A 55-year-old man undergoes elective laparoscopic cholecystectomy. The surgeon performs an open conversion due to dense adhesions but fails to document this complication or inform the patient postoperatively. The patient later discovers the conversion and sues for negligence. Which feature best distinguishes **breach of duty** from **causation of harm** in this negligence claim?

Explanation

## Breach of Duty vs. Causation of Harm in Professional Negligence ### The Four Elements of Negligence For a successful negligence claim, all four must be proven: 1. **Duty of care** — physician owes a legal duty to the patient 2. **Breach of duty** — deviation from the standard of care 3. **Causation** — breach caused the harm 4. **Damage** — actual injury or loss resulted ### Breach of Duty vs. Causation: The Discriminator | Aspect | Breach of Duty | Causation of Harm | | --- | --- | --- | | **Definition** | Failure to meet the standard of care owed to the patient | Direct causal link between the breach and the injury suffered | | **Focus** | Physician's conduct and deviation from expected standard | Outcome and whether the breach caused the damage | | **Test (India)** | **Bolam test**: Would a reasonable physician in the same circumstances act similarly? | **But-for test**: But for the breach, would the harm have occurred? | | **Example** | Failure to disclose material risks = breach | Patient's actual injury from the undisclosed risk = causation | | **In this case** | Failure to document/disclose conversion = breach | Patient's psychological harm from non-disclosure = causation | ### Key Point: **Breach of duty is about the physician's conduct (deviation from standard of care). Causation is about the link between that conduct and the patient's actual harm.** ### High-Yield: In the given scenario: - **Breach**: The surgeon failed to disclose the conversion—a material fact that a reasonable surgeon would disclose. - **Causation**: The patient must prove that the non-disclosure caused them harm (emotional distress, loss of trust, or inability to seek second opinion). A breach without causation does not result in liability; a causation without breach does not result in liability either. ### Mnemonic: **DBCD** — **Duty, Breach, Causation, Damage**. Breach is step 2 (conduct); Causation is step 3 (outcome link). ### Clinical Pearl: Many surgeons assume that if they performed the surgery correctly (even if conversion was necessary), there is no negligence. However, **failure to disclose the conversion is a breach of the duty to inform**, regardless of the surgical outcome. The patient must then prove causation—that this non-disclosure caused them quantifiable harm.
