The Andalusian Public Healthcare System has adopted the Andalusian Health Population Database as a corporate information system. This database is a population-based Health Information System since it allows data to be collected from every individual that is part of Andalusian population (those included in the User Database of the Andalusian Public Health System). The core of the information is provided by User Database and is complemented by diagnostic information and the use of health resources from the different primary and specialized care areas. Among the administrative-clinical sources, the digital medical history of Primary Care and the hospital Minimum Basic Data Set - MBDS (hospitalization, medical and surgical day hospitals and emergencies) stand out. The use of resources, measured in different units and valued in euros, includes Primary Care and the different processes of hospital care and the consumption of pharmacy, dialysis sessions and medical transport.
Data from 13 million people who have been users between 2001 and 2019 are included, with 435.5 million diagnoses. 88.7% of these diagnoses were generated by the automatic encoder. The data is presented through predefined reports or dynamic queries, both exportable to CSV files for treatment outside.
The practice is “on the market” and integrated in routine use. There is proven market impact, in terms of job creation, spin-off creation or other company growth. The system is currently in use, being the source of information to evaluate the performance of health centers. It is also used as a source of information in various research projects. Although the project is not new from a technological perspective, it represents an important advance in data governance in a regional health service. It will allow to face the challenges and limitations of Big Data.
