We used the Pediatric Health Information System (PHIS) administrative database to compare the incidence of childhood tuberculosis at Children's National Medical Center (CNMC) in Washington, DC, with national rates and evaluated PHIS as an epidemiologic tool. The incidence rate of tuberculosis at CNMC was approximately twice that of the national PHIS rate (incidence rate ratio, 1.9; 95% confidence interval 1.4-2.5). Of the 51 cases listed by PHIS as tuberculosis at CNMC between 2003 and 2007, 41 represented active tuberculosis validated by internal chart review, with a positive predictive value of 80%.
我们使用儿童健康信息系统（PHIS）的行政数据库比较了华盛顿特区儿童国家医疗中心（CNMC）儿童结核病的发病率与全国发病率，并评估了 PHIS 作为一种流行病学工具。CNMC 的结核病发病率大约是全国 PHIS 发病率的两倍（发病率比，1.9；95%置信区间 1.4-2.5）。在 2003 年至 2007 年期间，PHIS 将 51 例结核病病例列在 CNMC 中，通过内部图表审查证实其中 41 例为活动性结核病，阳性预测值为 80%。
