Expedited Surgical Care of Appendicitis is Associated With Improved Resource Utilization.

INTRODUCTION: Appendectomy for acute appendicitis is the most common pediatric intra-abdominal operation. Current literature supports the notion that modest in-hospital, preoperative delays are not associated with greater patient morbidity. However, there is less certainty regarding the role that hour-of-presentation plays in determining the timing of surgery. Thus, we aimed to evaluate how after-hours presentation may relate to the timing of surgery and to assess the outcomes and resource utilization associated with expedited appendectomy compared to nonexpedited. METHODS: Patient records for children who underwent an appendectomy at a freestanding pediatric hospital from 2015 to 2019 were reviewed. Business hour presentations were defined as arrival at the emergency department from 7 AM to 6 PM. Primary outcomes were hospital length of stay (LOS), cost derived from the Pediatric Health Information System database, perforation, surgical complications, and 30-day readmissions. RESULTS: Nine hundred forty-two patients underwent appendectomy over the study period. The median time to OR was 2.0 h in the expedited cohort and 9.8 h in the nonexpedited group. Presentation during business hours was associated with 4.4 higher odds (P < 0.001) of expedited workflow. Expedited appendectomies were associated with shorter hospital LOS (11.5 h, P < 0.001), less costly admissions ($1,155, P < 0.001); LOS measured in midnights, perforation and readmission rates were similar between groups. CONCLUSIONS: We found reduced resource utilization associated with expedited appendectomy. Additionally, the demonstrated association between the time of presentation to the emergency department (ED) and the timing of surgery may be utilized to inform staffing and resource deployment decisions. Further research regarding the generalizability and sustainability of an expedited presurgical workflow in pediatric appendectomy is certainly indicated.

The costs and benefits of emergent surgical workflow for acute appendicitis in children.

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.

Timeliness of pediatric surgical appendicitis care is associated with time of hospital admission.

BACKGROUND: Despite the frequency of acute appendicitis in children, there is no evidence-based consensus surrounding the urgency of the operation if a diagnosis is made after regular business hours. Although a modest delay in time to operation does not increase disease severity, postponing cases to the next calendar day may be associated with higher resource utilization. We aimed to evaluate the trend of delaying appendectomies to the next calendar day and its associated outcomes. METHODS: We queried the Pediatric Health Information System to analyze appendectomy patients younger than 18 y of age from 2010 to 2018. Same-day appendectomy and next-day appendectomy cohorts were created using admission hour and operative day. Healthcare cost, length of stay, surgical complications, and 30-day readmission rates were collected. Bivariate analyses and multivariable regressions were used to evaluate groups stratified by time of presentation. RESULTS: During the study period, 113,662 appendectomies were performed, comprising 88,715 (78.1%) same-day appendectomies and 24,947 (21.9%) next-day appendectomies. A higher proportion of same-day appendectomies (80.5%) were performed during hours 12:00am to 5:00pm and 19.5% were performed during hours 6:00pm to 11:00pm. The trend of next-day appendectomies increased during the study period from 13.9% to 20.2%. This was primarily evident in the 6:00pm to 11:00pm period. The 5:00pm cutoff was most predictive of a next-day appendectomy. Next-day appendectomies had similar rates of surgical complications; however, they were associated with higher costs, longer lengths of stay, and higher readmission rates. CONCLUSION: As the understanding of appendicitis urgency has changed, a more tempered approach of delivering surgical care has trended. Although short delays appear safe, postponement to the next calendar day is associated with higher resource utilization.
