Orthopaedists often speculate how weather and school schedule may influence pediatric orthopedic trauma volume, but few studies have examined this. This study aims to determine: how do weather patterns, day, month, season and public school schedule influence the daily frequency of pediatric orthopedic trauma consults and admissions?
With IRB approval, orthopedic trauma data from a level 1 pediatric trauma center, including number of daily orthopedic trauma consults and admissions, were collected from July 2009 to March 2012. Historical weather data (high temperatures, precipitation and hours of daylight), along with local public school schedule data were collected for the same time period. Univariate and multivariate regression models were used to show the average number of orthopedic trauma consults and admissions as a function of weather and temporal variables.
High temperature, precipitation, month and day of the week significantly affected the number of daily consults and admissions. The number of consults and admissions increased by 1% for each degree increase in temperature (p=0.001 and p<0.001, respectively), and decreased by 21% for each inch of precipitation (p<0.001, p=0.006). Daily consults on snowy days decreased by an additional 16% compared to days with no precipitation. November had the lowest daily consult and admission rate, while September had the highest. Daily consult rate was lowest on Wednesdays and highest on Saturdays. Holiday schedule was not independently significant.
Pediatric orthopedic trauma consultations and admissions are highly linked to temperature and precipitation, as well as day of the week and time of year.
骨科医生常常推测天气和学校日程安排可能如何影响小儿骨科创伤量，但很少有研究对此进行过探讨。本研究旨在确定：天气模式、日期、月份、季节和公立学校日程安排如何影响小儿骨科创伤会诊和住院的每日频次？
经机构审查委员会批准，收集了一家一级小儿创伤中心2009年7月至2012年3月的骨科创伤数据，包括每日骨科创伤会诊和住院的数量。同时收集了同一时期的历史天气数据（高温、降水量和日照时长）以及当地公立学校日程安排数据。使用单变量和多变量回归模型来显示骨科创伤会诊和住院的平均数量作为天气和时间变量的函数。
高温、降水量、月份和星期几对每日会诊和住院数量有显著影响。温度每升高1度，会诊和住院数量分别增加1%（p=0.001和p<0.001），降水量每增加1英寸，会诊和住院数量分别减少21%（p<0.001，p=0.006）。与无降水日相比，雪天的每日会诊量额外减少16%。11月的每日会诊和住院率最低，而9月最高。每日会诊率在周三最低，在周六最高。节假日日程安排并无独立的显著影响。
小儿骨科创伤会诊和住院与温度、降水量以及星期几和一年中的时间密切相关。
