Final answer:
Evidence-based medicine (EBM) has emerged as a conceptual anchor term in health care. There is an expectation by health care stakeholders (patients, third-party payers, and health care professionals) for an evidentiary foundation upon which health care decisions should be based. "Evidence-based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research ... especially from patient-centered clinical research". Thus, the current best evidence is not limited to randomized clinical trials (option A).
Step-by-step explanation:
​Evidence-based medicine (EBM) is the integration of individual clinical expertise with the best available external clinical evidence from systematic research, including patient-centered clinical research. When the question refers to the "current best evidence," it means that we are not limited solely to randomized clinical trials, but we also consider other forms of evidence, such as case studies, anecdotal evidence, and practitioner experience.
The key concept in EBM is that no single type of study or source of information holds the monopoly on truth or efficacy when it comes to health care decisions. This perspective allows for a more nuanced and comprehensive approach to health care, considering the complex cultural and personal context in which health care is delivered and received.
Hence, the answer is option A.
