Question: Why is the population in the 'Total' row sometimes larger than when I manually sum the hospital populations column?

Answer: Hospitals having populations of < 5 are supressed to protect patient privacy. The total row includes all patient populations for the category.


Observed Rate
The number of Cases divided by the Population at risk.
Risk-adjusted rates
 The estimated performance of hospitals if they had an ‘average’ casemix. The average casemix was estimated from the AHRQ national database (data from over 40 states). Most indicators are risk-adjusted for age, sex and 3M APR-DRG’s. Mortality measures use the 3M APR-DRG risk of mortality score and the utilization measures use the 3M APR-DRG severity score.

Observed Rate > Risk-adjusted Rate
Observed Rate < Risk-adjusted Rate
Observed Rate ≈ Risk-adjusted Rate
Mortality indicators: The hospital’s patient population for the condition or procedure has a higher risk of mortality due to its casemix (for example, older or a greater proportion of a higher-risk APR-DRG). The hospital’s patient population for the condition or procedure has a lower risk of mortality due to its casemix (for example, younger or a greater proportion of a lower-risk APR-DRG). The hospital’s patient casemix for the condition or procedure is similar to other hospitals’, suggesting that patient composition is not a contributing factor to the hospital’s performance for the mortality indicator.
Utilization indicators: The hospital’s population has a higher risk of receiving the procedure due to its demographic composition (for example, older or a greater proportion of a higher-risk gender). The hospital’s population has a lower risk of receiving the procedure due to its demographic composition (for example, younger or a greater proportion of a lower-risk gender). The hospital’s population is similar to other hospitals in demographic composition.
