The objective of this study was to validate physician billing claims against self-reported influenza vaccination to assess individual-level vaccination status. We compared responses to the Canadian Community Health Survey 1.1 (CCHS) and Ontario Health Insurance Plan (OHIP) physician billing claims and found moderate agreement. Using self-report as the gold standard, OHIP claims based on using both influenza-specific and general vaccination codes have high specificity and positive predictive value (PPV), reasonable negative predictive value (NPV), but only fair sensitivity. OHIP physician billing claims are suboptimal for ascertaining the vaccination status of individuals because many individuals receive their vaccinations outside doctor's offices, but may be used as the backbone for the creation of an immunization registry.
本研究的目的是对照自我报告的流感疫苗接种情况来验证医生计费索赔，以评估个体层面的疫苗接种状况。我们比较了加拿大社区健康调查1.1（CCHS）的答复与安大略省医疗保险计划（OHIP）的医生计费索赔，发现二者存在中度一致性。以自我报告作为金标准，基于同时使用流感特异性和一般疫苗接种代码的OHIP索赔具有较高的特异性和阳性预测值（PPV）、合理的阴性预测值（NPV），但敏感性仅为一般。OHIP医生计费索赔在确定个体疫苗接种状况方面并非最佳选择，因为许多人在医生办公室以外的地方接种疫苗，但可作为创建免疫登记册的基础。
