Insights
Implementing a new guideline for appendicitis evaluation in children significantly reduced computed tomography (CT) scan use by 41%. This change improved imaging efficiency without impacting diagnostic accuracy or negative appendectomy rates.
Area of Science:
- Pediatric emergency medicine
- Radiology
- Surgical outcomes
Background:
- Computed tomography (CT) scans are frequently used for diagnosing appendicitis in children.
- Overutilization of CT scans raises concerns regarding radiation exposure and healthcare costs.
Purpose of the Study:
- To evaluate the impact of a clinical practice guideline on CT scan utilization for pediatric appendicitis.
- To assess changes in diagnostic accuracy and negative appendectomy rates after guideline implementation.
Main Methods:
- A multidisciplinary team developed a clinical pathway for pediatric abdominal pain evaluation.
- CT scan utilization rates were compared before and after the guideline's implementation.
Main Results:
- CT scan use for appendectomy patients decreased by 41% post-guideline implementation.
- The negative appendectomy rate remained stable (5.7% pre- vs. 5.2% post-implementation).
- CT use in patients transferred from outside hospitals decreased by 76%.
Conclusions:
- A clinical pathway emphasizing early surgical consultation and ultrasound can significantly reduce CT scan reliance for pediatric appendicitis.
- This approach maintains diagnostic accuracy and avoids an increase in negative appendectomies.
Objectives:
The objective of this study was to compare usage of computed tomography (CT) scan for evaluation of appendicitis in a children's hospital emergency department before and after implementation of a clinical practice guideline focused on early surgical consultation before obtaining advanced imaging.
Methods:
A multidisciplinary team met to create a pathway to formalize the evaluation of pediatric patients with abdominal pain. Computed tomography scan utilization rates were studied before and after pathway implementation.
Results:
Among patients who had appendectomy in the year before implementation (n = 70), 90% had CT scans, 6.9% had ultrasound, and 5.7% had no imaging. The negative appendectomy rate before implementation was 5.7%. In patients undergoing appendectomy in the postimplementation cohort (n = 96), 48% underwent CT, 39.6% underwent ultrasound, and 15.6% had no imaging. The negative appendectomy rate was 5.2%. We demonstrated a 41% decrease in CT use for patients undergoing appendectomy at our institution without an increase in the negative appendectomy rate or missed appendectomy. The results were even more striking when comparing the rate of CT scan use in the subset of patients undergoing appendectomy without imaging from an outside hospital. In these patients, CT scan utilization decreased from 82% to 20%, a 76% reduction in CT use in our facility after protocol implementation.
Conclusions:
Implementation of a clinical evaluation pathway emphasizing examination, early surgeon involvement, and utilization of ultrasound as the initial imaging modality for evaluation of abdominal pain concerning for appendicitis resulted in a marked decrease in the reliance on CT scanning without loss of diagnostic accuracy.
