Mediators of the Impact of Hourly Net Ultrafiltration Rate on Mortality in Critically Ill Patients Receiving Continuous Renal Replacement Therapy.
During continuous renal replacement therapy, a high net ultrafiltration rate has been associated with increased mortality. However, it is unknown what might mediate its putative effect on mortality. In this study, we investigated whether the relationship between early (first 48 hr) net ultrafiltration and mortality is mediated by fluid balance, hemodynamic instability, or low potassium or phosphate blood levels using mediation analysis and the primary outcome was hospital mortality. ⋯ An early net ultrafiltration greater than 1.75 mL/kg/hr was independently associated with increased hospital mortality. Its putative effect on mortality was direct and not mediated by a causal pathway that included fluid balance, low blood pressure, vasopressor use, hypokalemia, or hypophosphatemia.

ReviewA Guide to Performance Evaluation for the Intensivist: Ongoing Professional Practice Evaluation and Focused Professional Practice Evaluation in the ICU.
In 2008, The Joint Commission implemented a new standard mandating a detailed evaluation of a provider's performance. The Ongoing Professional Practice Evaluation was designed to provide ongoing performance evaluation as opposed to periodic evaluation. The Focused Professional Practice Evaluation was designed to evaluate the performance of providers new to the medical staff or providers who are requesting new privileges. To date, we are unable to find critical care specific literature on the implementation of Ongoing Professional Practice Evaluation/Focused Professional Practice Evaluation. The purpose of this concise definitive review is to familiarize the reader with The Joint Commission standards and their application to Ongoing Professional Practice Evaluation/Focused Professional Practice Evaluation design and implementation, literature review in the noncritical care setting, and future process optimization and automation. ⋯ Currently, there is no standard process to develop Ongoing Professional Practice Evaluation and Focused Professional Practice Evaluation processes in critical care medicine. Departments and institutions can tailor metrics and processes but it might be useful to standardize some metrics to assure the overall quality of care. In the future utilization of newer technologies like applications might make this process less time-intensive.

Multicenter StudyCoronavirus Disease 2019 Pandemic Measures: Reports From a National Survey of 9,120 ICU Clinicians.
Recent reports identify that among hospitalized coronavirus disease 2019 patients, 30% require ICU care. Understanding ICU resource needs remains an essential component of meeting current and projected needs of critically ill coronavirus disease 2019 patients. ⋯ This national ICU clinician survey identifies continued concerns regarding personal protective equipment supplies with the chief issue being N95 respirator availability. As the pandemic continues, ICU clinicians anticipate a number of limited resources that may impact ICU care including personnel, capacity, and surge potential, as well as staff and subsequent family members exposure to severe acute respiratory syndrome coronavirus 2. These persistent concerns greatly magnify personal stress, offering a therapeutic target for professional organization and facility intervention efforts.

Observational StudyFull Finger Reperfusion Time Measured by Pulse Oximeter Waveform Analysis in Children.
Capillary refill time is a noninvasive method to assess tissue perfusion to determine shock status. Capillary refill time is defined as the time required to regain skin color after blanching pressure is applied. Although common methods to measure capillary refill time depend on clinicians' visual assessment, a new approach using a pulse oximeter waveform analysis exists, referred to as full finger reperfusion time. We aim to evaluate reproducibility and validity of the novel full finger reperfusion time measurement using clinicians' visual capillary refill time assessment as a reference standard. ⋯ Full finger reperfusion time demonstrated good reproducibility. Full finger reperfusion time showed moderate correlation with clinician capillary refill time. Full finger reperfusion time was 1.14 seconds longer than capillary refill time. Future studies should focus on the clinical value of full finger reperfusion time as a monitoring device for hemodynamics in critically ill children.
