Objective: To investigate the influenza vaccination and its influencing factors among the clinical staff in Xining, Qinghai province, in the 2016-2017 influenza season, and to explore the promoting strategies to encourage the target population for influenza vaccination. Methods: Four sample hospitals were randomly selected from the total 11 tertiary hospitals in Xining city. Clinical staff that worked in the four hospitals and agreed to participate were recruited for investigation via a self-administered questionnaire. Results: During the 2016-2017 influenza season, the coverage rate of influenza vaccines among the clinical staff was 5.14% (95%CI: 4.80%-5.49%). Multivariate logistic regression showed that knowing the priority of vaccination, the frequency of vaccination, effect of vaccination, and possessing higher professional qualifications were major influencing factors for influenza vaccination. The intention on recommendation of seasonal influenza vaccine was higher in vaccinated group than that in the unvaccinated group (χ(2)=99.57, P<0.001). Conclusion: The lower coverage rate was primarily associated with the lack of knowledge about influenza vaccine among the clinical staff of the hospital. Tailored information should be provided to the clinical staff through effective methods to improve vaccination and the recommendation of influenza vaccine.目的： 了解青海省西宁市临床医护人员2016－2017年度流感疫苗的接种情况及影响因素，初步探索推动西宁市临床医护人员流感疫苗接种措施。 方法： 随机抽取西宁市4家三级医院，在知情同意的原则下自愿参与完成自填式问卷调查，并访谈医院相关负责人。 结果： 西宁市三级医院临床医护人员2016－2017年度流感疫苗接种率为5.14%（95%CI：4.80%~5.49%），多因素分析显示，流感疫苗优先推荐接种人群、接种频次，接种效果的知晓以及职称是主要影响因素。接种组向他人推荐流感疫苗的意愿高于未接种组（χ(2)=99.57，P<0.001）。 结论： 西宁市医院临床医护人员流感疫苗接种率低，主要与流感疫苗的认知不足有关。应开展宣传教育，充分发挥示范和影响作用。.
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。.
