Part B: The Clinical Relationship: Consent, Autonomy, and Confidentiality
An Introduction to Bioethics.
Mrs. R is 61, in for fatigue and weight loss. The colonoscopy found colon cancer — serious, but treatable. She is frightened, and her daughter Dana does most of the talking. Mrs. R asks: “So what happens now?”
Four residents tell you how they would answer her:
Read the four aloud, in four different voices. The facts never change across them; only what the clinician does with authority changes.
By the end of Part B, you will be able to:

Autonomy versus Beneficence
Ezekiel and Linda Emanuel mapped the clinician–patient relationship into four models in a 1992 JAMA paper that is still the standard reference (Emanuel and Emanuel 1992):
| Model | Which resident | Main clinician role | Main risk |
|---|---|---|---|
| Paternalistic | 3 | Decide what is best | Patient becomes passive |
| Informative | 1 | Provide facts and options | Clinician becomes a vending machine |
| Interpretive | 4 | Help clarify the patient’s values | Clinician may over-read the patient |
| Deliberative | 2 | Recommend and reason about values | Persuasion can slide into pressure |
Match a model to each case — and say why:
And: should Mrs. R get the same model at every visit?
Now Mrs. R arrives having read everything online, convinced by an ad and an AI chatbot that she needs one specific drug. Does the informative model still work when a patient cannot judge her own information?
Note
“Every human being of adult years and sound mind has a right to determine what shall be done with his own body; and a surgeon who performs an operation without his patient’s consent commits an assault.”
Justice Benjamin Cardozo, Schloendorff v. Society of New York Hospital (1914) (New York Court of Appeals 1914)
The term “informed consent” was not coined until Salgo (1957). The modern standard for how much to disclose was set in Canterbury v. Spence (1972).
| Standard | The test it uses | The problem it has |
|---|---|---|
| “Reasonable physician” (older) | Disclose what a typical doctor would disclose | Lets the profession set its own bar |
| “Reasonable patient” (Canterbury, 1972) | Disclose what a reasonable patient would consider material to the decision | Whose “reasonable patient”? |
| Subjective / this patient (emerging) | Disclose what this patient would find material | Hard to prove, but closest to real autonomy |
Most U.S. jurisdictions now use some version of the Canterbury “reasonable patient” rule — disclosure is measured from the patient’s side of the table, not the doctor’s.
| Element | The practical question |
|---|---|
| Disclosure | Was the relevant information provided? |
| Understanding | Does the patient actually grasp it? |
| Voluntariness | Is the choice free from controlling pressure? |
| Capacity | Can the patient make this decision now? |
The standard clinical test, Appelbaum and Grisso’s four abilities, asks whether the patient can (Appelbaum 2007):
Failing only the last two — appreciation and reasoning — is what usually distinguishes incapacity from a merely unusual choice.
This is the chapter’s paired case study. You don’t need the full facts yet — only enough to feel the autonomy/beneficence collision before you read it properly.
A competent adult refuses a blood transfusion that would almost certainly save their life.

You may disclose when
You must disclose
| Tarasoff I (1974) | Tarasoff II (1976) | |
|---|---|---|
| Duty | Duty to warn the victim | Duty to protect the victim |
| Options | Tell the identifiable target | Warn, notify police, hospitalize — whatever a reasonable clinician would do |
| Trigger | A serious threat to an identifiable person | Same — but the response is broader and clinically judged |
| Today | Some states still use a narrow “warn” rule | Many adopted “protect”; some make it permissive, a few reject it entirely |
There is no single national Tarasoff rule. There is a default ethical question — serious, specific danger to an identifiable person — that each state answers differently.
“We conclude that the public policy favoring protection of the confidential character of patient-psychotherapist communications must yield to the extent to which disclosure is essential to avert danger to others. The protective privilege ends where the public peril begins.”
Tarasoff v. Regents of the University of California (1976) (Supreme Court of California 1976)
You are a nursing student on a med-surg unit. Your old roommate is admitted two doors down — and you have chart access.
You’re genuinely worried about her. You open her chart “just to see if she’s okay.” You tell no one. No one is harmed.
Start with the roommate’s chart, then turn the privacy default on its head:
Note
The biopsy is worse than expected. Before you go in, Dana stops you in the hallway:
“In our family, we don’t tell elders news like this. It will crush her. Please talk to me, not her.”
The team wants to respect the family’s culture. The team also wants to respect Mrs. R.
Note
Part A explained why modern medicine rejects unchecked paternalism. Part B asked what replaces it: guided, transparent, autonomy-respecting care. Following Mrs. R, we saw the four clinician–patient models, the four elements of valid consent and the case law (Schloendorff → Canterbury) behind them, the difference between an unwise choice and an incapacitated one, and confidentiality and truth-telling as defaults with disciplined, evolving exceptions — from Tarasoff to open notes. Through all of it you chose a model with Mrs. R rather than for her, and asked her, not Dana, how she wanted the truth handled.
Write a brief answer to each, or use them as discussion prompts.
Recall
What are the four elements of valid informed consent, and why is a signature by itself not enough?
Apply
A patient with kidney failure clearly explains the risks of refusing dialysis, but her son insists that no “reasonable” mother would refuse treatment and asks the team to override her. How should the team assess capacity and respond to the son’s demand?
Debate
Should patients usually get near-immediate electronic access to clinicians’ notes, test interpretations, and differential diagnoses, even when that may increase anxiety, misunderstanding, or conflict?
