Overview

•First known systematic review reporting the impact of pharmacist immunizers on vaccination rates.•Limited number of randomized controlled trials and high quality studies.•Pharmacist involvement in immunization services increased vaccine coverage rates. Underutilization of vaccination programs remains a significant public health concern. Pharmacists serve as educators, facilitators, and in some jurisdictions, as administrators of vaccines. Though pharmacists have been involved with immunizations in various ways for many years, there has yet to be a systematic review assessing the impact of pharmacists as immunizers in these three roles. To complete a systematic review of the literature on the impact of pharmacists as educators, facilitators, and administrators of vaccines on immunization rates. We identified 2825 articles searching the following databases from inception until October 2015: PubMed, EMBASE, Cochrane Libraries, Cumulative Index to Nursing and Allied Health Literature, International Pharmaceutical Abstracts, Google Scholar. Grey literature was identified through use of the Canadian Agency for Drugs and Technology in Health “Grey Matters” search tool. Content from relevant journals and references of included studies were also searched. Inclusion criteria were clinical or epidemiologic studies in which pharmacists were involved in the immunization process. Studies were excluded if no comparator was reported. Two reviewers independently completed data extraction and bias assessments using standardized forms. Thirty-six studies were included in the review, 22 assessed the role of pharmacists as educators and/or facilitators and 14 assessed their role as administrators of vaccines. All studies reviewed found an increase in vaccine coverage when pharmacists were involved in the immunization process, regardless of role (educator, facilitator, administrator) or vaccine administered (e.g., influenza, pneumococcal), when compared to vaccine provision by traditional providers without pharmacist involvement. Limitations of the results include the large number of non-randomized trials and the heterogeneity between study designs. Pharmacist involvement in immunization, whether as educators, facilitators, or administrators of vaccines, resulted in increased uptake of immunizations. PROSPERO Registration: CRD42013005067.
