Summary
Specialized medical knowledge is crucial for designing effective electronic health record (EHR) templates. Different medical specialties require distinct data elements for accurate patient care, highlighting the need for physician involvement in EHR design.
Area of Science:
- Clinical Informatics
- Health Information Technology
- Medical Education
Background:
- Structured templated notes in Electronic Health Records (EHRs) aim to standardize clinical documentation.
- The design of these templates often overlooks the specialized knowledge of different medical domains.
- This can lead to inefficiencies and potential gaps in patient data collection.
Purpose of the Study:
- To evaluate the impact of specialized domain knowledge on the design and utility of structured templated notes in clinical settings.
- To underscore the importance of involving domain experts in EHR template development.
Main Methods:
- Compared templated History of Present Illness (HPI) notes for dermatology vs. emergency department (ED) patients.
- Analyzed chest pain evaluations by ED physicians vs. cardiologists.
- Examined gastrointestinal system evaluations by cardiologists vs. liver transplant service (LTS).
- Utilized SNOMED CT via BioPortal to assess data element specificity and grouping.
Main Results:
- Found minimal overlap in structured data elements between different medical specialties.
- Observed significant differences in data element granularity and fundamental requirements.
- Dermatologists requested more granular elements than ED physicians; cardiologists requested highly granular data.
- Cardiologists and LTS differed in their requested data elements.
Conclusions:
- Domain knowledge is essential for effective EHR design and implementation.
- Cognitive science supports that different specialties naturally require and utilize distinct information.
- Physician involvement with appropriate domain expertise is critical for designing functional templated notes.

01:30Impact of Schemas
319
Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

Focus Charting, also known as the focus charting system or "focus documentation," is a systematic documentation approach used in healthcare to organize patient information in medical records.
It typically involves three columns for recording information:

01:08Data Collection by Observations
11.0K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.

01:18Methods of Documentation I: Source-Oriented Records
1.6K
Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:

Problem-intervention-evaluation (PIE) is a systematic approach to documentation used in healthcare settings for clinical decision-making and patient care planning. It is a structured approach to organizing patient data based on problems, interventions, and evaluations. Here's a breakdown of its key features and considerations:

01:22Design Consideration
681
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
