Ethics of FutilityEthics of Futility
• Oldest principles (fiduciary relationship)– Beneficence– Non-maleficence
• Newer principles– Autonomy– Justice

1997: AMA, SCCM, ATS, ACCP– ethical and legal propriety of limiting unwanted
treatment, necessity of pall care

who are overmastered by their diseases, realizing that in such cases medicine is powerless”

• Achieving consensus• Determining & Following patient preferences• Estimating prognosis• Evaluating benefit• Physician fears• Balancing individuals & society: resource

Achieving ConsensusAchieving Consensus
• Cannot agree on the definition• In the eye of the beholder,
subjective/personal:a) is unlikely to be of any benefit to a
particular patient in a particular medical situation
b) will not achieve the patient’s intended goals
Helft. N Engl J Med. 2000;343:293-296.

Determining & FollowingDetermining & Following Patient PreferencePatient Preference
• AD may not be present• AD may not be specific enough• Surrogates may be unrealistic
– No improved mortality– Increased cost

Estimating PrognosisEstimating Prognosis• We’re poor at prognosticating• RNs and MDs don’t agree on futility
– Docs and RNs not agree in 63% of dying– Cannot predict QOL– RNs more pessimistic, more correct
Frick S et al. Crit Care Med. 2003 Feb;31(2):456-61.

Physician Fears of LitigationPhysician Fears of Litigation
• Generally, courts don’t want to be involved• Only 11 states have laws requiring
treatment with no time limit to allow transfer
• Almost always support physician decisions– Especially Ex Post (duty, breach, direct
causation, damages)– Ex Ante sometimes injunctions are ordered to
allow transfer

• We don’t agree on what it is• We don’t agree on how to evaluate the benefit
of interventions• We can misuse the futility argument
• 33% used the argument of Quantitative Futility but estimated the chance of survival to be 0-75%
• 18% used the argument of Qualitative Futility, but only 1/3 discussed QOL
