Résumé
Today, vaccination is a major preventive strategy for public health. Adulthood is a key period for vaccination due to boosters and specific vaccine recommendations related to age, immune status or comorbidities. Vaccination coverage in this population is still largely insufficient. Although general practitioners are the first effectors for vaccination, its process is heterogeneous with multiple participants and varied determining factors. In light of this, a specialised consultation has been set up in the Bassin de Thau hospitalisation centre to try to improve the vaccination coverage with the primary endpoint being improving vaccination coverage for 50% of patients who were eligible for at least one vaccine according to the national vaccination schedule. This observational, prospective, monocentric study was conducted on 197 patients hospitalised between November 2022 and June 2023 and consisted of a two stage evaluation: stage one collecting information related to the vaccination history and stage two updating vaccination during a post-hospitalisation consultation. Evaluation of vaccination coverage and user satisfaction were provided secondarily. In total, from the 191 eligible patients, 80 patients (42%) were able to receive at least one of the indicated vaccines (p= N.S.) they had not been updated with before. The acceptability rate was above 90%. Vaccination coverage has been greatly improved for all the vaccines studied with a significant difference for DTP, pneumococcal and zoster vaccines. However, 39% of our patients were lost to follow-up before the first consultation. As a result, hospitalisation became a missed opportunity for vaccination. These results confirm the need to seize hospitalisation to focus on preventative measures; subject to a financial support from the institutions, a strengthening of the collaboration between ambulatory medicine and hospital care and the optimisation of traceability.
