The main idea is that evidence-based medicine seeks to guide decisions by combining the best available research with what you know from clinical experience and what matters to the patient. It isn’t enough to just follow studies in isolation or to rely solely on what experts think. The most useful approach uses high-quality research, but adjusts that information through the clinician’s hands-on experience and the patient’s values, preferences, and circumstances. This helps tailor decisions to each individual rather than applying a one-size-fits-all rule.

Expert opinion alone can be biased or outdated because it doesn’t always reflect the newest or strongest evidence. Focusing only on cost-effectiveness misses the patient’s values and the clinical context, which are essential for choosing a treatment that aligns with the patient’s goals. And looking only at study size ignores study quality, design, and applicability; a large study isn’t automatically the best evidence if its methods are weak or its population isn’t relevant to the patient.
