ICMR i-DRONE Study: Drone-Enabled TB Sample Transport Cuts Diagnosis Time and Patient Costs in Remote Telangana

📌 Summary:

• ICMR's flagship i-DRONE initiative found that drone-enabled transport of TB sputum samples significantly improves diagnostic access in remote areas of Telangana
• Study run in Yadadri-Bhuvanagiri district with AIIMS Bibinagar and the District TB Office under the National TB Elimination Programme (NTEP); 840 participants enrolled
• Median turnaround time for TB diagnosis fell from 15 days to 5 days, enabling earlier confirmation and faster clinical decisions
• Mean out-of-pocket expenditure dropped from ~₹9,451 to ~₹91 (median zero) due to lower travel costs, reduced wage loss and nearby sputum collection
• Delivered via a hub-and-spoke network of 11 Primary Health Centres, 60 sub-centres and 4 TB Units
• Operational challenges flagged: weather, payload limits and continued training needs; evidence is from one district

🎯 UPSC Relevance: GS3 – technology applications in healthcare and diagnostics; GS2 – health governance and TB elimination

📝 Prelims Facts:

• i-DRONE = ICMR's drone-based delivery initiative (first piloted in the North East)
• NTEP = National TB Elimination Programme; India targets TB elimination
• Turnaround time 15→5 days; out-of-pocket cost ₹9,451→₹91

🔑 Key Term: Hub-and-spoke model – a network design routing samples from peripheral collection points (spokes) to a central diagnostic lab (hub)
