Abstract
OBJECTIVE The optimal target for blood glucose concentration in critically ill patients is unclear. We will perform a systematic review and meta-analysis with aggregated and individual patient data from randomized controlled trials, comparing intensive glucose control with liberal glucose control in critically ill adults. DATA SOURCES MEDLINE®, Embase, the Cochrane Central Register of Clinical Trials, and clinical trials registries (World Health Organization, clinical trials.gov). The authors of eligible trials will be invited to provide individual patient data. Published trial-level data from eligible trials that are not at high risk of bias will be included in an aggregated data meta-analysis if individual patient data are not available. METHODS Inclusion criteria: randomized controlled trials that recruited adult patients, targeting a blood glucose of ≤ 120mg/dL (≤ 6.6mmol/L) compared to a higher blood glucose concentration target using intravenous insulin in both groups. Excluded studies: those with an upper limit blood glucose target in the intervention group of > 120mg/dL (> 6.6mmol/L), or where intensive glucose control was only performed in the intraoperative period, and those where loss to follow-up exceeded 10% by hospital discharge. PRIMARY ENDPOINT In-hospital mortality during index hospital admission. Secondary endpoints: mortality and survival at other timepoints, duration of invasive mechanical ventilation, vasoactive agents, and renal replacement therapy. A random effect Bayesian meta-analysis and hierarchical Bayesian models for individual patient data will be used. DISCUSSION This systematic review with aggregate and individual patient data will address the clinical question, 'what is the best blood glucose target for critically ill patients overall?'Protocol version 0.4 - 06/26/2023PROSPERO registration:CRD42021278869.

Hemoadsorption in the critically ill-Final results of the International CytoSorb Registry. PLoS One 2022; 17:e0274315. [PMID: 36282800 PMCID: PMC9595535 DOI: 10.1371/journal.pone.0274315] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Accepted: 08/25/2022] [Indexed: 12/23/2022] Open
Abstract
The aim of the current paper is to summarize the results of the International CytoSorb Registry. Data were collected on patients of the intensive care unit. The primary endpoint was actual in-hospital mortality compared to the mortality predicted by APACHE II score. The main secondary endpoints were SOFA scores, inflammatory biomarkers and overall evaluation of the general condition. 1434 patients were enrolled. Indications for hemoadsorption were sepsis/septic shock (N = 936); cardiac surgery perioperatively (N = 172); cardiac surgery postoperatively (N = 67) and "other" reasons (N = 259). APACHE-II-predicted mortality was 62.0±24.8%, whereas observed hospital mortality was 50.1%. Overall SOFA scores did not change but cardiovascular and pulmonary SOFA scores decreased by 0.4 [-0.5;-0.3] and -0.2 [-0.3;-0.2] points, respectively. Serum procalcitonin and C-reactive protein levels showed significant reduction: -15.4 [-19.6;-11.17] ng/mL; -17,52 [-70;44] mg/L, respectively. In the septic cohort PCT and IL-6 also showed significant reduction: -18.2 [-23.6;-12.8] ng/mL; -2.6 [-3.0;-2.2] pg/mL, respectively. Evaluation of the overall effect: minimal improvement (22%), much improvement (22%) and very much improvement (10%), no change observed (30%) and deterioration (4%). There was no significant difference in the primary outcome of mortality, but there were improvements in cardiovascular and pulmonary SOFA scores and a reduction in PCT, CRP and IL-6 levels. Trial registration: ClinicalTrials.gov Identifier: NCT02312024 (retrospectively registered).

Estimating extra length of stay due to healthcare-associated infections before and after implementation of a hospital-wide infection control program. PLoS One 2019; 14:e0217159. [PMID: 31100094 PMCID: PMC6524816 DOI: 10.1371/journal.pone.0217159] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2019] [Accepted: 05/04/2019] [Indexed: 11/24/2022] Open
Abstract
Introduction Healthcare-associated infections (HAIs) are a major health concern and have substantial effects on morbidity and mortality and increase healthcare costs. We investigated the effect of a hospital-wide program for the prevention of HAIs on additional length of stay (LOS). Methods We analyzed data from a prospective, single-center, quasi-experimental study with two surveillance periods before and after implementation of an infection prevention intervention program. HAI diagnosis was made according to surveillance definition criteria established by the US Centers for Disease Control and Prevention. A multistate model was used to estimate additional LOS for patients with HAI in both surveillance periods. Results During the first and second periods, 1,568 and 2,336 HAIs were identified among 26,943 and 35,211 patients, respectively. For HAI patients exclusively treated in a general ward, additional LOS was 8.4 (95% confidence interval, CI: 6.8–10.0) days in the first period and 9.6 (95% CI: 8.3–11.0) days in the second period (p = 0.26). For HAI patients treated in both an intensive care unit (ICU) and a general ward, additional LOS was 8.1 (95% CI: 6.3–9.9) days in the first period to 7.3 (95% CI: 6.1–8.5) days in the second period (p = 0.47). Conclusions Healthcare-associated infections prolong LOS. A hospital-wide infection control program did not alter the prolongation of LOS.

Sequential organ failure assessment score is an excellent operationalization of disease severity of adult patients with hospitalized community acquired pneumonia - results from the prospective observational PROGRESS study. Crit Care 2019; 23:110.

Abstract
BACKGROUND CAP (Community acquired pneumonia) is frequent, with a high mortality rate and a high burden on health care systems. Development of predictive biomarkers, new therapeutic concepts, and epidemiologic research require a valid, reproducible, and quantitative measure describing CAP severity. METHODS Using time series data of 1532 patients enrolled in the PROGRESS study, we compared putative measures of CAP severity for their utility as an operationalization. Comparison was based on ability to correctly identify patients with an objectively severe state of disease (death or need for intensive care with at least one of the following: substantial respiratory support, treatment with catecholamines, or dialysis). We considered IDSA/ATS minor criteria, CRB-65, CURB-65, Halm criteria, qSOFA, PSI, SCAP, SIRS-Score, SMART-COP, and SOFA. RESULTS SOFA significantly outperformed other scores in correctly identifying a severe state of disease at the day of enrollment (AUC = 0.948), mainly caused by higher discriminative power at higher score values. Runners-up were the sum of IDSA/ATS minor criteria (AUC = 0.916) and SCAP (AUC = 0.868). SOFA performed similarly well on subsequent study days (all AUC > 0.9) and across age groups. In univariate and multivariate analysis, age, sex, and pack-years significantly contributed to higher SOFA values whereas antibiosis before hospitalization predicted lower SOFA. CONCLUSIONS SOFA score can serve as an excellent operationalization of CAP severity and is proposed as endpoint for biomarker and therapeutic studies.

Abstract
The adoption of the new sepsis definition in early 2016 introduced a new paradigm for the clinical picture of sepsis. Up until now, sepsis was defined as a systemic inflammatory reaction (systemic inflammatory response syndrome, SIRS) to an infection. Based on a better understanding of the molecular mechanisms, the focus of the new definition is no longer the inflammatory response, but rather the tissue damage and impairment of organ function which this induces. The paradigm thus moves away from the infection and the systemic inflammatory response, and toward that which makes sepsis so dangerous in terms of both disease dynamics and outcome: organ failure due to a dysregulated host response to an infection. This change of perspective or paradigm enables patients with an increased risk of developing sepsis to be recognized and treated earlier in clinical routine, even outside of the intensive care unit. The new definition also promotes development of new treatment strategies with improved ability to treat sepsis causally.

Effectiveness of a hospital-wide infection control programme on the incidence of healthcare-associated infections and associated severe sepsis and septic shock: a prospective interventional study. Clin Microbiol Infect 2018; 25:462-468. [PMID: 30036671 DOI: 10.1016/j.cmi.2018.07.010] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Revised: 07/03/2018] [Accepted: 07/07/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVES To evaluate whether a hospital-wide infection control programme (ICP) is effective at reducing the burden of healthcare-associated infections (HAIs) and associated severe sepsis/septic shock or death (severe HAIs). METHODS Prospective, quasi-experimental study with two surveillance periods (September 2011 to August 2012; May 2013 to August 2014). Starting October 2012, the ICP included hand hygiene promotion and bundle implementation for common HAIs. We applied segmented mixed-effects Poisson regression and multi-state models. We reported adjusted incidence rate ratios (aIRR) and adjusted hazard ratios (aHR) with 95% confidence intervals (CI). RESULTS Overall, 62 154 patients were under surveillance, with 1568 HAIs identified in 1170 patients (4.3 per 100 admissions) in the first and 2336 HAIs identified in 1711 patients (4.9 per 100 admissions) in the second surveillance period. No differences were found in the overall HAI incidence rates between the periods in the general wards (aIRR 1.29, 95% CI 0.78-2.15) and intensive care units (ICUs) (aIRR 0.59, 95% CI 0.27-1.31). However, the HAI incidence rate was declining in the ICUs after starting the ICP (aIRR 0.98, 95% CI 0.97-1.00 per 1-week increment), in contrast to general wards (aIRR 1.01, 95% CI 1.00-1.02). A reduction in severe HAIs (aIRR 0.13, 95% CI 0.05-0.32) and a lower probability of HAI-associated in-hospital deaths (aHR 0.56, 95% CI 0.31-0.99) were observed in the second period in the ICUs. CONCLUSIONS There was no overall reduction in HAIs after implementation of the ICP. However, there was a significant reduction in severe HAIs in ICUs. Whether this difference was a consequence of the ICP or improvement in HAI case management is not clear.

The use of mid-regional proadrenomedullin to identify disease severity and treatment response to sepsis - a secondary analysis of a large randomised controlled trial. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2018; 22:79. [PMID: 29562917 PMCID: PMC5863464 DOI: 10.1186/s13054-018-2001-5] [Citation(s) in RCA: 67] [Impact Index Per Article: 11.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/15/2017] [Accepted: 02/19/2018] [Indexed: 02/08/2023]
Abstract
Background This study assessed the ability of mid-regional proadrenomedullin (MR-proADM) in comparison to conventional biomarkers (procalcitonin (PCT), lactate, C-reactive protein) and clinical scores to identify disease severity in patients with sepsis. Methods This is a secondary analysis of a randomised controlled trial in patients with severe sepsis or septic shock across 33 German intensive care units. The association between biomarkers and clinical scores with mortality was assessed by Cox regression analysis, area under the receiver operating characteristic and Kaplan-Meier curves. Patients were stratified into three severity groups (low, intermediate, high) for all biomarkers and scores based on cutoffs with either a 90% sensitivity or specificity. Results 1089 patients with a 28-day mortality rate of 26.9% were analysed. According to the Sepsis-3 definition, 41.2% and 58.8% fulfilled the criteria for sepsis and septic shock, with respective mortality rates of 20.0% and 32.1%. MR-proADM had the strongest association with mortality across all Sepsis-1 and Sepsis-3 subgroups and could facilitate a more accurate classification of low (e.g. MR-proADM vs. SOFA: N = 265 vs. 232; 9.8% vs. 13.8% mortality) and high (e.g. MR-proADM vs. SOFA: N = 161 vs. 155; 55.9% vs. 41.3% mortality) disease severity. Patients with decreasing PCT concentrations of either ≥ 20% (baseline to day 1) or ≥ 50% (baseline to day 4) but continuously high MR-proADM concentrations had a significantly increased mortality risk (HR (95% CI): 19.1 (8.0–45.9) and 43.1 (10.1–184.0)). Conclusions MR-proADM identifies disease severity and treatment response more accurately than established biomarkers and scores, adding additional information to facilitate rapid clinical decision-making and improve personalised sepsis treatment.

Abstract
INTRODUCTION The aim of this clinical registry is to record the use of CytoSorb® adsorber device in critically ill patients under real-life conditions. METHODS The registry records all relevant information in the course of product use, e. g., diagnosis, comorbidities, course of the condition, treatment, concomitant medication, clinical laboratory parameters, and outcome (ClinicalTrials.gov Identifier: NCT02312024). Primary endpoint is in-hospital mortality as compared to the mortality predicted by the APACHE II and SAPS II score, respectively. RESULTS As of January 30, 2017, 130 centers from 22 countries were participating. Data available from the start of the registry on May 18, 2015 to November 24, 2016 (122 centers; 22 countries) were analyzed, of whom 20 centers from four countries provided data for a total of 198 patients (mean age 60.3 ± 15.1 years, 135 men [68.2%]). In all, 192 (97.0%) had 1 to 5 Cytosorb® adsorber applications. Sepsis was the most common indication for CytoSorb® treatment (135 patients). Mean APACHE II score in this group was 33.1 ± 8.4 [range 15-52] with a predicted risk of death of 78%, whereas the observed mortality was 65%. There were no significant decreases in the SOFA scores after treatment (17.2 ± 4.8 [3-24]). However interleukin-6 levels were markedly reduced after treatment (median 5000 pg/ml before and 289 pg/ml after treatment, respectively). CONCLUSIONS This third interim report demonstrates the feasibility of the registry with excellent data quality and completeness from 20 study centers. The results must be interpreted with caution, since the numbers are still small; however the disease severity is remarkably high and suggests that adsorber treatment might be used as an ultimate treatment in life-threatening situations. There were no device-associated side effects.

Abstract
INTRODUCTION Staphylococcus aureus bacteraemia (SAB) is a frequent infection with high mortality rates. It requires specific diagnostic and therapeutic management such as prolonged intravenous administration of antibiotics and aggressive search for and control of infectious sources. Underestimation of disease severity frequently results in delayed or inappropriate management of patients with SAB leading to increased mortality rates. According to observational studies, patient counselling by infectious disease consultants (IDC) improves survival and reduces the length of hospital stay as well as complication rates. In many countries, IDC are available only in some tertiary hospitals. In this trial, we aim to demonstrate that the outcome of patients with SAB in small and medium size hospitals that do not employ IDC can be improved by unsolicited ID phone counselling. The SUPPORT trial will be the first cluster-randomised controlled multicentre trial addressing this question. METHODS AND ANALYSIS SUPPORT is a single-blinded, multicentre interventional, cluster-randomised, controlled crossover trial with a minimum of 15 centres that will include 250 patients with SAB who will receive unsolicited IDC counselling and 250 who will receive standard of care. Reporting of SAB will be conducted by an electronic real-time blood culture registry established for the German Federal state of Thuringia (ALERTSNet) or directly by participating centres in order to minimise time delay before counselling. Mortality, disease course and complications will be monitored for 90 days with 30-day all-cause mortality rates as the primary outcome. Generalised linear mixed modelling will be used to detect the difference between the intervention sequences. We expect improved outcome of patients with SAB after IDC. ETHICS AND DISSEMINATION We obtained ethics approval from the Ethics committee of the Jena University Hospital and from the Ethics committee of the State Chamber of Physicians of Thuringia. Results will be published in a peer-reviewed journal and additionally disseminated through public media. TRIAL REGISTRATION NUMBER DRKS00010135.

Abstract
OBJECTIVES This article systematically reviews research on the costs of sepsis and, as a secondary aim, evaluates the quality of economic evaluations reported in peer-reviewed journals. METHODS We systematically searched the MEDLINE, National Health Service (Abstracts of Reviews of Effects, Economic Evaluation and Health Technology Assessment), Cost-effectiveness Analysis Registry and Web of Knowledge databases for studies published between January 2005 and June 2015. We selected original articles that provided cost and cost-effectiveness analyses, defined sepsis and described their cost calculation method. Only studies that considered index admissions and re-admissions in the first 30 days were published in peer-reviewed journals and used standard treatments were considered. All costs were adjusted to 2014 US dollars. Medians and interquartile ranges (IQRs) for various costs of sepsis were calculated. The quality of economic studies was assessed using the Drummond 10-item checklist. RESULTS Overall, 37 studies met our eligibility criteria. The median of the mean hospital-wide cost of sepsis per patient was $32,421 (IQR $20,745-$40,835), and the median of the mean ICU cost of sepsis per patient was $27,461 (IQR $16,007-$31,251). Overall, the quality of economic studies was low. CONCLUSIONS Estimates of the hospital-related costs of sepsis varied considerably across the included studies depending on the method used for cost calculation, the type of sepsis and the population that was examined. A standard model for conducting cost improve the quality of studies on the costs of sepsis.

Abstract
OBJECTIVE To evaluate the effect of pre-operative octenidine (OCT) decolonization on surgical site infection (SSI) rates. DESIGN Before-and-after cohort study. PATIENTS Patients undergoing an elective isolated coronary artery bypass graft (CABG) procedure: control group (1st January to 31st December 2013), N=475; intervention group (1st January to 31st December 2014), N=428. INTERVENTIONS The intervention consisted of nasal application of OCT ointment three times daily, beginning on the day before surgery, and showering the night before and on the day of surgery with OCT soap. RESULTS A median sternotomy was performed in 805 (89.1%) patients and a minimally invasive direct coronary artery bypass procedure was performed in 98 (10.9%) patients. Overall, there was no difference in SSI rates between the control and intervention groups (15.4% vs 13.3%, P=0.39). The rate of harvest site SSIs was significantly lower in patients in the intervention group (2.5% vs 0.5%, P=0.01). Patients who had undergone a median sternotomy in the intervention group had a significantly lower rate of organ/space sternal SSIs (1.9% vs 0.3%, P=0.04). However, there was a trend towards an increased rate of deep incisional sternal SSIs (1.2% vs 2.9%, P=0.08). Multi-variate analysis did not identify a significant protective effect of the intervention (odds ratio 0.79, 95% confidence interval 0.53-1.15, P=0.27). CONCLUSIONS Pre-operative decolonization with OCT did not reduce overall SSI rates in patients undergoing an elective isolated CABG procedure, but significantly decreased harvest site and organ/space sternal SSIs. Randomized controlled trials, including controlled patient adherence to the intervention, are required to confirm these observations and to determine the clinical utility of OCT in pre-operative decolonization.

Abstract
Systemic inflammatory response syndrome (SIRS) is a life threatening condition and the leading cause of death in intensive care units. Although single aspects of pathophysiology have been described in detail, numerous unknown mediators contribute to the progression of this complex disease. The aim of this study was to elucidate the pathophysiological role of CAAP48, a C-terminal alpha-1 antitrypsin fragment, that we found to be elevated in septic patients and to apply this peptide as diagnostic marker for infectious and noninfectious etiologies of SIRS. Incubation of human polymorphonuclear neutrophils with synthetic CAAP48, the SNP-variant CAAP47, and several control peptides revealed intense neutrophil activation, induction of neutrophil chemotaxis, reduction of neutrophil viability, and release of cytokines. We determined the abundance of CAAP48 in patients with severe sepsis, severe SIRS of noninfectious origin, and viral infection. CAAP48 levels were 3-4-fold higher in patients with sepsis compared to SIRS of noninfectious origin and allowed discrimination of those patients with high sensitivity and specificity. Our results suggest that CAAP48 is a promising discriminatory sepsis biomarker with immunomodulatory functions, particularly on human neutrophils, supporting its important role in the host response and pathophysiology of sepsis.

Abstract
BACKGROUND Health care-associated infections (HAIs) can be associated with increased health care costs. We examined extra length of hospital stay (LOS) and associated per diem costs attributable to HAIs in a large academic medical center. METHODS Data for analysis were acquired in a preinterventional phase of a prospective cohort study (ALERTS) conducted over 12 months in 27 general and 4 intensive care units at Jena University Hospital. HAIs were identified among patients hospitalized for ≥48 hours with at least 1 risk factor for HAI and new antimicrobial therapy; the diagnosis was confirmed by U.S. Centers for Disease Control and Prevention criteria. Extra LOS was estimated by multistate modeling, and associated extra costs were based on average per diem costs for clinical units sampled. RESULTS Of a total of 22,613 patients hospitalized for ≥48 hours, 893 (3.95%) experienced 1,212 episodes of HAI during 12 months. The associated mean extra LOS ± SEM in general units was 8.45 ± 0.80 days per case and 8.09 ± 0.91 days for patients treated in both general and intensive care units. Additional costs attributable to HAIs were €5,823-€11,840 ($7,453-$15,155) per infected patient. CONCLUSION HAIs generated substantial extra costs by prolonging hospitalization. Potential clinical and financial savings may be realized by implementing effective infection prevention programs.

Abstract
BACKGROUND AND OBJECTIVES There are currently no reliable data on the differential use of renal replacement therapy (RRT) options for critically ill patients with acute renal failure in Germany. PATIENTS AND METHODS A questionnaire-based survey was delivered to 2265 German intensive care units. The questionnaire contained 19 questions regarding RRT. RESULTS A total of 423 German intensive care units participated in the survey. The offered modalities of RRT varied significantly: the smaller the facility, the fewer different RRT options were available. Intermittent dialysis procedures were available in only 35% of hospitals with up to 400 beds. In university hospitals, hemodynamically unstable patients were exclusively treated by continuous RRT, whereas in hospitals with up to 400 beds, intermittent RRT was also used. In addition, treatment practice was also dependent on the specialization of the treating physicians: Isolated acute renal failure was treated more often intermittently by nephrologists compared to anesthesiologists (79.7 vs. 43.3%). Nephrologists also used extracorporeal RRT more often in cardiorenal syndrome (54.3 vs. 35.8%), whereas anesthesiologists preferred them in sepsis (37.3 vs. 23.1%). The choice of anticoagulant varied as well: Hospitals with up to 400 beds offered regional citrate anticoagulation in only 50% compared to 90% of university hospitals. CONCLUSIONS Currently, RRT treatment in acute renal failure on German intensive care units seems to be dependent on the size, local structures, and education of the intensivists rather than patient needs. Our results demonstrate the necessity to establish cross-disciplinary standards for the treatment of acute renal failure in German intensive care units.

Abstract
BACKGROUND Purpura fulminans is a rare life-threatening condition which is characterized by disseminated thrombosis in dermal and systemic microcirculation, cutaneous hemorrhages with progressing necrosis and multiple organ failure. The underlying pathogenesis is based on the disruption of the intrinsic anticoagulation cascade, with protein C deficiency being considered the leading factor in this process. In the majority of cases, the condition emerges as consumptive coagulopathy associated with severe sepsis. OBJECTIVES Epidemiological data on sepsis-associated purpura fulminans (SAPF) are scarce and evidence-based treatment guidelines have not been established yet. While restoration of the balance in the coagulation cascade is a declared therapeutic goal, evaluations of the efficacy of different therapeutic approaches in randomized clinical trials are still lacking. The causal role of individual microbial pathogens also requires comprehensive evaluation. METHODS A prospective multicenter Sepsis-Associated Purpura Fulminans International Registry-Europe (SAPFIRE) will be established in the first quarter of 2015. For the first time, participating centers will systematically collect information on etiology, clinical course, biomarkers, treatment, morbidity, and mortality of SAPF. RESULTS The SAPFIRE data will be periodically evaluated and disseminated. Retrospective analysis of each center's data and regular access to aggregated information collected by other centers will enable the participants to monitor and update care quality standards.

Abstract
INTRODUCTION There are no reliable data on the structure and practice of the care of critically ill patients with acute renal failure in Germany. METHODS We carried out a detailed survey by sending a questionnaire to 2265 German Intensive Care Units. The questionnaire contained 19 questions regarding renal replacement therapy. RESULTS 423 German intensive care units participated in the survey. Most of the ICUs are headed interdisciplinary (47%) or by anesthesiologists (30%), with significant differences depending on the size of the clinic, with primarily interdisciplinary management in smaller clinics. The offered type of renal replacement therapy varies significantly, the smaller the house the fewer methods are available. Thus, intermittent dialysis procedures are offered only in 35% of hospitals with up to 400 beds. The indication for the initiation of acute renal replacement therapy in intensive care is provided predominantly (53%) by an anesthesiologist. A nephrologist is only involved in 22% of all intensive care units. The indication is based primarily on a "clinical criteria", but these are poorly defined. CONCLUSION Our results demonstrate the need for cross-disciplinary standards for the treatment of acute renal failure in German intensive care units.

Abstract
Background Sepsis sequelae include critical illness polyneuropathy, myopathy, wasting, neurocognitive deficits, post-traumatic stress disorder, depression and chronic pain. Little is known howlong-term sequelae following hospital discharge are treated. The aim of our study is to determine the effect of a primary care-based, long-term program on health-related quality of life in sepsis survivors. Methods/Design In a two-armed randomized multicenter interventional study, patients after sepsis (n = 290) will be assessed at 6, 12 and 24 months. Patients are eligible if severe sepsis or septic shock (ICD-10), at least two criteria of systemic inflammatory response syndrome (SIRS), at least one organ dysfunction and sufficient cognitive capacity are present. The intervention comprises 1) discharge management, 2) training of general practitioners and patients in evidence-based care for sepsis sequelae and 3) telephone monitoring of patients. At six months, we expect an improved primary outcome (health-related quality of life/SF-36) and improved secondary outcomes such as costs, mortality, clinical-, psycho-social- and process-of-care measures in the intervention group compared to the control group. Discussion This study evaluates a primary care-based, long-term program for patients after severe sepsis. Study results may add evidence for improved sepsis care management. General practitioners may contribute efficiently to sepsis aftercare. Trial registration U1111-1119-6345. DRKS00000741, CCT-NAPN-20875 (25 February 2011).

Abstract
HISTORY AND ADMISSION FINDINGS A 82 year-old man was admitted with a facial Herpes zoster reactivation and a zoster-related meningoencephalitis. He was treated with Aciclovir over a peripheral venous catheter that was placed in the right elbow pit. The meningoencephalitis subsided without neurological deficits, but the patient developed a catheter-associated phlebitis. An oral cephalosporin was prescribed and the patient discharged. After developing a fever and general discomfort he was readmitted to hospital three days later. INVESTIGATIONS A 3 × 3 cm abscess in the elbow pit was incised and drained, but no swab or blood cultures were taken. When the patient's condition got worse an echocardiogram was ordered. It showed vegetations on the aortic and mitral valves as well as on the cardiac pacemaker wires. TREATMENT AND COURSE Blood cultures were positive for Enterococcus faecalis. Although a therapy with vancomycin and ampicillin was started, the patient's condition impaired. Surgical valve replacement was initiated, but the patient expired 5 weeks later due to septic multi-organ failure. CONCLUSION The danger of peripheral venous catheter infections is frequently underrated, early identification of the causing pathogen, sensitivity testing and proper antibiotic treatment are of tremendous importance. Clinical sings of sepsis must under no circumstances be overlooked.

Abstract
BACKGROUND AND AIM Health care associated infections (HAIs) are one of the most frequent complications of hospital care, associated with increased morbidity, mortality and considerable extra costs for the health care system. The overarching objective of the ALERTS study is to demonstrate the feasibility of a hospitalwide programme to reduce the burden of HAIs and related sepsis of at least 20 %. METHODS Prospective, quasi-experimental study covering all acute care units (27 general wards, 4 ICUs, overall 809 beds) at Jena University Hospital. Surveillance for HAIs is performed by computerized antibiotic monitoring in patients with risk factors for HAIs (i. e. intravenous and urinary catheters, surgery) on a daily basis. Following the first surveillance period a multifaceted, pragmatic infection control programme, aimed at proper hand hygiene and bundles for the prevention of the four most common HAIs will be implemented. Subsequently, a second surveillance period lasting 18 months will be conducted to measure the effect of the infection control programme, starting in May 2013. RESULTS Interim results for the first surveillance period (09/2011 to 08/2012) are presented. During this period, 30,631 patients were admitted to the participating departments. According to CDC definitions we identified 1,637 HAIs, resulting in an overall incidence of 5.3 %. Based on clinical evaluation only, irrespective of the CDC definitions, an additional 944 HAIs were detected (overall HAI rate, 8.4 % [n =2581]). A substantial proportion of patients had HAI associated severe sepsis or septic shock (lower respiratory tract infection, n = 279 [37 %]; surgical site infection, n = 114 [25 %]; primary sepsis, n = 110 [32 %]; urinary tract infection, n = 46 [8 %]; other, n = 87 [22 %]). CONCLUSION Our numbers reveal that a high number of HAIs are missed using CDC-definitions and therefore the magnitude of the problem might be underestimated. Furthermore, a high percentage of HAIs progress from localized infection to severe sepsis or septic shock, requiring ICU treatment.

Abstract
A case of severe chronic dysphagia lasting more than 1 year after long-term ventilation due to sepsis is presented. Fiber optic endoscopic examination of swallowing (FEES) revealed retention of food on both sides of the base of the tongue and in both valleculae combined with severe penetration and postglutitive aspiration into the larynx. The reason was a broad-based scarred adhesion between the lingual side of the epiglottis and the tongue base. The adhesion was resected using a CO(2) laser. The final examination 3 months later showed complete recovery of normal swallowing function.

Abstract
Nowadays, most patients in hospital die in the intensive care unit from sepsis and multiple organ failure. Clinical research in this critically ill and vulnerable patient population bears a lot of ethical and legal problems; however, it remains a must in order to develop evidence-based diagnostic and therapeutic strategies for life-threatening diseases with special respect to limited health care resources. With regard to the Declaration of Helsinki, good clinical practice guidelines (GCP) from the European Medicines Agency (EMA) and the German medical drug law (AMG) this article discusses ethical and legal aspects of patient inclusion for clinical trials as well as incentives for appropriate patient recruitment from an interdisciplinary point of view.

Abstract
The occurrence of systemic inflammatory response syndrome (SIRS) remains a major problem in intensive care units with high morbidity and mortality. The differentiation between noninfectious and infectious etiologies of this disorder is challenging in routine clinical practice. Many biomarkers have been suggested for this purpose; however, sensitivity and specificity even of high-ranking biomarkers remain insufficient. Recently, metabolic profiling has attracted interest for biomarker discovery. The objective of this study was to identify metabolic biomarkers for differentiation of SIRS/sepsis. A total of 186 meta-bolites comprising six analyte classes were determined in 143 patients (74 SIRS, 69 sepsis) by LC-MS/MS. Two markers (C10:1 and PCaaC32:0) revealed significantly higher concentrations in sepsis. A classification model comprising these markers resulted in 80% and 70% correct classifications in a training set and a test set, respectively.This study demonstrates that acylcarnitines and glycerophosphatidylcholines may be helpful for differentiation of infectious from noninfectious systemic inflammation due to their significantly higher concentration in sepsis patients. Considering the well known pathophysiological relevance of lipid induction by bacterial components, metabolites as identified in this study are promising biomarker candidates in the differential diagnosis of SIRS and sepsis.

Abstract
Practice guidelines are systematically developed statements and recommendations that assist the physicians and patients in making decisions about appropriate health care measures for specific clinical circumstances taking into account specific national health care structures. The 1st revision of the S-2k guideline of the German Sepsis Society in collaboration with 17 German medical scientific societies and one self-help group provides state-of-the-art information (results of controlled clinical trials and expert knowledge) on the effective and appropriate medical care (prevention, diagnosis, therapy and follow-up care) of critically ill patients with severe sepsis or septic shock. The guideline had been developed according to the “German Instrument for Methodological Guideline Appraisal” of the Association of the Scientific Medical Societies (AWMF). In view of the inevitable advancements in scientific knowledge and technical expertise, revisions, updates and amendments must be periodically initiated. The guideline recommendations may not be applied under all circumstances. It rests with the clinician to decide whether a certain recommendation should be adopted or not, taking into consideration the unique set of clinical facts presented in connection with each individual patient as well as the available resources.

Abstract
The high mortality and morbidity of severe sepsis and septic shock had not been reduced during the two recent decades, despite a number of advances in the field of supportive and adjunctive sepsis therapies. The reason might be that important steps towards overcoming of sepsis - early diagnosis, the surgical resection of the infectious focus and an adequate antibiotic treatment - at present are still suboptimal and have to be improved. However, worldwide growing resistances of pathogens against the common antibiotics are detected. In opposite, no major progress in the development of new antibiotics, mainly for the treatment of Gram-negative non-fermenter infections like Pseudomonas aeruginosa, can be predicted for the next years. Therefore, sepsis treatment must be focused on prevention of infection, and on an optimised application of current antibiotic substances. The key factors are a broad, high dose, and early applicated initial treatment, a de-escalation strategy according to the clinical course supported by the application of novel molecular markers, and - with exceptions - a limitation of treatment to 7 to 10 days. A closer cooperation between microbiologists, infection control specialists and clinical infectious disease consultants may be a key factor to overcome the raising problems in the future.

Abstract
Severe sepsis and septic shock have an increasing incidence but an unchanged mortality. It has been demonstrated that the time until the start of supportive therapy affects the progress of multiorgan failure and patient outcome. Early goal-directed therapy guided by central venous oxygen saturation is associated with a significant reduction in mortality, as is the use of lung-protective mechanical ventilation and recombinant activated protein C (rhAPC) in eligible patients. The use of starches for volume resuscitation, low-dose dopamine and hydrocortison as well as an intensive insulin protocol for restoration of euglycemia is not recommended. The German Competence Network Sepsis (SepNet) is currently studying further relevant questions.

Abstract
OBJECTIVE To investigate procalcitonin (PCT) levels in patients undergoing cardiopulmonary bypass (CPB) in order to assess the prevalence and prognostic capacity of elevated PCT levels following CPB in open heart surgery. DESIGN prospective observational study in consecutive patients. SETTING Twenty-four-bed ICU, department of thoracic and cardiovascular surgery, university hospital. PATIENTS Seven hundred and twenty two patients, 691 of whom underwent CPB, i.e., 476 had coronary bypass surgery (CABG), 130 valve replacement, 34 combined CABG and valve replacement and 23 thoracic aortic surgery. INTERVENTIONS Standard perfusion techniques were used with cardioplegic arrest and mild hypothermia (28-32 degrees C). With the exception of thoracic aortic procedures, full-flow perfusion was performed. MEASUREMENTS AND RESULTS PCT was measured prior to surgery and daily thereafter until ICU discharge or death. PCT significantly increased at day 1 postoperatively compared to baseline values (0.25+/-1.65 vs 6.49+/-22.0 ng/ml, p<0.005). However, in 55.1% of patients PCT was below 1.0 ng/ml. In 12.8% of CABG patients PCT was increased to >5.0 ng/ml, compared to 39% in valve patients and 35% of patients with aortic surgery. An elevated PCT level >1.0-5.0 ng/ml at day 1 was highly predictive of mortality (P<0.03, vs<1.0 ng/ml), with an additional accuracy when levels >5.0 ng/ml were measured (P<0.002 vs<1.0 ng/ml). CONCLUSIONS These results provide evidence that PCT might serve as an early prognostic marker in patients undergoing CPB in open heart surgery. It may be worth considering immunomodulating approaches in patients presenting elevated PCT levels in the early phase after CPB.

Abstract
OBJECTIVE To determine the value of procalcitonin (PCT) in the early diagnosis (and differentiation) of patients with SIRS, sepsis, severe sepsis, and septic shock in comparison to C-reactive protein (CRP), white blood cell and thrombocyte count, and APACHE-II score (AP-II). DESIGN Prospective cohort study including all consecutive patients admitted to the ICU with the suspected diagnosis of infection over a 7-month period. PATIENTS AND METHODS A total of 185 patients were included: 17 patients with SIRS, 61 with sepsis, 68 with severe sepsis, and 39 patients with septic shock. CRP, cell counts, AP-II and PCT were evaluated on the first day after onset of inflammatory symptoms. RESULTS PCT values were highest in patients with septic shock (12.89+/-4.39 ng/ml;P<0.05 vs patients with severe sepsis). Patients with severe sepsis had significantly higher PCT levels than patients with sepsis or SIRS (6.91+/-3.87 ng/ml vs 0.53+/-2.9 ng/ml;P<0.001, and 0.41+/-3.04 ng/ml;P<0.001, respectively). AP-II scores did not differ significantly between sepsis, severe sepsis and SIRS (19.26+/-1.62, 16.09+/-2.06, and 17.42+/-1.72 points, respectively), but was significantly higher in patients with septic shock (29.27+/-1.35,P<0.001 vs patients with severe sepsis). Neither CRP, cell counts, nor the degree of fever showed significant differences between sepsis and severe sepsis, whereas white blood cell count and platelet count differed significantly between severe sepsis and septic shock. CONCLUSIONS In contrast to AP-II, PCT appears to be a useful early marker to discriminate between sepsis and severe sepsis.

Abstract
In the commentary by Zander et al. the authors appear concerned about the methods and results of our, at that time, unpublished sepsis trial evaluating hydroxyethyl starch (HES) and insulin therapy. Unfortunately, the authors' concerns are based on false assumptions about the design, conduct and modes of action of the compounds under investigation. For instance, in our study the HES solution was not used for maintenance of daily fluid requirements, so that the assumption of the authors that this colloid was used "exclusively" is wrong. Moreover, the manufacturer of Hemohes, the HES product we used, gives no cut-off value for creatinine, thus the assumption that this cut-off value was "doubled" in our study is also incorrect. Other claims by the authors such as that lactated solutions cause elevated lactate levels, iatrogenic hyperglycemia and increase O(2) consumption are unfounded. There is no randomized controlled trial supporting such a claim - this claim is neither consistent with our study data nor with any credible published sepsis guidelines or with routine practice worldwide. We fully support open scientific debate. Our study methods and results have now been published after a strict peer-reviewing process and this data is now open to critical and constructive reviewing. However, in our opinion this premature action based on wrong assumptions and containing comments by representatives of pharmaceutical companies does not contribute to a serious, unbiased scientific discourse.

Abstract
A recent survey conducted by the publicly funded Competence Network Sepsis (Sep- Net) reveals that severe sepsis and/or septic shock occurs in 75,000 inhabitants (110 out of 100,000) and sepsis in 79,000 inhabitants (116 out of 100,000) in Germany annually. This illness is responsible for approx. 60,000 deaths and ranges as the third most frequent cause of death after acute myocardial infarction. Direct costs for the intensive care of patients with severe sepsis alone amount to approx. 1.77 billion euros, which means that about 30% of the budget in intensive care is used to treat severe sepsis. However, until now German guidelines for the diagnosis and therapy of severe sepsis did not exist. Therefore, the German Sepsis Society initiated the development of guidelines which are based on international recommendations by the International Sepsis Forum (ISF) and the Surviving Sepsis Campaign (SSC) and take into account the structure and organisation of the German health care system. Priority was given to the following guideline topics: a) diagnosis, b) prevention, c) causative therapy, d) supportive therapy, e) adjunctive therapy. The guidelines development process was carefully planned and strictly adhered to according to the requirements of the Working Group of Scientific Medical Societies (AWMF).

Abstract
These guidelines are intended to give evidence-based recommendations for the use of enteral nutrition (EN) in patients with chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD). They were developed by an interdisciplinary expert group in accordance with officially accepted standards and are based on all relevant publications since 1985. They have been discussed and accepted in a consensus conference. EN by means of oral nutritional supplements (ONS) or tube feeding (TF) enables nutritional intake to be maintained or increased when normal oral intake is inadequate. No data are yet available concerning the effects of EN on cachexia in CHF patients. However, EN is recommended to stop or reverse weight loss on the basis of physiological plausibility. In COPD patients, EN in combination with exercise and anabolic pharmacotherapy has the potential to improve nutritional status and function. Frequent small amounts of ONS are preferred in order to avoid postprandial dyspnoea and satiety as well as to improve compliance.

Abstract
Early diagnosis of the different severities of septic inflammation is important for early implementation of specific therapies. Sepsis and severe sepsis are accompanied by clinical and laboratory signs of systemic inflammation. However, patients suffering from non-infectious inflammation may present with similiar signs and symptoms making it difficult to diagnose infection based on clinical findings alone. Bacteriological evidence of sepsis, though definitive and specific, may not be obtainable, is time-consuming and even may not occur concurrently with clinical signs of sepsis. It is therefore important to identify markers, which, by enabling an early diagnosis of sepsis and organ dysfunction, would allow early specific therapeutic interventions. Wheras C-reactive Protein is a more sensitive parameter for the diagnosis of non-systemic infections, Procalcitonin seems to be a useful parameter to improve the diagnosis and monitoring of therapy in patients with severe sepsis and septic shock.
