Clinical Informatics Fundamentals and Core Concepts
Core concepts
Know the definition and scope of clinical informatics: the use of data, information, and knowledge to improve health and care. Understand the DIKW hierarchy (data → information → knowledge → wisdom) and the informatics model of people, process, and technology. Learn the core competencies: clinical, technical, and organizational. Understand the distinction between informatics and IT - informatics focuses on clinical workflow and information use, IT on infrastructure. Know the role of the informaticist in translating clinical needs into system requirements.
Traps
Questions often conflate informatics with IT or with data science. Another trap: assuming the DIKW hierarchy implies linear progression - in practice, context determines meaning. Also watch for confusion between data, information, and knowledge in scenario questions.
Rule of thumb
Informatics sits at the intersection of people, process, and technology; if a solution addresses only technology, it is incomplete.
Worked example
A clinician asks for a new report. The informaticist first clarifies the clinical decision the report will support, then identifies the data source, then designs the output. The technology is the last step, not the first.
