Reduction of Inhospital Mortality of Patient Admissions to Cardiac Intensive Care Units During the COVID-19 Pandemic in Hunan, China

摘要

This study aims to evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on patient admissions to Hunan's cardiac intensive care units (CCUs). We conducted a retrospective, single-center study. Data were collected from patients who were confirmed to have critical cardiovascular disease and admitted to the CCU of the Second Xiangya Hospital of Central South University, Hunan, from January 23 to April 23, 2020. Compared with the same period in 2019, the results show that the number of hospitalization decreased by 19.6%; the inhospital mortality rate of CCU was decreased (28.57% versus 16.67%; odds ratio (OR), 0.50; 95% confidence interval (CI), 0.251-0.996; P = 0.047); hospital stay was decreased (7.97 versus 12.36, P 0.001); hospital emergency percutaneous coronary intervention (PCI) rate in patients with acute coronary syndromes (ACS) significantly decreased (76.00% versus 39.00%, P 0.001); among this, the PCI rate of patients with ST-segment elevation myocardial infarction (STEMI) decreased (76.32% versus 55.17%, P = 0.028) as well. In addition, the number of patients transferred from other hospitals significantly decreased (76.79% versus 56.67%, P = 0.002), and the number of patients transferred from other cities also decreased by 10.75%. During the outbreak of the COVID-19 epidemic in Hunan Province, the number of patients admitted to CCU decreased, as well as the mortality rate; fewer patients with severe cardiovascular disease can be transported to better hospitals from remote rural areas. In addition to epidemic prevention and control, experts in China should focus on improved emergency transport medical services to reduce this impact.
