“…Overall variable agreement averaged Ͼ90% for all variables in all samples, and exceeded 0.41, indicating at least good agreement. 15,16 Agreement on the quality indicators exceeded 95% for all indicators in all samples, with exceeding 0.88, indicating excellent agreement for all indicators. 19 For all variables used in the present study, the definitions used during the abstraction were consistent across time periods.…”

“…Although some of the data from these projects have been published, [15][16][17][18] a longitudinal assessment including all 4 time periods has not been available. The simultaneous study of all of these projects thus provides a unique opportunity to assess long-term trends in large community-based populations of older patients hospitalized with AMI from the health system perspective.…”

Background-Because of the health impact of acute myocardial infarction (AMI), substantial resources have been dedicated to improving AMI care and outcomes. Long-term trends in the clinical characteristics, quality of care, and outcomes for AMI over time from the health system perspective in geographically diverse populations are not well known. Methods and Results-The present study included 20 550 Medicare patients aged Ն65 years hospitalized in 4 US states (Alabama, Connecticut, Iowa, Wisconsin) with the confirmed primary discharge diagnosis of AMI in 4 periods: 1992-1993 (nϭ10 292), 1995 (nϭ5566), 1998 -1999 (nϭ2413), and 2000 -2001 (nϭ2279). With the use of standard quality indicator definitions, treatment of ideal candidates with aspirin and ␤-blockers within 24 hours after presentation, ␤-blockers, and angiotensin-converting enzyme inhibitors at discharge was assessed. Multivariable models were constructed to calculate adjusted 1-year mortality.

“…We harmonized the definition of "ideal" so that data elements common to both databases could be used in an identical fashion. 19,23 We assessed mortality after hospital admission by linking the clinical data sets to the Medicare enrollment database and billing records in the United States, and the Ontario Registered Persons Database in Canada, which contains information on the vital status of all Ontario residents. 24,25 Risk-standardized mortality rates at 30 days were chosen as our primary mortality outcome and riskstandardized mortality rates at 1 year and 3 years were chosen as secondary outcomes.…”

Background— Previous comparisons of acute myocardial infarction (AMI) treatment between the United States and Canada are limited because they compared selected patients from randomized trials, used administrative data that lacked clinical detail, or did not consider regional differences in AMI treatment. Methods and Results— We compared medication use, invasive cardiac procedure use, and 30-day risk-standardized mortality rates of 38 886 fee-for-service Medicare beneficiaries hospitalized with AMI in the United States and 5634 similarly aged patients in Ontario, Canada, from 1998 and 2001. Baseline characteristics and illness severity across the US regions and Ontario were not substantially different. Cardiac catheterization use in AMI patients was significantly higher in the United States compared with Ontario (38.7% versus 16.8%, P <0.001), but significant regional variations existed, in which the northeastern United States had significantly lower utilization rates (25.6%) compared with other US regions. β-Blocker use among ideal candidates was highest in the northeastern United States (77.6% versus 69.7% in the United States as a whole, P <0.001) and angiotensin-converting enzyme inhibitor use was highest in Ontario (69.1% versus 58.2% in the United States, P <0.001). Risk-standardized mortality rates at 30 days were not substantially different across the regions. Conclusions— Previous studies have suggested a clear divergence in invasive cardiac therapy for AMI patients between the United States and Canada on the basis of health care financing and structural differences. Our findings of similar treatment patterns in the northeastern United States and Ontario suggest that regional practices may have a greater impact on treatment patterns than the respective health care delivery systems.

“…Between the Cooperative Cardiovascular Project (1994 to 1995) and the National AMI Project Baseline (1998 to 1999), the mean time to fibrinolysis among eligible patients improved by 7 minutes and the time to PCI by 12 minutes. 7 Between 1998 to 1999 and 2000 to 2001, fibrinolysis times increased slightly (by 4 minutes, to a median of 45 minutes), whereas time to PCI continued to improve (by 19 minutes, to a median of 107 minutes). 6 Thus, although data on national trends in the timeliness of reperfusion have been encouraging, there are clearly persistent gaps in the provision of reperfusion therapy that justify ongoing measurement.…”
