National Plan for the Management of Shortages of Labile Blood Components

This phase includes a range of inventory levels ranging from an ideal inventory to shortages that occur periodically.

The national blood inventory is not sufficient to continue with routine transfusion practices.

The blood inventory levels are insufficient to ensure that patients with non-elective indications for transfusion will receive the required transfusion.

Who Shall Receive the Blood during a Critical Shortage?

55 year old male ex-smoker with multiple

trauma

Neonate undergoing urgent cardiac

transplantation

75 year old politician with multiple

medical problems responsible for

reforming health care with a ruptured

aortic aneurysm

Objectives

To understand the conflict between ethical

decisions and resource allocation

To describe the ethical principles of making

decisions about resource allocation

To describe potential methods of incorporating

ethical decisions into resource allocation

Ethics

Page 13: Nadine Shehata MD, MSc University of Toronto, St. Michael’s Hospital, Canadian Blood Services

Ethical Principles Are to Guide Decisions

Page 14: Nadine Shehata MD, MSc University of Toronto, St. Michael’s Hospital, Canadian Blood Services

Four Precepts for Respect

1. Autonomy 2. Beneficence

3. Nonmaleficence 4. JusticeDistributive justice

Page 15: Nadine Shehata MD, MSc University of Toronto, St. Michael’s Hospital, Canadian Blood Services

Shortages Create Conflicts in Ethical Principles Personal autonomy Beneficence

The duty of society is to preserve those values that contribute to the common good of society

Nonmaleficence The importance of protecting the most

vulnerable from exploitation by those with power and influence

Justice The ethical obligations of third parties i.e.,

health professions

A Guide to Making Ethical Decisions

1. Rational

2. Redeeming

3. Respectful

Four Categories of Ethical Values for Resource Allocation

1. Treating people equally

2. Favoring the worst-off: prioritarianism

3. Maximizing total benefits: utilitarianism

4. Promoting and rewarding social usefulness

The Combination of Ethical Principles Ethical principles can be combined

To allow for the incorporation of the intricacy of moral values

To allow for the justification of choices about inclusion, balancing and specification

Disadvantages Increases the overall complexity There may be disagreement about

which principles to include

Summary and Conclusion

Scarce resources create a conflict of ethical decisions

There are several ethical principles that can be used to guide decisions about resource allocation during periods of critical blood shortages

An allocation system should make clear that all individuals are worth saving, and that no ethical principle to guide resource allocation is sufficient on its own

White DB et al. Annals of Internal Medicine 2009 Jan 20; 150(2): 132-8. Persad G et al. Lancet 2009 Jan 31; 373(9661): 423-31.

Page 29: Nadine Shehata MD, MSc University of Toronto, St. Michael’s Hospital, Canadian Blood Services

Summary and Conclusion

A multi-principle strategy has the

potential to decrease the conflict of

how to allocate resources

It is the responsibility of everyone to

discriminate wherever necessary to

ensure that our limited resources go

where they will do the most good

Page 30: Nadine Shehata MD, MSc University of Toronto, St. Michael’s Hospital, Canadian Blood Services

Summary and Conclusion

Prepare for the worse case

Have a triage criteria that is ethical,

defensible and fair to all

Maintain human dignity of all patients
