Implementation and adoption of SOAP-M and SBAR at a German anesthesiology department - a single-center survey study.

BACKGROUND: Checklists are a common tool used in order to mitigate risks caused by human factors and can facilitate the safe induction of anesthesia as well as handovers. SBAR (Situation, Background, Assessment, Recommendation) is a checklist recommended by the WHO and DGAI for handovers, while SOAP-M (Suction, Oxygen, Airway, Pharmaceuticals, Monitoring) is a checklist for the induction of anesthesia. This study investigates the implementation and adoption of these two checklists. METHODS: We conducted a single-center online survey one year after the implementation of SOAP-M and SBAR at a university hospital's anesthesiology department, using scales from three validated questionnaires to assess safety attitudes as well as the behavior of staff and the perceived usefulness of the checklists. RESULTS: Staff with a high score in general attitude towards patient safety, as determined by the safety attitudes questionnaire, considered both checklists useful additions to their work environment. Nurses and physicians (p = 0.102) as well as groups divided according to work experience (p = 0.077) showed no significant differences in using SOAP-M and SBAR. Perceived usefulness was significantly higher (p < 0.001) among users of the checklists, and the same goes for positive reinforcement (p < 0.001), social cues (p = 0.0215) and goal cues (p = 0.0252). CONCLUSION: SOAP-M and SBAR are perceived as useful checklists for patient handovers and anesthesia induction by tertiary referral hospital's employees with high score in general safety attitude and were therefore commonly used one year after their introduction. No significant difference in checklist adoption between occupations as well as groups divided according to work experience could be found. Perceived usefulness is significantly higher among users of the checklist, who feel using the checklists provides more support.

Interleukin-18 and High-Mobility-Group-Protein B1 are Early and Sensitive Indicators for Cell Damage During Normothermic Machine Perfusion after Prolonged Cold Ischemic Storage of Porcine Liver Grafts.

In the era of organ machine perfusion, experimental models to optimize reconditioning of (marginal) liver grafts are needed. Although the relevance of cytokine signatures in liver transplantation has been analyzed previously, the significance of molecular monitoring during normothermic machine perfusion (NMP) remains elusive. Therefore, we developed a porcine model of cold ischemic liver graft injury after prolonged static cold storage (SCS) and subsequent NMP: Livers obtained from ten minipigs underwent NMP for 6 h directly after procurement (control group) or after 20 h of SCS. Grafts after prolonged SCS showed significantly elevated AST, ALT, GLDH and GGT perfusate concentrations, and reduced lactate clearance. Bile analyses revealed reduced bile production, reduced bicarbonate and elevated glucose concentrations after prolonged SCS. Cytokine analyses of graft perfusate simultaneously demonstrated an increase of pro-inflammatory cytokines such as Interleukin-1α, Interleukin-2, and particularly Interleukin-18. The latter was the only significantly elevated cytokine compared to controls, peaking as early as 2 h after reperfusion (11,012 ng/ml vs. 1,493 ng/ml; p = 0.029). Also, concentrations of High-Mobility-Group-Protein B1 were significantly elevated after 2 h of reperfusion (706.00 ng/ml vs. 148.20 ng/ml; p < 0.001) and showed positive correlations with AST (r 2 = 0.846) and GLDH (r 2 = 0.918) levels. Molecular analyses during reconditioning of liver grafts provide insights into the degree of inflammation and cell damage and could thereby facilitate future interventions during NMP reducing acute and chronic graft injury.

Correlation between safety attitudes and early adoption of cognitive aids in the German culture sphere: a multicenter survey study.

BACKGROUND: Cognitive Aids (checklists) are a common tool to improve patient safety. But the factors for their successful implementation and continuous use are not yet fully understood. Recent publications suggest safety culture to play a key role in this context. However, the effects on the outcome of implementation measures remain unclear. Hospitals and clinics that are involved in cognitive aid development and research might have significantly different safety cultures than their counterparts, resulting in skewed assessments of proper implementation. Therefore, the objective of this study was to assess the correlation between cognitive aid implementation and safety attitudes of staff members in early adopting and later adopting clinics. METHODS: An online survey of the Safety Attitudes Questionnaire (SAQ) was carried out in German anaesthesiology departments during the initial implementation of a new checklist for emergencies during anesthesia ("eGENA" app). Subsequently an analysis between subgroups ("eGENA" app usage and occupation), with Kruskal-Wallis- and Mann-Whitney-U-Tests was carried out for the general SAQ, as well as it six subscales. RESULTS: Departments that introduced "eGENA" app (Median 3,74, IQR 0,90) reported a significantly higher median SAQ (U (NeGENA = 6, Nnon eGENA = 14) = 70,0, z = 2,31, p = 0,02, r = 0,516) than their counterparts (Median 2,82, IQR 0,77) with significant differences in the dimensions teamwork climate, work satisfaction, perception of management and working conditions. CONCLUSION: Early adopters of cognitive aids are likely to show a significantly higher perception of safety culture in the SAQ. Consequently, successful implementation steps from these settings might not be sufficient in different clinics. Therefore, further investigation of the effects of safety culture on cognitive aid implementation should be conducted.

Incidence and characteristics of errors detected by a short team briefing in pediatric anesthesia.

BACKGROUND: In our institution, a modified WHO surgical safety checklist was implemented more than ten years ago. In retrospect, we noticed that pediatric anesthesia was underrepresented in our surgical safety checklist modification. Therefore, we added a standardized team briefing (pedSOAP-M) immediately before induction of anesthesia and hypothesized that the use of this checklist was effective to detect relevant errors with potentially harmful consequences. AIMS: The primary aim was to assess the incidence and characteristics of the detected errors, and the secondary aim was to identify factors influencing error detection. METHODS: This prospective observational study was performed between November 2020 and October 2021 in five operation rooms at the Children's Hospital of Hannover Medical School, Germany. The subcategories of the pedSOAP-M checklist were suction, oxygen, airway, pharmaceuticals, and monitoring. Demographic and procedure-related data and the briefing results were documented anonymously and undated, using a standardized case report form. RESULTS: We enrolled 1030 and analyzed 1025 patients (aged 0-18 years). Relevant errors were detected in 111 (10.8%) cases (suction 2.5%, oxygen 3.0%, airway 0.2%, pharmaceuticals 2.4%, monitoring 3.0%). In the pharmaceuticals subcategory, the most common error was entering a wrong patient weight into the perfusor syringe pumps. Experienced anesthetists detected significantly more errors than less experienced ones. CONCLUSION: The briefing tool pedSOAP-M was effective in detecting relevant errors with potentially harmful consequences. The presence of an experienced anesthetist was associated with a higher efficacy of the briefing. Particular attention should be given to entering patient weight into the anesthesia workstation and the perfusor syringe pumps.

Influence of presence in an inter-professional simulation training of the emergency caesarean section: a cross-sectional questionnaire study.

PURPOSE: Emergency training using simulation is a method to increase patient safety in the delivery room. The effect of individual training concepts is critically discussed and requires evaluation. A possible influence factor of success can be the perceived reality of the participants. The objective of this study was to investigate whether the presence in a simulated emergency caesarean section improves subjective effect of the training and evaluation. METHODS: In this observation study, professionals took part in simulated emergency caesarean sections to improve workflow and non-technical skills. Presence was measured by means of a validated questionnaire, effects and evaluation by means of a newly created questionnaire directly after the training. Primary outcome was a correlation between presence and assumed effect of training and evaluation. RESULTS: 106 participants (70% of course participants) answered the questionnaires. Reliability of the presence scale was good (Cronbach's alpha 0.72). The presence correlated significantly with all evaluated items of non-technical skills and evaluation of the course. The factor "mutual support" showed a high effect size (0.639), the overall evaluation of the course (0.395) and the willingness to participate again (0.350) a medium effect. There were no differences between the professional groups. CONCLUSION: The presence correlates with the assumed training objectives and evaluation of the course. If training is not successful, it is one factor that needs to be improved.

Structured evaluation of stress triggers in prehospital emergency medical care : An analysis by questionnaire regarding the professional groups.

BACKGROUND: Emergency medical services work in the environment of high responsibility teams and have to act under unpredictable working conditions. Stress occurs and has potential of negative effects on tasks, teamwork, prioritization processes and cognitive control. Stress is not exclusively dictated by the situation-the individuals rate the situation of having the necessary skills that a particular situation demands. There are different occupational groups in the emergency medical services in Germany. Training, tasks and legal framework of these groups vary. OBJECTIVE: The aim of this study was to identify professional group-specific stressors for emergency medical services. These stress situations can be used to design skills building tools to enable individuals to cope with these stressors. MATERIAL AND METHODS: The participants were invited to the study via posters and social media. An expert group (minimum 6 months of experience) developed a set of items via a two-step online Delphi survey. The experts were recruited from all professional groups represented in the German emergency medical service. We evaluated the resulting parameters for relevance and validity in a larger collective. Lastly, we identified stress factors that could be grouped in relevant scales. In total 1017 participants (paramedics, physicians) took part in the final validation survey. RESULTS: After validation, we identified a catalogue of stressors with 7 scales and 25 items for EMT (Emergency Medical Technician) paramedics (KMO [Kayser-Meyer-Olkin criterion] 0.81), 6 scales and 24 items for advanced paramedics (KMO 0.82) and 6 scales and 24 items for EMS (Emergency Medical Service) physicians (KMO 0.82). For the professional group of EMT basic, the quality parameters did not allow further processing of the items. Professional group-specific scales for EMT paramedics are "professional limitations", "organizational framework", "expectations" and "questions of meaning". For advanced paramedics "appreciation", "exceptional circumstances" and "legal certainty" were identified. The EMT physicians named "handling third parties", "tolerance to ambiguity", "task management" and "pressure to act". A scale that is representative for all professional groups is "teamwork". Organizational circumstances occur in all groups. The item "unnecessary missions" for EMT paramedics and "legal concerns with the application of methods" for advanced paramedics are examples. DISCUSSION: Different stressors are relevant for the individual professional groups in the German emergency medical service. The developed catalogue can be used in the future to evaluate the subjective stress load of emergency service professionals. There are stressors that are inherent in the working environment (e.g. pressure to act) and others that can be improved through training (teamwork). We recommend training of general resistance as well as training of specific items (e.g., technical, nontechnical skills). All professionals mentioned items with respect to organizational factors. The responsible persons can identify potential for improvement based on the legal and organizational items. The EMT basic requires further subdivision according to task areas due to its variable applicability.

[Stocked medications in emergency medical service vehicles staffed by physicians-is prehospital treatment according to current guidelines possible?] / Medikamentöse Ausstattung arztbesetzter Rettungsmittel ­ ist eine präklinische Therapie nach aktuellen Leitlinien möglich?

Background: High quality of care in prehospital emergency medicine is characterized by guideline-based therapy. The basic prerequisite for this therapy is the availability of the required drugs in accordance with the current guideline recommendations. It is currently unclear whether this is guaranteed nationwide. There is no uniform standard regarding which drugs must be stocked in emergency medical services (EMS) vehicles staffed by physicians in Germany. The aim of the present study is to identify important diagnoses and the drugs required for their therapy. In a second step, medical directors throughout Germany were interviewed about current drugs available in their physician-staffed EMS vehicles and these were compared with the previously defined diagnosis-dependent drug lists. Materials and methods: After a structured guideline search, tracer diagnoses were defined and relevant drugs were assigned to them. The levels of evidence and recommendations were also considered. In a second step, this was compared with the current drugs available in physician-staffed EMS vehicles. Results: A total of 156 different medications were identified. The median number of medications stocked was 58; the minimum number of medications stocked was 35 at one site, while multiple sites stocked a maximum of 77 medications . Discussion: The present study investigated stocked medications in physician-staffed EMS vehicles. Overall, compared to a 2011 study, drug availability has improved. Most of the recommended medications are available in physician-staffed vehicles in Germany. The data from this study can be used by EMS throughout Germany to evaluate their preparedness.

Supportive Hepatocyte Transplantation after Partial Hepatectomy Enhances Liver Regeneration in a Preclinical Pig Model.

BACKGROUND: Hepatocyte transplantation (HTx) is regarded as a potential treatment modality for various liver diseases including acute liver failure. We developed a preclinical pig model to evaluate if HTx could safely support recovery from liver function impairment after partial hepatectomy. METHODS: Pigs underwent partial hepatectomy with reduction of the liver volume by 50% to induce a transient but significant impairment of liver function. Thereafter, 2 protocols for HTx were evaluated and compared to a control group receiving liver resection only (group 1, n = 5). Portal pressure-controlled HTx was performed either immediately after surgery (group 2, n = 6) or 3 days postoperatively (group 3, n = 5). In all cases, liver regeneration was monitored by conventional laboratory tests and the novel noninvasive maximum liver function capacity (LiMAx) test with a follow-up of 4 weeks. RESULTS: Partial hepatectomy significantly impaired liver function according to conventional liver function tests as well as LiMAx in all groups. A mean of 4.10 ± 1.1 × 108 and 3.82 ± 0.7 × 108 hepatocytes were transplanted in groups 2 and 3, respectively. All animals remained stable with respect to vital parameters during and after HTx. The animals in group 2 showed enhanced liver regeneration as observed by mean postoperative LiMAx values (621.5 vs. 331.3 µg/kg/h on postoperative day 7; p < 0.001) whereas HTx in group 3 led to a significant increase in mean liver-specific coagulation factor VII (112.2 vs. 54.0% on postoperative day 7; p = 0.003) compared to controls (group 1), respectively. In both experimental groups, thrombotic material was observed in the portal veins and pulmonary arteries on histology, despite the absence of clinical symptoms. CONCLUSION: HTx can be performed safely and effectively immediately after a partial (50%) hepatectomy as well as 3 days postoperatively, with comparable results regarding the enhancement of liver function and regeneration.

[Complications and success rates of subclavian vein catheterization depending on experience]. / Komplikationen und Erfolgsraten des Vena-subclavia-Katheters in Abhängigkeit der Erfahrung.

BACKGROUND: The infraclavicular puncture of the subclavian vein is a standard procedure for anesthetists. Meanwhile the literature and recommendations are clear and the use of real-time ultrasound guidance is the standard procedure; however, anesthetists will always get into special circumstances were they have to use the landmark technique, so this competence must be preserved. Feared complications of infraclavicular subclavian vein puncture are pneumothorax and arterial puncture. Up to now there is no clear learning curve for the infraclavicular subclavian vein puncture in the landmark technique performed by anesthetists. OBJECTIVE: The aim of this study was to examine the influence of the puncture experience on the success rate and mechanical complications, such as pneumothorax and arterial puncture in patients who received an infraclavicular subclavian vein puncture with the landmark technique. Three levels of experience were defined for comparison: inexperienced 0-20 punctures, moderately experienced 21-50 and experienced over 50 punctures. MATERIAL AND METHODS: Post hoc analysis of a previously published noninferiority study to examine the influence of ventilation on the pneumothorax rate in the subclavian vein puncture using the landmark technique. This analysis included 1021 anesthetized patients who were included in the original study between August 2014 and October 2017. Demographic data as well as the number of puncture attempts, puncture success, the overall rate of mechanical complications, pneumothorax rate and arterial puncture rates were calculated. RESULTS: The overall rate of mechanical complications (pneumothorax + arterial puncture) was significantly higher in the inexperienced group (0-21) compared to the experienced group (>50, 15% vs. 8.5%, respectively, p = 0.023). This resulted in an odds ratio of 0.52 (confidence interval, CI: 0.32-0.85, p = 0.027). Likewise, the rate of puncture attempts in the group of inexperienced (0-20) with 1.85 ± 1.12 was significantly higher than in the group of experienced (>50, 1.58 ± 0.99, p = 0.004) and resulted in an odds ratio of 0.59 (CI: 0.31-0.96, p = 0.028). Although the puncture attempts of the moderately experienced (21-50) compared to the inexperienced (0-20) was not significant lower, we found an odds ratio of 0.69 (CI: 0.48-0.99, p = 0.042). The rate of successful puncture was 95.1% in the experienced group versus 89.3% in the inexperienced group (p = 0.001), which resulted in an odds ratio of 2.35 (CI: 1.28-4.31, p = 0.018). When viewed individually, no significant differences were found for pneumothorax and arterial puncture. CONCLUSION: In this post hoc analysis of the puncture of the subclavian vein using the landmark technique, we found a significant reduction of puncture attempts and overall mechanical complications. At least 50 punctures seem to be necessary to achieve the end of the learning curve; however, the landmark technique should only be used under special circumstances, when real-time ultrasound is not available. Anesthetists who want to complete their repertoire and learn the landmark technique should always perform a static ultrasound examination before starting the puncture in order to reduce complications due to anatomical variations or thrombosis.

Transfer of an interprofessional emergency caesarean section training program: using questionnaire combined with outcome data of newborn.

PUPROSE: An emergency caesarean section is a potentially life-threatening situation both for the mother and the newborn. Non-technical skills can be improved by simulation training and are necessary to manage this urgent situation successfully. The objective of this study was to investigate, if training of emergency caesarean section can be transferred into daily work to improve the outcome parameters pH an APGAR of the newborn. METHODS: In this pre-post study, 141 professionals took part in a training for emergency caesarean section. Participants received a questionnaire, based on the tools "Training Evaluation Inventory" and "Transfer Climate Questionnaire" 1 year after training. Outcome data of the newborn were collected from the hospitals information system. RESULTS: Except the scale "extinction", Cronbach's alpha was higher than 0.62. All scales were rated lower than 2.02 on a 5-point Likert Scale (1 = fullest approval; 5 = complete rejection). "Negative reinforcement" was rated with 2.87 (SD 0.73). There were no significant differences in outcome data prior. The questionnaire fulfils criteria for application except the scale "extinction". CONCLUSION: The presented training course was perceived as useful by the professionals and attitudes toward training were positive; the content was positively reinforced in practice 1 year after training. Parameters of the newborn did not change. It is conceivable that other outcome parameters (e.g. posttraumatic stress disorder) are addressed by the training. The development of relevant outcome parameters for the quality of emergency sections needs further investigation.

Changes of collective orientation through a medical student's anaesthesia simulation course - simulation-based training study with non-technical skills debriefing versus medical debriefing.

BACKGROUND: Non-technical skills (NTS) are known to have a positive impact on quality of medical care. The team performance enhancing behaviour, as an example for NTS, is termed "Collective Orientation" (CO). In this study, we investigated the effect of a simulator-based anaesthesia training upon student's CO in relation to medical and TeamGAINS (guided team self-correction, advocacy-inquiry and systemic-constructivist techniques) debriefing. We hypothesized (a) the scale collective orientation, as demonstrated in other team setting, is applicable to fourth year German medical students, (b) collective orientation increases by a four-hour anaesthesia simulation course, (c) the change in collective orientation can be influenced by type of debriefing. METHOD: All classes of an anaesthesia module (4th year medical students) were randomized into two groups. Students took part in a four-hour simulation course with team scenarios, supported by a simulated nurse. In group one the trainer focused on a debriefing on medical problems and in group two, a debriefing according to the specifications of the TeamGAINS concept was conducted. The primary outcome was the mean difference between the collective orientation measured (via questionnaires) immediately before (T1) and after (T2) training. RESULTS: Cronbach's alpha for all scales and measurement points was higher than 0.72. The scale "affiliation" decreases in the group medical debriefing MD = 0.1 (p = 0.008; r = 0.31) and was unchanged in the group TeamGAINS. "Dominance" increases in both groups. The values were MD = 0.19 (p = 0.003; r = 0.25) for medical debriefing and MD = 0.22 (p = 0.01; r = 0.40) for TeamGAINS debriefing. CONCLUSION: The collective orientation questionnaire can be applied to fourth year medical students. Simulation courses influence the attitude towards teamwork. The influence is negatively to the subscale "affiliation" by a "medical debriefing" and independently regardless of the nature of the debriefing for the subscale "dominance". We recommend a debriefing for medical students using the TeamGAINS approach to clarify the connection between the individual performance and non-technical skills. Anaesthesia simulation courses have the potential being a part of a longitudinal education curriculum for teaching non-technical skills.

[Care of Patients During Emergency Caesarian Section - Evaluation of Quality Characteristics from the Patients Point of View]. / Betreuung der Patientin während eines Notfallkaiserschnittes ­ Evaluation von Qualitätsmerkmalen aus Patientensicht.

BACKGROUND: An emergency caesarian section can be a terrifying experience for expectant mothers. Fear for her own life as well as her unborn child's is a traumatic event that can result in the development of post-traumatic stress disorder (PTSD). The aim of this survey was to define scales and items that describe the quality of care of parturients in cases of emergency caesarian section. METHODS: A pool of items was developed via a 2-step online Delphi survey administered to women who had undergone an emergency caesarian section. The resulting parameters were evaluated for relevance and validity in a larger patient collective. Lastly, we identified factors that could be grouped into relevant scales. RESULTS: After validating the results of the Delphi survey, 5 scales with 18 items were identified. They encompassed the following dimensions: "team external effect," "mother's level of information," "subjective evaluation," "personal integrity," and "after-care." These items could explain 58.2% of total variance and provide a stable factorial solution (KMO 0.76). CONCLUSION: To our knowledge, this is the first time a German criteria checklist has been developed to evaluate the care of expectant mothers undergoing an emergency caesarian section. This checklist can be used in addition to medical outcomes to measure quality of care. Further studies are needed to evaluate practical implementation and its impact on patient care.

Preoperative Recipient Parameters Allow Early Estimation of Postoperative Outcome and Intraoperative Transfusion Requirements in Liver Transplantation.

CONTEXT: Liver transplantation is a complex intervention, and early anticipation of personnel and logistic requirements is of great importance. Early identification of high-risk patients could prove useful. We therefore evaluated prognostic values of recipient parameters commonly available in the early preoperative stage regarding postoperative 30- and 90-day outcomes and intraoperative transfusion requirements in liver transplantation. DESIGN, SETTING, AND PARTICIPANTS: All adult patients undergoing first liver transplantation at Hannover Medical School between January 2005 and December 2010 were included in this retrospective study. Demographic, clinical, and laboratory data as well as clinical courses were recorded. Prognostic values regarding 30- and 90-day outcomes were evaluated by uni- and multivariate statistical tests. Identified risk parameters were used to calculate risk scores. RESULTS: There were 426 patients (40.4% female) included with a mean age of 48.6 (11.9) years. Absolute 30-day mortality rate was 9.9%, and absolute 90-day mortality rate was 13.4%. Preoperative leukocyte count >5200/µL, platelet count <91 000/µL, and creatinine values ≥77 µmol/L were relevant risk factors for both observation periods ( P < .05, respectively). A score based on these factors significantly differentiated between groups of varying postoperative outcomes and intraoperative transfusion requirements ( P < .05, respectively). CONCLUSION: A score based on preoperative creatinine, leukocyte, and platelet values allowed early estimation of postoperative 30- and 90-day outcomes and intraoperative transfusion requirements in liver transplantation. Results might help to improve timely logistic and personal strategies.

["Learning in Protected Environment"- Implementation in Continuing Medical Education]. / "Lernen im geschützten Umfeld": Implementierung in die Fort- und Weiterbildung.

Actual concepts in continuing medical education in acute or emergency medicine contain skill training as well as simulation training. Methods and mechanisms to reduce crisis, like human factor training, shared mental models or closed-loop communication are incorporated. It is unknown which training method is optimal for individual departments in hospitals or for the individual level of education of the healthcare provider. A concept we provide is the so called "learning in protected environment": this environment protects the course participants and our patients from negative consequences of a conventional hands-on training. Concurrently the participants benefit from our standardized course concepts. We achieve our goal of an optimal preparation for clinical practice by continuous re-evaluation of the content and educational objects. The implementation of a multimodal team training has to be adopted for each institution individually - methods for an implementation should be standardized. We suggest the use of the "Kern cycle" for a structured approach to curriculum development. On this foundation the combination of "learning in protected environment" and crisis training is optimal to achieve an improved patient safety in acute care.

[Simulation as a Training Method for the Professionalization of Teams]. / Simulation als Fortbildungsmethode zur Professionalisierung von Teams.

Simulation as an educational method can be applied to the training of processes, technical and non-technical skills. This article focuses on the role of simulation in crisis resource management and non-technical skills. A realistic work environment requires well-trained staff regarding simulation technology and communication. A training (unit) is divided into three sections. During the briefing the team is introduced to the scenario. Afterwards, the patient is treated by an interdisciplinary team. Communication under the pressure of action, even if one does not agree with the approach of the colleagues, should be practiced. After the scenario a structured debriefing is conducted. The trainer supervises the reflection of the teams' actions. Various methods such as "guided team self-correction", "advocacy-inquiry" and the "TeamGAINS"-approach are available for this decisive phase of the training. A safe environment is guaranteed, video recordings will never leave the training. Active experimentation, concrete experiences and accurate reflection are the key factors of success for the method simulation. Positive effects on critical incidents, resuscitation outcome and improvement of team climate can be observed after simulation training.

Simulator-Based Air Medical Training Program Christoph Life: From Concept to Course.

OBJECTIVE: Christoph Life is a simulator-based air medical training program and a new and innovative educational concept. Participants pass different scenarios with a fully equipped and movable helicopter simulator. Main focuses of the program are crew resource management (CRM) elements and team training. Information about expectations end effectiveness of the training is sparse. METHODS: During a 2-day training, participants learn CRM basics and complete various emergency medical scenarios. For evaluation, we used an anonymous questionnaire either with polar questions or a 6-coded psychometric Likert scale. The Wilcoxon test was used for statistical analysis. The significance level was set at P < .05. RESULTS: Thirteen teams of emergency physicians and specially trained paramedics underwent Christoph Life. It was evaluated largely positively and considered very helpful for daily work (5.7 ± 0.5) and avoiding mistakes (5.7 ± 0.5). The quality of participants' knowledge about CRM basics (3.5 ± 1.2 vs. 5.4 ± 0.7, P < .001), self-assessment of communication skills (4.2 ± 0.7 vs. 4.8 ± 0.8, P = .02), and active reflection of communication aspects (3.9 ± 0.9 vs. 5.5 ± 0.5, P < .001) could be strikingly increased. CONCLUSIONS: There is a considerable demand for intensified training on the part of the users. We were able to show that a simulator-based air medical training program is a helpful training tool with an obvious subjective benefit for the participants' nontechnical skills.

[Development of a competence catalogue for physicians in training for curriculum creation with respect to delivery room training]. / Entwicklung eines Kompetenzkatalogs für Ärzt:Innen in Weiterbildung zur Curriculumerstellung für die Kreißsaaleinarbeitung.

BACKGROUND: Anesthesiologic expertise is used at various points in the delivery room. The natural turnover of professionals requires continuous education and training for patient care. In a first survey among consultants and trainees, the desire for a delivery room-specific anesthesiologic curriculum has emerged. In order to enable a curriculum with decreasing supervision, a competence-oriented catalogue is used in many medical fields. The gain in competence develops gradually. The participation of practitioners should be obligatory to avoid a differentiation between theory and practice. The structural framework of curriculum development by Kern et al. provides the learning objective analysis after further evaluation. In the sense of specific learning objective definition, the present study aims to describe the competences for anesthetists in the delivery room. METHODS: An expert group (active in the anesthesiology delivery room environment) developed a set of items via a two-step online Delphi survey. The experts were recruited from the German Society for Anesthesiology and Intensive Care Medicine (DGAI). We evaluated the resulting parameters for relevance and validity in a larger collective. Lastly, we used factorial analyses to identify factors that could be used to group items into relevant scales. In total, 201 participants took part in the final validation survey. RESULTS: During the prioritization process of Delphi analyses, competencies such as neonatal care were not followed up. Not all items developed are exclusively delivery room-related, such as managing a difficult airway. Other items are specific to the environment of obstetrics. One example is integration of spinal anesthesia into the obstetric context. Some items are exclusively related to the delivery room, such as in-house standards of care in obstetrics as a basic skill. After validation, a competence catalogue with 8 scales with a total of 44 competence items resulted (Kayser-Meyer-Olkin criterion 0.88). CONCLUSION: A catalogue of relevant learning objectives for anesthetists in training could be developed. It specifies the generally required content of anesthesiologic training in Germany. Specific patient groups, such as patients with congenital heart defects, are not mapped. Competencies that could also be learned outside the delivery room, should be learned before the rotation. This enables the focus on the delivery room items, especially for those to be trained who do not work in a hospital with obstetrics. The catalogue needs to be revised for completeness for its own working environment. Particularly in hospitals that do not have a pediatrician available, neonatal care becomes significant. Didactic methods, such as entrustable professional activities, have to be tested and evaluated. These enable competence-based learning with decreasing supervision and reflect the reality in hospitals. As not every clinic can provide the necessary resources for this a nationwide provision of documents would be helpful.

Further development of crew resource management training : Needs assessment by means of teamwork-context analysis in anesthesia and intensive care teams.

BACKGROUND: Teams in anesthesia and intensive care work as high responsibility teams (HRT). Success in this environment partly depends on the use of nontechnical skills which can be learned through simulation-based training. A teamwork context analysis could help to identify training requirements for crew resource management training. MATERIAL AND METHODS: We used a multicentric observational cross-sectional study design utilizing survey methodology to evaluate the teamwork context of different work environments, using the 62-item TAKAI inventory. We surveyed anesthesia and intensive care staff from nine hospitals in Germany which provide varying levels of care. RESULTS: In total, 128 people (44.5% male, 53.9% female) from 9 German hospitals participated in the study. The topics "interconnectedness: departments", "interconnectedness: information flow", "dynamics", "polytely", "velocity of the team's movement", "velocity of system changes", "hierarchy" and "hierarchy: leadership", "shared task mental model", "shared team mental model" and all aspects of the scale "adaptive behaviors" were identified as focal aspects to be implemented into Crew-Resource-Management (CRM) training for the evaluated work environments. CONCLUSION: The TAKAI scales meet quality criteria (Cronbach's alpha > 0.6) and are appropriate for use in the analysis of the teamwork environment. The results indicate many similarities between the work contexts surveyed but also slight differences. TAKAI can be an additional method to design an appropriate simulation training program for HRT in anesthesia and intensive care medicine as there does not seem to be a one-size-fits-all simulation concept. For a special focus on the needs of a work context, the easy to perform TAKAI analysis in the needs analysis step is worthwhile.

[Analyses of requirements for curriculum development for the training of anesthesiologists in the delivery room-A nationwide survey]. / Bedarfsanalyse zur Curriculumsentwicklung für die anästhesiologische Kreißsaalversorgung ­ eine deutschlandweite Umfrage.

BACKGROUND: Anesthesiologic activity in the delivery room environment implies the specifics of a 200% lethality, which describes that emergency situations can affect mother and child. A circumstance that impressively underlines the need for special care in employee training and selection. The training situation in the delivery room is characterized by several difficulties. Technical procedures are often performed on the awake patient, who is herself in an exciting situation during childbirth. A detailed description of the necessary competences in this working environment does not exist at the present. The present study aims to describe the further education situation in anesthesiology. The results can represent the first step of a curriculum development according to the concept of Kern et al. in the sense of a needs assessment. MATERIAL AND METHODS: In a multicenter observational study, doctors in further training (AiW) and consultants (FÄ) were asked about methods of familiarization, feedback, activities taken on and the need for a curriculum. The level of supervision and confidence in action during procedures was also elicited. Participants were contacted via the membership database of the German Society of Anesthesia and Intensive Care and could answer the 11-item questionnaire online. RESULTS: A total of 495 questionnaires (329 FÄ; 166 AiW;) were completed. The FÄ and AiW gave different information on the conduct of exit interviews (59.6% vs. 10%) and curriculum support (76.3% vs.17.5%). Independent of the year of training, AiWs perform cesarean sections under on-demand (reactive) supervision. Peridural anesthesia (PDA) is the least frequently performed procedure in the context of the familiarization situation with obstetric anesthesia. The groups have a different confidence of security in the successful implementation of procedures, when AiW are proceeding without direct supervision (FÄ = MD 61; AiW = MD 77; p < 0.001; scale 0 = unsecure-100 = very secure). Practical and technical support is mostly provided immediately by FÄ (> MW 91; scale 0 = never-100 = immediately). Individual values deviate significantly from the average values (outliers). Both groups rate the usefulness or value of describing learning objectives and the availability of a curriculum as high. DISCUSSION: The support of familiarization and continuing support is partly answered differently by consultants and doctors in further training. Individual procedures that are rarely performed, such as administration of a PDA, require special attention in the future. Curricula with workplace-based assessments could provide feedback and assurance to increase confidence in the successful implementation of procedures by AiW. The AiW usually receive immediate professional support. Individual institutions do not seem to have any concepts here and must rethink their processes. This fact is particularly important against the background of the medicolegal significance of the subject. The description of learning objectives and curriculum development is desired both by FÄ and AiW.

Porcine Liver Transplantation Without Veno-venous Bypass As an Extended Criteria Donor Model.

Liver transplantation is regarded as the gold standard for the treatment of a variety of fatal hepatic diseases. However, unsolved issues of chronic graft failure, ongoing organ donor shortages, and the increased use of marginal grafts call for the improvement of current concepts, such as the implementation of organ machine perfusion. In order to evaluate new methods of graft reconditioning and modulation, translational models are required. With respect to anatomical and physiological similarities to humans and recent progress in the field of xenotransplantation, pigs have become the main large animal species used in transplantation models. After the initial introduction of a porcine orthotopic liver transplant model by Garnier et al. in 1965, several modifications have been published over the past 60 years. Due to specifies-specific anatomical traits, a veno-venous bypass during the anhepatic phase is regarded as a necessity to reduce intestinal congestion and ischemia resulting in hemodynamic instability and perioperative mortality. However, the implementation of a bypass increases the technical and logistical complexity of the procedure. Furthermore, associated complications such as air embolism, hemorrhage, and the need for a simultaneous splenectomy have been reported previously. In this protocol, we describe a model of porcine orthotopic liver transplantation without the use of a veno-venous bypass. The engraftment of donor livers after static cold storage of 20 h - simulating extended criteria donor conditions - demonstrates that this simplified approach can be performed without significant hemodynamic alterations or intraoperative mortality and with regular uptake of liver function (as defined by bile production and liver-specific CYP1A2 metabolism). The success of this approach is ensured by an optimized surgical technique and a sophisticated anesthesiologic volume and vasopressor management. This model should be of special interest for workgroups focusing on the immediate postoperative course, ischemia-reperfusion injury, associated immunological mechanisms, and the reconditioning of extended criteria donor organs.
