In this episode of OT Conversations, Hao, an occupational therapist, discusses the concept of capacity assessment. Capacity assessment is a formal evaluation to determine an individual's ability to make informed decisions regarding their health, finances, legal matters, daily activities, and other life aspects. It is critical in medical, legal, and therapeutic settings and aims to evaluate cognition, emotional, and functional abilities. The talk covers the objectives of capacity assessment, such as ensuring decision-making ability, safety, legal and medical guidance, and support for rehabilitation planning. It identifies the populations needing capacity assessments, including those with neurological conditions, the elderly, individuals with mental disorders, critical care patients, and those with intellectual or developmental disabilities. Key areas evaluated include medical, financial, legal, daily living, and mental and emotional capacities. The assessment methods include clinical observations, standardized tests, functional assessments, legal reviews, and obtaining collateral information. The potential outcomes of capacity assessment are full capacity, partial capacity, or lacking capacity. Ethical considerations and biases should be managed, and respect for the individual’s autonomy and the use of the least restrictive measures are emphasized. Capacity should be reassessed over time as it can fluctuate.
