Abstract

Background and Objectives: Postoperative urinary retention (POUR) is associated with significant morbidity. Our institution's POUR rate was elevated among patients undergoing elective lumbar spinal surgery. We sought to demonstrate that our quality improvement (QI) intervention would significantly lower our POUR rate and length of stay (LOS).

 

Methods: A resident-led QI intervention was implemented from October 2017 to 2018 on 422 patients in an academically affiliated community teaching hospital. This consisted of standardized intraoperative indwelling catheter utilization, postoperative catheterization protocol, prophylactic tamsulosin, and early ambulation after surgery. Baseline data on 277 patients were collected retrospectively from October 2015 to September 2016. Primary outcomes were POUR and LOS. The focus, analyze, develop, execute, and evaluate (FADE) model was used. Multivariable analyses were used. P value <.05 was considered significant.

 

Results: We analyzed 699 patients (277 pre-intervention vs 422 post-intervention). The POUR rate (6.9% vs 2.6%, [DELTA] confidence interval [CI] 1.15-8.08, P = .007) and mean LOS (2.94 +/- 1.87 days vs 2.56 +/- 2.2 days, [DELTA] CI 0.066-0.68, P = .017) were significantly improved following our intervention. Logistic regression demonstrated that the intervention was independently associated with significantly decreased odds for developing POUR (odds ratio [OR] = 0.38, CI 0.17-0.83, P = .015). Diabetes (OR = 2.25, CI 1.03-4.92, P = .04) and longer surgery duration (OR = 1.006, CI 1.002-1.01, P = .002) were independently associated with increased odds of developing POUR.

 

Conclusions: After implementing our POUR QI project for patients undergoing elective lumbar spine surgery, the institutional POUR rate significantly decreased by 4.3% (62% reduction) and LOS, by 0.37 days. We demonstrated that a standardized POUR care bundle was independently associated with a significant decrease in the odds of developing POUR.
