The use and duration of preintubation respiratory support is associated with increased mortality in immunocompromised children with acute respiratory failure.
The purpose of this retrospective cohort study was to examine the relationship between preintubation respiratory support and outcomes in pediatric patients with acute respiratory failure and to evaluate the impact of immunocompromised (IC) diagnoses on outcomes. The study utilized data from the Virtual Pediatric Systems database which included 82 centers, and focused on patients intubated in the Pediatric Intensive Care Unit (PICU) ranging in age from 1 month old to 17 years of age who received invasive mechanical ventilation (IMV) for more than or equal to 24 hours. Of the 5,348 PICU intubations across 82 centers, high-flow nasal cannula (HFNC) or noninvasive positive-pressure ventilation (NIPPV) or both were used before intubation in 34% (1,825) of patients. Fifty percent of the patients had no IC diagnosis. The researchers found that exposure to HFNC was associated with greater odds of PICU mortality when compared with patients intubated without prior support. When analyzing subgroups of IC status, preintubation support was related to higher odds of PICU mortality in IC patients and HCT patients when compared with IC/ HCT patients intubated without prior respiratory support. A duration of HFNC/NIPPV of more than 6 hours was associated with increased mortality in IC HCT patients. Rates of preintubation HFNC/NIPPV use and PICU mortality varied between the 82 centers. The researchers concluded that greater duration of exposure to HFNC/NIPPV prior to IMV is associated with increased mortality in HCT patients, and preintubation exposure to HFNC and/or NIPPV in IC pediatric patients is associated with increased odds of PICU mortality, independent of the severity of the illness.

Characteristics, outcomes, and trends of patients with COVID-19-related critical illness at a learning health system in the United States.
This study’s objective is to describe the epidemiology of COVID-19-related critical illness, including trends in outcomes and care delivery, using five hospitals within the University of Pennsylvania Health System as a setting. Findings showed that, among patients with COVID-19-related critical illness admitted to ICUs of a learning health system in the United States, mortality seemed to decrease over time despite stable patient characteristics. Recommendations included further studies to confirm this result and to investigate causal mechanisms.

The impact of high-flow nasal cannula use on patient mortality and the availability of mechanical ventilators in COVID-19.
This study looked at the effects of the use of high-flow nasal cannula for COVID-19 patients on mortality and the availability of mechanical ventilators. The authors constructed dynamical simulation models of high-flow nasal cannula and mechanical ventilation use in the United States. There were two outcomes looked for: 1) cumulative number of deaths; and 2) days without available ventilators. The strategy resulted in an estimated number of 10,000-40,000 fewer deaths than if high-flow nasal cannula were not available. This strategy also led up to 25 fewer days without available ventilators.

Evaluating the cost-effectiveness of the ABCDE bundle: impact of bundle adherence on inpatient and 1-year mortality and costs of care.
This study examined the cost-effectiveness of the Awakening and Breathing Coordination, Delirium monitoring/management, and Early exercise/mobility (ABCDE) bundle intervention to improve short- and long-term clinical outcomes for patients requiring ICU care. A 2-year, prospective, cost-effectiveness study in 12 adult ICUs in six hospitals belonging to a large, integrated healthcare delivery system was conducted. Hospitals in the study included a large, urban center and five community hospitals. ICU types included medical/surgical, trauma, neurologic, and cardiac care units. The cohort included 2,953 adults with an ICU stay greater than 24 hours who were on a ventilator for more than 24 hours and less than 14 days. ICUs with high ABCDE bundle adherence significantly decreased odds of inpatient mortality and had significantly higher costs of inpatient care. The incremental cost-effectiveness ratio of high bundle adherence was $15,077 per life saved, and $1,057 per life-year saved.

Utilization of intensive care unit nutrition consultation is associated with reduced mortality.
The aim of this project was to investigate the prevalence of nutrition consultation (NC) in U.S. intensive care units (ICUs) and to examine its association with patient outcomes. Data from the Healthcare Cost and Utilization Project's state inpatient databases was utilized from 2010 - 2014. A multilevel logistic regression model was used to evaluate the relationship between NC and clinical outcomes. The investigators concluded that rates of NC were low in critically ill patients.

Hospital mortality and functional outcomes in pediatric neurocritical care.
Pediatric neurocritical care (PNCC) outcomes research is scarce. In this study, the investigators aimed to expand knowledge about outcomes in PNCC by evaluating death and changes in Functional Status Scale (FSS) from baseline among PNCC diagnoses. The investigators concluded that PNCC patients had high rates of death and new disability at discharge, varying significantly between PNCC diagnoses. Multiple domains of disability were affected, underscoring the ongoing multidisciplinary health care needs of survivors.

Procalcitonin-guided antibiotic discontinuation and mortality in critically ill adults: a systematic review and meta-analysis.
This study is a systematic review and meta-analysis on survival outcomes of using procalcitonin (PCT)-guided antibiotic discontinuation on critically ill adults. The study quality was assessing with the Cochrane risk of bias tool, and GRADEpro was used to grade evidence. PCT-guided discontinuation was associated with decreased mortality, but there was a high risk of bias in many of the studies reviewed with a low certainty of evidence. The authors suggest properly designed studies with mortality as the primary outcome is needed to further answer this question.

Readmission and late mortality after critical illness in childhood.
Researchers sought to understand risks for hospital readmission and trends in mortality during the year following ICU discharge. They found that, in multivariate analysis, risk of nonelective readmission for children without cancer was higher with longer index ICU admission length of stay, younger age, and several chronic and acute conditions. Mortality in the year after ICU discharge was low overall.

Outcomes of patients discharged to skilled nursing facilities after acute care hospitalizations.
This study evaluated previously independent older patients discharged to skilled nursing facilities (SNFs) and identified risk factors for failure to return home and death and development of a predictive tool to determine likelihood of adverse outcome. It found that a large proportion of older patients discharging to SNFs never return home.

Mortality among older adults before versus after hospital transition to intensivist staffing.
The researchers sought to determine whether hospitals can reduce their mortality by adopting an intensivist staffing model. Adoption of an intensivist staffing model was not associated with improved mortality in Medicare beneficiaries. These findings suggest that the lower mortality rates previously observed at hospitals with intensivist staffing may be attributable to other factors.

Coefficient of glucose variation is independently associated with mortality in critically ill patients receiving intravenous insulin.
The researchers studied the association between coefficient of variation of glucose and mortality and also whether the association between glycemic variability and mortality was independent of hypoglycemia and other patient attributes. They found that blood glucose coefficient of variation was associated with 30-day mortality both in diabetic as well as in non-diabetic patients. The association was independent of hypoglycemia, blood glucose target, age, disease severity, and comorbidities.

Mortality among patients admitted to strained intensive care units.
A study of 264,401 patients admitted to 155 U.S. intensive care units (ICUs) found several factors associated with small increases in mortality: ICU census on the day of a patient’s admission, the presence of higher acuity patients, and the proportion of new admissions. These sources of ICU strain were associated with mortality increases particularly in ICUs employing closed staffing models.
