[A health promotion campaign to improve flu vaccination adherence among medical residents in an Italian Teaching Hospital]

INTRODUCTION: In Italy annual flu vaccination for health care workers is recommended but coverage is usually unsatisfying. The compliance is even worse among medical residents (MRs) both in literature, both in our experience: in the flu season 2014/ 15 only 0.6% of MRs enrolled at the Università Cattolica del Sacro Cuore (UCSC) were vaccinated. For this reason, during the influenza season 2015/16, the Institute of Public Health of the UCSC, in collaboration with the Health Management of the "Agostino Gemelli" Teaching Hospital (FPG) and with the directive board of the Medical Specialization Schools (SSM) present at the University has tested several strategies to improve awareness and adherence to flu vaccination campaign by its staff. This study aims to analyze the impact of the strategies used during the 2015/16 campaign on flu vaccination coverage among MRs of an important Italian Teaching Hospital. METHODS: The study was conducted among MRs enrolled at the UCSC - FPG in 2015/16. The data was collected by the Occupational Medicine which, during the influenza seasons, immunize MRs against influenza free of charge. For each variable - vaccination, area of specialization (surgical, medical, clinical services), typology of SSM - was measured the absolute and percentage frequency. In order to compare the flu vaccination coverage between seasons 2014/15 and 2015/16 and between areas of specialization in 2015/16 chi-square test was used (statistical significance level of 0.05). The data were analyzed using STATA Software. RESULTS: Were included in the analysis 42 SSM with a total of 1041 MRs. During the vaccination campaign 2015/16, flu vaccine was administered to 99 MRs (9.5%), 8.9% more than in the previous season (p<0.001). There is also a significant difference in vaccine coverage between surgical, medical and clinical services areas in 2015/16 (p <0.001). The highest vaccination coverage was recorded among MRs of Hematology and Urology (54.5%). However, no one MRs had undergone flu vaccination in about 40% of SSM. CONCLUSIONS: Seasonal flu vaccination among HCWs is important to protect patients as well as them self and their family members. Considering that MRs represent the next generation of HCWs, they should be sensitized about the importance of preventing the spread of influenza in hospital population, becoming an active part of the necessary cultural change. This study highlights a first and promising, although insufficient, increase in flu vaccination coverage among MRs enrolled at the UCSC - FPG after introducing simple strategies to promote vaccination itself and, more generally, positive and proactive behaviors. The study summarizes the results in the short term, but it is well known that cultural changes require time and constancy. Therefore, it will be useful to monitor the improvement over time and extend the assessment to all health care professionals.
