Michigan represented All Kids Count's largest, and in many ways, most complex project. At the project's conclusion in June 2000, MCIR reported impressive statistics: it included 1.7 million child records and 14 million immunization records. Eight hundred of the 1,600 enrolled providers were active users, and 500 of them regularly queried the registry for reports. As many as 200 users accessed MCIR in the course of a business day.
The sheer volume of data and number of providers, compounded by the large geographic region of the state, could have been paralyzing.
Instead, a regional approach that resulted in responsiveness and adaptability in developing, managing, marketing, and implementing the state-developed and maintained technology, resulted in a highly functional state registry poised for success.
