There is a lack of convincing evidence favoring one type of intervention or a specific combination of interventions when implementing guidelines, however. Based on studies into changing medical care within the somatic health care system, Grol and Grimshaw also conclude that no ready-made implementation strategy is superior in all situations. They therefore suggest an implementation model that is to be tailor-made matching the specific setting and the needs of the target group among which changed behavior is sought. In our study we use such an implementation model described by Grol and Wensing which, because of its global and transparent structure, offers the possibility to tailor-make the implementation strategy. This implementation model of Grol and Wensing consists of several steps that help to plan, execute and evaluate implementation systematically.
