Political partisanship, laissez-faire attitudes, and Covid-19 behaviours and viewpoints in Canada and the United States
The Impact of Under Coding of Cardiac Severity and Comorbid Diseases on the Accuracy of Hospital Report Cards
CONTEXT: Hospital report cards usually are based on administrative discharge abstracts. However, cardiac severity and comorbidities generally are under-reported in administrative data. OBJECTIVE: We sought to determine how undercoding of cardiac severity and comorbidities affects the determination that some hospitals are high-mortality outliers. DESIGN: Simulations using retrospective data on 18,795 patients admitted with an acute myocardial infa…
Using disease risk estimates to guide risk factor interventions
Objective To assess the feasibility and acceptability of a patient workbook for self‐assessing coronary risk. Design Pilot study, with post‐study physician and patient interviews. Setting and subjects Twenty southern Ontario family doctors and 40 patients for whom they would have used the workbook under normal practice conditions. Interventions The study involved convening two sequential groups of family physicians: the first ( n =10) attended fo…
Factoring Socioeconomic Status Into Cardiac Performance Profiling for Hospitals
BACKGROUND: Critics of "scorecard medicine" often highlight the incompleteness of risk-adjustment methods used when accounting for baseline patient differences. Although socioeconomic status is a highly important determinant of adverse outcome for patients admitted to the hospital with acute myocardial infarction, it has not been used in most risk-adjustment models for cardiovascular report cards. OBJECTIVES: To determine the incremental impact o…
Effects of Socioeconomic Status on Access to Invasive Cardiac Procedures and on Mortality after Acute Myocardial Infarction
BACKGROUND: Universal health care systems seek to ensure access to care on the basis of need rather than income and to improve the health status of all citizens. We examined the performance of the Canadian health system with respect to these goals in the province of Ontario by assessing the effects of neighborhood income on access to invasive cardiac procedures and on mortality one year after acute myocardial infarction. METHODS: We linked claims…
Hospital volume, calendar age, and short term outcomes in patients undergoing repair of abdominal aortic aneurysms
OBJECTIVE: To determine, for abdominal aortic aneurysm surgery, whether a previously reported relationship between hospital case volume and mortality rate was observed in Ontario hospitals and to assess the potential impact of age on the mortality rate for elective surgery. DESIGN: Population based observational study using administrative data. SETTING: All Ontario hospitals where repair of abdominal aortic aneurysm as a primary procedure was per…
Canadian Health Care and the State
Canadian Health Care and the State
The contributors include prominent specialists in medical, military, and labour history, who provide valuable examinations of such issues as the ideological origins of the welfare state, the experience of the Canadian Army Medical Corps during the First World War, and the development of neuropsychology during the Second World War. Several essays are particularly relevant to contemporary concerns. A history of sexually transmitted diseases (STDs) …
Variation in Hospital Length of Stay for Acute Myocardial Infarction in Ontario, Canada
Unexplained variation in length of stay (LOS) following acute myocardial infarction (AMI) has been observed among American hospitals. We explored this phenomenon in the universal hospital care system of Ontario, Canada's largest province, analyzing general hospital discharge abstracts for all patients with a primary diagnosis of AMI. Case homogeneity was increased by excluding inter-hospital transfers, in-hospital deaths, patients with revascular…
Placing patients in the queue for coronary revascularization
A panel of 16 cardiologists and cardiac surgeons rated 438 case scenarios for the maximum acceptable delay prior to revascularization, using a scale with seven interventional time frames and two nodes for designating dubious or inappropriate cases. If consensus was defined as agreement by 12 or more panelists, only 1.4 percent of the case scenarios showed consensus on a single rating. Dividing the scale into three broad clinical categories (revas…

Private Practice
Canada's First Doctors' Strike
emergence and occupational success of Canada's medical profession was critically dependent on government. It was the provincial egislatures, after all, that enacted the licensing laws requested by medical lobbyists in the nineteenth century and also allowed doctors to incorporate self-governing provincial Colleges of Physicians and Surgeons. At the same time, various levels of government offered increasingly generous support for medical education…
