World TB Day: WHO updates guidelines, urges accountability
WHO fully released new treatment guidelines for multidrug-resistant tuberculosis, or MDR-TB, and announced a package of actions it said is designed to help countries close gaps in care.
The actions were taken ahead of World TB Day, observed each year on March 24.
“To win the fight against TB, multisectoral accountability, engagement and action is vital,” Tereza Kasaeva, MD, PhD, director of WHO’s Global TB Programme, told Infectious Disease News.
WHO previewed the new MDR-TB guidelines last year. They recommend shifting to a fully oral regimen.
According a news release, a “larger package of actions” meant to increase the progress toward ending TB was designed to help countries address gaps in care, “ensuring no one is left behind.”
WHO described the package as including:
- an accountability framework to coordinate actions across sectors and to monitor and review progress;
- a dashboard to help countries know more about their own epidemics through real-time monitoring — by moving to electronic TB surveillance systems;
- a guide for effective prioritization of planning and implementation of impactful TB interventions based on analyses of patient pathways in accessing care;
- ·new WHO guidelines on infection control and preventive treatment for latent TB infection;
- and a civil society task force to ensure effective and meaningful civil society engagement.
“The framework promotes the following key principles to accelerate progress to end TB: 1) All high-level commitments should be urgently translated into national targets with a comprehensive action plan; 2) Regular monitoring and reporting from all sectors should be enabled and ensured; 3) Comprehensive review of all actions of different stakeholders should be provided,” Kasaeva explained.
Additionally, electronic TB surveillance systems will help countries monitor TB cases in real time, allowing public health officials and other experts to learn more about TB epidemics occurring in their country.
“Infectious disease clinicians are a key provider of essential care to people with TB,” Kasaeva said. “Accountability for ID clinicians means providing high-quality care to all patients by ensuring early diagnosis and treatment according to WHO guidelines, adverse drug safety monitoring, mandatory notification and reporting.”
