RE: O/E Model
The Midas Model is copyrighted, but I think I can share the common concepts, which may be helpful to those that were requesting info about Mortality Reporting.
Bottom Line is what all of us have always stated, acuity matters, and need to look deeper than CC/MCC Capture.
APR DRG
Description of the APR DRG.
# Cases Number of cases that were assigned this APR DRG at the facility.
Observed Mortality Observed number of deaths among patients with the APR DRG at the facility.
Expected Mortality Expected number of deaths for the APR DRG. To calculate this value, the facility's
volume of encounters for each mortality-risk level (1–4) is divided by the CDB
volume of encounters for that level, and then multiplied by the CDB observed
number of deaths for the same level.
Mortality O/E Ratio The facility’s observed number of deaths divided by the expected number of
deaths. A value less than 1.0 is better than expected. A value greater than 1.0 is
worse than expected.
When interpreting the report, you should take into account the number of cases.
O/E Percentile Percentile for the facility's O/E ratio value compared with the CDB mean
performance.
# of Sites Number of participating facilities in the comparative pool.

Comments
Our Database analyst that deals with MIDAS told me that up until now MIDAS has used APR methodology but they just changed to their own (more specific) methodology. She gave me a pile of information to sort through but I have not gotten to that yet.
Is what you referring to the old or new methodology?
Thanks!
