Impact of a prototype visualization tool for new information in EHR clinical documents
Applied Clinical Informatics
|May 7, 2013
Summary
A new visualization tool for electronic health records (EHR) shows potential to improve how clinicians synthesize patient information, reducing errors and aiding navigation. Further research is needed to confirm its benefits in clinical workflows.
Area of Science:
- Health Informatics
- Human-Computer Interaction
- Clinical Documentation
Background:
- Electronic Health Record (EHR) clinical document synthesis is often inefficient and error-prone due to complex data structures and inconsistencies.
- Developing adaptable EHR systems requires innovative visualization techniques to optimize information synthesis at the point of care.
Purpose of the Study:
- To assess the impact of a prototype visualization tool on clinicians' synthesis of EHR data.
- To explore how this tool can inform the design of future clinical document user interfaces.
Main Methods:
- A mixed-methods approach was employed.
- Eight medical interns participated, synthesizing EHR documents for four clinical scenarios using a think-aloud protocol.
Main Results:
- While not statistically significant, the visualization tool showed a trend towards reducing missing patient information (2.3 vs. 6.8) and improving accurate inferences (1.3 vs. 2.3).
- Task completion times did not differ significantly overall, but were shorter in two scenarios with the tool.
- The tool facilitated more intuitive navigation and encouraged methodical document synthesis.
Conclusions:
- New information visualization in clinical notes may enhance the synthesis of patient information from EHRs.
- Findings support the development of advanced visualization applications for more effective EHR display.

01:21Methods of Documentation III: PIE
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:
01:30Methods of Documentation VII: EMR
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare settings,...
01:28Formats for Nursing Documentation
Nursing documentation encompasses various formats designed to capture precise patient data, facilitate communication among healthcare team members, and ensure comprehensive and accurate patient records. Let's explore each of these formats in detail:
Nursing Assessment Form:
• A nursing assessment form is a foundational document that captures detailed patient data from physical assessments and nursing histories.
• It includes patient demographics, medical history, current medications, vital...

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:

01:23Methods of Documentation V: CBE
Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...

01:15Methods of Documentation VI: Case Management Model
The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
