Outcomes of septic cirrhosis patients admitted to the intensive care unit: A retrospective cohort study.

ABSTRACT: The aim of this study is to examine the outcome of septic patients with cirrhosis admitted to the intensive care unit (ICU) and predictors of mortality.Single center, retrospective cohort study.The study was conducted in Intensive care Department of King Abdulaziz Medical City, Riyadh, Saudi Arabia.Data was extracted from a prospectively collected ICU database managed by a full time data collector. All patients with an admission diagnosis of sepsis according to the sepsis-3 definition were included from 2002 to 2017. Patients were categorized into 2 groups based on the presence or absence of cirrhosis.The primary outcome of the study was in-hospital mortality. Secondary outcomes included ICU mortality, ICU and hospital lengths of stay and mechanical ventilation duration.A total of 7906 patients were admitted to the ICU with sepsis during the study period, of whom 497 (6.29%) patients had cirrhosis. 64.78% of cirrhotic patients died during their hospital stay compared to 31.54% of non-cirrhotic. On multivariate analysis, cirrhosis patients were at greater odds of dying within their hospital stay as compared to non-cirrhosis patients (Odds ratio {OR} 2.53; 95% confidence interval {CI} 2.04 - 3.15) independent of co-morbidities, organ dysfunction or hemodynamic status. Among cirrhosis patients, elevated international normalization ratio (INR) (OR 1.69; 95% CI 1.29-2.23), hemodialysis (OR 3.09; 95% CI 1.76-5.42) and mechanical ventilation (OR 2.61; 95% CI 1.60-4.28) were the independent predictors of mortality.Septic cirrhosis patients admitted to the intensive care unit have greater odds of dying during their hospital stay. Among septic cirrhosis patients, elevated INR and the need for hemodialysis and mechanical ventilation were associated with increased mortality.

Two-point compression ultrasonography: Enough to rule out lower extremity deep venous thrombosis?

BACKGROUND: Deep venous thrombosis (DVT) is a major cause of morbidity and is a common presenting complaint to the emergency department (ED). Point-of-care two-point compression ultrasonography has evolved as a quick and effective way of diagnosing DVT. The purpose of this study is to validate the prevalence and distribution of venous thrombi isolated to proximal lower extremity veins, other than common femoral and popliteal veins in patients with DVT. METHODS: This is a single-center retrospective study that looked at patients presenting to the ED of a tertiary care hospital between January 2014 and August 2018. The clinical presentation and laboratory and imaging results were obtained using the hospital's electronic medical record. RESULTS: A total of 2,507 patients underwent a lower extremity duplex ultrasound during the study period. Among them, 379 (15%) were included in the study. The percentages of isolated thrombi to the femoral vein and deep femoral vein were 7.92% and 0.53%, respectively. When the patients were stratified into the two groups of isolated DVT and two-point compression DVT, there were no statistically significant differences in the laboratory results between both groups. However, immobilized patients and patients with recent surgeries were more likely to have an isolated DVT. CONCLUSIONS: Thrombi isolated to proximal lower extremity veins other than the common femoral and popliteal veins make up 8.45% of DVTs. Given this significant number of missed DVTs, the authors recommend the addition of the femoral and deep femoral veins to the two-point compression exam.

Role of urine studies in asymptomatic febrile neutropenic patients presenting to the emergency department.

BACKGROUND: The role of urine studies in the detection of urinary tract infection (UTI) in febrile neutropenic patients with urinary symptoms (having a urinary catheter or having a positive urine analysis) is inarguable. However, the evidence is scarce regarding the indication for urine studies in asymptomatic (i.e., without urinary symptoms) patients with febrile neutropenia (FN) presenting to the emergency department (ED). The aim of this study is to evaluate the need for obtaining urine studies in asymptomatic febrile neutropenic patients. METHODS: This was a retrospective cohort study conducted on adult cancer patients who presented to the ED with FN and had no urinary symptoms. We included all ED presentations of eligible patients between January 2013 and September 2018. Student's t-test and Wilcoxon rank-sum test were used for continuous data, while Chi-square and Fisher's exact tests were used for categorical data. Participants were divided into two groups based on their urine culture (UC) results: negative and positive UCs. Two cut-offs were used for positive UC results: ≥105 cfu/mL and ≥104 cfu/mL. RESULTS: We included 284 patients in our study. The age of our patient population was 48.5±18.5 years. More than two-thirds (68.7%) of patients had severe neutropenia, while only 3.9% and 9.9% of the patients had positive UCs at ≥105 cfu/mL and ≥104 cfu/mL, respectively. UCs were expectedly positive in most patients with urinalysis (UA) abnormalities. However, 27.3% and 32.1% of patients with positive UCs at ≥105 cfu/mL and ≥104 cfu/mL respectively had a normal UA. CONCLUSIONS: In our study, the incidence of UTI in adult febrile neutropenic cancer patients who present to the ED without urinary symptoms is low. Consequently, routine urine testing may not be warranted in this population, as it adds unnecessary financial burdens on the patients and delays timely management.

Clinical Outcome of Septic Patients With Heart Failure With Preserved Ejection Fraction Presenting to the Emergency Department of a Tertiary Hospital: A Retrospective Cohort Study.

Background: Patients with heart failure with preserved ejection fraction (HFpEF) may be at a higher risk of mortality from sepsis than patients without heart failure. Objective: The aim of this study is to compare sepsis-related morbidity and mortality between patients with HFpEF and patients without heart failure presenting to the emergency department (ED) of a tertiary medical center. Design: Single-center retrospective cohort study conducted at an academic ED between January 1, 2015 and December 31, 2018. Patients: Patients with a diagnosis of sepsis were included. Main Measures: Bivariate and multivariate analyses were performed to look at differences in demographics, infection, and treatment parameters as well as outcomes of patients with sepsis. The primary outcome of the study was in-hospital mortality. Secondary outcomes included ED mortality, lengths of stay, and treatment differences between both groups. Key Results: A total of 1,092 patients presented with sepsis to the ED, of which 305 (27.93%) had HFpEF. There was no significant difference in in-hospital mortality between the two groups (40.7% vs. 37.4%; p = 0.314). However, there was a significant increase in ED mortality for septic HFpEF patients compared to non-heart failure patients (2.4 vs. 0.4%; p = 0.003). Septic HFpEF patients presenting to the ED were older than non-heart failure patients (76.84 vs. 68.44 years old; p < 0.0001). On the other hand, there was no significant increase in the use of vasopressors in the first 24 h between both groups. There was a significantly higher rate of intubation in the first 48 h for septic HFpEF patients (17.5 vs. 8.9%; p < 0.0001). Finally, there was significantly less intravenous fluid requirement at 6 h (1.94 L vs. 2.41L; p < 0.0001) and 24 h (3.11 L vs. 3.54L; p = 0.004) for septic patients with HFpEF compared to non-heart failure patients. Conclusion: Septic HFpEF patients experienced an increase in ED mortality, intubation, and steroid use compared to septic non-heart failure patients.

Serum Lactate as an Independent Predictor of In-Hospital Mortality in Intensive Care Patients.

PURPOSE: The aim of this study was to check if serum lactate was independently associated with mortality among critically ill patients. MATERIALS AND METHODS: This was a single-center, retrospective cohort study. All adult patients (>18 years of age) who had at least 1 measurement of lactate within 24 hours of admission to intensive care unit (ICU) between January 2002 and December 2017 were included in the analysis. Patients were stratified into 3 groups: those with a serum lactate of <2 mmol/L (normal level), 2 to 4 mmol/L (intermediate level), and >4 mmol/L (high level). The primary outcome was in-hospital mortality. Secondary outcomes included ICU and hospital lengths of stay and mechanical ventilation duration. To determine the association between lactate level and hospital mortality, bivariate and multivariate logistic regression analyses were performed. RESULTS: Of the 16,447 patients admitted to the ICU, 8167 (49.65%) had normal levels, 4648 (28.26%) had an intermediate, and 3632 (22.09%) had high lactate levels. Hospital mortality was the highest in high lactate level, followed by the intermediate and the normal level group (47.4% vs 26.5% vs 19.6%; P < .0001). Intermediate and high lactate levels were independent predictors of hospital mortality (odds ratio [OR], 1.32; 95% confidence interval [CI]: 1.20-1.46, and 1.94; 95% CI, 1.75-2.16, respectively) as well as ICU mortality (OR, 1.47; 95% CI, 1.30-1.66 and 2.56; 95% CI, 2.27-2.88, respectively). CONCLUSIONS: Intensive care unit serum lactate is associated with increased ICU and hospital mortality, independent of comorbidities, organ dysfunction, or hemodynamic status.

Characteristics and Outcomes of Pediatric Septic Patients With Cancer: A Retrospective Cohort Study.

BACKGROUND: Pediatric oncology patients may be at a higher risk of complications and mortality from sepsis compared with their nononcology counterpart. OBJECTIVES: The aim of this study is to compare characteristics, treatment, and sepsis-related mortality between oncology and nononcology patients presenting to the emergency department (ED). METHODS: This is a retrospective single-center cohort study including patients <18 years old with a diagnosis of sepsis, severe sepsis, septic shock, or bacteremia presenting to an academic ED between January 2009 and January 2015. A total of 158 patients were included with 53.8% having an underlying malignancy. The primary outcome of the study was in-hospital mortality. Secondary outcomes included ED vital signs, resuscitation parameters, laboratory work, infection site, general practitioner unit, intensive care unit length of stay, and hospital length of stay. RESULTS: Oncology patients had a higher in-hospital mortality (5.9% vs. 2.7%), however, it did not meet statistical significance (p = 0.45). On presentation, oncology patients had a lower respiratory rate (24.33 ± 9.48 vs. 27.45 ± 7.88; p = 0.04). There was a significant increase in the white blood count in oncology patients (4.011 ± 4.965 vs. 17.092 ± 12.806; p < 0.001) with this cohort receiving more intravenous fluids. In the first 6 hours (33.0 ± 27.7 mL/kg vs. 24.9 ± 16.1 mL/kg; p = 0.029) as well as having a higher percentage of vasopressor administration (15.3% vs. 1.4%; p = 0.002). Antibiotics were initiated at an earlier stage in the oncology cohort (1.25 ± 1.95 vs. 3.33 ± 1.97 hours; p < 0.0001). Cancer-free patients had a significantly higher rate of lung infections compared with cancer patients (68.5% vs. 32.9%; p < 0.0001). In terms of infection characteristics, cancer patients had a higher percentage of bacteremia (27.1% vs. 4.1%; p < 0.001). CONCLUSION: There was no statistical significance regarding mortality between the 2 cohorts. Pediatric cancer patients were found to have a higher incidence of bacteremia and received more aggressive treatment.

Corrected carotid flow time and passive leg raise as a measure of volume status.

BACKGROUND: The aim of this study was to investigate the value of corrected carotid flow time (FTc) with passive leg raise (PLR) as a non-invasive marker of volume status in end stage renal disease (ESRD) patients. METHODS: Prospective observational study of ESRD patients presenting to the Emergency department requiring hemodialysis. The common carotid artery was evaluated in long axis. Flow time measurements pre- and post-dialysis as well as before and after PLR were recorded. RESULTS: 54 patients were enrolled, of which, 30 (55%) were male. The mean age was 47.4 years. The mean volume of fluid removed was 3.89 ±â€¯0.91 L. In the pre-dialysis cohort, the mean FTc was 340.16 ms (95% CI, 330.36-349.95). Following PLR, the mean FTc was 341.34 ms (95% CI 331.74-350.94). In the post hemodialysis cohort, the mean FTc was 302.48 ms (95% CI, 293.63-311.32). Following the PLR maneuver, the mean FTc was 340.49 ms (95% CI 331.97-349.02). The mean decrease in corrected carotid flow time was 19.15 ms (95% CI, 22.86-41.17), 32.02 ms (95% CI 4.05-34.25) and 41.17 ms (95% CI, 36.47-54.76) for patients who had <3 L, 3-4 L and >4 L removed, respectively. In patients without CHF, the mean decrease in FTc after hemodialysis was 38.80 ms (95% CI, 30.12-47.49) whereas for CHF patients the mean decrease was 35.60 ms (95% CI, 25.05-46.15). CONCLUSION: Corrected flow time in conjunction with passive leg raise seem to correlate with volume status in hemodialysis patients.

Hemorrhagic shock from breast blunt trauma.

BACKGROUND: Seat belt use has been associated with decreased life-threatening thoracic injuries. However, there has been an increase in soft-tissue injuries such as breast trauma. CASE REPORT: We describe a case of a young healthy female who presented to a community hospital Emergency department without any trauma designation following a motor vehicle accident. The patient was found to have hemorrhagic shock from an intramammary hemorrhage and was treated with blood products and a temporizing external abdominal binder in preparation for a transfer to a level 1 center where she was successfully treated with angiographic embolization. OBJECTIVES: The objective of this study is to report on a case hemorrhagic shock from a breast hematoma as well as a review of the literature on previous seat belt associated breast trauma and its management in the emergency department. CONCLUSION: Seat belt associated breast trauma is uncommon in the emergency medicine literature. However, it can be associated with life threatening intramammary bleeding. Emergency physicians should be aware of these injuries and their proper management.

Descriptive analysis of sepsis in a developing country.

BACKGROUND: Most studies on sepsis were conducted in developed countries. The aim of this study is to report on a series of patients with sepsis in a tertiary hospital in a developing country. METHODS: Patients admitted through the emergency department of a single university-based institution between January 2008 and June 2012, with a final diagnosis of sepsis, bacteremia, or septic shock, were retrieved. A sample of 97 patients was selected. Vital signs at presentation, number of SIRS criteria, use of vasopressors and steroids, and in-hospital mortality were recorded. RESULTS: The mean age was 70.09 ± 16.82, ranging from 19 to 96 years; 48.5 % were females and 51.5 % were males; 42.3 % of the patients were found to be bacteremic. IV fluid requirement during the first 6 h was 1.75 ± 1.96 l. The time for antibiotic initiation was 3.43 ± 4.48 h, with 87.6 % of the antibiotics initiated in the emergency department. Norepinephrine was the most commonly used vasopressor (38.1 %) followed by dopamine (8.2 %), and the inotrope dobutamine (4.1 %); 45.3 % of the patients were admitted to the intensive care unit (ICU), and the remaining 54.7 % were managed on the general practice unit (GPU). A total of 30 (30.9 %) septic patients died. The 28-day mortality was 20.6 %. Deceased patients had greater vasopressor use, a longer stay in the ICU (p = 0.001), and a longer time to norepinephrine use (p = 0.004). CONCLUSIONS: This is the first study providing an in-depth analysis of sepsis patients in a developing country, looking at in-hospital mortality, SIRS criteria utility, and at the overall sepsis management.
