Effect of weather on medical patient volume at Kansas Speedway mass gatherings[1]
Summary
Retrospective review of 22 race days over 6 Kansas Speedway weekends (2007-2010): 1,305 patients, mean encounter rate 13 per 10,000, transfers 0.24 per 10,000. Negative binomial regression: each 1 F rise in daily mean temperature raised total complaints 4% and MAJOR TRAUMA presentations 6%; major trauma was 2.4x more frequent above 63 F; and each inch of precipitation cut total volume 61%.
So what
The motorsport weather quantification with two uncommon findings: heat drives TRAUMA (not just heat illness) at speedways — plausibly via alcohol-exposure hours and behavior — and rain is a demand suppressant worth modeling, not just an inconvenience. Slots beside Perron/Wolin (stadium slopes) as the motorsport panel of the weather-demand evidence.
Key findings
- 22 race days: 13 encounters / 0.24 transfers per 10,000
- +1 F mean temp = +4% complaints, +6% major trauma; trauma 2.4x above 63 F
- Each inch of rain = -61% patient volume
- Heat-trauma link at motorsport venues - beyond heat illness
