Measurement properties of quality-of-life outcome measures for children and adults with eczema: An updated systematic review

Objective: The aim of this updated systematic review was to systematically assess the measurement properties of previously discussed and new quality-of-life patient-reported outcome measures (PROMs) in children and adults with eczema using the new COSMIN guideline.

Methods: A systematic literature search was conducted in PubMed and EMBASE. Eligible studies reported on measurement properties of quality-of-life PROMs for children and adults with eczema. The methodological quality of selected already known PROMs and new evidence identified through the literature search was assessed with the COSMIN Risk of Bias checklist. The adequacy of included PROMs was judged with updated quality criteria, and the quality of evidence of the summarized results was graded. Finally, PROMs were placed in a recommendation category (A-C).

Results: In total, 133 measurement properties of nine different PROMs were assessed. No PROM could be placed in category A due to a lack of validation studies. Only the DLQI fulfilled the criteria for category C and therefore should not be recommended for use. All other PROMs were placed in category B, that is, they still have the opportunity to be recommended, but need further validation.

Conclusions: Currently, no PROM for quality of life can be recommended for use in children and adults with eczema. Further validation is needed. The DLQI cannot be recommended for future use.
