RESUMO
Anaemia is a risk factor for several adverse postoperative outcomes. Detailed data about the prevalence of anaemia are not available over a long time-period in Germany. In this retrospective, observational, multicentre study, patients undergoing surgery in March in 2007, 2012, 2015, 2017 and 2019 were studied. The primary objective was the prevalence of anaemia at hospital admission. The secondary objectives were the association between anaemia and the number of units of red blood cells transfused, length of hospital stay and in-hospital mortality. A total of 23,836 patients were included from eight centres. The prevalence of pre-operative anaemia in patients aged ≥ 18 years decreased slightly from 37% in 2007 to 32.5% in 2019 (p = 0.01) and increased in patients aged ≤ 18 years from 18.8% in 2007 to 26.4% in 2019 (p > 0.001). The total amount of blood administered per 1000 patients decreased from 671.2 units in 2007 to 289.0 units in 2019. Transfusion rates in anaemic patients declined from 33.8% in 2007 to 19.1% in 2019 (p < 0.001) and in non-anaemic patients from 8.4% in 2007 to 3.4% in 2019 (p < 0.001). Overall, the mortality rate remained constant over the years: 2.9% in 2007, 2.1% in 2012, 2.5% in 2015, 1.9% in 2017 and 2.5% in 2019. In the presence of anaemia, mortality was significantly increased compared with patients without anaemia (OR 5.27 (95%CI 4.13-6.77); p < 0.001). Red blood cell transfusion was associated with an increased risk of mortality (OR 14.98 (95%CI 11.83-19.03); p < 0.001). Using multivariable linear regression analysis with fixed effects, we found that pre-operative anaemia (OR 2.08 (95%CI 1.42-3.05); p < 0.001) and red blood cell transfusion (OR 4.29 (95%CI 3.09-5.94); p < 0.001) were predictors of mortality but not length of stay (0.99 (95%CI 0.98-1.00) days; p = 0.12) and analysed years (2007 vs. 2019: OR 1.49 (95%CI 0.86-2.69); p = 0.07). Pre-operative anaemia affects more than 30% of surgical patients in Germany and multidisciplinary action is urgently required to reduce adverse outcomes.

BACKGROUND: SARS-CoV-2 has massively changed the care situation in hospitals worldwide. Although tumour care should not be affected, initial reports from European countries were suggestive for a decrease in skin cancer during the first pandemic wave and only limited data are available thereafter. OBJECTIVES: The aim of this study was to investigate skin cancer cases and surgeries in a nationwide inpatient dataset in Germany. METHODS: Comparative analyses were performed in a prepandemic (18 March 2019 until 17 March 2020) and a pandemic cohort (18 March 2020 until 17 March 2021). Cases were identified and analysed using the WHO international classification of diseases codes (ICDs) and process key codes (OPSs). RESULTS: Comparing the first year of the pandemic with the same period 1 year before, a persistent decrease of 14% in skin cancer cases (n = 19 063) was observed. The largest decrease of 24% was seen in non-invasive in situ tumours (n = 1665), followed by non-melanoma skin cancer (NMSC) with a decrease of 16% (n = 15 310) and malignant melanoma (MM) with a reduction of 7% (n = 2088). Subgroup analysis showed significant differences in the distribution of sex, age, hospital carrier type and hospital volume. There was a decrease of 17% in surgical procedures (n = 22 548), which was more pronounced in minor surgical procedures with a decrease of 24.6% compared to extended skin surgery including micrographic surgery with a decrease of 15.9%. CONCLUSIONS: Hospital admissions and surgical procedures decreased persistently since the beginning of the pandemic in Germany for skin cancer patients. The higher decrease in NMSC cases compared to MM might reflect a prioritization effect. Further evidence from tumour registries is needed to investigate the consequences of the therapy delay and identify the upcoming challenges in skin cancer care.

Point-of-care viscoelastic coagulation tests are used increasingly and enable physicians to run precise whole blood coagulation diagnostics. However, the somewhat complicated and abstract presentation of results may hinder these advantages. For this reason, we developed the Visual Clot as an alternative mode of presentation for thrombelastometric data. An algorithm takes existing parameters from rotational thromboelastometry and creates a visual representation in the form of an animated blood clot named 'Visual Clot'. In a prospective international dual-centre study, 60 physicians were presented with rotational thromboelastometry results in the standard way or as a Visual Clot. They were then asked to make therapeutic decisions based on pathological findings. Overall proportion of correct therapeutic decisions was median (IQR [range] 100 (83-100 [39-100]) % for Visual Clot vs. 44 (25-50 [0-83]) % for standard rotational thromboelastometry presentation of results, p < 0.001. Mixed regression models yielded a mean OR (95%CI) 22.1 (13.4-36.5), p < 0.001 for correct decisions with the Visual Clot compared with standard rotational thromboelastometry, with an 18.7 (16.4-21.1), p < 0.001 second decrease in decision time. Perceived cognitive work-load was lower, and participants rated their diagnostic confidence to be higher with the Visual Clot, both p < 0.001. Although correct interpretation of standard rotational thromboelastometry results depended on previous rotational thromboelastometry knowledge and experience, Visual Clot interpretation did not. The Visual Clot improved rotational thromboelastometry-based therapeutic decisions, as pathologies can be recognised more rapidly and accurately. These findings underline the significance of an alternative additional visualisation technique that simplifies the interpretation of abstract standard data.

As COVID-19 disease escalates globally, optimising patient outcome during this catastrophic healthcare crisis is the number one priority. The principles of patient blood management are fundamental strategies to improve patient outcomes and should be given high priority in this crisis situation. The aim of this expert review is to provide clinicians and healthcare authorities with information regarding how to apply established principles of patient blood management during the COVID-19 pandemic. In particular, this review considers the impact of the COVID-19 pandemic on blood supply and specifies important aspects of donor management. We discuss how preventative and control measures implemented during the COVID-19 crisis could affect the prevalence of anaemia, and highlight issues regarding the diagnosis and treatment of anaemia in patients requiring elective or emergency surgery. In addition, we review aspects related to patient blood management of critically ill patients with known or suspected COVID-19, and discuss important alterations of the coagulation system in patients hospitalised due to COVID-19. Finally, we address special considerations pertaining to supply-demand and cost-benefit issues of patient blood management during the COVID-19 pandemic.

More than 30% of all patients undergoing surgery suffer from preoperative anemia. Iron deficiency anemia is the most common type of anemia. The diagnostics and treatment of iron deficiency anemia can be carried out before patients undergo surgery as an alternative to blood transfusion and is an interdisciplinary task. This article gives an overview of various billing modalities and payment arrangements for management of preoperative anemia in the German healthcare system.

Catecholamine crises associated with pheochromocytoma may cause life-threatening cardiovascular conditions. We report the case of a 75-year-old male who developed a hypertensive crisis during induction of general anesthesia for elective resection of a cervical neuroma due to an undiagnosed pheochromocytoma. Hemodynamic instability occurred immediately after the injection of fentanyl, propofol and rocuronium, prior to laryngoscopy and in the absence of any manipulation of the abdomen. In this case report, we present the management of this incident and discuss the underlying pathophysiology triggering a catecholamine crisis.

In 1985 Mallampati et al. published a non-invasive score for the evaluation of airways (Mallampati grading scale, MGS), which originally consisted of only three different classes and has been modified several times. At present it is mostly used in the version of Samsoon and Young consisting of four different classes. Class I: soft palate, fauces, uvula, palatopharyngeal arch visible, class II: soft palate, fauces, uvula visible, class III: soft palate, base of the uvula visible and class IV: soft palate not visible. Nevertheless, other versions of MGS still exist, each having different values for sensitivity and specification. The current opinion is therefore that MGS is no longer useful as a stand-alone predictor but in combination with others it is still part of today's most relevant guidelines, such as those of the American Society of Anesthesiologists (ASA), the UK's Difficult Airway Society (DAS), the European Society of Anaesthesiology (ESA) and the German Society for Anesthesiology and Intensive Care Medicine (DGAI) and must therefore be known by anesthetists. Even in times of sophisticated tools for airway management, the procedure remains a high risk, so every anesthetist has to be prepared for and well trained in management of known and unexpected difficult airways. Evaluation of the patient's airway is a part of modern airway management to prevent problems and reduce risk of hypoxia during the procedure. The theoretical knowledge and practical skills of European anesthetists were evaluated at two international congresses, the German Anesthesia Congress (DAC) and Euroanaesthesia 2014. The DAC is an annual meeting of German speaking anesthetists, hosted by the DGAI. The Euroanaesthesia is the annual European pendant hosted by the ESA. Participation was voluntary and only physicians were allowed to take part. Theory was evaluated by a questionnaire containing open and closed questions for MGS that had to be answered by every participant alone. Apart from theory, a practical evaluation was performed. Every participant had to classify the MGS of a human airway model. The model was identical on both congresses. According to the original publication a checklist containing the factors essential for the correct performance was filled out by a supervising experienced anesthetist. During DAC 2014 nâ¯= 267 physicians participated in the study, 22 participants were excluded due to inconsistent answers, incomplete questionnaires or missing practical part. A total of 245 data sets were evaluated. During Euroanaesthesia 2014 nâ¯= 298 physicians participated in the study, 68 participants were excluded due to inconsistent answers, incomplete questionnaires or missing practical part and 230 data sets were evaluated. At the DAC the mean age (± SD) was 44.5⯱ 9.5 years, 157 (64.1%) were male and 88 (35.9%) were female. Working experience was trainee anesthetist in 16.7% and other participants were experienced anesthetists. At the ESA the mean age (± SD) was 42.4⯱ 9.5 years, 133 (57.8%) were male and 97 (42.2%) female. Trainee anesthetists were 15.2%, the rest were experienced anesthetists. The DAC participants knew Mallampati classes 1 (65%) and 4 (45%) better than 2 and 3 and there was no relevant differences to the ESA (close to 30% knew the classes 1-4 here). Classification of the airway model was correct in 62% and 67% at DAC and ESA, respectively. Most participants performed the practical evaluation correctly except the sitting position of the model. In agreement with earlier studies, these results show the lack of knowledge in evaluation of airways according to current guidelines of all relevant societies. This is likely to increase preventable risks for patients as unexpected difficult airway management increases the risk for hypoxia and intubation damage.

Predicting and managing the difficult airway is a lifesaving and vital basic task for the anesthetist. Current guidelines of all important societies include thyromental distance (TMD, "Patil") as a possible predictor for a difficult airway and includes two important aspects for airway management: the mandibular space and the flexibility of the cervical spine. We evaluated knowledge and execution regarding TMD for predicting a difficult airway on participants at the Euroanaesthesia (ESA) congress and German Anaesthesia Congress (DAC) in 2014. Our evaluation consisted of a theoretical part with questions regarding general knowledge and a practical evaluation with anesthetists performing on a human airway model. Practical evaluations were performed separately from other participants. During the DAC 245 (ESA 230) physicians participated, of which 64% were male (ESA 58%). At the DAC 182 (74.3%) and ESA 82 (35.6%) participants knew about Patil/TMD. Its use as a predictive score for a difficult airway was known by 122 (49.8%; DAC) and 79 (34.4%; ESA) participants. The correct definition for intubation was given by 45 (25.7%) at the DAC and 56 (24.3%) at ESA. Only 40-41% of the participants measured the correct distance for TMD. Only 6.1-6.5% completed both the theoretical and practical parts correctly. As non-invasive TMD includes two different aspects of patient airways and is part of current guidelines, education and training must be extended to assure adequate evaluation in the future.

BACKGROUND AND OBJECTIVES: Platelet transfusions are widely administered to restore perioperative haemostasis in haemorrhagic patients; however, the role of platelet transfusion is not well understood and administration is often based on empiric data. This review aims to explore consensus regarding platelet transfusion trigger, dose and how the haemostatic efficacy of platelet transfusion was assessed for the treatment of perioperative bleeding. MATERIALS AND METHODS: A literature search was carried out using MEDLINE (PubMed) on 28 February 2017, to identify publications reporting the effect of platelet transfusion in relation to triggers, dose and assessment of haemostatic efficacy in bleeding patients in a perioperative setting. RESULTS: Eight publications were identified across a variety of settings, covering both prophylactic and therapeutic platelet transfusion in adult patients; the majority of the reports were in cardiac surgery. A high degree of variability was observed in the published studies, with only 50% of articles specifying a trigger for platelet transfusion. The most commonly used trigger was platelet count (25% of publications), with no consensus identified regarding the platelet count values used as triggers. Doses reported per transfusion varied from 1 to 12 units, and outcome measures were mixed, although the majority of publications (63%) assessed the requirement for transfusion with other blood products. CONCLUSION: The lack of consensus in published studies hinders our ability to draw conclusions regarding platelet transfusion and highlights the need for further studies to assess the appropriate dose and triggers for use in perioperative patients.

Modern trauma room management requires interdisciplinary teamwork and synchronous communication between a team of anaesthesists, surgeons and radiologists. As the length of stay in the trauma room influences morbidity and mortality of a severely injured person, optimizing time is one of the main targets. With the direct involvement of modern imaging techniques the injuries caused by trauma should be detected within a very short period of time in order to enable a priority-orientated treatment. Radiology influences structure and process quality, management and development of trauma room algorithms regarding the use of imaging techniques. For the individual case interventional therapy methods can be added. Based on current data and on the Frankfurt experience the current diagnostic concepts of trauma diagnostics are presented.

Factor XIII (FXIII) plays an important role in the field of blood coagulation. In the last decade, both congenital and acquired deficiencies have been investigated in clinical studies. FXIII is a versatile enzyme that leads to a covalent cross-linking of fibrin fibrils at the end of the clotting cascade and supports platelet adhesion to the damaged sub-endothelium with the result of a mechanically stable clot.Symptoms of FXIII deficiencies vary within a broad spectrum from superficial skin bleeding episodes to severe, sometimes life threatening hemorrhage, requiring prophylactic or therapeutic replacement therapy.Since 1993 purified plasma-derived FXIII concentrate has been available in Germany, large parts of Europe and in the USA and Canada. The administration is conducted intravenously, and FXIII is immediately available in the plasma. The dosage should be determined by measuring actual plasma FXIII-activity. Repetitive application is possible, especially with regard to the mean half-time of 7.9 days.Administration is considered to be safe and effective, but there are some case reports, as with other coagulation factors, describing the appearance of inhibitory antibodies.This summary seeks to provide an insight into the principle pharmacokinetic and pharmacodynamic characteristics of plasma-derived FXIII concentrate, reviewing the current literature. For detailed use in clinical settings, the application of FXIII concentrate or substitution therapy with fresh frozen plasma, we therefore refer to current guidelines and significant studies that have been recently published.

BACKGROUND: Trauma-induced coagulopathy, one of the leading causes of trauma-related death, is detected in about one of four trauma patients upon hospital admission. The current European Management of Major Bleeding and Coagulopathy Following Trauma guidelines, published in 2013, recommend that tranexamic acid (TXA) be administered as early as possible to inhibit hyperfibrinolysis (grade of recommendation (GoR 1A)). Furthermore, it is suggested that protocols for the management of patients with bleeding or showing signs of bleeding include the administration of the first dose of TXA at the site of injury or during transportation to hospital (GoR 2C). There is no current data showing to what extent TXA is used in the pre-hospital settings in Germany. OBJECTIVES: This study aimed to collect data about the availability of TXA in the German emergency medical service (EMS). We tried to determine how many EMS stored and used TXA, under which circumstances the substance was used and whether any standard operating procedures (SOPs) were in use. The study also tried to determine what dosage recommendations exist. MATERIALS AND METHODS: Between 1 July and 31 August 2015, a total of 326 German emergency medical directors (EMDs) were asked to take part in a survey, which involved answering an online questionnaire. RESULTS: Altogether 163 EMD answered the questionnaire (response rate 50%). The results showed that 52.8% of EMDs stored TXA in their vehicles and 26% planned to do so in the future. The availability of TXA in the EMS has increased since 2010. Most EMDs stated that guidelines were the reason for this. SOPs existed in 17.4%. Dosage recommendations were defined by the EMDs in 76.7%. More than 80% of dosage recommendations followed the European guideline. CONCLUSION: The survey shows a widespread distribution of TXA in the German EMS, which has significantly increased between 2010 and 2015. However, nationwide distribution has not yet been established. This rise in distribution is interpreted as a reaction to national and European guidelines for the management of severe bleeding and trauma care. A remaining question is to determine which patients should be treated with TXA, as hyperfibrinolysis is not detectable at the site of injury.

BACKGROUND AND OBJECTIVES: Patient Blood Management (PBM) in Europe is a working group of the European Blood Alliance with the initial objective to identify the starting position of the participating hospitals regarding PBM for benchmarking purposes, and to derive good practices in PBM from the experience and expertise in the participating teams with the further aim of implementing and strengthening these practices in the participating hospitals. METHODS: We conducted two surveys in seven university hospitals in Europe: Survey on top indications for red blood cell use regarding usage of red blood cells during 1 week and Survey on PBM organization and activities. RESULTS: A total of 3320 units of red blood cells were transfused in 1 week at the seven hospitals. Overall, 61% of red cell units were transfused to medical patients and 36% to surgical patients, although there was much variation between hospitals. The organization and activities of PBM in the seven hospitals were variable, but there was a common focus on optimizing the treatment of bleeding patients, monitoring the use of blood components and treatment of preoperative anaemia. CONCLUSION: Although the seven hospitals provide a similar range of clinical services, there was variation in transfusion rates between them. Further, there was variable implementation of PBM activities and monitoring of transfusion practice. These findings provide a baseline to develop joint action plans to further implement and strengthen PBM across a number of hospitals in Europe.

BACKGROUND: Healthcare personnel may be faced with different degrees of violence and aggression, particularly concerning preclinical care. However, systematic data with respect to the frequency and type of violence in emergency medicine in Germany has not been researched. METHODS AND OBJECTIVES: At an anesthesiology congress, an anonymous survey was distributed about the different kinds and extent of violent acts that the participants had experienced during their work in emergency medicine. Moreover, the participants' subjective feelings toward professional and personal safety when handling emergency cases were explored. RESULTS: Every fourth participant in the survey (25.2 %) had experienced occupational physical violence within the last 12 months. Verbal harassment or insults within the last twelve months were reported by 58.2 % of the participants. While 80 % of the participants feel "entirely" or "mostly" safe with regard to the professional aspect of their occupation, personal safety was considered "entirely" in only 9.3 % and "mostly" in 46.4 % of the cases. Nearly every third participant (31.8 %) feels only "partially" safe and every eighth participant feels "rather not" or "not at all" safe during emergency medicine missions. Men appreciate their expertise as well as their personal safety more so than women (p < 0.001). CONCLUSION: Aggression and violence towards healthcare personnel in emergency medicine occur on a regular basis in the German healthcare system. Little research has been conducted in this area, so the issue has not yet been perceived as a relevant problem. Appropriate training for healthcare personnel in emergency medicine should be targeted at developing the skills needed when encountered with aggression and occupational violence.

BACKGROUND: Patient blood management (PBM) is a multidisciplinary approach focusing on the diagnosis and treatment of preoperative anaemia, the minimisation of blood loss, and the optimisation of the patient-specific anaemia reserve to improve clinical outcomes. Economic aspects of PBM have not yet been sufficiently analysed. OBJECTIVES: The aim of this study is to analyse the costs associated with the clinical principles of PBM and the project costs associated with the implementation of a PBM program from an institutional perspective. MATERIALS AND METHODS: Patient-related costs of materials and services were analysed at the University Hospital Frankfurt for 2013. Personnel costs of all major processes were quantified based on the time required to perform each step. Furthermore, general project costs of the implementation phase were determined. RESULTS: Direct costs of transfusing a single unit of red blood cells can be calculated to a minimum of 147.43. PBM-associated costs varied depending on individual patient requirements. The following costs per patient were calculated: diagnosis of preoperative anaemia 48.69-123.88; treatment of preoperative anaemia (including iron-deficiency anaemia and megaloblastic anaemia) 12.61-127.99; minimising perioperative blood loss (including point-of-care diagnostics, coagulation management and cell salvage) 3.39-1,901.81; and costs associated with the optimisation of the tolerance to anaemia (including patient monitoring and volume therapy) 28.62. General project costs associated with the implementation of PBM were 24,998.24. CONCLUSIONS: PBM combines various alternatives to the transfusion of red blood cells and improves clinical outcome. Costs of PBM vary from institution to institution and depend on the extent to which different aspects of PBM have been implemented. The quantification of costs associated with PBM is essential in order to assess the economic impact of PBM, and thereby, to efficiently re-allocate health care resources. Costs were determined at a single university hospital. Thus, further analyses of both the costs of transfusion and the costs of PBM-principles will be necessary to evaluate the cost-effectiveness of PBM.

OBJECTIVE: Risk factors for adverse outcome after extracorporeal life support (ECLS) are yet to be defined. For this purpose, we reviewed our institutional data from more than a decade, focusing on patients with ECLS. METHODS: Between December 2001 and June 2013, 360 consecutive cardiac surgical patients received ECLS for post-cardiotomy cardiogenic shock, with high mortality risk despite optimal conventional therapy. Patient demographics, clinical characteristics, ECLS-related morbidity, as well as in-hospital and long-term mortality were analysed. Multivariate logistic regression analysis was performed to identify independent predictors of adverse outcome (failed ECLS weaning, in-hospital mortality). RESULTS: The mean age was 62±17 years, 76% were male and the mean preoperative ejection fraction was 35±16%. ECLS was established through peripheral (90%) or central thoracic cannulation. The mean duration of ECLS was 7±1 days. Intra-aortic balloon pumps were implanted in 22% of the patients. ECLS weaning was successful in 58% and 30% could be discharged from hospital. The main cause of death was sepsis (69%). Overall, major cerebrovascular events occurred in 12% (bleeding 3%, embolic 9%), limb ischaemia in 13%, gastrointestinal complications in 16% and renal replacement therapy in 61%. Independent risk factors for adverse outcome were prior cardiorespiratory resuscitation (OR: 4.1, 95%CI: 0.34-4.21, p=0.04), pH <7.1 (OR: 2.8, 95%CI: 0.45-3.28, p=0.01), serum lactate >120 mg/dL (OR: 2.6, 95%CI: 0.75-2.96, p< 0.01), norepinephrine dosage >0.5 µg/kg/min (OR: 2.4, 95%CI: 0.35-2.92, p=0.02) and age >75 years (OR: 2.0, 95%CI: 0.41-2.88, p=0.02). Kaplan Meier estimates for long-term survival were 26±3% at one year and 22±2% at five years. CONCLUSION: ECLS therapy offers one-year survival to one quarter of patients with an otherwise fatal prognosis. Procedural mortality is low and morbidity at the implantation site typically moderate. Thus, prolonged metabolic deterioration in combination with high-dose vasopressor support prior to ECLS therapy should be avoided, particularly in younger patients.

BACKGROUND: Trauma care personnel are at risk of occupational exposure to blood-borne pathogens. Little is known regarding compliance with standard precautions or occupational exposure to blood and body fluids among multiple trauma care personnel in Germany. AIM: Compliance rates of multiple trauma care personnel in applying standard precautions, knowledge about transmission risks of blood-borne pathogens, perceived risks of acquiring hepatitis B, hepatitis C and human immunodeficiency virus (HIV) and the personal attitude towards testing of the index patient for blood-borne pathogens after a needlestick injury were evaluated. MATERIAL AND METHODS: In the context of an advanced multiple trauma training an anonymous questionnaire was administered to the participants. RESULTS: Almost half of the interviewees had sustained a needlestick injury within the last 12 months. Approximately three quarters of the participants were concerned about the risk of HIV and hepatitis. Trauma care personnel had insufficient knowledge of the risk of blood-borne pathogens, overestimated the risk of hepatitis C infection and underused standard precautionary measures. Although there was excellent compliance for using gloves, there was poor compliance in using double gloves (26.4 %), eye protectors (19.7 %) and face masks (15.8 %). The overwhelming majority of multiple trauma care personnel believed it is appropriate to test an index patient for blood-borne pathogens following a needlestick injury. CONCLUSION: The process of treatment in prehospital settings is less predictable than in other settings in which invasive procedures are performed. Periodic training and awareness programs for trauma care personnel are required to increase the knowledge of occupational infections and the compliance with standard precautions. The legal and ethical aspects of testing an index patient for blood-borne pathogens after a needlestick injury of a healthcare worker have to be clarified in Germany.
