- [Publication performances of university clinics for anesthesiology : Germany, Austria and Switzerland from 2001 to 2010]. [English Abstract, Journal Article]
- Anaesthesist 2014 Apr; 63(4):287-93.
This study assessed the publication performance of university departments of anesthesiology in Austria, Germany and Switzerland. The number of publications, original articles, impact factors and citations were evaluated.A search was performed in PubMed to identify publications related to anesthesiology from 2001 to 2010. All articles from anesthesiology journals listed in the fields of anesthesia/pain therapy, critical care and emergency medicine by the "journal citation report 2013" in Thomson Reuters ISI web of knowledge were included. Articles from non-anaesthesiology journals, where the stem of the word anesthesia (anes*, anaes*, anäst*, anast*) appears in the affiliation field of PubMed, were included as well. The time periods 2001-2005 and 2006-2010 were compared. Articles were allocated to university departments in Austria, Germany and Switzerland via the affiliation field.A total of 45 university departments in Austria, Germany and Switzerland and 125,979 publications from 2,863 journals (65 anesthesiology journals, 2,798 non-anesthesiology journals) were analyzed. Of the publications 23 % could not be allocated to a given university department of anesthesiology. In the observation period the university department of anesthesiology in Berlin achieved most publications (n = 479) and impact points (1,384), whereas Vienna accumulated most original articles (n = 156). Austria had the most publications per million inhabitants in 2006-2010 (n=50) followed by Switzerland (n=49) and Germany (n=35). The number of publications during the observation period decreased in Germany (0.5 %), Austria (7 %) and Switzerland (8 %). Tables 2 and 4-8 of this article are available at Springer Link under Supplemental.The research performance varied among the university departments of anesthesiology in Germany, Austria and Switzerland whereby larger university departments, such as Berlin or Vienna published most. Publication output in Germany, Austria and Switzerland has decreased. Data processing in PubMed should be improved.
- [Modified McPeek score in multiple trauma patients : Prospective evaluation of a points system for recording follow-up factors.] [JOURNAL ARTICLE]
- Anaesthesist 2014 Apr 10.
Many commonly available trauma scores predict mortality, but to evaluate the success of a certain therapy or for difficult scientific and epidemiological purposes this may be insufficient in the face of improved survival rates. For outcome analysis of multiple trauma patients, the extent of medical resources needed could be an additional outcome measurement. McPeek et al. developed a potential scoring system for elective surgery patients, which was recently modified for multiple trauma patients.The current study investigated if the McPeek score could be prospectively used in multiple trauma patients and whether it could become an additional helpful tool in outcome assessment. Applicability was assessed by practical examples.In this prospective single-centre study at the University Hospital of Innsbruck, Austria, between December 2008 and November 2010 multiple trauma patients (≥ 18 years) with an injury severity score (ISS) ≥ 17 were enrolled. Besides demographic data, prehospital vital parameters and diagnoses, all diagnoses from the trauma, mortality, length of stay in the intensive care unit and the hospital were recorded. The commonly used trauma scores ISS, revised trauma score (RTS), a severity characterization of trauma (ASCOT) and trauma and injury severity score (TRISS) were applied and an observed McPeek score was allocated following end of hospitalization. The McPeek scoring system was used according to the latest modifications. A correlation between trauma scores and the McPeek score was performed. The McPeek score was then predicted by a common trauma score using ordinal regression with the polytomous universal model (PLUM method). By subtracting the predicted from the observed McPeek scores the residual McPeek value was calculated and used for practical examples of outcome analysis with the McPeek scoring system.Out of 406 identified multiple trauma patients during the study phase, 183 had to be excluded due to missing data (mainly prehospital or following transfer). A total of 223 patients (mean ISS 31.2, mean age 47.2 years) were enrolled and assigned to the population-based observed McPeek score (median 4.0). Correlation coefficients were Glasgow coma scale (GCS) 0.59, ISS 0.62, RTS 0.65, TRISS 0.74 and ASCOT 0.77 (p < 0.0001). The TRISS predicted the McPeek score best in ordinal regression (pseudo-R(2) = 0.944, p < 0.0001). The residual McPeek score (observed minus predicted) was used to illustrate the influence of the blood glucose level on admission and the influence of head injury on outcome of multiple injury patients in detail.The modified McPeek score is applicable to multiple trauma patients to assess outcome for scientific or epidemiological purposes. Its main advantage is that it quantifies outcome independently of regional or national circumstances.
- [Localization of peripheral nerves : Success and safety with electrical nerve stimulation.] [JOURNAL ARTICLE]
- Anaesthesist 2014 Apr 10.
Peripheral electrical nerve stimulation is one of the standard applications in peripheral regional anesthesia in addition to the ultrasound technique. Among other findings, the visualization of needle and nerve during ultrasound-guided blockade caused a change in clinical practice of peripheral nerve stimulation in the last decade. In the present article old and new aspects of principles and clinical practice of the nerve stimulation technique are presented and summarized in a total clinical concept in order to achieve safe and successful peripheral regional anesthesia using electrical peripheral nerve stimulation.
- [New oral anticoagulants in perioperative medicine]. [English Abstract, Journal Article]
- Anaesthesist 2014 Apr; 63(4):347-64.
New oral anticoagulants (NOAC) inhibit factor Xa (Stuart-Prower factor) or factor IIa (thrombin) and are alternatives to vitamin K antagonists. Perioperative indications are deep vein thrombosis prophylaxis for prosthetic hip and knee replacement, therapeutic anticoagulation for deep vein thrombosis as well as the prophylaxis of stroke for patients with atrial fibrillation. Patients on NOACs pose multiple perioperative challenges for all medical disciplines involved. For non-emergency surgery, patients should be evaluated by an anesthesiolgist as early as possible to assess an optimal appointment for surgery and bridging strategy. Management of emergency procedures for patients on NOACs requires an interdisciplinary approach. The individual risk for uncontrolled bleeding versus the urgency for surgery needs to be evaluated on an individual basis. The determination of drug serum levels enables a rough estimation of anticoagulant activity. Emergency procedures in coagulopathy due to active bleeding are treated with the unspecific administration of blood products and coagulation factor concentrates.
- [Prewarming : Yesterday's luxury, today's minimum requirements.] [JOURNAL ARTICLE]
- Anaesthesist 2014 Apr 3.
Prewarming is a useful and effective measure to reduce perioperative hypothermia. Due to §23(3) of the German Infektionsschutzgesetz (Gesetz zur Verhütung und Bekämpfung von Infektionskrankheiten beim Menschen, Infection Act, act on protection and prevention of infectious diseases in man) and the recommendations of the Hospital Hygiene and Infection Prevention Committee of the Robert Koch Institute, implementation of prewarming is clearly recommended. There are several technically satisfactory and practicable devices available allowing prewarming on the normal hospital ward, in the preoperative holding area or in the induction room of the operating theater (OR) The implementation of prewarming requires additional equipment and training of staff. Using a locally adapted concept for the implementation of prewarming does not lead to inefficiency in the perioperative process. In contrast, the implementation can help to achieve stable arrival times for patients in the OR.
- [Prediction of further hospital treatment for emergency patients by emergency medical service physicians.] [JOURNAL ARTICLE]
- Anaesthesist 2014 Apr 3.
Prehospital assessment of illness and injury severity with the National Advisory Committee for Aeronautics (NACA) score and hospital pre-arrival notification of a patient who is likely to need intensive care unit (ICU) or intermediate care unit (IMC) admission are both common in Germany's physician-staffed emergency medical services (EMS) system.This study aimed at comparing the prehospital evaluation of severity of disease or injuries by EMS physicians and the subsequent clinical treatment in unselected emergency department (ED) patients.This study involved a prospective observational analysis of patients transported to the ED of an academic level I hospital escorted by an EMS physician over a period of 6 months (February-July 2011). The physician's qualification and the patient's NACA score were documented and the EMS physician was asked to predict whether the patient would need hospital admission and, if so, to the general ward, IMC or ICU. After the ED treatment, discharge or admission, outcome and length of hospital and ICU or IMC stay were documented.A total of 378 mostly non-trauma patients (88 %) treated by experienced EMS physicians could be enrolled. The number of patients discharged from the ED decreased, while the number of patients admitted to the ICU increased with higher NACA scores. Prehospital prediction of discharge or admission, IMC or ICU treatment by EMS physicians was accurate in 47 % of the patients. In 40 % of patients a lower level of care was sufficient while 12 % needed treatment on a higher level of care than that predicted by EMS physicians. Of the patients 39 % who were predicted to be discharged after ED treatment, were admitted to hospital and 48 % of patients predicted to be admitted to the IMC were admitted to the general ward. Patients predicted to be admitted to the ICU were admitted to the ICU in 75 %. Higher NACA scores were associated with increased mortality and a longer hospital IMC or ICU length of stay, but significant differences were only found between patients with NACA V versus VI scores or patients predicted to be treated on the IMC versus the ICU.Prehospital NACA scores indicate the need for inpatient treatment, but neither hospital discharge or admission nor need of IMC or ICU admission after initial ED treatment could be sufficiently predicted by EMS physicians. Thus, hospital prenotification in order to predispose IMC or ICU capacities does not seem to be useful in cases where an ED can reassess admitted EMS patients.
- [Update on the pharmacology and effects of local anesthetics.] [JOURNAL ARTICLE]
- Anaesthesist 2014 Apr 3.
Local anesthetics (LA) are broadly used in all disciplines and it could be considered that relatively little is reflected on the mechanisms of action of this old substance group. However, several molecular mechanisms of LAs mediating wanted and unwanted effects remain to be explored. Furthermore, the number of indications for application of LAs seems to be expanding. The local anesthetic effect of LAs is primarily mediated by a potent inhibition of voltage-gated sodium channels. However, this effect is due to much more than the interaction of LAs with one single molecule. Most recent studies indicated that the development of selective local anesthetics might be possible and LAs also interact with several other membrane molecules. Although the relevance of these effects is still unclear, they might play a role in systemic analgesia, tissue protection and anti-inflammatory effects of LA. The therapeutic index of systemically applied LA is very narrow. Systemic application is formally not permitted because the impending systemic toxicity is still a life-threatening complication. Although the cardiac and central nervous toxicity at least partly result from an unselective block of neuronal and cardiac sodium channels, preclinical studies suggest the involvement of several mechanisms. A local LA toxicity is less clinically impressive; however, all LAs induce a significant tissue toxicity for which the underlying mechanisms have been partly identified. This review reports on recent findings on mechanisms and on the clinical relevance of some LA-induced effects which are of relevance for anesthesiological activities.
- [A guide to successful public relations for hospitals and emergency medical services]. [English Abstract, Journal Article]
- Anaesthesist 2014 Apr; 63(4):338-46.
Tragic accidents, e.g. involving celebrity patients or severe incidents in hospital occur suddenly without any advance warning, often produce substantial interest by the media and quickly overburden management personnel involved in both hospitals and emergency medical services. While doctors, hospitals and emergency medical services desire objective media reports, the media promote emotionalized and dramatized reports to ensure maximum attention and circulation. When briefing the media, the scales may quickly tilt from professional, well-deliberated information to unfortunate, often unintended disinformation. Such phenomena may result in continuing exaggerated reports in the tabloid press, which in the presence of aggressive lawyers and a competitive hospital environment can turn into image and legal problems. In this article, several aspects are discussed in order to achieve successful public relations.Interviews should be given only after consultation with the responsible press officer and the director of the respective department or hospital director. Requests for information by the media should always be answered as otherwise one-sided, unintentional publications can result that are extremely difficult to correct later. One should be available to be contacted easily by journalists, regular press conferences should be held and critics should be taken seriously and not be brushed off. Questions by journalists should be answered in a timely manner as journalists are continuously under time pressure and do not understand unnecessary delays. Information for the media should always be provided at the same time, no publication should be given preference and an absolutely current list of E-mail contacts is required. When facing big events a press conference is preferred as many questions can be answered at once. Always be well prepared for an interview or even for just a statement. Each interview should be regarded as an opportunity to put a story forward which you wanted to do for a long time and your message should not contain more than three main points.Each hospital or emergency medical service should have a professional department for public relations, an exact knowledge of the regional and national media and strategies how to handle an incident that is of interest for the media. The media should be provided with information not only when a negative incident has happened but should be provided with regular positive messages as well. An interview must be carefully prepared to achieve a good image.

- [National data set "emergency department": development, structure and approval by the Deutsche Interdisziplinäre Vereinigung für Intensivmedizin und Notfallmedizin]. [English Abstract, Journal Article]
- Anaesthesist 2014 Mar; 63(3):243-52.
The Deutsche Interdisziplinäre Vereinigung für Intensivmedizin und Notfallmedizin (DIVI) is divided into sections one of which is the "Sektion Notaufnahmeprotokoll" (emergency department protocol section) founded in 2007. The main task was to create a national data set for the documentation of patients in emergency departments (ED).In order to create such a data set a careful look was taken at the current state of documentation in many different hospitals throughout Germany. In addition, existing registries and international requirements were also taken into consideration. The content of the dataset "ED documentation" was developed in interdisciplinary and interprofessional expert rounds.The dataset "ED documentation" forms the first basis for documentation in German EDs. The modular data set contains 676 fields and covers all relevant information of the whole clinical process in the ED. Legal issues as well as several aspects for internal and external quality management are also included. For this reason the data of several German quality registries (e.g. TraumaRegister DGU® of the German Society of Trauma Surgery) are part of the data set. Furthermore, the data set forms the basis for several financial and billing aspects. A set of six forms was created in accordance with the developed modular data set. In 2010 the data set was approved by the executive committee of the DIVI. Several German medical associations (e.g. German Association for Emergency Medicine/Deutsche Gesellschaft Interdisziplinäre Notfall- und Akutmedizin, DGINA) recommend its use. Currently 80 hospitals are using the data set.Beside the ability to exchange information the presented data set is the basis for internal and external quality assessment in the ED even if most of the available scoring and benchmarking tools are not validated for the German medical system. Implementing an ED register in Germany which is planned in the future, could close this gap.
