UOC involved in creating smart routes to ensure all rural areas have access to healthcare

The equivalent to the 15-minute city in rural areas is the 45-minute territory. These are areas where the inhabitants can access everything they need for a good quality of life in 45 minutes, either on foot or by bicycle. Some 85% of Spain's territory is considered to be rural, with an average population density of 17.7 people per square kilometre. In this large and sparsely populated rural Spain, "it's estimated that 9% of municipalities don't meet the 45-minute criterion," said Cristian Castillo Gutiérrez, a member of the Faculty of Economics and Business at the Universitat Oberta de Catalunya (UOC) and a researcher in the Sustainability, Management and Transport (SUMAT) research group.

In order to make a basic service like primary healthcare more accessible to the rural population, Castillo led a study, involving researchers from the UOC, the Universitat Autònoma de Barcelona and the Universitat Politècnica de Valencia, which used algorithms to create efficient routes for vehicles providing medical care services. "This means that the population in these areas, which is mostly older people and with little access to public transport, doesn't have to travel to a medical centre," explained Castillo. In specific terms, the study uses routing algorithms, which design the most efficient routes according to parameters such as priorities, visit duration and journey distances. The algorithms created can be scaled and customized.

The results of the study have been published in open access in the journal Socio-Economic Planning Sciences. The article includes a simulation of routing in a rural province. This simulation was performed in Segovia, a province where 11.8% of the municipalities are located more than a 45-minute walk from a primary healthcare centre. "It's a simulation that can easily be transferred to any other part of Spain," said Castillo, who is an expert in integrated management, operations and logistics systems. He pointed out that "the knowledge in the study is available to any public administrations that want to use it". 

Empty Spain

Some 15.9% of Spain's population, or just over 7.5 million people, live in rural areas, according to figures from the Ministry of Agriculture, Fisheries and Food. The definition of rural areas covers municipalities with fewer than 30,000 inhabitants and a population density of less than 100 inhabitants per square kilometre. On a smaller scale, 4.45 million inhabitants are registered as living in municipalities with fewer than 5,000 inhabitants, and approximately half of them (2.2 million) live in towns and village with a population of under 2,000 inhabitants.

The major depopulation of these rural areas, compared to the large concentrations of population in the urban centres, helps explain "the enormous difficulties faced by the rural population in accessing all the public resources and services necessary to lead a decent life under equal conditions," according to the Ministry.

The UOC, committed to the rural world

Four of the seven authors of the study belong to the UOC, an institution with a strong commitment to the rural world, in order to reduce the gap between the countryside and the city, and the socio-economic, environmental and gender inequalities that it creates. As well as Castillo, the authors of this study working at the UOC are Eduard Josep Alvarez Palau and Marta Viu Roig, who are also researchers in the SUMAT group, and Anna Serena Latre, who has a Master's Degree in Data Science.

This research has received a proof of concept grant from the UOC eHealth Center and it contributes to UN Sustainable Development Goals 3 Good Health and Well-being, 10 Reduced Inequalities and 11 Sustainable Cities and Communities.

UOC R&I

The UOC's research and innovation (R&I) is helping overcome pressing challenges faced by global societies in the 21st century by studying interactions between technology and human & social sciences with a specific focus on the network society, e-learning and e-health.

Over 500 researchers and more than 50 research groups work in the UOC's seven faculties, its eLearning Research programme and its two research centres: the Internet Interdisciplinary Institute (IN3) and the eHealth Center (eHC).

The university also develops online learning innovations at its eLearning Innovation Center (eLinC), as well as UOC community entrepreneurship and knowledge transfer via the Hubbik platform.

Open knowledge and the goals of the United Nations 2030 Agenda for Sustainable Development serve as strategic pillars for the UOC's teaching, research and innovation. More information: research.uoc.edu.
