Preventing TB

Tuberculosis (TB) infection is extremely common: an estimated one-quarter of the world’s population is infected. People with TB infection risk developing TB disease and this risk depends on multiple factors, the most important being the state of their immune system.

TB preventive treatment stops TB infection from progressing to disease in those who are infected and can protect both the individual and the community from TB. WHO develops guidelines and operational handbooks to accelerate increased treatment coverage in countries. Tools such as the Prevent TB platform support national health systems to strengthen their strategic information.

In addition, WHO supports countries to prevent TB infections through guidance and implementation of infection prevention and control measures. These measures are critical in situations where the risk of TB transmission is high, such as health-care facilities, congregate settings and TB-affected households.

WHO also promotes preventive action through early screening and treatment for active TB, by addressing co-morbidities and health risks as well as social determinants of the disease, and by promoting access to universal health care.

Additionally, WHO advises and guides the TB vaccine development activities of the global research community through scientific consensus-building, guidance on vaccine evaluation, and assessment of the evidence base for policy recommendations.

Prevent TB Digital Platform

Prevent TB facilitates evaluation of TB contacts at both healthcare settings as well as at the community level. The system supports continuous monitoring of registered individuals across the continuum of care for tuberculosis screening and tuberculosis preventive treatment, capturing data from the initial identification of the target population, registration, clinical assessment, TB screening, testing for tuberculosis infection, and tuberculosis preventive treatment. The platform also generates alerts for service providers when any implementation gap is noted as well as comprehensive performance indicators to facilitate monitoring.

Prevent TB Smart Setup

The national programme/project coordinators can use the smart setup to create a new program to configure data variables to be captured at the stage of registration, service delivery and also create context specific alerts, and publish the same for own use of the application in local context. The platform also allows the upload of historic data on index cases and facilitates evaluation of contact, and the management of users and health facilities.

Prevent TB Application

The application has two different interfaces which cater to healthcare providers and registered patients respectively.

Healthcare provider module

Healthcare workers can use this module to register new individuals from target populations and capture details of tuberculosis screening, test results or referral for tuberculosis preventive treatment. The different sections on the interface enable users to monitor the progress of their clients through the cascade of care for tuberculosis screening and preventive treatment.

Client module

Individuals registered on the platform can use this module to access their own health records, service history, and self-report medication adherence and drug adverse events. Users can also communicate with healthcare providers or access relevant educational content.

Prevent TB Dashboard

The dashboard allows data visualization through interactive charts, maps, real-time alerts, and elaborate line-lists thereby assisting programme managers in monitoring and evaluation of implementation.
