Table 4.

Relative ability of different quality measures from 2008-09 to discriminate future (2010) risk-adjusted complications and explain variation in hospital-level complication rates.

Hospital Rankings (2008-09)	Risk-adjusted complications in 2010
Hospital Rankings (2008-09)	Odds ratio (95% CI)	Odds ratio (95% CI)	Proportion of hospital-level variation explained
Quality measure	2-star vs. 3-star hospitals	1-star vs. 3 star hospitals	Proportion of hospital-level variation explained
Hospital volume	0.93 (0.47 to 1.85)	0.85 (0.43 to 1.68)	0%
Risk-adjusted complication rates	1.27 (0.66 to 2.44)	1.56 (0.84 to 2.91)	28%
Risk- and reliability adjusted complication rates	1.37 (0.71 to 2.61)	1.65 (0.88 to 3.10)	47%
Composite measure	1.26 (0.7 to 2.25)	1.99 (1.14 to 3.47)	89%
