Q. Discuss how drone technology is being leveraged to strengthen last-mile healthcare delivery in India, with reference to the National TB Elimination Programme. (15 marks, 250-350 words)

India carries roughly a quarter of the global TB burden [5], where remote terrain delays sputum transport and diagnosis. Drone-based logistics under ICMR's i-DRONE initiative is emerging as a practical last-mile fix, aiding the National TB Elimination Programme's goal of eliminating TB before the global 2030 target [3].

Evolution of drones in Indian health delivery - i-DRONE was launched by ICMR as a drone-based COVID-19 vaccine delivery model for hard-to-reach regions [4]. - Use-cases widened progressively to blood bags and corneal tissue transport, showing viability for time-sensitive biological payloads [6]. - Enabled by regulatory clearances for medical drone corridors and a hub-and-spoke lab network.

Application under NTEP - An ICMR study with AIIMS Bibinagar and NTEP in Yadadri-Bhuvanagiri district, Telangana, used drones to ferry sputum samples to molecular testing labs [1]. - Median diagnosis turnaround fell from 15 days to 5 days, cutting the window of untreated transmission [1]. - Mean patient out-of-pocket expenditure fell from ₹9,451 to ₹91 — over 99% [1].

Why it strengthens last-mile delivery - Social: protects poor and tribal patients from catastrophic health expenditure and repeated travel. - Administrative: complements mass screening under the 100-Day TB Elimination Campaign (from 7 December 2024, 347 high-burden districts), where detection is useless without fast confirmation [2]. - Scientific: reduces sample degradation in transit, improving diagnostic accuracy.

Constraints - Limited payload, weather sensitivity, airspace clearance, and dependence on hub-lab capacity restrict blind scaling.

Drone logistics converts NTEP's screening reach into timely, affordable diagnosis — technology closing the gap that infrastructure alone could not. Scaling the Telangana template to other hilly and forested high-burden districts, backed by trained ground handlers and stronger molecular lab hubs, would align the programme with the right to health under Article 21 and SDG 3.3 on ending the TB epidemic.
