Background: With the help of the professional societies, the German Medical Association has drawn up new competence-based (model) specialty training regulations. The evaluation of pediatric specialty training has not yet been the subject of studies in Germany.Methods: In a two-stage Delphi procedure, specialists in pediatric and adolescent medicine and doctors in training assessed the contents of the specialty training on a four-stage scale. For this purpose, a total of 555 items were generated from the logbook of the German Academy of Pediatrics and Adolescent Medicine as well as from learning target catalogues of German-speaking universities and corporations. These were sent with the email distributors of the German Society for Pediatrics and Adolescent Medicine and the Professional Association of Pediatricians in Germany. The rating on the Likert scale was graded from “extremely important” = 4 to “unimportant” = 1. An item with a mean value of ≥3.0 became a core content and items with a value of <3.0 were extracted and sent again in the second round for voting alongside additional items.Results: In the first round of the two-stage procedure, 7800 questionnaire emails were sent out. A total of 259 responses were collected, 135 of which were completely filled in. In the second round, 11,786 questionnaire emails were sent, 903 replies were received with 572 completed questionnaires and 446 items were identified as core content. The items with the highest priority were the management of frequent emergency situations, the recognition of child abuse and the practice of vaccination. A comparison of the specialists in hospitals (n = 344) and private practices (n = 526) showed a significantly different evaluation in 20 out of 31 topics.Conclusion: This study, the first of its kind in Germany, scientifically investigated which contents of specialty training in the subject of pediatric and adolescent medicine can be regarded as core contents. The results show room for a significant reduction in the total amount of training objectives.
