To describe the effect of Crate Day on alcohol-related presentations (ARPs) to Waikato District Health Board (WDHB) emergency departments (EDs).
This retrospective observational study used a descriptive analytical approach to examine alcohol-related ED attendance. Age standardised ED ARP rates and relative rates (RR) were calculated for the weekends on which crate-day falls (pooled 2019 and 2020) with respect to reference weekends. A sub-group analysis was performed for various age, ethnicity, gender and socio-economic factors.
The age-standardised RR of ARPs for Crate Day weekends relative to the reference weekends was 1.5 (95% confidence interval (CI): 0.96-2.26). The rate of ARPs of 20- to 34-year-olds was significantly higher during Crate Day weekends with a RR of 2.00 (95% CI: 1.11-3.59). There was a disproportionate non-significant increase in ED ARPs in males, those who are living in areas of high deprivation, and people of non-Māori ethnicity on Crate Day weekends compared to reference weekends. Alcohol-related presentations were more frequent (72%) between 5pm and 3am on Crate Day weekends.
The findings from this study suggest an association between ARPs and Crate Day, which varies between demographic groups. Further research is required to determine if this is a reproducible and national finding. Crate Day is a potential target for public health intervention and policy change aimed at reducing alcohol-related harms.
描述 crate day 对怀卡托地区卫生委员会 (WDHB) 急诊部 (ED) 酒精相关就诊的影响。
本回顾性观察研究采用描述性分析方法，检查酒精相关 ED 就诊情况。对于 crate-day 所在的周末（汇总 2019 年和 2020 年），计算了年龄标准化 ED 酒精相关就诊率和相对比率 (RR)，并与参考周末进行比较。对不同年龄、种族、性别和社会经济因素进行了亚组分析。
相对于参考周末，crate-day 周末的酒精相关就诊的年龄标准化 RR 为 1.5（95%置信区间 (CI)：0.96-2.26）。20 至 34 岁人群在 crate-day 周末的酒精相关就诊率显著更高，RR 为 2.00（95% CI：1.11-3.59）。与参考周末相比，crate-day 周末 ED 酒精相关就诊率在男性、生活在高贫困地区的人群和非毛利族裔人群中出现不成比例的非显著增加。crate-day 周末，ED 酒精相关就诊更频繁（72%），时间在下午 5 点至凌晨 3 点之间。
本研究结果表明，酒精相关就诊与 crate-day 之间存在关联，且在不同人群中存在差异。需要进一步研究以确定这是否是可重复和全国性的发现。crate-day 是针对减少酒精相关危害的公共卫生干预和政策变化的潜在目标。
