Theme 4: Treatment Delivery
Theme 4 studies factors that hinder provision of TB therapy and develops solutions to these issues. It conducts observational studies and operational research to define individual or systematic barriers (regulatory, financial, health systems) that impair optimal access to appropriate TB treatment or that impair outcomes from combination therapy. Theme 4 also focuses on developing and evaluating, through interventional studies, policy analyses and cost-effectiveness studies, new approaches to address these barriers. This includes approaches to improve current TB treatment delivery, such as novel models of observed therapy and inducing behavioral changes to enhance adherence to treatment, and strategies to maximise the impact of new tools and drugs when they are introduced into programmatic settings.
The theme also focuses of TB treatment delivery, such as novel models of observed therapy and inducing behavioral changes to enhance adherence to treatment.

mTB Genomic Database
Project PI: A/Prof. Teo Yik Ying
Project lead: Dr. Rick Ong
The project aims to create a comprehensive genomic database of drug-resistant TB strains, which will enable correlation of genotype differences in mTB genome to known phenotypic drug-resistance in South East Asia and help distinguish between neutral phylogenetic polymorphisms from mutations linked with partial or complete drug-resistance. mTB samples are collected in partnership with collaborators in Singapore, Thailand, Vietnam, Malaysia, Indonesia, Myanmar, and Cambodia.
Project lead: Dr. James Molton
Current means of optimising TB treatment adherence involves use of Directly Observed Therapy (DOT) which is inconvenient and costly for patients. It also poses logistical problems in remote rural populations. MIST (Mobile Interactive Supervised Therapy) develops a platform for smartphone-based treatment supervision and reminders to patients to enhance TB treatment regimen adherence.The aim of this study are to evaluate the performance, acceptability and efficacy of an electronic system for monitoring and supporting adherence to oral medications.
