Pressure Ulcer Classification System Using Hierarchical Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for classifying pressure ulcers lack accuracy and efficiency, often leading to incorrect staging and inappropriate treatment, due to the complexity of diagnosing and the lack of effective tools to assist healthcare providers.
Innovation Solution
A pressure ulcer diagnostic (PUD) clinical decision support system that systematically determines if a wound is caused by pressure, and if it has been classified as a Stage 4, then systematically rules out other classifications in a hierarchical approach to ensure accurate diagnosis and prevent reverse staging, using a data store and processor to analyze digital images and symptoms for precise classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If healthcare providers use manual assessment methods to classify pressure ulcers, then they can physically examine the wound and review medical records, but the classification accuracy is low and mistakes such as reverse staging occur frequently
Solution Approach 1:
The patent introduces a computer-based pressure ulcer classification system that acts as an intermediary between the healthcare provider and the classification decision. The system includes a processor that receives wound images and medical record data, applies classification algorithms, and generates recommended classifications. This intermediary computational system reduces human error and subjectivity while maintaining the clinical assessment process.
Solution Approach 2:
The patent replaces the manual mechanical assessment process with an automated computational system. Instead of relying solely on human visual inspection and subjective judgment, the system uses image processing algorithms, data analysis, and automated classification logic to determine pressure ulcer stage, thereby improving consistency and reducing mistakes like reverse staging.
2Adaptability or versatility
If healthcare providers undergo extensive training to accurately stage pressure ulcers, then they gain clinical knowledge, but even experts do not stage pressure ulcers accurately all of the time
Solution Approach 1:
The system enables self-service classification by providing healthcare providers with an automated tool that performs the complex classification analysis. The processor automatically analyzes wound images, compares them against classification criteria, and generates staging recommendations, reducing the burden on providers while improving accuracy. The system serves itself by having the algorithm continuously refine classifications based on input data.
3Ease of operation
If no automated tools are used for pressure ulcer classification, then the process remains simple and direct, but effective tools to assist providers with classifying pressure ulcers do not exist
Solution Approach 1:
The system performs preliminary classification analysis by automatically processing wound images and medical record data before the provider makes the final determination. The processor pre-analyzes the data, identifies key features, and generates recommended classifications, thereby preparing the information in advance and improving overall classification efficiency without adding complexity to the provider's workflow.
4Ease of operation
If manual classification methods are used, then healthcare providers can assess wounds directly, but reverse staging occurs where the severity is incorrectly reduced
Solution Approach 1:
The system incorporates feedback mechanisms where the processor continuously monitors classification decisions, compares them against established criteria, and provides alerts or corrections when potential reverse staging is detected. The system feeds back classification recommendations to the provider, allowing verification and correction before finalizing the staging, thereby preventing erroneous downgrading of ulcer severity.

AI summary
Systems and methods for accurately and efficiently diagnosing, assessing, staging/grading/categorizing, and treating pressure ulcers, as well as preventing reverse staging of pressure ulcers, are disclosed. The system, in one embodiment, ensures that the rationale for the stage assigned to the patient will be in the patients' medical record. The system, in various embodiments, further suggests the pressure ulcer classification and allows the user to choose which classification terms should be used. In various embodiments, the system also allows for the different classification/staging system guidelines to be used, including the National Pressure Ulcer Advisory Panel (NPUAP) guidelines, the European Pressure Ulcer Advisory Panel Guidelines (EPUAP), the Pan Pacific Pressure Injury Alliance, CMS, WHO, and the MDS Guidelines.
