The following can act as a personal representative of an adult:
1. a person with a durable power of attorney for health care;
2. an adult appointed by a patient as their health care proxy; or
3. a court-appointed guardian.
For research participation, there is one more option. Oklahoma Statute, 63 Okla. Stat 3102A, provides that a legal guardian, attorney-in-fact, and certain enumerated family members can consent to a patient’s participation in a research study being conducted by a University faculty member if the study has received IRB approval.
