The PICASO platform is a service oriented, cloud-based integration platform based on an orchestration of personalised care services defined by clinicians. The method for sharing patient information between all relevant formal and informal care providers is using a trust-federated solution, which overcomes the problem of data privacy in cloud-based health systems. The main innovations of the project are:
CARE MANAGEMENT AS A SERVICE
PICASO offers a comprehensive cloud solution enabling care organisations to benefit from scalability and software resource sharing without violating regulations on clinical data.
All software for care management and decision support is hosted in one public cloud while all clinical data reside inside the care organisations.
All access and use of clinical data are done in a secure and authorised way, without violating privacy of personal data in accordance with the General Data Protection Regulation (GDPR).
PATIENT SELF-MONITORING AS A SERVICE
The Patient Self-Monitoring Solution is supported by the Patient Dashboard and the PICASO App. Unlike existing solutions, this service integrates all three types of monitoring schemes:
• Scheduled vital signs measurements with medical devices
• Continuous activity and behaviour monitoring using wearable sensors
• Patient self-assessment and medication recording.
All patient measurements are transferred in a secure way into the designated storage facility. This helps patients and clinicians to establish a complete view of vital health parameters and their fluctuations over time.
It also enables care organisations to take advantage of standardised off-the-shelf products for health to improve therapy of patients with multimorbidities.
REFERENCE DATA SERVER
Built on the international standard HL7 FHIR® (Fast Healthcare Interoperability Resources), the server enables interoperability between different data sources coming from different health providers. It uses a scalable NoSQL database that supports data analytics and clustering and offers a standard REST interface, supporting extended functionality for different target groups.
Within PICASO it is used to store standard and customised code systems and value sets, medications and templates that support the creation of services for patient care plans.
RISK MANAGER
The Risk Manager provides patient-specific risk estimates, merging standard charts with novel risk scores into one single tool. These risk scores use machine learning to merge data from a patient’s entire history into a single integrated risk score, including the effect of comorbidities as well as genetic, social and behavioural data.
An integrated simulation tool enables the clinician to explore with the patient what life-style changes will most likely improve the outcome.
DATA RESOURCE BROWSER AND PATIENT DATA VIEWER
Clinicians can browse all available patient data in the Data Resource Browser. Searching for relevant patient data is intuitive and quick with information being updated when the user clicks on the different items. The Patient Data Viewer gives the user a full overview of existing patient data in the system, including data received by other clinicians. Access to read specific patient data, such as measurements, intervention and care plans, requires authorisation.
DISTRIBUTED VALIDATION AUTHORITY - DIVA
DIVA ensures that data are only shared if all policies and transaction specific privacy and security requirements are met. DIVA combines an Access Manager, Identity Manager and Policy Manager, which ensure the following:
• A secure connection to the PICASO Public Cloud as well as communication between Public and Local Clouds
• Identification and authentication of users
• Verification of data transactions as valid and compliant.
