Physician–patient privilege

Physician–patient privilege is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Physician–patient privilege rather than just read about it. In short: Physician–patient privilege is a legal concept, related to medical confidentiality, that protects communications between a patient and their doctor from being used against the patient in court. It is a part of the rules of evidence in many common law jurisdictions.

Key takeaways

Physician–patient privilege belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Physician–patient privilege to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Physician–patient privilege is a legal concept, related to medical confidentiality, that protects communications between a patient and their doctor from being used against the patient in court. It is a part of the rules of evidence in many common law jurisdictions. Almost every jurisdiction that recognizes physician–patient privilege permits a physician not to testify in court about medical information about their patient, either by statute or through case law, and limits the privilege to knowledge acquired during the course of providing medical services. In some jurisdictions, conversations between a patient and physician may be privileged in both criminal and civil courts.

Scope The privilege may cover the situation where a patient confesses to a psychiatrist that they committed a particular crime. It may also cover normal inquiries regarding matters such as injuries that may result in civil action. For example, any defendant that the patient may be suing at the time cannot ask the doctor if the patient ever expressed the belief that their condition had improved. However, the rule generally does not apply to confidences shared with physicians when they are not serving in the role of medical providers. The reasoning behind the rule is that a level of trust must exist in the doctor–patient relationship so that the physician can properly treat the patient. If the patient were fearful of telling the truth to the physician because they believed the physician would report such behavior to the authorities, the treatment process could be rendered far more difficult, or the physician could make an incorrect diagnosis. For example, a below-age of consent patient came to a doctor with a sexually transmitted disease. The doctor is usually required to obtain a list of the patient's sexual contacts to inform them that they need treatment. This is an important health concern. However, the patient may be reluctant to divulge the names of their older sexual partners, for fear that they will be charged with statutory rape. In some jurisdictions, the doctor cannot be forced to reveal the information revealed by their patient to anyone except to particular organizations, as specified by law, and they too are required to keep that information confidential. In the case the police become aware of such information, they are not allowed to use it in court as proof of the sexual misconduct except as provided by express intent of the legislative body and formalized into law. The law in Ontario, Canada, requires that physicians report patients who, in the opinion of the physician, may be unfit to drive for medical reasons as per Section 203 of the Highway Traffic Act. The law in New Hampshire places physician–patient communications on the same basis as attorney–client communications, except in cases where law enforcement officers seek blood or urine test samples and test results taken from a patient who is being investigated for driving while intoxicated.

United States In the United States, the Federal Rules of Evidence do not recognize doctor–patient privilege. At the state level, the extent of the privilege varies depending on the law of the applicable jurisdiction. For example, in Texas there is only a limited physician–patient privilege in criminal proceedings, and the privilege is limited in civil cases as well.

Australia In New South Wales, Australia, a privilege exists for "communication made by a person in confidence to another person [...] in the course of a relationship in which the confidant was acting in a professional capacity". This is often interpreted as being between a health professional and their patient. In some jurisdictions in Australia privilege may also extend to lawyers, some victims, journalists (shield laws), and priests. It may also be invoked in a public interest, or settlement negotiations, which may also be privileged.

England and Wales Unlike legal professional privilege that applies between lawyers and clients, there is no privilege between a doctor and patient under the laws of England and Wales. Doctors act under a duty of confidentiality to patients and the General Medical Council publishes guidelines on confidentiality that covers both the legal obligations and ethical duties of doctors towards patients. Public interest exceptions to the duty of confidentiality apply when it is necessary to protect third parties from serious harm, for notification of serious communicable diseases to others at risk, for safeguarding of vulnerable persons or those lacking capacity under the Mental Capacity Act 2005, and prevention of terrorism under the Terrorism Act 2000. Data about a person's health is treated as special category data under the General Data Protection Regulation (applied in the UK with the Data Protection Act 2018). The National Health Service Act 2006 also defines a category of "protected information" and sets restrictions on the disclosure of such information in the context of legal proceedings.

Worked examples

Example 1 — a first encounter with Physician–patient privilege

Start with the simplest possible case. Write down what Physician–patient privilege claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Physician–patient privilege before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Physician–patient privilege ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Physician–patient privilege

In research: Physician–patient privilege appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Physician–patient privilege in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Physician–patient privilege is common in secondary-school and first-year university syllabi. It links to neighbouring topics Health law, Medical doctors, Patient, so understanding it makes those chapters shorter.
In everyday life: Look for Physician–patient privilege outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
