ABSTRACT
INTRODUCTION:
Adherence to tuberculosis (TB) treatment remains a major challenge for disease control, particularly among migrant populations, who face linguistic, social, economic, and health service access barriers 1. Strategies that strengthen care monitoring and promote treatment continuity are essential to reduce treatment interruption and improve outcomes in this group 2. Video-Directed Treatment Observation (VDOT) has emerged as an alternative to conventional directly observed treatment (DOT), using digital technologies to remotely monitor medication intake 3. This approach may increase care flexibility, reduce operational costs and minimize barriers related to mobility and stigma experienced by migrants. This study aimed to evaluate adherence to tuberculosis treatment among migrants monitored through VDOT 4.
METHODS:
This is an observational, descriptive study with quantitative approach, conducted with international migrants diagnosed with TB, monitored through (VDOT). International migrants diagnosed with TB infection and disease and linked to health services were included. Adherence was assessed based on the record of doses observed, the regularity of video submissions, and follow-up throughout TB treatment. Data were analyzed using descriptive statistics, with calculation of absolute and relative frequencies for adherence indicators and treatment outcomes.
RESULTS:
Of the 78 migrants included in the VDOT follow-up, 61.5% (n=48) showed good acceptance of the strategy, progressing to completion of treatment; 2.6% (n=2) discontinued treatment; 34.6% (n=27) were undergoing treatment during the evaluation period, and 1.3% (n=1) were transferred to another country.
CONCLUSIONS:
VDOT proves to be a promising strategy for monitoring TB treatment in migrants, promoting therapeutic adherence, improving the quality of care provided, and reducing barriers to access to health services in vulnerable populations, in addition to highlighting the potential of digital technologies as auxiliary tools in monitoring care and strengthening health services.These findings support the feasibility of VDOT as a complementary strategy within tuberculosis control programs, particularly in contexts involving migrant and other vulnerable populations.
