Aim. Assessment of the impact of independent ultrasound screening by the emergency physician on the daily activities of the emergency department. Methods. The effectiveness of the use of ultrasound screening by the emergency physician was assessed using computer-based simulation modeling and the subsequent implementation of the data obtained into the practical work of the emergency department. The results were analyzed using descriptive statistical methods. Results. In the course of the study, a simulated model of emergency department was built, similar to the actually functioning department in the Pavlov First St. Petersburg State Medical University. The new professional emergency physician’s standard, requiring knowing the basics of ultrasound-based diagnosis, were implemented first in the model and then in everyday practice. Independent ultrasound screening by the emergency physician allows reducing the length of stay of patients in the emergency department and the workload on medical personnel at the same time increasing the capacity of the department which is confirmed both by computer simulation and by actual implementation in the daily activities of the department. Conclusion. The data received are indicative of a positive impact of independent ultrasound screening on the hospital stay of patients in the department and workload on the medical staff; emergency residency program should be complemented by teaching the basics of ultrasound diagnosis.
