Transition points during hospitalization are at risk of drug related problems (DRP) especially admission and discharge. Reconciliation procedure at admission lead by a clinical pharmacist had been proved to decrease DRP. The community pharmacist (CP) is often the first health professional that patients meet at discharge. He/she is in charge of dispensing their medication to patients and give treatment information. However because of lack of information community pharmacist is not always able to identify problems and this may lead to dispense wrong drugs and/or wrong dosage and/or give wrong information. The objective of this study is to assess the impact of drug reconciliation performed at discharge completed by a communication between the Hospital Pharmacist (HP) and community pharmacist on drug related problem during the 7 days following discharge at home.
