[German S3 Guideline - Oxygen Therapy in the Acute Care of Adult Patients]. / S3-Leitlinie Sauerstoff in der Akuttherapie beim Erwachsenen.

BACKGROUND: Oxygen (O2) is a drug with specific biochemical and physiologic properties, a range of effective doses and may have side effects. In 2015, 14 % of over 55 000 hospital patients in the UK were using oxygen. 42 % of patients received this supplemental oxygen without a valid prescription. Healthcare professionals are frequently uncertain about the relevance of hypoxemia and have low awareness about the risks of hyperoxemia. Numerous randomized controlled trials about targets of oxygen therapy have been published in recent years. A national guideline is urgently needed. METHODS: A S3-guideline was developed and published within the Program for National Disease Management Guidelines (AWMF) with participation of 10 medical associations. Literature search was performed until Feb 1st 2021 to answer 10 key questions. The Oxford Centre for Evidence-Based Medicine (CEBM) System ("The Oxford 2011 Levels of Evidence") was used to classify types of studies in terms of validity. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used and for assessing the quality of evidence and for grading guideline recommendation and a formal consensus-building process was performed. RESULTS: The guideline includes 34 evidence-based recommendations about indications, prescription, monitoring and discontinuation of oxygen therapy in acute care. The main indication for O2 therapy is hypoxemia. In acute care both hypoxemia and hyperoxemia should be avoided. Hyperoxemia also seems to be associated with increased mortality, especially in patients with hypercapnia. The guideline provides recommended target oxygen saturation for acute medicine without differentiating between diagnoses. Target ranges for oxygen saturation are depending on ventilation status risk for hypercapnia. The guideline provides an overview of available oxygen delivery systems and includes recommendations for their selection based on patient safety and comfort. CONCLUSION: This is the first national guideline on the use of oxygen in acute care. It addresses healthcare professionals using oxygen in acute out-of-hospital and in-hospital settings. The guideline will be valid for 3 years until June 30, 2024.

[Quality Assurance in Intensive Care Medicine: Peer Reviews and Quality Indicators]. / Qualitätssicherung in der Intensivmedizin: Peer Reviews und Qualitätsindikatoren.

Goal-oriented quality management in health care is an essential tool to provide good medical practice and treatment. It aims at a patient-centred case management with high transparency of structural and clinical process aspects, as well as patient outcome. An objective and comprehensive description of clinical care includes the use of quality indicators. However, the appliance of those indicators falls short, when the evaluation of quality is not followed by recommendations for improvement.As a highly specified area in health care provided in hospitals, intensive care medicine is characterized by complex interprofessional and multidisciplinary approaches. In addition, critical care units are an expensive resource. In order to provide an economic and yet high quality patient care, treatments should be evidence-based, and cost-drivers must be analysed for their effectiveness on patient-outcome.Various methods of quality assurance allow for a formative evaluation of intensive care units by peer reviews, including the use of quality indicators. This article focuses on peer review systems currently applied in German hospitals, and particularly describes quality indicators that have been established by DIVI (German Interdisciplinary Society of Intensive Care and Emergency Medicine). It also addresses the need for a professional dialogue between equal partners. This has to accompany each peer review that aims at an improvement in quality of critical patient care.

Quality indicators in intensive care medicine for Germany - fourth edition 2022.

The measurement of quality indicators supports quality improvement initiatives. The German Interdisciplinary Society of Intensive Care Medicine (DIVI) has published quality indicators for intensive care medicine for the fourth time now. After a scheduled evaluation after three years, changes in several indicators were made. Other indicators were not changed or only minimally. The focus remained strongly on relevant treatment processes like management of analgesia and sedation, mechanical ventilation and weaning, and infections in the ICU. Another focus was communication inside the ICU. The number of 10 indicators remained the same. The development method was more structured and transparency was increased by adding new features like evidence levels or author contribution and potential conflicts of interest. These quality indicators should be used in the peer review in intensive care, a method endorsed by the DIVI. Other forms of measurement and evaluation are also reasonable, for example in quality management. This fourth edition of the quality indicators will be updated in the future to reflect the recently published recommendations on the structure of intensive care units by the DIVI.

[Oxygen in the acute care of adults : Short version of the German S3 guideline]. / Sauerstoff in der Akuttherapie beim Erwachsenen : Kurzversion der S3-Leitlinie.

BACKGROUND: Oxygen is a drug with specific properties, a defined dose-effect range and side effects. In 2015, in a sample of UK hospital patients, 14% were treated with oxygen, of which only 42% had a prescription. Health care workers are often uncertain about the relevance of hypoxemia, and there is limited awareness of the risks of hyperoxemia. Numerous randomized controlled trials on oxygen therapy have recently been published. METHODS: As part of the guideline program of the Working Group of Scientific Medical Societies e. V. (AWMF), this S3 guideline was developed with the participation of 10 medical societies on the basis of a literature search up to 02/01/2021. The system of the Oxford Centre for Evidence-Based Medicine (CEBM) (The Oxford 2011 Levels of Evidence) was used to evaluate the literature. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE), and a formal consensus process of recommendations was performed. RESULTS: The guideline contains 34 evidence-based recommendations on the indication, prescription, monitoring, and discontinuation of oxygen therapy in acute care. The indication for oxygen is mainly hypoxemia. Hypoxemia and hyperoxemia should be avoided, since both increase mortality. The guideline recommends target ranges of oxygen saturation for acute oxygen therapy without differentiating between different diagnoses. Target areas depend on the risk for hypercapnia and ventilation status. The guideline provides an overview of available oxygen delivery systems and contains recommendations for their selection based on patient safety and comfort. CONCLUSION: This is the first German guideline on the use of oxygen in acute care. It is aimed at medical professionals who use oxygen in and outside hospitals and is valid until June 30th, 2024.

Vascular type Ehlers-Danlos syndrome is associated with platelet dysfunction and low vitamin D serum concentration.

BACKGROUND: The vascular type represents a very rare, yet the clinically most fatal entity of Ehlers-Danlos syndrome (EDS). Patients are often admitted due to arterial bleedings and the friable tissue and the altered coagulation contribute to the challenge in treatment strategies. Until now there is little information about clotting characteristics that might influence hemostasis decisively and eventually worsen emergency situations. RESULTS: 22 vascular type EDS patients were studied for hemoglobin, platelet volume and count, Quick and activated partial thromboplastin time, fibrinogen, factor XIII, von Willebrand disease, vitamin D and platelet aggregation by modern standard laboratory methods. Results show a high prevalence of over 50 % for platelet aggregation disorders in vascular type EDS patients, especially for collagen and epinephrine induced tests, whereas the plasmatic cascade did not show any alterations. Additionally, more than half of the tested subjects showed low vitamin D serum levels, which might additionally affect vascular wall integrity. CONCLUSION: The presented data underline the importance of detailed laboratory screening methods in vascular type EDS patients in order to allow for targeted application of platelet-interacting substances that might be of decisive benefit in the emergency setting.

Is the osmole gap a valuable indicator for the need of hemodialysis in severe ethanol intoxication?

Up-to-date no indicator for hemodialysis in severe ethanol intoxication is available. In these cases, the benefits have to outweigh the risks and costs of hemodialysis. In this case report, a suicidal patient had ingested 250 ml of 95% ethanol and was found in deep coma. In literature, some cases, especially of adolescents, are described with severe ethanol poisoning and blood ethanol levels above 740 mg/dL. Hemodialysis, if initiated, decreased ethanol levels significantly as compared to peritoneal dialysis, charcoal or gastric lavage and reduced also clinical costs. While recommendations exist for starting dialysis in ethylene glycol or methanol intoxications, no algorithm is available to determine the situations when hemodialysis is required in ethanol intoxication. The osmole gap may serve as an indicator to differentiate, which patients need haemodialysis - right now, the decision depends upon the physicians experience or preference.

A civilian perspective on ballistic trauma and gunshot injuries.

BACKGROUND: Gun violence is on the rise in some European countries, however most of the literature on gunshot injuries pertains to military weaponry and is difficult to apply to civilians, due to dissimilarities in wound contamination and wounding potential of firearms and ammunition. Gunshot injuries in civilians have more focal injury patterns and should be considered distinct entities. METHODS: A search of the National Library of Medicine and the National Institutes of Health MEDLINE database was performed using PubMed. RESULTS: Craniocerebral gunshot injuries are often lethal, especially after suicide attempts. The treatment of non space consuming haematomas and the indications for invasive pressure measurement are controversial. Civilian gunshot injuries to the torso mostly intend to kill; however for those patients who do not die at the scene and are hemodynamically stable, insertion of a chest tube is usually the only required procedure for the majority of penetrating chest injuries. In penetrating abdominal injuries there is a trend towards non-operative care, provided that the patient is hemodynamically stable. Spinal gunshots can also often be treated without operation. Gunshot injuries of the extremities are rarely life-threatening but can be associated with severe morbidity.With the exception of craniocerebral, bowel, articular, or severe soft tissue injury, the use of antibiotics is controversial and may depend on the surgeon's preference. CONCLUSION: The treatment strategy for patients with gunshot injuries to the torso mostly depends on the hemodynamic status of the patient. Whereas hemodynamically unstable patients require immediate operative measures like thoracotomy or laparotomy, hemodynamically stable patients might be treated with minor surgical procedures (e.g. chest tube) or even conservatively.
