Identifying Missed Opportunities for the Pneumococcal Conjugate Vaccine (PCV13)

Abstract

Background: The recommendation for the pneumococcal conjugate vaccine (PCV13) in adults 65 years and older is recent, and the dosing schedule of PCV13 and the pneumococcal polysaccharide vaccine (PPSV23) can be complex in this population. Objective: The authors assessed the rate of PCV13 immunization in patients 65 years of age and older and identified barriers that contributed to missed opportunities for PCV13. Methods: This retrospective review evaluated outpatient Veterans age 65 years or older who did not receive PCV13 at a scheduled primary care appointment despite an electronic reminder. Investigators recorded any documented reason for the patient not receiving PCV13. Results: The rate of PCV13 immunizations administered during the primary care visit study period was 37% (89 of 239 PCV13 eligible patients). Of the 150 patients identified who did not receive PCV13, 92% were not offered the vaccine, 6.7% declined vaccination, and 0.7% reported an allergy to vaccination. Electronic immunization records revealed that 48 of the 150 patients who did not receive PCV13 at their clinic appointment did receive PCV13 later the same year. Most patients received PCV13 in influenza vaccine season on the same day as receiving the influenza vaccine. Conclusion: The main barrier identified was not offering the vaccination during primary care visits. Pneumococcal vaccine administration was delayed until the influenza vaccine season in a significant portion of patients. This unexpected finding represents a target for education: ensuring health care professionals are reminded that PCV13 is not a seasonal vaccine like the influenza vaccine, but should be offered throughout the year.
