[Successful implementation of pharmaceutical intervention at an acute medical admission unit].

We document the process of implementing a clinical pharmacist service at the acute medical admission unit at Odense University Hospital. During the period December 2009 through April 2010 we reviewed 915 medication lists, which resulted in 628 interventions with generic substitution as the most frequent. The overall acceptance rate was 80%, albeit varying from 99% for generic substitution to 25% for change of administration route.
