Downloaded from 5 6 Introduction 7 Drug-resistant Tuberculosis (DRTB) has become a serious concern globally and in China. Several 8 policies have been issued to improve DRTB case finding and treatment. We conducted a cascade 9 10 analysis on DRTB case finding and care in Zhejiang during 2015-2018 and explored the impacts of 11 these policies. 12 Methods 13 14 A questionnaire was designed to undertake a survey of all prefecture-level CDCs in Zhejiang on 15 DRTB-replated policies/programs active or introduced during 2015-2018. De-identified registration 16 data of presumptive and diagnosed DRTB patients from 2015-2018 in Zhejiang were used to 17 18 construct a seven-stepFor cascade peer of case finding review and care. Mixed-effect only two-level logistic regressions 19 were conducted to explore factors associated with patient registration, treatment initiation and 20 treatment completion. The DRTB policies active per prefecture per year were categorized according 21 to the combinations of policies on each step of the cascade, and included in the model to explore 22 23 their impacts. 24 Results 25 The number of reported presumptive DRTB patients and the percentage with drug susceptibility 26 27 testing (DST) records largely increased during 2015-2018, and the percentage of registered patients 28 that received anti-DRTB treatment also increased from 59.0% to 86.5%. Patients under the policies 29 of equipping GeneXpert plus expanded criteria for DST had a higher likelihood of being registered 30 31 compared with no GeneXpert (adjusted odds ratio, aOR=2.57), while for treatment initiation the 32 association was only when further expanding the registration criteria (aOR=2.38). Patients with 33 registered residence inside Zhejiang were more likely to be registered (aOR=1.96), treated 34 (aOR=3.83) and complete treatment (aOR=1.92) compared with those outside. 35 36 Conclusion http://bmjopen.bmj.com/ 37 The policy changes on DST and registration have effectively improved DRTB case finding and care. 38 Nevertheless, challenges remain in servicing the vulnerable group like the migrants and improving 39 40 equity in the access to TB care. Future policies should provide comprehensive support for migrants 41 to complete treatment at their current place of residence.
