Abstract

Setting: Despite recent progress in TB notification rates, 6.2% of the 3.1 million 'missing' people with TB globally are from Nigeria. Identifying these 'missing' cases will improve TB control efforts in Nigeria.

Objective: This paper aims to describe the outcome of an intensified TB case-finding strategy in northern Nigeria.

Design: An intensified TB case-finding strategy was implemented in four states in northern Nigeria from October 2021 to September 2022. Trained ad-hoc staff screened hospital attendees and linked identified persons with presumptive TB to diagnosis using a hub and spoke approach. People with confirmed TB were linked to treatment. Contributions of the strategy to the national TB notification rates for each state were assessed.

Results: A total of 1.17 million individuals were screened for TB across the four project States. 64,079 people with presumptive TB were identified, of which 10.1% were diagnosed with TB and 97% of those diagnosed were placed on treatment. Averagely, 33.3% of the TB cases notified from each state were contributions from the hospital-based Intensified TB case-finding intervention.

Conclusion: Facility-based intensified TB case-finding results in significant improvement in TB notification rates and a good strategy to improve the identification of missing TB cases in Nigeria.

在尼日利亚北部寻找失踪结核病病例。

环境：尽管最近在结核病通报率方面取得了进展，但全球310万“失踪”结核病患者中有6.2%来自尼日利亚。确定这些“失踪”病例将改善尼日利亚的结核病控制工作。目的：本文旨在描述尼日利亚北部加强结核病病例发现战略的结果。设计：2021年10月至2022年9月在尼日利亚北部四个州实施了强化结核病病例发现战略。训练有素的临时工作人员对医院就诊人员进行筛查，并使用中心辐射式方法将已确定的推定结核病患者与诊断联系起来。确诊结核病患者需要接受治疗。评估了该战略对各州全国结核病通报率的贡献。结果：在四个项目州共对117万人进行了结核病筛查，确定了64,079名推定结核病患者，其中10.1%被诊断为结核病，97%的确诊患者接受了治疗。平均而言，每个州通报的结核病病例中有33.3%来自以医院为基础的强化结核病病例发现干预措施。结论：在尼日利亚，以设施为基础的强化结核病病例发现显著提高了结核病报告率，是提高漏报结核病病例识别的良好策略。
