AFIX: The Four Components

The AFIX approach incorporates four key elements to improve immunization service delivery
  • Assessment of the healthcare provider's vaccination coverage levels and immunization practices

  • Feedback of results to the provider along with recommended strategies to improve coverage levels

  • Incentives to recognize and reward improved performance

  • eXchange of healthcare information and resources necessary to facilitate improvement


The purpose of AFIX is to move health care personnel from a state of unawareness about the problem (low immunization rates in their practice) to one in which they are

  1. aware, concerned and knowledgeable
  2. motivated to change
  3. ready to try new behaviors/strategies
  4. capable of sustaining these new behaviors.

AFIX as a quality assurance tool consists of assessing the provider’s vaccination coverage levels, feeding back that information along with recommending strategies for improvement, providing incentives to the provider to improve vaccination levels, and exchanging information among the providers within the community about performance and best-practices. This quality assurance measure is a proven and reliable tool for improving vaccination coverage levels in provider offices.
