ICMR study: Drone transport of TB samples reduces diagnosis time, patient costs in Telangana
UPSC / SSC current affairs note
Why in news
An ICMR study under the i-DRONE initiative demonstrates that drone-assisted transport of sputum samples significantly reduces TB diagnosis time and out-of-pocket expenditure for patients in remote areas of Telangana. This provides evidence for leveraging drone technology to strengthen healthcare access in underserved regions.
Background
India has a high burden of tuberculosis (TB) and aims to eliminate it by 2025 under the National TB Elimination Programme (NTEP). Remote areas often face delays in diagnosis due to poor transport infrastructure, leading to higher costs and disease progression. The i-DRONE initiative by ICMR explores drone-based logistics for health sample transport.
Key facts
The study was conducted in Yadadri-Bhuvanagiri district, Telangana, in collaboration with AIIMS Bibinagar and the district TB office under NTEP.
It compared traditional patient travel for TB diagnosis with a drone-based model where sputum samples were collected at PHCs/sub-centres and transported via drones to TB diagnostic labs.
840 participants were included; average diagnosis time reduced from 15 days (traditional) to 5 days (drone-based).
Average out-of-pocket expenditure (OOPE) dropped from ₹9,451 (traditional) to ₹91 (drone-based); median OOPE was zero in the drone phase.
The drone network connected 11 PHCs, 60 sub-centres, and 4 TB units in a hub-and-spoke model.
Health workers reported reduced delays, improved operational efficiency, and good community acceptance.
Operational challenges identified: weather, payload limits, and need for continuous training.
The study provides real-world evidence for drone logistics in geographically challenging areas.
