Does policy change to allow pharmacist provision of influenza vaccination increase population uptake? A systematic review

Objective. The aims of this study were to estimate the effect of pharmacists' vaccinating for influenza on overall vaccination rates and to assess whether any effect differs for at-risk subgroups compared with the general population.Methods. A systematic review was undertaken, adhering to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Databases were searched during July 2019 and included Medline (Ovid), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus and the Cochrane Library.Results. The largest difference reported in overall population vaccination rates associated with pharmacists undertaking influenza vaccinations was an increase of 10%; the smallest showed no discernible effect. The effect was graduated: pharmacists with the most autonomy demonstrated the largest rate increases. There was evidence of substitution by pharmacists, but the effect size was small.Conclusions. The effect of allowing pharmacists to administer influenza vaccinations appears positive, but small. Given that pharmacists are likely to provide vaccinations at a lower cost than doctors, there may be cost-savings to the health system and consumers. Future research may include evaluating pharmacist-provided vaccinations compared with (or in combination with) other strategies, such as advertising, to increase access and uptake across the range of providers, as well as ongoing research to address vaccine hesitancy
