India is experiencing a regional increase in cases of multidrug-resistant tuberculosis (MDR-TB). Given the complexity of MDR-TB diagnosis and care, we sought to address key knowledge gaps in MDR risk factors, care delays, and drivers of delay to help guide disease control. From January 2018 to September 2019, we conducted interviews with adults registered with the National TB Elimination Program for MDR ( = 128) and non-MDR-TB ( = 269) treatment to quantitatively and qualitatively study care pathways. We collected treatment records and GeneXpert-TB/RIF diagnostic reports. MDR-TB was associated with young age and crowded residence. GeneXpert rifampicin resistance diversity was measured at 72.5% Probe E. Median time from symptom onset to diagnosis of MDR was 90 days versus 60 days for non-MDR, Wilcoxon < 0.01. Delay decreased by a median of 30 days among non-MDR patients with wider access to GeneXpert, Wilcoxon = 0.02. Pathways to care were complex, with a median (interquartile range) of 4 (3-5) and 3 (2-4) encounters for MDR and non-MDR, respectively. Of patients with MDR-TB, 68% had their first encounter in the private sector, and this was associated with a larger number of subsequent healthcare encounters and catastrophic expenditure. The association of MDR with young age, crowding, and low genotypic diversity raises concerns of ongoing MDR transmission fueled by long delays in care. Delays are decreasing with GeneXpert use, suggesting the need for routine use in presumptive TB. Qualitatively, we identify the need to improve patient retention in the National TB Elimination Program and highlight patients' trust relationship with private providers.
印度的耐多药结核病(MDR-TB)病例呈区域性增加。鉴于 MDR-TB 诊断和治疗的复杂性,我们试图解决 MDR 风险因素、治疗延迟以及导致延迟的驱动因素方面的关键知识空白,以帮助指导疾病控制。从 2018 年 1 月到 2019 年 9 月,我们对登记在国家结核病消除计划中的耐多药(MDR)( = 128)和非耐多药-TB( = 269)治疗的成年人进行了访谈,对治疗途径进行了定量和定性研究。我们收集了治疗记录和 GeneXpert-TB/RIF 诊断报告。MDR-TB 与年龄较小和居住拥挤有关。在 72.5%的探针 E 处测量 GeneXpert 利福平耐药多样性。MDR 症状出现到诊断的中位时间为 90 天,而非 MDR 为 60 天,Wilcoxon < 0.01。非 MDR 患者中,GeneXpert 可获得性增加后,中位延迟时间减少了 30 天,Wilcoxon = 0.02。治疗途径复杂,MDR 和非 MDR 的中位数(四分位距)分别为 4(3-5)和 3(2-4)次就诊。MDR-TB 患者中,有 68%的人首次就诊于私营部门,这与随后更多的医疗保健就诊次数和灾难性支出有关。MDR 与年龄较小、拥挤和较低的基因型多样性有关,这令人担忧的是,由于治疗延迟时间长,MDR 传播仍在继续。随着 GeneXpert 的使用,延迟时间正在减少,这表明需要常规用于疑似结核病。从定性角度来看,我们发现需要改善国家结核病消除计划中患者的保留率,并强调患者与私营机构提供者之间的信任关系。
