This pilot project was conducted in hard-to-reach communities of two Niger Delta States in the South-South Region of Nigeria.
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.
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.
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% ( < 0.001).
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.
本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。
使用世界卫生组织3B结核病筛查/诊断算法，评估便携式数字X射线设备德尔夫特轻型背包（DLB）在难以到达的尼日尔三角洲社区进行结核病主动病例发现（ACF）中的效用。
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进行社区结核病筛查外展活动期间，使用DLB X射线对所有同意参与的合格参与者进行筛查。CAD4TB（结核病计算机辅助检测评分）≥60的参与者接受了Xpert（痰液）和/或临床（X光片）结核病诊断评估。对该项目的数据进行了分析以用于本研究。
共有8230名参与者（男性：47.2%，女性：52.8%）接受了结核病筛查，确定了1140例（13.9%）疑似结核病病例。所有参与者和疑似结核病患者中的结核病患病率分别为1.2%和8.6%。筛查所需人数为84。在疑似结核病患者中，确诊为结核病的男性和女性比例分别为12.0%和5.6%（<0.001）。
在尼日利亚难以到达的尼日尔三角洲社区进行基于社区的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较高。建议在全国难以到达的地区推广使用该设备。
