Offline Portal Proxy for Clinical Trial Data Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clinical trial operations systems face challenges in allowing web and mobile device applications to function offline due to lack of network connectivity, necessitating an offline mode capability for continuous user interaction and data collection.
Innovation Solution
A mobile-native clinical trial operations service suite is enhanced with offline mode capabilities, including a synchronization service that allows data collection offline and subsequent synchronization when connectivity is restored, along with offline portal proxies and data caches for patient and clinician applications, enabling continued operation and secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If web and mobile device applications interact with the service suite via network connection, then real-time data synchronization and communication are achieved, but the applications cannot function when network connectivity is unavailable
Solution Approach 1:
The system performs preliminary actions by providing applications with a copy of workflows and screens in advance while connected to the network. This cached data enables the applications to function offline without real-time network connectivity, resolving the contradiction between requiring network connection for functionality and needing to operate when connectivity is unavailable.
2Productivity
If the service suite is made fully automated for clinical trial operations, then efficiency and data collection speed improve, but the system becomes more complex and requires continuous network connectivity
Solution Approach 1:
The system segments functionality by separating online and offline modes, with the offline portal proxy handling local operations and the synchronization service managing data transfer when connected. This segmentation allows automated data collection to proceed offline while maintaining the ability to synchronize with the central service suite, reducing the complexity burden of continuous network connectivity requirements.
3Reliability
If continuous network connectivity is required for data synchronization, then data integrity is maintained, but user experience deteriorates when connectivity is lost
Solution Approach 1:
The offline portal proxy acts as an intermediary between the application and the service suite. It maintains data integrity by caching workflows and screens locally, then synchronizes this data with the central service suite when network connectivity is restored. This intermediary approach preserves data integrity while improving user experience by allowing continuous operation during connectivity loss.

AI summary
A trial operations service suite system and method in a clinical trial operations system with a patient portal providing patient-directed access to clinical trial operation services, a clinician portal providing clinician-directed access to the clinical trial operation service, and a coordinator portal providing coordinator-directed access to the clinical trial operation services, the coordinator portal also providing access to a trial design service wherein the trial design service is configured to allow a coordinator user to at least one of design, create, establish, and deploy a trial protocol and a participant interaction procedure, and a synchronization capability, synchronizing when online, information collected while a portal-supporting application is offline.
