Abstract Objectives To evaluate the association of clinician demographics and practice patterns with delayed diagnosis of appendicitis. Methods We included children with appendicitis at 13 regional emergency departments (EDs). We screened patients with a previous ED visit within 7 days for delayed diagnosis by chart review. We evaluated the association of clinician characteristics using logistic regression with random intercepts for site and clinician and delay as the outcome. Results Among 7,452 children with appendicitis, 105 (1.4%) had delayed diagnosis. Clinicians in the lowest quartile of obtaining blood in their general practice were more likely to have delayed diagnosis (odds ratio 4.9 compared to highest quartile, 95% confidence interval 1.8, 13.8). Clinicians’ imaging rates, specialty, sex, and experience were not associated with delayed diagnosis. Conclusions Clinicians who used more blood tests in their general practice had a lower risk of delayed diagnosis of appendicitis, possible evidence that lower risk tolerance has benefits.
