Inspectorates have been criticized for assessing compliance with the rules rather than outcomes for children. In the Netherlands, inspectorates have developed a ‘journey tool’ to reconstruct children's travels through all the organizations providing care. Using document analysis and semi‐structured interviews, we evaluated how inspectors use this tool in practice. We applied an ontological theoretical framework to the coordination of care to analyse 24 journeys through care organizations, including a selection of six journeys in further detail. Our analysis shows that up until now, inspectors used only one form of coordination, the creation of a hierarchy, resulting in one problem definition. However, in complex care practices, children have multiple and often incompatible problems so that one coherent problem definition cannot be made. We show that ‘patchwork’, a form of coordination that allows discrepancies enables inspectors to reflect on complex care practices and evaluate options to improve outcomes for children.
