Unveiling patterns in pediatric appendectomy: A comparative study on healthcare resource capacity and surgical decisions in Brazil

BACKGROUND: Appendicitis is the most prevalent surgical emergency in children. This study examined hospital infrastructure, surgical techniques, patient demographics, and hospitalization parameters to assess the provision of safe and adequate care within the Brazilian public healthcare system. METHODS: Pediatric hospitalizations for acute appendicitis in 2022 were extracted from the Brazilian national database. We included all hospitalizations for patients aged 0-16 years with a primary ICD-10 diagnosis of acute appendicitis who underwent an operation. Parameters of interest were the type of surgical approach, mortality, and total cost of hospitalization. Facilities were defined as basic-facility, full-facility, and pediatric according to the level of pediatric resources available. RESULTS: In 2022, there were 29,983 pediatric appendectomies due to acute appendicitis. Of these, 90.2% were open appendectomies. Most occurred in basic-facility general hospitals (53.0%), followed by full-facility (35.2%) and pediatric hospitals (11.8%). Full-facility hospitals had a higher median cost (USD126.3, IQR 99.5-154.4) compared to basic (USD96.8, IQR 87.6-130.1) and pediatric hospitals (USD103.0, IQR 91.9-117.5), though the cost difference between basic and pediatric was not significant (p = 0.367). Death was a rare event across all levels of hospital infrastructure and for all types of procedures performed. CONCLUSIONS: The majority of hospitalizations for acute appendicitis occurred in hospitals with minimal pediatric infrastructure. Open appendectomies remain the most predominant procedure across all hospital types.
