Urinary Complications After Omitting Bladder Catheterization During Atrial Fibrillation Ablation
Medicine and Health Sciences
Context: Indwelling Urinary Catheterization (IUC) is among the most common procedures performed in the inpatient setting. Because there are risks associated with IUC, efforts to reduce its use when unnecessary should be made. Objective: Assess patient urinary and overall health outcomes after atrial fibrillation (Afib) ablation with and without IUC. Design: Retrospective cohort study of patients undergoing Afib ablation for paroxysmal atrial fibrillation between March 1 2017 and August 20 2018 at St Vincent Indianapolis Hospital. Setting: St Vincent Indianapolis is a tertiary referral center. All procedures were performed in the inpatient setting. All patients included in this study were over 18 years of age. The only exclusion criteria was for patients on dialysis at the time of procedure. Methods: Operative characteristics and patient identifying information were queried using Current Procedural Terminology (CPT) codes in the specified time frame. Patient characteristics and postop outcomes were assessed by manual chart review. Differences between patients who received IUC and patients who did not were assessed using Chi-Squared test for categorical data and Unpaired Student’s t-test for continuous data. Results: For our composite primary outcome of any urinary complication in the 7 days after procedure, 14 of 297 (4.71%) patients who underwent IUC developed complications, versus 0 of 92 who were not catheterized (P = 0.034). 1 patient developed urine retention, 3 were recatheterized, 6 developed UTI, 7 developed hematuria, 2 developed urethral pain, and 1 developed urethral trauma. Conclusions: Our study found a reduced rate of urinary complications after undergoing Afib ablation without IUC. Overall rates of complications were lower than expected. There is an ongoing randomized control trial investigating this same question that will ensure ascertainment of patient outcomes and reduce bias in patient assignment to treatment groups.
