Objective: To evaluate the impact of an ambulatory clinical pharmacy service (inclusive of immunization needs assessments) on the frequency and appropriateness of pneumococcal vaccine administration in a family medicine clinic.

Methods: This cohort study had an observational and retrospective design and included patients who received pneumococcal vaccines at a family medicine clinic in a medically underserved area in Southwestern Pennsylvania across a 42-month period from January 1, 2015, to June 30, 2018. The outcome measures included the administration and appropriateness of pneumococcal 13-valent conjugate (PCV13) and pneumococcal 23-valent polysaccharide (PPSV23) vaccines across 3 time cohorts including before, during, and after the establishment of a clinical pharmacy service.
