Weight as a Risk Factor for Mortality in Critically Ill Patients.

ABSTRACT:

Objectives

To explore the hypothesis that obesity is associated with increased mortality and worse outcomes in children who are critically ill.

Methods

Secondary analysis of the Assessment of Worldwide Acute Kidney Injury, Renal Angina, and Epidemiology study, a prospective, multinational observational study. Patients between 3 months and 25 years across Asia, Australia, Europe, and North America were recruited for 3 consecutive months. Patients were divided into 4 groups (underweight, normal weight, overweight, and obese) on the basis of their BMI percentile for age and sex.

Results

A total of 3719 patients were evaluated, of whom 542 (14%) had a primary diagnosis of sepsis. One thousand fifty-nine patients (29%) were underweight, 1649 (44%) were normal weight, 423 (11%) were overweight, and 588 (16%) were obese. The 28-day mortality rate was 3.6% for the overall cohort and 9.1% for the sepsis subcohort and differed significantly by weight status (5.8%, 3.1%, 2.2%, and 1.8% for subjects with underweight, normal weight, overweight, and obesity, respectively, in the overall cohort [P < .001] and 15.4%, 6.6%, 3.6%, and 4.7% in the sepsis subcohort, respectively [P = .003]). In a fully adjusted model, 28-day mortality risk was 1.8-fold higher in the underweight group versus the normal weight group in the overall cohort and 2.9-fold higher in the sepsis subcohort. Patients who were overweight and obese did not demonstrate increased risk in their respective cohorts. Patients who were underweight had a longer ICU length of stay, increased need for mechanical ventilation support, and a higher frequency of fluid overload.

Conclusions

Patients who are underweight make up a significant proportion of all patients in the PICU, have a higher short-term mortality rate, and have a more complicated ICU course.

Project description:BackgroundThe AbSeS-classification defines specific phenotypes of patients with intra-abdominal infection based on the (1) setting of infection onset (community-acquired, early onset, or late-onset hospital-acquired), (2) presence or absence of either localized or diffuse peritonitis, and (3) severity of disease expression (infection, sepsis, or septic shock). This classification system demonstrated reliable risk stratification in intensive care unit (ICU) patients with intra-abdominal infection. This study aimed to describe the epidemiology of ICU patients with pancreatic infection and assess the relationship between the components of the AbSeS-classification and mortality.MethodsThis was a secondary analysis of an international observational study ("AbSeS") investigating ICU patients with intra-abdominal infection. Only patients with pancreatic infection were included in this analysis (n=165). Mortality was defined as ICU mortality within 28 days of observation for patients discharged earlier from the ICU. Relationships with mortality were assessed using logistic regression analysis and reported as odds ratio (OR) and 95% confidence interval (CI).ResultsThe overall mortality was 35.2% (n=58). The independent risk factors for mortality included older age (OR=1.03, 95% CI: 1.0 to 1.1 P=0.023), localized peritonitis (OR=4.4, 95% CI: 1.4 to 13.9 P=0.011), and persistent signs of inflammation at day 7 (OR=9.5, 95% CI: 3.8 to 23.9, P<0.001) or after the implementation of additional source control interventions within the first week (OR=4.0, 95% CI: 1.3 to 12.2, P=0.013). Gram-negative bacteria were most frequently isolated (n=58, 49.2%) without clinically relevant differences in microbial etiology between survivors and non-survivors.ConclusionsIn pancreatic infection, a challenging source/damage control and ongoing pancreatic inflammation appear to be the strongest contributors to an unfavorable short-term outcome. In this limited series, essentials of the AbSeS-classification, such as the setting of infection onset, diffuse peritonitis, and severity of disease expression, were not associated with an increased mortality risk.ClinicalTrials.gov number: NCT03270345.

Project description:Prior research has indicated that adopting strict glycemic control measures might elevate the risk of hypoglycemia and result in higher mortality rates among critically ill patients. However, there is a lack of studies investigating the incidence of hypoglycemia and its consequential outcomes in real-world clinical settings. This retrospective cohort study was conducted at Taichung Veterans General Hospital, utilizing critical care databases covering the period from 2015 to 2020. The objective was to examine the outcomes and identify risk factors associated with hypoglycemia in critically ill patients. Out of the total of 16,699 patients admitted to the intensive care units (ICUs), 2,115(12.7%) experienced at least one episode of hypoglycemia were included in the analysis. Critically ill patients who developed hypoglycemia had a significantly higher hospital mortality rate compared to those who did not experience hypoglycemia. (48.9% vs. 15.9%, p < 0.001). Moreover, patients with more severe hypoglycemia exhibited a higher mortality rate (moderate hypoglycemia: hazard ratio [HR] 1.477, 95% confidence interval [C.I.] 1.351-1.614, p < 0.001; severe hypoglycemia: HR 1.847, 95% C.I. 1.607-2.123, p < 0.001) compared to those without hypoglycemia. Additionally, patients with greater frequency of hypoglycemic episodes also showed a higher mortality rate (one episode HR 1.504, 95% C.I. 1.366-1.657, p < 0.001; multiple episodes HR 1.613, 95% C.I. 1.444-1.801, p < 0.001) compared to those without hypoglycemia. Patient who experienced spontaneous hypoglycemia (53.9% vs. 42.4%, p < 0.001) and those without a prior diagnosis of diabetes (60.2% vs. 37.0%, p < 0.001) had higher mortality rate. Hypoglycemia frequently occurs and serves as an independent risk factor for mortality among critically ill individuals, particularly in cases of severe and recurrent episodes. Patients experiencing spontaneous hypoglycemia, as well as those lacking a diabetes diagnosis, demonstrated elevated mortality rates.

Project description:BackgroundHospitals are increasingly adopting 24-hour intensivist physician staffing as a strategy to improve intensive care unit (ICU) outcomes. However, the degree to which nighttime intensivists are associated with improvements in the quality of ICU care is unknown.MethodsWe conducted a retrospective cohort study involving ICUs that participated in the Acute Physiology and Chronic Health Evaluation (APACHE) clinical information system from 2009 through 2010, linking a survey of ICU staffing practices with patient-level outcomes data from adult ICU admissions. Multivariate models were used to assess the relationship between nighttime intensivist staffing and in-hospital mortality among ICU patients, with adjustment for daytime intensivist staffing, severity of illness, and case mix. We conducted a confirmatory analysis in a second, population-based cohort of hospitals in Pennsylvania from which less detailed data were available.ResultsThe analysis with the use of the APACHE database included 65,752 patients admitted to 49 ICUs in 25 hospitals. In ICUs with low-intensity daytime staffing, nighttime intensivist staffing was associated with a reduction in risk-adjusted in-hospital mortality (adjusted odds ratio for death, 0.62; P=0.04). Among ICUs with high-intensity daytime staffing, nighttime intensivist staffing conferred no benefit with respect to risk-adjusted in-hospital mortality (odds ratio, 1.08; P=0.78). In the verification cohort, there was a similar relationship among daytime staffing, nighttime staffing, and in-hospital mortality. The interaction between nighttime staffing and daytime staffing was not significant (P=0.18), yet the direction of the findings were similar to those in the APACHE cohort.ConclusionsThe addition of nighttime intensivist staffing to a low-intensity daytime staffing model was associated with reduced mortality. However, a reduction in mortality was not seen in ICUs with high-intensity daytime staffing. (Funded by the National Heart, Lung, and Blood Institute.).
