What are the significant clinical risk factors for in-hospital death after adult open heart surgery, and can risk-adjusted mortality identify centers with quality-of-care problems?
This study demonstrates that analyzing clinical risk factors and risk-adjusted mortality rates from a state registry can effectively identify cardiac surgical centers with serious quality-of-care problems.
Edward L. Hannan (1990) studied this question.
