The Validation Of COVID-19 Information In The Pharmacoepidemiological Research Database of Spain's Public Health System Data by Vaccination Status

Herein, we demonstrated that COVID-19 diagnoses in the Spanish public primary care records are truly associated with infection-positive tests, especially for patients >70 years old, and that most of the patients with positive tests also have a diagnosis of infection in primary care.

Description
Summary:Herein, we demonstrated that COVID-19 diagnoses in the Spanish public primary care records are truly associated with infection-positive tests, especially for patients >70 years old, and that most of the patients with positive tests also have a diagnosis of infection in primary care. [...]the Spanish data on COVID-19 is a valid research tool. To this extent, a clear example of the work performed in Spain is given by the Spanish Pharmacoepidemiological Research Database for Public Health System ( Base de datos para la Investigación Farmacoepidemiológica en el Ambito Público or BIF AP) database, a single integrated electronic health record (EHR) system, able to link and merge patient information from several Spanish regional data sources with different settings1. Since 2020, primary care EHRs directly gathered by BIFAP have been merged in a CDM with SARS-CoV-2 positive laboratory tests, and hospital and intensive care unit (ICU) admissions of external healthcare institutions. The pandemic data unification allowed the execution of different COVID-19 vaccination studies and the production of significant real-world data evidence during the last years2,3. [...]the EHR CDM creation has been crucial for studying and understanding COVID-19-related matters on the population, undoubtedly supporting important urgent national authorities' decisions about public health measures4,5,6 CO VID-19 information linked from different data sources may not always overlap and must be evaluated for identification of true cases for research. Methods Data sources and CO VID-19 information Patients' data from the Spanish public National Health System (SNS) data sources were linked and unified in BIFAP1 * Data about COVID-19 diagnosis, birth year, sex, and COVID-19 vaccination of around 13.7 million patients (7.4 million of them aged >18 years) were obtained from the public PC source for four geographical regions (Aragon, Asturias, Castilla y León, and Murcia).
