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.

Healthcare terminology is a collective term for the range from code sets and classifications to nomenclatures and structured vocabularies. This post explains the HIMSS Dictionary definition, then reviews five studies: a Korean survey of 325 professionals that found low knowledge of SNOMED CT and LOINC, a nursing study that mapped 1,271 patient education titles to SNOMED CT with 3.9 percent unmapped, a Dutch framework for maintaining terminologies, a study of junior learners and jargon, and a review of evidence-based healthcare terms.

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.

A payer is an outside organization that funds or insures healthcare costs, from insurers and managed care plans to ACOs, government programs, and administrators. This post explains the HIMSS Dictionary definition and the 2024 national spending figures from CMS, then reviews four 2026 studies: interviews with nine health system and payer leaders on digital tool adoption, a payer-perspective model of stroke rehabilitation costs, a Greek dialysis micro-costing study, and an all-payer analysis of 77,248 patients.

An indicator is a measurable variable that shows how closely care meets a standard or how much quality has been achieved.
