Although emergency medical services are among the largest referrers to emergency departments, there are still only few large-scale systematic analyses of EMS patient characteristics. Since 2017, the web-based IVENA system has been used across Germany to digitally register EMS patients at acute care hospitals.

For every allocation, an anonymized dataset is created and stored, including variables such as age, sex, coded suspected diagnosis, urgency, assignment pathway, physician accompaniment, CPR, ventilation, infection status, pregnancy, and requested resources like resuscitation room or cath lab.

In early 2021, members of the DGINA working group in Hesse initiated this collaborative platform to merge IVENA allocation data from many hospitals and enable shared statistics and dedicated analyses for specific emergency care research questions.
