SUFU 2021: Subgrouping of Patients With Urologic Chronic Pelvic Pain Based on Pain and Urinary Symptoms: A Mapp Network Analysis
This was reliability and validation data for subgrouping patients on these two dimensions. 578 UCPPS research participants (193M, 385F) were classified into mild, moderate, or severe tertiles of USS and PPS at baseline (week 4) and these subgroup designations were examined for stability (reliability) using Interclass Correlations Coefficients (ICCs) over four weekly assessments prior to the baseline visit. The tertile classifications were then examined for convergent and divergent validity by comparing subgroups across multiple UCPPS clinical measures using a general linear model (GLM) approach. Sex was included as a potential moderator of these relationships. Both USS and PPS classifications were stable over the four assessments (ICC=0.78 and 0.67, respectively). USS compared to PPS was more strongly associated with urge during a laboratory bladder filling procedure and heightened sensory sensitivity. PSS compared to USS was more strongly related to pelvic floor tenderness on exam, the spread of genital/pelvic pain, and mental health quality of life (QOL). Both dimensions were independently associated with physical health QOL, widespread non-urological symptoms, and neuropathic-like sensations.
This analysis further supports the validity and utility of a two-dimensional, pelvic pain and urinary symptoms assessment framework for UCPPS. The use of a mild, moderate or severe classification for each dimension provides a validated method for subgrouping patients in clinical practice and clinical trials.
