Background: Diagnostic testing is prevalent among children with persistent non-specific symptoms (PNS), and both undertesting and overtesting have negative consequences for child and society. Research in adults with PNS has shown that GPs use diagnostic testing for reasons other than diagnosis, but comparable research has not, to the best of our knowledge, been conducted in children. Understanding GPs' perspectives of testing decisions in children could provide insights into mechanisms of undertesting and overtesting.

Background: For diagnostic research on appendicitis in registration data, insight is needed in the way GPs generate medical records. We aimed to reach a consensus on the features that GPs consider important in the consultation and medical records when evaluating a child with suspected appendicitis.
Methods: We performed a three-round Delphi study among Dutch GPs selected by purposive sampling.
Background: Recognising acute appendicitis in children presenting with acute abdominal pain in primary care is challenging. General practitioners (GPs) may benefit from a clinical prediction rule.
Objectives: To develop and validate a clinical prediction rule for acute appendicitis in children presenting with acute abdominal pain in primary care.
