Impact of Point-of-Care Ultrasound in the Emergency Department on Care Processes and Outcomes in Critically Ill Nontraumatic Patients.

ABSTRACT: Outcomes data on point-of-care ultrasound (POCUS) in critically ill patients are lacking. This study examines the association between POCUS in the emergency department and outcomes in critically ill patients. Design:Retrospective cohort study of critically ill emergency department patients in two academic emergency departments. All emergency department patients admitted to the intensive care unit or that die in the emergency department were entered prospectively into a registry. Setting:Two academic emergency departments. Patients:All adult (> 18 years old) non-trauma patients with hemodynamic instability [shock index (heart rate/systolic blood pressure) > 0.6] between November 1, 2013-October 31, 2016, were included. Interventions:Cohorts were assigned as follows: no POCUS (cohort 1), POCUS prior to a key intervention (cohort 2), and POCUS after a key intervention (cohort 3). A key intervention was either a fluid bolus or vasoactive drug initiation. Measurements and Main Results:Multivariable logistic regression was used to evaluate the association between POCUS use and the primary outcome of in-hospital mortality. We conducted several sensitivity analyses including propensity score matching and inverse-probability-weighted regression-adjustment along with multiple imputation to account for non-random assignment of POCUS as well as bias due to missing data. Of the 7,734 eligible patients, 2,293 patients were excluded. The remaining 5,441 patients were included in the analysis: 4165 in Cohort 1, 614 in Cohort 2, and 662 in Cohort 3. Mortality was 22%, 29%, and 26%, respectively (p < 0.001). POCUS prior to an intervention was associated with an adjusted odds ratio for death of 1.41 (95% CI, 1.12-1.76) compared to no POCUS. The sensitivity analyses showed an absolute increased mortality of +0.05 (95% CI, 0.02-0.09) for cohort 2 compared to 1. Conclusions:POCUS use prior to interventions appears to be associated with care delays and increased in-hospital mortality compared to critically ill patients with no POCUS. Further explorations of the impact of POCUS in the emergency department appear warranted.

Project description:ObjectivesEmergency department boarding is the practice of caring for admitted patients in the emergency department after hospital admission, and boarding has been a growing problem in the United States. Boarding of the critically ill has achieved specific attention because of its association with poor clinical outcomes. Accordingly, the Society of Critical Care Medicine and the American College of Emergency Physicians convened a Task Force to understand the implications of emergency department boarding of the critically ill. The objective of this article is to review the U.S. literature on (1) the frequency of emergency department boarding among the critically ill, (2) the outcomes associated with critical care patient boarding, and (3) local strategies developed to mitigate the impact of emergency department critical care boarding on patient outcomes.Data sources and study selectionReview article.Data extraction and data synthesisEmergency department-based boarding of the critically ill patient is common, but no nationally representative frequency estimates has been reported. Boarding literature is limited by variation in the definitions used for boarding and variation in the facilities studied (boarding ranges from 2% to 88% of ICU admissions). Prolonged boarding in the emergency department has been associated with longer duration of mechanical ventilation, longer ICU and hospital length of stay, and higher mortality. Health systems have developed multiple mitigation strategies to address emergency department boarding of critically ill patients, including emergency department-based interventions, hospital-based interventions, and emergency department-based resuscitation care units.ConclusionsEmergency department boarding of critically ill patients was common and was associated with worse clinical outcomes. Health systems have generated a number of strategies to mitigate these effects. A definition for emergency department boarding is proposed. Future work should establish formal criteria for analysis and benchmarking of emergency department-based boarding overall, with subsequent efforts focused on developing and reporting innovative strategies that improve clinical outcomes of critically ill patients boarded in the emergency department.
