Objective-To evaluate the effectiveness of the role of a discharge coordinator whose sole responsibility was to plan and coordinate the discharge of patients from medical wards. Design-An intervention study in which the quality of discharge planning was assessed before and after the introduction of a discharge coordinator. Patients were interviewed on the ward before discharge and seven to 10 days after being discharged home. Setting-The three medical wards at the Homerton Hospital in Hackney, east London. Patients-600 randomly sampled adult patients admitted to the medical wards of the study hospital, who were resident in the district (but not in institutions), were under the care of physicians (excluding psychiatry), and were discharged home from one of the medical wards. The sampling was conducted in three study phases, over 18 months.Interventions-Phase I comprised baseline data collection; in phase II data were collected after the introduction of the district discharge planning policy and a discharge form (checklist) for all patients; in phase III data were collected after the introduction of the discharge coordinator. Main is crucial for good quality inpatient care and timely discharge from hospital. Good quality hospital discharge can be defined as patient satisfaction with involvement in the process of discharge, the absence of problems after discharge and the assessment, documentation, and meeting of the need for community care after discharge.A recent report from the National Health Service (NHS) Executive recommended that discharge coordinators should be appointed in hospitals to facilitate discharge planning.' An effective discharge planning process may be described as the construction and implementation of a planned programme of continuing care which meets a patient's needs after discharge from hospital. An adequate system of assessing patients' needs should also maximise the efficient use of hospital beds by ensuring that patients are not in hospital for an inappropriate time, or discharged with inadequate notice for the organisation of their continuing care at home. Essential elements of effective discharge planning are a multidisciplinary approach, early and coordinated assessment of a patient's needs and home circumstances, early planning of needs for further care, and effective communication. There is some evidence that the strict application of criteria for inpatient stays, reviewed daily by medical staff for each patient, can reduce the duration of stay.
