Agreement between patient global impression scale of improvement, pelvic floor distress inventory and 15D in measuring the outcome of pelvic organ prolapse surgery.

The weak correlations between 15D, PGI-I, and PDFI-20 observed in this study show that the quantified health gains are strongly dependent on the chosen patient-reported outcome measures. This demonstrates the importance of using condition-specific sensitive outcome measures in assessing the impact of surgical treatment in pelvic organ prolapse.
