Are three-day voiding diaries feasible and reliable? Results from the Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) cohort.

ABSTRACT: AIMS:The aims of this study were to assess the completeness of voiding diaries in a research context and to correlate diary data with patient-reported questionnaires. METHODS:Men and women enrolled in the Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) were given a 3-day voiding and fluid-intake diary to fill-out. Diaries were assessed for completeness and intake-output imbalances. They were assigned to one of four categories based on a percentage of missing data and fluid imbalance: no diary submitted, unusable (>40% missing void or intake volumes, or unphysiological fluid imbalance), usable but not complete, and complete. RESULTS:A total of 1064 participants were enrolled and 85% (n?=?902) returned the bladder diary. Of the diaries returned, 94% (n?=?845) had data on three separate days, 87% (n?=?786) had no missing intake volumes, 61% (n?=?547) had no missing voided volumes, and 70% (n?=?635) had a fluid imbalance within 3?L across the 3-day time period, resulting in 50% (n?=?448) of participants with 100% complete diaries. Younger age was associated with a higher likelihood of not submitting a diary, or submitting an unusable diary. Women had a higher likelihood of submitting an unusable diary or a usable but incomplete diary. CONCLUSION:Overall, 50% of LURN participants returned voiding diaries with perfectly complete data. Incomplete data for voided volumes was the most common deficiency. There was only a moderate correlation between diary data and questionnaire responses, indicating that diaries are a source of unique information.
