Not How, But If: Determining the Need for Formal Capacity Evaluation.

Abstract

AbstractThe evaluation of decisional capacity is essential in clinical care, but limited guidance exists regarding when such assessments are necessary. Established models, such as Appelbaum and Grisso's "four skills" framework, provide guidance on how to assess capacity but do not address when and whether such evaluations should be conducted. This article proposes a three-step rubric to help clinicians determine whether a formal capacity assessment is justified. The first step emphasizes assuming capacity without evaluation unless reasonable uncertainty exists. The second step involves ascertaining whether the results of the evaluation would impact patient care. The third step requires weighing the potential benefits of the assessment against its costs vis-à-vis patient well-being. This rubric aims to reduce unnecessary evaluations, mitigate bias, and preserve patient autonomy by ensuring that capacity evaluations are conducted only when truly indicated.
