Genomic epidemiology of clinical ESBL-producing Enterobacteriaceae in a German hospital suggests infections are primarily community- and regionally-acquired.

Clinical Enterobacteriaceae isolates that produce extended-spectrum β-lactamases (ESBLs) have been increasingly reported at a global scale. However, comprehensive data on the molecular epidemiology of ESBL-producing strains are limited and few studies have been conducted in non-outbreak situations.We used whole-genome sequencing to describe the population structure of 294 ESBL-producing Escherichia coli and Klebsiella pneumoniae isolates that were recovered from a German community hospital throughout a 1 year sampling period in a non-outbreak situation.We found a high proportion of E. coli isolates (61.5 %) belonged to the globally disseminated extraintestinal pathogenic ST131, whereas a wider diversity of STs was observed among K. pneumoniae isolates. The E. coli ST131 population in this study was shaped by multiple introductions of strains as demonstrated by contextual genomic analysis including ST131 strains from other geographical sources. While no recent common ancestor of the isolates of the current study and other international isolates was found, our clinical isolates clustered with those previously recovered in the region. Furthermore, we found that the isolation of ESBL-producing clinical strains in hospitalized patients could only rarely be associated with likely patient-to-patient transmission, indicating primarily a community and regional acquisition of strains.Further genomic analyses of clinical, carriage and environmental isolates is needed to uncover hidden transmissions and thus discover the most common sources of ESBL-producing pathogen infections in our hospitals.

Diabetes-associated nephropathy and obesity influence COVID-19 outcome in type 2 diabetes patients

ABSTRACT Coronavirus disease 2019 has rapidly spread around the globe and various comorbidities, such as diabetes have been recognized as risk factors for an unfavorable outcome. We analyzed a cohort of COVID-19 patients (n = 75) treated at a German community hospital. With a focus on diabetes mellitus, we evaluated the impact of distinct comorbidities on the COVID-19 disease course. The duration of hospital stay was prolonged if diabetes was present. An older age was associated with a poor outcome. The percentage of non-survivors increased in the presence of congestive heart failure or chronic kidney disease. In the group of diabetes patients, mortality was increased if any organ complication was present and diabetic nephropathy or the combination of obesity plus diabetes were by far the most important risk factors. Taken together, an older age, congestive heart failure, and chronic kidney disease significantly influenced COVID-19 disease course and survival. Diabetic nephropathy or the combination of obesity plus diabetes had the strongest impact on patients’ outcome.

Coronavirus disease (COVID-19): observations and lessons from primary medical care at a German community hospital

ABSTRACT The pandemic outbreak of COVID-19 challenges medical care systems all around the world. We here describe our experiences during the treatment of COVID-19 patients (n = 42) treated from 2 March 2020 to 16 April 2020 at a German district hospital. Forty-two COVID-19 patients were hospitalized and five patients developed a severe disease, requiring intensive care. Overall, 11 out of 42 hospitalized patients died. COVID-19 caused lymphocytopenia, as well as increased d-dimer, c-reactive protein and creatine kinase, and lactate dehydrogenase levels. These changes were mostly pronounced in patients that developed a severe disease course. Radiologic findings included ground-glass opacity, bilateral/multilobular involvement, consolidation, and posterior involvement. We compared COVID-19 patients to an average population of ‘non-COVID’ patients. Interestingly, no laboratory or radiologic finding was specific for COVID-19 when standing alone, as comorbidities of ‘non-COVID’ patients certainly can mimic similar results. In common praxis, the diagnosis of COVID-19 is based on a positive PCR result. However, a false-negative result causes problems for the workflow of an entire hospital. In our clinic, the consequences of a false assumption of SARS-CoV-2 negativity in four cases had dramatic consequences, as contact persons had to be quarantined. To avoid this, a comprehensive view of lab-results, radiology, clinical symptoms and comorbidities is necessary for the correct diagnosis or exclusion of COVID-19.

Thrombolysis management in thrombectomy patients: Real-life data from German stroke centres.

In randomised clinical trials (RCTs), endovascular thrombectomy (ET) was combined with intravenous thrombolysis (IVT) in the vast majority of patients. We aimed to analyse how German stroke centres manage IVT in patients receiving ET in daily routine. We performed an online survey among neurologists and neurointerventionalists that included all German University hospitals and a selection of German community hospitals known to perform ET. The survey consisted of 20 questions and was open for reply from 20 December 2016 to 9 January 2017. Overall, there were 110 replies, 76% (84/110) from neurologists and 20% (22/110) from neurointerventionalists. The majority of participants (75/99, 76%) reported to continue IVT after start of ET. Nine participants (9%) reported to stop IVT as a standard of care before ET and another 15 (15%) reported to stop IVT on a case-by-case basis. Thrombolysis is given intra-arterially in individual cases in 39% (37/99) and as a standard of care in 3% (3/99). Intra-arterial Heparin is given additionally as a standard procedure in 25% (24/96) and in individual cases in 11% (11/96). IVT is omitted even without contraindications before ET in 5% (5/95) as standard procedure and in 14% (13/95) in individual cases. We observed a wide heterogeneity with respect to the management of IVT in the context of ET. Evidence from RCTs is not implemented in a large number of cases. These findings emphasise a requirement for further education and implementation of standards for the management of intravenous thrombolysis in endovascular treated stroke patients.

Associations of work characteristics, employee strain and self-perceived quality of care in Emergency Departments: A cross-sectional study

BackgroundThe individual and shared effects of adverse work characteristics on patient care in Emergency Departments (ED) are yet not well understood. We investigated the associations of self-reported ED work characteristics, work-related strain, and perceived quality of care. MethodsQuestionnaire-based survey with standardized measures among N=53 ED professionals (i.e., nurses, physicians, and administration staff). The study was conducted in the interdisciplinary ED of a German community hospital. ResultsA high prevalence of work-related strain was observed: 66.0% of ED professionals showed high levels of emotional exhaustion and 55.6% showed irritation scores above the cut-off value. ED staff reported high supervisor support and autonomy, paired with high time pressure and patient-related stressors. Multivariate analyses revealed that high time pressure and low supervisor support were associated with high work-related strain. Low staffing was related to inferior quality of ED care. ConclusionsED work systems involve high competing demands for ED professionals with substantial risks for work-related strain. Moreover, adverse ED work characteristics comprise risks for high quality patient care. Our results suggest that promoting work characteristics might foster ED staff functioning on the job as well as improve ED patient care.

Treatment of status epilepticus in a large community hospital

BackgroundStatus epilepticus (SE) is a neurological emergency usually requiring immediate medical treatment. Due to the lack of adequate studies, treatment guidelines and their application vary between countries and institutions. We intended to analyze current treatment of SE in a German community hospital. MethodsWe retrospectively identified patients from a large community hospital in northern Germany who had been diagnosed with SE between August 2008 and December 2010. Their charts were reviewed regarding sociodemographic variables, treatment and outcome. ResultsWe studied the first SE episode in 172 patients with a median age of 69years (range 18–90years). The etiology was acute symptomatic in 30 patients, progressive symptomatic in 22 patients and remote symptomatic in 120 patients. Presentation was generalized convulsive in 60 patients, non-convulsive in 72 patients and simple motor/aura in 40 patients. Median latency from onset to treatment start was 0.75h (range 0.2–336h). Initial treatment had a success rate (SR) of 40%. Second line treatment had a success rate of 54%. In patients whose seizures were refractory to the first two drugs, success rates were between 31% and 55%, with only a minority of the patients receiving established drugs such as phenytoin or barbiturates.Multivariate analysis revealed non-convulsive semiology as the only factor significantly associated with refractoriness. SE could be terminated in 95% of the patients and in-hospital mortality was 10%. Benzodiazepines and phenytoin had the most severe side effects. ConclusionsStatus epilepticus can be terminated successfully and with low in-hospital mortality in the vast majority of the patients treated in a large community hospital. The success rate of each treatment step is between 30% and 55% regardless of the substances used.

High-sensitive troponin T measurement for patients with acute chest pain: improvement of diagnostics?

Highly precise laboratory methods have been developed to determine cardiac troponin levels (cTn) according to the universal definition of acute myocardial infarction (MI). We examined the impact of lowering the level of detection of cTn measurement in consecutive patients presenting to the emergency department (ED) of a large German community hospital.

Lower Respiratory Tract Disease in Children: Constant Pathogens – Constant Management?!

This study analyses the pathogens of acute lower respiratory tract infections (LRI) in children in a German community hospital over six years. Against this background the adoption of new diagnostic and therapeutic guidelines for the LRI management and of RSV-cases in particular is studied. 1054 children aged zero to 36 months hospitalized with LRI were prospectively included in the surveillance studies "Parainfluenzavirus (PIV) and Respiratory syncytial virus (RSV) infections in Germany [PRI.de] 1999-2001" and the "pediatric infectious diseases network on acute respiratory tract infections" [PID-ARI.net] for the time period of October 2002 until June 2005. The nasopharyngeal aspirates (NPA) of these children had been analysed for RSV, PIV 1,2,3 and influenzavirus (IV)-A, -B. In 2003/2004 the national guideline on how to diagnose and treat RSV-disease (bronchiolitis) changed. Data on LRI cases severity and especially those regarding the clinical management of RSV-infections were compared to see differences following the release of the guideline. 84% of the children were between zero and 24 months old. 34% of the NPA specimens were positive for RSV, 7.7% for PIV 1,2,3 and 4.7% for IV-A, -B. Epidemiological findings did not differ substantially between the two studies. Clinical management of RSV-LRI, especially drug use, did not change except for the lower rate of x-ray examination (p<0.01). The spectrum of causing agents in LRI of children remained quite stable over of six years. Diagnostic and therapeutic concepts remain also stable in a situation where new guidelines were introduced, but not reinforced.

Laparoscopic live donor nephrectomy for right kidneys: Experience in a German community hospital

Laparoscopic live donor nephrectomy has become the new gold standard for kidney procurement in many high-volume transplant centres worldwide, but it is often limited to left-sided donor kidneys. Concerns about adequate anatomical renal vessel length and sufficient surgical exposure are the main obstacles to the use of the laparoscopic approach for right kidney live donors as well. From 1998 to 2006 we performed laparoscopic kidney procurement in 73 live kidney donors on an intention-to-treat basis, harvesting a total of 48 left (LKG) and 25 right kidneys (RKG) for transplantation. We compared these two groups with respect to operating time, conversion rate, complications, hospital stay, and recipient outcome. There were no differences in outcome of donor patients after left (D-LKG) or right laparoscopic donor nephrectomy (D-RKG). Operating time was 160 min in D-RKG versus 164 min in D-LKG. Warm ischemia was below 150 s in both groups. Hospital stay was 7.0 (D-RKG) versus 6.7 days (D-LKG). Negative events on the donor site were one temporary nerve irritation in each group and one postoperative retroperitoneal hematoma in the left kidney group. Reasons to convert to open nephrectomy were bleeding in two patients in the left kidney group and adhesions in one patient in the right kidney group. The outcome of the recipients after left (R-LKG) or right kidney (R-RKG) transplantation was similar. One kidney was lost due to renal vein thrombosis (R-LKG). Postoperative ureter complications occurred in one patient of each group. One patient of the R-RKG and two patients of the R-LKG required lymphocele fenestration. All other kidney transplants worked without problems. Laparoscopic donor nephrectomy is a safe procedure and has been established as the method of choice for live kidney donation in our clinic. Laparoscopic procurement of right and left kidneys can be performed with comparable quality and outcome for donors and recipients.

Early results of coronary angioplasty despite more complex interventions (Registry of The German Community Hospitals 1993–2000)

The registry of the German community hospitals has recorded all percutaneous coronary interventions (PCIs) of 85 participating centers since October 1992. 1 Vogt A. Bonzel T. Harmjanz D. von Leitner E.R. Pfafferott C. Engel H.J. Niederer W. Schuster P.R. Glunz H.G. Neuhaus K.L. PTCA registry of the German community hospitals. Eur Heart J. 1997; 18: 1110-1114 Crossref PubMed Scopus (63) Google Scholar This registry gives the opportunity to show trends in the profile of the patients and the performance of the procedures. The present report is on all procedures from 1993 to 2000, including all entries with complete hospital discharge forms. These forms were completed in 94.4% of all interventions, and the registry represents approximately 1/4 of all PCI procedures in Germany.

Elective Coronary Stenting as an Adjunct to Balloon Angioplasty in Stable Coronary Artery Disease: No Association with Incidence of Acute Complications. Results of the PTCA Registry of the German Community Hospitals

Background: Elective coronary stenting has hem shown to reduce the rate of recurrent stenoses after angioplasty but no firm data are available on its possible association with in‐hospital ischemic complications. Methods: We analyzed the data of the registry of the German community hospitals covering approximately one quarter of all interventions in Germany. We included all angioplasty procedures performed in patients with stable coronary artery disease in 1996. Interventions with elective coronary stenting were compared to those with conventional balloon angioplasty. Interventions with bailout stenting were excluded. Results: Of 19,170 angioplasty procedures, 32.2% included elective coronary stenting. The immediate angiographic success rate (residual stenosis &lt; 50%) was 90.6% of the procedures with stents versus 86.3% of those without stents (P &lt; 0.001). The overall incidence of complications (death, myocardial infarction, bypass surgery, vessel closure, reintervention) was 3.9% and 3.8% (NS). Major events (death, myocardial infarction, bypass surgery) were more common in the stent‐treated group (1.8% vs 1.4%, P = 0.027). In multivariate analysis, the following factors were significantly associated with complications: residual stenosis ≥ 50%, female gender, angioplasty of proximal left anterior descending coronary artery, morphological fype of lesion B2 or C, and multivessel disease. Angioplasty of restenoses after previous angioplasty was associated with significantly less risk than of de novo lesions. Stents were neutral with respect to the overall incidence of complications. Conclusions: Complications after elective coronary angioplasty remain largely unpredictable in individual patients despite the identification of several clinical and procedural risk factors. Elective coronary stenting is not associated with the immediate therapeutic risk of angioplasty in stable coronary artery disease.

PTCA registry of German community hospitals. Arbeitsgemeinschaft Leitender Kardiologischer Krankenhausärzte (ALKK) Study Group.

Percutaneous transluminal coronary angioplasty (PTCA) is widely used, but no quality control has been systematically performed as yet. A registry of all PTCA procedures has been established since October 1992 for the majority of the German community hospitals performing PTCA, representing about one third of all PTCA activity in Germany. Baseline demographic data, indication for PTCA, primary success and in-hospital clinical events were recorded. Each centre was visited at regular intervals to assure completeness and reliability of the data. Of 52453 procedures performed from October 1992 to December 1994 the catheter laboratory and discharge forms were 99.7% and 98.1% complete, respectively. In 85.9% a single lesion was dilated per procedure, but 48.7% of the patients had multivessel disease. The success rate was 66.5% in complete occlusions (residual stenosis < 70%) and 91.2% in non-occluded vessels (residual stenosis < 50%). Abrupt vessel closure occurred in 3.4%, of which 77.5% could be recanalized by repeat intervention. In procedures not done for acute myocardial infarction, the in-hospital mortality was 0.52%, the procedure-related mortality 0.37%. In 3.02% of all patients a severe complication occurred (procedure-related death, myocardial infarction or emergency bypass surgery). Complete recording of all PTCA procedures is feasible even on a nationwide basis. This is a pre-requisite for continuous quality control. The reporting of the procedures by itself very probably, has an impact on the quality which is, however, not measurable quantitatively.
