Two artificial intelligence approaches accurately identified patients with MRI safety-risk implantable devices. Both expert-driven and ontology-driven natural language processing (NLP) methods showed comparable performance in clinical data analysis.
Area of Science:
- Medical Informatics
- Artificial Intelligence in Healthcare
- Clinical Data Analysis
Background:
- Identifying patients with implantable devices posing MRI safety risks is crucial for patient care.
- Existing methods for identifying these devices may be time-consuming or incomplete.
- Natural Language Processing (NLP) offers potential for automated identification.
Purpose of the Study:
- To compare the accuracy of expert-derived and ontology-derived NLP approaches for identifying patients with MRI-unsafe implantable devices.
- To determine the prevalence of such devices within various clinical data sources.
Main Methods:
- Retrospective study at an academic hospital comparing two NLP methods: expert-derived and ontology-derived.
- Expert-derived approach used curated terms; ontology-derived approach used Systematized Nomenclature of Medicine-Clinical Terms.
- Analysis of radiology reports, emergency department notes, and other clinical reports.
Main Results:
- Both expert-derived and ontology-derived NLP approaches demonstrated similar accuracy, sensitivity, and specificity.
- The proportion of clinical reports identifying high-risk implantable devices ranged from 1.47% to 1.88%.
Conclusions:
- Artificial intelligence, specifically expert-driven and ontology-driven NLP, are effective and comparable tools for identifying patients with MRI safety-risk implantable devices.
- These NLP methods can be integrated into clinical workflows to enhance patient safety.

Introduction to Documentation and Reporting
Nursing documentation records essential information and details regarding a patient's care and treatment in written or electronic form. It is a critical aspect of nursing practice that involves documenting assessments, interventions, outcomes, and other relevant details about a patient's health status.
Documentation maps the patient's health journey by creating a comprehensive...
Retrieval
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...
