Downward delegation of implantable cardioverter defibrillator decision-making in a restricted-resource environment: the pitfalls of bedside rationing.

Implantable cardioverter defibrillators have been shown to reduce all-cause mortality in some patient populations at risk of sudden death. New Canadian guidelines recommend implantable cardioverter defibrillator therapy for these patients. However, the need for these devices exceeds the funded volumes in many Canadian jurisdictions. As a result, rationing of this resource has been necessary. While rationing at the macro (Ministry of Health) and meso (hospital) levels has achieved some level of acceptance by society, the responsibility for the decisions taken at the micro (individual) patient level actually rests with the physician at the bedside. This 'bedside rationing' creates a moral dilemma for physicians, who are torn between their traditional fiduciary role as 'patient advocate' and the competing role of 'gatekeeper'. This 'downward delegation' of rationing decision-making obscures the reality that rationing occurs, and encourages covert, opaque and inconsistent approaches. The remedy is the development of fair, legitimate procedures for making rationing decisions that include guidelines that structure and constrain those decisions. Macro- and meso-level stakeholders must also recognize and take responsibility for their part in restricting resources in a broadly inclusive and transparent process.

Canadian Cardiovascular Society/Canadian Heart Rhythm Society position paper on implantable cardioverter defibrillator use in Canada.

The Canadian Heart Rhythm Society in conjunction with the Canadian Cardiovascular Society is committed to the promotion of evidence-based practice in Canada. Since the last Canadian guidelines on the management of sudden cardiac death were published in 2000, several well-conducted clinical trials evaluating the implantable cardioverter defibrillator have been completed and published. The Canadian Cardiovascular Society Council has granted permission to review and update guidelines for the indications for implantable cardioverter defibrillators. Furthermore, data are emerging on the potential benefits of biventricular pacing therapy (cardiac resynchronization) for heart failure; recommendations for the use of this therapy have been included in the present paper. Ethical considerations and the economic implications of these recommendations are also included. Canada's heart rhythm specialists, represented by the Canadian Heart Rhythm Society, have been joined by two heart failure specialists, a medical ethicist and an economist, to develop the present position paper. Members of the Canadian Heart Rhythm Society participated in the discussion of these recommendations in open forum meetings and by electronic communication.

Mandatory physician reporting of drivers with cardiac disease: ethical and practical considerations.

Many jurisdictions in Canada have enacted legislation that requires physicians to report their patients to the Ministry of Transport if they have a medical condition that may put them at increased risk to operate a motor vehicle. The Canadian Cardiovascular Society has published guidelines that are designed to assist physicians and policy-makers in their decision-making. Legislation is designed to protect society, and the guidelines are designed to fulfill that mandate. However, in the present paper, important issues that have not been addressed to date are discussed. What is the efficacy of mandatory reporting legislation? What are the harms done to patients who are restricted from driving? What are the costs of the mandatory reporting system? How can the scientific/technical assessment of risk be reconciled with the social/ethical view of risk assessment? Until these issues are addressed, important questions about the ethics, efficacy and cost of mandatory physician reporting will remain unanswered.

Attitudes regarding organ donation from non-heart-beating donors.

PURPOSE: To determine the attitudes toward organ donation from non-heart-beating cadaver donors in a sample of the general public and health care workers. MATERIALS AND METHODS: A moderator-administered questionnaire was completed by members of the general public, recruited randomly from a professional consumer research group's database, and health care workers recruited from the same database, family practice clinics, and local hospitals. Two primary scenarios were tested: (1) patient in coma, not going to survive intensive care unit (ICU), and (2) patient lapsing in and out of consciousness, lifetime institutional care. RESULTS: Sixty members of the general public and 68 health care workers completed the questionnaire. The majority of both groups were aware life support could be withdrawn in Scenario 1, however, significantly fewer were aware life support could also be withdrawn in Scenario 2 (83% general public vs 34% general public, P <.001 and 94% health care workers vs 78% health care workers, P =.012). Uncertainty in prognosis was cited as the primary concern. The issue of organ donation was directly linked with withdrawal of life support. The majority of both groups believed that organ donation would be permissible if further life support were deemed to be not in the patient's best interest because of poor short-term prognosis (94% health care workers and 98% general public for Scenario 1 and 87% health care workers and 81% general public for Scenario 2). The greatest difficulty arose in defining futility of care. Expected quality of life, patient's and family's values, opinions, and religious beliefs were felt to be most important in determining decisions regarding futility and withdrawal of life support. Physician beliefs and values were felt to influence decisions more than they should. CONCLUSIONS: Both the general public and health care workers support the use of non-heart-beating cadaver donors once a decision has been made to withdraw life support. However, both groups raised concerns regarding how the decision to withdraw life support is made.

Values in preventive medicine: the hidden agenda.

We know how lifestyle affects health, yet concern for preventing illness by promoting healthy lifestyles remains marginal in medical practice. Effective preventive strategies can raise daunting moral and political problems about the extent to which individual freedoms may be infringed, particularly on paternalistic grounds. Evaluative questions also arise about more specific matters, such as identifying risk and causal factors, determining what level of risk is acceptable, and deciding how compelling the evidence must be to take preventive action.
