Factors affecting the response rate of frequency volume chart: A prospective nonrandomized controlled study.

ABSTRACT

AIMS: To evaluate if compliance with frequency volume charts can be improved if a physician explains its importance and to identify factors affecting compliance and accurate responses to frequency volume chart (FVC). METHODS: We identified patients ≥18 years of age with voiding dysfunction reported from July 2013 to February 2014. Patients were explained the importance of frequency volume charts by a doctor and then a nurse explained how to fill it (group A). Others were only explained how to fill it (group B). RESULTS: A total of 137 patients were enrolled. The response rate to frequency volume charts was higher in group A than in group B (94.3% vs 82.9%, P = .038). Patients ≥70 years of age, without a private health insurance, with high school education or higher, and without past medical history had a higher response rate in group A than in group B. In the multivariate binary logistic regression analysis, group A (odds ratio [OR], 4.87; 95% confidence interval [95% CI], 1.04-22.89; P = .045) and QoL (OR, 2.28; 95% CI, 1.16-4.46; P = .017) were factors associated with the response rate. In addition, group A (OR, 3.46; 95% CI, 1.03-11.70; P = .045) and being 60's years old (vs 50's years, OR, 7.01; 95% CI, 1.36-36.23; P = .020) were related to FVC complete response rate. CONCLUSIONS: Frequency volume chart compliance can be improved if physicians explain its importance for lower urinary tract symptoms diagnosis and management. The explanation and severe lower urinary tract symptoms are factors affecting compliance and the explanation and being 60's years old are related to accurate response.
