AbstractThe Assessment of Quality of Life (AQoL) is a generic health-related quality of life (HRQL) measure. It is the only HRQL instrument, currently available, that incorporates health preference values derived from an Australian population and has been extensively trialled in over 40 studies. However, prior to this study, it had not been used to measure HRQL in injury patients. The aim of this study was to evaluate the AQoL, as a measure of the impact of injury on HRQL, by examining its correlation with other commonly used measures of health outcome and its ability to discriminate between groups with injuries of varying type and severity. A total of 221 admitted injury patients, aged 18-74 years, were recruited into the study from four major Victorian metropolitan hospitals and followed up over 12 months. The AQoL and the SF-36 were administered to obtain retrospective measures of pre-injury HRQL and health status with post-injury measurements obtained at five intervals post-injury (to 12 months). A preliminary analysis of data from this study showed the AQoL was positively related to other common outcome measures and, overall, showed a strong correlation with the SF-36 Physical Component Summary and a moderate correlation with the Mental Component Summary. It also demonstrated good discrimination between groups on the basis of type of injury, body region injured and severity of injury. While further testing of the AQoL, in this context, is still necessary, this study suggests that the AQoL may be a useful measure of the impact of injury on HRQL.
