Background. Causes of death due to severe injuries are both injuries incompatible with life and severe bleedings. Trauma-induced coagulopathy is usually found in 46 % of patients at the scene and in 60 % of individuals upon admission to the hospital. The purpose of the study was to establish the relationship between systemic inflammatory response syndrome (SIRS) and vascular-platelet and coagulation hemostasis parameters in patients with polytrauma. Materials and methods. We completed a prospective observational study and included 20 patients aged 19 to 55 years with polytrauma who were admitted to the Department of Anesthesiology with Intensive Care at Lviv City Clinical Hospital No. 8. Patients’ state was evaluated according to the Injury Severity Score (ISS) and Acute Physiology and Chronic Health Evaluation (APACHE II) score. We also took into account the duration of SIRS, the length of intensive care unit (ICU) stay, and hospital stay. Stages of the study: the day of admission to ICU (d1), the third day (d3), the fifth day (d5). The major clinical markers evaluated were: SIRS parameters, vascular-platelet hemostasis (intravascular platelet activation, adrenaline- and adenosine diphosphate-induced platelet aggregation), coagulation hemostasis (international normalized ratio, activated partial thromboplastin time, level of total fibrinogen and D-dimers). Statistical analysis was performed using variation statistics methods. The correlation dependence was performed with Spearman’s rank correlation coefficient. We determined significance level (p), and the differences were considered statistically significant at p < 0.05. Results. We have found a significant (p < 0.05) positive correlation between discocytes to spherocytes ratio and the level of total fibrinogen on stage d1, as well as a tendency (p = 0.09) to the presence of a positive correlation between this ratio and the patient’s body temperature. There was a significant (p < 0.05) inverse correlation between this ratio and the patient’s health status according to APACHE II, and a direct significant (p < 0.05) correlation with the length of ICU stay, as well as trends to an inverse correlation with the severity of injuries according to ISS (p = 0.07) and to a direct correlation with the duration of SIRS (p = 0.12). Conclusions. Patients with polytrauma had a significant (p < 0.05) positive correlation between the discocytes to spherocytes ratio and level of total fibrinogen, a tendency (p = 0.09) to a positive correlation between this ratio and the patient’s body temperature, a significant (p < 0.05) inverse correlation with the patient’s health status according to APACHE II, a direct significant (p < 0.05) correlation with the length of ICU stay, a trend (p = 0.07) to an inverse correlation with the severity of injuries according to ISS and a tendency (p = 0.12) to a direct correlation with duration of SIRS.

Background: The Japanese Guidelines for the Diagnosis and Treatment of Deep-Seated Mycosis were established in 2003. Proven Candida infection (CI) is defined as at least one positive blood culture yielding a Candida species. Clinically documented CI requires documentation of more than 2 sites of colonization and a positive plasma β-O-glucan test. Possible CI is diagnosed by one of the above criteria in febrile, nonneutropenic critically ill patients. Objective: To assess the use of definitions of clinically documented and possible CI for guiding preemptive antifungal therapy in critically ill patients. Methods: The patients treated in our intensive care unit (ICU) for at least 48 hours between 2000 and 2004 were investigated. The administration of antifungal agents and ICU mortality were compared among proven, clinically documented, and possible CI groups for age, sex, APACHE II score, diagnosis, length of ICU stay, treatment, number of colonization sites, and plasma β-D-glucan level. Results: Six patients were diagnosed with proven CI, 25 were diagnosed with clinically documented CI, and 104 with possible CI. The patients with clinically documented CI were compared with those with possible CI, and statistically significant differences were found in the following variables: APACHE II score (p = 0.018), length of ICU stay (p < 0.01), use of ventilator (p = 0.027), tracheotomy (p = 0.027), number of colonization sites (p < 0.001), plasma β-D-glucan level (p < 0.001), and administration of antifungal agents (p < 0.001); incidence of mortality was not statistically significant (p = 0.33). The shorter length of ICU stay, use of ventilator, and continuous hemodiafiltration were risk factors for death after adjusting for APACHE II score, admission before/after 2003, antifungal therapy, and other factors. Although the frequency of the administration of preemptive antifungal therapy was higher after 2003 than before, the mortality rate did not differ significantly, Conclusions: The use of the definitions of clinically documented and possible CI may be beneficial for determining when it is appropriate to initiate preemptive antifungal therapy. However, use of the guidelines did not lead to prevention of possible CI proceeding to clinically documented CI or to improved mortality.

Background: There have been numerous scores intended to evaluate the severity of patients’ condition upon admission and during their intensive care unit (ICU) stay. However, to our knowledge, no study has ever evaluated the predictive abilities of these scores among nosocomial patients during their ICU stay. The aim of our study is to compare the predictive performances of the Acute Physiology, and, Chronic Health Evaluation (APACHE II) score, Simplified Acute Physiologic Score (SAPS II), Logistic Organ Dysfunction (LOD), and Sequential Organ Failure Assessment (SOFA) scores among intensive care patients who have developed a nosocomial infection. Methods: The study is monocentric and retrospective. The APACHE II, SAPS II, LOD, and SOFA scores were reported from the third day of the patient’s hospital stay, preceding the diagnosis of the first nosocomial event up to the third post diagnosis day. Results: Out of 46 patients contracting at least one ICU-acquired infection, the multiple analyses indicated that on the day of diagnosis, the SOFA score is the most predictive (odds ratio [OR]: 12.3; 95% confidence interval [CI]: 2.33–64.91). The second most predictive was the APACHE II score (OR: 8.29; 95% CI: 1.43–48.14). The third and fourth most predictive were the LOD score (OR: 4.06; 95% CI: 0.81–20.26) and the SAPS II score (OR: 2.26; 95% CI: 0.55–9.24), respectively. Conclusion: The analysis of the receiver operating characteristic areas under the curve of the reported scores in the present study showed that the best predictive performance is in favor of the SOFA score.

Background.No information is available about the financial impact of central venous catheter (CVC)-associated bloodstream infection (BSI) in Mexico.Objective.To calculate the costs associated with BSI in intensive care units (ICUs) in Mexico City.Design.An 18-month (June 2002 through November 2003), prospective, nested case-control study of patients with and patients without BSI.Setting.Adult ICUs in 3 hospitals in Mexico City.Patients and Methods.A total of 55 patients with BSI (case patients) and 55 patients without BSI (control patients) were compared with respect to hospital, type of ICU, year of hospital admission, length of ICU stay, sex, age, and mean severity of illness score. Information about the length of ICU stay was obtained prospectively during daily rounds. The daily cost of ICU stay was provided by the finance department of each hospital. The cost of antibiotics prescribed for BSI was provided by the hospitals' pharmacy departments.Results.For case patients, the mean extra length of stay was 6.1 days, the mean extra cost of antibiotics was $598, the mean extra hospital cost was $11,591, and the attributable extra mortality was 20%.Conclusions.In this study, the duration of ICU stay for patients with central venous catheter-associated BSI was significantly longer than that for control patients, resulting in increased healthcare costs and a higher attributable mortality. These conclusions support the need to implement preventive measures for hospitalized patients with central venous catheters in Mexico.

Abstract Background Prognostication is an essential tool for risk adjustment and decision making in the intensive care units (ICUs). In order to improve patient outcomes, we have been trying to develop a more effective model than Acute Physiology and Chronic Health Evaluation (APACHE) II to measure the severity of the patients in ICUs. The aim of the present study was to provide a mortality prediction model for ICUs patients, and to assess its performance relative to prediction based on the APACHE II scoring system. Methods We used the Medical Information Mart for Intensive Care version III (MIMIC-III) database to build our model. After comparing the APACHE II with 6 typical machine learning (ML) methods, the best performing model was screened for external validation on anther independent dataset. Performance measures were calculated using cross-validation to avoid making biased assessments. The primary outcome was hospital mortality. Finally, we used TreeSHAP algorithm to explain the variable relationships in the extreme gradient boosting algorithm (XGBoost) model. Results We picked out 14 variables with 24,777 cases to form our basic data set. When the variables were the same as those contained in the APACHE II, the accuracy of XGBoost (accuracy: 0.858) was higher than that of APACHE II (accuracy: 0.742) and other algorithms. In addition, it exhibited better calibration properties than other methods, the result in the area under the ROC curve (AUC: 0.76). we then expand the variable set by adding five new variables to improve the performance of our model. The accuracy, precision, recall, F1, and AUC of the XGBoost model increased, and were still higher than other models (0.866, 0.853, 0.870, 0.845, and 0.81, respectively). On the external validation dataset, the AUC was 0.79 and calibration properties were good. Conclusions As compared to conventional severity scores APACHE II, our XGBoost proposal offers improved performance for predicting hospital mortality in ICUs patients. Furthermore, the TreeSHAP can help to enhance the understanding of our model by providing detailed insights into the impact of different features on the disease risk. In sum, our model could help clinicians determine prognosis and improve patient outcomes.

Objective To compare the outcomes of patients with and without a mean serum potassium (K+) level within the recommended range (3.5–4.5 mEq/L). Methods This prospective cohort study involved patients admitted to the medical intensive care unit (ICU) of Siriraj Hospital from May 2012 to February 2013. The patients’ baseline characteristics, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, serum K+ level, and hospital outcomes were recorded. Patients with a mean K+ level of 3.5 to 4.5 mEq/L and with all individual K+ values of 3.0 to 5.0 mEq/L were allocated to the normal K+ group. The remaining patients were allocated to the abnormal K+ group. Results In total, 160 patients were included. Their mean age was 59.3±18.3 years, and their mean APACHE II score was 21.8±14.0. The normal K+ group comprised 74 (46.3%) patients. The abnormal K+ group had a significantly higher mean APACHE II score, proportion of coronary artery disease, and rate of vasopressor treatment. An abnormal serum K+ level was associated with significantly higher ICU mortality and incidence of ventricular fibrillation. Conclusion Critically ill patients with abnormal K+ levels had a higher incidence of ventricular arrhythmia and ICU mortality than patients with normal K+ levels.

• Background Ventilator-associated pneumonia is a significant cause of morbidity and mortality and may be influenced by oral health. • Objective To describe the relationship between ventilator-associated pneumonia and oral health status, changes in oral health status during the first 7 days after intubation, and microbial colonization of the oropharynx and trachea. • Methods A total of 66 patients were enrolled within 24 hours of intubation and were followed up for up to 7 days. Data on oral health measures and the Clinical Pulmonary Infection Score (CPIS) were collected at baseline, day 4 (n = 37), and day 7 (n = 21). A regression model was used to predict risk of pneumonia at day 4. • ResultsDental plaque and oral organisms increased over time. Correlations were significant for baseline and day 4 dental plaque (P &lt; .001), baseline salivary lactoferrin and day 4 plaque (P = .01), and lower salivary volume and higher day 4 CPIS (P = .02). Potential pathogens were identified in oral cultures for 6 patients before or at the same time as the appearance of the organisms in tracheal aspirates. Correlations were significant with day 4 CPIS for score on the Acute Physiology and Chronic Health Evaluation (APACHE) II (P = .007), day 4 salivary volume (P = .02), interaction of APACHE II score and day 1 CPIS (P&lt;.001), and interaction of day 1 CPIS and plaque (P=.01). • Conclusions Higher dental plaque scores confer greater risk for ventilator-associated pneumonia, particularly for patients with greater severity of illness. Salivary volume and lactoferrin may affect the risk.

Variable mortality rates have been reported for patients with rheumatic diseases admitted to an intensive care unit (ICU). Due to the absence of appropriate control groups in previous studies, it is not known whether the presence of a rheumatic disease constitutes a risk factor. Moreover, the accuracy of the Acute Physiology and Chronic Health Evaluation II (APACHE II) score for predicting outcome in this group of patients has been questioned. The primary goal of this study was to compare outcome of patients with rheumatic diseases admitted to a medical ICU to those of controls. The records of all patients admitted between 1 April 2003 and 30 June 2014 (n=4020) were screened for the presence of a rheumatic disease during admission (n=138). The diagnosis of a rheumatic disease was by standard criteria for these conditions. An age- and gender-matched control group of patients without a rheumatic disease was extracted from the patient population in the database during the same period (n=831). Mortality in ICU, in hospital and after 180 days did not differ significantly between patients with and without rheumatic diseases. There was no difference in the performance of the APACHE II score for predicting outcome in patients with rheumatic diseases and controls. This score, as well as a requirement for the use of inotropes or vasopressors, accurately predicted hospital mortality in the group of patients with rheumatic diseases. In conclusion, patients with a rheumatic condition admitted to intensive care do not do significantly worse than patients without such a disease.

AbstractPatients undergoing allogeneic hematopoietic stem cell transplantation have a high morbidity and mortality, especially after admission to intensive care unit (ICU) during peri-transplant period. The objective of this study was to identify new clinical and biological parameters and validate prognostic scores associated with ICU, short-and long-term survival. Significant differences between ICU survivors and ICU non-survivors for the clinical parameters invasive mechanical ventilation, urine output, heart rate, mean arterial pressure, and amount of vasopressors have been measured. Among prognostic scores (SOFA, SAPSII, PICAT, APACHE II, APACHE IV) assessing severity of disease and predicting outcome of critically ill patients on ICU, the APACHE II score has shown most significant difference (p = 0.002) and the highest discriminative power (area under the ROC curve (AUC) 0.74). An elevated level of lactate at day of admission was associated with poor survival on ICU and the most significant independent parameter (p < 0.001). In our cohort kidney damage with low urine output has a highly relevant impact on ICU, short- and long-term overall survival. The APACHE II score was superior predicting ICU mortality compared to all other tested prognostic scores for patients on ICU during peri-transplant period.
