Decision making Decision making capacitycapacity: determined by : determined by cliniciansclinicians
CompetenceCompetence for decision making: for decision making: determined by the courtdetermined by the court
“Core meaning” of competence: “The ability to perform a task.” Beauchamp
Are capacity and competence different in terms of ethics or effect, or merely different in terms of who decides?
Decision making capacity
““In medical contexts, for example, a person In medical contexts, for example, a person is usually considered competent if able to is usually considered competent if able to understand a therapeutic or research understand a therapeutic or research procedure, to deliberate regarding its major procedure, to deliberate regarding its major risks and benefits, and to make a decision in risks and benefits, and to make a decision in light of this deliberation.”light of this deliberation.”
Beachamp & Childress
Linkage of capacity to the decision Classic teaching: decision making capacity Classic teaching: decision making capacity
is determined relative to particular decisionsis determined relative to particular decisions Patients may have capacity for some Patients may have capacity for some
decisions and not othersdecisions and not othersExample: a patient with dementia may Example: a patient with dementia may
be able to chose to take a pain pill, but be able to chose to take a pain pill, but not whether to have a particular not whether to have a particular surgerysurgery
Problems with linking capacity to individual decisions: Competence vs. capacity: as competence is Competence vs. capacity: as competence is
a time-consuming procedure – more a a time-consuming procedure – more a determination regarding the determination regarding the patientpatient than the than the decision – medical decisions tend to be decision – medical decisions tend to be “bundled” in competency determinations“bundled” in competency determinations
