Objectives: To evaluate changes in imaging practices for pediatric head trauma after publication of the Pediatric Emergency Care Applied Research Network (PECARN) guidelines, explore areas for quality improvement regarding neuroradiology referrals. We also sought to determine the prevalence of incidental findings discovered on computed tomographies (CTs) attained for minor head trauma and ascertain disposition in these cases.
Methods: This retrospective study was conducted at a rural academic center and included 156 children who received CTs for head trauma between 2005 and 2015. Subjects were divided into 2 groups: pre-PECARN publication and post-PECARN publication. Electronic medical records were reviewed to determine whether or not head CTs were obtained according to PECARN guidelines. The proportion of scanned cases and incidental findings in each group was then compared.
Results: Significantly more subjects met PECARN criteria for head CT during the pre-PECARN period (67.1% vs 50.6%, P = 0.04). Among those who met PECARN criteria, severe mechanism of injury was the most common criterion met in both groups (43.8% pre-PECARN and 26.5% post-PECARN). Nine (5.7%) subjects had incidental findings (similar for both study periods), of which 3 prompted additional diagnostic testing or invasive intervention. Among those who did not meet PECARN criteria, the most common mechanism of injury was fall (<3 ft).
Conclusions: Implementation of PECARN guidelines at our center remained limited in the 5 years after publication of this practice guide. Clinically insignificant incidental findings were often detected and may heighten patient anxiety.
