A Triad Approach to Best Interests when Responding to Discharge Demands from Hospitalized Patients Lacking in Mental Capacity to Decide on Treatment.

Hospitalized patients lacking the mental capacity to consent to treatment may demand to be discharged from the hospital against medical advice. Forced custody of these patients, including the use of restraints, may be required if the plan is to proceed with treatment. This raises ethical concerns with regard to depriving people of their liberty. The determination of the wishes and values of the patient and her best interests may sometimes vary, depending on the assessor or the clinical team entrusted to perform the evaluation. We therefore propose the following triad for clinicians when determining the best interests for this group of patients to ensure ethical and legal soundness as well as in providing consistency in approach. Firstly, the treatment should serve as a rescue response. Secondly, any restraint deployed must be proportionate with a foreseeable end. Her liberty and autonomy interests should be enhanced by the treatment. Thirdly, the patient's family must be supportive. This paper analyzes the use of the triad approach on two clinical cases, both assessed as lacking in mental capacity to decide on treatment and insisting to be discharged. Using this approach, we could justify how the contrasting outcomes, one in which the voluntary discharge was acquiesced versus the other, which was not acquiesced, were reached. We also examine the compatibility of the triad approach with the obligations under the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD).
