This study examined influences on scarring after burn in a prospective study using a defined outcome measure: scar height measured by a modified Vancouver Scar Scale (mVSS). A prospective case–control study was conducted among 616 adult subjects who sustained a burn in Western Australia. Patient factors influencing scar outcome including gender, Fitzpatrick skin type and selected co-morbidities were explored, as well as injury and clinical factors. A logistic regression model for raised scar after burn was developed which achieved an overall correct prediction rate of 81.1%; 74.8% for those with raised scar and 86.0% for those without raised scar. From this study, injury and clinical predictors for raised scar after adjustment for other variables are: increasing %TBSA, greater burn depth as indicated by level of surgical intervention, wound complications and prolonged hospital stay. Intrinsic patient predictors for raised scar in patients with comparable injuries are: young age (≤30 years), female gender and Fitzpatrick skin types 4–6. The strength of association statistics (odds ratios and 95% confidence intervals) reported will be of practical benefit for clinical decision-making and counselling of patients, and plausible biological explanations for the findings support the validity of the results.
