In what could be a gamechanger for emergency healthcare, drones are proving faster and in some cases, more reliable than ambulances when it comes to delivering life-saving medical supplies like blood. A recent study by the Indian Council of Medical Research (ICMR) highlights how this technology is stepping in when every second counts.A 15-Minute Lifeline Over 35 kmIn a pilot experiment conducted in 2023, a drone carried blood bags from GIMS Hospital in Greater Noida to Lady Hardinge Medical College in Delhi’s Connaught Place. It was a 35-kilometre journey completed in just 15 minutes. For comparison, a regular ambulance would have taken over an hour.Though the experiment was carried out last year, ICMR published its detailed findings in June 2024 in a report titled, Adopting Drone Technology for Blood Delivery: A Feasibility Study to Evaluate Its Efficiency and Sustainability. The conclusion? Drones are not just fast, but they’re also safe and efficient for delivering blood in emergencies.Why Blood Delivery by Drone Is So ComplexUsing drones for healthcare is not a new idea, vaccines and other supplies have been flown into remote areas before. But transporting blood is much more sensitive. Blood components like red blood cells, plasma, and platelets need strict temperature control and careful handling to maintain their quality. Unlike organs, which are transported in rare cases, blood has to be moved more frequently and reliably.The ICMR study showed that with proper temperature-controlled packaging and special gel packs, blood can be transported without damage.Drones used in the trial carried 4 to 6 blood bags and followed India's aviation safety guidelines. Importantly, no significant damage, like hemolysis was found in the blood after the flight. The quality of the transported blood remained safe, and any minor changes were similar to those seen in van transport.Drones vs. Ambulances: Why It MattersThis isn't the first time drones have proven their worth. A few months earlier, a drone in Haryana slashed delivery time for eye tissues by 70%, flying 38 km from Sonipat to Jhajjar in just 40 minutes, a road trip that usually takes over two hours.In cities like Delhi, drones have also been used to control mosquito-borne diseases. It’s clear that drones are quickly expanding their role from novelty to necessity.But the ICMR also notes: more scientific evidence is needed before drones can be widely adopted for medical deliveries. The idea may be promising, but it’s not without its hurdles.What Are The Challenges AheadEven though the results are encouraging, many challenges remain. Regulatory restrictions, weather conditions, battery limitations, safety concerns, and costs are big roadblocks. Drones must also be seamlessly integrated into existing healthcare and air traffic systems.Blood transport, in particular, requires vibration validation, consistent temperature control, and real-time monitoring; any lapse could lead to damage or contamination.A pan-India regulatory framework is essential for scaling up. India’s vast and varied landscape, from mountains to dense urban centres presents its own set of complications. As a 2025 Journal of Transport and Public Health study pointed out, poor rural blood bank infrastructure and high costs could limit scalability.A Global TrendIndia isn’t alone in this journey. Rwanda was the first to adopt a national drone medical delivery system back in 2016. The UK also plans to launch nationwide drone medical deliveries by 2026 after successful NHS trials.India has already taken steps in this direction. Under the i-DRONE initiative launched in 2021, ICMR carried out successful drone-based deliveries of vaccines and medical kits in the Northeast. Now, the focus is shifting to more critical and sensitive deliveries like blood.
