Questioning Prophylactic Antibiotic Use for Pyloromyotomy: Analysis of the Pediatric Health Information System...

Area of Science:

• Pediatric Surgery
• Infectious Disease Prevention
• Evidence-Based Medicine

Background:

• Pyloromyotomy, a surgery for pyloric stenosis, has low wound complication rates.
• Antibiotic prophylaxis is commonly administered despite low complication rates.
• The necessity of antibiotic prophylaxis for pyloromyotomy requires further investigation.

Purpose of the Study:

• To determine if prophylactic antibiotics reduce wound complications after pyloromyotomy in infants.
• To analyze the impact of antibiotic prophylaxis on complication rates in pediatric patients undergoing pyloromyotomy.
• To assess variations in antibiotic prophylaxis usage across hospitals.

Main Methods:

• Utilized the Pediatric Health Information System (PHIS) database for infant pyloric stenosis cases (2016-2021).
• Analyzed patient demographics, comorbidities, and 30-day post-pyloromyotomy complications.
• Employed logistic regression to evaluate the effect of antibiotic prophylaxis on complication rates.

Main Results:

• 14,247 infants underwent pyloromyotomy; 29.5% received antibiotic prophylaxis.
• Patients receiving antibiotics had higher rates of NICU admission, chronic conditions, and prematurity (p < 0.01).
• Complication rates were similar: 1.64% with antibiotics vs. 1.62% without (OR 1.10; p = 0.93).

Conclusions:

• Significant variation in hospital antibiotic prophylaxis practices for pyloromyotomy was observed.
• No statistically significant difference in complication rates was found between infants who received antibiotics and those who did not.
• Findings suggest that prophylactic antibiotics are unnecessary for pyloromyotomy.
