In a study conducted in Kochi Prefecture, Shikoku, Japan, during the early stages of the pandemic in spring 2020, we found that emergency transportations due to acute alcohol intoxication decreased. We aimed to determine how the decline in the number of emergency transportations due to acute alcohol intoxication changed during the four years following the COVID-19 pandemic's onset.
This study used data of 107,013 emergency transportations from the Kochi-Iryo-Net database, Kochi Prefecture's emergency medical and wide-area disaster information system. We categorized emergency transportation cases according to the diagnoses entered into the system by the attending physician, which were then divided into alcohol- and non-alcohol-related intoxication cases based on the diagnostic codes in the International Classification of Diseases Manual, 10th edition, Clinical Modification. We performed chi-square tests and multiple logistic regression to examine the association between emergency transportations and acute alcohol intoxication.
The number of emergency transportations due to acute alcohol intoxication was 412 (1.8%) in 2019, and it declined to 268 (1.4%), 248 (1.2%), 270 (1.2%), and 283 (1.3%) in 2020, 2021, 2022, and 2023, respectively. After adjusting for confounding factors such as fire department and age, a significant decrease was observed in the subsequent years compared with 2019 (2020: adjusted odds ratio, 0.79; 95% confidence interval, 0.68-0.93; 2021: adjusted odds ratio, 0.74; 95% confidence interval, 0.63-0.87; 2022: adjusted odds ratio, 0.73; 95% confidence interval, 0.62-0.85; 2023: adjusted odds ratio, 0.76; 95% confidence interval, 0.65-0.89).
This study examined changes in emergency transportation due to acute alcohol intoxication during and after the COVID-19 pandemic, especially when social events and other activities returned to "normal." Compared with 2021, which was when emergency transportations due to acute alcohol intoxication were at their lowest, a slight increase was observed in the number of transportations in subsequent years.
在 2020 年春季日本四国地区高知县进行的大流行早期研究中，我们发现因急性酒精中毒而进行的紧急转运减少了。我们旨在确定 COVID-19 大流行开始后的四年中，因急性酒精中毒而减少的紧急转运数量如何变化。
本研究使用了高知县急救医疗和广域灾害信息系统的 Kochi-Iryo-Net 数据库中的 107013 例急救转运数据。我们根据主治医生输入系统的诊断对急救转运病例进行了分类，然后根据国际疾病分类手册，第 10 版，临床修正版中的诊断代码将其分为酒精中毒和非酒精中毒病例。我们进行了卡方检验和多因素逻辑回归，以检查急救转运与急性酒精中毒之间的关联。
2019 年因急性酒精中毒而进行的急救转运数量为 412 例（1.8%），2020 年、2021 年、2022 年和 2023 年分别降至 268 例（1.4%）、248 例（1.2%）、270 例（1.2%）和 283 例（1.3%）。在调整了消防部门和年龄等混杂因素后，与 2019 年相比，随后几年的转运数量显著减少（2020 年：调整后的优势比，0.79；95%置信区间，0.68-0.93；2021 年：调整后的优势比，0.74；95%置信区间，0.63-0.87；2022 年：调整后的优势比，0.73；95%置信区间，0.62-0.85；2023 年：调整后的优势比，0.76；95%置信区间，0.65-0.89）。
本研究检查了 COVID-19 大流行期间和之后因急性酒精中毒而导致的急救转运变化，特别是在社交活动和其他活动恢复“正常”时。与因急性酒精中毒而进行的急救转运数量最低的 2021 年相比，随后几年的转运数量略有增加。
