Burns Scar Index (Vancouver Scar Scale)
Introduction[edit | edit source]
Developed in 1990 by Sullivan et al, the Vancouver Scar Scale (VSS) was the first widely used assessment to record burns scars using a semi-quantitative approach, in order to measure change in scar appearance during healing and treatment. It is one of the most frequently used outcome measures for scar assessment.
The impacts of scarring can be multifaceted, including movement and function limitations, long term pain or psycho-social effects, and therefore use of an outcome measure is beneficial to monitor the scars' progress.

Method of Use[edit | edit source]
Four characteristics of the scar are assessed. These are: vascularity, height, pliability, and pigmentation. Each characteristic is given a score, which are added together to give an overall score between 0 and 13.
Evidence[edit | edit source]
Reliability[edit | edit source]
There is not strong evidence for the reliability of the VSS, with one systematic review describing the reliability as indeterminate. Especially when the scar is larger in size or an asymmetrical shape. Nonetheless, a more recent journal found "moderate" inter-rater reliability and "acceptable" internal consistency.
Research suggests different modifications to improve the reliability, including to improve the clarity of the instructions and increase teaching of how to apply the VSS, or the use of a pocket tool.
Validity[edit | edit source]
The VSS is described as one of the first validated scar assessment tools. However, more recent systematic reviews do not support this claim. But, because the VSS is often modified, in multiple different ways including changing the existing items or adding extra ones, it is difficult to accurately assess the validity on a large scale. Moreover, within the research the majority of subjects were adult Caucasian males, limiting the validity to this population.
Responsiveness[edit | edit source]
Among all burn scar scales, there is only preliminary evidence supporting their accuracy in measuring changes to the scar over time.
The VSS does not measure patients own subjective assessment of the scar, such as pain or itching, or the impact on their day to day life. It is anticipated also incorporating these factors into an outcome measure would improve patient centered care and satisfaction.
