About This Series: The HIMSS Word of the Day is a running blog series drawing from the HIMSS Dictionary of Health Information and Technology Terms, Acronyms, and Organizations, 6th Edition (2025) — the authoritative reference for healthcare IT professionals and the primary study resource for CAHIMS and CPHIMS certification. Each post paraphrases the term in plain language, grounds it in real-world healthcare IT context, and adds a bedside nursing perspective you won’t find in a textbook.
📖 The Term: Nursing Informatics
Source: HIMSS Dictionary of Health Information and Technology Terms, Acronyms, and Organizations, 6th Edition (2025)
🔍 Plain-Language Definition
Nursing informatics is the nursing specialty that combines nursing science with computer, information, and analytical sciences. Its job is to help nurses capture, organize, and share the data, information, knowledge, and wisdom that nursing practice depends on.
The HIMSS Dictionary’s definition emphasizes that progression, and so does nearly every textbook in the field. It is often called the DIKW framework, and it builds on work Graves and Corcoran published in 1989 that helped define nursing informatics as a discipline:
| Level | What It Is | Nursing Example |
|---|---|---|
| Data | Discrete, uninterpreted facts | A blood pressure of 88/52 |
| Information | Data placed in context | That reading belongs to a post-op patient whose baseline is 130/80 and who is now tachycardic |
| Knowledge | Information synthesized with clinical understanding | The pattern is consistent with hypovolemia or early sepsis and needs escalation |
| Wisdom | Knowledge applied with judgment to act appropriately | The nurse escalates, initiates the sepsis protocol, and knows which findings to watch next |
Informatics systems are good at the bottom two levels. The top two still depend on nursing judgment, and the specialty exists to design systems that support that judgment instead of burying it.
⚠️ Exam Alert: Distinguish nursing informatics (a nursing specialty focused on nursing practice and data) from clinical informatics (the broader discipline across all clinical professions), health informatics (the widest umbrella, including public health and consumer health), and medical informatics (traditionally physician-focused). Know the DIKW levels in order, and know that the American Nurses Association recognized nursing informatics as a nursing specialty in 1992.
🌐 Why It Matters: Real-World Healthcare IT Context
Nurses are the largest clinical workforce in healthcare and the largest group of EHR users, which makes nursing informatics one of the most consequential roles in any digital health program.
The specialty has formal structure. The American Nurses Association publishes Nursing Informatics: Scope and Standards of Practice, and the American Nurses Credentialing Center offers board certification in informatics nursing (the NI-BC credential). Professional homes include the American Nursing Informatics Association (ANIA), the AMIA Nursing Informatics working group, and the HIMSS Nursing Informatics Community.
Roles span a wide range:
- Super users — staff nurses with extra training who support peers on their own units
- Clinical informatics nurses — nurses who translate unit workflow into build requirements
- Informatics nurse specialists — graduate-prepared or certified nurses who lead design, optimization, and evaluation
- Clinical analysts — nurses working inside IT on build, testing, and support
- Chief Nursing Informatics Officers (CNIOs) — executives who represent nursing in technology strategy and governance
Failure modes when nursing informatics is missing or underpowered:
- Flowsheets and documentation templates designed without nursing input
- Duplicate documentation across narrative notes and structured fields
- Alert and task burden that falls disproportionately on nurses
- Nursing data captured in ways that cannot be reused for quality or research
- Go-Live training that teaches screens rather than workflows
Strengths of mature nursing informatics programs:
- A CNIO or equivalent nursing leader with a seat in IT governance
- Nurse-led documentation governance aligned to standard terminologies
- Super user networks that feed frontline issues back to the build team
- Evaluation of technology by nursing outcomes, including documentation time, falls, pressure injuries, and medication safety
- Education pathways that grow bedside nurses into informatics roles
The specialty also carries a responsibility that pure IT roles do not: informatics nurses remain accountable to nursing’s ethical and professional standards. When a design choice trades nursing time or patient safety for administrative convenience, the informatics nurse is expected to say so, and to bring evidence.
Nursing informatics is how nursing knowledge becomes part of the system rather than a workaround to it.
🏥 The Nurse’s Perspective: Clinical, Bedside, & Workflow
For this term, the nurse’s perspective is not a side angle. It is the definition.
At the Bedside
Every nurse practices informatics on every shift. Choosing which assessment findings to document in structured fields, recognizing when a trend in vital signs means more than any single value, and deciding whether an alert deserves action are all movements up the DIKW ladder.
Bedside nurses also generate the raw material of nursing informatics. When documentation is accurate, timely, and structured, it becomes information other clinicians can trust. When it is rushed, copied forward, or forced into ill-fitting fields, the data looks complete but no longer tells the truth.
In Clinical Workflow
Informatics nurses spend much of their time in the space between the workflow as designed and the workflow as practiced. Shadowing a medication pass, timing an admission assessment, and counting the clicks in a discharge are how they find the gaps. The fixes might be a redesigned flowsheet, a smarter default, a retired alert, or a training tip, and they come from nurses who understand both the floor and the system.
Documentation burden is a central concern. Nurses can spend a large share of each shift documenting, and much of that time goes to fields that exist for regulatory, billing, or quality-reporting reasons rather than for the next nurse caring for the patient. Informatics nurses who can show which fields are actually used, which are duplicated elsewhere, and which no one ever reads are the ones who earn the authority to remove them. Removing a field is often a bigger win than adding a feature.
Standard terminologies are part of this work. Mapping nursing assessments and interventions to codes such as SNOMED CT and LOINC lets nursing data be compared across units and organizations, and it makes the value of nursing care visible in the data.
In EHR Implementation (Go-Live Perspective)
Epic Go-Lives depend on nurses at every stage: subject matter experts in design sessions, testers who run real workflows before cutover, super users at the elbow, and informatics nurses who triage issues in the command center. Many informatics careers begin exactly here, when a staff nurse volunteers as a super user and discovers a talent for translating between clinicians and analysts.
End-user support during Go-Live is where nursing informatics is most visible. Separating a training gap from a build defect, and a build defect from a workflow that was never right to begin with, is informatics judgment at work under pressure.
