Q

Observational studies
Study type: Case-control study

A

Design: Retrospectively compares a group of people with disease to a group without disease.
Measures/Example: Asks, “What happened?” Odds ratio (OR). Control the case in the OR. Patients with COPD had higher odds of a smoking history than those without COPD.

Observational studies

Study type: Cohort study

A

Design: Compares a group with a given exposure or risk factor to a group without such exposure.
Measures/Example: Looks to see if exposure or risk factor is associated with later development of disease. Can be prospective or retrospective. Disease incidence. Relative risk (RR). People who smoke had a higher risk of developing COPD than people who do not. Cohort = relative risk.

Q

Advance directives

A

Instructions given by a patient in anticipation of the need for a medical decision

88
Q

Oral advance directive

A

Incapacitated patient’s prior oral statements commonly used as guide. Problems arise from variance
in interpretation. If patient was informed, directive was specific, patient made a choice, and
decision was repeated over time to multiple people, then the oral directive is more valid

89
Q

Written advance
directive

A

Delineates specific healthcare interventions that patient anticipates accepting or rejecting during
treatment for a critical or life-threatening illness. A living will is an example

90
Q

Medical power of
attorney

A

Patient designates an agent to make medical decisions in the event that the patient loses decisionmaking capacity. Patient may also specify decisions in clinical situations. Can be revoked by
patient if decision-making capacity is intact. More flexible than a living will

91
Q

Do not resuscitate
order

A

DNR order prohibits cardiopulmonary resuscitation (CPR). Patient may still consider other lifesustaining measures (eg, intubation, feeding tube, chemotherapy)

92
Q

Surrogate decisionmaker

A

If a patient loses decision-making capacity and has not prepared an advance directive, individuals
(surrogates) who know the patient must determine what the patient would have done. Priority of
surrogates: spouse Ž adult children Ž parents Ž siblings Ž other relatives

(the spouse ChilPS in)

93
Q

Examples of exceptions to patient confidentiality (many are state specific) include the following
(“The physician’s good judgment SAVED the day”)

A

Patients with Suicidal/homicidal ideation
ƒ Abuse (children, elderly, and/or prisoners)
ƒ Duty to protect—state-specific laws that sometimes allow physician to inform or somehow
protect potential Victim from harm
ƒ Patients with Epilepsy and other impaired automobile drivers
ƒ Reportable Diseases (eg, STIs, hepatitis, food poisoning); physicians may have a duty to warn
public officials, who will then notify people at risk. Dangerous communicable diseases, such as
TB or Ebola, may require involuntary treatment.

94
Q

95
Q

Delivering bad news SPIKES:

A

Setting - Ensure privacy and eliminate distractions.

Perception - Understand the patient’s understanding and expectations.

Invitation - Ask for permission to disclose the news and desired level of detail.

Knowledge - Share information in small pieces without medical jargon.

Emotions - Acknowledge and allow expression of emotions.

Strategy - Discuss treatment options and goals of care, offer an agenda for the next appointment.

96
Q

Gender and sexuality-inclusive history taking:

A

Avoid assumptions and use gender-neutral terms.

Recognize that assigned sex and gender identity may differ.

State your pronouns and ask patients how they would like to be addressed.

Reassure confidentiality and acknowledge sensitivity.

Only bring up gender or sexuality if relevant to the visit.

97
Q

Trauma-informed communication:

A

Screen for behavioral health and assess mood, substance use, and social supports.
Focus on trauma-related symptoms affecting functioning.
Avoid invasive questions about trauma details.
Reassure patients they can end the physical exam if uncomfortable and offer additional support.

98

Motivational Interviewing:

A

A counseling technique to help patients resolve ambivalence about behavior change. Useful for various conditions such as nicotine dependence and obesity.

99
Q

Assessing Readiness for Change: SMART

A

Important for setting physician-suggested goals. Goals should be SMART (Specific, Measurable, Achievable, Relevant, and Time-bound)

100
Q

Communicating with Patients with Disabilities:

A

Use person-first language. Ask patients about their preferred terms. Talk directly to the patient and include caregivers if necessary.

101
Q

Providing Assistance:

A

Ask if assistance is desired instead of assuming incapability. Respect patients’ independence.

102
Q

Speech Difficulties:

A

Provide extra time and ask patients to write down or rephrase their words if necessary. Repeat to ensure understanding.

103
Q

Cognitive Impairment:

A

Use concrete language, ask direct questions, eliminate distractions, and adjust to the patient’s preferred understanding method.

104
Q

Deaf or Hard of Hearing Patients:

A

Ask about their preferred mode of communication. Use light touch or waving to get their attention.

105
Q

Disability Relevance:

A

Do not bring up a disability if not relevant. Perform a complete physical exam regardless of any challenges posed by the disability.

106
Q

Use of Interpreters:

A

Utilize professionally trained medical interpreters for patients with limited English proficiency. Confirm patient preference for family member interpretation.

107
Q

Respectful Communication:

A

Make eye contact, speak directly to the patient, and avoid third-person statements. Allow extra time and ask one question at a time.

108
Q

Patient is not adherent.

A

Identify and assess any barriers that may hinder the patient’s adherence, including financial, logistical, or other obstacles. Do not force or persuade the patient to adhere, nor recommend them to another doctor.

109
Q

Patient desires an unnecessary
procedure

A

Attempt to understand why the patient wants the procedure and address underlying
concerns. Do not refuse to see the patient or refer to another physician. Avoid
performing unnecessary procedures

110
Q

Patient has difficulty taking
medications

A

Determine what factors are involved in the patient’s difficulties. If comprehension or
memory are issues, use techniques such as providing written instructions, using the
teach-back method, or simplifying treatment regimens.

Family members ask for information
about patient’s prognosis

A

Avoid discussing issues with relatives without the patient’s permission.

112
Q

A patient’s family member asks you
not to disclose the results of a test
if the prognosis is poor because
the patient will be “unable to
handle it.”

A

Explore why the family member believes this would be detrimental, including
possible cultural factors. Explain that if the patient would like to know information
concerning care, it will not be withheld. However, if you believe the patient might
seriously harm self or others if informed, you may invoke therapeutic privilege and
withhold the information

113
Q

A 17-year-old is pregnant and
requests an abortion

A

Many states require parental notification or consent for minors for an abortion. Unless
there are specific medical risks associated with pregnancy, a physician should not
sway the patient’s decision for, or against, an elective abortion (regardless of patient’s
age or fetal condition). Discuss options for terminating the pregnancy and refer to
abortion care, if needed.

114
Q

A 15-year-old is pregnant and wants
to raise the child. Her parents
want you to tell her to give the
child up for adoption.

A

The patient retains the right to make decisions regarding her child, even if her parents
disagree. Provide information to the teenager about the practical aspects of caring
for a baby. Discuss options for terminating the pregnancy, if requested. Encourage
discussion between the teenager and her parents to reach the best decision

115
Q

A terminally ill patient requests
physician-assisted dying.

A

The overwhelming majority of states prohibit most forms of physician-assisted dying.
Physicians may, however, prescribe medically appropriate analgesics even if they
potentially shorten the patient’s life.

116
Q

Patient is suicidal

A

Assess the seriousness of the threat. If patient is actively suicidal with a plan, suggest
remaining in the hospital voluntarily; patient may be hospitalized involuntarily if needed

117
Q

Patient states that you are attractive
and asks if you would go on a date.

A

Use a chaperone if necessary. Romantic relationships with patients are never
appropriate. It may be necessary to transition care to another physician

118
Q

A woman who had a mastectomy
says she now feels “ugly.”

A

Find out why the patient feels this way. Do not offer falsely reassuring statements (eg,
“You still look good”).

119
Q

Patient is angry about the long time
spent in the waiting room

A

Acknowledge the patient’s anger, but do not take a patient’s anger personally. Thank
the patient for being patient and apologize for any inconvenience. Stay away from
efforts to explain the delay.

120
Q

Patient is upset with treatment
received from another physician

A

Suggest that the patient speak directly to that physician regarding the concern. If the
problem is with a member of the office staff, tell the patient you will speak to that
person

121
Q

An invasive test is performed on the
wrong patient

A

Regardless of the outcome, a physician is ethically obligated to inform a patient that a
mistake has been made

122
Q

A patient requires a treatment not
covered by insurance.

A

Discuss all treatment options with patients, even if some are not covered by their
insurance companies. Inform patient of financial assistance programs

123
Q

A 7-year-old boy loses a sister to
cancer and now feels responsible.

A

At ages 5–7, children begin to understand that death is permanent, that all life
functions end completely at death, and that everything that is alive eventually
dies. Provide a direct, concrete description of his sister’s death. Avoid clichés and
euphemisms. Reassure the boy that he is not responsible. Identify and normalize fears
and feelings. Encourage play and healthy coping behaviors (eg, remembering her in
his own way).

124
Q

Patient is victim of intimate partner
violence.

A

Ask if patient is safe and help devise an emergency plan if there isn’t one. Educate
patient on intimate partner violence resources. Do not necessarily pressure patient to
leave a partner or disclose the incident to the authorities (unless required by state law).

125
Q

Patient wants to try alternative or
holistic medicine.

A

Explore any underlying reasons with the patient in a supportive, nonjudgmental
manner. Advise the patient of known benefits and risks of treatment, including
adverse effects, contraindications, and medication interactions

126
Q

Physician colleague presents to
work impaired.

A

This presents a potential risk to patient safety. You have an ethical and usually a legal
obligation to report impaired colleagues so they can cease patient care and receive
appropriate assistance in a timely manner. Seek guidance in reporting as procedures
and applicable law vary by institution and state

127
Q

Patient is officially determined to
suffer brain death. Patient’s family
insists on maintaining life support
indefinitely because patient is still
moving when touched.

A

Gently explain to family that there is no chance of recovery, and that brain death is
equivalent to death. Movement is due to spinal arc reflex and is not voluntary. Bring
case to appropriate ethics board regarding futility of care and withdrawal of life
support

128
Q

A pharmaceutical company offers
you a sponsorship in exchange for
advertising its new drug.

A

Reject this offer. Generally, decline gifts and sponsorships to avoid any conflict of
interest. The AMA Code of Ethics does make exceptions for gifts directly benefitting
patients; special funding for medical education of students, residents, fellows; grants
whose recipients are chosen by independent institutional criteria; and funds that are
distributed without attribution to sponsors

129
Q

Patient requests a nonemergent
procedure that is against your
personal or religious beliefs.

A

Provide accurate and unbiased information so patients can make an informed decision.
In a neutral, nonjudgmental manner, explain to the patient that you do not perform
the procedure but offer to refer to another physician.

130
Q

Mother and 15-year-old daughter
are unresponsive following a
car accident and are bleeding
internally. Father says do not
transfuse because they are
Jehovah’s Witnesses.

A

Transfuse daughter, but do not transfuse mother. Emergent care can be refused by the
healthcare proxy for an adult, particularly when patient preferences are known or
reasonably inferred, but not for a minor based solely on faith

131
Q

A dependent patient presents
with injuries inconsistent with
caretaker’s story.

A

Document detailed history and physical. If possible and appropriate, interview the
patient alone. Provide any necessary medical care. If suspicion remains, contact
the appropriate agencies or authorities (eg, child or adult protective services) for an
evaluation. Inform the caretaker of your obligation to report. Physicians are required
by law to report any reasonable suspicion of abuse, neglect, or endangerment.

132
Q

A pediatrician recommends standard
vaccinations for a patient, but the
child’s parent refuses.

A

Address any concerns the parent has. Explain the risks and benefits of vaccinations
and why they are recommended. Do not administer routine vaccinations without the
parent’s consent
