View Messages →Core Services
The Link platform is built on a suite of core services that work together to automate reporting workflows, from data acquisition through to submission.
- Platform agnostic: using interfaces for specific implementations such as Azure.
- Micro services: for scalability in cloud environments.
- Event driven: service interaction (where appropriate) using Kafka.
Data Acquisition Service
Responsible for retrieving raw data from external facility systems and initiating the processing pipeline.
Census Service
Manages patient population data and scoping for reporting periods and facilities.
Normalization Service
Transforms varied facility data formats into a standardized, internal format suitable for evaluation.
Measure Evaluation Service
Executes business logic and clinical quality measures against normalized data to calculate metrics.
Validation Service
Ensures that generated reports and data packages comply with NHSN standards and internal policies.
Submission Service
Handles the secure transmission of validated data and reports to external stakeholders and agencies.
Admin UI (front-end)
Web-based user interface for managing users, measures, validation profiles, terminology, tenants and reports.
Primary Use Cases
NHSN Reporting
Our primary use case involves the automated generation and submission of healthcare-associated infection reports to the National Healthcare Safety Network (NHSN). This workflow utilizes the entire Link stack to increase reporting reliability and reduce the administrative burden on facilities by submitting granular, patient-level data directly to NHSN.
