Objective: To evaluate the current status and related factors of influenza vaccination among health care workers (HCWs) in tertiary hospitals of Xining city after the implementation of the free influenza vaccination policy. Methods: In August 2018, the cluster sampling method was used to select four medical institutions in Xining that had previously conducted investigations and interventions. All HCWs(excluding logistic staff) in each medical institution were included in the study. A total of 3 260 valid respondents were included. Questionnaires were used to collect the demographic characteristics, influenza and influenza vaccination awareness, implementation of free policy in the influenza epidemic season from 2017 to 2018, influenza vaccination status, awareness of influenza vaccination schedule and free policy. The multivariate logistic regression model was used to analyze related factors of influenza vaccination. Results: The age of respondents was (31.41±5.00) years. The influenza vaccination rate was 6.80% (226/3 260) in 2017-2018 influenza epidemic season. After controlling for related factors, the awareness of the influenza vaccination schedule (OR=17.05, 95%CI: 5.86-49.59), vaccination frequency (OR=8.22, 95%CI: 2.98-22.61) and the free policy (OR=3.15, 95%CI: 1.49-6.67) had higher vaccination rate. Conclusion: The influenza vaccination rate of HCWs in tertiary hospitals of Xining city was low. Increasing the awareness of the vaccination schedule, frequency and free policy may promote the influenza vaccination rate of HCWs.
目的: 了解流感疫苗免费接种政策实施后西宁市三级医院医务人员的流感疫苗接种率及其相关因素。 方法: 于2018年8月,采用整群抽样的方法,将西宁4家既往开展过调查干预的医疗机构的所有医务人员(工勤人员除外)纳入研究,共纳入3 260名研究对象。采用问卷收集人口学特征、流感及流感疫苗的认知情况、2017—2018年流感流行季节免费政策实施情况、流感疫苗接种情况、知晓流感疫苗接种时间和免费政策等信息,并采用多因素logistics回归模型分析流感疫苗接种的相关因素。 结果: 研究对象年龄为(31.41±5.00)岁,2017—2018年流感流行季节的流感疫苗接种率为6.80%(226名)。与不知晓流感疫苗接种时间、免费接种政策者相比,知晓流感疫苗接种时间、流感疫苗每年接种一次、免费政策者的流感疫苗接种率较高,OR(95%CI)值分别为17.05(5.86~49.59)、8.22(2.98~22.61)、3.15(1.49~6.67)。 结论: 2017—2018年流感流行季节西宁市三级医院医务人员的流感疫苗接种率较低;提高流感疫苗接种时间、接种频次和免费政策的知晓率可能增加流感疫苗接种率。.
