    Abstract

    Patients with anatomical or functional hypo-/a-splenia have a 10- to 50-fold higher risk of developing severe infectious diseases than does the general population. Thus, it is recommended to adhere to a specific vaccination schedule, including receiving influenza vaccine. During 2014, Bari Policlinico General Hospital approved a specific protocol to ensure that vaccines are actively offered to all splenectomized patients during their hospitalizations. The aim of this study is to evaluate the efficacy of this active recall protocol for performing influenza vaccination in the years following splenectomy among patients still involved in a specific vaccination program carried out by the hospital's Hygiene department. From May 2014 to October 2016, 96 patients were involved in the vaccination program of the Hygiene department. In November 2017, 46/96 (48%) of patients received a specific invitation by phone to receive the annual influenza vaccine (intervention group), while 50/96 (52%) did not receive any such invitation (control group). At the end of the 2017 influenza season, 73/96 (76%; 95%CI = 66-84%) of patients reported having received the influenza vaccine; no differences were observed in the extent of vaccine coverage between the groups (intervention group = 80% vs. control group = 72%; p = 0.33). Older age, more recent splenectomy, hemo-lymphopathy and receiving the previous years' doses of influenza vaccine are associated with receiving influenza vaccination during the 2017 season. These data indicate how effective communication at the time of the vaccine counseling results in good adherence to the vaccination program even after several years. Indeed, vaccination should be an opportunity not only limited to the administration of the vaccine but also for providing patient care.
