Generic Clinical Decision Support Architecture

Effective clinical decisions are dependent on the availability of complete and accurate patient information. Historically, gathering medical information has been cumbersome, requiring practitioners to manually retrieve individual data elements from multiple sources. Practitioners rely on clinical experience and judgment to fill information gaps, leading to inconsistent care practices that do not allow guidelines based on evidence to emerge.

Increasing availability of patient data through interoperable medical devices presents the opportunity to better inform clinical decisions at the point of care and reduce caregiver workload. Improved availability of data also provides the foundation for evaluating outcomes of specific interventions and fosters the development of evidence based guidelines for providing consistent care. Clinical decision support systems, systems that gather, analyze, and present patient information to caregivers to help them make better decisions, represent an important component for delivering evidence based medicine that could substantially improve patient care.

G-CDSA is a generic architectural framework designed to facilitate the design and implementation of clinical decision support systems. The framework is modular, to promote rapid prototyping, isolation, and reuse of common components.
