Trends and outcomes in pediatric laparoscopic appendectomy: a NSQIP-P analysis of same-day discharge and readmission rates.

Abstract

Purpose: Practice patterns of same-day discharge for pediatric laparoscopic appendectomy for non-perforated appendicitis are not well-analyzed. Our aim is to evaluate current practice patterns and outcomes of same-day discharge for these patients.

Methods: NSQIP-P retrospective registry identified patients (2017-2021) who underwent laparoscopic appendectomy for non-perforated appendicitis. Annual same-day discharge (SDD) rate was determined. SDD patients were compared to those discharged postoperative days 1-2 (non-SDD). Sub-group analysis was performed on ICD-10 code K35.30. Regression was performed.

Results: Overall, 67,214 patients were identified. The SDD rate increased from 33.3% (2017) to 52.5% (2021) with decreased 30-day readmissions between SDD and non-SDD (1.3% vs 2.1%, p < 0.001). Sub-group analysis identified 7,330 patients with SDD rates from 50.7% (2019) to 60.4% (2021) with decreased 30-day readmissions (1.3% vs 2.1%, p < 0.001) for SDD versus non-SDD. No increase in adverse events for SDD occurred in either analysis. Regression identified esophageal/gastric/intestinal diseases increased odds of early readmission or reoperation (OR 1.85, p = 0.042).

Conclusion: Same-day discharge after pediatric laparoscopic appendectomy for non-perforated acute appendicitis continues to increase in frequency without a significant increase in adverse outcomes. SDD rates are 20-30% lower than previously published single-center studies, indicating there is a likely a larger percentage of patients that could discharge same-day.

Level of evidence (i-v): Level III.
