Popular emergency room wisdom touts higher temperatures, snowfall, weekends, and evenings as variables that increase trauma admissions. This study analyzed the possible correlation between trauma admissions and specific weather variables, and between trauma admissions and time of day or season.
Trauma admission data from a Level I trauma center database from July 1, 1996 to January 31, 2002 was downloaded and linked with local weather data from the Archives of the National Oceanic and Atmospheric Administration website, and then analyzed.
There were 8,269 trauma admissions over a total of 48,984 hours for an average of one admission every 6 hours. Daily high temperature and precipitation were valid predictors of trauma admission volume, with a 5.25% increase in hourly incidents for each 10-degree difference in temperature, and a 60% to 78% increase in the incident rate for each inch of precipitation in the previous 3 hours.
Weather and seasonal variations affect admissions at a Level I trauma center. Data from this study could be useful for determining staffing requirements and resource allocation.
急诊室普遍认为，高温、降雪、周末和夜间是导致创伤入院人数增加的因素。本研究分析了创伤入院人数与特定天气变量之间，以及创伤入院人数与一天中的时间或季节之间的可能相关性。
下载了1996年7月1日至2002年1月31日一级创伤中心数据库中的创伤入院数据，并将其与美国国家海洋和大气管理局网站档案中的当地天气数据相链接，然后进行分析。
在总共48984小时内有8269例创伤入院病例，平均每6小时有1例入院。每日高温和降水量是创伤入院量的有效预测指标，温度每相差10度，每小时入院事件增加5.25%，前3小时每英寸降水量的入院率增加60%至78%。
天气和季节变化会影响一级创伤中心的入院人数。本研究的数据可用于确定人员配备需求和资源分配。
