Non-maleficence Duty

Uncertainty does not remove the obligation to act carefully. Clinicians should identify foreseeable harms, weigh them against the expected benefits of available options, and choose an intervention that is competent and proportionate. They should also take reasonable measures to reduce injury and communicate accurately, so that decisions remain ethically responsible even when the diagnosis or outcome is not fully established.

Proportionality asks whether the clinical burden imposed by an intervention is justified by its expected benefit. Complications and other harms should not be treated as incidental simply because treatment is intended to help. Examining this balance supports more careful choices about procedures and helps clinicians avoid interventions whose foreseeable risks are excessive relative to the likely patient benefit.

Competence reduces avoidable harm by linking an intervention to the clinician’s ability to perform and evaluate it appropriately. Under the Non-maleficence Duty, clinicians should consider whether they can provide the care safely and whether referral is more appropriate. This principle makes professional limits ethically relevant, particularly when a procedure, diagnosis, or treatment presents meaningful risk.

Application begins with a structured review of the proposed care. The clinician identifies foreseeable risks, considers the expected benefit, checks whether the intervention is competent and proportionate, and plans reasonable measures to reduce injury. Accurate communication and appropriate referral then help address uncertainty or limits in care, turning an ethical obligation into concrete safeguards for the patient.

Medication safety and infection prevention are direct clinical expressions of the Non-maleficence Duty. They focus attention on preventable sources of injury rather than only on the intended therapeutic result. Careful medication decisions, appropriate infection-prevention practices, and accurate communication can reduce avoidable harm while supporting patient welfare and professional accountability across routine care.

Reconsideration is warranted when foreseeable burdens or complications may outweigh expected benefits, when the intervention is not proportionate, or when competent care or referral is more appropriate. This review does not require eliminating every risk; it requires reasonable efforts to reduce injury and a defensible choice that protects patient welfare in the clinical circumstances.
