A point-of-care system is a clinical information system that uses bedside workstations, mobile devices, and connected equipment to capture and enter data where patients receive care. This post explains point-of-care documentation and technologies, their benefits for accuracy, timeliness, and safety, research on barriers and the nurse-patient relationship, point-of-care testing, and nursing roles.

A longitudinal health record is a comprehensive summary of a person’s health information across time, organizations, and settings, organized around the patient rather than individual encounters or providers. This post explains how it differs from traditional records, how exchange networks, standards, and apps help assemble it, the challenges of matching and reconciling data, and nursing roles.

Gap analysis compares an organization’s current state with a desired future state to identify the differences and the actions needed to close them. This post explains how gap analysis works, its uses in EHR selection and implementation, workflow redesign, cybersecurity and compliance programs, and maturity assessments, common pitfalls, and the role nurses play.

Electronic data interchange (EDI) is the standardized electronic exchange of business documents between organizations. In healthcare, EDI uses X12 and NCPDP standards adopted under HIPAA for claims, eligibility, remittance, prior authorization, and enrollment. This post explains key transactions, clearinghouses, operating rules, the shift toward FHIR for some processes, and nursing impacts.

Certified EHR technology (CEHRT) is health IT that meets standards and certification criteria adopted by HHS through the ONC Health IT Certification Program and is required for participation in CMS Promoting Interoperability programs. This post explains how certification works, what CEHRT must do, how to verify products on the CHPL, the limits of certification, and what it means for clinicians.

Accountability in health information means being able to identify the person, organization, device, or software responsible for creating, changing, verifying, accessing, disclosing, or transmitting data. This post explains why accountability matters, how unique identification, audit trails, electronic signatures, and provenance support it, challenges with devices and AI, and nursing roles.

Underuse means patients do not receive care that would have benefited them. This post explains how underuse fits with overuse and misuse as categories of quality problems, what research shows about missed recommended care, causes and equity implications, and how quality measures, health IT, and nurses help close gaps.

A trigger event is an occurrence that causes a system to start a response, such as sending a message, firing an alert, or notifying another system. This post explains trigger events in HL7 Version 2 messaging, FHIR subscriptions, and CDS Hooks, how they drive interfaces and decision support, the different meaning of trigger tools in patient safety, and nursing impacts.

Regression testing is the practice of retesting software after changes to confirm that existing functions still work correctly. This post explains why regression testing is critical for EHR upgrades, build changes, and interfaces, how organizations design test scripts around clinical workflows, manual and automated approaches, common failures it catches, and the role of nurses.

The Nursing Minimum Data Set (NMDS) is a set of essential, uniformly defined nursing data elements developed to make nursing care visible and comparable across settings. This post explains the history and elements of the NMDS, the related Nursing Management Minimum Data Set, how standardized nursing data supports research, quality, and policy, and why it matters in modern EHRs.

The Healthcare Common Procedure Coding System (HCPCS) is the standardized code set used to report procedures, services, drugs, supplies, and equipment on claims, particularly to Medicare. This post explains HCPCS Level I (CPT) and Level II, what Level II codes cover, quarterly updates, modifiers, how HCPCS relates to other code sets, and what it means for nursing documentation.

Digital health is the broad use of digital technologies, including mobile devices, sensors, software, connectivity, AI, and genomic information, to improve health and healthcare. This post explains what digital health includes, how the FDA and WHO approach it, the importance of evidence, integration, and equity, and how nurses help patients and teams use digital tools well.

Capitation is a payment method in which a provider receives a fixed amount per person for a defined period to cover specified services, regardless of how many services each person uses. This post explains how capitation works, types of capitation, risk adjustment, the incentives it creates, the data and health IT it requires, and what it means for nurses.

Abstracting is the process of collecting specific, coded data elements from medical records for reporting, quality measurement, registries, and research. This post explains where abstraction is used, why manual chart abstraction is costly, how structured documentation, electronic measures, and natural language processing reduce the burden, quality controls for abstraction, and nursing roles.

A Veterans Integrated Service Network (VISN) is a regional system of VA medical centers, clinics, and services that work together to meet veterans’ healthcare needs. This post explains how VISNs began, how the VA’s December 2025 reorganization consolidated 18 networks into five, why regional structure matters for standardization, data, and health IT, and what it means for nurses.

The NCPDP SCRIPT standard defines how prescription information is exchanged electronically among prescribers, pharmacies, intermediaries, facilities, and payers. This post explains SCRIPT transactions, from new prescriptions to cancellations and medication history, federal requirements including the move to SCRIPT version 2023011 by 2028, electronic prescribing of controlled substances, and nursing roles.

Radio frequency identification (RFID) uses radio waves to automatically identify and track tagged objects or people without line of sight. This post explains passive and active RFID, how RFID differs from barcodes, real-time location systems, healthcare uses from equipment tracking to infant security and supply management, interference and privacy concerns, and nursing roles.

Middleware is software that sits between applications, translating, routing, and integrating data so systems built on different platforms or by different vendors can work together. This post explains types of middleware in healthcare, from interface engines to device and alarm middleware, why it is essential for interoperability, the risks it introduces, and its impact on nursing workflows.

Identity and access management (IAM) is the set of policies, processes, and technologies that create and manage digital identities and control what each identity can access. This post explains IAM components, from provisioning and authentication to single sign-on and privileged access, why IAM is central to healthcare security, common gaps, and what nurses experience.

A disaster recovery plan (DRP) describes how an organization restores its IT systems and data after a disruptive event such as a fire, flood, power failure, or cyberattack. This post explains how a DRP fits within business continuity planning, the business impact analysis, recovery time and recovery point objectives, protected backups, testing, regulatory requirements, and nursing roles.
