Abstract

Setting: This pilot project was conducted in hard-to-reach communities of two Niger Delta States in the South-South Region of Nigeria.

Objective: To assess the usefulness of portable digital X-ray, the Delft-Light Backpack (DLB) for TB active case-finding (ACF) in hard-to-reach Niger Delta communities using the WHO 3B TB screening/diagnosis algorithm.

Design: DLB X-ray was used to screen all consenting eligible participants during community TB screening out-reaches in all hard-to-reach communities of Akwa Ibom and Cross River States in the Niger Delta, Nigeria. Participants with a CAD4TB (computer-aided detection for TB score) ⩾60 had Xpert (sputum) and/or clinical (radiograph) assessment for TB diagnosis. Data from the project were analysed for this study.

Results: A total of 8,230 participants (males: 47.2%, females: 52.8%) underwent TB screening and 1,140 (13.9%) presumptive TB cases were identified. The TB prevalence among all participants and among those with presumptive TB were respectively 1.2% and 8.6%. The number needed to screen was 84. Among people with presumptive TB, the proportion of males and females with confirmed TB was respectively 12.0% and 5.6% (P < 0.001).

Conclusion: TB screening using DLB X-ray during community-based ACF in hard-to-reach Niger Delta communities of Nigeria showed a high TB prevalence among participants. Nationwide deployment of the instrument in hard-to-reach areas is recommended.

便携式数字x射线在尼日利亚农村社区用于结核病诊断前筛查。

环境:该试点项目在尼日利亚南南地区两个尼日尔三角洲州难以到达的社区开展。目的:评估便携式数字x线，Delft-Light Backpack (DLB)在难以到达的尼日尔三角洲社区使用WHO 3B结核病筛查/诊断算法进行结核病活动性病例发现(ACF)的有效性。设计:DLB x射线用于在尼日利亚尼日尔三角洲阿夸伊博姆州和克罗斯河州所有难以到达的社区结核病筛查外展活动中筛查所有同意的合格参与者。CAD4TB(计算机辅助检测结核病评分)大于或等于60的参与者进行了结核病诊断的Xpert(痰液)和/或临床(x光片)评估。本研究分析了该项目的数据。结果:共有8230名参与者(男性:47.2%，女性:52.8%)接受了结核病筛查，鉴定出1140例(13.9%)推定结核病病例。所有参与者和推定结核病患者的结核病患病率分别为1.2%和8.6%。需要筛选的人数是84人。在推定结核病患者中，男性和女性确诊结核病的比例分别为12.0%和5.6% (P < 0.001)。结论:在尼日利亚难以到达的尼日尔三角洲社区，社区ACF期间使用DLB x射线进行结核病筛查显示参与者中结核病患病率很高。建议在难以到达的地区在全国范围内部署该仪器。
