Which informatics domain uses computer and information science to discover new knowledge relating to health and disease?

• A. Clinical Health Care Informatics
• B. Translational Bioinformatics
• C. Public Health Informatics
• D. Clinical Research Informatics

Answer: (D)

Translational bioinformatics focuses on turning biological data into knowledge that can directly inform patient care. It uses computer and information science to integrate omics data (genomics, proteomics, etc.) with clinical information, with the goal of uncovering new insights about health and disease, identifying biomarkers, understanding disease mechanisms, and guiding diagnostics and therapies. This emphasis on translating basic science findings into clinically useful knowledge is what sets it apart from the other domains. Clinical health care informatics centers on improving care delivery and decision support within clinical settings; public health informatics deals with population health surveillance and policy; clinical research informatics supports the design and management of research studies. So the domain best described by using informatics to discover new knowledge related to health and disease is translational bioinformatics.
