Evidence-based medicine guides patient care by combining the best available research evidence with clinical expertise and the patient’s values and preferences to make informed, individualized decisions. It uses high-quality evidence from well-designed studies and systematic reviews, interprets how that evidence applies to the patient’s unique situation, and then engages the patient in shared decision-making about options, benefits, and risks. This approach emphasizes not only what the data show, but also how it fits with the clinician’s experience and the patient’s goals, tolerances for risk, and overall circumstances. Relying on personal opinions alone, ignoring patient values, or focusing only on trial size misses the essential integration of evidence, expertise, and patient-centered factors that guide optimal care.
