To further evaluate contemporary risk and practice patterns in acute myocardial infarction (AMI), 402 consecutive patients with AMI between July 1, 1988, and June 30, 1989 were studied. The clinical investigations, medical therapy and outcome of patients aged greater than or equal to 70 years (n = 132; group 1) were compared with patients aged less than 70(More)
OBJECTIVE To define contemporary age- and sex-related mortality risks and patterns of medical practice in acute myocardial infarction (AMI). DESIGN Retrospective comparison of demographic and clinical variables, including the use of proven effective AMI medical therapy, among AMI patients cohorts from 1987 to 1992. PATIENTS/SETTING Of a total of 2,070(More)
OBJECTIVE To review the changing clinical profile of isolated coronary artery bypass graft (CABG) surgery patients at the University of Alberta Hospitals during the past two decades. DESIGN Data were obtained retrospectively by review of patients' hospital charts and cardiologists' charts. The three patient cohorts consisted of the first 411 consecutive(More)
A retrospective study was carried out to assess the feasibility of computer-assisted prognostication by discriminant analysis and the Bayesian classification procedure based on clinical information collected on patients with acute myocardial infarction. The overall accuracy was 94.2% in predicting hospital death but the prediction of late death after(More)
BACKGROUND In February 1994 Alberta Health announced a three-year business plan for the radical restructuring of the health care system in Alberta. The business plan outlined large reductions in funding for acute hospital care spending and the establishment of 17 Regional Health Authorities (RHAs). OBJECTIVES The objectives of this study are to describe(More)
A system for patient classification by types of care (referred to in this article as the PCTC system) was developed. The objectives of the system are to improve placement decisions for long-term care patients and to provide information that would be useful for planning and resource allocation in the long-term care field. The PCTC system attempts to resolve(More)
OBJECTIVE Between 1994/95 and 1996/7, the healthcare system in Alberta underwent a radical transformation that saw the regionalization of service delivery and a reduction in overall healthcare funding. The aim of this study is to examine trends in utilization and associated post-operative complications and readmissions for two procedures, total hip(More)
The in-hospital management and risk of death of 101 patients 70 years of age or older with acute myocardial infarction in 1987 (group 1) were compared with management and risk for 106 temporally matched patients less than 70 years old (group 2). In group 1, 49% had histories of previous myocardial infarction, compared to 25% in group 2 (P less than 0.001),(More)
