To provide immediate feedback to participants in Colorado’s accountable care organization (ACO) for Medicaid beneficiaries, program developers have chosen a handful of performance measures that will focus on program quality and cost containment, explains Laurel Karabatsos, deputy Medicaid director. The ACO is rapidly approaching its January 2011 launch date, and the development team has worked hard to garner support for an ACO that will provide health services for 60,000 Medicaid lives in the state. Karabatsos and Jerry Smallwood, Medicaid reform unit manager, will walk through Colorado’s ACO development process during “The Colorado Accountable Care Collaborative: Practical Lessons from an ACO,” a 45-minute webinar on September 29, 2010.
