The NHIF of Hungary is a nationwide, longitudinal database of detailed healthcare service information for the entire population of Hungary (approximately 10 million people). All recorded healthcare events are linked to individual patients by a unique patient identifier (social security number), thereby allowing for longitudinal patient analysis. The database includes demographic data, such as date of birth, gender, and geographical region, for all patients. It also has financial claims information for all inpatient hospital stays and outpatient visits reimbursed by the insurance fund from 2009 to the present, along with drug dispensation information. Patient death information is also included along with the date of death of deceased patients.

Recruitment is ongoing
