Experience Sampling Method in OAB Patients

Summary

Rationale: The overactive bladder syndrome is diagnosed clinically by using the ICS criteria of ≥8 micturitions and at least 1 urgency episode per 24 hours. To determine whether patients fit the criteria, micturition diaries ('sensation-related bladder diaries') and other symptom questionnaires with considerable limitations are used. This makes it difficult to get a good impression of the fluctuation of complaints during the day / week. These limitations are overcome using the Experience Sampling Method (ESM). This is an electronic questioning method which is characterized by repeated and random, momentary assessments in the subject's current environment and state. This study follows other successful ESM studies done within the Gastroenterology and Psychiatry Department. The aim of this study is to evaluate if the ESM is more accurate in the assessment of urological complaints in OAB compared to the current assessment with the use of the sensations-related bladder diaries (SR-BDs) and retrospective questionnaires. Furthermore the aim is to assess the reliability and validity of this OAB-specific electronic patient-reported outcome measure (ePRO), based on the Experience Sampling Method-principle, for symptom assessment and assessment of triggers for symptoms in OAB.

Objective: To evaluate the accuracy of the ESM to assess urological complaints in OAB compared to SR-BDs and retrospective questionnaires. To assess content validity, reliability and the accuracy to validate the developed ePRO in OAB patients.

Study design: The ESM study is a multicentre, prospective, cross-sectional study.

Study population: 66 OAB patients will be recruited at the outpatient Pelvic Care Centre in Maastricht UMC+, Zuyderland Hospital and University Hospital Antwerp, 66 healthy volunteers will be recruited as well.

Methods: In a period of 7 days, participants will fill out an electronic ESM assessment at 10 random moments during the day. Moreover, they will fill out a sensation-related bladder diary (SR-BD) during the last three consecutive days of filling out the ESM and several symptom questionnaires at the end of the study period.

Main study endpoints: The main study outcome comprehends the psychometric properties of the PROM for symptom assessment of OAB symptoms. Secondary outcomes are increase in ESM score for OAB symptoms and environmental and psychosocial factors (e.g. as measured by the PROM) from one time point (t-1) to the next (t).
