How AWS Powers Bluesight’s Prism to Revolutionize Hospital Pharmacy Compliance
Amazon Web Services (AWS) has provided insights into how Bluesight developed Prism, an innovative AI layer designed to streamline hospital pharmacy operations by integrating compliance data across its product suite. This initiative marks a significant advancement in healthcare technology, promising to mitigate the labor-intensive processes traditionally associated with pharmacy compliance.
The Launch of Prism Assistant for ControlCheck
Prism Assistant for ControlCheck is now generally available and operational across 20 healthcare systems, as reported by AWS. This tool is a part of Bluesight’s mission to enhance efficiency in pharmacy compliance. Meanwhile, a multi-product agent targeting 340B Group Purchasing Organization (GPO) compliance is slated for release in late 2026.
Addressing the Challenges of 340B Compliance
Hospitals often face a daunting task when it comes to evaluating 340B drug purchases. A single covered entity can spend over 4,000 man-hours annually verifying the eligibility of GPO drug purchases for exemptions. This process requires a detailed comparison of purchasing data against U.S. FDA shortage reports, ASHP records, machine learning predictions, and backorder reports.
ControlCheck Agent’s Success in Hospital Systems
Bluesight’s ControlCheck product provides a robust solution for monitoring controlled substances. While it helps diversion teams identify unusual drug transaction patterns, compliance staff traditionally had to manually handle report generation, dashboard reviews, and result correlation. The introduction of Prism Assistant changes this dynamic significantly.
With a conversational interface, Prism Assistant allows users to query ControlCheck data, craft charts, and produce reports efficiently. Developed during a three-day Experience-Based Acceleration session in September 2025, this tool exemplifies the rapid development capabilities facilitated by AWS, though these metrics await validation by participating health systems.
Innovative Technology and Reduced Latency
Utilizing Strands Agents with Amazon Bedrock and hosted via Amazon Bedrock AgentCore Runtime, the development team exposed more than 10 ControlCheck APIs as MCP tools. This approach significantly reduced query latency from five minutes to just 10 seconds, enhancing the overall user experience.
Samir Neyazi, Bluesight’s director of product management, noted that the solution provides diversion program leaders with faster access to answers, eliminating manual investigation efforts. The service was deployed in a virtual private cloud, achieving general availability within nine months.
Advancing 340B Compliance with Multi-agent Systems
The upcoming GPO agent is designed to merge records from CostCheck, ShortageCheck, and 340BCheck. These tools collectively provide purchasing information, evidence of drug availability, and eligibility data, respectively. The architecture leverages Anthropic Claude Sonnet 4.6 for primary operations and Claude Haiku 4.5 for lower latency tasks over Amazon Bedrock.
A unique coordination mechanism allows specialized data workers to retrieve and compile necessary documents for compliance verification, resulting in audit-ready reports. Initial tests on synthetic data indicated a 100 percent invoice recognition rate and 93 percent proof accuracy, but real-world performance remains to be evaluated by hospital systems.
Compliance Assessment and Data Integrity
Bluesight ensures that compliance scoring remains outside the language model, opting for a deterministic scoring service that evaluates evidence and applies rules. This approach provides a transparent, repeatable process, allowing compliance teams to maintain control over policy settings.
Despite automation, teams need to validate historical purchase cases alongside current processes to ensure accuracy, particularly in areas like data completeness and exception handling. Each result includes detailed records of the scoring rules and tool usage.
Security Measures and Audit Trails
AWS ensures HIPAA compliance, with Bluesight operating under a Business Associate Agreement. Encryption and authentication are managed by AWS Key Management Service and Amazon Cognito, respectively. Amazon CloudWatch facilitates comprehensive audit trails, which are crucial for justifying compliance decisions.
Bluesight reports a dramatic reduction in reporting and analysis timeframes, with some workflows experiencing time savings of up to 97 percent. This efficiency allows more timely and accurate compliance decisions.
