Diseases of the circulatory system, mine-explosive injuries of the chest with direct involvement of the heart and main vessels are life-threatening conditions. Statistics of combat losses during military conflicts show that 1/3 of servicemen with gunshot wounds or chest trauma die due to bleeding and cardiac arrest. With the resolution of the war in the russian federation, the need to provide highly qualified cardiosurgical care will increase. Therefore, a clear understanding of the planning of bed spaces with the calculation of bed days is necessary to ensure the provision of cardiac surgical care. The purpose of the study is to determine the need for the number of bed-places and bed-days during the stay of a sick/ wounded serviceman in a cardiosurgical hospital. The need for bed-days and the number of bed-places was studied, and a conclusion was made about the need to increase them. The amount of inpatient care provided, as well as the duration of treatment of servicemen during a local military conflict (anti-terrorist operation/joint forces operation) in the conditions of stay in a cardiac surgical hospital and compared with the amount of medical care and the duration of treatment of servicemen during martial law were analyzed. As a result of the study, a conclusion was made about the need to organize separate structural divisions for the provision of highly specialized medical care, which includes cardiovascular surgery. It was established that the need for the number of beds during a full-scale war exceeds the planned by 266.3%, and the number of bed days during the stay of a sick/wounded serviceman in a cardiac surgical hospital during martial law increased by 6.3%. Ensuring an adequate need for the number of inpatient places and a justified duration of treatment allows timely provision of quality treatment of the sick and/or wounded, providing them with timely rehabilitation and returning the serviceman to the ranks of the armed forces of Ukraine.\u0000\u0000Keywords: inpatient care, diseases of the circulatory system, cardiovascular surgery, organizational measures, provision of adequate needs, hospitalization of patients and victims.","PeriodicalId":38819,"journal":{"name":"Tokai Journal of Experimental and Clinical Medicine","volume":"10 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90045995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
