A Review of the Scoring and Assessment of Keratosis Pilaris

Madeline A Wang et al. Skin Appendage Disord. 2023 Aug.

Abstract

Disease severity assessment tools play a large part in evaluating skin conditions in dermatology. Currently, there is no existing validated assessment tool for keratosis pilaris (KP), a benign yet highly prevalent follicular disorder. A range of proposed scoring tools have been used in different clinical trials for the assessment of potential treatments for KP. A literature review of the current scoring systems used for KP shows that there is a lack of consistency with most studies using varying versions of unvalidated investigator global assessment (IGA) scores and quartile grading systems. A review of these studies shows that current methods of evaluating KP in clinical trials are subjective, unreliable, and inconsistent. A standardised and validated scoring system would be significant as it could be used in clinical trials to advance the current knowledge of KP.
