Perspectives on Healthcare IT, clinical informatics, emerging technology, and life at the intersection of nursing and enterprise systems.
Computerized Provider Order Entry replaced the handwritten order and the transcription step that came with it. This post explains what CPOE is, how it differs from CDSS and e-prescribing, what the safety evidence shows, and how it changed nursing workflow and Go-Live work.
Artificial Intelligence in healthcare is not a single technology; it is a family of techniques — rule-based systems, machine learning, natural language processing, and generative AI — each with distinct capabilities, risks, and governance requirements. This post breaks down the four categories, the ONC HTI-1 transparency rule, the FDA framework, and how AI shows up at the bedside and on the CAHIMS exam.
EHR usability is not just a design consideration; it is a regulatory concern, a workforce retention issue, and a measurable patient safety factor. This post breaks down the five dimensions of usability, why nurses feel the cost most acutely, and how it shows up on the CAHIMS exam.
Telehealth spent two decades as a niche capability, then became permanent healthcare infrastructure almost overnight. This post breaks down the four telehealth modalities, why telehealth is not the same as telemedicine, how it reshaped nursing practice, and how it shows up on the CAHIMS exam.
Protected Health Information is the operational unit of HIPAA — the specific category of data every rule, safeguard, and breach notification exists to protect. This post breaks down what PHI is, the 18 identifier categories, how PHI differs from ePHI and IIHI, and how it shows up at the bedside and on the CAHIMS exam.
Meaningful Use is the single biggest reason American hospitals digitized when they did. Billions in incentive payments — and later, penalties — moved EHR adoption from a minority practice to near-universal in under a decade. This post breaks down the HITECH origin, the three MU stages, the 2018 rename to Promoting Interoperability, and how it shows up at the bedside and on the CAHIMS exam.
Data governance is the unglamorous, absolutely foundational discipline under every analytics, interoperability, and AI initiative in healthcare. This post breaks down what data governance is, how it differs from stewardship and integrity, and how it shows up in nursing workflows and on the CAHIMS exam.
A Clinical Decision Support System is where the EHR stops being a filing cabinet and starts behaving like a clinical colleague. This post breaks down how CDSS works, why alert fatigue is its dominant failure mode, how it shows up in nursing workflow, and how to handle it on the CAHIMS exam
The ACO model is one of the most consequential operational structures in modern U.S. healthcare — and one of the most demanding for health IT. This post breaks down what an ACO is, why it depends entirely on informatics, and how it shows up at the bedside and on the CAHIMS exam.
