Prevention of Pneumococcal Infections: Impact Collaborative Medico-pharmaceutical Care Structured to Improve Vaccination Coverage of Patients at Risk. (OPTIVACC)

November 26, 2025 updated by: Centre Hospitalier Universitaire de Nīmes
In France, Streptococcus pneumoniae is the leading agent bacterial involved in community lung disease and meningitis. The frequency of these infections and their mortality increase significantly in those at risk such as patients with certain chronic diseases, immunocompromised or on immunosuppressive therapy. This population, despite regular monitoring, has a limited pneumococcal vaccine coverage of around 20%. By carrying out a reconciliation of treatments upon admission to hospital, the clinical pharmacist can detect those without up to date pneumococcal vaccination status. The goal of this management is to make the patient aware of the need for vaccination and organization upon return home. Thus, this limited pneumococcal vaccination coverage would benefit from intervention by regional clinical pharmacy activities. The study investigators want to study the impact of a structured medico-pharmaceutical collaboration on pneumococcal vaccination of patients with risk on discharge from hospital. The investigators hypothesize that this collaboration in patients at risk of infection with pneumococcus could significantly increase their anti-pneumococcal vaccination coverage
