The GAP projects
After initial development at the University of Michigan Health System,7 the ACC AMI GAP projects included a 10-hospital pilot study9 in Southeast Michigan in 1999, a 5-hospital project in Flint and Saginaw10 in 2001, and an 18-hospital expansion project8 in Southeast Michigan in 2002. The AMI GAP projects were conducted in partnership with the MPRO, local health coalitions, the ACC, and local nonprofit or government hospitals, of which most were teaching hospitals. The GAP fosters systems-based
Results
Of the 2857 patients studied, 47.9% (n = 1368) were in the baseline or pre-GAP cohort, whereas 52.1% (n = 1489) were in the post-GAP cohort. Tertile 1 included 418 pre-GAP patients and 445 post-GAP patients; tertile 2 included 454 pre-GAP patients and 525 post-GAP patients; tertile 3 included 496 pre-GAP patients and 519 post-GAP patients. Table I reports patient characteristics in each cohort by tertile. The average patient age was 76.3 years. Patients in all 3 tertiles were similar with
Discussion
The results of this study suggest an association between utilization of the standard discharge contract in the context of GAP and mortality at 1 year in Medicare beneficiaries hospitalized for AMI (Figure 3, Table III). Mortality at 1 year was estimated to be 6.0% lower among patient populations treated at hospitals where the discharge contract was most often used. None of the 33 participating hospitals achieved >61.1% utilization of the discharge contract; and therefore, the potential
