Objectives: The TEN-4-FACESp bruising clinical decision rule (BCDR) is a validated screening tool utilizing information about a child's body region bruised, age, and pattern of bruising to predict abuse in children younger than 4 years of age. Our objectives were to (1) evaluate the accuracy of the BCDR in predicting abuse when only 1 bruise was present and (2) identify other characteristics differentiating abusive from accidental injury in young children with a single bruise.
Methods: Patients included in this secondary analysis were those from the BCDR validation study whose only skin finding was a single bruise (including petechiae, subconjunctival hemorrhage, or frenulum injury).
