Identification of delayed diagnosis of paediatric appendicitis in administrative data: a multicentre retrospective validation study.

ABSTRACT:

Objective

To derive and validate a tool that retrospectively identifies delayed diagnosis of appendicitis in administrative data with high accuracy.

Design

Cross-sectional study.

Setting

Five paediatric emergency departments (EDs).

Participants

669 patients under 21 years old with possible delayed diagnosis of appendicitis, defined as two ED encounters within 7 days, the second with appendicitis.

Outcome

Delayed diagnosis was defined as appendicitis being present but not diagnosed at the first ED encounter based on standardised record review.
