Variability in the management of infants under 3 months with minor head injury in paediatric emergency departments

Abstract

IntroductionIn the assessment of infants younger than 3 months with minor traumatic head injury (MHI), it is essential to adapt the indication of imaging tests. The Pediatric Head Injury/Trauma Algorithm (PECARN) clinical prediction rule is the most widely used to guide clinical decision making. ObjectivesTo analyse the variability in the performance of imaging tests in infants under 3 months with MHI in paediatric emergency departments (PEDs) and the adherence of each hospital to the recommendations of the PECARN rule. Population and methodsWe conducted a prospective multicentre observational study in 13 paediatric emergency departments in Spain between May 2017 and November 2020. ResultsOf 21 981 children with MHI, 366 (1.7%) were aged less than 3 months; 195 (53.3%) underwent neuroimaging, with performance of CT scans in 37 (10.1%; interhospital range, 0%–40.0%), skull X-rays in 162 (44.3 %; range, 0%–100%) and transfontanellar ultrasound scans in 22 (6.0%; range, 0%–24.0%). The established recommendations were followed in 25.6% (10/39) of infants classified as high-risk based on PECARN criteria (range, 0%–100%); 37.1% (36/97) classified as intermediate-risk (range, 0%–100%) and 57.4% (132/230) classified as low-risk (range, 0%–100%). ConclusionWe found substantial variability and low adherence to the PECARN recommendations in the performance of imaging tests in infants aged less than 3 months with MHI in Spanish PEDs, mainly due to an excessive use of skull X-rays.
