Background: Controversy exists regarding how operative timing affects patient safety and resource utilization for acute appendicitis. Over 3 years, our institution trialed efforts to optimize appendectomy workflow. Our aim is to describe the ramifications of expediting appendectomy and implementing standardized protocols relative to historic controls.
Methods: Patient records at a freestanding children's hospital were reviewed from synchronized 6-month periods from 2019 to 2021. During Year 1 (historic), no standardized workflows existed. In Year 2 (expedited), appendicitis management was protocoled using a clinical quality improvement bundle, which included performing appendectomies within two hours of diagnosis. In Year 3 (QI), operative timing was relaxed to the same calendar day while all prior QI initiatives continued. Descriptive statistics were performed, using hospital length of stay (LOS) as the primary outcome.
Results: 298 patients underwent appendectomy for acute appendicitis. The median expedited workflow LOS was 15.3 hours shorter (p = 0.003) than historic controls; however, this was sustained despite relaxation of surgical urgency in the QI workflow. No differences in perforation rates were observed. During the expedited workflow, OR overtime staffing expense increased by $90,000 with no significant change in hospital costs. In multivariate regression, perforation was the only variable associated with LOS.
Conclusion: Hospital LOS can be shortened by expediting appendectomy. However, in our institution this did not decrease hospital costs and was furthermore balanced by higher personnel expenses. A sustained decrease in LOS after relaxing operative urgency standards implies that concurrent QI initiatives represent a more effective and cost-efficient strategy to decrease hospital resource utilization.
Level of evidence: Level III.
