Current scales for assessing human scarring: a review

Abstract

Patients can have wide-ranging problems related to scars, in terms of cosmesis, function, symptoms, psychological problems and overall quality of life issues. A range of treatments have been recommended for problematic scarring, however it has been acknowledged that the evidence base for most of the recommendations for scar therapy is limited, with few studies using validated measures of scar assessment in generating data. This review critically evaluates the subjective scar assessment scales developed to date and provides an insight into developments required in this area for the future. The principles of psychometric theory are discussed as a means of developing reliable and valid outcome measures and these are also applicable for measuring outcomes in other fields of plastic surgery research.
