Monitoring and measuring office processes and outcomes is a critical part of quality improvement work. Overall outcomes, such as improved vaccine coverage rates, are important to measure, but process measures, such as the rate of missed opportunities to vaccinate, can provide much needed information on whether interventions are being implemented consistently and reliably.
The measures set that was developed in the Improving Childhood Immunizations Project is included in Appendix B for reference, adaptation and use in your practice.
