新冠肺炎患者死亡时间的分析.

Objective To investigate the death time of patients with coronavirus disease 2019 (COVID-19). Methods The death time was calculated and analyzed using individual data and aggregated data through the daily notification of the epidemic situation and the death cases published on the website of the Heath Commission of China and provinces. Results In the 153 patients who died of COVID-19. the shortest time from onset to death was 4 days and the longest time was 50 days with the mean± standard deviation of (16.7±9.2) days. The median was 14 days and the 95 % confidence interval was 4.6-42.9. The shortest time from admission to death was 1 day and the longest time was 50 days with the mean ± standard deviation of 02.1±7.81 days. The median was 11 days and the 95% confidence interval was 2-32.8. The time curve from diagnosis to death was skewed. The death time from diagnosis to death was 0 to 48 days with the mean ± standard deviation of (11.1±8.9) days. The median was 9 days. the interquartile interval was 10.5 days, and the 95% confidence interval was 0-35.4. It took 3 days from onset to admission and 1 day from admission to diagnosis. Aggregated data showed tha t the time from diagnosis to death of COVID-19 patients in China. China (except Hubei Province), Hubei Province and Wuhan City was 8.9, 6 and 6 days. respectively. Conclusion The time from diagnosis to death of COVID-19 patients varied significantly. with the median time of 6-9 days in different regions. [ABSTRACT FROM AUTHOR]
