Drones Cut Tuberculosis Diagnosis Time from 15 to 5 Days in Telangana

A recent study by the Indian Council of Medical Research (ICMR) has revealed that using drones to transport sputum samples for tuberculosis (TB) diagnosis significantly reduces both the time required for diagnosis and the associated costs. Conducted within the framework of ICMR’s i-DRONE initiative, the study reported a median turnaround time for TB diagnosis decreasing from 15 days to just five days when drones were employed.

The initiative aims to improve healthcare access by bridging geographical barriers, particularly in remote areas of Telangana's Yadadri-Bhuvanagiri district. The comprehensive study involved 840 participants and assessed the impact of drone-enabled transport compared to conventional methods where patients had to travel to diagnostic centres.

One of the most significant findings from the study is the drastic reduction in out-of-pocket expenditure for patients seeking TB diagnoses. Costs plummeted from approximately ₹9,451 to only ₹91 due to lower travel expenses, reduced wage loss, and the convenience of having sputum collection facilities closer to patients' residences. Notably, during the drone-enabled phase, the median out-of-pocket expenditure was recorded as zero, indicating that many participants incurred no travel costs at all.

The ICMR noted that improving access to timely diagnoses is crucial in the fight against tuberculosis in India. Dr Rajiv Bahl, Secretary of the Department of Health Research and Director General of ICMR, commented that this study illustrates how technology can alleviate the burden on patients, particularly in underprivileged regions. "Affordable and timely access to diagnosis remains central to India’s TB elimination efforts," he stated.

The drone network established as part of this study connected 11 Primary Health Centres, 60 sub-centres, and four TB units. This network allowed patients to submit sputum samples at facilities closer to their villages, negating the need for long-distance travel.

Healthcare workers involved reported that the drone transport system improved operational efficiency and was accepted well by local communities, although they encountered some operational challenges, including weather conditions, limitations on payload capacities, and the requirement for ongoing training.

The study's findings, while promising, are based on implementation within a single district. ICMR officials have emphasised the need for further validation across various settings before widespread adoption within the National Tuberculosis Elimination Programme (NTEP). The i-DRONE initiative also aims to explore the use of drone transport for vaccines, medicines, and other medical supplies to enhance healthcare access in difficult terrains across India.

As healthcare systems evolve to meet the challenges presented by conditions such as tuberculosis, the integration of innovative solutions like drone transport could significantly enhance both efficiency and patient accessibility in future medical practices.
