Study of the Impact of an Intervention Performed by a Clinical Pharmacist on Patients at Risk of Pneumococcal Infection at the End of Hospitalization

In France, Streptococcus pneumoniae is the leading agent involved in community-acquired bacterial pneumopathies and bacterial meningitis. The frequency of these infections is increasing in at-risk subjects. Paradoxically, pneumococcal vaccination coverage in this type of patient is limited at the national level, even though the French High Council for Public Health (HCSP) has been extending the 13-valent conjugate and 23-valent non-conjugate double vaccination in this target population since March 2017.

These patients generally benefit from regular medical follow-up involving several health professionals in hospital or outpatient clinics. In spite of this, one of the factors identified as a hindrance to pneumococcal vaccination is the absence of a proposal from the doctor.

We would like to assess compliance with the recommendations for pneumococcal vaccination according to the High Council of Public Health (HCSP) in at-risk patients leaving hospital. We also wish to measure the potential impact of an intervention by the clinical pharmacist on the application of these recommendations.
