Research from a recent American Academy of Pediatrics, Agency for Health Research & Quality (AHRQ) Improvement Innovation Network, showed that diagnoses for pediatric elevated blood pressure and adolescent depression improved and sustained with interventions developed during the project. It showed that missed or delayed actions for laboratory tests with abnormal results improved during the maintenance phase and after the intervention. The results were used to develop AHRQ’s Reducing Diagnostic Errors in Primary Care Pediatrics Toolkit.
