Solution Overview
Problem
Clinical studies face challenges in ensuring compliance with protocols due to human errors and inefficiencies in monitoring, leading to suboptimal success rates and inaccurate site performance evaluations, particularly in multi-site global studies.
Innovation Solution
A system and method that utilizes data from a group of devices to detect compliance issues in real-time by aligning events and determining individual and group compliance scores, enabling real-time correction and reducing human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual monitoring methods are used to track compliance in clinical studies, then human oversight can identify issues, but the process is time-consuming and reduces productivity
Solution Approach 1:
The patent replaces manual mechanical monitoring processes with an automated electronic system that collects data from multiple devices, aligns events temporally, and calculates compliance scores automatically. This substitution eliminates human labor in compliance tracking while maintaining or improving detection accuracy through systematic data analysis.
Solution Approach 2:
The system enables self-monitoring of compliance by automatically collecting data from devices used by study participants and clinicians, processing this data through event alignment, and generating compliance scores without requiring external manual review. The system serves itself by autonomously identifying and reporting compliance issues.
2Reliability
If extensive human resources are allocated to monitor compliance across multiple sites, then compliance issues can be detected, but resource expenditure increases significantly
Solution Approach 1:
The patent creates a universal compliance monitoring system that can be deployed across multiple clinical study sites simultaneously. The same electronic infrastructure and algorithms serve all sites, eliminating the need for separate manual monitoring teams at each location. The system performs multiple functions including data collection, event alignment, compliance scoring, and reporting through a single integrated platform.
Solution Approach 2:
The system uses electronic copies of data from various devices (wearables, EDC systems, site management systems) to assess compliance, replacing the need for physical human review of original records. These digital copies can be processed automatically and replicated across sites without additional resource costs.
3Loss of time
If real-time compliance monitoring is implemented, then compliance issues can be identified promptly, but system complexity increases
Solution Approach 1:
The system performs preliminary event alignment and data synchronization before compliance analysis. By pre-processing data from multiple sources and establishing temporal relationships in advance, the system reduces the complexity of real-time analysis. The event alignment framework is prepared beforehand, allowing rapid compliance scoring when data arrives.
Solution Approach 2:
The patent introduces an intermediary event alignment layer that mediates between raw device data and compliance evaluation. This intermediary process standardizes and synchronizes events from different sources before they are analyzed for compliance, simplifying the overall system architecture by creating a uniform intermediate representation that is easier to process.
4Device complexity
If traditional compliance monitoring methods are used, then implementation is simpler, but measurement precision of compliance scores is insufficient
Solution Approach 1:
The system changes the parameters used to measure compliance from simple binary checks to multi-dimensional event alignment metrics. By analyzing temporal relationships, event sequences, and synchronization across multiple devices, the system generates more precise compliance scores that reflect actual adherence behavior more accurately than traditional methods.
Data Source
AI summary
A method includes, for each user of a group of users participating in a first clinical study: collecting a plurality of data associated with the user, wherein the plurality of data includes data received from a group of devices used by the user over a duration during the first clinical study; determining a state related to the user based on the plurality of data, wherein the state indicates operating conditions of the group of devices used by the user; determining an event alignment status by aligning events logged by the group of devices based on the state related to the user; and determining an individual compliance score for the user based on the event alignment status. The method also includes providing a recommended duration of the first clinical study based on the individual compliance scores of the group of users.
