Out-of-hours care in the Netherlands is under pressure. Workload for GPs during out-of-hours care is high and there are concerns about maintaining the quality of care. Since 80% of the complaints shown in out-of-hours care is neither complex nor urgent not all patients necessarily have to be seen by a GP.~A previous study (ID: 80-82800-98-227) indicated that shifting care from GPs to NPs is possible in terms of safety and quality of care and resulted in cost savings due to less treatment. In that study 4 GPs and 1 NP provided care in the experimental condition and 5 GPs provided care in the control condition. Based on the results it is hypothesized that NPs are competent to diagnose and treat at least 75% of the complaints shown in out-of-hours primary care. Substituting more GPs by NPs in out-of-hours care will probably lead to more cost savings.~In the current study care delivered and direct healthcare costs are compared between different team compositions. In the experimental condition care is provided by a team of NPs and GPs. The intervention starts with a team of 4 professionals in both the experimental (3 GPs and 1 NP) and the control (4 GPs) condition; in consecutive stages an extra GP is substituted by an NP aiming at replacing 3 out of 4 GPs with by NPs.~Control: 4 GPs~Stage 1: experimental: 3 GPs & 1 NP~Stage 2: experimental: 2 GPs & 2 NPs~Stage 3: experimental: 1 GP & 3 NPs~Both feasibility and cost-efficiency will lead to recommendations on the optimal balance in a team between GPs and NPs.
The aim of this study is to explore the effects of substitution in out-of-hours primary care. In consecutive stages an extra General Practitioner (GP) is substituted by a Nurse Practitioner (NP) aiming at replacing 3 out of 4 GPs by NPs. Effects are measured in terms of feasibility and cost-efficiency.
