[AKTIN - The German Emergency Department Data Registry - real-time data from emergency medicine : Implementation and first results from 15 emergency departments with focus on Federal Joint Committee's guidelines on acuity assessment]. / Das AKTIN-Notaufnahmeregister ­ kontinuierlich aktuelle Daten aus der Akutmedizin : Ergebnisse des Registeraufbaus und erste Datenauswertungen aus 15 Notaufnahmen unter besonderer Berücksichtigung der Vorgaben des Gemeinsamen Bundesausschusses zur Ersteinschätzung.

BACKGROUND: Emergency care in Germany is in transition. Emergency departments (EDs) treat their patients based on symptoms and acuity. However, this perspective is not reflected in claims data. The aim of the AKTIN project was to establish an Emergency Department Data Registry as a data privacy-compliant infrastructure for the use of routine medical data. METHODS: Data from the respective documentation systems are continuously transmitted to local data warehouses using a standardized interface. They are available for several applications such as internal reports but also multicentre studies, in compliance with data privacy regulations. Based on a 12-months period we evaluate the population with focus on acuity assessment (triage) and vital parameters in combination with presenting complaints. RESULTS: For the period April 2018 to March 2019, 436,149 cases from 15 EDs were available. A triage level is documented in 86.0% of cases, and 70.5% were triaged within 10 min of arrival. Ten EDs collected a presenting complaint regularly (82.3%). The respective documentation of vital signs shows plausible patterns. CONCLUSIONS: The AKTIN registry provides an almost real-time insight into German EDs, regardless of the primary documentation system and health insurance claims data. The Federal Joint Committee's requirements are largely met. Standardized presenting complaints allow for symptom-based analyses as well as health surveillance.

Secure Electronical Communications and Data Transfers in a Clinical Environment.

As part of the German Project AKTIN, data security arises as an important issue. The context of this issue was detailed and the requirements were determined, with special focus on the hospital's point of view. The solution is illustrated in this poster. Further use cases in other medical or study context are also discussed.

Periodic changes in blood flow in the in vivo rat kidney.

The frequency response of the blood flow through the rat kidney in vivo has been studied. A piston controlled by a random-signal generator compressed the abdominal aorta proximal to the renal artery eliciting stochastical arterial pressure changes of an amplitude of less than or equal to 5 mm Hg. This small amplitude allowed to study the system under physiological conditions. In accord with earlier results from isolated kidneys pressure induced maxima of flow resistance were found at 0.005 Hz and at 0.1 Hz, thus demonstrating that in vivo humoral and/or nervous factors do not significantly alter the renal vascular response to changes of arterial pressure.
