RESUMO
PURPOSE: Timely and accurate data on the epidemiology of sepsis are essential to inform policy decisions and research priorities. We aimed to investigate the validity of inpatient administrative health data (IAHD) for surveillance and quality assurance of sepsis care. METHODS: We conducted a retrospective validation study in a disproportional stratified random sample of 10,334 inpatient cases of age ≥ 15 years treated in 2015-2017 in ten German hospitals. The accuracy of coding of sepsis and risk factors for mortality in IAHD was assessed compared to reference standard diagnoses obtained by a chart review. Hospital-level risk-adjusted mortality of sepsis as calculated from IAHD information was compared to mortality calculated from chart review information. RESULTS: ICD-coding of sepsis in IAHD showed high positive predictive value (76.9-85.7% depending on sepsis definition), but low sensitivity (26.8-38%), which led to an underestimation of sepsis incidence (1.4% vs. 3.3% for severe sepsis-1). Not naming sepsis in the chart was strongly associated with under-coding of sepsis. The frequency of correctly naming sepsis and ICD-coding of sepsis varied strongly between hospitals (range of sensitivity of naming: 29-71.7%, of ICD-diagnosis: 10.7-58.5%). Risk-adjusted mortality of sepsis per hospital calculated from coding in IAHD showed no substantial correlation to reference standard risk-adjusted mortality (r = 0.09). CONCLUSION: Due to the under-coding of sepsis in IAHD, previous epidemiological studies underestimated the burden of sepsis in Germany. There is a large variability between hospitals in accuracy of diagnosing and coding of sepsis. Therefore, IAHD alone is not suited to assess quality of sepsis care.

BACKGROUND: Post-traumatic stress has been identified as a frequent long-term complication in survivors of critical illnesses after sepsis. Little is known about long-term trajectories of post-traumatic stress and potentially modifiable risk factors following the ICU stay. Study objective was to explore and compare different clinical trajectories of post-traumatic stress symptoms in sepsis survivors up to two years after discharge from ICU. METHODS: Data on post-traumatic stress symptoms by means of the Post-traumatic Symptom Scale (PTSS-10) were collected in sepsis survivors at one, six, 12 and 24 months after discharge from ICU. Data on chronic psychiatric diagnoses prior ICU were derived from the primary care provider's health records, and data on intensive care treatment from ICU documentation. Trajectories of post-traumatic symptoms were identified ex post, discriminating patterns of change and k-means clustering. Assignment to the trajectories was predicted in multinomial log-linear models. RESULTS: At 24 months, all follow-up measurements of the PTSS-10 were completed in N = 175 patients. Three clusters could be identified regarding clinical trajectories of PTSS levels: stable low symptoms (N = 104 patients [59%]), increasing symptoms (N = 45 patients [26%]), and recovering from symptoms (N = 26 patients [15%]). Patients with initially high post-traumatic symptoms were more likely to show a decrease (OR with 95% CI: 1.1 [1.05, 1.16]). Females (OR = 2.45 [1.11, 5.41]) and patients reporting early traumatic memories of the ICU (OR = 4.04 [1.63, 10]) were at higher risk for increasing PTSS levels. CONCLUSION: Post-traumatic stress is a relevant long-term burden for sepsis patients after ICU stay. Identification of three different trajectories within two years after ICU discharge highlights the importance of long-term observation, as a quarter of patients reports few symptoms at discharge yet an increase in symptoms in the two years following. Regular screening of ICU survivors on post-traumatic stress should be considered even in patients with few symptoms and in particular in females and patients reporting traumatic memories of the ICU.

BACKGROUND: Sepsis is a medical emergency with potentially life-threatening consequences. Patients play a crucial role in preventing and recognizing sepsis at an early stage. The understanding of risk groups' sepsis knowledge and their ability to use this knowledge to recognize sepsis as an emergency is incomplete. METHODS: We conducted a cross-sectional survey in Germany and included a sample of 740 persons stratified by age (< 60 years, ≥ 60 years), specific chronic diseases (e.g. diabetes, chronic diseases, cancer), and region (Berlin/Brandenburg vs. other federal states of Germany). Standardized questionnaires were administered by a market research institute through online, telephone, or face-to-face methods. We assessed sepsis knowledge through a series of questions and the ability to recognize sepsis as an emergency through five case vignettes. To identify predictors of sepsis knowledge and the ability to recognize sepsis as a medical emergency, we conducted multiple linear regressions. RESULTS: Of the 36 items on sepsis knowledge, participants answered less than 50 per cent correctly (mean 44.1%; standard deviation (SD) 20.1). Most patients knew that sepsis is a defensive host response to infection (75.9%), but only 30.8% knew that vaccination can prevent infections that lead to sepsis. Across the five vignettes, participants identified sepsis as an emergency in only 1.33 of all cases on average (SD = 1.27). Sepsis knowledge was higher among participants who were older, female, and more highly educated and who reported more extensive health information seeking behaviour. The ability to recognize sepsis as an emergency was higher among younger participants, participants without chronic diseases, and participants with higher health literacy, but it was not significantly associated with sepsis knowledge. CONCLUSIONS: Risk groups showed low levels of knowledge regarding the preventive importance of vaccination and a low ability to recognize sepsis as a medical emergency. Higher levels of sepsis knowledge alone were not sufficient to improve the ability to identify sepsis as a medical emergency. It is crucial to develop effective educational strategies-especially for persons with lower education levels and infrequent health information seeking behaviour-that not only transfer but also facilitate the choice of appropriate actions, such as seeking timely emergency care.

BACKGROUND: Timely antimicrobial treatment and source control are strongly recommended by sepsis guidelines, however, their impact on clinical outcomes is uncertain. METHODS: We performed a planned secondary analysis of a cluster-randomized trial conducted from July 2011 to May 2015 including forty German hospitals. All adult patients with sepsis treated in the participating ICUs were included. Primary exposures were timing of antimicrobial therapy and delay of surgical source control during the first 48 h after sepsis onset. Primary endpoint was 28-day mortality. Mixed models were used to investigate the effects of timing while adjusting for confounders. The linearity of the effect was investigated by fractional polynomials and by categorizing of timing. RESULTS: Analyses were based on 4792 patients receiving antimicrobial treatment and 1595 patients undergoing surgical source control. Fractional polynomial analysis identified a linear effect of timing of antimicrobials on 28-day mortality, which increased by 0.42% per hour delay (OR with 95% CI 1.019 [1.01, 1.028], p ≤ 0.001). This effect was significant in patients with and without shock (OR = 1.018 [1.008, 1.029] and 1.026 [1.01, 1.043], respectively). Using a categorized timing variable, there were no significant differences comparing treatment within 1 h versus 1-3 h, or 1 h versus 3-6 h. Delays of more than 6 h significantly increased mortality (OR = 1.41 [1.17, 1.69]). Delay in antimicrobials also increased risk of progression from severe sepsis to septic shock (OR per hour: 1.051 [1.022, 1.081], p ≤ 0.001). Time to surgical source control was significantly associated with decreased odds of successful source control (OR = 0.982 [0.971, 0.994], p = 0.003) and increased odds of death (OR = 1.011 [1.001, 1.021]; p = 0.03) in unadjusted analysis, but not when adjusted for confounders (OR = 0.991 [0.978, 1.005] and OR = 1.008 [0.997, 1.02], respectively). Only, among patients with septic shock delay of source control was significantly related to risk-of death (adjusted OR = 1.013 [1.001, 1.026], p = 0.04). CONCLUSIONS: Our findings suggest that management of sepsis is time critical both for antimicrobial therapy and source control. Also patients, who are not yet in septic shock, profit from early anti-infective treatment since it can prevent further deterioration. Trial registration ClinicalTrials.gov ( NCT01187134 ).

BACKGROUND: Patient handover between prehospital care and the emergency department plays a key role in patient safety. Therefore, we aimed to create a validated tool for measuring quality of communication and interprofessional relations during handover in this specific setting. METHODS: Based on a theoretical framework a comprehensive item pool on information transfer and human factors in emergency department handovers was created and refined in a modified Delphi survey involving clinical experts. Based on a pre-test, items were again revised. The resulting Emergency Department Human Factors in Handover tool (ED-HFH) was validated in a field test at the emergency department of a German university hospital from July to December 2017. The ED-HFH was completed by emergency department and ambulance service staff participating in handovers and by an external observer. Description of item characteristics, exploratory factor analysis, analyses on internal consistency and interrater reliability by intraclass-correlation. Construct validity was analysed by correlation with an overall rating on quality of the handover. RESULTS: The draft of the ED-HFH contained 24 items, 90 of 102 eligible staff members participated in the field test completing 133 questionnaires on 38 observed handovers. Four items were deleted after analysis of item characteristics. Factor analysis supported a single factor explaining 39% of variance in the items. Therefore, a sum-score was calculated with a possible range between 14 and 70. The median value of the sum-score in the sample was 61.5, Cronbach's α was 0.83, intraclass-correlation was 0.52, the correlation with the overall rating of hand-over quality was ρ = 0.83 (p ≤ 0.001). CONCLUSIONS: The ED-HFH showed its feasibility, reliability and validity as a measure of quality of information transfer and human factors in handovers between ambulance services and the emergency department. It promises to be a useful tool for quality assurance and staff training.

OBJECTIVES: Worldwide, more than half of all sepsis cases occur in pediatric and adolescent patients, particularly in neonates. Previous population-based studies in these age groups often were limited to either neonatal or pediatric patients admitted to ICUs. We aimed to investigate the overall and age-specific incidence and case fatality of sepsis in children in Germany, a high-income country with a total population of 82 million. DESIGN: Retrospective observational study based on the German Diagnosis-related Groups statistics of the years 2010-2016. SETTING: All acute care hospitals in Germany except for prison and psychiatric hospitals. PATIENTS: Pediatric patients less than or equal to 19 years with International Classification of Diseases, 10th Revision-coded sepsis, neonates with International Classification of Diseases, 10th Revision-coded neonatal sepsis. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We analyzed pediatric sepsis incidence in patients aged birth to less than or equal to 19 years old, case fatality, and underlying comorbidities, and neonatal sepsis incidence and case fatality within the neonatal period. We identified 14,635 pediatric sepsis cases among 15.4 million pediatric hospitalizations between 2010 and 2016 (= 0.1% of pediatric hospitalizations). The incidence of pediatric sepsis was 14 cases per 100,000 children between 0 and 19 years. Case fatality was 16.6% and decreased from 17.8% (2010) to 15.0% (2016). A total of 11.5% of hospital deaths in the age group 0-19 years were associated with pediatric sepsis. Sepsis incidence and case fatality were highest in children less than 1 year old and declined in older children and adolescents. Admissions with pediatric sepsis were more common in children with preexisting comorbidities compared with those without (0.52% vs 0.03% of pediatric admissions). In neonates, the incidence of neonatal sepsis was 1,006 cases per 100,000 live births. Case fatality was 3.9%. While 17.7% of very low birth weight infants had neonatal sepsis, only 2.1% of low birth weight and 0.6% of normal birth weight neonates were affected, respectively. CONCLUSIONS: Sepsis is also in Germany a common and frequently fatal condition in pediatric patients, particularly among neonates and children with comorbidities.

BACKGROUND: Fever and hypothermia have been observed in septic patients. Their influence on prognosis is subject to ongoing debates. METHODS: We did a secondary analysis of a large clinical dataset from a quality improvement trial. A binary logistic regression model was calculated to assess the association of the thermal response with outcome and a multinomial regression model to assess factors associated with fever or hypothermia. RESULTS: With 6542 analyzable cases we observed a bimodal temperature response characterized by fever or hypothermia, normothermia was rare. Hypothermia and high fever were both associated with higher lactate values. Hypothermia was associated with higher mortality, but this association was reduced after adjustment for other risk factors. Age, community-acquired sepsis, lower BMI and lower outside temperatures were associated with hypothermia while bacteremia and higher procalcitonin values were associated with high fever. CONCLUSIONS: Septic patients show either a hypothermic or a fever response. Whether hypothermia is a maladaptive response, as indicated by the higher mortality in hypothermic patients, or an adaptive response in patients with limited metabolic reserves under colder environmental conditions, remains an open question. Trial registration The original trial whose dataset was analyzed was registered at ClinicalTrials.gov (NCT01187134) on August 23, 2010, the first patient was included on July 1, 2011.

BACKGROUND: Sepsis is a substantial health care burden. Data on regional variation in sepsis incidence in Germany and any possible associations with regional socioeconomic deprivation and health care capacity is lacking. METHODS: Ecological study based on the nationwide hospital Diagnosis-related Groups (DRG) statistics data of 2016. We identified sepsis by ICD-10-codes and calculated crude and age-standardized incidence proportions in the 401 administrative German districts. Associations between socioeconomic and health care capacity indicators and crude and age-adjusted sepsis incidence were investigated by simple and multiple negative binomial (NB) regressions. RESULTS: In 2016, sepsis incidence was 178 per 100,000 inhabitants and varied 10-fold between districts. We found that the rate of students leaving school without certificate was significantly associated with crude and age-standardized explicit sepsis incidence in the simple and multiple NB regressions. While we observed no evidence for an association to the capacity of hospital beds and general practitioners, the distance to the nearest pharmacy was associated with crude- and age-standardized sepsis incidence. In the multiple regression analyses, an increase of the mean distance + 1000 m was associated with an expected increase by 21.6 [95% CI, 10.1, 33.0] (p < 0.001), and 11.1 [95% CI, 1.0, 21.2]/100,000 population (p = .026) after adjusting for age differences between districts. CONCLUSIONS: Residence in districts with lower socioeconomic status (e.g., less education) and further distance to pharmacies are both associated with an increased sepsis incidence. This warrants further research with individual-level patient data to better model and understand such dependencies and to ultimately design public health interventions to address the burden of sepsis in Germany.

OBJECTIVES: Perceiving nonbeneficial treatment is stressful for ICU staff and may be associated with burnout. We aimed to investigate predictors and consequences of perceived nonbeneficial treatment and to compare nurses and junior and senior physicians. DESIGN: Cross-sectional, multicenter paper-pencil survey on personal and work-related characteristics, perceived nonbeneficial treatment, burnout, and intention to leave the job. SETTING: Convenience sample of 23 German ICUs. SUBJECTS: ICU nurses and physicians. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 847 questionnaires were returned (51% response); 778 had complete data for final multivariate analyses. Nonbeneficial treatment was in median perceived "sometimes." Adjusted for covariates, it was perceived more often by nurses and junior physicians (both p ≤ 0.001 in comparison to senior physicians), while emotional exhaustion was highest in junior physicians (p ≤ 0.015 in comparison to senior physicians and nurses), who also had a higher intention to leave than nurses (p = 0.024). Nonbeneficial treatment was predicted by high workload and low quality collaboration with other departments (both p ≤ 0.001). Poor nurse-physician collaboration predicted perception of nonbeneficial treatment among junior physicians and nurses (both p ≤ 0.001) but not among senior physicians (p = 0.753). Nonbeneficial treatment was independently associated with the core burnout dimension emotional exhaustion (p ≤ 0.001), which significantly mediated the effect between nonbeneficial treatment and intention to leave (indirect effect: 0.11 [95% CI, 0.06-0.18]). CONCLUSIONS: Perceiving nonbeneficial treatment is related to burnout and may increase intention to leave. Efforts to reduce perception of nonbeneficial treatment should improve the work environment and should be tailored to the different experiences of nurses and junior and senior physicians.

RESUMO
BACKGROUND: Communication is a hallmark of end-of-life care in the intensive care unit. It may influence the impact of end-of-life care on patients' relatives. We aimed to assess end-of-life care and communication from the perspective of intensive care unit staff and relate it to relatives' psychological symptoms. DESIGN: Prospective observational study based on consecutive patients with severe sepsis receiving end-of-life care; trial registration NCT01247792. SETTING/PARTICIPANTS: Four interdisciplinary intensive care units of a German University hospital. Responsible health personnel (attendings, residents and nurses) were questioned on the day of the first end-of-life decision (to withdraw or withhold life-supporting therapies) and after patients had died or were discharged. Relatives were interviewed by phone after 90 days. RESULTS: Overall, 145 patients, 610 caregiver responses (92% response) and 84 relative interviews (70% response) were analysed. Most (86%) end-of-life decisions were initiated by attendings and only 2% by nurses; 41% of nurses did not know enough about end-of-life decisions to communicate with relatives. Discomfort with end-of-life decisions was low. Relatives reported high satisfaction with decision-making and care, 87% thought their degree of involvement had been just right. However, 51%, 48% or 33% of relatives had symptoms of post-traumatic stress disorder, anxiety or depression, respectively. Predictors for depression and post-traumatic stress disorder were patient age and relatives' gender. Relatives' satisfaction with medical care and communication predicted less anxiety (p = 0.025). CONCLUSION: Communication should be improved within the intensive care unit caregiver team to strengthen the involvement of nurses in end-of-life care. Improved communication between caregivers and the family might lessen relatives' long-term anxiety.

INTRODUCTION: Current sepsis guidelines recommend antimicrobial treatment (AT) within one hour after onset of sepsis-related organ dysfunction (OD) and surgical source control within 12 hours. The objective of this study was to explore the association between initial infection management according to sepsis treatment recommendations and patient outcome. METHODS: In a prospective observational multi-center cohort study in 44 German ICUs, we studied 1,011 patients with severe sepsis or septic shock regarding times to AT, source control, and adequacy of AT. Primary outcome was 28-day mortality. RESULTS: Median time to AT was 2.1 (IQR 0.8 - 6.0) hours and 3 hours (-0.1 - 13.7) to surgical source control. Only 370 (36.6%) patients received AT within one hour after OD in compliance with recommendation. Among 422 patients receiving surgical or interventional source control, those who received source control later than 6 hours after onset of OD had a significantly higher 28-day mortality than patients with earlier source control (42.9% versus 26.7%, P <0.001). Time to AT was significantly longer in ICU and hospital non-survivors; no linear relationship was found between time to AT and 28-day mortality. Regardless of timing, 28-day mortality rate was lower in patients with adequate than non-adequate AT (30.3% versus 40.9%, P < 0.001). CONCLUSIONS: A delay in source control beyond 6 hours may have a major impact on patient mortality. Adequate AT is associated with improved patient outcome but compliance with guideline recommendation requires improvement. There was only indirect evidence about the impact of timing of AT on sepsis mortality.

BACKGROUND: There is an ongoing debate as to whether death with sepsis is primarily caused by sepsis or, more often, by the underlying disease. There are no data on the influence of a researcher's background on such an assessment. Therefore, the aim of this analysis was to assess the cause of death in sepsis and the influence of an investigator's professional background on such an assessment. MATERIALS AND METHODS: We performed a retrospective observational cohort study of sepsis patients treated in the medical intensive care unit (ICU) of a tertiary care center. For deceased patients, comorbidities and severity of illness were documented. The cause of death (sepsis or comorbidities or both combined) was independently assessed by four assessors with different professional backgrounds (medical student, senior physician in the medical ICU, anesthesiological intensivist, and senior physician specialized in the predominant comorbidity). RESULTS: In all, 78 of 235 patients died in hospital. Agreement between assessors about cause of death was low (κ 0.37, 95% confidence interval 0.29-0.44). Depending on the assessor, sepsis was the sole cause of death in 6-12% of cases, sepsis and comorbidities in 54-76%, and comorbidities alone in 18-40%. CONCLUSIONS: In a relevant proportion of patients with sepsis treated in the medical ICU, comorbidities contribute significantly to mortality, and death from sepsis without relevant comorbidities is a rare event. Designation of the cause of death in sepsis patients is highly subjective and may be influenced by the professional background of the assessor.

This study assessed differences in interprofessional collaboration, perception of nonbeneficial care, and staff well-being between critical care and palliative care teams. In six German hospitals, a staff survey was conducted between December 2013 and March 2015 among nurses and physicians in intensive and palliative care units. To allow comparability between unit types, a matching was performed for demographic characteristics of staff. N = 313 critical care and 79 palliative care staff participated, of which 72 each were successfully matched. Critical care nurses perceived the poorest overall quality of collaboration compared with critical care physicians and palliative care physicians and nurses. They also reported less inclusive leadership from attendings and head nurses, and the least collaboration on care decisions with physicians. They were most likely to perceive nonbeneficial care, and they reported the lowest levels of job satisfaction and the highest intention to leave the job. In partial correlations, aspects of high-quality collaboration were associated with less perceived nonbeneficial care and higher staff well-being for both critical care and palliative care staff. Our findings indicate that critical care teams could improve collaboration and enhance well-being, particularly among nurses, by adopting principles of collaborative work culture as established in palliative care.
RESUMO
BACKGROUND: Sepsis is a life-threatening organ dysfunction due to a dysregulated host response to infection. Annually, sepsis leads to approx. 90.000 deaths in Germany. Risk factors include amongst others older age (>60), innate or acquired dysfunction of the immune system, and underlying chronic diseases of the lung, heart, liver, or kidneys. The manifestation of sepsis is a medical emergency, and patient outcomes depend on timely diagnosis and immediate treatment. In addition, vaccinations e.g., against pneumococci or influenza virus, are a highly effective public health tool to prevent the most common underlying infections that may lead to sepsis. However, a lack of public awareness for the relevance of vaccination and detecting sepsis as an emergency underlines the need for public health interventions that address these issues. SepWiss aims to evaluate the effects of a multimodal information campaign designed to address this lack of awareness among the risk population in Germany. METHODS: SepWiss is an intervention at state level, consisting of a multimodal information campaign targeting risk groups in the German federal states of Berlin and Brandenburg (intervention region). Based on available evidence, various information formats were developed and implemented by outdoor advertising, social media, educational formats and through stakeholders' platforms, starting in August 2021. The control region comprises of the remaining 14 German federal states. We will analyze vaccination coverage (primary outcome), and sepsis knowledge, the ability to detect sepsis as an emergency, and attitude towards vaccination (secondary outcomes) amongst the risk population in a controlled before-after comparison. The implementation is accompanied by a mixed-method process evaluation. DISCUSSION: SepWiss is the first project of its kind to evaluate a complex multi-faceted evidence-based information campaign with regards to the topics of vaccination coverage, and the importance of sepsis detection and prevention for the most vulnerable populations in Germany. Results will be valuable for informing further nationwide campaigns. TRIAL REGISTRATION: German Registry for Clinical Trials: DRKS00024475. Registered February 24th, 2021.

Over the past several decades, dental health products containing fluoride have been widely employed to mitigate tooth decay and promote oral hygiene. However, concerns regarding the potential toxicological repercussions of fluoride exposure have incited continuous scientific inquiry. The current study investigated the cytotoxicity of sodium fluoride (NaF) and xylitol (Xyl), both individually and in combination, utilizing human keratinocyte (HaCaT) and osteosarcoma (SAOS-2) cell lines. In HaCaT cells, NaF decreased proliferation in a concentration-dependent manner and induced apoptosis-related morphological changes at low concentrations, whereas Xyl exhibited dose-dependent cytotoxic effects. The combination of NaF and Xyl reduced cell viability, particularly at higher concentrations, accompanied by apoptosis-like morphological alterations. Sub-cytotoxic NaF concentrations (0.2%) significantly affected caspase activity and the expression of pro-apoptotic genes. Conversely, Xyl demonstrated no discernible effect on these biological parameters. In SAOS-2 cells, NaF increased proliferation at high concentrations, contrasting with Xyl's concentration-dependent cytotoxic effects. The combination of NaF and Xyl had a minimal impact on cell viability. Sub-cytotoxic NaF concentrations did not influence caspase activity or gene expression, while Xyl induced dose-dependent morphological alterations, increased caspase activity, and upregulated pro-apoptotic gene expression. In ovo experiments on the chorioallantoic membrane (CAM) revealed that only NaF induced irritant effects, suggesting potential vascular adverse outcomes. This study advocates for the combined use of NaF and Xyl, highlighting their cytotoxicity benefits in healthy cells while maintaining safety considerations for tumor cells.

OBJECTIVES: To determine clinical outcomes of synthetic colloids, tetrastarch, and gelatin, used before and after cardiac surgery. DESIGN: Prospective observational cohort study. SETTING: Fifty-bed cardiac ICU. PATIENTS: Six thousand four hundred seventy-eight consecutive patients with cardiopulmonary bypass surgery. INTERVENTIONS: Fluid therapy in the operating room and on the ICU directed at preset hemodynamic goals: 1) hydroxyethyl starch (predominantly 6% hydroxyethyl starch 130/0.4) in 2004-2006, n = 2,137; 2) 4% gelatin in 2006-2008, n = 2,324; and 3) only crystalloids in 2008-2010, n = 2,017. MEASUREMENTS AND MAIN RESULTS: Renal replacement therapy was more common during periods when patients received synthetic colloids compared to only crystalloids. Risk of renal replacement therapy was greater after hydroxyethyl starch (odds ratio, 2.29; 95% CI, 1.47-3.60) and gelatin (odds ratio, 2.75; 95% CI, 1.84-4.16; both p < 0.001) compared to crystalloid. Propensity score stratification confirmed greater use of renal replacement therapy in the hydroxyethyl starch and gelatin periods compared to the crystalloid period (odds ratio, 1.46 [1.08, 1.97]; p = 0.013 and odds ratio, 1.72 [1.33, 2.24]; p < 0.001, respectively). Time to vasopressor cessation, normalization of serum lactate, and mean arterial pressure did not differ among groups. Total fluid requirement was 163 mL/kg in the hydroxyethyl starch period, 207 mL/kg in the gelatin period, and 224 mL/kg in the crystalloid period. Fluid intake was higher in the crystalloid group only during the first 20 hours. CONCLUSIONS: In cardiac surgery patients, fluid therapy with perioperative administration of synthetic colloids carries a high risk of renal replacement therapy and is not more effective than treating with only crystalloids.

Importance: Despite the large health burden, reliable data on sepsis epidemiology are lacking; studies using International Statistical Classification of Diseases and Related Health Problems (ICD)-coded hospital discharge diagnosis for sepsis identification suffer from limited sensitivity. Also, ICD data do not allow investigation of underlying pathogens and antimicrobial resistance. Objectives: To generate reliable epidemiological estimates by linking data from a population-based database to a reference standard of clinical medical record review. Design, Setting, and Participants: This was a retrospective, observational cohort study using a population-based administrative database including all acute care hospitals of the Scania region in Sweden in 2019 and 2020 to identify hospital-treated sepsis cases by ICD codes. From this database, clinical medical records were also selected for review within 6 strata defined by ICD discharge diagnosis (both with and without sepsis diagnosis). Data were analyzed from April to October 2022. Main outcomes and measures: Hospital and population incidences of sepsis, case fatality, antimicrobial resistance, and temporal dynamics due to COVID-19 were assessed, as well as validity of ICD-10 case identification methods compared with the reference standard of clinical medical record review. Results: Out of 295â¯531 hospitalizations in 2019 in the Scania region of Sweden, 997 patient medical records were reviewed, among which 457 had sepsis according to clinical criteria. Of the patients with clinical sepsis, 232 (51%) were female, and 357 (78%) had at least 1 comorbidity. The median (IQR) age of the cohort was 76 (67-85) years. The incidence of sepsis in hospitalized patients according to the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) criteria in 2019 was 4.1% (95% CI, 3.6-4.5) by medical record review. This corresponds to an annual incidence rate of 747 (95% CI, 663-832) patients with sepsis per 100â¯000 population. No significant increase in sepsis during the COVID-19 pandemic nor a decrease in sepsis incidence when excluding COVID-19 sepsis was observed. Few sepsis cases caused by pathogens with antimicrobial resistance were found. The validity of ICD-10-based case identification in administrative data was low. Conclusions and Relevance: In this cohort study of sepsis epidemiology, sepsis was a considerable burden to public health in Sweden. Supplying administrative data with information from clinical medical records can help to generate reliable data on sepsis epidemiology.

OBJECTIVE: To assess shock reversal and required fluid volumes in patients with septic shock. DESIGN: Prospective before and after study comparing three different treatment periods. SETTING: Fifty-bed single-center surgical intensive care unit. PATIENTS: Consecutive patients with severe sepsis. INTERVENTIONS: Fluid therapy directed at preset hemodynamic goals with hydroxyethyl starch (predominantly 6% hydroxyethyl starch 130/0.4) in the first period, 4% gelatin in the second period, and only crystalloids in the third period. MEASUREMENTS AND MAIN RESULTS: Main outcome was time to shock reversal (serum lactate <2.2 mmol/L and discontinuation of vasopressor use). Hemodynamic goals were mean arterial pressure >70 mm Hg; ScvO2 <70%; central venous pressure >8 mm Hg. Safety outcomes were acute kidney injury defined by Risk, Injury, Failure, Loss, and End-stage kidney disease criteria and new need for renal replacement therapy. Hemodynamic measures, serum lactate, and creatinine were comparable at baseline in all study periods (hydroxyethyl starch n = 360, gelatin n = 352, only crystalloids n = 334). Severity scores, hospital length of stay, and intensive care unit or hospital mortality did not differ significantly among groups. All groups showed similar time to shock reversal. More fluid was needed over the first 4 days in the crystalloid group (fluid ratios 1.4:1 [crystalloids to hydroxyethyl starch] and 1.1:1 [crystalloids to gelatin]). After day 5, fluid balance was more negative in the crystalloid group. Hydroxyethyl starch and gelatin were independent risk factors for acute kidney injury (odds ratio, 95% confidence interval 2.55, 1.76-3.69 and 1.85, 1.31-2.62, respectively). Patients receiving synthetic colloids received significantly more allogeneic blood products. CONCLUSIONS: Shock reversal was achieved equally fast with synthetic colloids or crystalloids. Use of colloids resulted in only marginally lower required volumes of resuscitation fluid. Both low molecular weight hydroxyethyl starch and gelatin may impair renal function.

OBJECTIVE: To gather data about structural and procedural characteristics of patient rounds in the intensive care unit (ICU) setting. DESIGN: A structured online survey was offered to members of two German intensive care medicine societies. MEASUREMENTS AND MAIN RESULTS: Intensivists representing 390 German ICUs participated in this study (university hospitals 25%, tertiary hospitals 23%, secondary hospitals 36%, primary hospitals 16%). In 90% of participating ICUs, rounds were reported to take place in the morning and cover an average of 12 intensive care beds and 6 intermediate care beds within 60â¯min. With an estimated bed occupancy of 80%, this averaged to 4.3â¯min spent per patient during rounds. In 96% of ICUs, rounds were stated to include a bedside visit. On weekdays, 86% of the respondents reported holding a second ICU round with the attendance of a qualified decision-maker (e.g. board-certified intensivist). On weekends, 79% of the ICUs performed at least one round with a decision-maker per day. In 18%, only one ICU round per weekend was reported, mostly on Sundays. The highest-qualified decision-maker present during rounds on most ICUs was an ICU attending (57%). Residents (96%) and intensive care nurses (87%) were stated to be always or usually present during rounds. In contrast, physiotherapists, respiratory therapists or medical specialists such as pharmacists or microbiologist were not regular members of the rounding team on most ICUs. In the majority of cases, the participants reported examining the medical chart directly before or during the bedside visit (84%). An electronic patient data management system (PDMS) was available on 31% of ICUs. Daily goals were always (55%) or usually (39%) set during rounds. CONCLUSION: This survey gives a broad overview of the structure and processes of ICU rounds in different sized hospitals in Germany. Compared to other mostly Anglo-American studies, German ICU rounds appear to be shorter and less interdisciplinary.
