Despite being the world's highest tuberculosis (TB) burden country, India still misses millions of TB cases annually. To address this issue, the India National Strategic Plan, following WHO strategy, promotes combining active case finding (ACF) with passive case finding (PCF) activities. National TB Elimination Programme (NTEP) began ACF campaigns thrice a year, targeting vulnerable populations. However, states like Manipur faced challenges in implementing and sustaining ACF activities due to resource constraints.
To assess the impact of engaging student and women organizations (SAWOs) in improving TB case notifications, treatment adherence, and completion rate in NTEP, as well as to estimate the cost-effectiveness of the ACF intervention.
A quasi-experimental pre-post study is being conducted among individuals ≥15 years residing in Senapati District, Manipur, having two phases: preparatory and enhanced case finding and implementation of the ACF. Data is being collected and compared on TB case notification, treatment adherence, and outcomes beforeand after the intervention. Chi-square test will be used to test the statistical significance and logistic regression to identify the factors independently associated with the impact of intervention. Potential confounders at both patient and facility levels will be identified based on expert opinion and bivariate analysis. A multi-level logistic regression model will be used to control the confounding, with sensitivity analysis to ensure result robustness.Cost analysis will cover direct, indirect, medical, and non-medical costs for patients and health system. Incremental cost-effectiveness ratio per quality-adjusted life years gained will be evaluated.
This study introduces a novel community-led model involving SAWOsto improve TB case detection and treatment support, comprehensively addressing allfour pillars of 'END TB' strategy. The intervention is a community-based participatory research, emphasizing collaboration between researchers andcommunity to address TB control. The main activities of this intervention include community TB sensitization, ECF, ACF, treatment support and monitoring. This model could significantly impact TB control efforts, especially in resource-constrained settings like Manipur, offering valuable insights into ACF implementation and its economic implications.
尽管印度是全球结核病负担最重的国家,但该国每年仍有数百万结核病病例未被发现。为解决这一问题,印度国家战略计划遵循世界卫生组织的战略,推动将主动病例发现(ACF)与被动病例发现(PCF)活动相结合。国家结核病消除计划(NTEP)每年开展三次针对弱势群体的主动病例发现活动。然而,像曼尼普尔邦这样的邦由于资源限制,在实施和维持主动病例发现活动方面面临挑战。
评估让学生和妇女组织(SAWOs)参与提高国家结核病消除计划中结核病病例通报、治疗依从性和完成率的影响,并估计主动病例发现干预措施的成本效益。
在曼尼普尔邦塞纳帕蒂区居住的15岁及以上人群中进行一项准实验性前后研究,分为两个阶段:准备阶段和强化病例发现以及主动病例发现的实施。收集并比较干预前后结核病病例通报、治疗依从性和结果的数据。将使用卡方检验来检验统计显著性,并使用逻辑回归来确定与干预影响独立相关的因素。将根据专家意见和双变量分析确定患者和医疗机构层面的潜在混杂因素。将使用多层次逻辑回归模型来控制混杂因素,并进行敏感性分析以确保结果的稳健性。成本分析将涵盖患者和卫生系统的直接、间接、医疗和非医疗成本。将评估每获得一个质量调整生命年的增量成本效益比。
本研究引入了一种由社区主导的新模式,涉及学生和妇女组织,以改善结核病病例检测和治疗支持,全面解决“终止结核病”战略的所有四个支柱问题。该干预措施是一项基于社区的参与性研究,强调研究人员与社区之间的合作以控制结核病。该干预措施的主要活动包括社区结核病宣传教育、强化病例发现、主动病例发现、治疗支持和监测。这种模式可能会对结核病控制工作产生重大影响,特别是在像曼尼普尔邦这样资源有限的地区,为主动病例发现的实施及其经济影响提供有价值的见解。
