让结核病 (TB) 确诊测试更便宜,更容易获得提供了比单独增加敏感性更大的人口健康益处. 然而,积极病例发现 (ACF) 的显著改进需要解决不仅仅是诊断测试之外的因素.
科学领域:
- 公共卫生 公共卫生
- 流行病学 流行病学
- 传染病建模 传染病建模
背景情况:
- 结核病 (TB) 的积极病例寻找 (ACF) 是由于成本,操作障碍和诊断工具的敏感性而受到限制.
- 优先考虑确认性测试的改进,需要了解它们的流行病学意义.
研究的目的:
- 模拟改善结核病确认测试对ACF活动结果的影响.
- 在固定预算的ACF模型中,比较当前与增强型诊断测试的有效性.
主要方法:
- 一个国家过渡模型模拟了一个以社区为基础的ACF活动,预算为100万美元.
- 与当前基于唾液的Xpert Ultra与假设的改进测试进行了比较 (更高的灵敏度,非唾液,护理点,成本降低).
- 评估了结核病诊断,死亡率和传染率在一个模拟的乌干达成年人群中,结核病患病率高.
主要成果:
- 在预算范围内,ACF目前的测试达到目标人群的30%,诊断了1,151例结核病例,避免了135例死亡.
- 提高灵敏度提高了结核病治疗人数15%,而降低测试成本 (降至10美元) 降低了11%的死亡率.
- 除了测试灵敏度之外的改进,如降低成本,产生了更大的死亡率降低.
结论:
- 降低成本和增加结核病确认测试的可用性,可能会给人口带来更大的健康益处,而不仅仅是增加敏感性.
- 对ACF健康影响的显著增长 (超过20%) 需要改善多个ACF组件,而不仅仅是诊断测试.
