Making healthcare decisions in a person's best interests when they lack capacity: clinical guidance based on a review of evidence.

One solution is to decide a strategic policy to cover more significant (usually health-related) decisions and to separate these from day-to-day relational decisions covering care and activities. Once persistent lack of capacity is confirmed, an early meeting should be arranged with family and friends, to start a process of sharing information about the patient's medical condition and their values, wishes, feelings and beliefs with a view to making timely treatment decisions in the patient's best interests.
