Current status of patient-reported outcome measures and other subjective assessment grading tools in bladder pain syndrome.

introduction and hypothesisBladder pain syndrome (BPS) is characterised by chronic pain in the bladder area accompanied by urgency and/or frequency without the presence of other confusable diseases. Owing to a lack of gold standard diagnostic tests and definitive cure it is paramount to define treatment goals and validated measurements of outcomes. Patient-reported outcome measures (PROMs) are validated questionnaires completed by patients that can help to reduce ambiguity in the BPS patient treatment pathway, but they are currently underutilised. We present to our knowledge the first summary and analysis of all available PROMs in BPS patients.

methodsReview and critical evaluation of all relevant BPS guidelines presented in English language and a systematic search for PubMed database articles relating to PROMs and subjective assessment grading tools in BPS, interstitial cystitis and chronic pelvic pain syndrome.

resultsThe ideal PROMs for BPS should assess urinary symptoms, pain, quality of life and sexual health. There are five PROMs designed specifically for BPS patients. The most universally used and quoted is the O'Leary-Sant questionnaire followed by the Pelvic Pain and Urgency Score and the Wisconsin Interstitial Cystitis scale. However, there is no single PROM for BPS that is ideal, and for comprehensive assessment several questionnaires are often used simultaneously.

conclusionsPatient-reported outcome measures are a valuable tool for use in the long-term management of patients burdened with BPS. There are now several disease-specific PROMs in use that have their respective advantages and disadvantages. Their use should be encouraged in future research as well as continued efforts to develop new PROMs that can address current shortcomings.
