In case you haven't heard, you can now get board certified in clinical informatics. Clinical Informatics is a subspecialty within the American Board of Preventive Medicine (ABPM). Right now, you can either go through a formal fellowship in informatics or you can demonstrate expertise based on your working experience.
Starting in 2018, all applicants for certification in Clinical Informatics will have to complete successfully a minimum of 24 months in an ACGME-accredited Clinical Informatics fellowship program.
Physicians who practice Clinical Informatics collaborate with other health care and information technology professionals to analyze, design, implement and evaluate information and communication systems that enhance individual and population health outcomes, improve patient care, and strengthen the clinician-patient relationship. Clinical Informaticians use their knowledge of patient care combined with their understanding of informatics concepts, methods, and tools to: assess information and knowledge needs of health care professionals and patients; characterize, evaluate, and refine clinical processes; develop, implement, and refine clinical decision support systems; and lead or participate in the procurement, customization, development, implementation, management, evaluation, and continuous improvement of clinical information systems.You can read more about this here.
