Patients with Pulmonary Arterial Hypertension (PAH) require multidisciplinary care. Involving pharmacists in PAH multidisciplinary care teams may enhance patient education and improve medication use. We describe the implementation of a Pharmacist Collaborative Care Program (PCCP) in a PAH referral centre in Grenoble, France. Initiated in 2007, the PCCP program includes a pharmacist intervention whose goals are educational, psychosocial, and technical. During patient interviews, pharmacists make an 'educational diagnosis' and provide a patient-specific education session. Patient skills are evaluated at the end of the session. Pharmacists provide feedback to nurses and physicians through a standardized report form and discussion during medical rounds and PAH group meetings. Pharmacists re-evaluate patients' skills every 3-6 months during multidisciplinary clinical evaluations. The PCCP program for PAH is an established practice in Grenoble and may inform future patient education programs involving pharmacists in France, where legislation has recently been passed to standardize patient education.
