Abstract

AIMS: To determine whether changes in questionnaire scores on symptoms and condition-specific quality of life reflect clinically relevant improvements in women with stress urinary incontinence (SUI). METHODS: We retrospectively analyzed questionnaires collected during a randomized controlled trial in women with SUI, that received pelvic floor muscle training (PFMT) in two different formats. We included 218 women that answered validated self-assessment questionnaires at baseline and at a 4-month follow-up. We registered changes on two questionnaires, the International Consultation on Incontinence Modular Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) and the Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol). We compared these score changes to responses from the Patient Global Impression of Improvement (PGI-I) questionnaire. Differences were analyzed with the Spearman rho and one-way-ANOVA. The minimum important difference (MID) was the mean change in score for women that experienced a small improvement. RESULTS: The PGI-I correlated significantly to both the ICIQ-UI SF (r = 0.547, P < 0.0001) and ICIQ-LUTSqol (r = 0.520, P < 0.0001). Thus, larger reductions in symptoms or quality of life scores were associated with greater impressions of improvement. The changes in ICIQ-UI SF and ICIQ-LUTSqol scores were significant across all PGI-I groups from "no change" to "very much improved" (P < 0.05). The MIDs were 2.52 (SD 2.56) for ICIQ-UI SF and 3.71 (SD 4.95) for ICIQ-LUTSqol. CONCLUSIONS: The change in ICIQ-UI SF and ICIQ-LUTSqol scores after PFMT reflected clinically relevant improvements in women with SUI. The MIDs established for this population may facilitate future research, treatment evaluations, and comparisons between studies.

  • The reductions in ICIQ-UI SF and ICIQ-LUTSqol scores at two years are greater than the established minimum important differences for pelvic floor muscle training for stress urinary incontinence (2.52 and 3.71, respectively).

    “The minimum important differences (MIDs) established for ICIQ‐UI SF and ICIQ‐LUTSqol after PFMT for SUI are 2.52 and 3.71, respectively 27; the reductions in symptom and qol scores reported here (at two years) are greater.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
