Emergency ultrasound services as perceived by directors of radiology and emergency departments

Despite widespread concern that emergency ultrasound services are not widely available after regular business hours, data supporting or refuting this concern have not been reported. To determine the availability of emergency ultrasound services as perceived by directors of emergency departments (EDs) and radiology departments, direct mail survey was sent to both ED Directors and Directors of Radiology at 100 large teaching hospitals (more than 300 beds) and 100 smaller nonteaching hospitals (fewer than 300 beds) chosen at random from the American Heart Association Guide. Questions elicited the directorsʹ perceptions of availability of emergency ultrasound services in their own institutions as well as their attitudes toward performance of ultrasound examinations by emergency physicians. The overall response rate was 53%. It was found that 24-hour in-house ultrasound services are rarely available even in large teaching hospitals, even as reported by Directors of Radiology. ED Directors and Directors of Radiology differ significantly in perceptions of ultrasound availability, clinical importance of emergency ultrasound, and desirability of ultrasound performance by ED physicians.
