False‐negative and False‐positive Errors in Abdominal Pain Evaluation Failure to Diagnose Acute Appendicitis and Unnecessary Surgery

Abstract

Errors in physician diagnostic decisions correlated with patient clinical findings, i.e., the missed diagnoses were on appendicitis patients with few clinical findings and unnecessary surgeries were on non-appendicitis patients with clinical findings similar to those of patients with appendicitis. Adverse events (perforation, abscess formation) correlated with physician false-negative decisions.
