RESUMO
In January 2018 the recent revision of the S2k guidelines on calculated parenteral initial treatment of bacterial diseases in adults-update 2018 (Editor: Paul Ehrlich Society for Chemotherapy, PEG) was realized. It is a helpful tool for the complex infectious disease setting in an intensive care unit. The present summary of the guidelines focuses on the topics of anti-infective agents, including new substances, pharmacokinetics and pharmacodynamics as well as on microbiology, resistance development and recommendations for calculated drug therapy in septic patients. As in past revisions the recent resistance situation and results of new clinical studies are considered and anti-infective agents are summarized in a table.

Intensive care medicine is an important and integral part of internal medicine. Modern intensive care medicine permits survival of many patients with severe and life-threatening internal diseases in acute situations. Decisive for therapeutic success is often not the application of complicated and expensive medical technologies, but rather the rapid diagnosis and identification of core issues, with immediate and competent initiation of standard treatment regimens. An adequately staffed, well-organized interprofessional team is of central importance. With the application of standard therapies, it has been increasingly demonstrated that "less is more", and that personalized treatment concepts are better than aggressive strategies with higher therapeutic goals. In accordance with the Choosing wisely recommendations of the American societies for intensive care medicine, the extended board of the Deutsche Gesellschaft für Internistische Intensivmedizin und Notfallmedizin (DGIIN) has formulated five positive and five negative recommendations reflecting these principles. The current paper is an updated version of the manuscript originally published in the Deutsches Ärzteblatt. When applying these recommendations, it is important to consider that intensive care patients are very complex; therefore, the applicability of these principles must be assessed on an individual basis and, where necessary, modified appropriately.

INTRODUCTION: Tigecycline is an established treatment option for infections with multiresistant bacteria (MRB). It retains activity against many strains with limited susceptibility to other antibiotics. Efficacy and safety of tigecycline as monotherapy or in combination regimens were investigated in a prospective noninterventional study involving 1,025 severely ill patients in clinical routine at 137 German hospitals. MATERIALS AND METHODS: Data on the full population have been published; our present analysis focuses on infections caused by MRB. The study population included patients with complicated infections, high disease severity (APACHE II > 15: 65 %) and high MRB prevalence. Most patients had comorbidities, including cardiovascular disease, renal insufficiency, and/or diabetes mellitus. Treatment success was defined as cure/improvement without requirement of further antibiotic therapy. RESULTS: Pathogens isolated from 215 evaluable patients with documented MRB infections included 132 methicillin-resistant Staphylococcus aureus (MRSA), 42 vancomycin-resistant Enterococci (VRE) and 67 Gram-negative extended beta-lactamase (ESBL) producers. Of the MRB subpopulation, 140 patients received tigecycline monotherapy, 75 were treated with combination regimens. High overall clinical success rates were recorded for MRB infections treated with tigecycline alone (94 %) or in combinations (88 %); in detail intraabdominal infections (monotherapy: 90 %; combinations: 93 %), skin/soft tissue infections (93; 100 %), community-acquired pneumonia (100; 100 %), hospital-acquired pneumonia (94,7; 72,7 %), diabetic foot infections (89; 33 %), blood stream infections (100; 100 %) and multiple-site infections (92; 71 %). CONCLUSIONS: Tigecycline achieved high clinical success rates in patients with documented infections involving MRB strains despite high disease severity. These results add to the evidence indicating that tigecycline is a valuable therapeutic option for complicated infections in severely ill patients with a high likelihood of multidrug-resistant pathogen involvement.

INTRODUCTION: Hospital-acquired pneumonia (HAP) often occurring as ventilator-associated pneumonia (VAP) is the most frequent hospital infection in intensive care units (ICU). Early adequate antimicrobial therapy is an essential determinant of clinical outcome. Organisations like the German PEG or ATS/ IDSA provide guidelines for the initial calculated treatment in the absence of pathogen identification. We conducted a retrospective chart review for patients with HAP/VAP and assessed whether the initial intravenous antibiotic therapy (IIAT) was adequate according to the PEG guidelines. MATERIALS AND METHODS: We collected data from 5 tertiary care hospitals. Electronic data filtering identified 895 patients with potential HAP/VAP. After chart review we finally identified 221 patients meeting the definition of HAP/VAP. Primary study endpoints were clinical improvement, survival and length of stay. Secondary endpoints included duration of mechanical ventilation, total costs, costs incurred on the intensive care unit (ICU), costs incurred on general wards and drug costs. RESULTS: We found that 107 patients received adequate initial intravenous antibiotic therapy (IIAT) vs. 114 with inadequate IIAT according to the PEG guidelines. Baseline characteristics of both groups revealed no significant differences and good comparability. Clinical improvement was 64% over all patients and 82% (85/104) in the subpopulation with adequate IIAT while only 47% (48/103) inadequately treated patients improved (p< 0.001). The odds ratio of therapeutic success with GA versus NGA treatment was 5.821 (p<0.001, [95% CI: 2.712-12.497]). Survival was 80% for the total population (n = 221), 86% in the adequately treated (92/107) and 74% in the inadequately treated subpopulation (84/114) (p = 0.021). The odds ratio of mortality for GA vs. NGA treatment was 0.565 (p=0.117, [95% CI: 0.276-1.155]). Adequately treated patients had a significantly shorter length of stay (LOS) (23.9 vs. 28.3 days; p = 0.022), require significantly less hours of mechanical ventilation (175 vs. 274; p = 0.001), incurred lower total costs (EUR 28,033 vs. EUR 36,139, p = 0.006) and lower ICU-related costs (EUR 13,308 vs. EUR 18,666, p = 0.003). Drug costs for the hospital stay were also lower (EUR 4,069 vs. EUR 4,833) yet not significant. The most frequent types of inadequate therapy were monotherapy instead of combination therapy, wrong type of penicillin and wrong type of cephalosporin. DISCUSSION: These findings are consistent with those from other studies analyzing the impact of guideline adherence on survival rates, clinical success, LOS and costs. However, inadequately treated patients had a higher complicated pathogen risk score (CPRS) compared to those who received adequate therapy. This shows that therapy based on local experiences may be sufficient for patients with low CPRS but inadequate for those with high CPRS. Linear regression models showed that single items of the CPRS like extrapulmonary organ failure or late onset had no significant influence on the results. CONCLUSION: Guideline-adherent initial intravenous antibiotic therapy is clinically superior, saves lives and is less expensive than non guideline adherent therapy. Using a CPRS score can be a useful tool to determine the right choice of initial intravenous antibiotic therapy. The net effect on the German healthcare system per year is estimated at up to 2,042 lives and EUR 125,819,000 saved if guideline-adherent initial therapy for HAP/VAP were established in all German ICUs.

INTRODUCTION: The management of bloodstream infections especially sepsis is a difficult task. An optimal antibiotic therapy (ABX) is paramount for success. Procalcitonin (PCT) is a well investigated biomarker that allows close monitoring of the infection and management of ABX. It has proven to be a cost-efficient diagnostic tool. In Diagnoses Related Groups (DRG) based reimbursement systems, hospitals get only a fixed amount of money for certain treatments. Thus it's very important to obtain an optimal balance of clinical treatment and resource consumption namely the length of stay in hospital and especially in the Intensive Care Unit (ICU). We investigated which economic effects an optimized PCT-based algorithm for antibiotic management could have. MATERIALS AND METHODS: We collected inpatient episode data from 16 hospitals. These data contain administrative and clinical information such as length of stay, days in the ICU or diagnoses and procedures. From various RCTs and reviews there are different algorithms for the use of PCT to manage ABX published. Moreover RCTs and meta-analyses have proven possible savings in days of ABX (ABD) and length of stay in ICU (ICUD). As the meta-analyses use studies on different patient populations (pneumonia, sepsis, other bacterial infections), we undertook a short meta-analyses of 6 relevant studies investigating in sepsis or ventilator associated pneumonia (VAP). From this analyses we obtained savings in ABD and ICUD by calculating the weighted mean differences. Then we designed a new PCT-based algorithm using results from two very recent reviews. The algorithm contains evidence from several studies. From the patient data we calculated cost estimates using German National standard costing information for the German G-DRG system. We developed a simulation model where the possible savings and the extra costs for (in average) 8 PCT tests due to our algorithm were brought into equation. RESULTS: We calculated ABD savings of 4 days and ICUD reductions of -1.8 days. Our algorithm contains recommendations for ABX onset (PCT ≥ 0.5 ng/ml), validation whether ABX is appropriate or not (Delta from day 2 to day 3 ≥ 30% indicates inappropriate ABX) and recommendations for discontinuing ABX (PCT ≤ 0.25 ng/ml). We received 278,264 episode datasets where we identified by computer-based selection 3,263 cases with sepsis. After excluding cases with length of stay (LOS) too short to achieve the intended savings, we ended with 1,312 cases with ICUD and 268 cases without ICUD. Average length of stay of ICU-patients was 27.7 ± 25.7 days and for Non-ICU patients 17.5 ± 14.6 days respectively. ICU patients had an average of 8.8 ± 8.7 ICUD. - After applying the simulation model on this population we calculated possible savings of Euro -1,163,000 for ICU-patients and Euro -36,512 for Non-ICU patients. DISCUSSION: Our findings concerning the savings from the reduction of ABD are consistent with other publications. Savings ICUD had never been economically evaluated so far. Our algorithm is able to possibly set a new standard in PCT-based ABX. However the findings are based on data modelling. The algorithm will be implemented in 5-10 hospitals in 2012 and effects in clinical reality measured 6 months after implementation. CONCLUSION: Managing sepsis with daily monitoring of PCT using our refined algorithm is suitable to save substantial costs in hospitals. Implementation in clinical routine settings will show how much of the calculated effect will be achieved in reality.

INTRODUCTION: Severe infections require early optimization of antibiotic therapy. Since 2016, antibiotic susceptibility results with minimum inhibitory concentrations (MIC) direct from positive blood cultures are available in less than 8 h using a new diagnostic system. The aim of this study is to investigate the economic effects of a rapid availability of antibiotic susceptibility in Germany and to validate these theoretical results in a German hospital. MATERIALS AND METHODS: In the context of a literature search, the clinical and economic benefit of an adequate therapy as well as the rate of the initially inadequate antibiotic therapy (IIAT) were determined for sepsis and bloodstream infections. In addition to the weighted average of the pooled studies, the case numbers in Germany (data year 2015) of all DRGs for sepsis patients with coded pathogen and ICU stay were integrated into a theoretical economic model that was subsequently validated in a German hospital. RESULTS: The analysis of 14 studies with a total of 6408 patients showed an average weighted rate of 27.3% IIAT. From a total of 8 studies (nâ¯= 2988), an average weighted length of stay (LOS) saving of 4.7 days was determined with adequate initial therapy compared to an IIAT. In the theoretical model, an average of â¯1539 per case could be saved with a possible LOS reduction of 3.7 days. A conservative scenario with an IIAT of 20% and LOS reduction of 2.5 days still resulted in an average saving of 201 per case. In the hospital-individual model, 68% of 146 cases had a positive blood culture. In 61% of the examined cases an adjustment of the therapy would have been necessary (35% IIAT, 26% de-escalation). After deducting the cost of the test for 60 patients, the total potential savings amounted to â¯122,112, which is over 2000⯠per patient. CONCLUSION: A fast adequate antibiotic therapy was economically advantageous both in the economic model and in the real-life evaluation. The optimization of antibiotic therapy by early pathogen detection and MIC-based susceptibilities represents a possibility to achieve savings despite the high costs for diagnostics in the clinic. Particularly noteworthy is the optimization through de-escalation. The potential for each hospital should be identified through systematic case studies.

BACKGROUND: Healthcare workers are a high-risk population for SARS-CoV2 infection. For capacity planning of healthcare providers and to optimize protection of healthcare workers (HCW) in SARS-CoV2 pandemics, it is essential to know the risk of infection and potential immunity status of staff dealing with COVID-19 patients. MATERIALS AND METHODS: We examined seropravalence of SARS-CoV2 IgM/IgG antibodies (AB) in HCW of a region with the highest rate of infection (1570/100,000) during COVID-19 pandemic in Germany, 4 months after its start. Employees of a nonmedical company (MU) served as control group. Demographic data, medical history and working situation were recorded. RESULTS: A total of 1838 HCW and 986 MU volunteered to participate. Seroprevalence for SARS-CoV2 in HCW was 15.1% and 3.7% in MU. Among HCWs, nurses had a seropositivity of 20.0%, ICU personnel 20.3%, housekeepers 19.3%, physicians 12.0%, medical services (e.g., radiology, physiotherapy) 11.3%, administration 7.1% and technical services 6%. Symptoms typical for COVID-19 were not experienced by 10% of seropositive HCWs. CONCLUSION: Seroprevalence of SARS-CoV2 antibodies in HCW of a region heavily affected by COVID-19 is with 15.1% significantly higher than in a control group of nonmedical staff with 3.7%. Infection rate in HCW was higher in staff with close contact to infected patients. Seropositivity in ICU personnel is higher than in other clinical professions. The occupational risk for housekeepers seems to be underestimated.

INTRODUCTION: Procalcitonin (PCT) is a well-evaluated biomarker for the detection of severe bacterial infections and monitoring effectiveness of antibiotic therapy. This study aims to evaluate the usefulness of PCT in a clinical routine setting. MATERIALS AND METHODS: Of 358,763 clinical cases from 7 German hospitals in 2012 and 2013, 3854 cases had an ICD-10 code representing sepsis. A total of 1778 cases had pathologic PCT and one episode of infection. Of those, 671 showed a series of measures that was suitable to assess treatment success using PCT reduction. Propensity score matching was used to create two comparable groups with 211 patients in each group. RESULTS: The group with PCT reduction within 12 days showed a highly significant better proportion of survival (146/211 vs. 17/211; p < 0.0001). The odds ratio for death according to PCT reduction vs. nonreduction is 25.64 (p < 0.0001; 95 % CI: 14.49-45.45). PCT was normalized after an average of 6.2 days. DISCUSSION: The difference in survival implicates that PCT reduction is a suitable surrogate parameter to indicate successful antimicrobial therapy. Successful antibiotic therapy is a proven predictor for survival in sepsis. This study also showed concordant results in the group of patients with sepsis after abdominal surgery. Results from subgroup analyses confirm the initial findings. PCT reduction was used as surrogate for therapy success, as the antimicrobial therapy was not electronically available. CONCLUSION: PCT reduction is a strong predictor for survival. However, the data show that overall use of PCT to monitor sepsis therapy is not yet routinely established. Hospitals should establish algorithms for sepsis treatment that include PCT for the assessment of adequacy and the monitoring of success of the antimicrobial therapy.

The reimbursement of intensive care and nursing services in the German health system is based on the diagnosis-related groups (G-DRG) system. Due to the lack of a central hospital planning, the GDRG system has become the most important influence on the development of the German health system. Compared to other countries, intensive care in Germany is characterized by a high number of intensive care beds, a low nurse-to-patient ratio, no official definition of the level of care, and a minimal available data set from intensive care units (ICUs). Under the given circumstances, a shortage of qualified intensive care nurses and physicians is currently the largest threat for intensive care in Germany. To address these deficiencies, we suggest the following measures: (1) Integration of ICUs into the levels of care which are currently developed for emergency centers at hospitals. (2) Mandatory collection of structured data sets from all ICUs including quality criteria. (3) A reform of intensive care and nursing reimbursement under consideration of adequate staffing in the individual ICU. (4) Actions to improve ICU staffing and qualification.

OBJECTIVE: To evaluate the applicability of the Simplified Acute Physiology Score (SAPS II) for coronary care patients. DESIGN: Prospective observational cohort study. SETTING: Medical ICU of a community teaching hospital. PATIENTS: 1587 consecutive patients admitted over a period of 18 months. MEASUREMENTS AND MAIN RESULTS: Patients were divided in two groups according to the primary admission diagnosis: general medical intensive care (ICU) patients and intensive coronary care (CCU) patients. Score prediction was tested using criteria suitable to evaluate the discrimination and calibration properties of SAPS II. Mean SAPS II score was 31.6 (+/- 20.1) in ICU and 28.3 (+/- 15.5) in CCU patients (p = 0.06), mean risk of death 0.206 and 0.134 (p = 0.001), and observed hospital mortality 17.8 vs 10.3%. The area under the receiver operating characteristic curve was 0.888 in ICU and 0.908 in CCU patients (p = 0.5). The correlation between predicted and observed hospital mortality was 0.62 (p = 0.001) in ICU and 0.66 (p = 0.001) in CCU patients. The calibration curves did not differ from each other. The probability of death in survivors and nonsurvivors was equally distributed in ICU and CCU patients (p = 0.5). CONCLUSION: We conclude that SAPS II is applicable to CCU patients in our unit.

The efficacy and safety of ceftazidime and imipenem in patients with severe infections was compared in a randomized multi-centre trial. Patients on assisted respiration with clinical signs of pneumonia or septicaemia who had been in hospital for at least 3 days were studied. Twenty-one patients were treated with ceftazidime, 24 with imipenem. The mean duration of treatment was 9 days in both groups. At the end of the trial 17 patients (81%) of the ceftazidime group and 16 patients (67%) in the imipenem group were clinically cured or showed marked improvement. The bacteriological results showed an eradication of the causative pathogens in 17 of 21 cases in the ceftazidime group and 13 of 19 in the imipenem group.

AIM: The influence of substitution with two different amino acid solutions on changes in plasma amino acids were studied in patients with acute myocardial infarction. PATIENTS AND METHODS: Thirty consecutive patients admitted to an intensive care unit were included in this open, nonrandomized study. The isoleucine-phenylalanine-concentration ratio was calculated. Patients of the treatment groups received 10 ml/kg BW/24 h of 10% amino acid solutions intravenously (1 g/kg BW/24 h). Patients of group 1 received Intrafusin 10%, patients of group 2 Aminosteril 10%. Ten patients (group 3) were infused with 10 ml/kg BW/24 h isotonic electrolyte solution (Jonosteril and served as a control group. All infusions were performed over a 96 hour period. RESULTS: All infusion of amino acid solutions increased the plasma concentrations of most amino acids without a significant impact on the pattern of amino acids over time. Significant increases in plasma concentrations together with a significant variation over time were observed for glycine, isoleucine, proline, alpha-amino-butyric-acid and glutamine. A significant difference in relation to the type of amino acid solution was observed for isoleucine and proline (rapid increase and higher concentrations with Aminosteril), and glutamine (rapid increase and higher levels with Intrafusin). CONCLUSION: The isoleucine-phenylalanine-ratio increased from initially decreased values between 0.9 and 1.0 during amino acid infusion and reached the level of 1.25 found in healthy persons in patients with Intrafusin infusions.

Out of 724 patients admitted to the medical department of a community teaching hospital during three months 110 (14.5%) had electrocardiographically documented atrial fibrillation (AF). 56% had chronic and 44% intermittent AF. Only 66% of patients with AF suffered from diseases generally accepted as cause of AF, 29% had cardiovascular and pulmonary risk factors, 5% had lone AF. AF was already known in 66% of patients, in 21% AF was documented at the first time, only 14% were admitted because of AF, although AF was clearly the cause of symptoms in an additional 11%. The mean age of patients with AF (72 years) was higher than that of patients without AF. 95% of patients with AF suffered from more than one cardiovascular or pulmonary disease or risk factor (mean index of diseases of 3.2). Hospital mortality of patients with AF was much higher than mean total hospital mortality (19 vs 7.7) except in patients with lone AF. We conclude that AF is a marker of multimorbidity and bad prognosis in patients of general internal medicine.

171 consecutive patients of a medical intensive care unit (age 18 to 81 years, mortality 24.6%) who were treated in the ICU for at least 72 hours were investigated in order to test the hypothesis, that the combination of therapeutic scoring (TISS) and physiologic scoring (APS) may improve the prognostic significance of score systems and/or the severity of disease classification in critically ill patients. Discrimination of survivors and non-survivors of the combined score was comparable to the results of isolated scores. A higher weighting of the physiology parameters in the combined score did not improve its prognostic significance. On the other hand, only the combined score implicated a linear increase of mortality with increasing score point values. - We conclude, that the combined score system improves the severity of disease classification in critically ill medical patients.

All patients admitted to the ICU with acute myocardial infarction (MI) were treated by the same protocol since 1984. We report the results in Q-wave-MI of 1987 compared to 1984. Age (67.2 +/- 12.4 vs. 66.8 +/- 11.4 years), sex distribution (70.1% vs. 71.9% male), time elapse between begin of symptoms and admittance to the hospital (15.5 +/- 27.0 vs. 15.0 +/- 32.5 hours) were similar in both years, but the total number of definite Q-MI decreased by 22% from 135 (1984) to 105 (1987). Inhospital mortality (20% vs. 23%) and ICU mortality (14% vs. 20%) tended to decrease, although differences did not reach statistical significance. This was paralleled by an increase in the rate of i.v. thrombolytic therapy from 17% (1984) to 28% (1987) of all patients with Q-MI. The percentage of patients who definitely received i.v. thrombolysis when all indication criteria were present and all contraindicatory factors excluded increased from 47% (1984) to 97% (1987). We conclude, that the performance of i.v. thrombolysis in all patients, who fulfill the general accepted criteria for thrombolysis may improve clinical course and outcome in a given population of patients with acute Q-wave-infarction.

Septic encephalopathy is an early manifestation of sepsis. Changes in consciousness, focal or generalized seizures, multifocal myoclonus and/or varying hemiparesis are common clinical findings. All of these symptoms are reversible when sepsis has been successfully treated. Because there are no generally accepted criteria for the diagnosis of septic encephalopathy, it is a diagnosis of exclusion. We report the case of a 68-year-old patient who developed septic encephalopathy secondary to diarrhea and E. coli sepsis. In this case, symptoms of septic encephalopathy were fully reversed after the patient's E. coli sepsis had been adequately treated.

In anti-infective therapy, there is a need for objective diagnostic markers to guide the appropriate selection and duration of antibacterial treatment. In the diagnosis and treatment of bacterial infections, three aspects must be considered: the appropriateness of antibacterial therapy, the initiation and evaluation of an effective initial therapy, and termination of the antimicrobial treatment. Repetitive monitoring of procalcitonin (PCT) has been proposed as such a marker in conjunction with the clinical presentation and microbiological sampling of blood, urine, and/or sputum. Different threshold values for PCT in pulmonary infections vs. severe systemic infections (e.g., sepsis) have been proposed. However, a single PCT determination is not sufficient, only consecutive measurements can give feedback of the appropriateness and success of the antibacterial therapy. Furthermore, it is important to realize that besides bacterial infection, other disease states can elevate PCT levels. Examples are calcitonin-producing tumors, medullary C-cell thyroid carcinoma, and acute respiratory distress syndrome (ARDS). PCT can also be elevated in fungal infections. On the other hand, localized and encapsulated infections (e.g., abscess, endocarditis and early stages of infections) can be associated with lowered PCT values.

Intra-abdominal infections are generally the result of invasion and multiplication of enteric bacteria in the wall of a hollow viscus within the abdomen to produce peritonitis or abscess. When the infection extends into the peritoneal cavity or another normally sterile region of the abdominal cavity, the infection is described as a "complicated" intra-abdominal infection. Treatment of patients with complicated intra-abdominal infections involves antimicrobial therapy, generally in conjunction with an appropriate and timely surgical source control. Nearly all intra-abdominal infections are caused by multiple microorganisms that constitute the intestinal flora (aerobes and facultative and obligate anaerobes, with Enterobacteriaceae, enterococci and Bacteroides fragilis isolated most frequently). The emergence of drug resistance (e.g. ESBL-producing Enterobacteriaceae or resistant enterococci and staphylococci) poses a substantial threat to patients with surgical infections. Especially in patients with nosocomially acquired infections inadequate empiric antibiotic treatment is associated with treatment failure and death. In patients at risk broader spectrum antibiotic regimens with coverage of resistant Gram-negative bacilli and anaerobes and Gram-positive bacteria such as enterococci (including VRE) and staphylococci should be considered.
