Doctors as Device Manufacturers? Regulation of Clinician-Generated Innovation in the ICU.
Critical care physicians are rich sources of innovation, developing new diagnostic, prognostic, and treatment tools they deploy in clinical practice, including novel software-based tools. Many of these tools are validated and promise to actively help patients, but physicians may be unlikely to distribute, implement, or share them with other centers noncommercially because of unsettled ethical, regulatory, or medicolegal concerns. This Viewpoint explores the potential barriers and risks critical care physicians face in disseminating device-related innovations for noncommercial purposes and proposes a framework for risk-based evaluation to foster clear pathways to safeguard equitable patient access and responsible implementation of clinician-generated technological innovations in critical care.

Evaluation of a Physiologic-Driven Closed-Loop Resuscitation Algorithm in an Animal Model of Hemorrhagic Shock.
Appropriate resuscitation from hemorrhagic shock is critical to restore tissue perfusion and to avoid over-resuscitation. The objective of this study was to test the ability of a closed-loop diagnosis and resuscitation algorithm called resuscitation from shock using functional hemodynamic monitoring using invasive monitoring (ReFit1) and minimally invasive monitoring (ReFit2) to identify, treat, and stabilize a porcine model of severe hemorrhagic shock. ⋯ Our physiologically based functional hemodynamic monitoring-centered closed-loop resuscitation system can effectively diagnose and treat cardiovascular shock due to hemorrhage and air embolism.

High-Density Lipoprotein Anti-Inflammatory Capacity and Acute Kidney Injury After Cardiac and Vascular Surgery: A Prospective Observational Study.
Acute kidney injury (AKI) predicts death after cardiac and vascular surgery. Higher preoperative high-density lipoprotein (HDL) concentrations are associated with less postoperative AKI. In animals, HDL's anti-inflammatory capacity to suppress endothelial cell adhesion molecule expression reduces kidney damage due to ischemia and hemorrhagic shock. The objective of this study is to evaluate the statistical relationship between HDL anti-inflammatory capacity and AKI after major cardiac and vascular surgery. ⋯ Patients with chronic kidney disease undergoing cardiac and vascular surgery who have dysfunctional, pro-inflammatory HDL have a higher risk of postoperative AKI compared with patients with anti-inflammatory HDL. Conversely, a higher HDL anti-inflammatory capacity is associated with a lower risk of postoperative AKI, independent of HDL concentration. Higher long-term statin dose is associated with higher HDL anti-inflammatory capacity.

Survival After Extracorporeal Cardiopulmonary Resuscitation Based on In-Hospital Cardiac Arrest and Cannulation Location: An Analysis of the Extracorporeal Life Support Organization Registry.
Explore whether extracorporeal cardiopulmonary resuscitation (ECPR) mortality differs by in-hospital cardiac arrest location and whether moving patients for cannulation impacts outcome. ⋯ ECPR patients who experienced cardiac arrest in the ICU and in acute care hospital beds had increased odds of mortality compared with other locations. Moving patients for ECPR cannulation was not associated with improved outcomes.

Validating the Fluctuating Mental Status Evaluation in Neurocritically Ill Patients With Acute Stroke.
Neurocritically ill patients are at high risk for developing delirium, which can worsen the long-term outcomes of this vulnerable population. However, existing delirium assessment tools do not account for neurologic deficits that often interfere with conventional testing and are therefore unreliable in neurocritically ill patients. We aimed to determine the accuracy and predictive validity of the Fluctuating Mental Status Evaluation (FMSE), a novel delirium screening tool developed specifically for neurocritically ill patients. ⋯ In this validation study, we found that the FMSE was an accurate delirium screening tool in neurocritically ill stroke patients. FMSE scores greater than or equal to 1 indicate "possible" delirium and should be used when prioritizing sensitivity, whereas scores greater than or equal to 2 indicate "probable" delirium and should be used when prioritizing specificity.
