Biomedical informatics is the interdisciplinary field that studies how to use biomedical data, information, and knowledge to support science, problem solving, and decisions that improve health. This post explains the HIMSS Dictionary entry, which matches the definition adopted by AMIA, then reviews five sources on how the field is defined, taught, and certified, along with a gap analysis of graduate curricula.

Ancillary care is the wide set of services around the main medical visit, which the HIMSS Dictionary groups into diagnostic, therapeutic, and custodial services. This post explains the entry and how the term is used differently elsewhere, then reviews five sources: order fulfillment at Kaiser Permanente, a review of pressure injury risk in ancillary units, a colocated services study, lessons from four CPOE rollouts, and a narrative paper on pediatric services.

The TIGER Initiative is a nursing-rooted effort to bring informatics into education and practice across health professions. This post explains the HIMSS Dictionary entry, then uses HIMSS pages, a 2014 news report, and two peer-reviewed papers to trace its history from 2006, its international competency frameworks, and its current form as the HIMSS TIGER Global Community, which uses a newer name than the Dictionary does.

The Perioperative Nursing Data Set (PNDS) is a standardized nursing vocabulary for care around surgery, covering the time before admission through discharge. This post explains the HIMSS Dictionary definition, then reviews six sources: EMR integration at one health system, a Korean translation tested with 142 nurses, a Finnish test with 250 patients, a third-edition revision, a 114-element health system domain, and a systematic review of nursing terminologies.

A medical device interface is every point where a person and a device meet, from unpacking and calibration to daily use and cleaning. This post explains the HIMSS Dictionary definition, then reviews studies of home-use devices, a heuristic evaluation that found 43 usability problems in a smart pump, nurses’ views of two pump interfaces, a pediatric ICU pump comparison, and a review on human factors in procurement.

A patient record is the organized history of a patient’s health kept by a physician, nurse, or other practitioner. This post explains the HIMSS Dictionary definition, then reviews five 2026 studies: a technology acceptance model tested on Germany’s national electronic patient record (ePA) with 149 valid responses, an interview study of 23 users who tried to access the ePA through insurer apps, a FHIR-based research patient record dashboard, an Epic-integrated COPD self-management app co-designed over six improvement cycles, and 45 leader interviews on record implementation and hospital consolidation.

The Nursing Outcome Classification (NOC) is a standard list of patient outcomes that lets nurses judge whether their interventions worked. This post explains the HIMSS Dictionary definition and how NOC works with NANDA-I diagnoses and NIC interventions, then reviews five studies: linkage work for risk for thrombosis (61 terms) and risk for elder frailty syndrome, a Korean nursing home study of seven frequent linkages, a validation of a neurological status outcome with 13 indicators, and a postoperative health index built from NOC labels.

The Clinical Care Classification (CCC) is a standardized, coded nursing terminology that captures the discrete elements of nursing practice. This post explains the HIMSS Dictionary definition and the CCC System’s structure, then reviews four sources: the system’s own description of 21 care components and four levels, a 2025 scoping review of 60 studies, a 2026 evaluation of a large language model that mapped ICU nursing notes to CCC terms, and a 2026 study that found low compatibility between emergency nursing records and the CCC cardiac component.

Bar coding uses scannable symbols to identify an item, and it is the most common form of automatic identification used for data capture. This post explains the HIMSS Dictionary definition, then reviews six sources: a 2026 FDA final rule on National Drug Code and drug label barcode requirements, a randomized trial of bar-coded surgical sponges, a transfusion laboratory study where full scanning occurred in 33.6 percent of 6,285 collections, a 16-month study of medication scanning across five wards, a transfusion check in 58 operating rooms, and a Safety-II look at workarounds.

Free text is information written as ordinary sentences, without codes or fixed fields. This post explains the HIMSS Dictionary definition and the trade-off between narrative and structured entry, then reviews six sources: a content analysis of serious illness conversations documented two ways, a three-system study of advance care planning in 435 cancer patients, a measure of social determinants data use in 27,127 patients, a study of nurses’ free-text notes after early warning scoring, a comparison of MRI report formats, and an evaluation of 17 language models on nursing notes.

A flow sheet is a tabular summary of information arranged to display the values of variables as they change over time. In the EHR it is the main place where nurses chart vital signs, assessments, intake and output, and other repeated measures. This post explains the HIMSS Dictionary definition, then reviews six sources: nurse interviews on flowsheet documentation burden, a workflow redesign that cut reassessment steps by 88 to 97 percent, a pipeline that aligned flowsheets across two sites, a test of generative AI on flowsheet data, a breastfeeding data preparation study of 33,285 dyads, and a randomized crossover trial of a spatial alternative to the linear flowsheet.

A critical pathway is a tool that supports collaborative, coordinated practice by providing for multidisciplinary communication, care planning, and documentation of caregivers’ evaluations and assessments. This post explains the HIMSS Dictionary definition, then reviews five sources: a 2025 Cochrane review of clinical pathways in 58 studies, a review of barriers to care pathways in primary care, a systematic review of integrated care pathways, an evaluation of 41 nurse-initiated care protocols in an emergency department, and a meta-analysis of two chest pain pathways in 110,933 patient presentations.

An ambulatory care information system is an information system used to improve the quality of care and to bring business systems together in the ambulatory care setting.
