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

Implications of Katrina in Regards to Unwarranted Variation
The impact of Hurricane Katrina on the heath care infrastructure within New Orleans presents a unique opportunity to design out unwarranted variation.

Health Dialog Project for the Louisiana Health Care Redesign Collaborative
1. Create a unified data set combining pre-Katrina:• Commercial data • Medicaid data• Medicare data• Uninsured data• VA data
2. Analyze integrated data-set (at patient, market areas – tertiary and primary, and payer (including none)
• Disease prevalence/patterns• Utilization patterns• Cost patterns• Quality patterns
3. Examine geographic differences both within Louisiana, and compared to national benchmarks
4. Data warehouse will serve as an important tool as decisions are made regarding what and where to rebuild, as well as an ongoing asset to be updated with current data
