In 1994, Marshfield Clinic, located in central Wisconsin, began development of the Regional Early Childhood Immunization Network (RECIN), a real-time, Internet-based immunization registry.
Development of RECIN involved a unique collaborative effort between public and private providers in central Wisconsin.
A work group, formed in 1999 to design a school-specific module of RECIN, consisted of information technology professionals from RECIN, a Marathon County Health Department representative, a local pediatrician, and representatives from three public and private school districts.
A demographic integration program links student names to RECIN from a file created from the schools' existing databases.
The decrease in time occurred largely due to RECIN's ability to automatically identify overdue students.
