REVIEWSPharmacist Involvement with Immunizations: A Decade of Professional Advancement
Section snippets
Decade of Postgraduate Training
Washington State pharmacists represented the first organized movement in pharmacist-administered immunizations. Jacqueline S. Gardner, MPH, PhD, a non-pharmacist epidemiologist and faculty member at University of Washington School of Pharmacy, provided much of the initial support and development for the initiative. In 1994 the Centers for Disease Control and Prevention (CDC) was highlighting childhood immunization disparities and missed opportunities for vaccination in the public health
Academia Begins Closing Educational Gap
While postgraduate training in immunizations for pharmacists has produced immediate success in practice, academic institutions have been slower to respond with formalized vaccine and public health training despite a long-standing call for such training. A 1965 American Association of Colleges of Pharmacy (AACP) report titled Public Health in the Curricula of Colleges of Pharmacy stated that pharmacy schools should “upgrade the public health components of their curricula.”16 Froh17 reported in
Support from Medicine
External factors, including support from the public health community, have also moved the profession forward. In 2002, a joint position paper on the pharmacist's scope of practice was published by the American College of Physicians—American Society of Internal Medicine (ACP—ASIM).22 Among several position statements in the document, one directly addressed the pharmacist's emerging role in immunization: The ACP—ASIM “supports the use of the pharmacist as immunization information source, host of
Training Results in Positive Activity
Neuhauser and colleagues23 at the University of Houston College of Pharmacy compared the demographics, professional activities, and job satisfaction of immunization-certified and other pharmacists in Texas. This cross-sectional study found that significantly more certified pharmacists were involved in immunizations as an advocate, partner (hosting immunization providers in the practice), and provider (99%) when compared with noncertified pharmacists (24%; P < .001). Of those certified, 74%
Early Literature Predicts Success
An important study conducted by Grabenstein and colleagues envisaged the success pharmacists would have as immunizers.24 This randomized controlled trial explored the persuasiveness of pharmacists in advocating that patients seek immunization from a third party (i.e., health department or physician) source. Vaccination rates among those receiving the mailed vaccine advice were compared with those of a control group that received a poison-prevention letter. Unvaccinated people encouraged by the
Pharmacists as Immunization Advocates
A 1999 study of 655 patients considered at high risk for contracting influenza were sent an information packet by the pharmacy team at a rural clinic in New York.26 At that time, New York's pharmacy practice act did not explicitly allow pharmacists to administer vaccine. However, a pharmacy team conducted a chart review to identify high-risk patients, collected patient information, screened patients for appropriateness of vaccination, compiled the mailing to targeted patients, conducted patient
Studies of Patient Perceptions
Published studies on patient perceptions of pharmacist-administered vaccinations are summarized in Table 3. A 2001 report by Grabenstein et al.29 described the characteristics of people vaccinated by pharmacists in pharmacies. Patient surveys collected in January 1999 from 21 pharmacies in 17 cities in 10 states were analyzed. A total of 8,266 vaccine recipients were reported at these pharmacies, and 1,730 (21%) surveys were completed for analysis. Both rural and urban pharmacies participated.
Health-System Pharmacists and Immunizations
Even though community pharmacy—based immunizations receive the greatest amount of attention in the pharmacy literature, hospital and health-system pharmacists have a comparably important role to play, and have done an admirable job of documenting their efforts over the past decade. David Fedson, MD, in a 1990 letter to the editors of the American Journal of Hospital Pharmacy, commented, “Although many patients cared for in hospitals meet well-accepted criteria for immunization, physicians often
Pharmacists Increase Overall Vaccination Rates
Perhaps the most important unsolved research problem is the evaluation of the effect of pharmacist-administered vaccinations on overall vaccination rates. A 2004 study compared influenza vaccination rates in states where pharmacists were or were not authorized to administer vaccines during the study period (1995–1999).40 The Behavioral Risk Factor Surveillance System (BRFSS), a telephone survey conducted annually by CDC to assess overall health risks and activities over the previous 12 months,
Looking Ahead to the Next Decade
Pharmacists are well-accepted by the public as immunizers, and pharmacies are logical sites for vaccine clinics. As pharmacy begins its second decade in immunization administration and advocacy, institutional pharmacists should continue to capitalize on a strong foundation of eliminating missed opportunities for vaccination of patients before discharge. Community pharmacists should continue to promote the unique access they provide to vaccines. Community pharmacists should also partner with
Conclusion
The decade of 1995 through 2004 was one of monumental advancement in pharmacist involvement with immunizations. Because of the convergence of practitioners eager to prove their skills in nondispensing activities with that of readily available payment sources for immunization services, we believe that the national movement toward pharmacist-administered immunizations may prove to be the most significant catalyst in moving the profession beyond dispensing to direct patient care. Whether serving
