Abstract
The aim of the study is to analyze the main results of optimization of the work of aviation medical brigades in a metropolis and the dynamics of typical reasons for refusal to use an ambulance helicopter. Materials and research methods. The article presents the characteristics of the BK-117C-2 (EC-145) helicopter used to deliver patients to a specialized medical organization. A retrospective analysis of all aviation medical brigades flights of the Scientific and Practical Center for Emergency Medical Aid of the Moscow Department of Health in 2017–2019, as well as a comparative analysis of aviation medical brigades performance indicators for 2005–2007 and 2017–2019, was carried out. The main compared indicators: time from the call to the departure of an ambulance helicopter to a patient; time of aviation medical brigade arrival to the place of call; total time before the patient is admitted to a specialized hospital; typical reasons for a refusal to use a helicopter when there is a call for it. Research results and their analysis. The analysis of the research results led to the following conclusions: use of helicopters to provide emergency medical care and to carry out air ambulance evacuation of patients in a metropolis makes it possible to successfully solve a number of complex problems. With the start of optimization and the introduction of algorithms for the operation of ambulance helicopters, flight time to a patient decreased by 2019, compared to 2007, by 1.9 times – from (33.2±1.07) to (17.8±0, 72) min; when evaluating the results of optimizing the aviation medical brigades work in Moscow, it should be borne in mind that there are objective limitations when using an ambulance helicopter. If you do not take into account reasons such as a patient’s refusal or a lack of indications for helicopter evacuation, impossibility of using an ambulance helicopter in the metropolis was on average: in 2017–2019 – 6.51% (210 cases per 3227 applications); in 2005-2007 – 10.23%. For about 10 years, impossibility of evacuating a patient to a specialized hospital has decreased for objective reasons by 3.72%, which emphasizes the effectiveness of the developed algorithms for air ambulance evacuation of urgent patients in a metropolis.
