It is widely believed that patients are less likely to visit hospitals during bad weather. We hypothesized that weather and emergency department (ED) visits are associated. Thus, we investigated the association between pediatric ED visits and weather, and sought to determine whether admissions to the ED are affected by meteorological factors.
We retrospectively analyzed all 87,242 emergency visits to Samsung Changwon Hospital by pediatric patients under 19years of age from January 2005 to December 2014. ED visits were categorized by disease. We used Poisson regression and generalized linear model to examine the relationships between current weather and ED visits. Additionally a distributed lag non-linear model was used to investigate the effect of weather on ED visits.
During this 10-year study period, the average temperature and diurnal temperature range (DTR) were 14.7°C and 8.2°C, respectively. There were 1,145days of rain or snow (31.4%) during the 3,652-day study period. The volume of ED visits decreased on days of rain or snow. Additionally ED visits increased 2days after rainy or snowy days. The volume of ED visits increased 1.013 times with every 1°C increase in DTR. The volume of ED visits by patients with trauma, digestive diseases, and respiratory diseases increased when DTR was over 10°C. As rainfall increased to over 25mm, the ward admission rate (23.8%, p=0.018) of ED patients increased significantly.
The volume of ED visits decreased on days of rain or snow and the ED visits were increased 2days after rainy or snowy days. The volume of ED visits increased for every 1°C increase in DTR.
人们普遍认为，天气恶劣时患者不太可能去医院。我们假设天气和急诊科（ED）就诊之间存在关联。因此，我们调查了儿科 ED 就诊与天气之间的关系，并试图确定气象因素是否会影响 ED 的住院率。
我们回顾性分析了 2005 年 1 月至 2014 年 12 月期间三星昌原医院 19 岁以下儿科患者的 87242 例急诊就诊记录。根据疾病对 ED 就诊进行分类。我们使用泊松回归和广义线性模型来检查当前天气与 ED 就诊之间的关系。此外，还使用分布滞后非线性模型来研究天气对 ED 就诊的影响。
在这项为期 10 年的研究期间，平均气温和日温差（DTR）分别为 14.7°C 和 8.2°C。在 3652 天的研究期间，有 1145 天下雨或下雪（31.4%）。雨天或雪天，ED 就诊量减少。此外，雨或雪后天就诊量增加 2 天。DTR 每增加 1°C，ED 就诊量增加 1.013 倍。DTR 超过 10°C 时，创伤、消化和呼吸疾病患者的 ED 就诊量增加。当降雨量增加到超过 25mm 时，ED 患者的住院率（23.8%，p=0.018）显著增加。
雨天或雪天 ED 就诊量减少，雨或雪后天就诊量增加 2 天。DTR 每增加 1°C，ED 就诊量增加 1.013 倍。
