Quality assessment of patient‐reported outcome measures for patients with multiple ear complaints

Abstract

AbstractIntroductionThere is an increased demand for well‐validated PROMs in otology. This study will systematically assess the methodological quality of all published patient‐reported outcome measures (PROMS) for patients with multiple ear complaints and to identify the best suitable PROM for use by clinicians treating patients with multiple ear complaints.MethodsAn extensive systematic mapping review of all otology questionnaires was performed to identify questionnaires measuring multiple ear complaints. The ‘Consensus‐based standards for the selection of health measurement Instruments’ (COSMIN) checklists were used to evaluate the quality of the questionnaire by two researchers. The worst item score per aspect of the methodological assessment counted.ResultsTwelve multiple‐complaint questionnaires were included in the study for quality assessment. Ten questionnaires were disease‐specific (COMQ‐12, CES, ZCMEI‐21, MD‐POSI, PAN‐QOL, ETDQ‐7, MDOQ, GYSSCDQ, COMOT‐15 and DEU‐MDDS). Two questionnaires were ear domain‐specific (OQUA and COQOL). The majority of multiple complaint questionnaires lacked good design with concept elicitation and patient involvement.ConclusionFor the majority of questionnaires, the quality assessment was inadequate as only a few authors consulted with patients affected by the complaints in the development. Modifications of earlier versions of PROMS or combinations of multiple questionnaires lead to ongoing (cross‐cultural) validation of these questionnaires albeit mediocre design and validation. The two domain‐specific questionnaires are the COQOL and OQUA, both with adequate quality but different focus. COQOL to quantify the quality of life and OQUA to measure and evaluate the severity and impact of ear complaints.
