Sensitivity analysis that replaces the receipt of PTCA for the receipt of CABG as the dependent variable indicates that, although adjusted PTCA rates increased markedly from the pre- to the postperiod for each racial and ethnic cohort in both PHQID and non-PHQID hospitals, no DID and DIDID estimates were significant (see Appendix SA4).
study employed a similar DIDID estimation strategy (examining whether minority patients experienced a decrease in CABG rates, relative to whites, in New York (which had the public reporting program) relative to comparison states, before and after the public reporting program began).
Second, the DIDID estimates in the CABG analysis are somewhat imprecise, making inference uncertain and potentially subject to Type II error.
