RESUMEN
【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 (12.1±7.8) 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 that 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.
RESUMEN
【Objective】 To analyze the cure time from diagnosis to cure of coronavirus disease 2019(COVID-19). 【Methods】 Based on the time of admission, diagnosis, and discharge of cured cases announced by the provincial and municipal health committees, the average period from diagnosis to discharge was calculated. And based on the aggregate data including the cumulative number of diagnoses, the number of curedcases and the number of deaths and their proportional relationship, we calculated the cure time. 【Results】 The cure time curve of 580 COVID-19 patients had skewed distribution, with a skewness of 1.09, a mean cure time of (14.6±6.7) days, a median of 13 days, and a 95% confidence interval (6.9, 21.0). The average cure time calculated based on the relationship between the cumulative number of diagnoses, the number of cured cases and the number of deaths was (13.3±3.5)d, with a median of 13.5 d. The average value of the cure time calculated based on the proportion of cured cases to the number of endpoints was (14.2±4.2)d, with the median number of 14.5 d. Based on the calculation of the relationship between the cumulative number of diagnosed cases, the number of cured cases and the number of deaths, the median cure time of cases with COVID-19 in Wuhan, Hubei Province, and the whole country was 15 days, 15.5 days and 15 days, respectively. The mediancure time for COVID-19cases in Wuhan, Hubei, and the whole country was 14 days. 【Conclusion】 The median cure time of COVID-19 is 13-15.5 days. There is some variation at different time of the outbreak, but there is not much difference between different regions.
