AFIX Assessment: Hybrid Method
What is the Hybrid Assessment Method?
The Hybrid method for assessing practice-based immunization coverage levels is a combination of Lot Quality Assurance (LQA) sampling and the more traditional method used for assessment.
The Hybrid Assessment method is a screening tool to help identify if a provider’s immunization coverage level is above or below a specific threshold. The Hybrid method uses small sample sizes so it takes less time to conduct; unfortunately though, it does not have diagnostic capabilities to determine why a provider might have low immunization coverage levels. Please keep in mind that the Hybrid method is not designed to determine the actual immunization coverage level for the practice but to determine if the practice is performing above or below a specific level.
The following is a list of terms that are used throughout the protocol.
The standard at which the provider is evaluated against. If the threshold level is set at 70%, then the assessment will determine if the provider has immunization coverage level above or below 70%. Use existing information to determine the appropriate threshold level for your area (for example: NIS estimates, public health center or private provider assessment information).
The number of children in the sample allowed to be not up-to-date (UTD). If the number of children in the sample not UTD exceeds the reference number, then the provider has an immunization coverage level below the threshold level.
