Unwarranted Variation: Expanding the Agenda for Rebuilding the Health Care system in Louisiana January 16, 2007 REDESIGNING 10 th Annual Health Care Forum on Health Care Effectiveness LSU

2 Backdrop

3 Agenda  Unwarranted Variations  From Regions to Hospitals in Baton Rouge and New Orleans  Pushing the envelope

4 Unwarranted Variation Defined  Unwarranted? Variations that cannot be explained by: –Illness, need, dictates of evidence based medicine or patient preferences  Categories of variation –Effective and safe care –Preference sensitive care –Supply sensitive services  Causes and remedies differ for each category
