In the strained actual economic context, all clinical pharmacy activities cannot be achieved for all patients of all care pathways. So finding a way to prioritize moments and patients needing those activities is essential. This is the challenge of the "5P project" (Patient personalized clinical pharmacy program integrated into care pathway). To present adverse event (AE) risk management approach applied to develop clinical pharmacy programs integrated into care pathway, using two methods. Used as a priori AE risk management approach, the Delphi method and inductive approach analysis of semi-directed interviews were realized from April 1st to October 3rd, 2019, respectively in orthogeriatric (OG) and pediatric kidney transplantation (PKT) care pathways. Complementarily to bibliographic research, participants were medical and paramedical healthcare providers involved in the concerned care pathway. They have been interrogated regarding AE risks to identify the clinical pharmacy activities required, the patients who need them, and the appropriate steps of the care pathway. The Delphi method for OG care pathway has revealed: 1/. Patients were prioritized by the presence of at least 2 among the following 4 criteria: age ≥90 years old, cardiovascular diseases, prescribed potentially inappropriate medication for elderly patients, obesity or diabetes; priority steps were the post-operative and rehabilitation care steps. 2/. Prescription reviews, medication reconciliation and targeted pharmaceutical informative interview about oral anticoagulants were required. Nine semi-directed interviews used for PKT care pathway has revealed: 1/. Clinical pharmacy activities were carried out for all patients. Priority steps were pre-transplantation, immediate post-operative, and post-transplantation. 2/. Prescription reviews and educative interviews were required. The two presented methods can be used to both develop patient prioritization and targeting steps for clinical pharmacy activities, and integrate it into care pathway. Today, those two developed programs have been executed in our teaching hospital.
