Using the 4 Pillars Practice Transformation Program to Increase Pneumococcal Immunizations for Older Adults: A...

Area of Science:

• Public Health and Preventive Medicine
• Healthcare Quality Improvement
• Vaccination Strategies

Background:

• Adult pneumococcal vaccination rates remain suboptimal, necessitating effective interventions in primary care settings.
• The 23-valent pneumococcal polysaccharide vaccine (PPSV) and pneumococcal conjugate vaccine (PCV) are crucial for preventing pneumococcal disease in older adults.

Purpose of the Study:

• To evaluate the effectiveness of the 4 Pillars Practice Transformation Program, an evidence-based guide, in increasing adult pneumococcal vaccination.
• To assess the impact of provider education and immunization champion coaching on vaccination rates.

Main Methods:

• A randomized controlled cluster trial (RCCT) in Year 1 and a pre-post study in Year 2 involving 25 primary care practices.
• Practices were stratified by location, type, and metropolitan area, and randomized to intervention or control/maintenance groups.
• Data collected via deidentified electronic medical record extractions included demographic and vaccination status for individuals aged 65 and older.

Main Results:

• In Year 1 (RCCT), PPSV vaccination rates significantly increased in both intervention and control groups (6.5–8.7 percentage points).
• The intervention itself was not directly associated with a greater likelihood of PPSV vaccination in Year 1.
• In Year 2 (pre-post), practices actively engaged in the 4 Pillars Program showed significantly higher PPSV and PCV uptake compared to maintenance sites in Pittsburgh, but not Houston.

Conclusions:

• The 4 Pillars Practice Transformation Program demonstrates potential for improving pneumococcal vaccination rates in primary care.
• Active engagement with the program appears more effective than maintenance phases for enhancing vaccine uptake.
• Further research may be needed to understand regional variations in program effectiveness.
