PurposeThis study investigated the improvement of interprofessional practice in primary care by performing the first three steps of the implementation model described by Grol et al. This article describes the targets for improvement in a setting for children with complex care needs (step 1), the identification of barriers and facilitators influencing interprofessional practice (step 2), and the development of a tailored interprofessional process model (step 3).MethodsIn step 2, thirteen qualitative semistructured interviews were held with several stakeholders, including parents of children, an occupational therapist, a speech and language therapist, a physical therapist, the manager of the team, two general practitioners, a psychologist, and a primary school teacher. The data were analyzed using directed content analysis and using the domains of the Chronic Care Model as a framework. In step 3, a project group was formed to develop helpful strategies, including the development of an interprofessional process through process mapping.ResultsIn step 2, it was found that the most important barriers to implementing interprofessional practice related to the lack of structure in the care process. A process model for interprofessional primary care was developed for the target group.ConclusionThe lack of a shared view of what is involved in the process of interprofessional practice was the most important barrier to its successful implementation. It is suggested that the tailored process developed, supported with the appropriate tools, may provide both professional staff and their clients, in this setting but also in other areas of primary care, with insight to the care process and a clear representation of “who should do what, when, and how.”
