Demonstration of the validity of the SF-36 for measurement of the temporal recovery of quality of life outcomes in burns survivors.
OBJECTIVE
Outcome assessment after burn is complex. Determination of quality of life is often measured using the Burns Specific Health Scale (BSHS), a validated tool in the burn population. The SF-36 is a generic quality of life questionnaire that is validated for numerous populations, but not in burns. The aim of the study was to examine the validity of SF-36, using the BSHS as a reference.


METHODS
280 burn patients were recruited at Royal Perth Hospital. Each completed SF-36 and BSHS-B at regular intervals to 2 years after burn. Regression modelling was used to assess the temporal validity and the relative sensitivity of the measures.


RESULTS
SF-36 domains and BSHS-B demonstrated significant associations at all time points (r=0.37-0.76, p<0.002). In the months after burn, SF-36 domains: role physical; bodily pain; social function and role emotional outperformed BSHS-B total score and domain scores. Greater measurement sensitivity was demonstrated in all SF-36 summary and subscales measures (except General Health) when compared to BSHS-B and sub-domains.


CONCLUSIONS
This study demonstrated SF-36 as a valid measure of recovery of quality of life in the burn patient population. The data suggests that SF-36 components were more sensitive to change than the BSHS-B from ∼1 month after injury.
