Impacts of a Comprehensive TB Control Model on the Quality of Clinical Services and the Financial Burden of Treatment for Patients with Drug-resistant Tuberculosis in China: A Mixed-methods Evaluation
Abstract IntroductionDrug-resistant tuberculosis (DRTB) has become a critical challenge to ending TB efforts worldwide. To help address the burden in China, the China National Health Commission-Gates TB Project Phase III implemented a comprehensive TB control model which includes multiple interventions to improve the quality of clinical services and reduce the financial burden for DRTB patients.MethodsA mixed-methods approach was used to evaluate the effectiveness of interventions. The quantitative data included three sources: de-identified DRTB registered data from 2015-2018 in project provinces, medical records of DRTB patients registered in 2018 (n=106), and a structured DRTB patient survey in six sample prefectures. The quality of clinical services was evaluated using seven indicators across patient screening, diagnosis and treatment. Logistic regression was conducted to explore factors associated with the extremely high financial burden (defined as out-of-pocket medical expenditure in the first six months of treatment over 30% of annual household income). Key informant interviews with policymakers and focus group discussions with physicians and DRTB patients were conducted to understand the interventions implemented and their impacts.ResultsThe percentage of bacterially confirmed patients taking a drug susceptibility test (DST) increased significantly between 2015 and 2018: from 57.4% to 93.6% in Zhejiang, 12.5% to 86.5% in Jilin, and 29.7% to 91.4% in Ningxia. The treatment enrollment rate among diagnosed DRTB patients also increased significantly and varied from 73% to 82% in the three provinces in 2018. Over 90% of patients in Zhejiang and Jilin and 75% in Ningxia remained in treatment by the end of the first six months’ treatment. Among all survey respondents 77.5% incurred extremely high financial burden of treatment. Qualitative results showed that interventions on promoting rapid DST technologies and patient referral were successfully implemented, but the new financing policies for reducing patients’ financial burden were not implemented as planned.ConclusionsThe quality of DRTB related clinical services has been significantly improved following the comprehensive interventions, while the financial burden of DRTB patients remains high due to the delay in implementing financing policies. Stronger political commitment and leadership are required for multi-channel financing to provide additional financial support to DRTB patients.
