Based on the experiences in our study, the implementation model of Grol and Wensing offers a useful approach to guideline implementation., It helps to plan and execute implementation activities systematically, and helps to develop implementation interventions that match the requirements of the target group. In our study, the factors that improved guideline adherence were interventions aimed at reorganizing the process of care, greater dissemination of knowledge about the guidelines (including the distribution of training materials to aid in following the guideline recommendations), and measures aimed at increasing normative social pressure in favour of adherence to the anxiety disorder guidelines. The method of implementation described in this study appears to be effective, and can be easily copied by others.
