Deriving literature-based benchmarks for pediatric appendectomy and cholecystectomy complications from national databases in high-income countries: A systematic review and meta-analysis.

Background: Health systems must identify preventable adverse outcomes to improve surgical safety. We conducted a systematic review to determine national rates of postoperative complications associated with two common pediatric surgery operations in High-Income Countries (HICs).

Methods: National database studies of complication rates associated with pediatric appendectomies and cholecystectomies (2000-2016) in Canada, the US, and the UK were included.
