Experience with a mobile CT scanner as part of an airmobile hospital of the Ministry of Emergencies of Russia in the field conditions of the Far North to combat the outbreak of a new coronavirus infection.

Background. Large-scale construction of industrial and transport facilities is underway in the Far North of Russia. The process involves more than 10,000 shift workers, and there was a Covid19 outbreak in this population. In order to contain the outbreak and prevent the spread of infection in this area the Russian Emergencies Ministry deployed an airmobile hospital. Purpose. The purpose is to present an experience of work with the mobile CT scanner as part of an airmobile field hospital deployed in the Far North of Russia to combat the Covid-19 outbreak. Materials and methods. On April 6, 2020, the construction site reported a "zero patient" who sought medical aid;the PCR test showed positive results of coronavirus. In the first half of April, over 300 rotation employees applied for medical care, most of them had a positive PCR test. On April 11, a state of emergency was declared in the construction site and, on April 17, 2020, airmobile hospital started operations. Its mission lasted 54 days. The mobile CT scanner (Brightspeed Elite Mobile, GE) was transported by land. The field hospital closely cooperated with the nearest medical institutions and the regional clinical hospital. Results. During its work the airmobile hospital examined 1,678 rotational workers and 408 employees of the Ministry of Emergency Situations of the Murmansk region, with 2,086 CT scans performed. The average age of the patients was 37.8 years, men predominated. In 91.2% of patients, fever was the first symptom of the disease. Blood saturation results ranged from 92% to 99%. The degree of lung involvement ranged from CT 0 to CT 4. During the work of the airmobile hospital, COVID-19 was diagnosed in 500 people, including 328 cases of mild form, 98 - moderate, 74 - severe, no mortalities. Conclusion. A positive experience of application of the mobile CT scanner as part of the AMH field hospital in unfavorable epidemiological conditions of the Far North of the Russian Federation was obtained. CT plays a key role in early detection of infection, differential diagnosis, and identification of complications. Determination of the severity of the disease based on CT data is crucial for patient routing.Copyright © 2021 Medical Visualization. All rights reserved.

Possibilities of computer simulation in optimizing the work of the inpatient emergency department in emergency situations

Relevance. The development of computer technology in recent years is increasingly being introduced into the medical field. Modern programs make it possible to perform imitation modeling of a medical unit in the mode of daily activities and in emergency situations, allow predicting the required number of personnel and bed capacity. Intention. To study the possibilities of computer simulation to optimize the work of an inpatient emergency department in emergency conditions. Methodology. With the help of software, a simulation model of a real inpatient emergency department was developed, experiments were carried out with the formation of emergency situations, the results were compared with data obtained in practice. Results and Discussion. Upon admission of 50 patients per hour, the optimal solution was the conversion of 5 beds of the dynamic observation ward into intensive care beds and the placement of 10 additional beds in the waiting room, as well as the allocation of additional personnel in case of an emergency: 8 doctors, 6 nurses and 2 paramedics, 4 medical registrars. In the experiment of work in the conditions of the first wave of the COVID-19 pandemic, the capacity of the department was sufficient to admit 164 patients in 24 hours, the duration of their stay in the department was (110.0 ± 4.6) minutes. The second wave demonstrated the need to apply simulation modeling as a whole for the entire medical institution, and not just for individual structural units. Conclusion. Planning the work of an inpatient emergency department in an emergency requires preparedness for massive admission of patients. In this case, it is advisable to solve tactical issues in advance, using modern technologies, such as computer simulation. © 2022 Proceedings of the National Academy of Sciences of Belarus.

SIMULATION MODELING AND PRACTICE OF INPATIENT EMERGENCY DEPARTMENT IN COVID-19 PANDEMIC

The article presents the experience of using simulation modeling to optimize inpatient emergency department as an admission unit of a hospital — Center for treatment of patients with new coronavirus infection COVID-19. It was noted that the inpatient emergency department effectively performed the functions of the inpatient department of the Center for treatment of patients with new COVID-19 coronavirus infection for a total of more than 7 months. A correct calculation of staffing and a competent use of the department "zones" ensured efficient and rapid reception of patients during both "waves" of the pandemic. The model also proved positive role of such departments with a large number of patients in a multimillion metropolis needed to be hospitalized on a daily basis. © Burnasyan FMBC FMBA.
