WIG2 Institute Research Database

WIG2 (the Scientific Institute for Health Economics and Health System Research) has a research database of data on the healthcare use and resource consumption of about 4.5 million anonymous patients, insured under the Statutory Health Insurance in Germany. The data are representative with respect to age and gender distribution in Germany, allowing for longitudinal observation of these data from 2010 to 2019.

The WIG2 research database is anonymized to ensure that individual patients, health insurers, and healthcare providers cannot be identified retrospectively. Additional data protection measures in place ensure that no claims data will be transmitted, or analyses conducted, that narrow down results to individual health insurers, fewer than five insured individuals, individual regions smaller than federal states. The initial population to be analysed must include at least 100 insured patients.

The WIG2 research database contains information on the demographics of the insured (e.g., age, gender, residency by region) and on healthcare services and the associated costs of both outpatient and inpatient care, drug therapy, medical devices, and home health care.

All analyses on the WIG2 research database are performed exclusively by the WIG2 Institute. Data will not be transmitted to outside parties.
