RESUMO
OBJECTIVE: The objective of this study was to evaluate the effect of the Pediatric Emergency Care Applied Research Network (PECARN) blunt head trauma guidelines and implementation of urgent neurology follow-up (UNF) appointments on an observed decline in head computed tomography (CT) use for pediatric emergency department (PED) patients presenting with headache, seizure, and trauma. METHODS: Patients ages 0 to 18 years presenting to and discharged from an urban tertiary care PED with chief complaint of trauma, headache, and seizure between 2007 and 2013 were retrospectively included. The total number of head CTs obtained in the trauma, headache, and seizure groups was compared before and after the publication of the PECARN guidelines in 2009 and the implementation of urgent UNF within a week from PED discharge in 2011, respectively. RESULTS: Between 2007 and 2013, 24,434 encounters were identified with 2762 head CTs performed. Analysis demonstrated a decline in pediatric head CTs for trauma (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.8-2.2) after the publication of the PECARN study on blunt head trauma, for headache (OR, 1.4; 95% CI, 1.1-1.8) and seizure (OR, 1.9; 95% CI, 1.4-2.6) with UNF. However, cross comparison (headache and seizure with PECARN and trauma with UNF) also demonstrated similar significant declines. CONCLUSIONS: The decline in head CTs observed at our institution demonstrated a strong linear relationship, yet cannot be solely attributed to the PECARN blunt head trauma study or the implementation of UNF.
