Data_Sheet_1_Seasonal Influenza Vaccination at a German University Hospital: Distinguishing Barriers Between Occupational Groups.docx

The annual influenza vaccination has been officially recommended for medical staff in Germany since 1988. Nevertheless, the vaccination rate among medical staff is still low. The present study deals with the influenza vaccination rate of staff at a German University hospital over time as well as with the reasons that led to a positive vaccination decision and the barriers to acceptance of vaccination. For this purpose, the staff members received questionnaires in which they were asked about influenza vaccination and the reasons for or against vaccination. In addition, the questionnaire contains information on gender, age group, occupational group and presence of a chronic co-morbidity. Logistic regression analysis was used to investigate which of these predictors most strongly influenced the vaccination decision. It was shown that the reasons for or against vaccination differ significantly between the occupational groups and that the occupational group affiliation has the greatest influence on the vaccination decision in the comparison of the investigated predictors. In order to achieve a positive influence on vaccination acceptance, future measures should focus on increasing confidence in vaccination and on increasing the perception of risk from influenza illness. The findings may contribute to future targeted strategies to increase vaccination rates and suggest occupational group-specific interventions.

自1988年起，德国已正式将年度流感疫苗接种推荐给医务人员。然而，当前医务人员的流感疫苗接种率仍处于较低水平。本研究聚焦德国某大学附属医院（University Hospital）医务人员的流感疫苗接种率随时间的变化趋势，同时探讨促使其做出疫苗接种正向决策的动因，以及阻碍疫苗接种接受度的各类障碍因素。为此，研究人员向医务人员发放了调查问卷，内容涵盖流感疫苗接种情况、接种或拒种的相关动因；此外，问卷还收集了受访者的性别、年龄组别、职业类别以及是否存在慢性合并症等信息。本研究采用逻辑回归分析，探究上述预测变量中哪些对疫苗接种决策的影响最为显著。研究结果显示，不同职业组别间的接种动因或拒种理由存在显著差异，且在本次研究考察的各类预测变量中，职业类别归属对疫苗接种决策的影响最大。为对疫苗接种接受度产生积极影响，未来的相关干预措施应着重提升疫苗接种信心，并增强人们对流感疾病感染风险的认知。本研究结果可为未来制定提高疫苗接种率的针对性策略提供参考，并提示应针对不同职业类别开展差异化干预。
