ICMR drone project reduces TB diagnosis time, eases patient burden
New Delhi, July 16
The Indian Council of Medical Research's flagship i-DRONE initiative demonstrated that drone‑assisted transport of TB sputum samples improved access to diagnostic services for people living in remote and underserved areas in the Yadadri‑Bhuvanagiri district, Telangana, the government said on Thursday.
The program enrolled 840 participants and found that the median turnaround time for TB diagnosis decreased from 15 days to 5 days following the introduction of drone-based sample transport, an official statement said.
Diagnostic delays were also significantly reduced, enabling earlier confirmation of disease and facilitating faster clinical decision-making.
The study compared the conventional system of patient travel for TB diagnosis with a drone-enabled model in which sputum samples were collected at nearby Primary Health Centres (PHCs) and sub-centres (SCs) and transported by drones to designated TB diagnostic laboratories (TUs), the statement from Ministry of Health and Family Welfare said.
The mean out‑of‑pocket expenditure for patients dropped from about Rs 9,451 to Rs 91. The intervention reduced travel costs and wage loss by enabling local sputum collection. Notably, the median OOPE during the drone phase was zero, indicating that many participants incurred no travel-related expenses for diagnosis.
The intervention was implemented through a hub-and-spoke network connecting 11 Primary Health Centres, 60 sub-centres and four TB Units, allowing patients to submit sputum samples at health facilities nearer to their villages instead of travelling long distances to diagnostic centres.
"Affordable and timely access to diagnosis remains central to India's TB elimination efforts. This study demonstrates how technology can help bridge geographical barriers and reduce the burden on patients, particularly those living in remote areas," said Dr. Rajiv Bahl, Secretary, Department of Health Research and Director General, ICMR.
The evidence generated through the i-DRONE initiative will inform future public health innovations while complementing existing healthcare delivery systems, he added.
Healthcare workers reported that drone-enabled transport reduced delays, improved operational efficiency and was well accepted by communities after initial familiarisation.
The study also identified operational considerations such as weather, payload limitations and the need for continued training, underscoring the importance of careful planning for wider implementation.

Impressive cost savings — from Rs 9,451 to just Rs 91! That's a 99% reduction in out-of-pocket expenses. In a country where even small medical costs push families into debt, this is a game-changer. I hope this model is scaled to other districts and other diseases too. Well done!
This is a great initiative, but we need to be practical. Drones can't fly in rain or strong winds, which limits their use in monsoon seasons. Also, with only 4 TB units connected, the coverage is still limited. Let's not get carried away — the real challenge is ensuring continuous funding and maintenance. Still, a step in the right direction!
The hub-and-spoke model is clever — it creates a network effect without needing a drone at every village. The fact that median out-of-pocket costs went to zero for many patients is remarkable. TB elimination is a national priority, and this kind of innovation is exactly what we need. Hope to see similar projects for malaria and leprosy!
"Tech can bridge geographical barriers" — exactly, Dr Bahl! India has so many hilly terrains and islands where roads are poor or non-existent. Drones could be a lifeline for these communities. But we also need to address the lack of awareness — many villagers still don't know about free TB testing at PHCs. Let's combine tech with better community outreach. 👍
The healthcare workers deserve special mention here! They not only collected samples but
