Disconnected data silos make it difficult to take a closer look at accidents and emergencies across multiple areas. The ISAN project aims to collect large amounts of data from various sources, such as emergency medicine (EMS), the electronic health record (EHR), and event data recorder (EDR), and to connect it by creating a technical basis. The ISAN system consists of an ID management center (generation and handling of ISA numbers as globally unique IDS), a trustee (data supplier), data consumers, and the data sources.

With the increase of IoT devices (Internet of Things) and sensor-based information systems in the immediate vicinity of people, such as smart homes, smart vehicles, and wearable computing, a large amount of data is being recorded and made available. The intelligent systems recognize undesired events and then trigger an alarm, the information supplied can be of crucial importance for the rescue service. The EMS (Information and Communication Technology) ICT systems collect rescue data, such as initial findings and continuous data from health monitoring during patient transport. Medical data is recorded in the hospitals and forms an EHR. Large amounts of data are created when the information from the various areas and systems is linked together.

In this project, we propose the networking of ICT systems in the emergency and rescue chain. This includes systems for generating emergency messages, as well as systems in the preclinical and the treatment process in the hospital. Our approach aims to make large amounts of data collected in accident and emergency systems immediately available. To this end, we will introduce an ISA number that prospectively and retrospectively supports rescue services and virtual registers for research. With this approach, the data remains on the local systems where it was recorded and is only linked using ISAN-based identifiers when required. In addition, we will evaluate our approach and the resulting benefits based on two use cases.
