Exploring attitudes toward physician-assisted death in patients with life-limiting illnesses with varying experiences of palliative care: a pilot study.

BACKGROUND: On February 6th, 2015, the Supreme Court of Canada ruled that competent adults suffering intolerably from a grievous and irremediable medical condition have the right to the assistance of a physician in ending their own lives, an act known as physician-assisted death, and later defined as medical assistance in dying, allowing for provision by a physician or a nurse practitioner. As of June 6th, 2016, this is no longer illegal across Canada. There is strong support amongst the general population for physician-assisted death, however there is no recent data on the attitudes of terminally ill patients. Our main objective was to gain information on terminally ill patients' general and personal attitudes toward physician-assisted death. METHODS: This is an exploratory pilot study. We surveyed three groups of patients with life-limiting diagnoses: one with new referrals to palliative care; one with no palliative care involvement; and one with prior and ongoing management by a palliative care team. Respondents were surveyed twice, approximately two weeks apart, and rated their general attitudes toward physician-assisted death and the hypothetical consideration of physician-assisted death for oneself on a five-point Likert scale at baseline and follow-up. Respondents with new referrals to palliative care were surveyed before and after palliative care consultation. This study was approved by The Western University Health Sciences Research Ethics Board and Lawson Health Research Institute. RESULTS: We surveyed 102 participants, 70 of whom completed both surveys (31% dropout rate). Participants in all groups predominantly responded between somewhat agree (4 on a 5-point Likert scale) and strongly agree (5 on the Likert scale) when asked about their general attitude toward physician-assisted death. Patients with prior palliative care involvement reported the highest average ratings of hypothetical consideration of physician-assisted death for oneself on a 5-point Likert scale (3.4 at baseline; 3.9 at follow-up), followed by patients with a new palliative consultation (3.2 at baseline; 3.3 at follow-up), and patients with no palliative involvement (2.6 at baseline; 2.9 at follow-up). CONCLUSIONS: Given the preliminary results of this pilot study, we can conclude that terminally ill patients generally agree that physician-assisted death should be available to patients with life-limiting illnesses. Furthermore, descriptive data show a trend for higher hypothetical consideration of physician-assisted death in those patients with prior and ongoing palliative care involvement than patients without palliative involvement. Responses in all groups remained fairly consistent over the two-week period.

Cardiovascular disease after Escherichia coli O157:H7 gastroenteritis.

BACKGROUND: Escherichia coli O157:H7 is one cause of acute bacterial gastroenteritis, which can be devastating in outbreak situations. We studied the risk of cardiovascular disease following such an outbreak in Walkerton, Ontario, in May 2000. METHODS: In this community-based cohort study, we linked data from the Walkerton Health Study (2002-2008) to Ontario's large healthcare databases. We included 4 groups of adults: 3 groups of Walkerton participants (153 with severe gastroenteritis, 414 with mild gastroenteritis, 331 with no gastroenteritis) and a group of 11 263 residents from the surrounding communities that were unaffected by the outbreak. The primary outcome was a composite of death or first major cardiovascular event (admission to hospital for acute myocardial infarction, stroke or congestive heart failure, or evidence of associated procedures). The secondary outcome was first major cardiovascular event censored for death. Adults were followed for an average of 7.4 years. RESULTS: During the study period, 1174 adults (9.7%) died or experienced a major cardiovascular event. Compared with residents of the surrounding communities, the risk of death or cardiovascular event was not elevated among Walkerton participants with severe or mild gastroenteritis (hazard ratio [HR] for severe gastroenteritis 0.74, 95% confidence interval [CI] 0.38-1.43, mild gastroenteritis HR 0.64, 95% CI 0.42-0.98). Compared with Walkerton participants who had no gastroenteritis, risk of death or cardiovascular event was not elevated among participants with severe or mild gastroenteritis. INTERPRETATION: There was no increase in the risk of cardiovascular disease in the decade following acute infection during a major E. coli O157:H7 outbreak.

Attitudes to sharing personal health information in living kidney donation.

BACKGROUND AND OBJECTIVES: In living kidney donation, transplant professionals consider the rights of a living kidney donor and recipient to keep their personal health information confidential and the need to disclose this information to the other for informed consent. In incompatible kidney exchange, personal health information from multiple living donors and recipients may affect decision making and outcomes. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a survey to understand and compare the preferences of potential donors (n = 43), potential recipients (n = 73), and health professionals (n = 41) toward sharing personal health information (in total 157 individuals). RESULTS: When considering traditional live-donor transplantation, donors and recipients generally agreed that a recipient's health information should be shared with the donor (86 and 80%, respectively) and that a donor's information should be shared with the recipient (97 and 89%, respectively). When considering incompatible kidney exchange, donors and recipients generally agreed that a recipient's information should be shared with all donors and recipients involved in the transplant (85 and 85%, respectively) and that a donor's information should also be shared with all involved (95 and 90%, respectively). These results were contrary to attitudes expressed by transplant professionals, who frequently disagreed about whether such information should be shared. CONCLUSIONS: Future policies and practice could facilitate greater sharing of personal health information in living kidney donation. This requires a consideration of which information is relevant, how to put it in context, and a plan to obtain consent from all concerned.

Discovering misattributed paternity in living kidney donation: prevalence, preference, and practice.

When evaluating a living kidney donor and recipient with a father-child relationship, it may be discovered that the two are not biologically related. We analyzed data from the United Network for Organ Sharing and the Canadian Organ Replacement Registry to determine how frequently this occurs. We surveyed 102 potential donors, recipients, and transplant professionals for their opinion on whether such information should be disclosed to the donor-recipient pair. We communicated with transplant professionals from 13 Canadian centers on current practices for handling this information. In the United States and Canada, the prevalence of father-child living kidney donor-recipient pairs with less than a one-haplotype human leukocyte antigen match (i.e., misattributed paternity) is between 1% and 3%, or approximately 0.25% to 0.5% of all living kidney donations. Opinions about revealing this information were variable: 23% strongly favored disclosure; whereas, 24% were strongly opposed to it. Current practices are variable; some centers disclose this information, whereas others do not. Discovering misattributed paternity in living donation is uncommon but can occur. Opinions on how to deal with this sensitive information are variable. Discussion among transplant professionals will facilitate best practices and policies. Strategies adopted by some centers can be considered.
