A 68-year-old man is being evaluated in your radiation oncology clinic for treatment of a solid tumor. Your hospital has just purchased a new proton beam purported to deliver targeted radiation with fewer side effects than traditional radiation therapy. The patient expresses strong interest in receiving proton beam therapy, and you feel that he may have a better outcome with this new treatment modality. Later that day, an executive from the patient's insurance company calls to tell you that proton beam therapy will cost the company (but not the patient) a much larger amount of money than traditional therapy. They are willing to pay for proton beam therapy, but request that you convince the patient to undergo traditional therapy instead. You have a longstanding relationship with this insurance company as well as this particular executive. How should you proceed?

Proceed with proton beam therapy as discussed at your patient's appointment

Tell the patient that proton beam therapy will not be covered by his insurance company, so you will need to proceed with traditional radiation therapy

Discuss the issue of cost to the insurer with your patient, relaying the company's request to him without making further commentary or recommendation

Call your hospital's ethics committee for a formal consultation

Discuss the issue of cost to the insurer with your patient, pointing out that keeping his insurance company happy may make them more likely to cover additional treatments in the future

A 52-year-old man with stage IV melanoma comes to the physician with his wife for a routine follow-up examination. He was recently diagnosed with new bone and brain metastases despite receiving aggressive chemotherapy but has not disclosed this to his wife. He has given verbal consent to discuss his prognosis with his wife and asks the doctor to inform her of his condition because he does not wish to do so himself. She is tearful and has many questions about his condition. Which of the following would be the most appropriate statement by the physician to begin the interview with the patient's wife?

What is your understanding of your husband's current condition?

Have you discussed a living will or goals of care together?

We should talk about how we can manage his symptoms with additional chemotherapy.

Why do you think your husband has not discussed his medical condition with you?

Your husband has end-stage cancer, and his prognosis is poor.

A 19-year-old man presents to an orthopedic surgeon to discuss repair of his torn anterior cruciate ligament. He suffered the injury during a college basketball game 1 week ago and has been using a knee immobilizer since the accident.

A 28-year-old woman dies shortly after receiving a blood transfusion. Autopsy reveals widespread intravascular hemolysis and acute renal failure. Investigation reveals that she received type A blood, but her medical record indicates she was type O. In a malpractice lawsuit, which of the following elements must be proven?

Duty, breach, causation, and damages

A healthy, 16-year-old girl is brought in by her mother for a wellness visit. During the appointment, the patient’s mother brings up concerns about her daughter’s acne. The patient has had acne for 2 years. She washes her face twice a day with benzoyl peroxide and has been on doxycycline for 2 months with only mild improvement. The patient does not feel that the acne is related to her menstrual cycles. The patient’s mother states she does well in school and is the captain of the junior varsity cross-country team. She is worried that the acne is starting to affect her daughter’s self-esteem. The patient states that prom is coming up, and she is considering not going because she hates taking pictures. Upon physical exam, there are multiple open and closed comedones and scattered, red nodules on the patient’s face with evidence of scarring. The patient’s mother says her neighbor’s son tried isotretinoin and wants to know if that may work for her daughter. While talking about the risk factors for isotretinoin, you mention that patient will need to be on 2 forms of birth control. The mother asks, “Is that really necessary? We are a very religious family and my daughter knows our household rule about no sex before marriage.” Which of the following is the next step in management?

Ask the mother to leave the room before talking to the patient about her sexual activity

Have the patient take a pregnancy test to prove abstinence

Talk to patient and mother about patient’s sexual activity, since parental permission is needed for isotretinoin

Prescribe the isotretinoin as the patient does not need additional contraception if she is abstinent

Prescribe the isotretinoin after giving the patient a handout about birth control methods

A 26-year-old man comes to the emergency department because of a 1-week history of fever, throat pain, and difficulty swallowing. Head and neck examination shows an erythematous pharynx with purulent exudates overlying the palatine tonsils. Microscopic examination of a throat culture shows pink, spherical bacteria arranged in chains. Treatment with amoxicillin is initiated. A day later, a physician colleague from another department approaches the physician in the lobby of the hospital and asks about this patient, saying, "Did you see him? What does he have? He's someone I play football with and he hasn't come to play for the past 5 days. I'm worried about him." Which of the following is the most appropriate action by the physician?

Inform the colleague that they cannot divulge any information about the patient

Inform the colleague that they should ask the patient's attending physician

Tell the colleague the patient's case file number so they can look it up themselves

Tell the colleague that they cannot tell them the diagnosis but that their friend was treated with antibiotics

Ask the colleague to meet in the office so they can discuss the patient in private

Research ethics principles for USMLE Step 3: High-Yield Behavioral Science Lessons

Core Principles - The Belmont Trio

Established by the Belmont Report, this framework guides US human research ethics.

Respect for Persons: Treat individuals as autonomous agents.
- Requires robust informed consent: full disclosure, comprehension, and voluntary participation.
- Mandates special protections for those with diminished autonomy (e.g., children, prisoners, cognitively impaired).
Beneficence: An obligation to "do no harm" (non-maleficence) and to maximize benefits while minimizing risks.
Justice: Fair distribution of the burdens and benefits of research.
- Demands equitable selection of subjects, preventing exploitation of vulnerable groups.

⭐ Vulnerable populations (e.g., children, prisoners, pregnant women) lack full autonomy and require additional protections to prevent coercion or undue influence.

Belmont Report: Informed Consent Principles & Applications

Core Principle: An ongoing, voluntary dialogue ensuring participants understand a study's purpose, procedures, potential risks, benefits, and alternatives before agreeing. It is a process, not a single event.
Pillars of Valid Consent:
- Disclosure: Imparting all relevant information. 📌 Mnemonic: BRAIN (Benefits, Risks, Alternatives, Indications, Nature of procedure).
- Understanding: Ensuring the participant comprehends the information; requires clear, jargon-free language.
- Capacity: The individual's ability to make an autonomous, rational decision.
- Voluntariness: Freedom from coercion or undue influence.
Exceptions in Research:
- Waiver of consent is possible for minimal-risk research via IRB approval.
- Emergency research has strict, narrow exceptions.

⭐ For minors, obtain informed consent from parents/guardians and assent (affirmative agreement) from the child, typically if aged >7 years.

Institutional Review Board - The Ethics Police

Formal committee that approves, monitors, and reviews biomedical and behavioral research involving humans.
Primary mandate: Protect the rights, safety, and welfare of human research subjects.
Composition: Minimum 5 members with diverse backgrounds (scientific, non-scientific, and community members).
Reviews protocols for ethical concerns, risk-benefit analysis, and informed consent procedures.

⭐ To ensure a balanced perspective, the IRB must include at least one non-scientist and one member unaffiliated with the institution.

Vulnerable Subjects - Handle With Care

Require extra protections against coercion or undue influence; the IRB must implement additional safeguards.
Key populations include:
- Children & minors
- Prisoners
- Pregnant women, fetuses, and neonates
- Cognitively impaired or educationally/economically disadvantaged individuals
📌 For children, obtain parental/guardian permission AND the child's own assent (agreement), if they are capable (e.g., age >7).
For prisoners, incentives must not be coercive (e.g., suggesting parole).

⭐ For research involving children, both parental permission and child assent are ethically required. Assent is the child's affirmative agreement, not just a failure to object.

High‑Yield Points - ⚡ Biggest Takeaways

Informed consent is mandatory; subjects must be competent and understand the study.

Beneficence (do good) and non-maleficence (do no harm) are paramount.

Justice requires fair selection of subjects, avoiding exploitation of vulnerable populations.

Autonomy respects a patient's right to make their own decisions about participation.

All research requires Institutional Review Board (IRB) approval to protect human subjects.

Confidentiality of patient data must be maintained throughout the study.
