To analyze emergency department (ED) mental health presentations over a 7-year period to estimate the timing and magnitude of the seasonal effect across Australia. We analyzed data collected by the Australian Institute of Health and Welfare (AIHW) from 2014-2015 to 2020-2021, which included all public hospital ED presentations in Australia that received a mental health diagnosis per the Australian Modification of . The data were divided into 4 sequential quarters (Q1 = July-September, Q2 = October-December, Q3 = January-March, Q4 = April-June) and analyzed by sex and age (youth: 18-24 years, adult: 25-64 years, and older adult: > 65 years). Regression analysis was used to assess seasonal variation. On average, mental health ED presentations were 9% higher in October-December than April-June, which had the lowest rates of mental health ED presentations for males and females. The peak continued into January-March, most prominently for females. Seasonality was evident in the 18-24 and 25-64 age groups. There were increased ED psychiatry presentations in October-December of 14.4% (males) and 9% (females) in the group aged 18-24, as well as increases of 10.3% (males) and 10.1% (females) in those aged 25-64. In January-March, there was an increase in presentations for females of 7% (aged 18-24) and 10.3% (aged 25-64). For adults aged > 65, there were increased presentations in July-September compared to April-June of 4.9% (males) and 3.9% (females). We found strong, statistically significant peaks in mental health ED presentations in spring and summer. Mental health services need to plan for significantly higher ED mental health demand during these seasons. Further research is required to estimate the size of the mental health seasonal effect in acute hospital settings. .
分析7年期间急诊科心理健康就诊情况，以估计澳大利亚季节性效应的时间和程度。我们分析了澳大利亚卫生与福利研究所（AIHW）在2014 - 2015年至2020 - 2021年期间收集的数据，其中包括澳大利亚所有公立医院急诊科根据澳大利亚修改版进行心理健康诊断的就诊情况。数据被分为4个连续季度（第一季度 = 7月至9月，第二季度 = 10月至12月，第三季度 = 1月至3月，第四季度 = 4月至6月），并按性别和年龄（青年：18 - 24岁，成年人：25 - 64岁，老年人：> 65岁）进行分析。采用回归分析评估季节性变化。平均而言，10月至12月的心理健康急诊科就诊人数比4月至6月高9%，4月至6月是男性和女性心理健康急诊科就诊率最低的时期。高峰期持续到1月至3月，女性最为明显。季节性在18 - 24岁和25 - 64岁年龄组中很明显。18 - 24岁年龄组在10月至12月的急诊科精神病就诊人数增加，男性增加14.4%，女性增加9%，25 - 64岁年龄组的男性增加10.3%，女性增加10.1%。在1月至3月，18 - 24岁女性就诊人数增加7%，25 - 64岁女性增加10.3%。对于65岁以上的成年人，7月至9月的就诊人数比4月至6月增加，男性增加4.9%，女性增加3.9%。我们发现春季和夏季心理健康急诊科就诊人数出现了强烈的、具有统计学意义的高峰。心理健康服务需要为这些季节期间显著更高的急诊科心理健康需求做好规划。需要进一步研究来估计急性医院环境中心理健康季节性效应的规模。
