This study aimed to describe the circadian characteristics of hospitalized mortality in order to provide nursing guidance for preventing in-hospital mortality.
A retrospective analysis on inpatient information was implemented.
Harmonic Analysis of Time Series was applied to quantify the periodic structure of the frequency of the occurrence of death.
A total of 3300 cases were included in the present study (male, 63.4% and median age 73 years), including 1540 (46.7%) ICU patients. Incidence of overall hospitalized death exhibited a circadian pattern, presenting peaks from 07:00 to 12:00 and 15:00 to 20:00 P.M., with 21.5% and 13.1% increase above the average at those peak points, respectively. Similarly, the incidence of sudden cardiac death (SCD) showed peaks between 06:00-12:00 and 15:00-20:00, with a 34.7% and 28.0% increase above the average at peak time, respectively. The distribution of death incidence revealed no statistical difference between SCD and non-SCD (p = 0.525).
本研究旨在描述住院死亡率的昼夜节律特征，以便为预防住院死亡率提供护理指导。
对住院患者信息进行回顾性分析。
时间序列谐波分析用于量化死亡发生频率的周期性结构。
本研究共纳入 3300 例病例（男性占 63.4%，中位年龄为 73 岁），包括 1540 例（46.7%）ICU 患者。总的住院死亡率呈现昼夜节律模式，在上午 7:00 至 12:00 和下午 15:00 至 20:00 出现峰值，分别比平均值高出 21.5%和 13.1%。同样，心源性猝死（SCD）的发生率在上午 6:00 至 12:00 和下午 15:00 至 20:00 之间出现峰值，分别比平均值高出 34.7%和 28.0%。死亡发生率的分布在 SCD 和非 SCD 之间没有统计学差异（p=0.525）。
