A systematic review of reported outcomes and outcome measures in randomized trials evaluating surgical interventions for posterior vaginal prolapse to aid development of a core outcome set

BACKGROUND: Recent systematic reviews have demonstrated wide variations on outcome measure selection and outcome reporting in trials on surgical treatments for anterior, apical and mesh prolapse surgery. A systematic review of reported outcomes and outcome measures in posterior compartment vaginal prolapse interventions is highly warranted in the process of developing core outcome sets. OBJECTIVE: To evaluate outcome and outcome measures reporting in posterior prolapse surgical trials. SEARCH STRATEGY: We searched MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL). SELECTION CRITERIA: Randomized trials evaluating the efficacy and safety of different surgical interventions for posterior compartment vaginal prolapse. DATA COLLECTION AND ANALYSIS: Two researchers independently assessed studies for inclusion, evaluated methodological quality, and extracted relevant data. Methodological quality, outcome reporting quality and publication characteristics were evaluated. MAIN RESULTS: Twenty-seven interventional and four follow-up trials were included. Seventeen studies enrolled patients with posterior compartment surgery as the sole procedure and 14 with multicompartment procedures. Eighty-three reported outcomes and 45 outcome measures were identified. The most frequently reported outcomes were blood loss (20 studies, 74%), pain (18 studies, 66%) and infection (16 studies, 59%). CONCLUSIONS: Wide variations in reported outcomes and outcome measures were found. Until a core outcome set is established, we propose an interim core outcome set that could include the three most commonly reported outcomes of the following domains: hospitalization; intraoperative, postoperative urinary, gastrointestinal, vaginal and sexual outcomes; clinical effectiveness.
