Abstract
Reduction of the time required for medical evacuation to the regional vascular center in order to carry out percutaneous coronary intervention in case of ST-segment elevation acute coronary syndrome is an essential factor directly affecting the mortality rate of this condition. The concept of territorial attribution in rendering emergency medical services militates against the effective use of such emergency medical services aimed to promptly deliver patients to the hospital. Research objective. The research objective is to study the efficiency of trans-regional communication in reducing the time required to deliver patients with ST-segment elevation acute coronary syndrome to hospitals in order to carry out percutaneous coronary intervention and its impact on acute myocardial infarction mortality rate basing on the digital twin of Kurgan region. Materials and methods. the digital twin of the Kurgan region represents the time required to evacuate patients with ST-segment elevation acute coronary syndrome to regional vascular centers by ambulance crews in pursuance with an applicable order, compared with patient routing in case of trans-regional cooperation with vascular centers of neighboring regions. Results: due to the implementation of trans-regional cooperation, mean patient evacuation time within the region had been reduced by 21,3 ± 9,84 minutes, and mean time on routes from the localities wherefrom it was faster to deliver patients to vascular centers in neighboring regions had been reduced by 55±25,73 minutes. The estimated myocardial infarction mortality rate on average for the Kurgan region caused by medical evacuation time reduction in case of implementing trans-regional cooperation had been reduced by 5,32%. Conclusions: the use of resources of neighboring regions when working out regional orders on routing the patients with acute coronary syndrome in a number of instances contributes to the provision of two-hour availability of percutaneous coronary intervention and serves as a significant reserve for acute myocardial infarction mortality reduction.
