Study characteristics

China

Retrospective cohort study

Medical records

1590

1590 hospitalized COVID-19 patients

The median age of fatal cease was 69 years (range: 51-86 years). Thirty of them were male. The diagnosis of COVID-19 was made based on the World Health Organization interim guidance.7 The diagnosis was confirmed by a positive result of real-time reverse transcriptase-polymerase chain reaction assay or high-throughput sequencing findings from nasal or pharyngeal swab specimens. By the cutoff time of January 31, 2020, a total of 2,007 cases diagnosed with laboratory-confirmed COVID-19 were collected, and 417 cases were excluded because of incomplete medical records.

Multivariate Cox regression analysis - Risk was adjusted for Age, coronary heart disease, cerebrovascular disease, dyspnea, procalcitonin [>0.5ng/mL vs. <=0.5ng/mL], aspartate aminotransferase [>40U/L vs. <=40U/L], total bilirubin [>=17.1umol/L vs. <17.1umol/L] and creatinine [>=133umol/L vs. <133umol/L].


Other information

This study provided the evidence that advanced age, dyspnea, coronary heart disease, cerebrovascular disease, elevated PCT and AST are independent risk factors associated with fatal outcome. The nomogram proposed in this study objectively predicted the prognosis of patients with COVID-19. Earlier identification, more intensive surveillance and appropriate therapy should be considered in these patients with high risk.
