Abstract
INTRODUCTION: In 2014, the Advisory Committee on Immunization Practices (ACIP) of the US Centers for Disease Control and Prevention (CDC) recommended 13-valent pneumococcal conjugate vaccine (PCV13) followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23) for all adults aged ≥ 65 years, with a commitment to revisit the recommendation for PCV13 because of declining vaccine-type disease. The Evidence-to-Recommendation framework used by the ACIP includes review of evidence regarding feasibility and stakeholder acceptability, but no surveys of vaccinator preferences have been published in the literature. METHODS: Physicians (N = 700), physician assistants (N = 100), pharmacists (N = 100), and nurse practitioners (N = 100) who recently prescribed, administered, or recommended adult pneumococcal vaccine were surveyed in March 2018. Object-case best-worst scaling was used to assess preferences among potential recommendation scenarios: retaining the then-current 2014 recommendation without a scheduled re-evaluation, retaining with a scheduled re-evaluation, revising PCV13 to Category B (retaining PPSV23 as Category A), removing PCV13 (retaining PPSV23 as Category A), and removing both PCV13 and PPSV23. RESULTS: Providers' most preferred recommendations were retaining the 2014 recommendation with another planned re-evaluation (52.6%) and retaining the then-current recommendation without planned re-evaluation (40.0%). Few preferred changing PCV13 to Category B (3.2%), removing PCV13 (3.7%), or removing both pneumococcal vaccines (0.5%). CONCLUSIONS: The majority of vaccinators surveyed preferred to retain the 2014 recommendation, either with another scheduled reassessment or indefinitely. FUNDING: Pfizer, Inc.
