The primary outcome in this study is more appropriate and comprehensive referrals and a more seamless and smoother referral process with reduced workload for both partners. The referral rates may be reduced by higher awareness of non-prioritized medical conditions. The use of priority setting and waiting time according to the national prioritization guidelines can give a higher correlation between GPs and hospital consultants about priority setting and waiting time. In this study we will evaluate the effect of a multifaceted educational intervention (a training program in priority setting) on the appropriateness and comprehensiveness of referrals in terms of the agreement on priority setting and waiting time between GPs and hospital consultants.
