Clinical research using LInked Bespoke studies and Electronic health Records
CALIBER is a unique research platform consisting of ‘research ready’ variables extracted from linked electronic health records (EHR) from primary care, coded hospital records, social deprivation information and cause-specific mortality data.
Led from the UCL Institute of Health Informatics and the Farr Institute of Health Informatics Research, London, CALIBER enables researchers to recreate the longitudinal journey of patients (‘from cradle to the grave’) through care pathways to study disease onset and progression. Our aim is to foster an open community developing methods and tools to accelerate replicable science across all clinical and scientific disciplines spanning the translational cycle (from drug discovery through to public health).
The resource consists of data encompassing more than 10 million adults with 400 million person-years of follow-up, disease and risk factor phenotyping algorithms, methods, tools and scripts, specialised infrastructure and training and support.
We are delighted to announce the winner of the CALIBER collaborative grand challenge is Dr Yoryos Lyratzopoulos from the UCL Epidemiology of Cancer Healthcare and Outcomes Group. Dr Lyratzopoulos and his team (Dr Annie Herbert and Dr Cristina Renzi (UCL Department of Behavioural Science and Health) and Prof Kathy Prichard-Jones (UCL Institute of Child Health)) will submit a full proposal for approval by the Clinical Practice Research Datalink (CPRD) Independent Scientific Advisory Committee to carry out research into the likelihood of cancer and serious non-neoplastic diseases among primary care consultees using linked CPRD data under the CALIBER programme of research.

CALIBER operates a collaboration-driven data sharing model and promotes the transparent and scalable use of EHR data for research. We work alongside academic, National Health Service and commercial partners to facilitate collaboration and use of CALIBER data, from development of research proposals through to release of data in the CALIBER data safe haven.

CALIBER has research ethics approval (09/H0810/16) and ECC approval (ECC 2-06(b)/2009 CALIBER dataset) and initial funding was provided by the Wellcome Trust (086091/Z/08/Z) and the National Institute for Health Research (RP-PG-0407- 10314).
At the intersection of clinical research and computer science, the Data Lab seeks to develop data-driven computational methods and tools for exploiting electronic health records for biomedical research.
By providing a complete picture of patients’ health care utilisation and deep longitudinal phenotyping, CALIBER has become a leading research platform for the understanding of health progression.
