From the Air to Care: Drones and Their Expanding Role in Healthcare

21 May 2024


The initial pilotless vehicles, developed in Britain during World War I, were merely small radio-controlled aircraft with rudimentary capabilities. Since then, this technology has evolved into the sophisticated and autonomous Unmanned Aerial Vehicles (UAVs) that we now see in the skies. 

Within the category of UAVs, drones have emerged as a significant subset. Originally designed for military use, drones are now increasingly utilized for healthcare purposes, reflecting their expanding role beyond defense.  

In terms of value, the global UAV market with SATCOM capabilities accounted for $25.59 billion in 2018 and is expected to grow at a significant CAGR during the forecast period 2019-2029.

Advantages of Medical Drones in Healthcare 

Transporting materials to and from patients or medical facilities can be expensive, time-consuming, and often logistically complex. Deliveries, especially those that are time-sensitive, must be executed swiftly. However, traditional delivery methods depend on road traffic, which has its limitations in speed and reach.  

Consider a scenario where a patient in a critical condition urgently needs a blood transfusion but is situated in a remote rural area. In such cases, medical drones can provide a lifesaving solution by making timely deliveries possible.  

Here are several ways in which drones are revolutionizing healthcare delivery: 

1. Rapid Transport of Critical Supplies: Drones expedite the delivery of essential medical items, such as vaccines, medications, blood units, and even organs for transplantation, much faster than conventional methods. This rapid delivery is crucial in emergencies where time is of the essence. 

2. Enhanced Access to Remote Locations: Drones serve as a vital resource in rural or isolated areas that lack robust healthcare infrastructure. They can navigate difficult terrains to deliver crucial medical supplies, thereby enhancing healthcare accessibility. 

3. Reduction of Infection Risks: In global health emergencies, drones can transport medicines and collect samples while minimizing human contact, thus reducing the risks of spreading infections. 

4. Cost Efficiency: Over time, drones can reduce transportation costs, especially for delivering supplies short distances or to areas that are difficult to access, offering significant cost advantages.

Recent Case Studies 

1. The capabilities of drones are being recognized and utilized across the globe. For instance, in Rwanda, a venture called Zipline employs drones to distribute blood supplies to isolated regions. During the COVID-19 pandemic, China used drones to ferry medical supplies and patient samples, thereby minimizing the risk of cross-infection.  

2. Matternet, based in the USA and established in 2011, initially conducted flights between two hospitals in Lugano, Switzerland. Presently, they have partnered with UPS to deliver medical samples and are collaborating with VillageReach in Lilongwe, Malawi, to transport blood from remote areas to urban hospitals. 

3. Instadrone, a French startup established in 2014 and headquartered in France, is currently piloting the transportation of blood samples in Montpellier. This initiative is being carried out in collaboration with Inovie, a French laboratory group. 

4. RigiTech, established in 2018 and based in Switzerland, specializes in laboratory logistics. Their drones are operational in the Leman Lake region and across France, transporting various medical samples, including blood samples.  

Challenges of UAVs in Healthcare 

While drones have a smaller environmental impact than traditional vehicles like trucks, even electric ones, especially in delivering small items, challenges remain. Notably, recycling and reusing drone materials such as metals, fibers, and electronic components proves difficult. However, innovations like drones made from biodegradable mycelium, explored by students in a competition, show promise.  

Concerns about the liability and responsibility of medical drones are significant. As David Rovira notes, drones should be considered as vehicles and thus require insurance, leading to the development of specific drone insurance policies. Additionally, while most delivery drones are equipped with parachutes to reduce the risk of damage to contents like samples during emergency landings, the financial responsibility for any damage depends on the terms agreed upon in the contract between the laboratory and the drone operator, similar to traditional transportation agreements.  

Future of Medical drones 

Firstly, drones that exceed specific size and power thresholds—those flying "Beyond Visual Line of Sight" (BVLOS) and autonomous drones—must be registered with the relevant aviation authority for oversight purposes. 

As drones share airspace with other aircraft, they must adhere to aviation regulations. Currently, drone-specific regulations are either being drafted or adopted, beginning with the writing of Industrial Standards, which are industry-created with the aim of becoming law. 

Additionally, drone operators planning to fly a specific route must complete a Specific Operations Risk Assessment (SORA), which can take up to six months. This process involves detailing to the local Civil Aviation Authority how they will mitigate risks associated with their drone operations.  

Conclusion 

Drones present a compelling opportunity to improve healthcare delivery. As the healthcare sector constantly seeks innovative solutions, drone technology stands out as a promising method to expedite and expand the reach of medical services.  

By harnessing the capabilities of drones, healthcare providers can deliver critical supplies more swiftly, access remote areas more easily, and operate more efficiently, ultimately enhancing patient care and outcomes. This technology not only speeds up the transportation of essential medical resources but also broadens the scope of healthcare accessibility, ensuring services can be extended even to underserved or hard-to-reach populations.
