Medication reconciliation (MR) will be done for patients hospitalized in the French referral center for PH for PAH or CTEPH. Detected medication errors will be tracked and fixed by the physician before the end of hospitalization. A synthesis of new/stopped and modified treatments will be given to the patient as well as his related healthcare professionals (community pharmacist and general practioner) to ensure the maintaining of the new therapeutic management and the understanding of drugs modification. To compare the potential decrease of medication errors promoted by MR, a retrospective MR will be also done for patients without MR at 1st hospitalization but at the next one (3 to 6 months after).
Pulmonary hypertension (PH) is a life threatening condition. In PH, pulmonary arterial hypertension (PAH) and chronic thrombo-embolic chronic pulmonary hypertension (CTEPH) are two rare diseases requiring specific and complex drug management. In France ,a part of these treatments ,only available in hospital pharmacies, are generally unknown from community health care professionals despite the high risk of drug-interactions and side effects. Anticipating medication errors at the begging of the disease is therefore important, and could be done through medication reconciliation.
