Multicenter Study Comparative Study
Diagnosed hypertension in Canada: incidence, prevalence and associated mortality.
Hypertension is a leading risk factor for cardiovascular diseases. Our objectives were to examine the prevalence and incidence of diagnosed hypertension in Canada and compare mortality among people with and without diagnosed hypertension. ⋯ The overall prevalence of diagnosed hypertension in Canada from 1998 to 2008 was high and increasing, whereas the incidence declined during the same period. These findings highlight the need to continue monitoring the effectiveness of efforts for managing hypertension and to enhance public health programs aimed at preventing hypertension.

Low socioeconomic status is associated with poor cardiovascular health. We evaluated the association between socioeconomic status and the incidence of sudden cardiac arrest, a condition that accounts for a substantial proportion of cardiovascular-related deaths, in seven large North American urban populations. ⋯ The incidence of sudden cardiac arrest at home or at a residential institution was higher in poorer neighbourhoods of the US and Canadian sites studied, although the association was attenuated in Canada. The disparity across socioeconomic quartiles was greatest among people younger than 65. The association between socioeconomic status and incidence of sudden cardiac arrest merits consideration in the development of strategies to improve survival from sudden cardiac arrest, and possibly to identify opportunities for prevention.

Mortality associated with withdrawal of life-sustaining therapy for patients with severe traumatic brain injury: a Canadian multicentre cohort study.
Severe traumatic brain injury often leads to death from withdrawal of life-sustaining therapy, although prognosis is difficult to determine. ⋯ We observed significant variation in mortality across centres. This may be explained in part by regional variations in physician, family or community approaches to the withdrawal of life-sustaining therapy. Considering the high proportion of early deaths associated with the withdrawal of life-sustaining therapy and the limited accuracy of current prognostic indicators, caution should be used regarding early withdrawal of life-sustaining therapy following severe traumatic brain injury.

Whereas most studies have focused on euthanasia and physician-assisted suicide, few have dealt comprehensively with other critical interventions administered at the end of life. We surveyed cancer patients, family caregivers, oncologists and members of the general public to determine their attitudes toward such interventions. ⋯ Although the various participant groups shared the same attitude toward futile and ameliorative end-of-life care (the withdrawal of futile life-sustaining treatment and the use of active pain control), oncologists had a more negative attitude than those in the other groups toward the active ending of life (euthanasia and physician-assisted suicide).

Multicenter Study
Impact of death and dying on the personal lives and practices of palliative and hospice care professionals.
Background Working within the landscape of death and dying, professionals in palliative and hospice care provide insight into the nature of mortality that may be of benefit to individuals facing the end of life. Much less is known about how these professionals incorporate these experiences into their personal lives and clinical practices. Methods This ethnographic inquiry used semi-structured interviews and participant observation to elicit an in-depth understanding of the impact of death and dying on the personal lives of national key leaders (n = 6) and frontline clinicians (n = 24) involved in end-of-life care in Canada. ⋯ Clinical exposure to death and dying taught participants to live in the present, cultivate a spiritual life, reflect on their own mortality and reflect deeply on the continuity of life. Interpretation Participants reported that their work provided a unique opportunity for them to discover meaning in life through the lessons of their patients, and an opportunity to incorporate these teachings in their own lives. Although Western society has been described as a "death-denying" culture, the participants felt that their frequent exposure to death and dying was largely positive, fostering meaning in the present and curiosity about the continuity of life.
