Abstract

Simple Summary Radical prostatectomy (RP) is a common treatment for prostate cancer but has a risk of side-effects. Urinary incontinence (UI) after RP ranges from 4 to 31%, depending on the method of reporting and definitions used. The aim of this study was to evaluate if healthcare insurance claims data of absorbing pads in the Netherlands provide a valid alternative in the measurement of post-prostatectomy UI (defined as the use of >= 1 pad(s) per day), compared to self-reported pad use. Claims data and self-reported use was available for 416 patients. According to the claims data, patients had a UI rate of 31%, compared to a self-reported UI rate of 45% one year after RP. The agreement between both measures was moderate. Claims data can be considered as a conservative quality indicator for UI after RP.Abstract The use of healthcare insurance claims data for urinary incontinence (UI) pads has the potential to serve as an objective measure for assessing post-radical prostatectomy UI rates, but its validity for this purpose has not been established. The aim of this study is to correlate claims data with Patient Reported Outcome Measures (PROMs) for UI pad use. Patients who underwent RP in the Netherlands between September 2019 and February 2020 were included. Incontinence was defined as the daily use of >= 1 pad(s). Claims data for UI pads at 12-15 months after RP were extracted from a nationwide healthcare insurance database in the Netherlands. Participating hospitals provided PROMS data. In total, 1624 patients underwent RP. Corresponding data of 845 patients was provided by nine participating hospitals, of which 416 patients were matched with complete PROMs data. Claims data and PROMs showed 31% and 45% post-RP UI (>= 1 pads). UI according to claims data compared with PROMs had a sensitivity of 62%, specificity of 96%, PPV of 92%, NPV of 75% and accuracy of 81%. The agreement between both methods was moderate (kappa = 0.60). Claims data for pads moderately align with PROMs in assessing post-prostatectomy urinary incontinence and could be considered as a conservative quality indicator.
