In this article, the new Dutch pediatric guideline Brief Resolved Unexplained Event is discussed, which replaces the old guideline Apparent Life Threatening Event. The main goal of the new guideline is identification of a group of low-risk infants who need not be admitted to the hospital and in which only limited diagnostic workup is indicated. Three fictional cases are presented to highlight the major changes in management of infants who present with an unexplained event. Application of the new guideline will likely result in less clinical admissions and diagnostic testing in these patients.
