Abstract Background: To clarify significance of the present National Clinical Database risk calculator (NCD-RC) for hepatectomy in Japan, relationship between perioperative parameters or outcomes in major hepatectomy and the mortality rate by NCD-RC was examined. Methods: Patient demographics, co-morbidity, surgical records, postoperative morbidity or mortality were examined and compared to the 30 days- or in-hospital-mortality rate among 55 patients with hepatobiliary diseases who underwent hemi- or more-extended hepatectomy and central (segment 458) hepatectomy. The cut-off percent for high risk mortality before hepatectomy was set at 5% in this period. Results: In-hospital morbidity over CD III was 17 (28%), The 30-day mortality and in-hospital mortality was nil and two (3%), respectively. Male patient showed significantly higher in-hospital mortality rate (p<0.01). In the 37 patients (group woML), mean age was 67.8±8.7 years old ranging 45 and 84. Others included A) with severe complications or mortality in whom low mortality rate (group wML, n=13), B) without severe complications neither mortality in whom high mortality rate (group woMH, n=7), and C) with severe complications or mortality in whom high mortality rate (group wMH, n=4 (6.5%)). Age, distribution of elderly patients, gender, the hepatobiliary diseases and the prevalence of preoperative co-morbidity were not significantly different between groups. In the group wML, the bile leakage was dominant and, however, the in-hospital death was not observed. In the group wMH, all operations were right hepatectomy with bile duct resection (RH-BDR) for biliary malignancy and two died of hepatic failure and, however, the prevalence of RH-BDR was not significantly higher in comparison with other groups. Conclusions: Predictive mortality rate by risk calculator under nationwide survey did not always match with patient outcomes in the actual clinical setting and further improvement will be required. In case of RH-BDR for biliary malignancy with high predictive rate, the careful perioperative managements is important under the present nationwide database.

Background: Relationship between outcomes of major hepatectomy and the mortality rate predicted by National Clinical Database risk calculator (NCD-RC) was examined . Methods: Patient demographics and postoperative morbidity and mortality were compared between 30-day and in-hospital mortality rates among 55 patients who underwent major hepatectomies . The cut-off value for high-risk mortality was set at 5%. Patients were divided into four groups: A) no severe complications and low predictive mortality rate (woML) , B) severe complications or mortality, and low mortality rate (wML) , C) no severe complications and high mortality rate (woMH) , and D) severe complications or mortality, and high mortality rate (wMH) . Results: Morbidity higher than CD III occurred in 17 patients (28%) and 30-day and in-hospital mortality in none and two (3%), respectively. The in-hospital mortality rate was significantly higher for male patients (p&lt;0.01). Age, elderly patients, diseases, and co-morbidity did not significantly differ among groups. Although bile leakage was common in group wML , there were no in-hospital deaths. All surgical procedures performed in group wMH were right hepatectomy with bile duct resection (RH-BDR) for biliary malignancy, and two died of hepatic failure; however, the incidence of RH-BDR was not significantly higher than those in other groups. Conclusions: Preoperative mortality rate predicted by NCD-RC was not always consistent with outcomes in actual clinical settings and further improvements are needed. In case of RH-BDR for biliary malignancy with high predictive mortality rate, careful decision making for liver function and perioperative management are required.

7025 Background: Patients (pts) with AML frequently encounter life-threatening complications requiring transfer to an intensive care unit (ICU). Methods: Retrospective analysis of 145 adults with AML requiring ICU admission at our tertiary cancer center 2018-19. Use of life-sustaining therapies (LSTs) and overall survival (OS) were reported using descriptive statistics. Logistic regression was used to identify risk factors for in-hospital death. Results: Median age was 64 yrs (range 18-86). 47% of pts had an ECOG status of ≥ 2 with a median of at least 1 comorbidity (Table). 117 pts (81%) had active leukemia at admission. 68 pts (47%) had poor-risk cytogenetics (CG) and 32 (22%) had TP53-mutated disease. 61 (42%), 27 (19%) and 57 pts (39%) were receiving 1st, 2nd and ≥ 3rd line therapy. 33 (23%) and 70 pts (48%) were receiving intensive and lower-intensity chemotherapy, respectively, and 77 pts (53%) were concurrently on venetoclax. Most common indications for admission were sepsis (32%), respiratory failure (24%) and leukocytosis (12%); Table outlines additional ICU admission details. Median OS from the date of ICU admission was 2.0 months (mo) for the entire cohort and 6.9, 1.6 and 1.2 mo in pts with favorable-, intermediate- and poor-risk CG. Median OS of pts receiving frontline vs. ≥ 2nd line therapy was 4.2 vs. 1.4 mo (P<0.001). Median OS in pts requiring 0-1 vs. 2-3 LSTs was 4.1 vs. 0.4 mo (P<0.001). OS was not different by age, co-morbidity burden nor therapy intensity. In a multivariate analysis that included SOFA scores, only adverse CG (OR 0.35, P = 0.028), and need for intubation with mechanical ventilation (IMV; OR 0.19, P = 0.009) were associated with increased odds of in-hospital mortality. Conclusions: A substantial portion of pts with AML survive their ICU admission with sufficient functionality to return home and receive subsequent therapy. In contrast to general medical populations, age, co-morbidities, and SOFA scores were not independently predictive of in-hospital mortality. Disease CG risk and the need for IMV were the strongest predictors of ICU survival. This suggests that many pts with AML can benefit from ICU care.[Table: see text]


Infective endocarditis (IE) is a condition that most commonly occurs in patients with pre-existing valve disease. It affects one in 30 000 people in the UK and is associated with a high mortality rate (15–30% in hospital mortality). Nurses working in the cardiac arena should be aware of those patients who are at risk of developing IE and its clinical management. This chapter covers the aetiology, diagnosis, complications, treatment, nursing considerations, and specific educational issues that are relevant to the overall management and prevention of IE.

SummaryThe management of acute pulmonary embolism (PE) is often challenging and requires specific medical expertise, diagnostic techniques and therapeutic options that may not be available in all hospitals throughout the entire week. The aim of our study was to evaluate whether or not an association exists between weekday or weekend admission and mortality for patients hospitalised with acute PE. Using routinely collected hospital administrative data, we examined patients discharged with a diagnosis of PE from the hospitals of the Emilia- Romagna Region in Italy (January 1999-December 2009). The risk of inhospital death was calculated for admissions at the weekend and compared to weekday admissions. Of a total of 26,560 PEs, 6,788 (25.6%) had been admitted during weekends. PE admissions were most frequent on Mondays (15.8%) and less frequent on Saturdays and Sun- days/holidays (12.8%) (p<0.001). Weekend admissions were associated with significantly higher rates of in-hospital mortality than weekday admissions (28% vs. 24.8%) (p<0.001). The risk of weekend admission and in-hospital mortality was higher after adjusting for sender, hospital characteristics, and the Charlson co-morbidity index. In conclusion, hospitalisation for PE on weekends seems to be associated with a significantly higher mortality rate than on weekdays. Further research is needed to investigate the reasons for this observed difference in mortality in order to try and implement future strategies that ensure an adequate level of care throughout the entire week.

(1) Background: Road traffic accidents (RTAs) are the leading cause of pediatric traumatic brain injury (TBI) and are associated with high mortality. Few studies have focused on RTA-related pediatric TBI. We conducted this study to analyze the clinical characteristics of RTA-related TBI in children and to identify early predictors of in-hospital mortality in children with severe TBI. (2) Methods: In this 15-year observational cohort study, a total of 618 children with RTA-related TBI were enrolled. We collected the patients’ clinical characteristics at the initial presentations in the emergency department (ED), including gender, age, types of road user, the motor components of the Glasgow Coma Scale (mGCS) score, body temperature, blood pressure, blood glucose level, initial prothrombin time, and the intracranial computed tomography (CT) Rotterdam score, as potential mortality predictors. (3) Results: Compared with children exhibiting mild/moderate RTA-related TBI, those with severe RTA-related TBI were older and had a higher mortality rate (p < 0.001). The in-hospital mortality rate for severe RTA-related TBI children was 15.6%. Compared to children who survived, those who died in hospital had a higher incidence of presenting with hypothermia (p = 0.011), a lower mGCS score (p < 0.001), a longer initial prothrombin time (p < 0.013), hyperglycemia (p = 0.017), and a higher Rotterdam CT score (p < 0.001). Multivariate analyses showed that the mGCS score (adjusted odds ratio (OR): 2.00, 95% CI: 1.28–3.14, p = 0.002) and the Rotterdam CT score (adjusted OR: 2.58, 95% CI: 1.31–5.06, p = 0.006) were independent predictors of in-hospital mortality. (4) Conclusions: Children with RTA-related severe TBI had a high mortality rate. Patients who initially presented with hypothermia, a lower mGCS score, a prolonged prothrombin time, hyperglycemia, and a higher Rotterdam CT score in brain CT analyses were associated with in-hospital mortality. The mGCS and the Rotterdam CT scores were predictive of in-hospital mortality independently.

Abstract Background Narrowing a large set of features to a smaller one can improve our understanding of the main risk factors for in-hospital mortality in patients with COVID-19. This study aimed to derive a parsimonious model for predicting overall survival (OS) among re-infected COVID-19 patients using machine-learning algorithms. Methods The retrospective data of 283 re-infected COVID-19 patients admitted to twenty-six medical centers (affiliated with Shiraz University of Medical Sciences) from 10 June to 26 December 2020 were reviewed and analyzed. An elastic-net regularized Cox proportional hazards (PH) regression and model approximation via backward elimination were utilized to optimize a predictive model of time to in-hospital death. The model was further reduced to its core features to maximize simplicity and generalizability. Results The empirical in-hospital mortality rate among the re-infected COVID-19 patients was 9.5%. In addition, the mortality rate among the intubated patients was 83.5%. Using the Kaplan-Meier approach, the OS (95% CI) rates for days 7, 14, and 21 were 87.5% (81.6-91.6%), 78.3% (65.0-87.0%), and 52.2% (20.3-76.7%), respectively. The elastic-net Cox PH regression retained 8 out of 35 candidate features of death. Transfer by Emergency Medical Services (EMS) (HR=3.90, 95% CI: 1.63-9.48), SpO2≤85% (HR=8.10, 95% CI: 2.97-22.00), increased serum creatinine (HR=1.85, 95% CI: 1.48-2.30), and increased white blood cells (WBC) count (HR=1.10, 95% CI: 1.03-1.15) were associated with higher in-hospital mortality rates in the re-infected COVID-19 patients. Conclusion The results of the machine-learning analysis demonstrated that transfer by EMS, profound hypoxemia (SpO2≤85%), increased serum creatinine (more than 1.6 mg/dL), and increased WBC count (more than 8.5 (×109 cells/L)) reduced the OS of the re-infected COVID-19 patients. We recommend that future machine-learning studies should further investigate these relationships and the associated factors in these patients for a better prediction of OS.

Objective: To deWne the safety of major hepatectomy for hepatocellular carcinoma (HCC) associated with cirrhosis and the selection criteria for surgery in terms of hospital mortality.Design: Major hepatectomy for HCC in the presence of cirrhosis is considered to be contraindicated by many surgeons because the reported mortality rate is high (26% to 50%). Previous workers recommended that only selected patients with Child's A status or indocyanine green (ICG) retention at 15 minutes of less than 10% undergo major hepatectomy. A survery was made, therefore, of our patients with HCC and cirrhosis undergoing major hepatectomy between 1989 and 1994.Setting: A tertiary referral center.Patients: The preoperative, intraoperative, and post-operative data of 54 patients with cirrhosis who had major hepatectomy were compared with those of 25 patients with underlying chronic active hepatitis and 22 patients with normal livers undergoing major hepatectomy for HCC. The data had been prospectively collected.Intervention: Major hepatectomy, defined as resection of two or more liver segments by Goldsmith and Woodburn nomenclature, was performed on all the patients. Main Outcome Measure: Hospital mortality, which was defined as death within the same hospital admission for the hepatectomy.Results: Preoperative liver function in patients with cirrhosis was worse than in those with normal livers. The intraoperative blood loss was also higher (P=.01), but for patients with cirrhosis, chronic active hepatitis, and normal livers, the hospital mortality rates (13%, 16%, and 14%, respectively) were similar. The hospital mortality rate for patients with cirrhosis in the last 2 years of the study was only 5%. Patients with cirrhosis could tolerate up to 10 L of blood loss and survive the major hepatectomy. By discriminant analysis, an ICG retention of 14% at 15 minutes was cutoff level that could maximally separate the patients with cirrhosis with and without mortality.Conclusion: Major hepatectomy for HCC in the presence of cirrhosis is associated with a mortality rate that is not different from the rate for patients with normal livers. An ICG retention of 14% at 15 minutes would serve as a better selection criterion than the 10% previously used.

Abstract Background: Liver failure in pregnancy is a rare but potentially severe disease with a high rate of short-term morbidity and mortality, while there is still a lack of accurate diagnosis, effective treatments and prognostic indicators for liver failure in pregnancy. This study aims to retrospectively investigate the clinical characteristics of liver failure in pregnancy caused by AFLP and hepatitis B, and to explore the potential prognostic indicators. Methods: Sixty-two pregnant women with symptoms and signs of hepatic dysfunction, admitting to the Third Affiliated Hospital of Sun Yat-sen University between January 1, 2010 and December 31, 2019 were retrospectively recruited. The baseline clinical characteristics, in-hospital mortality and changes of important laboratory examination parameters during hospitalization were determined.Results: The in-hospital mortality rate of liver failure in pregnancy was 27.4% and most of the deaths were recorded in the first 7 days after admission. Patients suffered in-hospital death had a significant lower gestational age, a higher incidence rate of hepatorenal syndrome and were more likely to receive hysterectomy but less likely to receive intrauterine balloon tamponade. The baseline aspartate aminotransferase, total bilirubin, indirect bilirubin and platelet levels were significantly higher, while cholinesterase, prothrombin activity and creatinine levels were significantly lower in patients with in-hospital death than that in patients discharged alive. The change tendencies of total bilirubin level and prothrombin activity were greatly different between patients with in-hospital deaths and patients discharged alive. Some differences in baseline clinical characteristics between different underlying etiologies of pregnant patients with liver failure were also detected.Conclusions: The mortality rate of liver failure in pregnancy is high especially within 7 days after admission. The change tendencies of total bilirubin and prothrombin activity were greatly different between dead and survived patients with liver failure during hospitalization, which suggested that these parameters might be important prognostic factors of liver failure in pregnancy and their alterations should be carefully tracked.

Abstract Background: Both sepsis and AKI are diseases of major concern in intensive care unit (ICU). This study aimed to evaluate the excess mortality attributable to sepsis for acute kidney injury (AKI).Methods: A propensity score-matched analysis of a prospective cohort study about sepsis epidemiology in 18 Chinese ICUs (January 2014-August 2015) was performed (registration number: ChiCTR-ECH-13003934). Propensity score model was sequentially conducted to match AKI patients with and without sepsis on day 1, day 2, and day 3-5. The primary outcome was hospital death of AKI patients. Propensity score-matched analyses were conducted to estimate the excess mortality attributable to sepsis for AKI. Results: A total of 2008 AKI patients (40.9%) were eligible for the study. Of the 1010 AKI patients with sepsis, 619 (61.3%) were matched to 619 AKI patients in whom sepsis did not develop during the screening period of the study. The hospital mortality rate of matched AKI patients with sepsis was 205 of 619 (33.1%) compared with 150 of 619 (24.0%) for their matched AKI controls without sepsis (p = 0.001). The attributable mortality of total sepsis for AKI patients was 9.1% (95% CI 4.8-13.3%). Matched AKI patients with and without sepsis were subgrouped according to the severity of sepsis (sepsis, septic shock). Of the matched patients with sepsis, 328 (53.0%) diagnosed septic shock. The mortality rate showed remarkably higher in matched AKI patients with septic shock (43.9%) than their controls of patients without sepsis (27.7%). The attributable mortality of septic shock for AKI was 16.2% (95% CI 11.3-20.8%, p < 0.001). Further, the attributable mortality of sepsis for AKI was 1.4% (95% CI 4.1-5.9%, p = 0.825), although there was no significant difference of mortality rate observed between matched AKI patients with and without sepsis (21.0% vs. 19.6%).Conclusions: The attributable hospital mortality of total sepsis for AKI were 9.1%. Septic shock contributes to major excess mortality rate for AKI than sepsis.
