Patient-Reported Outcome Measures for Pelvic Organ Prolapse: A Systematic Review Using the COnsensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) Checklist.

Background: Patient-reported outcome measures (PROMs) are recommended to measure the impact of a health condition or intervention effectiveness as they aim to capture what is most meaningful to patients. Several PROMs are used to evaluate pelvic organ prolapse (POP)-related domains, yet the measurement properties of these instruments have not been fully explored with a rigorous analysis of the methodological quality and quality of evidence.

Objective: To conduct a systematic review reporting on the measurement properties of PROMs used for the assessment of POP-related domains in accordance with the COSMIN guidelines.

Search strategy: Five databases were searched from inception to December 2023.

Selection criteria: Studies were eligible if they involved (1) at least one group of female adults diagnosed with or presenting with symptoms of POP; (2) a self-reported outcome measure (PROMs, questionnaires) to evaluate POP-related domains; and (3) at least one measurement property.

Data collection and analysis: Methodological quality and measurement quality were assessed using the COSMIN risk of bias (ROB) checklist and the COSMIN criteria for good measurement properties.

Main results: A total of 13 PROMs were included. The BIPOP had the lowest ROB for Content Validity. The POP-SS was the only PROM with sufficient evidence of adequate construct validity and responsiveness to be used in both surgical and conservative management settings.

Conclusion: This original work identified a gap in evidence regarding the measurement qualities of identified PROMs used in the POP population.
