CALIFORNIA IMMUNIZATION REGISTRY

Health Plan Users

Health plans (HPs), independent practice associations (IPAs), and medical groups (MPs) can submit member lists to CAIR and receive back matched patient immunization histories to help them complete their HEDIS (Healthcare Effectiveness Data and Information Set) measures.

Note: To assist HPs, several new fields have been added to the HEDIS report. Please see the updated HEDIS report (PDF) for more information.

Note to HEDIS Requestors about File Size (3/13/2020) (PDF)

It has come to our attention that many HPs are sending very large files containing multiple name variants for the same member. While we understand the rationale for doing this is to increase the probability of matching member patients in CAIR2, it is also causing the HEDIS matching process to take much longer as larger files take more time to process. We are therefore asking HPs who submit member files with multiple variant names to take steps to reduce their input file size in subsequent HEDIS requests by eliminating all non-matching variants member names when a member is successfully matched. Reducing file sizes will benefit everyone as HPs will get their reports more quickly. Also, beginning 3/16/2020, CAIR2 will no longer process patient input files with >1M rows to reduce overall processing time.

Complete the forms below to enroll in the HEDIS process and format and submit your files according to the HEDIS Patient Match Specifications document below. Representatives of these groups can also be given read-only access to CAIR that allows individual patient lookup. To request a CAIR read-only user account, contact Michael Powell (michael.powell@cdph.ca.gov). If you are interested in patient match reports from CAIR San Joaquin, contact the Local User Support Contact in those regions.
