Tuberculosis Among Economic Migrants: A Cross-Sectional Study of the Risk of Poor Treatment Outcomes and Impact of a Treatment Adherence Intervention Among Temporary Residents in an Urban District in Ho Chi Minh City

This cross-sectional study evaluated WHO-defined TB treatment outcomes among economic migrants in an urban district of Ho Chi Minh City, Viet Nam. We measured the association of a patient’s government-defined residency status with treatment success and loss to follow-up categories at baseline and performed a comparative interrupted time series (ITS) analysis to assess the impact of community-based adherence support on treatment outcomes. Key measures of interest of the ITS were the differences in step change (β₆) and post-intervention trend (β₇).
