Y and N indicate statistically significant gains and losses, respectively.
MA*During included but coefficient not reported. All specifications and means are weighted using discharge weights.
All specifications include hospital fixed effects and time fixed effects for 2004 to 2008, quarterly.
Risk adjusters include six sets of risk adjustment variables: demographic characteristics, the number of diagnoses on the discharge record, individual components of the Charlson Score measure of comorbidities, AHRQ comorbidity measures, All-Patient Refined (APR)-DRGs, and All-Payer Severity-adjusted (APS)-DRGs. See Appendix 2.
Regressions in this table estimated in the sample of nonelderly discharges.
