The hospital pharmacist plays a vital role at the time of the patient's first prescription in a healthcare facility, to inform the patient about his or her new therapy and create a link between the hospital and the patient's home pharmacy, so that the patient can continue to receive care at home. It is also essential that the hospital pharmacy and the patient's local pharmacy work together within a reasonable timeframe. This will help improve patient care and treatment follow-up, detect any undesirable effects and optimize their management..

The aim of this prospective interventional study is to measure the benefits of pharmaceutical monitoring in healthcare institutions at the initiation of oral therapy on patient compliance, side-effect management and adherence, in comparison with patients without this monitoring.

The primary endpoint is compliance with the Girerd questionnaire.
