The design and evaluation of a quick checklist for urodynamic quality control: A prospective single-center small sample study.

ABSTRACT

PURPOSE: To design a quick checklist for urodynamic study (UDS), aiming to reduce the occurrence of errors in the process, which may help to increase the quality of UDS. And further to analyze the effectiveness of this quick checklist for UDS quality control. METHODS: First, a quick checklist for uroflow study and pressure-flow study was developed, based on the International Continence Society-Good Urodynamic Practice standards, our previous studies, and recent literature, as well as expert suggestions. Then, patients who underwent UDS between January 2023 to February 2023 were randomly assigned to a study group or a control group. For the study group, the quick checklist was used throughout the UDS process, while the control group did not. The main artefacts were chosen to verify the effectiveness of the quick checklist for improving the UDS quality. RESULTS: The quick checklist comprised three subtypes checklist for patients, checklist for environment and device, and checklist for UDS test process. 38 UDS traces per group were included. The incidence of missing the standard cough test decreased significantly from 18.4% to 0 (p = 0.012), with the checklist implementation. The baseline drift frequency rate also declined significantly from 39.5% to 5.3% (p < 0.05). Volume < 150 mL on uroflow study occurred in 68.4% of cases and its frequency rate decreased significantly with checklist implementation (p < 0.05). CONCLUSION: A quick checklist for quality control of UDS was developed. The quick checklist as a convenient, quick, and easy used urodynamic quality control method, may help to reduce the technical artefacts and improve fundamental urodynamic quality control. Future research with a larger sample size is needed to confirm the effectiveness of the checklist.
