Abstract Background Managing children with minor head trauma remains challenging for physicians who evaluate for the need for computed tomography (CT) imaging for clinically important traumatic brain injury (ciTBI) identification. The Pediatric Emergency Care Applied Research Network (PECARN) prediction rules were adopted in our pediatric emergency department (PED) in December 2013 to identify children at low risk for ciTBI. This study aimed to evaluate this implementation’s impact on CT rates and clinical outcomes. Methods Retrospective cohort study on pediatric patients with head trauma presenting to the PED of the American University of Beirut Medical Center in Lebanon. Participants were divided into pre- (December 2012 to December 2013) and post-PECARN (January 2014 to December 2016) groups. Patients were further divided into < 2 and ≥ 2 years and stratified into groups of low, intermediate and high risk for ciTBI. Bivariate analysis was conducted to determine differences between both groups. Results We included 1362 children of which 425 (31.2%) presented pre- and 937 (68.8%) presented post-PECARN rules implementation with 1090 (80.0%) of low, 214 (15.7%) of intermediate and 58 (4.3%) of high risk for ciTBI. CTs were ordered on 92 (21.6%) pre- versus 174 (18.6%) patients post-PECARN (p = 0.18). Among patients < 2 years, CT rates significantly decreased from 25.2% (34/135) to 16.5% (51/309) post-PECARN (p = 0.03), and dropped in all risk groups but only significantly for low risk patients from 20.7% (24/116) to 11.4% (30/264) (p = 0.02). There was no significant decrease in CT rates in patients ≥2 years (20% pre (58/290) vs 19.6% post (123/628), p = 0.88). There was no increase in bounce back numbers, nor in admission rates or positive CT findings among bounce backs. Conclusions PECARN rules implementation did not significantly change the overall CT scan rate but reduced the CT scan rate in patients aged < 2 years at low risk of ciTBI. The implementation did not increase the number of missed ciTBI.
