Middle managers' role in implementing evidence-based practices in healthcare: a systematic review.

Our findings suggest that middle managers may play an important role in facilitating EBP implementation. Included studies offered little understanding regarding the relative importance of various roles, potential moderators of the relationship between middle managers' roles and EBP implementation, or determinants of middle managers' role in EBP implementation. Future studies should seek to understand determinants and moderators of middle managers' role. Clearer understanding may facilitate the translation of evidence into practice.
