Documentation of influenza vaccination, including the specific product received, is critical to estimate annual vaccine effectiveness (VE).
We assessed performance of the Michigan Care Improvement Registry (MCIR) in defining influenza vaccination status relative to documentation by provider records or self-report among subjects enrolled in a study of influenza VE from 2011 through 2019.
The specificity and positive predictive value of MCIR were high; however, >10% of vaccinations were identified only by other sources each season. The proportion of records captured by MCIR increased from a low of 67% in 2013-2014 to a high of 89% in 2018-2019, largely driven by increased capture of vaccination among adults.
State vaccine registries, such as MCIR, are important tools for documenting influenza vaccination, including the specific product received. However, incomplete capture suggests that documentation from other sources and self-report should be used in combination with registries to reduce misclassification.
流感疫苗接种记录，包括接种的具体产品，对于估计年度疫苗有效性（VE）至关重要。
我们评估了密歇根州医疗改善注册系统（MCIR）在定义流感疫苗接种状态方面的表现，该系统是相对于 2011 年至 2019 年期间一项流感 VE 研究中通过提供者记录或自我报告来定义的。
MCIR 的特异性和阳性预测值均较高；然而，每个季节都有超过 10%的疫苗接种是通过其他来源确定的。MCIR 记录的比例从 2013-2014 年的低点 67%增加到 2018-2019 年的高点 89%，这主要是由于成年人的疫苗接种记录增加所致。
州疫苗登记系统，如 MCIR，是记录流感疫苗接种情况（包括接种的具体产品）的重要工具。然而，不完全的捕获表明，应结合登记系统使用来自其他来源的记录和自我报告，以减少分类错误。
