What ethical concern does medical futility raise in end-of-life decisions?

• A. Futility means any intervention that extends life.
• B. Futility refers to interventions unlikely to benefit the patient and can guide the discontinuation or withholding of ineffective treatments.
• C. Futility requires physician-only decision-making.
• D. Futility always obligates continued treatment.

Answer: (B)

Medical futility in end-of-life decisions centers on whether an intervention is likely to benefit the patient. If a treatment has little or no chance of improving meaningful outcomes—such as survival, function, or quality of life—it’s considered futile. In those cases, continuing the intervention offers little value and can cause harm, burdens, or suffering, so it may be appropriate to withhold or discontinue it. This view supports aligning care with the patient’s goals and overall welfare, rather than pursuing treatments that won’t help.

Two important nuances help explain the concept further: futility can be quantitative (very low probability of benefit) or qualitative (benefit would be so limited in quality that it’s not worthwhile). Decisions about futility often involve discussion with patients and families, and may include ethics consultations, because they touch on values, preferences, and the physician’s professional judgment about appropriate care. Importantly, recognizing futility does not require forcing continued treatment; rather, it can justify stopping or not starting ineffective care.

Interventions that merely extend life without real benefit are not necessarily futile, and decisions about futility rely on the likely impact on the patient, not on the mere possibility of life extension. It also does not mean only physicians decide; patient autonomy, family input, and multidisciplinary perspectives all play roles in determining appropriate care.
