Healthcare workers (HCWs) are at risk of influenza infection with associated nosocomial transmission. Sustained adherence to seasonal influenza vaccination uptake each year is important in epidemic control.
To assess the adherence of nurses to seasonal influenza vaccination over 5 years and its associated factors.
A cross-sectional study was conducted among nurses after the winter influenza season in Hong Kong in March 2019. Based on influenza vaccine uptake rates in the 2014/15-2018/19 seasons, respondents were stratified into three groups: 'full adherence' (vaccine uptake in five seasons), 'partial adherence' (vaccine uptake in one to four seasons) and 'non-adherence' (no vaccine uptake). Stepwise multi-variable logistic regression was performed to determine the associations between adherence to annual influenza vaccination, respondents' characteristics and considerations for vaccination.
Of 1306 nurses recruited, the majority were female (88%) with a median age of 36 years (interquartile range 30-46 years). The influenza vaccination uptake rate increased from 36% in the 2014/15 season to 47% in the 2018/19 season. After stratification, 39%, 40% and 21% of respondents were non-adherers, partial adherers and full adherers, respectively. Full adherence was significantly associated with female gender [adjusted odds ratio (aOR) 0.60], age ≥40 years (aOR 2.92), long-term care facility nurse (aOR 0.56), uptake during studentship (aOR 3.83), local prevalence of seasonal influenza (aOR 0.51) and expert opinion (aOR 4.04).
A limited proportion of nurses were fully adherent to seasonal influenza vaccination. Monitoring adherence, improving access to vaccines, and interventions targeting less-adherent HCWs are crucial.
医护人员面临感染流感及相关医院内传播的风险。每年持续坚持接种季节性流感疫苗对疫情控制至关重要。
评估护士在5年期间对季节性流感疫苗接种的依从性及其相关因素。
2019年3月香港冬季流感季节过后，对护士进行了一项横断面研究。根据2014/15至2018/19季节的流感疫苗接种率，将受访者分为三组：“完全依从”（五个季节均接种疫苗）、“部分依从”（一至四个季节接种疫苗）和“不依从”（未接种疫苗）。进行逐步多变量逻辑回归以确定年度流感疫苗接种依从性、受访者特征与接种考虑因素之间的关联。
在招募的1306名护士中，大多数为女性（88%），中位年龄为36岁（四分位间距30 - 46岁）。流感疫苗接种率从2014/15季节的36%增至2018/19季节的47%。分层后，分别有21%、40%和39%的受访者为完全依从者、部分依从者和不依从者。完全依从与女性性别显著相关[调整优势比（aOR）0.60]、年龄≥40岁（aOR 2.92）、长期护理机构护士（aOR 0.56）、学生时期接种（aOR 3.83）、季节性流感本地流行率（aOR 0.51）和专家意见（aOR 4.04）。
仅有有限比例的护士完全依从季节性流感疫苗接种。监测依从性、改善疫苗可及性以及针对依从性较低的医护人员进行干预至关重要。
