What practice is characterized by the delivery of services based on established clinical research?

The practice characterized by the delivery of services based on established clinical research is known as Evidence-Based Care. This approach integrates the best available research evidence with clinical expertise and patient values to guide decision-making in healthcare. By utilizing systematic reviews and clinical trials, evidence-based care ensures that treatments provided are grounded in proven effectiveness, minimizing variations in practice and optimizing outcomes for patients.

In this context, while standardized care refers to a uniform approach to treatment protocols that might be used within a specific setting, it does not exclusively rely on current clinical research as evidence-based care does. Clinical practice guidelines, although related to evidence-based care, are more about the structured recommendations derived from evidence, rather than the practice of applying that evidence directly in patient care scenarios. Expert opinion care relies on the insights and judgments of experienced professionals but does not necessarily rely on empirical evidence from clinical research, making it less robust than evidence-based care.
