australia) and followed up after 12 months. HRQoL was measured by the European Quality of Life-5 Dimensions (EQ-5D-3L) and Medical Outcomes Survey Short Form 12 items (SF-12). A range of socio-demographic, pre-injury health, psychological, and injury-related factors were considered potential predictors of HRQoL in regression analyses.ResultsAmong 2019 individuals identified, 1201 (59.5%) were followed up after 12 months. HRQoL significantly improved between baseline and 12-month follow-up: EQ-5D-3L summary score (0.41-unit difference); SF-12 physical component summary score (PCS; 13.6-unit difference) and mental component summary score (MCS; 3.5-unit difference). Over 12 months, HRQoL score was lower for people claiming compensation than others (P<0.0001). Key predictors of better 12-month EQ-5D-3L summary score and visual analogue scale score for pain were age, not claiming compensation, reduced body mass index, less pain severity, less pain-related disability, and less general psychological distress. Significant predictors of SF-12 PCS score were injury to the neck (P=0.02) or head or face (P=0.01), being a driver or passenger at the time of the crash (P<0.0001), hospital admission (P<0.0001) and pain severity (P<0.0001). Baseline variables associated with 12-month SF-12 MCS scores were head or face injury (P=0.02), pre-injury health (P=0.04), pre-injury psychological conditions (P=0.04), trauma-related distress (P=0.0002) and general psychological distress (P<0.0001).ConclusionsA wide spectrum of biopsychosocial factors contribute to HRQoL after a road traffic crash injury. These epidemiological data are potentially important because they could identify potential targets for studies of tertiary prevention of persistently poor HRQoL after such an injury.Copyright © 2019 Elsevier Masson SAS.
