Interest of the Intervention of a Nurse Coordinator in Complex Care Pathway

This project is based on the assumption that the nurse coordinators of the centres have common missions at each of the key stages of patient care. These missions make the care plan more fluid and improve the quality and safety of care as well as the patient's prognosis. The Hypothesis is that co-follow-up by a doctor and a nurse coordinator reduces time between referral to treatment, average lengths of stay, unscheduled readmissions or early emergency visits, compared to follow-up that does not involve a nurse coordinator.
