BACKGROUND: Pruritus assessment is difficult due to the varying subjective nature of the experience. There have been several validated tools described to quantify the severity of itch, however these tools fail to provide a comprehensive assessment or are too cumbersome and therefore lack usability. Our novel burn assessment tool, "The Pruritus Severity Scale" (PSS) allows for accurate quantification of itch components. The aim of this study was to assess its use in the burns population. METHODS: A prospective observational study was conducted on all patients over five years of age with a burn injury over a six month period. Patients underwent subjective evaluation of their itch as determined by two validated scores, the Visual Analogue Scale (VAS) and the Itch Man scale (IMS) and in addition to the PSS. The pruritus severity scale was correlated with the previously validated scoring methods using bi-variate correlations. RESULTS: Twenty-two patients were included in the study. The most common cause of injury was due to flame burn. The mean total body surface area was 6.5% (range: 1-26%). Both the IMS and the VAS positively correlated well with the PSS. The Spearman Coefficient for the PSS vs IMS was 0.81, R2 = 0.65 (P<0.05). The Spearman Coefficient for the PSS vs VAS was 0.87 (R2 = 0.76 (P<0.01)). There is a positive linear relationship between our novel scoring methods and the currently validated methods, indicating its validity as a burn assessment too. CONCLUSION: The Pruritus Severity Scale was shown to be an accurate, objective tool that was able to effectively record the patient's experience of itch. We believe that this novel score is quick, easy to use and allows for more comprehensive assessment than other short assessment tools. IJBT
