German Cardiac Arrest Registry (G-CAR)-results of the pilot phase.

BACKGROUND: In Europe, more than 300,000 persons per year experience out-of-hospital cardiac arrest (OHCA). Despite medical progress, only few patients survive with good neurological outcome. For many issues, evidence from randomized trials is scarce. OHCA often occurs for cardiac causes. Therefore, we established the national, prospective, multicentre German Cardiac Arrest Registry (G-CAR). Herein, we describe the first results of the pilot phase. RESULTS: Over a period of 16 months, 15 centres included 559 consecutive OHCA patients aged ≥ 18 years. The median age of the patients was 66 years (interquartile range 57;75). Layperson resuscitation was performed in 60.5% of all OHCA cases which were not observed by emergency medical services. The initial rhythm was shockable in 46.4%, and 29.1% of patients had ongoing CPR on hospital admission. Main presumed causes of OHCA were acute coronary syndromes (ACS) and/or cardiogenic shock in 54.8%, with ST-elevation myocardial infarction being the most common aetiology (34.6%). In total, 62.9% of the patients underwent coronary angiography; percutaneous coronary intervention (PCI) was performed in 61.4%. Targeted temperature management was performed in 44.5%. Overall in-hospital mortality was 70.5%, with anoxic brain damage being the main presumed cause of death (38.8%). Extracorporeal cardiopulmonary resuscitation (eCPR) was performed in 11.0%. In these patients, the in-hospital mortality rate was 85.2%. CONCLUSIONS: G-CAR is a multicentre German registry for adult OHCA patients with a focus on cardiac and interventional treatment aspects. The results of the 16-month pilot phase are shown herein. In parallel with further analyses, scaling up of G-CAR to a national level is envisaged. Trial registration ClinicalTrials.gov identifier: NCT05142124.

[Clinical acute and emergency medicine curriculum-focus on internal medicine : Recommendations for advanced training in internal medicine in the emergency department]. / Curriculum Klinische Akut- und Notfallmedizin ­ Schwerpunkt Innere Medizin : Empfehlung zu Weiterbildungsinhalten der Inneren Medizin in der Notaufnahme.

In Germany, physicians qualify for emergency medicine by combining a specialty medical training-e.g. internal medicine-with advanced training in emergency medicine according to the statutes of the State Chambers of Physicians largely based upon the Guideline Regulations on Specialty Training of the German Medical Association. Internal medicine and their associated subspecialities represent an important column of emergency medicine. For the internal medicine aspects of emergency medicine, this curriculum presents an overview of knowledge, skills (competence levels I-III) as well as behaviours and attitudes allowing for the best treatment of patients. These include general aspects (structure and process quality, primary diagnostics and therapy as well as indication for subsequent treatment; resuscitation room management; diagnostics and monitoring; general therapeutic measures; hygiene measures; and pharmacotherapy) and also specific aspects concerning angiology, endocrinology, diabetology and metabolism, gastroenterology, geriatric medicine, hematology and oncology, infectiology, cardiology, nephrology, palliative care, pneumology, rheumatology and toxicology. Publications focussing on contents of advanced training are quoted in order to support this concept. The curriculum has primarily been written for internists for their advanced emergency training, but it may generally show practising emergency physicians the broad spectrum of internal medicine diseases or comorbidities presented by patients attending the emergency department.

Ultrasound during Advanced Life Support-Help or Harm?

Ultrasound is used in cardiopulmonary resuscitation (CPR) and advanced life support (ALS). However, there is divergence between the recommendations of many emergency and critical care societies who support its use and the recommendations of many international resuscitation organizations who either recommend against its use or recommend it only in limited circumstances. Ultrasound offers potential benefits of detecting reversable causes of cardiac arrest, allowing specific interventions. However, it also risks interfering with ALS protocols and increasing unhelpful interventions. As with many interventions in ALS, the evidence base for ultrasound use is weak, and well-designed randomized trials are needed. This paper reviews the current theory and evidence for harms and benefits.

[Role of German cardiac arrest centers in mediating basic life support]. / Rolle deutscher Cardiac Arrest Center in der Vermittlung von Basisreanimationsmaßnahmen.

BACKGROUND AND OBJECTIVE: Despite a measurable increase in recent years, the bystander resuscitation rate in Germany lags behind the European comparison. Special centers for the care of patients after cardiac arrest, so-called cardiac arrest centers (CAC), have been established. The aim of this work is to evaluate the role of CACs, in addition to in-hospital patient care, in improving the bystander resuscitation rate in Germany and what obstacles exist in the implementation of resuscitation training. MATERIALS AND METHODS: Online survey by the working group cardiopulmonary resuscitation (AG42) of the German Society of Cardiology (DGK) and the German Resuscitation Council (GRC) RESULTS: Of the 74 participating clinics (78.4% certified as CAC), 23 (31.1%) conduct lay resuscitation training. These mainly take place within the framework of action days for resuscitation (82.6%) or in schools (39.1%). Permanent cooperation with at least one school existed in 52.2%. Basic life support (BLS) resuscitation dummies are available in 63.5% of these clinics and an automated external defibrillator (AED) demonstration device in 43.2%. According to the interviewees, the biggest obstacles to the consistent implementation of resuscitation courses in schools include lack of qualified instructors, lack of refinancing and difficulties with regard to coordinating activities between schools and providers. CONCLUSIONS: Direct training of lay rescuers by hospitals faces several obstacles. To increase the bystander resuscitation rate, focusing on targeted training of teachers as multipliers (train-the-trainer) can be a good approach for cardiac arrest centers.

Optic Nerve Sheath Diameter for Assessing Prognosis after Out-of-Hospital Cardiac Arrest.

PURPOSE: Evaluate optic nerve sheath and pial diameters (ONSD, ONPD) via sonography and computed tomography (CT) after out-of-hospital cardiac arrest (CA) and to compare their prognostic significance with other imaging and laboratory biomarkers. MATERIALS AND METHODS: A prospective observational study enrolling patients after successful resuscitation between December 2017 and August 2021. ONSD and ONPD were measured with sonography. Additionally, ONSD, and also grey-to-white ratio at basal ganglia (GWRBG) and cerebrum (GWRCBR), were assessed using CT. Lactate and neuron specific enolase (NSE) blood levels were measured. RESULTS: Sonographically measured ONSD and ONPD yielded no significant difference between survival and non-survival (p values ≥0.4). Meanwhile, CT assessed ONSD, GWRBG, GWRCBR, and NSE levels significantly differed regarding both, survival (p values ≤0.005) and neurological outcome groups (p values ≤0.04). For survival prognosis, GWRBG, GWRCBR, and NSE levels appeared as excellent predictors; in predicting a good neurological outcome, NSE had the highest accuracy. CONCLUSIONS: CT diagnostics, in particular GWRBG and GWRCBR, as well as NSE as laboratory biomarker, appear as excellent outcome predictors. Meanwhile, our data lead us to recommend caution in utilizing sonography assessed ONSD and ONPD for prognostic decision-making post-CA.

Oral anticoagulation in heart failure complicated by atrial fibrillation: A nationwide routine data study.

BACKGROUND: This nationwide routine data analysis evaluates if oral anticoagulant (OAC) use in patients with heart failure (HF) and atrial fibrillation (AF) leads to a lower mortality and reduced readmission rate. Superiority of new oral anticoagulants (NOACs), compared to vitamin K antagonists (VKA), was analyzed for these endpoints. METHODS: Anonymous data of patients with a health insurance at the Allgemeine Ortskrankenkasse and a claims record for hospitalization with the main diagnosis of HF and secondary diagnosis of AF (2017-2019) were included. A hospital stay in the previous year was an exclusion criterion. Mortality and readmission for all-cause and stroke/intracranial bleeding (ICB) were analyzed 91-365 days after the index hospitalization. Kaplan-Meier survival curves and multivariable Cox regression models were used to evaluate the impact of medication on outcome. RESULTS: 180,316 cases were included [81 years (IQR 76-86), 55.6% female, CHA2DS2-VASc score ≥ 2 (96.81%)]. In 80.6%, OACs were prescribed (VKA: 21.7%; direct factor Xa inhibitors (FXaI): 60.0%; direct thrombin inhibitors (DTI): 3.4%; with multiple prescriptions per patient included). Mortality rate was 19.1%, readmission rate was 29.9% and stroke/ICB occurred in 1.9%. Risk of death was lower with any OAC (HR 0.77, 95% CI [0.75-0.79]) but without significant differences in OAC type (VKA: HR 0.73, [0.71-0.76]; FXaI: HR 0.77, [0.75-0.78]; DTI: HR 0.71, [0.66-0.77]). The total readmission rate (HR 0.97, [0.94 to 0.99]) and readmission for stroke/ICB (HR 0.71, [0.65-0.77]) was lower with OAC. CONCLUSIONS: Nationwide data confirm a reduction in mortality and readmission rate in HF-AF patients taking OACs, without NOAC superiority.

[Monitoring of emergency cardiovascular patients in the emergency department : Consensus paper of the DGK, DGINA and DGIIN]. / Monitoring kardiovaskulärer Notfallpatienten in der Notaufnahme : Konsensuspapier der DGK, DGINA und DGIIN.

Patients with potential or proven cardiovascular diseases represent a relevant proportion of the total spectrum in the emergency department. Their monitoring for cardiovascular surveillance until the diagnostics and acute treatment are initiated, often poses an interdisciplinary and interprofessional challenge, because resources are limited, nevertheless a high level of patient safety has to be ensured and the correct procedure has a major prognostic significance. This consensus paper provides an overview of the practical implementation, the modalities of monitoring and the application in a selection of cardiovascular diagnoses. The article provides specific comments on the clinical presentations of acute coronary syndrome, acute heart failure, cardiogenic shock, hypertensive emergency events, syncope, acute pulmonary embolism and cardiac arrhythmia. The level of evidence is generally low as no randomized trials are available on this topic. The recommendations are intended to supplement or establish local standards and to assist all physicians, nursing personnel and the patients to be treated in making decisions about monitoring in the emergency department.

Recommendations on palliative care aspects in intensive care medicine.

BACKGROUND: The timely integration of palliative care is important for patients suffering from various advanced diseases with limited prognosis. While a German S-3-guideline on palliative care exists for patients with incurable cancer, a recommendation for non-oncological patients and especially for integration of palliative care into intensive care medicine is missing to date. METHOD: Ten German medical societies worked on recommendations on palliative care aspects in intensive care in a consensus process from 2018 to 2023. RESULTS: Based on the german consensus paper, the palliative care aspects of the respective medical disciplines concerning intensive care are addressed. The recommendations partly refer to general situations, but also to specific aspects or diseases, such as geriatric issues, heart or lung diseases, encephalopathies and delirium, terminal renal diseases, oncological diseases and palliative emergencies in intensive care medicine. Measures such as non-invasive ventilation for symptom control and compassionate weaning are also included. CONCLUSION: The timely integration of palliative care into intensive care medicine aims to improve quality of life and symptom control and also takes into acccount the often urgently needed support for patients' highly stressed relatives.

[Recommendations for Education in Sonography in Prehospital Emergency Medicine (pPOCUS): Consensus paper of DGINA, DGAI, BAND, BV-ÄLRD, DGU, DIVI and DGIIN]. / Empfehlungen zur Sonografieausbildung in der prähospitalen Notfallmedizin (pPOCUS): Konsensuspapier von DGINA, DGAI, BAND, BV-ÄLRD, DGU, DIVI und DGIIN.

Point-of-care sonography is a precondition in acute and emergency medicine for the diagnosis and initiation of therapy for critically ill and injured patients. While emergency sonography is a mandatory part of the training for clinical acute and emergency medicine, it is not everywhere required for prehospital emergency medicine. Although some medical societies in Germany have already established their own learning concepts for emergency ultrasound, a uniform national training concept for the use of emergency sonography in the out-of-hospital setting is still lacking. Experts of several professional medical societies have therefore joined forces and developed a structured training concept for emergency sonography in the prehospital setting. The consensus paper serves as quality assurance in prehospital emergency sonography.

Machine learning-based prediction of in-hospital death for patients with takotsubo syndrome: The InterTAK-ML model.

AIMS: Takotsubo syndrome (TTS) is associated with a substantial rate of adverse events. We sought to design a machine learning (ML)-based model to predict the risk of in-hospital death and to perform a clustering of TTS patients to identify different risk profiles. METHODS AND RESULTS: A ridge logistic regression-based ML model for predicting in-hospital death was developed on 3482 TTS patients from the International Takotsubo (InterTAK) Registry, randomly split in a train and an internal validation cohort (75% and 25% of the sample size, respectively) and evaluated in an external validation cohort (1037 patients). Thirty-one clinically relevant variables were included in the prediction model. Model performance represented the primary endpoint and was assessed according to area under the curve (AUC), sensitivity and specificity. As secondary endpoint, a K-medoids clustering algorithm was designed to stratify patients into phenotypic groups based on the 10 most relevant features emerging from the main model. The overall incidence of in-hospital death was 5.2%. The InterTAK-ML model showed an AUC of 0.89 (0.85-0.92), a sensitivity of 0.85 (0.78-0.95) and a specificity of 0.76 (0.74-0.79) in the internal validation cohort and an AUC of 0.82 (0.73-0.91), a sensitivity of 0.74 (0.61-0.87) and a specificity of 0.79 (0.77-0.81) in the external cohort for in-hospital death prediction. By exploiting the 10 variables showing the highest feature importance, TTS patients were clustered into six groups associated with different risks of in-hospital death (28.8% vs. 15.5% vs. 5.4% vs. 1.0.8% vs. 0.5%) which were consistent also in the external cohort. CONCLUSION: A ML-based approach for the identification of TTS patients at risk of adverse short-term prognosis is feasible and effective. The InterTAK-ML model showed unprecedented discriminative capability for the prediction of in-hospital death.

[Gastrointestinal and hepatic emergencies in acute and emergency care]. / Gastrointestinale und hepatologische Notfälle in der klinischen Akut- und Notfallmedizin.

Acute gastrointestinal emergencies are one of the most common presentations to the emergency department. If the main symptom is acute abdominal pain, this is referred to as "acute abdomen". An acute abdomen demands urgent attention and treatment and can be caused by different pathologies (e.g., peptic ulcer disease, acute pancreatitis, diverticulitis). Hepatic emergencies include acute liver failure and acute-on-chronic liver failure. Due to the large number of possible differential diagnoses with variable clinical symptoms, rapid diagnosis of the underlying etiology of gastrointestinal and liver emergencies is a major challenge in daily clinical practice. A structured approach and prompt initiation of adequate diagnostic and treatment measures are essential in order to reduce mortality.

[Children visiting intensive care units and emergency departments : Kids are welcome!] / Besuche von minderjährigen Angehörigen in der Intensiv- und Notfallmedizin : Kinder als Besucher willkommen!

In this white paper, key recommendations for visitation by children in intensive care units (ICU; both pediatric and adult), intermediate care units and emergency departments (ED) are presented. In ICUs and EDs in German-speaking countries, the visiting policies for children and adolescents are regulated very heterogeneously: sometimes they are allowed to visit patients without restrictions in age and time duration, sometimes this is only possible from the age of teenager on, and only for a short duration. A request from children to visit often triggers different, sometimes restrictive reactions among the staff. Management is encouraged to reflect on this attitude together with their employees and to develop a culture of family-centered care. Despite limited evidence, there are more advantages for than against a visit, also in hygienic, psychosocial, ethical, religious, and cultural aspects. No general recommendation can be made for or against visits. The decisions for a visit are complex and require careful consideration.
