Catalonia is preparing to launch a air corridor for health workers using drones which, if the planned deadlines are met, will begin regular operations this summer. This service will connect the Pallars Regional Hospital, in Tremp (Lleida), with the Arnau de Vilanova University Hospital in Lleida, becoming the first stable corridor of its kind in the State.
The new system will allow transport blood bags, biological samples, medicines and small medical supplies between both centers, especially valuable for rural and mountain areas where road access can be slower or more complicated due to the weather. The Catalan government aims to shorten travel times, reduce emissions, and ensure more equitable access for people living far from major urban centers.
A pioneering health corridor between Tremp and Lleida
The journey between Tremp and Lleida is still made today by road in about 75 minutesFollowing a route of approximately 100 kilometers with mountainous sections. With the new corridor, the time will be reduced to between 40 and 50 minutes of flightAccording to the various technical estimates provided by the Government. In the most recent phases of the project, there is already talk of typical durations of 40-45 minutes, which represents a reduction of around half an hour compared to conventional transport.
During a demonstration at the Pallars Regional HospitalThe actual operation of the service was simulated: a nurse placed a refrigerator with blood samples in the drone's cargo compartment to send it to Lleida. This type of cargo includes blood components, other types of biological samples, drugs and medical supplies that need to arrive in good condition and in the shortest possible time.
The project is driven by the Department of the Presidency, through the Center for Telecommunications and Information Technologies (CTTI), and for the Ministry of Healththrough Fundació TIC Salut i SocialTheir stated goal is improve response times and territorial equity in access to certain health resources, especially in hard-to-reach areas with a dispersed population.
The choice of the Tremp-Lleida axis is not accidental. It is based on a study entitled "Integration of drones into the health system: key areas for territorial deployment", prepared by the TIC Salut i Social Foundation. This report identifies ten strategic zones and 15 hospitals of the Catalan public system where it would be viable to deploy short and medium term healthcare logistics routes using drones, including the health regions of Lleida SPAIN y High Pyrenees and Aran.
Fewer emissions and better sample preservation
Tests carried out by the Generalitat since 2023 show that The use of drones significantly reduces transport times facing the road. In two previous pilots, one in the Garrotxa and another in the Metropolitan North Health Region, a was verified reduction of more than 70% in journey timesThis supports the commitment to this technology in the healthcare sector.
But it's not just time that's saved. The shift to air transport has revealed a 98% reduction in COâ‚‚ emissions compared to conventional vehicles, aligning with greenhouse gas reduction targets. For the Government, this is a direct contribution to the fight against climate change without sacrificing the quality of care, but rather reinforcing it.
Improvements have also been observed on a strictly clinical level. In the Garrotxa test, a approximately 50% reduction in the degradation of blood samples, a phenomenon known as hemolysiswhich is favored by the rattling and vibrations of the road. In the tests carried out in the metropolitan area, the drone-transported samples arrived in optimal conditions, without being affected by the irregularities of the road surface.
These types of results have led those in charge of the project to emphasize that drones not only They accelerate logistics, but they can also improve the reliability of diagnosesby ensuring that samples arrive at laboratories in better condition. In environments where every minute counts, having access to higher quality samples can make a difference in clinical decision-making.
Furthermore, since it is a medium that It does not depend on the condition of the roads or traffic.The risks of delays due to traffic jams, roadworks, or weather incidents are minimized. The management of the Pallars Hospital has indicated that In winter, snowfall can close roads, a situation in which having an alternative air route is especially useful.
Authorizations, technical phases and daily operation
The Tremp-Lleida corridor has already completed a first phase of technical and security testingboth in the hospital setting and in flight. The project is currently under review by the State Aviation Safety Agency (AESA), from which it is expected to obtain a advanced authorization that allows to operate regular and autonomous flights with all guarantees of air safety.
Once AESA gives the green light, expected this summer, a service will be launched that will combine scheduled flights with unscheduled operations and on-demand requestsThis means that, in addition to regular shipments, specific flights can be activated in case of emergency, for example to transport critical samples, urgent medication, or blood components necessary for an intervention.
The drones used in the project are designed to transport loads of up to about four kilos in compartments adapted for medical supplies. They have a approximate autonomy of one hour, enough to cover the outbound journey with a safety margin. Healthcare staff have begun a training process to learn how Prepare the load, insert and remove the refrigerators and manage battery replacement when necessary.
The project managers also emphasize that it is a flexible technology with no time restrictionsIt can operate morning, noon, and night, and is prepared to fly even in adverse weather conditions within established safety limits. According to the Catalan Ministry of Health, this will allow Maintaining connectivity between centers even when weather conditions complicate road travel.
Daily operations will seek to integrate the use of drones into the typical hospital logistics flowsin coordination with ground transport. The aim is not to completely replace ambulances or medical delivery vehicles, but complement these resources and book flights for critical shipments or those where time or sample quality are especially relevant.
Connectivity for rural areas and network of future corridors
One of the central motivations of the project is to strengthen the healthcare connectivity in rural and mountain environmentsThe Minister of Health, Olga PaneHe has insisted that many of these territories have small centers, local clinics and an aging populationwhere access to certain resources is limited by distance and the characteristics of the road network.
From the management of Pallars Hospital, the doctor Palmira Borràs has described the initiative as a a very significant advance for the Alt PirineuIn his opinion, it will not only improve the daily logistics of samples and medicines, but will also contribute key support in urgent and emergency situationsespecially in hard-to-reach areas where drones could arrive before the healthcare staff themselves.
In this context, it is envisioned that drones may to provide support in the healthcare field making it arrive faster, for example, telemedicine devices or other equipment to assist dependent individuals or those with mobility issues. In geographically dispersed areas, this rapid response capability can help reduce inequalities in access to care.
The Secretary of Telecommunications and Digital Transformation, Albert TortHe emphasized that the Tremp-Lleida corridor will be one of the first of its kind in rural environments at the state level. The Generalitat's intention is to go beyond this first axis and weaving a network of air corridors that connect different health centers in the territory.
Parallel to the main route, the Alt Pirineu i Aran Sanitary Region is already studying the implementation of new corridors between Tremp, Sort and VielhaAccording to various documents and official statements, some reports mention that two new initial routes and others broaden the perspective to a greater number of potential connectionswhich would be deployed progressively based on demand and accumulated experience.
A scalable model for the health system
The report by the Fundació TIC Salut i Social that supports the project is not limited to the Pyrenees region. After analyzing the feasibility of integrating drones into the logistics of public hospitals in the Catalan system, several issues have been identified. ten strategic zones and fifteen centers where it is considered feasible to implement regular air ambulance routes in the next years.
Within this map, the health regions of Lleida and Alt Pirineu i Aran They are among the top candidates, precisely because of the combination of long distances, complex terrain and lower population densityHowever, the idea is that, once the service is consolidated in the Tremp-Lleida corridor and its extensions, the model can replicate and adapt to other territories, both in Catalonia and, potentially, in other autonomous communities or European countries.
According to the Government, the intention is to develop a "digital layer" of applications that allows for the integrated management of different transport options. In practice, this would translate into a system capable of automatically decide which is the best route and the most suitable means (drone or road) depending on the urgency, weather, load or the condition of the road network.
This medium-term vision also includes the gradual incorporation of machine vision and robot control tools to prioritize requests, organize flight plans, and optimize resources. In this way, the drone network would become another piece of the digital healthcare infrastructure, connected to the information systems of hospitals, primary care centers and other emergency services.
With the activation of these corridors, the Generalitat hopes that Catalonia consolidates itself as a benchmark case in Spain and Europe in the integration of logistics drones into healthcare services. The model is conceived as scalable and exportable to other contexts where similar challenges of geographical dispersion and the need to improve territorial equity exist.
Public-private collaboration and GovTech approach
The project is part of the strategy of digital transformation and public innovation of the Government, which seeks to apply technological solutions to complex administrative challenges. In this case, it is channeled through the program GovTech Catalunya, aimed at bringing the Administration closer to the technological and entrepreneurial ecosystem to develop projects with useful, governed, and results-oriented technology.
Several key stakeholders are involved in the initiative. Blood and Tissue Bank takes care of the validation of blood component transportensuring that all safety and conservation requirements are met. The company T-Systems Act like technology collaboratorWhile Pyrenees Drone assumes the role of flight operator, responsible for drone operations and compliance with aviation regulations.
From the Administration's perspective, this type of project is considered to help modernize public servicesmaking them more agile, efficient and tailored to the needs of the citizensHowever, the Generalitat insists that the implementation will be gradual, evaluating the safety, effectiveness and acceptance by professionals and patients at each stage.
The Catalan Minister of Health has described the use of drones as a "Positive technology at the service of people and healthcare", while the Secretariat of Telecommunications emphasizes the idea of leadership in responsible innovation applied to public services. Both departments agree that the key is not the technological innovation itself, but its real impact on the quality of care and on territorial cohesion.
With this air ambulance corridor, Catalonia opens the door to a new way of understanding logistics in healthcarewhere drones are integrated with traditional transport to better address the specific needs of the region. If the results confirm expectations in terms of time, cost, and quality of care, the model could serve as a reference for other healthcare systems seeking similar solutions to the challenges of rural depopulation and geographical dispersion.
