Vaccination Rates in Patients With Medical Indications for the Pneumococcal Polysaccharide Vaccine in a Family Medicine Clinic.

Background: Pneumococcal vaccination rates among high-risk patients (eg, diabetes, asthma, smoking) seen in 2 family medicine clinics are unknown.

Objectives: To assess differences in pneumococcal polysaccharide vaccination rates and reasons for nonvaccination among patients with diabetes and asthma and patients who smoke.

Methods: A chart review at 2 family medicine residency training clinics showed 425 patients with a medical indication for PPSV23 were seen between April 1, 2015, and April 30, 2015. One reviewer searched the electronic health records to assess reasons for nonvaccination.

Results: Rates of nonvaccination were 29.8% in patients with diabetes, 58.7% in patients with asthma, and 62.5% in patients who smoke cigarettes. Patients were classified into 3 groups based on the reasons for nonvaccination: documented patient refusal, not being addressed by a provider, and being documented as low risk despite the presence of a medical indication.

Conclusion: The 3 reasons for nonvaccination were vaccination not being addressed, misclassification of high-risk patients as low-risk patients for infection, and documented patient refusal. Providers overlooked vaccination more often in patients with asthma and cigarette use than in patients with diabetes. Patients seeing pharmacists were most likely to be vaccinated, whereas patients seeing physician assistants were least likely to be vaccinated. Pharmacists see patients to provide medication management and preventive care, whereas other providers treat more urgent conditions. Because indications are often overlooked and not addressed, pharmacists can play a larger role in identifying and vaccinating high-risk patients.
