Michigan Care Improvement Registry (MCIR)


MCIR is a Lifespan Registry!

The Michigan Care Improvement Registry (MCIR) was established by Public Act 91 of 2006 to include information about adult and childhood immunizations. It expanded the Michigan Childhood Immunization michiganRegistry previously established under Public Act 540 of 1996. MCIR collects reliable immunization information within a secure system that is accessible online to authorized users. MCIR benefits health care organizations, schools, licensed childcare programs, and Michigan citizens by consolidating immunization information from multiple providers. This helps to reduce vaccine preventable diseases, over immunization and allows providers to see up-to-date patient immunization history.

MCIR organizes the state into six regions that provide regional oversite for implementation, governance, evaluation, community assessment and reports, and training of private and public providers. The Genesee County Health Department serves as the coordinating agency for Region 4, a nine-county region that covers the thumb and part of the mid-michigan portion of the state of Michigan. Region 4 includes Bay, Genesee, Huron, Lapeer, Midland, Saginaw, Sanilac, Shiawassee, and Tuscola Counties.
