We analysed the impact of several strategies aimed at increasing influenza immunisation rates among Medical Residents (MRs) of an Italian teaching Hospital. During the 2015-16 and 2016-17 influenza seasons we carried out several interventions: ambulatory doubling where vaccination was offered, ambulatory opening hour extension, email invitations, informative materials, forum theatre and vaccination campaign conference. In addition, during the 2016-17 the OSV was carried out: MRs who go to specific wards where they perform influenza immunisation counselling and eventually vaccinate the personnel. 99/1041 (9.5%) and 184/1013 (18.2%) MRs received the vaccine in 2015-16 and in 2016-17 respectively (p < 0.0001). Significant difference was found among three specialisation areas (medicine, surgery, "services"; p < 0.001) and among years of residency (p < 0.001). The highest coverage was found among Infectious Diseases, Paediatrics, Haematology and Hygiene MRs (80%, 67%, 52% and 52% respectively) in 2016-2017 season. The highest coverage increase was found among MRs in Pneumology and Geriatrics (566% and 268%, respectively). The coverage rate has increased even though important differences among specialties persist. The study shows a significant increase in immunisation rate among MRs after the implementation of these strategies.
