Primary and secondary data in emergency medicine health services research - a comparative analysis in a regional research network on multimorbid patients.

Background: This analysis addresses the characteristics of two emergency department (ED) patient populations defined by three model diseases (hip fractures, respiratory, and cardiac symptoms) making use of survey (primary) and routine (secondary) data from hospital information systems (HIS). Our aims were to identify potential systematic inconsistencies between both data samples and implications of their use for future ED-based health services research.

Methods: The research network EMANET prospectively collected primary data (n=1442) from 2017-2019 and routine data from 2016 (n=9329) of eight EDs in a major German city.

The Abdominal Pain Unit (APU). Study protocol of a standardized and structured care pathway for patients with atraumatic abdominal pain in the emergency department: A stepped wedged cluster randomized controlled trial.

This study aims to improve emergency department (ED) care for patients suffering from atraumatic abdominal pain. An application-supported pathway for the ED will be implemented, which supports quick, evidence-based, and standardized diagnosis and treatment steps for patients with atraumatic abdominal pain at the ED. A mixed-methods multicentre cluster randomized controlled stepped wedge trial design will be applied.

Cost-effectiveness of noninvasive telemedical interventional management in patients with heart failure: health economic analysis of the TIM-HF2 trial.

Background: Noninvasive remote patient management (RPM) in patients with heart failure (HF) has been shown to reduce the days lost due to unplanned cardiovascular hospital admissions and all-cause mortality in the Telemedical Interventional Management in Heart Failure II trial (TIM-HF2). The health economic implications of these findings are the focus of the present analyses from the payer perspective.

Methods And Results: A total of 1538 participants of the TIM-HF2 randomized controlled trial were assigned to the RPM and Usual Care group.

Lifestyle Intervention in Chronic Ischaemic Heart Disease and Type 2 Diabetes (the LeIKD study): study protocol of a prospective, multicentre, randomised, controlled trial.

Introduction: Guidelines recommend lifestyle intervention in chronic ischaemic heart disease (CIHD) and type 2 diabetes mellitus (T2DM). However, evidence from randomised controlled trials is scarce in patients with combined entities.

Methods And Analysis: The Lifestyle Intervention in Chronic Ischaemic Heart Disease and Type 2 Diabetes (LeIKD) trial is a prospective, multicentre study that will randomise (1:1) patients with CIHD (ICD-10: I20-I25) and T2DM (ICD-10: E11) from one health insurance company into a lifestyle intervention (LS) or usual care (UC).
