Evaluation of References Supporting Hospital Pharmacy Policies.

There is a lack of research evaluating the role of references in hospital policies. The goal of this study was to describe the type of literature used as a reference in medication policies and evaluate the agreement of the policy with evidence-based guidelines. One hundred forty-seven pharmacy owned policies met inclusion criteria; 27.2% of the policies contained references, in which tertiary literature was the most frequently cited source (90%), followed by primary (47.5%), and lastly secondary (27.5%). When references were used, all policies agreed with current guidelines. For policies without references, 3.7% disagreed with published guidelines. Disagreement with guidelines may negatively impact patient care, therefore health systems should incorporate librarians into clinical policy development and review to ensure the best available evidence is incorporated into polices.
