Purpose: Chronic use of atypical antipsychotics may lead to metabolic abnormalities including hyperglycemia. Although evidence supports acute hyperglycemic episodes associated with atypical antipsychotic use, the acute use of atypical antipsychotics in the intensive care unit (ICU) setting has not been studied. The purpose of this study is to evaluate the occurrence of hyperglycemia in ICU patients receiving newly prescribed atypical antipsychotic. Summary: Of the 273 patient charts reviewed, 50 patients were included in this study. Approximately 45% of patients experienced at least 1 hyperglycemic episode (blood glucose >180 mg/dL) after the initiation of an atypical antipsychotic in the ICU. Of the patients experiencing at least 1 hyperglycemic episode, 60% experienced multiple distinct hyperglycemic episodes. In this study, quetiapine was the most commonly used atypical antipsychotic, 19 (38%) patients were discharged from the ICU on the atypical antipsychotic, 6 (12%) patients died in the ICU, and 31 (62%) patients were treated with an antihyperglycemic agent. Logistic regression analysis showed that women and ICU patients with a higher Acute Physiology and Chronic Health Evaluation II (APACHE II) score were significantly more likely to have multiple hyperglycemic episodes. Conclusion: Patients admitted to the ICU and initiated on an atypical antipsychotic may develop hyperglycemia independent of other glucose-elevating factors. The direct correlation of these agents to resulting acute hyperglycemia is unknown. Further studies are needed to investigate the link between atypical antipsychotics and acute hyperglycemia and the clinical significance of the impact on patient outcomes.

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.Bloodstream infections due to methicillin-resistant Staphylococcus aureus (MRSA) have been associated with significant risk of in-hospital mortality. The acute physiology and chronic health evaluation (APACHE) II score was developed and validated for use among intensive care unit (ICU) patients, but its utility among non-ICU patients is unknown. The aim of this study was to determine the ability of APACHE II to predict death at multiple time points among ICU and non-ICU patients with MRSA bacteremia.Design.Retrospective cohort study.Participants.Secondary analysis of data from 200 patients with MRSA bacteremia at 2 hospitals.Methods.Logistic regression models were constructed to predict overall in-hospital mortality and mortality at 48 hours, 7 days, 14 days, and 30 days using APACHE II scores separately in ICU and non-ICU patients. The performance of APACHE II scores was compared with age adjustment alone among all patients. Discriminatory ability was assessed using the c-statistic and was compared at each time point using X2 tests. Model calibration was assessed using the Hosmer-Lemeshow goodness-of-fit test.Results.APACHE II was a significant predictor of death at all time points in both ICU and non-ICU patients. Discrimination was high in all models, with c-statistics ranging from 0.72 to 0.84, and was similar between ICU and non-ICU patients at all time points. APACHE II scores significantly improved the prediction of overall and 48-hour mortality compared with age adjustment alone.Conclusions.The APACHE II score may be a valid tool to control for confounding or for the prediction of death among ICU and non-ICU patients with MRSA bacteremia.

Abstract Background : Currently, there is limited data of large databases of acute kidney injury (AKI) epidemiology from Southeast Asia, especially in Indonesia, the biggest countries in. Therefore, we aimed to provide demographic data of intensive care unit (ICU) patients with AKI and the utilization of renal replacement therapy (RRT) in Indonesia. Methods : We collected demographic and clinical data from 952 ICU patients. Patients were classified into AKI and non-AKI. AKI was classified according to the Kidney Disease Improving Global Outcome (KDIGO) criteria in three stages. We then assess the Acute Physiology and Chronic Health Evaluation (APACHE) II score of AKI and non-AKI patients. RRT modalities were listed down by the number of procedures conducted. Results : Overall incidence of AKI was 43%, distributed among three stages: 18.5 % stage 1, 33% stage 2, 48.5 % stage 3. Patients developing AKI need mechanical ventilation more often in comparison with non-AKI. Patients with AKI have an average APACHE score of 16.5, while non-AKI patients have an average score of 9.9. Among AKI patients, 24.6% requires RRT. The most common RRT modalities were intermittent hemodialysis (69.4%), followed by slow low efficiency dialysis (22.1%), continuous renal replacement therapy (4.2%), and peritoneal dialysis (1.1%). Conclusions: This study showed that AKI is a common problem in Indonesian ICU with containing a high mortality rate. We strongly believe that identification the risk factor of AKI will provide the opportunity to develop the predictability score for AKI prevention and finally improve AKI outcome.

Background: Intensive care unit (ICU) environment disrupts the circadian rhythms due to environmental and other nonphotic synchronizers. The main purpose of this article is to establish whether critically patients have desynchronization at the molecular level after 1 week of stay in the ICU. Methods: The rhythm of Clock, Bmal1, Cry1, and Per2 genes in neuro-ICU patients (n = 11) on the first day after admission in the unit (1 day) and 1 week later (1 week) was studied, 4 time points throughout the day, at 6, 12, 18, and 24 hours. Human whole blood samples were obtained from neuro-ICU patients. The total RNA was isolated and each sample was reverse transcribed to complementary DNA and quantitative polymerase chain reaction (PCRq) was performed. The possible rhythm was studied using Fourier Series. Results: After 1 week, the clock gene rhythmicity completely disappeared. Messenger RNA (mRNA) expression for the 4 clock genes was shown rhythmicity at the first day after admission in the ICU. Circadian rhythmicity for none of them was observed but rather, ultradian rhythmicity was found. The expression of Clock, Bmal1, and Per2 mRNA after 1 week was similar in the 4-time point studies without significant fluctuation among the 4 time points analyzed. Discussion: Rhythmic mRNA expression is present at the first day after admission in the ICU. However, ICU stay during 1 week affects the molecular machinery of the biological clock generating chronodisruption. Circadian disruption is associated with the risk of several pathologies, thus, it seems to be clear that ICU stay in constant conditions could adversely affect patient evolution and probably, circadian resynchronization restoring clock gene expression could lead to a better clinical evolution of the patient. Conclusions: Clock genes disruption is observed in neuro-ICU patients. Light therapy as well as melatonin treatment could reduce the impact of ICU stay period in biological clock, thereby improving patients’ recovery.

PURPOSE: To assess the ability of the Acute Physiology and Chronic Health Evaluation II (APACHE II) to stratify the severity of illness and the impact of delay transfer to an Intensive Care Unit (ICU) on the mortality of surgical critically ill patients. METHODS: Five hundred and twenty-nine patients (60.3% males and 39.7% females; mean age of 52.8 ± 18.5 years) admitted to the ICU were retrospectively studied. The patients were divided into survivors (n=365) and nonsurvivors (n=164). APACHE II and death risk were analysed by generation of receiver operating characteristic (ROC) curves. The interval time between referral and ICU arrival was also registered. The level of significance was 0.05. RESULTS: The mean APACHE II and death risk was 19.9 ± 9.6 and 37.7 ± 28.9%, respectively. The area under the ROC curve for APACHE II and death risk was 0.825 (CI = 0.765-0.875) and 0.803 (CI = 0.741-0.856). The overall mortality (31%) increased progressively with the delay time to ICU transfer, as also evidencied by the APACHE II score and death risk. CONCLUSION: This investigation shows that the longer patients wait for ICU transfer the higher is their criticallity upon ICU arrival, with an obvious negative impact on survival rates.

The Impact

Severe muscle wasting is a debilitating condition in critically ill intensive care unit (ICU) patients, characterized by general muscle weakness and dysfunction, resulting in a prolonged mobilization, delayed weaning from the ventilator, and a decreased quality of life post-ICU. The mechanisms underlying limb muscle weakness in ICU patients are complex and involve the impact of primary disease, but also factors common to critically ill ICU patients such as sepsis, mechanical ventilation (MV), immobilization, and systemic administration of corticosteroids (CS). These factors may have additive negative effects on skeletal muscle structure and function, but their respective role alone remain unknown. The primary aim of this study was to examine how CS administration potentiates ventilator and immobilization-related limb muscle dysfunction at the gene level. Comparing biceps femoris gene expression in pigs exposed to MV and CS for 5 days with only MV pigs for the same duration of time showed a distinct deregulation of 186 genes according to microarray. Surprisingly, the decreased force-generation capacity at the single muscle fiber reported in response to the addition of CS administration in mechanically ventilated and immobilized pigs was not associated with an additional upregulation of proteolytic pathways. On the other hand, an altered expression of genes regulating kinase activity, cell cycle, transcription, channel regulation, oxidative stress response, cytoskeletal, sarcomeric, and heat shock protein, as well as protein synthesis at the translational level, appears to play an additive deleterious role for the limb muscle weakness in immobilized ICU patients.

Objectives.To measure the incidence of nosocomial infection (NI) among patients with septic shock according to the place of septic shock acquisition and to evaluate the increase in the risk of pulmonary infection associated with septic shock.Design.Prospective cohort study.Setting.TWO intensive care units (ICUs) of a French university hospital.Patients and Methods.The study included a total of 209 septic shock patients during the period December 1, 2001 through April 30, 2005. The place of septic shock acquisition for 108 patients was the community; for 87, the hospital; and for 14, the ICU. To evaluate the impact of septic shock on the development of pulmonary infection, a competitive and adjusted hazard ratio (aHR) model was applied to nontrauma ICU patients.Results.Among the 209 study patients, 48 (23%) experienced 66 NIs after septic shock. There was no significant difference in the NI attack rates according to place of acquisition: for the community acquisition group, 24 cases per 100 patients (95% confidence interval [CI], 16-32); for the hospital acquisition group, 20 cases per 100 patients (95% CI, 11-28); and for the ICU acquisition group, 36 cases per 100 patients (95% CI, 11-61) (P = .3). For nontrauma ICU patients, the presence of community-acquired septic shock was found to be independently associated with a higher incidence of pulmonary infection, compared with the absence of septic shock (aHR, 2.12 [95% CI, 1.08-4.16]; P = .03).Conclusions.The risk of NI did not differ by the place of septic shock acquisition. The risk of pulmonary infection was higher for ICU patients with community-acquired septic shock who were admitted for underlying nontrauma disease. Studies are needed to investigate the pathogenic mechanisms that facilitate pulmonary infection in this population, taking into account exposure to invasive devices and immunosuppression after the initial phase of septic shock.

Background Intensive care unit (ICU) patients are at high risk of anemia, and phlebotomy is a potentially modifiable source of blood loss. Our objective was to quantify daily phlebotomy volume for ICU patients, including blood discarded as waste during vascular access, and evaluate the impact of phlebotomy volume on patient outcomes. Methods This was a retrospective observational cohort study between September 2014 and August 2015 at a tertiary care academic medical-surgical ICU. A prospective audit of phlebotomy practices in March 2018 was used to estimate blood waste during vascular access. Multivariable logistic regression was used to evaluate phlebotomy volume as a predictor of ICU nadir hemoglobin < 80 g/L, and red blood cell transfusion. Results There were 428 index ICU admissions, median age 64.4 yr, 41% female. Forty-four patients (10%) with major bleeding events were excluded. Mean bedside waste per blood draw (144 draws) was: 3.9 mL from arterial lines, 5.5 mL central venous lines, and 6.3 mL from peripherally inserted central catheters. Mean phlebotomy volume per patient day was 48.1 ± 22.2 mL; 33.1 ± 15.0 mL received by the lab and 15.0 ± 8.1 mL discarded as bedside waste. Multivariable regression, including age, sex, admission hemoglobin, sequential organ failure assessment score, and ICU length of stay, showed total daily phlebotomy volume was predictive of hemoglobin <80 g/L (p = 0.002), red blood cell transfusion (p<0.001), and inpatient mortality (p = 0.002). For every 5 mL increase in average daily phlebotomy the odds ratio for nadir hemoglobin <80 g/L was 1.18 (95% CI 1.07–1.31) and for red blood cell transfusion was 1.17 (95% CI 1.07–1.28). Conclusion A substantial portion of daily ICU phlebotomy is waste discarded during vascular access. Average ICU phlebotomy volume is independently associated with ICU acquired anemia and red blood cell transfusion which supports the need for phlebotomy stewardship programs.

Abstract Background: The impact of liver cirrhosis on the outcomes of admission to intensive care unit (ICU) is not completely understood. Our purpose is to identify risk factors for mortality in ICU patients with liver cirrhosis. Methods: Using reimbursement claims from Taiwan’s National Health Insurance Research Database from in 2006-2012, 1,250,300 patients were identified as having ICU stays of more than one day, and 37,197 of these had liver cirrhosis. With propensity score-matching for socioeconomic status, pre-existing medical conditions, and cirrhosis-related morbidities, 37,197 ICU patients without liver cirrhosis were selected for comparison. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of cirrhosis associated with 30-day, ICU, and one-year mortality were calculated. Results: Compared with control, cirrhotic patients had higher 30-day mortality (aOR 1.60, 95% CI 1.53 to 1.68), particularly those with jaundice (aOR 2.23, 95% CI 2.03 to 2.45), ascites (aOR 2.32, 95% CI 2.19 to 2.46) or hepatic coma (aOR 2.21, 95% CI 2.07 to 2.36). Among ICU patients, liver cirrhosis was also associated with ICU mortality (aOR 144, 95% CI 1.38 to 1.51) and one-year mortality (aOR 1.40, 95% CI 1.35 to 1.46). Associations between cirrhosis of liver and increased 30-day mortality were significant in both sexes and every age group. Conclusions: Liver cirrhosis was associated with 30-day mortality in ICU patients. Jaundice, ascites, hepatic coma, more than 4 admissions due to cirrhosis, and more than 30 days of hospital stay due to cirrhosis were exacerbated factors in cirrhotic ICU patients.
