Objective:
To explore patient perspectives on using a digital adherence technology (DAT) for tuberculosis (TB) treatment, specifically, the TB Treatment Support Tools (TB-TST) intervention, which integrates a mobile app designed to enhance patient-centred support, monitoring and communication, alongside a drug metabolite test.
Design:
Qualitative study conducted as part of a pragmatic randomised controlled trial.
Setting And Participants:
Four public reference hospitals in Argentina. All patients in the intervention group were invited to participate; 33 patients in the intervention group and five treatment supporters were included.
Data Collection And Analysis:
semistructured interviews were conducted. The normalisation process theory guided analysis to understand factors that enable or hinder the intervention's integration into routine practice for TB treatment medication adherence.
Results:
Patients identified medication reminders, educational messages and direct communication with treatment supporters (TSs) as the most helpful components of the intervention. Many reported using the app to ask TSs questions they felt uncomfortable raising with physicians in person. Initially, many patients did not fully understand the purpose and use of the metabolite test. Over time, their understanding of the app improved, though some continued to misinterpret the test results. Motivation to adhere to TB treatment was primarily driven by a desire to protect family members and resume normal daily activities. Reported barriers to app use included time constraints due to work, technical issues, limited internet connectivity and the burden of medication side effects. While the intervention was generally perceived as supportive and user-friendly, patients suggested improvements such as faster response times from TSs, expanded availability and better technical reliability and internet access.
Conclusion:
These findings highlight the importance of tailoring digital adherence interventions to meet the diverse needs of patients and reinforce the pivotal role of the TS as a trusted and accessible source of guidance throughout TB treatment.

The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
