OBJECTIVE
This analysis examined the effectiveness of utilizing interferon-gamma release assay (IGRA) technology in a TB (TB) screening program at a university.
PARTICIPANTS
Participants were 2299 students at a Montana university who had presented to the university health center for TB screening during 2012 and 2013.
METHODS
A retrospective study was conducted utilizing data from student health center medical records. Time and financial expenditures were determined, and the cost of the present screening process and 2 alternative scenarios was calculated.
RESULTS
The current process is the most costly and time-consuming scenario for TB testing. Testing exclusively with IGRAs is the least labor-intensive for staff and creates revenue, whereas a dual method, utilizing IGRAs for high-risk students and skin tests for others, provides a solution that better responds to the demographic of the population.
CONCLUSIONS
This assessment shows that IGRAs are a cost-effective tool for screening a global student population.
目的
本分析检验了在一所大学的结核病（TB）筛查项目中利用γ-干扰素释放试验（IGRA）技术的有效性。
参与者
参与者为蒙大拿州一所大学的2299名学生，他们于2012年和2013年到大学健康中心进行结核病筛查。
方法
利用学生健康中心医疗记录中的数据进行回顾性研究。确定了时间和财务支出，并计算了当前筛查流程及两种替代方案的成本。
结果
当前流程是结核病检测中成本最高且最耗时的方案。仅使用IGRA检测对工作人员来说劳动强度最小且能产生收入，而对高危学生使用IGRA、对其他学生使用皮肤试验的双重方法提供了一种能更好地适应人群特征的解决方案。
结论
本评估表明，IGRA是筛查全球学生群体的一种具有成本效益的工具。
