Our objective is to identify seasonal and weather trends associated with pediatric trauma admissions.


We reviewed all trauma activations leading to admission in patients ≤18 years admitted to a regional pediatric trauma center from January 1, 2000, to December 31, 2015. We reviewed climatologic measures of the mean temperature, mean visibility, and precipitation for each admission in the 6 h prior to each presentation in addition to time of arrival, weekday/weekend presentation, and season. We used a negative binomial regression model with multivariable analysis to estimate associations between weather and rate of trauma admissions. Results were presented as incidence rate ratios (IRR) with 95% confidence intervals (CI).


In total, 3856 encounters [2539 males (65.8%), mean age 10.2 years ± SD 5.1 years] were included. Results from multivariable analysis (IRR, 95% CI) suggested an association of admissions with rain (0.82, 0.75–0.90) and overnight hours (23:51–05:50; 0.69, 0.58–0.82) as compared to morning (05:51–11:50). The IRR of trauma increased during the afternoon (11:51–17:50; 4.05, 3.57–4.61), night periods (17:51–23:50; 5.59, 4.94–6.33), and weekends (1.24, 1.15–1.32), and with every 1 °C increase in temperature (1.04, 1.03–1.04). After accounting for other variables, season was not found to be independently predictive of trauma admission.


Trauma admissions had a higher rate during afternoon, evening hours, and weekends. The presence of rain lowered the rate of pediatric trauma admission. Each degree increase in temperature increased the rate of trauma admissions by 4%. The findings provide information from the perspective of emergency preparedness, resource utilization, and staffing to pediatric trauma centers.
