Care Variability Across Regions

Screen Shot 2018-08-09 at 2.38.19 PM.png

Based on 2016 MEDPAR Inpatient Data we calculated a variability score using total charges as proxy.  Amongst hospitals in the 5 major DRGs shown:

  • The Pacific region consistently shows the highest variability.
  • The East and West South Central regions consistently have the least variability.
  • LOS is a key driver of claim level variability within a DRG.

We reviewed correlation to other variables and found region variances were not related to total volumes, average charges, or length of stay.
