Rates of bacterial co-infections and antimicrobial use in COVID-19 patients: a retrospective cohort study in light of antibiotic stewardship.

The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread worldwide. Bacterial co-infections are associated with unfavourable outcomes in respiratory viral infections; however, microbiological and antibiotic data related to COVID-19 are sparse. Adequate use of antibiotics in line with antibiotic stewardship (ABS) principles is warranted during the pandemic. We performed a retrospective study of clinical and microbiological characteristics of 140 COVID-19 patients admitted between February and April 2020 to a German University hospital, with a focus on bacterial co-infections and antimicrobial therapy. The final date of follow-up was 6 May 2020. Clinical data of 140 COVID-19 patients were recorded: The median age was 63.5 (range 17-99) years; 64% were males. According to the implemented local ABS guidelines, the most commonly used antibiotic regimen was ampicillin/sulbactam (41.5%) with a median duration of 6 (range 1-13) days. Urinary antigen tests for Legionella pneumophila and Streptococcus peumoniae were negative in all cases. In critically ill patients admitted to intensive care units (n = 50), co-infections with Enterobacterales (34.0%) and Aspergillus fumigatus (18.0%) were detected. Blood cultures collected at admission showed a diagnostic yield of 4.2%. Bacterial and fungal co-infections are rare in COVID-19 patients and are mainly prevalent in critically ill patients. Further studies are needed to assess the impact of antimicrobial therapy on therapeutic outcome in COVID-19 patients to prevent antimicrobial overuse. ABS guidelines could help in optimising the management of COVID-19. Investigation of microbial patterns of infectious complications in critically ill COVID-19 patients is also required.

Polyscore of autonomic parameters for risk stratification of the elderly general population: the Polyscore study.

AIMS: Present society is constantly ageing and elderly frequently suffer from conditions that are difficult and/or costly to treat if detected late. Effective screening of the elderly is therefore needed so that those requiring detailed clinical work-up are identified early. We present a prospective validation of a screening strategy based on a Polyscore of seven predominantly autonomic, non-invasive risk markers. METHODS AND RESULTS: Within a population-based survey in Germany (INVADE study), participants aged ≥60 years were enrolled between August 2013 and February 2015. Seven prospectively defined Polyscore components were obtained during 30-min continuous recordings of electrocardiogram, blood pressure, and respiration. Out of 1956 subjects, 168 were excluded due to atrial fibrillation, implanted pacemaker, or unsuitable recordings. All-cause mortality over a median 4-year follow-up was prospectively defined as the primary endpoint. The Polyscore divided the investigated population (n = 1788, median age: 72 years, females: 58%) into three predefined groups with low (n = 1405, 78.6%), intermediate (n = 326, 18.2%), and high risk (n = 57, 3.2%). During the follow-up, 82 (4.6%) participants died. Mortality in the Polyscore-defined risk groups was 3.4%, 7.4%, and 17.5%, respectively (P < 0.0001). The Polyscore-based mortality prediction was independent of Framingham score, diabetes, chronic kidney disease, and major stroke and/or myocardial infarction history. It was particularly effective in those aged <75 years (n = 1145). CONCLUSION: The Polyscore-based mortality risk assessment from short-term non-invasive recordings is effective in the elderly general population, especially those aged 60-74 years. Implementation of a comprehensive Polyscore screening of this age group is proposed to advance preventive medical care.

[Prognostic implications of stone heart syndrome in cardiac arrest]. / Stellenwert des "Stone-heart"-Phänomens bei Herz-Kreislauf-Stillstand.

The stone heart syndrome is defined as an ischemic systolic contracture of the heart and also termed contractile cardiac arrest. It was first described in 1972 by the American cardiac surgeon Denton Cooley, who observed this phenomenon during bypass surgery. It is mostly the result of prolonged cardiac arrest where myocardial cells suffer hypoxia or anoxia. Insufficient forward blood flow and a decreased pressure gradient in the central aorta lead to reduced coronary perfusion. The resulting anaerobic metabolism causes an ischemic contracture as described in the stone heart syndrome. This article presents three cases of patients with traumatic cardiac arrest (TCA) and myocardial contracture in postmortem computed tomography (PMCT) and discuss the origins of the stone heart syndrome as well as its implications in cardiopulmonary resuscitation.

Prediction of mortality benefit based on periodic repolarisation dynamics in patients undergoing prophylactic implantation of a defibrillator: a prospective, controlled, multicentre cohort study.

BACKGROUND: A small proportion of patients undergoing primary prophylactic implantation of implantable cardioverter defibrillators (ICDs) experiences malignant arrhythmias. We postulated that periodic repolarisation dynamics, a novel marker of sympathetic-activity-associated repolarisation instability, could be used to identify electrically vulnerable patients who would benefit from prophylactic implantation of ICDs by way of a reduction in mortality. METHODS: We did a prespecified substudy of EUropean Comparative Effectiveness Research to Assess the Use of Primary ProphylacTic Implantable Cardioverter Defibrillators (EU-CERT-ICD), a prospective, investigator-initiated, non-randomised, controlled cohort study done at 44 centres in 15 EU countries. Patients aged 18 years or older with ischaemic or non-ischaemic cardiomyopathy and reduced left ventricular ejection fraction (≤35%) were eligible for inclusion if they met guideline-based criteria for primary prophylactic implantation of ICDs. Periodic repolarisation dynamics from 24-h Holter recordings were assessed blindly in patients the day before ICD implantation or on the day of study enrolment in patients who were conservatively managed. The primary endpoint was all-cause mortality. Propensity scoring and multivariable models were used to assess the interaction between periodic repolarisation dynamics and the treatment effect of ICDs on mortality. FINDINGS: Between May 12, 2014, and Sept 7, 2018, 1371 patients were enrolled in our study. 968 of these patients underwent ICD implantation, and 403 were treated conservatively. During follow-up (median 2·7 years [IQR 2·0-3·3] in the ICD group and 1·2 years [0·8-2·7] in the control group), 138 (14%) patients died in the ICD group and 64 (16%) patients died in the control group. We noted a 43% reduction in mortality in the ICD group compared with the control group (adjusted hazard ratio [HR] 0·57 [95% CI 0·41-0·79]; p=0·0008). Periodic repolarisation dynamics significantly predicted the treatment effect of ICDs on mortality (adjusted p=0·0307). The mortality benefits associated with ICD implantation were greater in patients with periodic repolarisation dynamics of 7·5 deg or higher (n=199; adjusted HR 0·25 [95% CI 0·13-0·47] for the ICD group vs the control group; p<0·0001) than in those with periodic repolarisation dynamics less than 7·5 deg (n=1166; adjusted HR 0·69 [95% CI 0·47-1·00]; p=0·0492; pinteraction=0·0056). The number needed to treat was 18·3 (95% CI 10·6-4895·3) in patients with periodic repolarisation dynamics less than 7·5 deg and 3·1 (2·6-4·8) in those with periodic repolarisation dynamics of 7·5 deg or higher. INTERPRETATION: Periodic repolarisation dynamics predict mortality reductions associated with prophylactic implantation of ICDs in contemporarily treated patients with ischaemic or non-ischaemic cardiomyopathy. Periodic repolarisation dynamics could help to guide treatment decisions about prophylactic ICD implantation. FUNDING: The European Community's 7th Framework Programme.

Code Stroke Patient Referral by Emergency Medical Services During the Public COVID-19 Pandemic Lockdown.

BACKGROUND: The COVID-19 pandemic caused public lockdowns around the world. We analyzed if the public lockdown altered the referral pattern of Code Stroke patients by Emergency Medical Services (EMS) to our Comprehensive Stroke Center. METHODS: Retrospective single-center study at a Bavarian Comprehensive Stroke Center. Patients who were directly referred to our stroke unit by EMS between the 1st of January 2020 and the 19th of April 2020 were identified and number of referrals, clinical characteristics and treatment strategies were analyzed during the public lockdown and before. The public lockdown started on 21st of March and ended on 19th April 2020. RESULTS: In total 241 patients were referred to our center during the study period, i.e. 171 before and 70 during the lockdown. The absolute daily number of Code Stroke referrals and the portion of patients with stroke mimics remained stable. The portion of female stroke patients decreased (55% to 33%; p = 0.03), and stroke severity as measured by the National Institutes of Health Stroke Scale (median 3 (IQR 0-7) versus 6 (IQR 1-15.5) points; p = 0.04) increased during the lockdown. There was no difference of daily numbers of patients receiving thrombolysis and thrombectomy. CONCLUSIONS: Referral of Code Stroke patients by EMS could be maintained sufficiently despite the COVID-19 pandemic lockdown. However, patients' health care utilization of the EMS may have changed within the public lockdown. EMS remains a useful tool for Code Stroke patient referral during lockdowns, but public education about stroke is required prior to further lockdowns.

[Strategy for university emergency room management at the beginning of an epidemic using COVID-19 as an example]. / Strategie einer universitären Notaufnahme für das COVID-19-Management im Rahmen einer beginnenden Epidemie.

Due to the increasing number of COVID-19 infections worldwide, all hospitals are faced with the challenge associated with the pandemic. In particular, emergency rooms must prepare and implement completely new workflows. This applies in particular to patient screening and selection (triage). Close cooperation with other specialist areas such as hygiene, infectiology or virology is also necessary in order to implement appropriate treatment concepts before, during and after the diagnosis is completed. In addition, communication and quality and risk management are highly relevant in addition to the clinical aspects. This article uses COVID-19 as an example to describe how emergency rooms can prepare for a pandemic.

Present criteria for prophylactic ICD implantation: Insights from the EU-CERT-ICD (Comparative Effectiveness Research to Assess the Use of Primary ProphylacTic Implantable Cardioverter Defibrillators in EUrope) project.

BACKGROUND: The clinical effectiveness of primary prevention implantable cardioverter defibrillator (ICD) therapy is under debate. It is urgently needed to better identify patients who benefit from prophylactic ICD therapy. The EUropean Comparative Effectiveness Research to Assess the Use of Primary ProphylacTic Implantable Cardioverter Defibrillators (EU-CERT-ICD) completed in 2019 will assess this issue. SUMMARY: The EU-CERT-ICD is a prospective investigator-initiated non-randomized, controlled, multicenter observational cohort study done in 44 centers across 15 European countries. A total of 2327 patients with heart failure due to ischemic heart disease or dilated cardiomyopathy indicated for primary prophylactic ICD implantation were recruited between 2014 and 2018 (>1500 patients at first ICD implantation, >750 patients non-randomized non-ICD control group). The primary endpoint was all-cause mortality, and first appropriate shock was co-primary endpoint. At baseline, all patients underwent 12­lead ECG and Holter-ECG analysis using multiple advanced methods for risk stratification as well as documentation of clinical characteristics and laboratory values. The EU-CERT-ICD data will provide much needed information on the survival benefit of preventive ICD therapy and expand on previous prospective risk stratification studies which showed very good applicability of clinical parameters and advanced risk stratifiers in order to define patient subgroups with above or below average ICD benefit. CONCLUSION: The EU-CERT-ICD study will provide new and current data about effectiveness of primary prophylactic ICD implantation. The study also aims for improved risk stratification and patient selection using clinical risk markers in general, and advanced ECG risk markers in particular.

Sex differences in outcomes of primary prevention implantable cardioverter-defibrillator therapy: combined registry data from eleven European countries.

Aims: Therapy with an implantable cardioverter defibrillator (ICD) is established for the prevention of sudden cardiac death (SCD) in high risk patients. We aimed to determine the effectiveness of primary prevention ICD therapy by analysing registry data from 14 centres in 11 European countries compiled between 2002 and 2014, with emphasis on outcomes in women who have been underrepresented in all trials. Methods and results: Retrospective data of 14 local registries of primary prevention ICD implantations between 2002 and 2014 were compiled in a central database. Predefined primary outcome measures were overall mortality and first appropriate and first inappropriate shocks. A multivariable model enforcing a common hazard ratio for sex category across the centres, but allowing for centre-specific baseline hazards and centre specific effects of other covariates, was adjusted for age, the presence of ischaemic cardiomyopathy or a CRT-D, and left ventricular ejection fraction ≤25%. Of the 5033 patients, 957 (19%) were women. During a median follow-up of 33 months (IQR 16-55 months) 129 women (13%) and 807 men (20%) died (HR 0.65; 95% CI: [0.53, 0.79], P-value < 0.0001). An appropriate ICD shock occurred in 66 women (8%) and 514 men (14%; HR 0.61; 95% CI: 0.47-0.79; P = 0.0002). Conclusion: Our retrospective analysis of 14 local registries in 11 European countries demonstrates that fewer women than men undergo ICD implantation for primary prevention. After multivariate adjustment, women have a significantly lower mortality and receive fewer appropriate ICD shocks.

High on-treatment platelet reactivity and outcomes after percutaneous endovascular procedures in patients with peripheral artery disease.

BACKGROUND: High on-treatment platelet reactivity (HPR) predicts adverse cardiovascular events in patients with coronary artery disease. The impact of HPR in patients with peripheral artery disease (PAD) after peripheral endovascular procedures is unclear. PATIENTS AND METHODS: A total of 385 patients with PAD and successful percutaneous endovascular procedure were included. Patients received aspirin as a long-term treatment in addition to the P2Y12 receptor antagonist clopidogrel, as recommended after such a procedure for at least 1 month. Platelet function was assessed on a Multiplate analyzer. The primary endpoint was target lesion revascularization (TLR) at one year. Restenosis (≥ 75 %) in duplex sonography, mortality at one year and identification of independent predictors of TLR were secondary endpoints. RESULTS: TLR rates were similar in HPR and no-HPR patients (14.3 % vs. 12.7 %, hazard rate (HR) 0.94, 95 % CI 0.48 - 1.84, P = 0.86). Restenosis (≥ 75 %) in duplex sonography did not differ between the two study groups (15.6 % vs. 16.9 %, HR 1.16, 95% CI 0.62 - 2.12, P = 0.64). Independent predictors of TLR were intervention of restenotic lesions, total vessel occlusions and critical limb ischemia, but not HPR (adjusted HR 1.07, 95% CI 0.55 - 2.10, P = 0.84). No difference in mortality at one year was observed (1.3 % vs. 1.6 %, HR 1.28, 95 % CI 0.15 - 11.0, P = 0.82). CONCLUSIONS: In patients with PAD, HPR did not have a significant impact on outcomes within the first year after percutaneous endovascular intervention.

Impact of sympathetic renal denervation: a randomized study in patients after renal transplantation (ISAR-denerve).

BACKGROUND: Sympathetic overactivity is frequently observed following renal transplantation (RTx), and post-transplant hypertension is a major contributing factor to graft failure and cardiovascular morbidity. This process is perpetuated by preservation of sympathetic afferent activity from the native non-functional kidneys, in the absence of efferent feedback to the renal transplant, which would otherwise modulate neurohumoral activity. We investigated the feasibility and efficacy of renal sympathetic denervation (RDN) in renal transplant recipients. METHODS: Patients (n = 18) with post-transplant hypertension were randomized 1:1 to receive RDN or medical treatment alone. The primary efficacy end point was change in office systolic blood pressure (SBP) and mean 24-h ambulatory blood pressure monitoring (ABPM) at 6 months. Safety end points were changes in renal function or renovascular complications. RESULTS: After 6 months, patients in the RDN group had a significant reduction in office SBP of 23.3 ± 14.5 mmHg (P = 0.001 for change difference between the groups). In ABPM, nocturnal blood pressure was reduced in the RDN group by -10.38 ± 12.8 mmHg (P = 0.06), whereas no change was measured during the day. In the RDN group, significantly more patients converted from non-dippers to dippers (P = 0.035). There were no adverse safety events in either group. CONCLUSION: RDN is feasible and safe in renal transplant recipients. However, larger sham-controlled studies will be necessary to clarify the potential role of RDN in this population. CLINICAL TRIAL REGISTRATION: NCT01899456.

Endovascular therapy for steno-occlusive subclavian and innominate artery disease.

BACKGROUND: This study investigated the safety and outcome of endovascular therapy for steno-occlusive subclavian or innominate artery disease at a single center over a long period of more than 2 decades. METHODS AND RESULTS: We retrospectively analyzed all endovascular procedures of stenosis or occlusion of the subclavian or innominate artery between January 1990 and October 2013. During the observation period, a total of 130 procedures were attempted in 127 mostly symptomatic patients with stenosis (n=108; 83%) or occlusion (n=22; 17%) of the subclavian (n=119; 92%) and innominate (n=11; 8%) artery. The overall technical success rate was 97.7% (n=127/130). Accounting for the type of lesion, the success rate for stenosis was 100% (n=108/108) and for total occlusion, 86% (n=19/22). The periprocedural complication rate was low and included stroke, transient ischemic attack, and access site complications of 0.8%, 1.5%, and 3.8%, respectively. During a mean follow-up of 28 months the rate of restenosis (>70%) was 12%. Due to the overall low event rate no significant lesion or procedural risk factor for the development of restenosis could be identified. CONCLUSIONS: Stenosis and occlusion of the subclavian and innominate artery can be treated safely and successfully by endovascular therapy with excellent long-term patency.

Assessment of mean respiratory rate from ECG recordings for risk stratification after myocardial infarction.

BACKGROUND: We recently reported that nocturnal respiratory rate (NRR) predicts non-sudden cardiac death in survivors of myocardial infarction (MI). Here, we present the details of the technique deriving NRR from ECG recordings. METHODS: Continuous ECG and respiratory chest excursions were simultaneously recorded in 941 MI survivors who were followed-up for 5-years. Mean respiratory rate was derived from the ECG based on RR intervals, QRS amplitudes, and QRS vectors and compared to chest belt measurements. NRR was calculated from Holter-ECGs accordingly using the same ECG processing. RESULTS: Directly-measured and ECG-derived respiratory rates were in good agreement. Areas under the ROC curve for 10-min-ECG- and Holter-derived respiratory rate were well in the confidence intervals of that of the chest belt measurement. The optimum dichotomy of NRR for the prediction of mortality was ≥18.6 breaths per minute. CONCLUSIONS: The mean respiratory rate can be precisely derived from continuous ECGs.

Sex differences in the non-invasive risk stratification and prognosis after myocardial infarction.

BACKGROUND: Women have unfavorable prognosis after myocardial infarction (MI). This text describes sex differences in mortality and in the power of risk predictors in contemporarily-treated MI patients. METHODS: A population of 4141 MI patients (26.5% females) was followed up for 5years. Effects of sex and age on total mortality were investigated by multivariable Cox analysis. Mortality predictors were investigated by receiver-operator characteristics analysis. Stepwise multivariable Cox regression was used to create sex-specific predictive models. RESULTS: Thirty-day mortality was 1.5-fold higher in women. However, sex was not a significant mortality predictor in a model adjusted for age. Predictors for 5-year mortality performed differently in male and female patients. In women, a sex-specific model provided better risk stratification than a sex-neutral model. CONCLUSION: The unfavorable prognosis of female MI patients can be explained by advanced age. Sex-specific predictive models might improve risk stratification in female survivors of acute MI.

[Impact of the COVID-19 pandemic on the care of major trauma patients: analysis from the TraumaRegister DGU®]. / Auswirkung der COVID-19-Pandemie auf die Versorgung von Schwerverletzten: Analyse aus dem TraumaRegister DGU®.

BACKGROUND: The treatment of major trauma patients requires intensive care capacity, which is a critical resource particularly during the coronavirus disease 2019 (COVID-19) pandemic. Therefore, the aim of this study was to analyze the impact on major trauma care considering the intensive care treatment of COVID-19 positive patients. METHODS: Demographic, prehospital, and intensive care treatment data from the TraumaRegister DGU® of the German Trauma Society (DGU) in 2019 and 2020 were analyzed. Only major trauma patients from the state of Bavaria were included. Inpatient treatment data of COVID-19 patients in Bavaria in 2020 were obtained using IVENA eHealth. RESULTS: In total, 8307 major trauma patients were treated in the state of Bavaria in the time period investigated. The number of patients in 2020 (n = 4032) compared to 2019 (n = 4275) was not significantly decreased (p = 0.4). Regarding COVID-19 case numbers, maximum values were reached in the months of April and December with more than 800 intensive care unit (ICU) patients per day. In the critical period (> 100 patients with COVID-19 on ICU), a prolonged rescue time was evident (64.8 ± 32.5 vs. 67.4 ± 30.6 min; p = 0.003). The length of stay and ICU treatment of major trauma patients were not negatively affected by the COVID-19 pandemic. CONCLUSION: The intensive medical care of major trauma patients could be ensured during the high-incidence phases of the COVID-19 pandemic. The prolonged prehospital rescue times show possible optimization potential of the horizontal integration of prehospital and hospital.

Circulating Hsp70 Levels and the Immunophenotype of Peripheral Blood Lymphocytes as Potential Biomarkers for Advanced Lung Cancer and Therapy Failure after Surgery.

Lung cancer remains a devastating disease with a poor clinical outcome. A biomarker signature which could distinguish lung cancer from metastatic disease and detect therapeutic failure would significantly improve patient management and allow for individualized, risk-adjusted therapeutic decisions. In this study, circulating Hsp70 levels were measured using ELISA, and the immunophenotype of the peripheral blood lymphocytes were measured using multiparameter flow cytometry, to identify a predictive biomarker signature for lung cancer patients pre- and post-operatively, in patients with lung metastases and in patients with COPD as an inflammatory lung disease. The lowest Hsp70 concentrations were found in the healthy controls followed by the patients with advanced COPD. Hsp70 levels sequentially increased with an advancing tumor stage and metastatic disease. In the early-recurrence patients, Hsp70 levels started to increase within the first three months after surgery, but remained unaltered in the recurrence-free patients. An early recurrence was associated with a significant drop in B cells and an increase in Tregs, whereas the recurrence-free patients had elevated T and NK cell levels. We conclude that circulating Hsp70 concentrations might have the potential to distinguish lung cancer from metastatic disease, and might be able to predict an advanced tumor stage and early recurrence in lung cancer patients. Further studies with larger patient cohorts and longer follow-up periods are needed to validate Hsp70 and immunophenotypic profiles as predictive biomarker signatures.

The Polyscore of autonomic parameters predicts mortality and identifies low-risk individuals among diabetic survivors of acute myocardial infarction.

Survivors of an acute myocardial infarction with diabetes mellitus retain an increased mortality risk. Reliable assessment of individual risk is required for effective and cost-efficient medical care in these patients. The Polyscore is a previously established risk predictor consisting of seven autonomic tests derived from electrocardiogram, blood pressure, and respiration. The Polyscore allows classification of survivors of myocardial infarction in groups at low, intermediate and high mortality risk. The aim of this study was to investigate the prognostic value of the Polyscore in diabetic survivors of acute myocardial infarction, which may be impaired by the presence of diabetic autonomic neuropathy. Survivors of an acute myocardial infarction were included in a prospective cohort study during hospitalisation due to the index event at two university hospitals in Munich, Germany. The Polyscore was determined from simultaneous non-invasive 30-min recordings of electrocardiogram, continuous arterial blood pressure, and respiration which were performed in all participants. Patients were followed for 5 years. The primary and secondary outcomes were all-cause mortality and cardiac mortality. 184 of 941 enrolled patients (19.6%) suffered from diabetes mellitus. 5-year-mortality was higher in diabetic patients (15.2%) compared to non-diabetic patients (5.8%). A multivariable Cox regression model confirmed the Polyscore as a strong predictor of mortality in diabetic post-MI patients (intermediate risk: HR 6.56, 95% CI 1.61-26.78, p = 0.004, mortality 22.8%; high risk: HR 18.76, 95% CI 4.35-80.98, p < 0.001, mortality 68.8%). There was no interaction between diabetes mellitus and the Polyscore regarding mortality prediction (p = 0.775). Interestingly, in contrast to the groups at intermediate and high risk (73 patients, 39.7%), the Polyscore identified a majority of diabetic patients (111, 60.3%) with a low mortality risk, comparable to that of low-risk non-diabetic patients (3.6% and 2.1%, respectively, p = 0.339). Consistent results were observed for cardiac mortality. This analysis shows that the Polyscore predicts all-cause and cardiac mortality in diabetic survivors of acute myocardial infarction. Within these patients it identifies a large population not affected by the excess mortality associated with diabetes in this setting. Thus, the Polyscore may facilitate risk-adapted follow-up strategies in diabetic survivors of myocardial infarction.

Integration of mobile sensors in a telemedicine hospital system: remote-monitoring in COVID-19 patients.

Aim: The goal is to design and, in a next step, establish a scalable, multi-center telemonitoring platform based on existing systems for monitoring COVID-19 patients in home quarantine. In particular, the focus will be on raw data acquisition, integration of sensor data into the hospital system, structured data storage, and interoperability. Subject and methods: Data necessary for monitoring, otherwise provided in various portals, will be continuously queried and integrated into the hospital system via a new interface in this proof-of-concept work. Results: Based on extensive preliminary work at Klinikum rechts der Isar with a structured clinical database, we extend our system's integration of raw data and visualization in dashboards, as well as scientific provision of data from mobile sensors for monitoring patients in home quarantine. Conclusion: Based on existing integrated telemonitoring systems supporting semantic and syntactic interoperability, short-term provision of scientific databases is possible. The integration of different mobile sensors into a clinical system for remote monitoring of patients around the clock is still new and to our knowledge unique.
