Abstract
Background:
As mass participation events continue to increase in popularity, the need for medical care continues to increase. Our objective was to evaluate the course medical tent usage throughout the Bank of America Chicago Marathon course. Our second objective was to evaluate emergency medical services (EMS) utilization during the event.
Hypothesis:
We hypothesize that as the race progresses, medical tents will see more participants and EMS will have an increase in utilization.
Level of Evidence:
Level 4.
Methods:
This study was a retrospective analysis of data collected by the medical staff from 2015 to 2017. Documented patient encounters were analyzed from each course medical tent. Twenty medical tents were spaced roughly 1.2 miles apart depending on location and ease of EMS access to the medical tent location.
Results:
From 2015 to 2017, the course medical tents saw 2973 patients, with a 96.3% discharge rate. The data showed a linear increase of 5.69 patients seen per mile until mile 20 (linear regression P < 0.01). After mile 20, the number of patients seen per mile was about the same. The data also showed an increase in EMS utilization every 5 miles as the race progressed (P = 0.04) and an increase in ratio of patients transported to the hospital compared with patients transferred to the main medical tents up to mile 20 (P = 0.02).
Conclusion:
Course medical tents saw a statistically significant linear increase in patients per mile until mile 20. Total EMS utilization showed a statistically significant increase in usage as the race progressed and a statistically significant increase in ratio of transports to transfers as the race progressed until mile 20.
Clinical Relevance:
This study has the potential to influence medical tent and EMS placement for endurance events with increasing patient encounters and hospital transports as the mileage of the endurance event increases.
