Since the emergence of Corona Virus Disease 2019 (COVID-19) in Wuhan city, Hubei Province, China, it has caused thousands of deaths. As the ongoing outbreak of COVID-19 around the world, the number of deaths will definitely continue to increase. We aimed to further describe the clinical characteristics of dead cases with COVID-19 through a large sample and multi-centered study and to find some clinical predictors for the deterioration of COVID-19 during the process. Methods One hundred and seven patients (16 patients from Lei Shen-Shan Hospital, 54 patients from Seventh Hospital of Wuhan and 37 patients from Zhongnan Hospital of Wuhan University) with COVID-19 were enrolled in our research from Jan 22 to Feb 29, 2020. The demographic, clinical, radiological, laboratory and treatment data of all cases were analysed. Results Of the 107 dead patients with COVID-19, 71 (66.4%) were male and 36 (33.6%) were female. The mean age of the patients was 71.2 ± 12.1 years. 82 (76.6%) of patients had chronic diseases. The mean duration from admission to death was 9 (IQR,5-14) days. Respiratory functional damage was the most common one followed by heart and kidney. Hematuria was found in 36(33.6%) patients. 89(83.2%) patients’ albumin levels were decreased. 68(63.6%) patients had anemia. concerning laboratory results, 55 (69.6%) and 56 (70.1%) patients have the elevated white blood cells and elevated Neutrophils during the process;only 43 (54.4%) have the decreased Lymphocytes;The values of platelets and haemoglobin decreased in 64(81.0%) and 58 (73.4%) patients. Alanine aminotransferase and aspartate aminotransferase elevated in near half of patients, while almost 80% of patients have the decreased albumin. The elevated blood urea nitrogen and cystatin C were manifested in about 70% of patients. Procalcitonin was elevated in 38 (71.7%) patients. Conclusions In conclusion, the older men with chronic diseases are more likely to die from COVID-19. Apart from that, more attention should be pay on timely treatment, coinfections, malnutrition, and dysfunction of kidney and coagulation. The rising values (white blood cell, blood urea nitrogen, cystatin C, PCT and PT) and the decreased values (PLT, Hb and albumin) maybe meaningful for predict the poor prognosis.
