Does Emergency Department Measured Cardiac Output Predict Organ Failure at 48 Hours? A Pilot Study

Published on: 2018-01-29


Background: Cardiac performance is predictive of mortality in a wide range of conditions. We set out to study whether cardiac index predicts outcome in emergency department (ED) patients.

Methods: We performed a prospective observational study using a convenience sample of 58 patients presenting to the resuscitation area of an inner-city teaching hospital over 4 months. We measured cardiac index on initial presentation using an Ultrasonic Cardiac Output Monitor (USCOM™). We looked primarily at whether cardiac index predicts organ failure at 48 hours.

Results: Cardiac index was shown to be predictive of organ failure at 48 hours with an OR 4.71 95% CI 1.12 to 19.70 p=0.03.

Conclusions: This pilot data found that cardiac index measured using USCOM™ predicts 48-hour organ failure. However, the study is limited in its conclusions by having only 58 full participants available for analysis.
