However, they are underutilized because of the need to carry paper, pen & a measuring device, the time needed to transpose the data, calculate the results & store the diary & summary in the patient's medical record. A bladder diary application solves most of these problems. Herein, we report the content & construct validity of an electronic bladder diary (EBD) app for a PDA (IOS, Android). METHODS Construct validity was achieved by an expert panel using questions from previously validated LUTS questionnaires & diaries. A diary algorithm was constructed for app development. Pre Alpha, white box & black box Alpha testing was done respectively by the developers & expert panel, computer literate & computer naïve patients & healthy volunteers. Content validity was achieved by having users complete the diary in privacy; afterwards, they were interviewed one on one by members of the research team & the app was revised accordingly. RESULTS The PDA app includes a prompt asking for the urge perception score (UPS) for each void, an incontinence question, a nocturia question & 2 voiding questions. The diary app accrues the 24-hour voided volume (VV), day time VV, night time VV, number of voids (day & night), maximum VV, number of incontinent episodes, number of urgency episodes, & a Rho value calculating the correlation between VV & the UPS. The diary and summary (figure 1) can be downloaded as a PDF or XML file. First-time users demonstrated an average time of use for each void of 65 seconds (Range: 45-120 seconds) and time decreased for each successive trial, indicating a very fast learning curve. CONCLUSIONS Users praised the ease of use of the beta version of the EBD. This application could replace traditional bladder diaries in the near future & could ultimately provide a means for patients to become managers of their own symptoms. Traditional bladder diaries present the doctor with a snapshot of a patient's symptoms; sequential use of this EBD could allow the patient to easily provide a reliable portrait of his symptoms over time. © 2013 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 189Issue 4SApril 2013Page: e804-e805 Advertisement Copyright & Permissions© 2013 by American Urological Association Education and Research, Inc.MetricsAuthor Information Jerry G.
