    BACKGROUND

    Quality improvement in primary care has focused on improving adult immunization.

    OBJECTIVES

    Test the effectiveness of a step-by step, evidence-based guide, the 4 Pillars™ Immunization Toolkit, to increase adult pneumococcal vaccination.

    DESIGN

    Randomized controlled cluster trial (RCCT) in Year 1 (6/1/2013–5/31/2014) and a pre-post study in Year 2 (6/1/2014–1/31/2015) with data analyzed in 2016. Baseline year was 6/1/2012–5/31/2013. Demographic and vaccination data were derived from de-identified EMR extractions.

    SETTING

    25 primary care practices stratified by city (Houston, Pittsburgh), location (rural, urban, suburban) and type (family medicine, internal medicine), randomized to receive the intervention in Year 1 (n=13) or Year 2 (n=12).

    PARTICIPANTS

    A cohort of 18,107 patients ≥65 years at baseline with a mean age of 74.2 years; 60.7% were women, 16.5% were non-white and 15.7% were Hispanic.

    INTERVENTION

    The Toolkit, provider education, and one-on-one coaching of practice-based immunization champions. Outcome measures were 23-valent pneumococcal polysaccharide vaccine (PPSV) and pneumococcal conjugate vaccine (PCV) rates and percentage point (PP) changes.

    RESULTS

    In the RCCT, all intervention and control groups had significantly higher PPSV vaccination rates with average increases ranging from 6.5–8.7 PP (P<0.01). The intervention was not related to higher likelihood of PPSV vaccination. In the Year 2 pre-post study, the likelihood of PPSV and PCV vaccination was significantly higher in the active intervention sites than the maintenance sites in Pittsburgh, but not in Houston.

    CONCLUSION

    In a randomized controlled cluster trial, both intervention and control groups increased PPSV among adults ≥65 years. In a pre-post study, private primary care practices using the 4 Pillars™ Immunization Toolkit significantly improved PPSV and PCV uptake compared with practices that were in the maintenance phase of the study.
