Microbiota Activity Sensor for Clinical Decision Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies lack the ability to effectively utilize changes or trends in gut microbiota compositional states for health characterization, prognosis, and treatment effectiveness, leading to inadequate decision support in healthcare.
Innovation Solution
A decision support tool that determines microbiota diversity and relative abundances in patient specimens, assesses statistically significant changes or trends, and initiates appropriate interventions, such as notifications or care plan modifications, using methods like rarefaction, 16S rRNA sequencing, and multivariate analysis of variance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional technology is used to measure microbiota, then basic compositional data can be obtained, but the ability to effectively utilize changes or trends in microbiota compositional states for health characterization, prognosis, and treatment effectiveness is insufficient
Solution Approach 1:
The system performs preliminary actions by establishing baseline microbiota compositional states and monitoring frameworks before clinical decisions are made. It proactively tracks temporal patterns and prepares statistical models in advance, enabling earlier intervention and more reliable decision support when changes are detected
Solution Approach 2:
The system implements continuous feedback loops by monitoring microbiota compositional changes over time and using this information to adjust and improve decision support reliability. Statistical significance testing and trend analysis provide feedback on whether observed changes are meaningful, allowing the system to refine its predictions and recommendations
2Reliability
If comprehensive microbiota monitoring is implemented to identify emerging health conditions, then early detection capability is improved, but system complexity increases
Solution Approach 1:
The system extracts and focuses on specific, clinically relevant microbial taxa and compositional features from complex microbiota data. By identifying and monitoring only the most significant indicators of health conditions, it reduces the complexity of the monitoring system while maintaining high early detection capability
Solution Approach 2:
The system transforms complex microbiota compositional data into simplified statistical parameters and trends that are easier to analyze and interpret. By changing the representation from raw compositional data to statistical significance metrics and temporal patterns, it reduces system complexity while improving detection reliability

AI summary
An improved decision support tool is provided for detecting, diagnosing, or treating human patient based on detected changes or trends in microbiota-related activity of the patient. The decision support tool determine a longitudinal pattern of relative abundances or diversity levels of microbiota, and subsequently determine the occurrence of alternations or trends, which may indicate or be related to meaningful clinical events, such as a change in condition for the patient. In one embodiment, a joint determination of statistical significance of change and trend is first detected and then utilized to determine an occurrence of clinically meaningful microbiota activity in a patient. The decision support tool may further initiate an intervening action based on a detected change or trend, such as generating an electronic notification, modifying a treatment program, providing a recommendation, automatically allocating health care resources to the patient, or automatically scheduling a consultation with a caregiver.
