Únicas: Caring for rare diseases

‘Únicas’ is the name given to a range of transformative projects in the field of rare diseases, all of which are rooted in collaboration.

Únicas was founded in response to the need to support the large number of patients with rare or undiagnosed conditions. Rare diseases are conditions that affect fewer than 5 people per 10,000 inhabitants, but collectively affect millions of patients worldwide. According to data from Orphanet and the Spanish Federation for Rare Diseases (FEDER), there are more than 7,000 such conditions, the majority of which are genetic in origin (80%), and in 75% of cases, symptoms appear in childhood, making them a priority public health issue. Globally, they affect around 400 million people, of whom approximately 3 million live in Spain.

Diagnosis remains one of the major challenges: despite advances in genomic medicine and mass sequencing technology, nearly 50% of patients are unable to get a definitive diagnosis. This delay, which can vary between 4 and 10 years, has a significant impact on the quality of life of those affected and their families, who face uncertainty and limited access to treatment.

Furthermore, 95% of rare diseases lack a specific treatment, which highlights the urgent need to promote more efficient research and care strategies.

Únicas SJD: the hospital’s transformative strategy

In recent years, SJD Barcelona Children's Hospital —the hospital with the most pediatric care activity in the field of rare diseases in Spain and one of the largest in Europe— has developed a care model to address the growing challenges that these conditions pose on a daily basis for patients, families and the healthcare system as a whole.

With this in mind, a significant effort has been made to achieve excellence by obtaining accreditations on European, national and regional levels.

La Casa de Sofía was opened in 2022 – the first intermediate care center for pediatric patients with rare diseases and complex chronic conditions.

Determined to continue making progress towards establishing ourselves as a center of excellence in the field of rare diseases, the Hospital has been developing the ‘Únicas’ strategy since 2024. It involves a portfolio of transformative projects aimed at ensuring patients receive comprehensive, integrated and highly accessible care, incorporating telemedicine and digital transformation tools. It focuses on reducing the time taken to reach a diagnosis and on facilitating access to advanced and emerging therapies that can improve the quality of life of patients and their families.

Objectives of Únicas SJD

  • To implement a comprehensive and integrated healthcare model across the region.
  • To increase the provision of remote care to improve accessibility.
  • To expand the use of telemonitoring for patients with rare diseases.
  • To increase the diagnosis rate and reduce waiting times.
  • To develop, produce and administer new, advanced and emerging therapies.
  • Use data and artificial intelligence to drive forward diagnostics and new therapies.
  • Ensure that the development of the established objectives addresses the real needs of patients and their families, through their direct involvement or by incorporating their views from the design, development and evaluation stages onwards.

Únicas SJD’s Strategy: transversal projects

To draw more attention to rare diseases, the SJD Barcelona Children's Hospital aims to raise awareness of patients with rare and undiagnosed conditions by organising various events under the ‘Únicas’ umbrella, such as ‘Únicas Talks’ and ‘Únicas Hackathon’.

Únicas Talks

The SJD Barcelona Children's Hospital and the 'la Caixa' Foundation are joining forces to create a unique forum for dissemination and debate – the Únicas Talks seminars – to discuss the latest advances, perspectives and trends in patient-centered clinical management, as well as progress in the diagnosis and development of treatments for rare diseases.

Únicas Hackathon

The Únicas Hackathon is the first Ibero-American event of its kind, bringing together 140 specialists from 62 institutions across 14 different countries to tackle the challenge of arriving at the highest number of diagnoses from a selection of 12 cases. Following extensive preparation, experts in medical genetics, clinical laboratory genetics, bioinformatics, data science and other related fields worked intensively for 48 hours, fostering direct collaboration amongst themselves.

This inaugural edition took place in Murcia on 6 and 7 October 2025.

Leadership and management team

  • Encarna Guillén Navarro, Head of the Genetics Department and Strategic Director at Únicas SJD
  • Carmen Santamaria Guasch, Management Director at Únicas SJD

Únicas SJD Building – Center for Precision Medicine

Únicas also represents the Center for Precision Medicine at SJD Barcelona Children's Hospital. This facility, situated 200 meters from the hospital, will bring together the most advanced research, diagnostic and treatment facilities and will be equipped with the most innovative technology. The Únicas Building will be one of the three largest centers of its kind in the world and will continue to care for the more than 30,000 children and adolescents suffering from rare diseases across all of the Spanish autonomous communities, with the aim of advancing diagnosis and treatment.

Únicas Network Spain – Ministry of Health

Únicas also represents other major projects that are driving progress in the healthcare model, diagnostics and the treatment of rare diseases.

In 2022, with funding from the Carlos III Institute, Impact3 was founded – a project whose main objective is to connect a network of six Spanish hospitals to create a federated database containing clinical and genomic information, to be used with analytical tools that will speed up diagnosis across the country.

Following on from this initial project, in 2023 the Únicas Network was created, spearheaded by the SJD Barcelona Children's Hospital and the Spanish Federation for Rare Diseases (FEDER), led by the Ministry of Health and funded by Next Generation funds under the cutting-edge health PERTE program. Its aim is to create an ecosystem of partnerships — currently comprising 30 hospitals — to provide a coordinated response to patients with rare diseases throughout their entire healthcare journey.

The network’s first milestone is the creation of a data platform for patients with rare diseases across Spain, enabling progress towards a network-based model of personalised care.

Objectives of the Únicas Network

  • Let the data travel, not the patients: To treat pediatric patients with rare diseases at any node within the Únicas network as if they were at the center of excellence for their condition, regardless of where they live.
  • Network-Based Personalised Care Model: To implement, across all nodes of the Únicas network, the common tools, processes and protocols that enable a new network-based model.
  • To complement the current CSUR network in areas such as the patient’s perspective and the care provided by non-CSUR professionals:
    • Únicas 360: focused on healthcare professionals and on enabling them to share information with one another.
    • Únicas Channel: focused on the patient and the needs of families and carers.
  • To provide a holistic, longitudinal view of the patient throughout the entire care process.
