Digital Health Intervention to Improve TPT Uptake

Plain-language summary

Despite the evidence of the prevention and control measures of tuberculosis (TB), it still has an impact on the health, social, and economic aspects of the population. Specifically, tuberculosis in children and newly diagnosed TB cases show there is current transmission of TB; to reduce this transmission and to attain the end TB strategy, preventing household TB transmission plays a great role. However, initiation and completion of TB preventive therapy (TPT) among close contacts of index TB patients are suboptimal. Some of the identified factors of low TPT initiation and completion are insufficient patient education, inadequate understanding of TPT, health professionals' perception, parental knowledge, and belief. The digital health intervention is currently being studied as a suggested health intervention that improves the utilization of health care services, including treatment adherence. A systematic review shows that TB treatment outcomes improved with the use of patient education, counseling, text reminders, and digital health technologies. However, other literature indicates controversial results, including our systematic review result, which identified that video directly observed therapy and text message (digital intervention) have no significant effect on TPT completion. In addition, the studies are scarce; therefore, this study aims to assess the effect of video-based education intervention combined with text message reminder (digital health intervention) in improving the initiation and completion of TPT among close contacts of drug-sensitive pulmonary TB patients in South Ethiopia. The study hypothesizes that digital health intervention for close contacts of index drug-sensitive pulmonary TB patients will lead to higher TPT initiation and completion rates than standard care.
