From a regulatory point of view, medication reconciliation is a necessary process to ensure safe medication management for patients. According to national studies and the international scientific literature, the information received by patients and health professionals at discharge from hospital is insufficient.

Medication reconciliation at discharge reduces medication errors and rehospitalisation, but few studies have been conducted on the impact of a coordinated and reliable care pathway on medication continuity.

The iCoCon study will enable a new healthcare organisation to be set up in order to improve the quality of the patient pathway and the patient's medication management.

This new organisation is part of the policy of continuous improvement of the quality and safety of care
