Method: In addition to a thorough literature review, the authors have conducted interviews with two chief physician executives at two very different divisions.Results: Based on existing theory and the interviews there is a lack of using medical guidelines in the health sector. The literature review theory state that active implementation strategies are most efficient. Furthermore, theory reveals that the group developing the guidelines should consists of people with different specialties and that the group leader should involve every participant in the group.

The responsibility concerning implementing medical guidelines is held by the group developing the guidelines, the management team, and the clinicians themselves.
