The advantages and disadvantages of using administrative/claims data to estimate RSMR
have been well described.

The 30-day risk-standardized mortality rates (RSMRs
) decreased from 18.8 percent in 1995 to 15.8 percent in 2006.
Using longitudinal hospital-level data on RSC and RSMR
, this approach identified classes of hospitals based on their combined trajectory pattern of in-hospital cost and mortality over time.
On the other hand, this model's [X.sup.2]/df ratio and RSMR
values were within acceptable ranges (Wheaton, 1987).
Acute Myocardial Infarction (AMI): Hospital 30-Day, All Cause, Risk-Standardized Mortality Rate (RSMR
) Following AMI Hospitalization [accessed on March 15, 2013].
In this study, we performed a simulation experiment, which eliminates potential risk confounding, that tests the accuracy of five alternative outcome estimators: Observed-over-Expected, the Dimick-Staiger estimator, the Hierarchical Poisson (HP) estimator, the Risk-Standardized Mortality Rate (RSMR
), and the Moving Average (MA) estimator.
The final models fit the data very well for both treatment groups, exceeding standard criteria for good model fit; [chi square](218)=266.9; CFI=0.98; RSMR
= 0.04; [chi square](233) = 309.1; CFI = 0.97; RSMR
= 0.03, for the residential and outpatient samples, respectively.
