Longitudinal Electronic Medical Record System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current healthcare patient record standards, such as CCR, HL7 RIM, and HL7 CDA, fail to address the need for longitudinal patient medical record structures, primarily focusing on snapshot data rather than continuous patient information over time, which limits their effectiveness in managing and organizing patient data for day-to-day care.
Innovation Solution
A system and method for capturing and managing longitudinal electronic medical records (LEMR) that includes generating data objects with temporal identifiers, linking them to summarize references, and tracking relationships between data objects over time, while ensuring compliance with HIPAA and supporting secure data exchange and privacy protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If snapshot-based record standards (CCR, HL7 CDA) are used, then data exchange is enabled, but longitudinal patient information continuity is lost
Solution Approach 1:
The patent applies preliminary action by pre-defining a longitudinal record structure framework that anticipates future data needs. The system establishes a persistent patient record architecture before data entry, with pre-configured relationships between data objects, temporal identifiers, and summarization references. This allows the system to automatically maintain continuity over time without requiring complex post-processing or restructuring.
2Reliability
If detailed data objects are tracked over time, then patient continuity is improved, but system complexity increases
Solution Approach 1:
The patent implements the nested doll principle by creating hierarchical data structures where data objects are nested within encounters, which are nested within patient records. Summarization references act as containers that group related data objects across multiple encounters. This nesting approach organizes complex longitudinal data into manageable hierarchical levels, reducing system complexity while maintaining data continuity and reliability.
3Productivity
If temporal identifiers and relationships are implemented, then data organization over time is improved, but processing requirements increase
Solution Approach 1:
The patent applies the copying principle by creating lightweight summarization references that capture essential temporal relationships without duplicating entire data objects. Instead of copying and storing complete data sets for each encounter, the system creates reference pointers to original data objects, maintaining temporal relationships through identifier links. This reduces computational processing requirements while improving data organization efficiency over time.
Data Source
AI summary
A method of implementing a controlled vocabulary may include the steps of generating the controlled vocabulary by forming a list of medical terms and associated descriptions; creating a list of codes internal to the controlled vocabulary; and storing the codes, the medical terms, and the descriptions in a format suitable for use in the patient longitudinal electronic medical record environment. In addition, a sound wave may be captured as an electronic file, translated into text, and stored as a patient medical record event. The patient medical record event may be parsed for context and may be tagged with one or more source vocabularies, and a code internal to the source vocabulary may be provided. Event context and source vocabulary findings may then be used as discrete elements to add to the longitudinal patient electronic medical record environment.
