Core Concepts
The CAPABLE system employs a hybrid execution environment for computer-interpretable guidelines (CIGs) represented in the PROforma formalism, which extends a standard PROforma execution engine with specialized components to handle non-standard tasks and facilitate integration with the overall system.
Abstract
The CAPABLE system aims to provide coaching for cancer patients treated at home and clinical decision support for their physicians. It relies on data- and knowledge-driven models, including computer-interpretable guidelines (CIGs) represented using the PROforma formalism.
The system employs a hybrid execution environment that extends the standard Deontics Engine (DE) PROforma execution engine with the following specialized components:
Physician Decision Support System (PDSS)
Virtual Coach (VC)
Goal-Oriented Comorbidities Controller (GoCom)
These components act as wrappers around DE, allowing them to handle non-standard tasks and mediate access to a shared, FHIR-based data repository. The hybrid environment also utilizes an extensive set of custom meta-properties associated with PROforma data items and tasks to facilitate the mapping of patient data among multiple components and processes, optimize the interactions between the components, and address challenges related to CIG execution, non-standard task handling, and conflict mitigation between proposed and prescribed pharmacological treatments.
The operational cycles of PDSS and VC are presented, demonstrating how they rely on the core functionality provided by DE while also invoking specialized components and data sources to handle their specific requirements.
