Preventable causes in the mortality structure of the population of the Republic of Sakha (Yakutia) and its Arctic zone

The aim of the survey was to assess the population mortality from preventable causes in the Sakha Republic (Yakutia) using the Russian classification. It was found that 37.2% of the total number of deaths in the republic in 2020¬–2023 could have been avoided, including 71.8% of the cases by primary prevention measures (Group 1 of the causes); 3.2% – by early diagnosis of diseases (Group 2 of the causes); and 25.0% – by adequate treatment (Group 3 of the causes). In the mortality structure in the Arctic zone of the republic, these causes accounted for 75.1%, 2.6%, and 22.3%, respectively. The greatest contribution to preventable mortality of the population in Yakutia is made by lifestyle-related diseases. Losses due to injuries and poisoning account for 35.7% in the preventable mortality in the republic as a whole and for 45.0% in the Arctic zone of the region. 24.9% of fatal cases in the Arctic zone (10.5% in the republic) directly depended on the quality of medical care. To minimize these losses, it remains important to identify diseases at early stages; to address them with adequate treatment; and, for district hospitals, to refer patients to level 3 medical institutions in a timely manner.
