A hospital's quality of care is generally assessed by a review of individual records. This study used unadjusted and risk-adjusted complication rates to measure the quality of care for hospitals that perform coronary artery bypass surgery or angioplasty. Hospitals differed greatly in their complication rates. Only a small percentage of this difference was due to differences in the risks that patients faced.
Hartz et al. (Wed,) conducted a observational in Coronary artery bypass surgery or angioplasty. Risk-adjusted complication rates vs. Unadjusted complication rates was evaluated on Complication rates. Hospital complication rates for coronary artery bypass surgery or angioplasty differed greatly, with only a small percentage of this difference attributable to patient risk factors.
