Canadian provinces should adopt a patient charter of rights with independent enforcement as part of the move to patient-centered care, argues an analysis article in CMAJ (Canadian Medical Association Journal). A properly designed patient charter of rights can help patients resolve concerns and complaints easily and cost-effectively, through an independent ombudsman or commissioner. An effective patient charter contains clearly articulated patient rights – many of which are already...

Patients with advanced chronic obstructive pulmonary disease (COPD) and shortness of breath found that opioids provided relief and improved their quality of life, states an article in CMAJ (Canadian Medical Association Journal).

The notion that senior drivers have higher rates of crashes because they are poorer drivers is largely a misconception, according to a commentary in CMAJ (Canadian Medical Association Journal). The overrepresentation of seniors in fatal crashes is mainly due to their "frailty" – "the age-related increase in the probability of dying as a result of a crash," writes Dr. Ezra Hauer, professor emeritus, Department of Civil Engineering, University of Toronto. "Frailty as a cause of...

The Canadian Medical Association Journal (CMAJ) is a peer-reviewed medical journal published by the Canadian Medical Association (CMA). The journal’s establishment likely would not have been without the foresight of Andrew Macphail, chair of the history of medicine at McGill University and editor of the Montreal Medical Journal. At the 1907 annual meeting, he argued that “without a journal to express its views and record its proceedings the association would have little impact.”  With...
