[Further Development of Maturity Levels of Quality and Risk Management System at the University Hospital Schleswig-Holstein]. / Weiterentwicklung der Reifegrade des Qualitäts ­ und Risikomanagementsystems am Universitätsklinikum Schleswig-Holstein.

INTRODUCTION: Following upon our publication "Maturity Levels of Quality and Risk Management at the University Hospital Schleswig-Holstein" in 2018, we present the further development of the maturity model. Quality and risk management in hospitals is not only required by law but also plays a significant role in an optimized patient- and process-oriented health care. METHODS: A questionnaire-based self-assessment was carried out by 46 clinical units of the UKSH (location Kiel and Lübeck) for the analysis of nine quality criteria overall. Four of these criteria (quality assurance (QS), critical incident reporting system (CIRS), complaint management (BM) and process management (PM)) were already analysed in 2016 and were extended to the five new aspects, namely audits and on-site inspections, responsibilities, morbidity and mortality conferences, hygiene training and surgical safety checklist. Every quality item was graded into four categories from "A" (fully implemented) to "D" (not implemented at all). RESULTS: The comparison of the results for quality criteria QS, CIRS, BM, PM and the overall maturity level between 2016 and 2020 demonstrated statistically significant improvements in 2020 concerning the criteria QS (p=0.013), CIRS (p=0.026), PM (p=0.000) and the overall maturity levels (p=0.019). The criteria BM did not show any statistically significant improvement. The five newly added quality criteria demonstrated maturity levels "A" (fully implemented) and "B" (largely implemented) the following: audits and on-site inspections (100%), responsibilities (95.6%), morbidity and mortality conferences (65.2%), hygiene training (95.6%), and surgical safety checklist (100%). CONCLUSION: An integrated quality and risk management has already been a firm element of UKSH for years. Nevertheless, review of effectiveness of the initiated targeted measures is still a challenge. This is the reason why it is necessary to develop effective and resource-saving approaches for the evaluation of measures and the identification of potential for improvement. The recognised potential for improvement should be risk-prioritized and completely exploited using sustainable measures. Following this principle, we designed a qualitative model of maturity levels for the evaluation of our quality and risk management system at the UKSH in 2016, whose further development we demonstrate here.

Application of mechanical cardiopulmonary resuscitation devices and their value in out-of-hospital cardiac arrest: A retrospective analysis of the German Resuscitation Registry.

BACKGROUND: Cardiac arrest is an event with a limited prognosis which has not substantially changed since the first description of cardiopulmonary resuscitation (CPR) in 1960. A promising new treatment approach may be mechanical CPR devices (mechanical CPR). METHODS: In a retrospective analysis of the German Resuscitation Registry between 2007-2014, we examined the outcome after using mechanical CPR on return of spontaneous circulation (ROSC) in adults with out-of-hospital cardiac arrest (OHCA). We compared mechanical CPR to manual CPR. According to preclinical risk factors, we calculated the predicted ROSC-after-cardiac-arrest (RACA) score for each group and compared it to the rate of ROSC observed. Using multivariate analysis, we adjusted the influence of the devices' application on ROSC for epidemiological factors and therapeutic measures. RESULTS: We included 19,609 patients in the study. ROSC was achieved in 51.5% of the mechanical CPR group (95%-CI 48.2-54.8%, ROSC expected 42.5%) and in 41.2% in the manual CPR group (95%-CI 40.4-41.9%, ROSC expected 39.2%). After multivariate adjustment, mechanical CPR was found to be an independent predictor of ROSC (OR 1.77; 95%-CI 1.48-2.12). Duration of CPR is a key determinant for achieving ROSC. CONCLUSIONS: Mechanical CPR was associated with an increased rate of ROSC and when adjusted for risk factors appeared advantageous over manual CPR. Mechanical CPR devices may increase survival and should be considered in particular circumstances according to a physicians' decision, especially during prolonged resuscitation.

[Maturity Levels of Quality and Risk Management at the University Hospital Schleswig-Holstein]. / Reifegrade des Qualitäts- und Risikomanagementsystems am Universitätsklinikum Schleswig-Holstein.

INTRODUCTION: Quality and risk management in hospitals are not only required by law but also for an optimal patient-centered and process-optimized patient care. To evaluate the maturity levels of quality and risk management at the University Hospital Schleswig-Holstein (UKSH), a structured analytical tool was developed for easy and efficient application. METHODS: Four criteria concerning quality management - quality assurance (QS), critical incident reporting system (CIRS), complaint management (BM) and process management (PM) - were evaluated with a structured questionnaire. Self-assessment and external assessment were performed to classify the maturity levels at the UKSH (location Kiel and Lübeck). Every quality item was graded into four categories from "A" (fully implemented) to "D" (not implemented at all). First of all, an external assessment was initiated by the head of the department of quality and risk management. Thereafter, a self-assessment was performed by 46 clinical units of the UKSH. Discrepancies were resolved in a collegial dialogue. Based on these data, overall maturity levels were obtained for every clinical unit. RESULTS: The overall maturity level "A" was reached by three out of 46 (6.5%) clinical units. No unit was graded with maturity level "D". 50% out of all units reached level "B" and 43.5% level "C". The distribution of the four different quality criteria revealed a good implementation of complaint management (maturity levels "A" and "B" in 78.3%), whereas the levels for CIRS were "C" and "D" in 73.9%. Quality assurance and process management showed quite similar distributions for the levels of maturity "B" and "C" (87% QS; 91% PM). DISCUSSION: The structured analytical tool revealed maturity levels of 46 clinical units of the UKSH and defined the maturity levels of four relevant quality criteria (QS, CIRS, BM, PM). As a consequence, extensive procedures were implemented to raise the standard of quality and risk management. In future, maturity levels will be reevaluated every two years. This qualitative maturity level model enables in a simple and efficient way precise statements concerning presence, manifestation and development of quality and risk management.

The antibiotic resistome and microbiota landscape of refugees from Syria, Iraq and Afghanistan in Germany.

BACKGROUND: Multidrug-resistant bacteria represent a substantial global burden for human health, potentially fuelled by migration waves: in 2015, 476,649 refugees applied for asylum in Germany mostly as a result of the Syrian crisis. In Arabic countries, multiresistant bacteria cause significant problems for healthcare systems. Currently, no data exist describing antibiotic resistances in healthy refugees. Here, we assess the microbial landscape and presence of antibiotic resistance genes (ARGs) in refugees and German controls. To achieve this, a systematic study was conducted in 500 consecutive refugees, mainly from Syria, Iraq, and Afghanistan and 100 German controls. Stool samples were subjected to PCR-based quantification of 42 most relevant ARGs, 16S ribosomal RNA gene sequencing-based microbiota analysis, and culture-based validation of multidrug-resistant microorganisms. RESULTS: The fecal microbiota of refugees is substantially different from that of resident Germans. Three categories of resistance profiles were found: (i) ARGs independent of geographic origin of individuals comprising BIL/LAT/CMA, ErmB, and mefE; (ii) vanB with a high prevalence in Germany; and (iii) ARGs showing substantially increased prevalences in refugees comprising CTX-M group 1, SHV, vanC1, OXA-1, and QnrB. The majority of refugees carried five or more ARGs while the majority of German controls carried three or less ARGs, although the observed ARGs occurred independent of signatures of potential pathogens. CONCLUSIONS: Our results, for the first time, assess antibiotic resistance genes in refugees and demonstrate a substantially increased prevalence for most resistances compared to German controls. The antibiotic resistome in refugees may thus require particular attention in the healthcare system of host countries.

Evidence and consensus based guideline for the management of delirium, analgesia, and sedation in intensive care medicine. Revision 2015 (DAS-Guideline 2015) - short version.

In 2010, under the guidance of the DGAI (German Society of Anaesthesiology and Intensive Care Medicine) and DIVI (German Interdisciplinary Association for Intensive Care and Emergency Medicine), twelve German medical societies published the "Evidence- and Consensus-based Guidelines on the Management of Analgesia, Sedation and Delirium in Intensive Care". Since then, several new studies and publications have considerably increased the body of evidence, including the new recommendations from the American College of Critical Care Medicine (ACCM) in conjunction with Society of Critical Care Medicine (SCCM) and American Society of Health-System Pharmacists (ASHP) from 2013. For this update, a major restructuring and extension of the guidelines were needed in order to cover new aspects of treatment, such as sleep and anxiety management. The literature was systematically searched and evaluated using the criteria of the Oxford Center of Evidence Based Medicine. The body of evidence used to formulate these recommendations was reviewed and approved by representatives of 17 national societies. Three grades of recommendation were used as follows: Grade "A" (strong recommendation), Grade "B" (recommendation) and Grade "0" (open recommendation). The result is a comprehensive, interdisciplinary, evidence and consensus-based set of level 3 guidelines. This publication was designed for all ICU professionals, and takes into account all critically ill patient populations. It represents a guide to symptom-oriented prevention, diagnosis, and treatment of delirium, anxiety, stress, and protocol-based analgesia, sedation, and sleep-management in intensive care medicine.

Difficult intubation and outcome after out-of-hospital cardiac arrest: a registry-based analysis.

BACKGROUND: Airway management during resuscitation attempts is pivotal for treating hypoxia, and endotracheal intubation is the standard procedure. This German Resuscitation Registry analysis investigates the influence of airway management on primary outcomes after out-of-hospital cardiac arrest, in a physician-based emergency system. METHODS: A total of 8512 patients recorded in the German Resuscitation Registry (2007-2011) were analyzed. The Return of Spontaneous Circulation After Cardiac Arrest (RACA) score was used to compare observed return of spontaneous circulation (ROSC) rates with the ROSC predicted by the score and to analyze factors influencing the primary outcome. Patients were classified into three groups: difficult intubation, impossible intubation, and a control group with normal airways. RESULTS: The observed ROSC matched the predicted ROSC in the group with difficult airways. The impossible intubation group had lower ROSC rates (31.3% vs. 40.5%; P < 0.05). Impossible intubation was more frequent in men (OR 2.28; 95% CI, 1.43-3.63; P = 0.001), young patients (OR 2.18; 95% CI, 1.26-3.76; P = 0.005) and those with trauma (OR 2.22; 95% CI, 1.01-4.85; P = 0.046). Fewer impossible intubations were reported when the emergency physicians were anesthesiologists (OR 0.65; 95% CI, 0.44-0.96; P = 0.028). If a supraglottic airway device was not used in the impossible intubation group, the observed ROSC (18.0%; 95% CI, 7.4-28.6%) was poorer than predicted (38.2%) (P < 0.05). CONCLUSIONS: Outcomes after resuscitation attempts are poorer when endotracheal intubation is not possible. Predictive factors for impossible intubation are male gender, younger age, and trauma. Supraglottic airway devices should be used at an early stage whenever these negative factors are present.

Profiling of cell stress protein expression in cardiac tissue of cardiosurgical patients undergoing remote ischemic preconditioning: implications for thioredoxin in cardioprotection.

BACKGROUND: Transient episodes of ischemia in a remote organ (remote ischemic preconditioning, RIPC) can attenuate myocardial ischemia/reperfusion injury but the underlying mechanisms of RIPC in the target organ are still poorly understood. Recent animal studies suggested that the small redox protein thioredoxin may be a potential candidate for preconditioning-induced organprotection. Here we employed a human proteome profiler array to investigate the RIPC regulated expression of cell stress proteins and particularly of thioredoxin in heart tissue of cardiosurgical patients with cardiopulmonary bypass (CPB). METHODS: RIPC was induced by four 5 minute cycles of transient upper limb ischemia/reperfusion using a blood pressure cuff. Right atrial tissue was obtained from patients receiving RIPC (N = 19) and control patients (N = 19) before and after CPB. Cell stress proteome profiler arrays as well as Westernblotting and ELISA experiments for thioredoxin (Thio-1) were performed employing the respective tissue samples. RESULTS: Protein arrays revealed an up-regulation of 26.9% (7/26; CA IX, Cyt C, HSP-60, HSP-70, pJNK, SOD2, Thio-1) of cell stress associated proteins in RIPC tissue obtained before CPB, while 3.8% (1/26; SIRT2) of the proteins were down-regulated. Array results for thioredoxin were verified by semi-quantitative Westernblotting studies which showed a significant up-regulation of thioredoxin protein levels in cardiac tissue samples of RIPC patients taken before CPB (RIPC: 5.36 ± 0.85 a.u.; control: 3.23 ± 0.39 a.u.; P < 0.05). Quantification of thioredoxin levels in tissue of RIPC and control patients by ELISA experiments further confirmed the Westernblotting results (RIPC: 0.30 ± 0.02 ng/mg protein; control: 0.24 ± 0.02 ng/mg protein; P < 0.05). CONCLUSION: We provide evidence for thioredoxin as a RIPC-induced factor in heart tissue of cardiosurgical patients and identified several cell stress associated proteins that are regulated by RIPC and may play a role in RIPC-mediated cardioprotection.
