Objective: The purpose of this study was to develop and test a unique, new pelvic floor surgery complication scale and compare it with an existing validated measure. Study Design: Surgeons from 2 clinical trials networks rated complications based on perceived patient bother, severity, and duration of disability to develop a Pelvic Floor Complication Scale (PFCS). PFCS scores were calculated for subjects in 2 multicenter pelvic floor surgical trials. The PFCS and modified Clavien-Dindo scores were evaluated for associations with length of hospitalization, satisfaction, and quality-of-life measures (Health Utilities Index, Short Form-36, Urogenital Distress Inventory, and Incontinence Impact Questionnaire). Results: We calculated PFCS scores for 977 subjects. Higher PFCS and Clavien-Dindo scores similarly were associated with longer length of hospitalization (P <.01), lower satisfaction (P <.01), lower Health Utilities Index scores (P =.02), lower Short Form-36 scores (P =.02), higher Urogenital Distress Inventory scores (P <.01), and Incontinence Impact Questionnaire scores (P <.01) at 3 months. No associations were present at 1 year. Conclusion: The PFCS compares favorably to the validated modified Clavien-Dindo instrument. © 2013 Mosby, Inc.
