Abstract
OBJECTIVE: To assess the effectiveness of a portable electronic diary as a data collection device for overactive bladder symptoms, and to evaluate its level of patient acceptability compared with a conventional paper‐based voiding diary.PATIENTS AND METHODS: Patients were identified through USA and UK hospital incontinence clinics. Patients were trained in the use of paper and electronic diaries before randomization, to complete either diary for 7 days. The diaries were then collected and, after a further training session, patients completed the other diary type for 7 days.RESULTS: In all, 35 patients were recruited into the trial; overall, patients using the paper diaries (35) and electronic diaries (33) recorded similar data for the median number of incontinent episodes per week (8.2 and 7.0, respectively) and for the median number of significant leaks per day (0.4 and 0.5, respectively). However, the number of daily micturitions was slightly lower for the electronic than for the paper diary (7.3 vs 8.5, respectively). The frequency of urgency recorded in the electronic diary was higher than that recorded in the paper diary (5.8 vs 4.7). As 94% of patients found the electronic diary easy to use, and the electronic diary reflects real‐time data entries, the electronic diary data may provide a more accurate reflection of patient symptoms.CONCLUSION: We confirmed that the electronic diary is a novel method of collecting clinically relevant symptom data from patients with an overactive bladder. In addition, the ease‐of‐use ratings support the use of the electronic diary as a superior alternative to paper diaries, providing real‐time data which can be rapidly analysed, and thus allowing a speedy review of data during ongoing clinical studies.
