Despite partners and relatives providing care prior to a hospital admission, all too often they are not involved or informed about the treatment process during a patient's stay in hospital. The primary nurse system is an effective way of delivering care within the mental health framework. The primary nurse is responsible and accountable for the patient throughout his/her stay in hospital. Peplau's model of nursing care concentrates on the development of the nurse-patient relationship. Care plans should be negotiated with the patient. Care plan meetings are useful for discussing problems, receiving feedback and for supporting colleagues. Family meetings are essential so that the main carer's continuing involvement in care can be acknowledged.
