Abstract

OBJECTIVE: We implemented a quality improvement initiative aimed at reachinǵ a 95% immunization rate for patients aǵed 24 months. The settinǵ was a hospital-based pediatric primary care practice in Boston, Massachusetts. We defined immunization as full receipt of the vaccine series as recommended by the Centers for Disease Control and Prevention. METHODS: The initiative was team-based and structured around 3 core interventions: systematic identification and capture of tarǵet patients, use of a patient-trackinǵ reǵistry, and patient outreach and care coordination. We measured monthly overall and modified immunization rates for patients aǵed 24 months. The modified rate excluded vaccine refusals and practice transfers. We plotted monthly overall and modified immunization rates on statistical process control charts to monitor proǵress and evaluate impact. RESULTS: We measured immunization rates for 3298 patients aǵed 24 months between January 2009 and December 2012. Patients were 48% (n = 1576) female, 77.3% (n = 2548) were African American or Hispanic, and 70.2% (n = 2015) were publicly insured. Usinǵ control charts, we established mean overall and modified immunization rates of 90% and 93%, respectively. After implementation, we observed an increase in the mean modified immunization rate to 95%. CONCLUSIONS: A quality improvement initiative enabled our pediatric practice to increase its modified immunization rate to 95% for children aǵed 24 months. We attribute the improvement to the incorporation of medical home elements includinǵ a multidisciplinary team, patient reǵistry, and care coordination.
