Implementing a guideline for the treatment of type 2 diabetics: results of a cluster-randomized controlled trial (C-RCT).

Background: In Italy many diabetics still lack adequate care in general practice. We assessed the effectiveness of different strategies for the implementation of an evidence-based guideline for the management of non-complicated type 2 diabetes among General Practitioners (GPs) of Lazio region.

Methods: Three-arm cluster-randomised controlled trial with GPs as units of randomisation (clusters).
