Prehospital patient care decisions should be based on __________.

• A. the opinions of physicians
• B. the experiences of EMTs
• C. EMS research
• D. an EMS agency's fiscal resources

Answer: (C)

Evidence-based practice guides prehospital care decisions. In EMS, the most reliable basis for choosing interventions is EMS research—the best available, scientifically tested evidence about what works, what doesn’t, and what’s safe in real field conditions. This approach helps standardize care, improve patient outcomes, and reduce unnecessary variation that can come from anecdotes or personal experience.

While physician input and EMT experience are valuable for clinical judgment, they reflect individual perspectives and can be biased or not generalizable. Fiscal resources influence what can be implemented, but decisions should still be driven by solid evidence to ensure patient benefit. Therefore, using EMS research as the foundation ensures care choices are grounded in proven effectiveness and safety.
