Abstract

INTRODUCTION AND HYPOTHESIS:

In order to assess the outcome following surgery for urinary incontinence (UI) and pelvic organ prolapse (POP) the importance of patient-reported outcome measures, in addition to the clinical objective measures, has been recognised. The International Consultation on Incontinence has initiated the development and evaluation of disease-specific questionnaires (ICIQ) to compare the patient's degree of improvement. Alternatively, the Patient's Global Impression of Improvement (PGI-I score) with an inherent before-after assessment has been widely accepted in recent studies. The aim of this study was to compare the PGI-I versus the ICIQ score for women undergoing UI or POP surgery.

METHODS:

This study is based on self-administered pre- and postoperative questionnaires, completed by women undergoing surgery for UI or POP in Denmark in 2013. Weighted Kappa statistics and 95 % limits of agreement method were used when comparing the PGI-I and ICIQ scores.

RESULTS:

Among the 3,310 women included the PGI-I score showed a higher improvement than the IQIC score, for UI 0.83 (CI 95 %: 0.80-0.85) vs 0.62 (0.60-0.64) and for POP 0.77 (0.75-0.78) vs 0.66 (0.65-0.67).

CONCLUSIONS:

The PGI-I score renders higher satisfaction than the ICIQ score and the PGI-I score overestimates the improvement following UI and POP surgery.
