Interventions to improve hand hygiene compliance in patient care: Reflections on three systematic reviews for the Cochrane Collaboration 2007-2017.

This article presents highlights from a recently updated systematic Cochrane review evaluating the effectiveness of interventions to improve hand hygiene compliance in patient care. It is an advance on the two earlier reviews we undertook on the same topic as it has, for the first time, provided very rigorous synthesis of evidence that such interventions can improve practice. In this article, we provide highlights from a recently updated Cochrane systematic review. We identify omissions in the information reported and point out important aspects of hand hygiene intervention studies that were beyond the scope of the review. A full report of the review is available free of charge on the Cochrane website.
