The Pediatric Emergency Care Applied Research Network (PECARN) rule was the most common intervention (71%); most studies (75%) used multifaceted interventions (median components: 3; IQR: 1.75 to 4). Before\u2013after studies assessing multi-faceted PECARN interventions reported decreased computed tomography (CT) head imaging (relative risk = 0.73; IQR: 0.60 to 0.89).
