Observational StudyEvaluation of Organ Dysfunction Scores for Allocation of Scarce Resources in Critically Ill Children and Adults During a Healthcare Crisis.
When healthcare systems are overwhelmed, accurate assessments of patients' predicted mortality risks are needed to ensure effective allocation of scarce resources. Organ dysfunction scores can serve this essential role, but their evaluation in this context has been limited so far. In this study, we sought to assess the performance of three organ dysfunction scores in both critically ill adults and children at clinically relevant mortality thresholds and timeframes for resource allocation and compare it with two published prioritization schemas. ⋯ In the largest analysis of organ dysfunction scores in a general population of critically ill adults and children to date, we found that both the Sequential Organ Failure Assessment and Pediatric Sequential Organ Failure Assessment scores had adequate performance across relevant mortality thresholds and timeframes for resource allocation. Published prioritization schemas that include both pediatric and adult patients may put children at a disadvantage. Furthermore, the distribution of patient and mortality risk in the published schemas may not adequately stratify patients for some high-stakes allocation decisions. This information may be useful to bioethicists, healthcare leaders, and policy makers who are developing resource allocation policies for critically ill patients.

Stability of Do-Not-Resuscitate Orders in Hospitalized Adults: A Population-Based Cohort Study.
Prior work has shown substantial between-hospital variation in do-not-resuscitate orders, but stability of do-not-resuscitate preferences between hospitalizations and the institutional influence on do-not-resuscitate reversals are unclear. We determined the extent of do-not-resuscitate reversals between hospitalizations and the association of the readmission hospital with do-not-resuscitate reversal. ⋯ Do-not-resuscitate reversals at the time of readmission are more common than previously reported. Although changes in patient preferences may partially explain between-hospital differences, we observed a strong hospital effect contributing to high do-not-resuscitate-reversal rates with significant implications for patient outcomes and resource.

Early Percutaneous Tracheostomy in Coronavirus Disease 2019: Association With Hospital Mortality and Factors Associated With Removal of Tracheostomy Tube at ICU Discharge. A Cohort Study on 121 Patients.
Early tracheotomy, defined as a procedure performed within 10 days from intubation, is associated with more ventilator free days, shorter ICU stay, and lower mortality than late tracheotomy. During the coronavirus disease 2019 pandemic, it was especially important to save operating room resources and to have a shorter ICU stay for patients, when ICUs had insufficient beds. In this context of limited resources, early percutaneous tracheostomy could be an effective way to manage mechanically ventilated patients. Nevertheless, current recommendations suggest delaying or avoiding the tracheotomy in coronavirus disease 2019 patients. Aim of the study was to analyze the hospital mortality of coronavirus disease 2019 patients who had received early percutaneous tracheostomy and factors associated with removal of tracheostomy cannula at ICU discharge. ⋯ Early percutaneous tracheostomy was safe and effective in coronavirus disease 2019 patients, giving a good chance of survival and of weaning from tracheostomy cannula at ICU discharge.

The Association of Platelet Decrease Following Continuous Renal Replacement Therapy Initiation and Increased Rates of Secondary Infections.
Thrombocytopenia is common in critically ill patients treated with continuous renal replacement therapy and decreases in platelets following continuous renal replacement therapy initiation have been associated with increased mortality. Platelets play a role in innate and adaptive immunity, making it plausible that decreases in platelets following continuous renal replacement therapy initiation predispose patients to development of infection. Our objective was to determine if greater decreases in platelets following continuous renal replacement therapy correlate with increased rates of secondary infection. ⋯ Platelet count drop by greater than 40% following continuous renal replacement therapy initiation is associated with an increased risk of secondary infection, particularly in patients with thrombocytopenia at the time of continuous renal replacement therapy initiation. Further research is needed to evaluate the impact of both continuous renal replacement therapy and platelet loss on subsequent infection risk.

The first 70 years of critical care can be considered a period of "industrial revolution-like" advancement in terms of progressing the understanding and care of critical illness. Unfortunately, like the industrial revolution's impact on the environment, advancing ICU care of increasingly elderly, immunosuppressed, and debilitated individuals has resulted in a greater overall burden and complexity of nosocomial infections within modern ICUs. Given the rapid evolution of nosocomial infections, the authors provide an updated review. ⋯ Nosocomial infections are an important determinant of outcome for patients in the ICU setting. Systematic research aimed at improving the prevention and treatment of nosocomial infections is still needed.
