The study aims to examine the geographic variation in prehospital time among trauma patients at risk of hemorrhagic shock.
Analyzed 2020–2023 data from the National EMS Information System (NEMSIS)
Included patients aged ≥16 years at risk of hemorrhagic shock with shock index ≥1
Compared prehospital time across urban, suburban, rural, and wilderness areas
Assessed transport time differences between ground and air modes
Median prehospital time increased from urban (39 min) to wilderness (56 min) areas
Longer components of prehospital time were evident in rural and wilderness regions
Air transport time was consistently longer than ground time (p < .001)
Total prehospital times showed minor year-to-year variation
