The impact of a quality improvement continuing medical education intervention on physicians’ vaccination practice: a controlled study

This study investigated the impact of a longitudinal quality improvement continuing medical education (CME) intervention on influenza and pneumococcal vaccination rates for patient populations at high-risk or aged ≥ 65. An observational cohort design with a propensity score to adjust for vaccine eligibility between the intervention and control cohorts was utilized to assess the impact of the intervention among primary care physicians. The intervention was a three-stage quality improvement initiative with CME learning activities. Stage A was an assessment of practice to establish baseline performance. Stage B was participation in learning interventions and individualized action planning for practice change, and Stage C was practice reassessment. Data were also collected for a control group of clinicians who did not participate during the same period. One hundred primary care physicians completed all 3 intervention stages10/14 – 7/15. Altogether, 361,528 patient records of vaccine receipt were compared for those physicians who completed the educational intervention and those who did not. The percentage of physicians’ adult patients receiving influenza or pneumococcal vaccination increased on all measures. The difference between intervention versus control groups was 3.4% higher for influenza ≥ 65 years, 2.1% for influenza high-risk, 0.6% for pneumococcal ≥ 65 years, and 1.4% for pneumococcal high-risk. These results show that physician participation in a quality improvement CME initiative can be an effective strategy to improve vaccination administration. The findings strengthen the evidence that CME learning interventions can advance quality improvement goals and more favorably affect physicians’ practice when educational strategies are utilized.
