The term âfutilityâ is used to refer to the inability of a clinical trial to achieve its objectives. In particular, stopping a clinical trial when the interim results suggest that it is unlikely to achieve statistical significance can save resources that could be used on more promising research.
Like legal capacity, clinical capacity is specific to a particular health care decision and is limited to that decision. A person may have the clinical capacity to make a basic health care decision (for example, receiving IV fluids) but may not be able to decide whether to participate in a clinical trial. Also, clinical incapacity is not necessarily permanent.
