110509 MEDICAL DECISIONS: AUTONOMY and INFORMED CONSENT
Background reading material for Year 4 Semester 2 Medical Students at the Faculty of
Medicine King Fahad Medical City Riyadh 09th
May 2011 by Professor Omar Hasan
Kasule Sr.
1.0 CAPACITY (COMPETENCE) TO GIVE CONSENT
Informed consent is given only by a person who is capacitous (competent). The following
are criteria (tests of capacity) are used to judge whether the patient is capacitous: (a)
Understands what the procedure is. (b) Understands the reason for the procedure. (c)
Understand the benefits and risks of the procedure. (d) Has the ability of judging and
weighing the information before coming to a decision (e) Has sufficient memory to retain
information given for a long enough period to enable effective decision making (f)
Understands the consequences of refusing treatment
2.0 THE RIGHT OF AUTONOMY
The patient has the right of autonomy which is control of what is done to his/her body.
Autonomy is a basic human right that cannot be violated except in exceptional
circumstances explained below. No medical examination or medical procedures can be
carried out without informed consent of the patient except in cases of legal incompetence.
The patient has the purest intentions in decisions in the best interests of his or her life.
Others may have bias their decision-making.
3.0 CONSENT FOR COMPETENT ADULTS
Consent can be explicit (oral, written, or non-verbal) or implied. For example a patient
undressing for examination implies consent but often this is not enough we need to ask
specifically for informed consent as explained below.
The patient must be free and capable of giving informed consent. Pressure on the patient
by the family or the healthcare workers invalidates consent. Informed consent requires
disclosure by the physician, understanding by the patient, voluntariness of the decision,
legal competence of the patient (also called capacity), disclosure of all treatment
alternatives and recommendation of the physician on the best course of action, decision
by the patient, and authorization by the patient to carry out the procedures. Consent
should be properly documented.
The patient is free to make decisions regarding choice of physicians and choice of
treatments. Consent is limited to what was explained to the patient except in an
emergency. The scope of consent is limited to what the patient agreed to and the
procedures cannot exceed that except in emergencies. Consent also has a time limitation.
If a long time elapses between consent and the procedure it is better to obtain new
consent.
The patient is free to withdraw consent at a later time and this decision must be respected.
Refusal of treatment is a human right that must be respected. Refusal to consent must be
an informed refusal (patient understands what he is doing). Refusal of treatment should
be documented properly. Refusal to consent by a competent adult even if irrational is

conclusive and treatment can only be given by permission of the court. A patient who
refuses a treatment has no automatic right to demand an alternative and may be more
expensive procedure.
Doubts about whether consent was or was not given consent are resolved in favor of
preserving life.
In some legal systems spouses and family members do not have an automatic right to
consent and a spouse cannot overrule the patientâs choice.
Informed consent is still required for physicians in special practices such as a shipâs
doctor, prison doctor, and doctors in armed forces. Police surgeons may have to carry out
examinations on suspects without informed consent.
Physician assisted suicide, active euthanasia, and voluntary euthanasia are illegal even if
done with the consent of the patient.
2.0 CONSENT FOR INCOMPETENT ADULTS
Three tools are used for consent in cases of incompetent adults who are unconscious
regarding starting, withholding, or withdrawal of treatment: a do not resuscitate order
(DNR), advance directives and proxy informed consent by the family or any other person
with the power of attorney. In some legal systems the family does not automatically have
the right to decide unless authorized beforehand. In some cases courts may be asked to
intervene and solve the controversy.
A do not resuscitate order (DNR) by a physician could create legal complications and
must be used with care.
Consent can be by proxy in the form of the patient delegating decision making or by
means of a living will. The living will has the following advantages: (a) reassuring the
patient that terminal care will be carried out as he or she desires (b) providing guidance
and legal protection and thus relieving the physicians of the burden of decision making
and legal liabilities (c) relieving the family of the mental stress involved in making
decisions about terminal care. The disadvantage of a living will is that it may not
anticipate all developments of the future thus limiting the options available to the
physicians and the family.
The device of the power of attorney can be used instead of the living will or advance
directive. Decision by a proxy can work in two ways: (a) decide what the patient would
have decided if able (b) decide in the best interests of the patient.
In general in cases of incompetence and in the absence of an alternative decision
mechanism the physician in charge does what he thinks is in the best interests of the
patient. This is particularly relevant in cases of emergencies.
3.0 CONSENT IN SPECIAL CASES

Mental patients cannot consent to treatment, research, or sterilization because of their
intellectual incompetence. They are admitted, detained, and treated voluntarily or
involuntarily for their own benefit, in emergencies, for purposes of assessment, if they are
a danger to themselves, or on a court order. In this case treatment is compulsory.
Nutrition, hydration, and treatment can be withdrawn in a persistent vegetative state since
the chance of recovery is low. There is no moral difference between withholding and
withdrawing futile treatment.
Labor and delivery are emergencies that require immediate decisions but the woman may
not be competent and proxies are used. Forced medical intervention and cesarean section
may be ordered in the fetal interest. Birth plans can be treated as an advance directive.
Suicidal patients tend to refuse treatment because they want to die.
4.0 CONSENT FOR CHILDREN
In general parents or persons with parental responsibilities make decisions for children.
Competent children can consent to treatment but cannot refuse treatment. The consent of
one parent is sufficient if the 2 disagree. Parental choice takes precedence over the childâs
choice. Courts can overrule parents. Life-saving treatment of minors is given even if
parents refuse. Parental choice is final in therapeutic or non-therapeutic research on
children.
