Methods/design Investigators will conduct a pragmatic cluster randomised trial comparing implementation of the six recommendations using tailored interventions with usual care. Investigators will randomize 80 municipalities into one of two groups: an intervention group, to which investigators will deliver tailored interventions to implement the six recommendations, and a control group, to which investigators will not deliver any intervention. Investigators will randomise municipalities rather than patients, individual clinicians or practices because we will deliver the intervention for the first three recommendations at the municipal level and investigators want to minimise the risk of contamination across practices for the other three recommendations. The primary outcome is the proportion of general practitioners' behaviours which are consistent with the recommendations.
