Sex and acute oesophageal variceal bleeding-related in-hospital mortality: a 15-year retrospective study

Patient sex and outcomes in children with life-threatening hemorrhage

BACKGROUND

Recent data suggest female sex imparts a survival benefit after trauma in adults. The independent associations between patient sex and age with outcomes have not been examined in children with life-threatening hemorrhage (LTH) from all etiologies.

STUDY DESIGN AND METHODS

In a secondary analysis of a multicenter prospective observational study of children with LTH, Massive Transfusion in Children (MATIC), we analyzed if patient sex and age were associated with differences in severity of illness, therapies, and outcomes. Primary outcomes were 24 hour mortality and weight-adjusted transfusion volume during LTH. Kruskal-Wallis, chi-square testing, and multivariable linear regression were used for adjusted analyses.

RESULTS

Of 449 children, 45% were females and 55% were males. Females were more commonly younger, white, and with less trauma as the etiology of LTH compared to males. Markers of clinical severity were similar between groups, except injury severity score (ISS) was higher in females in the trauma subgroup. In terms of resuscitative practices, females received greater weight-adjusted total transfusion volumes compared to males (76 (40-150) mL/kg vs. 53 (24-100) mL/kg), as well as increased red blood cells (RBCs), plasma, and platelets compared to males. After adjustment for confounders, female sex and age 0-11 years were independently associated with increased transfusion volume during LTH. There were no differences in mortality or adverse outcomes according to patient sex.

CONCLUSION

Patient sex and age may impact factors associated with LTH and therapies received. Studies in developmental hemostasis are needed to determine the optimal transfusion strategy for LTH according to patient sex and age.

Validation and Comparison of a Modified Elixhauser Index for Predicting In-Hospital Mortality in Italian Internal Medicine Wards

Purpose

Burden of comorbidities appears to be related to clinical outcomes in hospitalized patients. Clinical stratification of admitted patients could be obtained calculating a comorbidity score, which represents the simplest way to identify the severity of patients' clinical conditions and a practical approach to assess prevalent comorbidities. Our aim was to validate a modified Elixhauser score for predicting in-hospital mortality (IHM) in internal medicine admissions and to compare it with a different one derived from clinical data previously used in a similar setting, having a good prognostic accuracy.

Patients and Methods

A single-center retrospective study enrolled all patients admitted to internal medicine department between January and June 2016. A modified Elixhauser score was calculated from chart review and administrative data; moreover, a second prognostic index was calculated from chart review only. Comorbidity scores were compared using c-statistic.

Results

We analyzed 1614 individuals without selecting the reason for admission, 224 (13.9%) died during hospital stay. Deceased subjects were older (83.3±9.1 vs 78.4±13.5 years; p<0.001) and had higher burden of comorbidities. The modified Elixhauser score calculated by administrative data and by chart review and the comparator one was 18.13±9.36 vs 24.43±11.27 vs 7.63±3.3, respectively, and the c-statistic was 0.758 (95% CI 0.727-0.790), 0.811 (95% CI 0.782-0.840) and 0.740 (95% CI 0.709-0.771), respectively.

Conclusion

The new modified Elixhauser score showed a similar performance to a previous clinical prognostic index when it was calculated using administrative data; however, its performance improved if calculation was based on chart review.

Effect of gender on mortality and causes of death in cirrhotic patients with gastroesophageal varices. A retrospective study in Norway

Background & aims

The prognostic role of gender in patients with liver cirrhosis is not fully understood. Our primary aim was to assess how gender affects cumulative incidence and risk of death without liver transplantation (LT) in cirrhotic patients with gastroesophageal varices. Secondary aims were to assess the relationship between gender and cause specific death, risk of variceal bleeding and incidence rates of gastroesophageal varices in patients with cirrhosis.

Methods

All new patients with gastroesophageal varices due to liver cirrhosis at Oslo University Hospital between 2006 and May 2016 were identified. Clinical data were retrieved retrospectively from hospital files. Causes of death were classified according to a specified protocol in cases of in-hospital-death, otherwise by data from the Norwegian Death Registry. Competing risk analyses were used to calculate cumulative incidences and risks of i) all-cause death, ii) cause-specific death and iii) variceal bleeding or re-bleeding.

Results

Cumulative one- and five years incidence of death without LT in 266 included patients were 28% and 51%, respectively. In univariate analysis, risk of death was positively associated with age, Child Pugh class, alcoholic liver disease and presentation with variceal bleeding, and negatively associated with female sex. In a multivariate model, risk of death without LT was associated with female sex (SHR 0.59 [0.40–0.86]), age (SHR 1.05 [1.04–1.07] per year), Child Pugh class B (SHR 1.54 [1.03–2.32]) and Child Pugh class C (SHR 4.29 [2.57–7.17]). Variceal bleeding caused 27% of deaths. Adjusting for age and Child Pugh score, a trend towards reduced risk of death due to variceal bleeding was seen in women (SHR 0.53; [0.26–1.06]). High alcohol consumption was associated with increased risk of first variceal bleeding, both at univariate analysis (SHR 7.73 [1.71–34.9]) and multivariate analysis (SHR 13.9 [2.51–77.0]).

Conclusions

Reduced mortality due to variceal bleeding may contribute to improved survival without LT in cirrhotic women with gastroesophageal varices.
