Abstract

Background

Public holidays and weekends are periods with changes in lifestyle and capacity of healthcare services, and there may be impact on the risk of out-of-hospital cardiac arrest (OHCA) and OHCA outcomes.

Objectives

We aim to investigate the association of public holidays and weekends on the risk of OHCA and mortality in a multi-ethnic Asian population in Singapore.

Methods

We included all nationally reported cases of OHCA from 1 April 2010 to 31 December 2021. Using negative binomial regression models, adjusting for possible confounders, we estimated the non-linear and lagged effects of public holidays and day of the week on the risk of OHCA and mortality. Public holidays were further categorised into traditional holidays, religious holidays and non-religious holidays.

Results

In the study period, 28,660 cases of OHCA were included, of which 948 (3.3 %) occurred on a public holiday and 8459 (29.5 %) on a weekend, 18,286 (63.7 %) were male and 18,895 (67.9 %) were of Chinese ethnicity. The holidays with the highest proportion of OHCA were Chinese New Year over 2 days (20.4 %) and Hari Raya Puasa (10.3 %). The days with highest proportion of OHCA were Saturday (15.0 %), Sunday (14.5 %) and Monday (14.5 %). Any public holiday was associated with increased risk of OHCA compared to non-public holidays (Lag 0: adjusted RR 1.104, SE 0.035, p = 0.004; Lag 1: adjusted RR 1.072, SE 0.035, p = 0.046) and increased risk of mortality (adjusted RR 1.107, SE 0.036, p = 0.004). The weekend was also associated with significantly higher risk of OHCA (adjusted RR 1.047, SE 0.013, p = 0.001) and mortality (adjusted RR 1.044, SE 0.014, p = 0.002) compared to weekdays.

Conclusions

Public holidays and weekends were associated with increased risk of OHCA and mortality, particularly for traditional holidays such as Chinese New Year and Hari Raya Puasa.

公共假期和周末院外心脏骤停和死亡率的风险：一项时间序列研究

背景：公共假期和周末是生活方式和医疗保健服务能力发生变化的时期，可能会影响院外心脏骤停（OHCA）的风险和OHCA结局。目的：我们的目的是调查公共假期和周末与新加坡多种族亚洲人群OHCA风险和死亡率的关系。方法：我们纳入了2010年4月1日至2021年12月31日全国报告的所有OHCA病例。使用负二项回归模型，调整了可能的混杂因素，我们估计了公共假期和一周中的哪一天对OHCA风险和死亡率的非线性和滞后影响。公众假期进一步分为传统节日、宗教节日和非宗教节日。结果：研究期间共纳入28660例OHCA，其中节假日948例（3.3%），周末8459例（29.5%），男性18286例（63.7%），华裔18895例（67.9%）。OHCA比例最高的假期是春节2天以上（20.4%）和开斋节（10.3%）。OHCA比例最高的日子是周六（15.0%）、周日（14.5%）和周一（14.5%）。与非公共假期相比，任何公共假期都与OHCA风险增加相关(Lag 0：调整后RR 1.104, SE 0.035, p=0.004；滞后1：调整后的RR为1.072，SE为0.035,p=0.046)，死亡风险增加（调整后的RR为1.107，SE为0.036,p=0.004）。与工作日相比，周末的OHCA风险（校正后RR为1.047，SE为0.013,p=0.001）和死亡率（校正后RR为1.044，SE为0.014,p=0.002）也显著增加。结论：公共假期和周末与OHCA和死亡率的风险增加有关，特别是在传统节日，如中国新年和开斋节。

期刊介绍： Resuscitation is a monthly international and interdisciplinary medical journal. The papers published deal with the aetiology, pathophysiology and prevention of cardiac arrest, resuscitation training, clinical resuscitation, and experimental resuscitation research, although papers relating to animal studies will be published only if they are of exceptional interest and related directly to clinical cardiopulmonary resuscitation. Papers relating to trauma are published occasionally but the majority of these concern traumatic cardiac arrest.
