OBJECTIVE This study aims to estimate the association between health information technology (HIT) use and influenza vaccine uptake among US adults. MATERIALS AND METHODS Data analysis was conducted using 2011-2015 National Health Interview Survey (NHIS) adult data (n = 169,912). HIT use was defined as having used computers (past 12 months) to seek health information, fill prescriptions, schedule appointments, communicate with health providers via email, and/or use online health chat groups. Crude and multivariable logistic regression models were used to estimate the odds of influenza vaccine uptake among HIT users versus non-users. Interactions were tested and stratified results were reported. RESULTS Among US adults, 39.8% received an influenza vaccine in the past 12 months, while 48.6% reported any HIT use. After adjusting for covariates, any HIT users had 1.23 times greater odds (95% CI = 1.19, 1.27) of influenza vaccine uptake relative to non-HIT users. HIT use for looking up health information on the internet (OR = 1.19, 95% CI = 1.15, 1.23), filling prescriptions (OR = 1.56; 95% CI = 1.50, 1.66), scheduling appointments (OR = 1.56; 95% CI = 1.50, 1.66), and communicating with providers via email (OR = 1.51; 95% CI = 1.44, 1.59) were significantly associated with influenza vaccine uptake. DISCUSSION HIT use is positively associated with influenza vaccine uptake. Each category of HIT use was independently associated with influenza vaccine uptake. To our knowledge, no other studies have evaluated the relationship between HIT use and influenza vaccine uptake. Our results are exploratory and represent an association, not a causal relationship. Longitudinal, confirmatory studies are also needed to verify our cross-sectional findings.

美国成年人中健康信息技术的使用和流感疫苗的使用。

目的本研究旨在评估美国成年人健康信息技术（HIT）使用与流感疫苗摄入之间的关联。材料与方法数据分析使用2011-2015年美国国家健康访问调查（NHIS）成人数据（n = 169,912）进行。HIT的使用被定义为使用计算机（过去12个月）来查找健康信息，填写处方，安排约会，通过电子邮件与健康提供者进行通信和/或使用在线健康聊天组。使用粗略和多变量逻辑回归模型来估计HIT使用者与非使用者之间接种流感疫苗的几率。测试了相互作用，并报告了分层结果。结果在美国成年人中，过去12个月中有39.8％的人接种了流感疫苗，而48.6％的人报告曾使用过HIT。调整协变量后，相较于非HIT使用者，任何HIT使用者的流感疫苗摄取几率高（1.23倍（95％CI = 1.19，1.27））。HIT用于在互联网上查找健康信息（OR = 1.19，95％CI = 1.15，1.23），填写处方（OR = 1.56; 95％CI = 1.50，1.66），安排约会（OR = 1.56; 95％CI = 1.50，1.66），以及通过电子邮件与提供者进行沟通（OR = 1.51; 95％CI = 1.44，1.59）与流感疫苗的摄取显着相关。讨论HIT的使用与流感疫苗的摄取呈正相关。使用HIT的每种类别都与流感疫苗的摄取独立相关。据我们所知，没有其他研究评估HIT使用与流感疫苗摄取之间的关系。我们的结果是探索性的，代表一种关联，而不是因果关系。纵，
