When family caregivers are faced with making daily decisions, they may feel burdened, frustrated, and even in conflict with other family members. The OOVL Guide is a tool to help people think about the various aspects of a decision situation and combine them to make a decision. The OOVL Guide supports nurses in their advocacy role because it affirms the importance of the clients' values and preferences. The OOVL Guide provides decision-makers, both professionals and lay people, with a structure and procedure for making choices for themselves or others.
