NURS6400 answers the foundational question: what exactly is nursing informatics? It is a specialty that integrates nursing science with multiple information and analytical sciences to identify, define, manage, and communicate data, information, knowledge, and wisdom in nursing practice. NURS6400 establishes this definition in its historical, professional, and theoretical context before students proceed to apply informatics concepts in subsequent courses.
Key topics in NURS6400
- History of nursing informatics: Graves & Corcoran's 1989 foundational definition, ANA recognition as a nursing specialty (1992), National League for Nursing informatics competencies, HITECH Act's acceleration of EHR adoption
- DIKW framework: Data (raw facts) → Information (contextualized data) → Knowledge (applied information) → Wisdom (appropriate application of knowledge) — the conceptual foundation of the specialty
- ANA Nursing Informatics: Scope and Standards of Practice (3rd ed.) — competencies expected of all registered nurses, advanced generalist nurses, and nurse informaticists
- TIGER Initiative: Technology Informatics Guiding Education Reform — competency framework for nursing informatics education, focusing on basic computer skills, information literacy, and information management skills
- Nursing informatics roles: nurse informaticist, clinical informatics analyst, CNIO (Chief Nursing Informatics Officer), EHR super-user, informatics educator
- Terminologies: introduction to nursing-specific clinical terminologies — NANDA-I (diagnoses), NIC (interventions), NOC (outcomes), CCC, Omaha System, SNOMED CT, LOINC
- Professional organizations: AMIA (American Medical Informatics Association) Nursing Informatics Working Group, ANIA (American Nursing Informatics Association), HIMSS Nursing Informatics Community
- Ethical dimensions: patient privacy in informatics, data ownership, algorithm bias, equity implications of health IT systems
Working on a nursing informatics foundations paper, DIKW analysis, or competency framework essay?
Our nursing informatics writers develop foundational coursework with the theoretical depth Capella's NURS6400 rubric requires.
The DIKW model applied to clinical practice
- Data: A patient's blood pressure reading: 168/104 mmHg at 14:32 on 6/26/2026
- Information: This reading is stage 2 hypertension (above 140/90 mmHg); it is the third elevated reading this visit
- Knowledge: Stage 2 hypertension requires antihypertensive medication for most patients; lifestyle modification alone is insufficient at this level per JNC 8 guidelines
- Wisdom: Recognizing that this particular patient has medication non-adherence history and white coat hypertension, and choosing to combine ABPM with motivational interviewing before adjusting medication — applying knowledge contextually and ethically
- Nursing informatics role: Designing EHR alerts, order sets, and clinical decision support tools that facilitate the journey from data to wisdom for all nurses in the system

Frequently asked questions
Nursing informatics has been developing since the 1960s when early computers began being used in clinical settings, but it became a formal ANA-recognized nursing specialty in 1992 — the year the ANA published the first Scope of Practice for Nursing Informatics. The foundational definition was articulated by Graves and Corcoran in their landmark 1989 paper: "A combination of computer science, information science, and nursing science designed to assist in the management and processing of nursing data, information and knowledge to support the practice of nursing and the delivery of nursing care." The specialty has grown dramatically since then, accelerated by the HITECH Act of 2009 (which provided financial incentives for EHR adoption) and the ACA (which tied reimbursement to quality measures requiring health IT infrastructure). Today, CNIO (Chief Nursing Informatics Officer) is a C-suite position in many health systems.
Standardized nursing terminologies are essential to nursing informatics because they enable structured, computable data capture of nursing assessments, diagnoses, interventions, and outcomes — making nursing work visible and measurable in EHR data. Key terminologies include: NANDA-I (North American Nursing Diagnosis Association International) — standardized nursing diagnosis labels; NIC (Nursing Interventions Classification) — standardized nursing intervention terms; NOC (Nursing Outcomes Classification) — standardized patient outcome terms. Together, NANDA-I/NIC/NOC form a triad for documenting the nursing process. Beyond these nursing-specific terminologies, nurse informaticists must understand SNOMED CT (the comprehensive clinical terminology used in EHRs), LOINC (for laboratory and clinical observations), ICD-10-CM (diagnoses for billing), and CPT (procedures for billing). Interoperability requires mapping between these terminologies, a skill that nurse informaticists develop throughout the MSN program.
MSN Nursing Informatics graduates pursue roles including: Clinical Informatics Analyst (working with clinical teams to optimize EHR workflows, build order sets, configure CDS alerts); Implementation Specialist (leading EHR or health IT system implementations for vendor companies or health systems); Informatics Educator (training nurses and other clinicians on EHR and health IT systems); Clinical Systems Analyst (requirements gathering, system testing, go-live support); Nursing Informatics Consultant (independent consulting on EHR optimization, workflow design, informatics governance); and, with experience, CNIO or VP of Clinical Informatics (executive leadership of clinical informatics strategy). The specialty's demand has grown substantially: the explosion of health IT since HITECH and the complexity of modern EHR systems have created strong demand for nurses who bridge clinical expertise and information technology.
