Principles of Medical Bioethics
Medical practitioners should act in the best interests of the patient.
The Principle of Beneficence
Medical practitioners must not harm the patient.
The Principle of Non-Maleficence
Capable persons must be allowed to accept or refuse recommended medical interventions.
The Principle of Respect for Autonomy
Patients, their families, and surrogate decision makers, as well as their health care providers, all have the right to dignity.
The Principle of Respect for Dignity
The capable patient must be provided with the complete truth about her/his medical condition.
The Principle of Respect for Veracity
Health care resources should be distributed in a fair way among the members of society.
The Principle of Distributive Justice
Proposed approach of evidence-based medical ethics
Based on the tenets of evidence-based medicine (EBM), which: Aims to apply the best available evidence (gained from
rigorous application of the scientific method) to clinical decision making
Seeks to assess the strength of evidence of the risks and benefits of treatments (including lack of treatment) and diagnostic tests
Helps clinicians to learn whether or not any treatment will do more good than harm
Evidence-Based Medical Ethics
Evidence-Based Medical Ethics: Aims to apply the best available “evidence” gained from
EBM, widely accepted ethical principles, and legal precedent
Incorporates aspects of cultural competency and an evolving medical knowledge set/technology (we can/but should we?), and an evolving set of laws
Helps clinicians guide patients to make “good decisions” for themselves, particularly when options have potential to do both good and harm
Emphasizes that “right” and “wrong” decisions are personal choices of the patient and are acceptable if they are well-informed (it’s not about you)
Evidence-Based Medical Ethics
Some of the most difficult medical decisions are made when the patient themselves is unable to make them Includes how a patient’s life will end
Natural Death Act, 1976 (California) First time a state allowed citizens to make
their choices for end-of-life care known in advance
Physicians honoring this “directive” cannot be charged with criminal liability or unprofessional conduct
Led to development of the “Living Will” Later led to the “Power of Attorney for Health
Care” These two documents collectively make up
Advance Directives
Advance Directives
Legally executed document by a capable patient
Authorizes physicians to withhold or withdraw life-sustaining medical treatment when the patient, in the future, lacks the capacity to make health care decisions
In some states requires a “terminal condition”, but in others includes states like PVS
Can include decisions on “artificial nutrition and hydration”
Living Will
Legal document a capable patient uses to appoint a “health care agent” (HCA) Aka “representative”, “proxy”,
“surrogate” Rules vary greatly from state to state
That person will make decisions for the patient when they are no longer capable Includes employing/discharging providers Includes consent to admit/discharge from
facilities Includes ability to give, withdraw, or
withhold consent for diagnostic and therapeutic procedures
(Durable) Power of Attorney for Health Care
A patient’s wishes for end-of-life care, in particular, should be discussed in advance with the HCA… but often are not When not, often result in conflicts
between family members Sometimes wishes are discussed but not
legally documented When a patient’s wishes are not
documented, the HCA should act using one of two principles: “Substituted judgment” “Best interests standard”
(Durable) Power of Attorney for Health Care
Come into play when there are no ADs Laws vary to some degree by state with respect to “priority” status
of an individual to be a HCA on behalf of the patient Laws also vary state to state by what determines a “marriage” or
“family”
Surrogate Decision Makers

John Doe, 50 year old AAM, found unresponsive in an alleyway by passersby Covered with blood
and dirt ? Homeless No identifying information Weak pulse, shallow
respirations
Case 1: When a Patient is Unidentifiable
In the field: Placed on a backboard, intubated,
and a hard cervical collar placed In the ED:
Fractures to the pelvis and bilateral femurs
Splenic and liver lacerations Collapsed left lung Large intracranial hemorrhage
(subdural hematoma) Police involved, fingerprinting
unrevealing
Case 1: When a Patient is Unidentifiable
Place/keep on a ventilator ?
Insert a PEG tube for nutrition?
Place an IV? A “central line”?
Transfuse blood? Take to the OR?
What do you do next?
How much do you do to help this patient?
How long do you wait before moving forward?
When do you stop efforts/where do you draw the line?
What do you do next?
In patients with CNS injuries, mechanical ventilation may be necessary to support life
Prolonged need for ventilation and placement of a tracheostomy may be observed
The goal of any patient on a ventilator is weaning
Study of 100 patients by Namen, et al.: GCS < 8: 33% success rate of
extubation GCS > 8: 75% success rate

Canterbury V. Spence [1972] 464 F 2d 772, U.S. Court of
Appeals, District of Columbia Circuit Legally-recognized exceptions to
Informed Consent:“… when a patient is unconscious or otherwise incapable of consenting, and harm from a failure to treat is imminent and outweighs any harm threatened by the proposed treatment”
The Law
The Principle of Beneficence The Principle of Non-Maleficence The Principle of Respect for
Autonomy The Principle of Respect for Dignity The Principle of Respect for Veracity The Principle of Distributive Justice
The Ethics
The Principle of Beneficence Injuries have been initially treated Immediate death has been prevented Life sustained until chances for recovery could be determined Pain was treated
The Principle of Non-Maleficence The Principle of Respect for Autonomy The Principle of Respect for Dignity The Principle of Respect for Veracity The Principle of Distributive Justice
The Ethics
The Principle of Beneficence The Principle of Non-Maleficence
Risks of interventions to date were weighed against benefits Further plan is being considered carefully with respect to this
principle Must consider a “line” to draw re: possible futility of efforts
The Principle of Respect for Autonomy The Principle of Respect for Dignity The Principle of Respect for Veracity The Principle of Distributive Justice
The Ethics
The Principle of Beneficence The Principle of Non-Maleficence The Principle of Respect for Autonomy
Does not apply here Patient cannot be identified Family cannot be contacted No “substituted judgment” can be made A legal guardian must be sought Must use “best interests standard” based on above two principles
▪ Take likelihood for recovery/improvement and contrast with pain/suffering and QOL may attain
▪ Will reasonable goals be met or will the end of life be artificially postponed? Are there aspects of culture that should be considered here?
The Principle of Respect for Dignity The Principle of Respect for Veracity The Principle of Distributive Justice
The Ethics
The Principle of Beneficence The Principle of Non-Maleficence The Principle of Respect for Autonomy The Principle of Respect for Dignity
Important as the patient is vulnerable and has no “voice” Must protect privacy and bodily integrity to greatest extent
possible Invasive life-sustaining measures should not be initiated
simply because the patient’s own wishes cannot be known The Principle of Respect for Veracity The Principle of Distributive Justice
The Ethics
The Principle of Beneficence The Principle of Non-Maleficence The Principle of Respect for Autonomy The Principle of Respect for Dignity The Principle of Respect for Veracity
The legal guardian must receive all possible and relevant information
Information must be presented clearly and without bias/leading
The Principle of Distributive Justice

Does not apply here Resources are not limited in this case*** Decisions to withdraw or withhold medical treatment
cannot be made because: ▪ Patient cannot be identified▪ Patient’s “societal value”

Represented on the PHLS Public Health Code of Ethics Committee are public health professionals from: Local and state public health Academia The Centers for Disease Control
and Prevention (CDC) The American Public Health
Association (APHA) Guide is published on the APHA
website Has 12 guiding principles Has a different perspective
than medical bioethics
Public Health Ethics
1. Public health should address principally the fundamental causes of disease and requirements for health, aiming to prevent adverse health outcomes.
2. Public health should achieve community health in a way that respects the rights of individuals in the community.
3. Public health policies, programs, and priorities should be developed and evaluated through processes that ensure an opportunity for input from community members.
4. Public health should advocate and work for the empowerment of disenfranchised community members, aiming to ensure that the basic resources and conditions necessary for health are accessible to all.
5. Public health should seek the information needed to implement effective policies and programs that protect and promote health.
6. Public health institutions should provide communities with the information they have that is needed for decisions on policies or programs and should obtain the community’s consent for their implementation.
Public Health Ethics
7. Public health institutions should act in a timely manner on the information they have within the resources and the mandate given to them by the public.
8. Public health programs and policies should incorporate a variety of approaches that anticipate and respect diverse values, beliefs, and cultures in the community.
9. Public health programs and policies should be implemented in a manner that most enhances the physical and social environment.
10. Public health institutions should protect the confidentiality of information that can bring harm to an individual or community if made public. Exceptions must be justified on the basis of the high likelihood of significant harm to the individual or others.
11. Public health institutions should ensure the professional competence of their employees.
12. Public health institutions and their employees should engage in collaborations and affiliations in ways that build the public’s trust and the institution’s effectiveness.
Public Health Ethics
Principles offer guidance but not answers
Principles should be considered when working on public health initiatives
Principles often need to be thought of in light of medical bioethics
Who “polices” this?
Public Health Ethics
Please stop talking Dad!
José M., 34 year old Latino male in NC Known HIV infection x5 years, not on
ART Had not seen an MD x2 years as is
uninsured Last known CD4+ count was 201/μL 2 months of cough, malaise, fevers,
15# weight loss Progressive shortness of breath,
weakness Encouraged to come in by partner of
4 years, Justin (HIV neg.)
Case 2: When a Partner is Excluded
In the ED: Fever High heart and respiratory rates Low oxygen saturation Chest x-ray suggestive of diffuse
pneumonia in both lungs Sputum examination indicates
presence of Pneumocystis jirovecii
CD4+ count reported now as 12/μL
Case 2: When a Partner is Excluded
Hospital course: Symptoms worsened Transferred to the ICU Developed acute respiratory
distress syndrome (ARDS) and progressive multi-system organ failure (MSOF)
Sedated and placed on mechanical ventilation
Had not completed a Living Will or HCPOA paperwork previously
Case 2: When a Partner is Excluded
Hospital course: José’s parents notified Although he had been in
close contact with his parents, José had never disclosed his S.O. or HIV status to them
Had never introduced them to Justin out of concern they would not be accepting
Case 2: When a Partner is Excluded
Hospital course: José’s father asks
“does my son have AIDS?”
José’s mother says “that man” (Justin) should not be allowed into the ICU room any more
Case 2: When a Partner is Excluded
How much information do you disclose to José’s family?
What decisions do they need to make now? What decisions might they need to make
soon? What rights does Justin have? Should José’s parents be told that Justin is
HIV negative? Can José’s parents make “good” medical
decisions for him? What cultural aspects are important in this
case? How does one best balance the principles of
beneficence, autonomy, non-maleficence, veracity, and dignity in this case?
What do you do next?
