American Heart Association protocols are based on __________.

• A. theories ready for field trial
• B. trends in the EMS community
• C. evidence-based research
• D. opinions from a core group of cardiologists

Answer: (C)

The key idea is that American Heart Association protocols are built from evidence-based research. This means guidelines are grounded in systematically gathered and critically appraised scientific data from high-quality studies—such as randomized controlled trials, observational studies, and meta-analyses—and then assessed for how strongly they support specific recommendations. Panels review this body of evidence, weigh the benefits and risks, and translate it into practical rules for practice. Because new research can change what’s most effective, these guidelines are updated to reflect the best current evidence. They aren’t based on theoretical ideas, trends in the EMS field, or a single group’s opinions, but on solid data drawn from many studies.
