Unadjusted Trends in Mortality for Surgical Admissions by Hospital Financial Health Quartile

Note. The Accreditation Council for Graduate Medical Education duty hour regulations were implemented on July 1, 2003. Prereform year 3 (Pre-3) included academic year 2000–2001 (July 1, 2000, to June 30, 2001); prereform year 2 (Pre-2), academic year 2001–2002; prereform year 1 (Pre-1), academic year 2002–2003; postreform year 1 (Post-1), academic year 2003–2004; and postreform year 2 (Post-2), academic year 2004–2005. No significant divergence was found in the degree to which mortality changed from prereform year 1 to either postreform year any group. Significance levels assess whether trend from prereform year 1 to postreform years 1 and 2, respectively, differed for less versus more financially healthy hospitals
