This cooperative research project aims to conduct a randomised trial of a tailored intervention package to increase notifications of tuberculosis by private practitioners in Bandung, Indonesia. Mycobacterium tuberculosis isolated from notified TB cases will be sequenced to facilitate social network analyses and drug susceptibility testing. The project will be conducted as a collaboration between researchers at the University of Otago, the University of Padjadjaran (Indonesia) and Harvard University. It builds on our established collaboration in Indonesia on research on private practitioners and tuberculosis. This study is important as private practitioners diagnose around half of tuberculosis in Indonesia, but only rarely notify them and as such, the management of such cases is compromised. The sub studies will enhance understanding of transmission of Mycobacterium tuberculosis and inform a larger study in this area, and will provide important contextual information to help optimise the management of drug resistant tuberculosis cases in Indonesia.
