Drones reduce time and cost of TB diagnosis: Study, Pg13

Key Highlights:

• A study by the Indian Council of Medical Research (ICMR) in Telangana found that drones significantly reduced the time and cost of tuberculosis diagnosis.
• The average time for a TB diagnosis decreased from 16.6 days to 6.9 days using drones.
• The cost for diagnosis was drastically cut from ₹9,451 to just ₹91.
• This initiative, part of ICMR's i-DRONE initiative, aims to improve healthcare access in remote areas.
• India missed its self-imposed deadline of eliminating TB by 2025, while the global target is 2030.

Detailed Insights:

• The study implemented a hub-and-spoke model across 60 sub-centres, 11 Primary Health Centres, and four TB units in Telangana to transport patient samples.
• This approach addressed challenges like poor road infrastructure, unpredictable weather, and long distances that previously hampered timely diagnosis in remote regions.
• Patients, often from low-income backgrounds, previously faced travel difficulties, loss of daily wages, and stigma, leading to delays in seeking care.
• With drones, patients could submit sputum samples at nearby sub-centres or PHCs, which were then transported to molecular diagnostic facilities.
• The proportion of patients receiving diagnostic results within two days sharply increased, with next-day results rising from 1.5% to 76.3%.
• Delays exceeding two days fell significantly from 92.2% in the pre-drone phase to 16.3% in the drone-enabled phase.
• The i-DRONE initiative was initially launched during the COVID-19 pandemic to deliver vaccines and medical supplies in the Northeast and is now expanding its scope.
• India's National Tuberculosis Elimination Programme (NTEP), formerly the Revised National Tuberculosis Control Programme (RNTCP), aims to reduce TB incidence by 80% and mortality by 90% by 2025.

Key Concepts Involved:

• Tuberculosis (TB): A serious infectious disease primarily affecting the lungs, caused by the bacterium Mycobacterium tuberculosis, curable with proper treatment.
• i-DRONE initiative: An ICMR program utilizing drones for the rapid and efficient transport of medical supplies, vaccines, and diagnostic samples, especially in challenging terrains.
• National Tuberculosis Elimination Programme (NTEP): The flagship public health initiative of the Government of India, aiming to eliminate TB from the country by 2025.
• Hub-and-Spoke Model: A logistical and organizational structure where a central facility (hub) provides specialized services and coordinates with smaller, peripheral units (spokes) for wider reach.
• Molecular Diagnostics: Advanced laboratory techniques that detect specific genetic material of pathogens, enabling rapid and accurate identification of diseases like TB.
