The ControlCheck Prism Assistant is now generally available across 20 health systems, AI News reported, citing AWS vendor statements about Bluesight’s hospital compliance AI work.

The same public account said a separate multi-product agent for 340B Group Purchasing Organisation compliance remains scheduled for later in 2026.

AWS described the project as part of hospital pharmacy and compliance workflows rather than a general chatbot rollout.

AWS said one covered entity in the 340B programme can spend more than 4,000 staff hours a year checking whether GPO drug purchases qualify for an exception, using shortage notices, pharmacy records, inventory data, machine-learning forecasts and back-order reports.

Prism Assistant Runs Across 20 Health Systems

Bluesight built Prism Assistant for ControlCheck, its controlled-substance monitoring product.

AI News reported that hospital diversion teams use ControlCheck to identify unusual medication transaction patterns, while compliance staff previously assembled reports, reviewed dashboards and matched findings manually.

Prism Assistant gives users a conversational interface for ControlCheck data, chart creation and report material.

According to AWS, the first build came from a September 2025 Experience-Based Acceleration engagement with eight Bluesight engineers, seven AWS specialists and a three-day timetable.

The production deployment uses Strands Agents with Amazon Bedrock and is hosted through Amazon Bedrock AgentCore Runtime.

AWS said AgentCore Gateway exposes more than 10 ControlCheck APIs as MCP tools, allowing the agent to find and call approved product functions during a user request.

AWS Lists Bedrock AgentCore And MCP Tooling

Bluesight did not give the language model direct database access.

The company wrapped existing ControlCheck API endpoints in AWS Lambda functions that return structured data for agent processing, while business logic stays inside the application layer.

AWS reported that the design cut query latency from five minutes to 10 seconds.

The deployment also includes chart generation, observability controls, cost attribution, encryption, authentication and infrastructure-as-code, according to the AI News account.

Samir Neyazi, Bluesight’s director of product management, said the tool gets diversion programme leaders to answers faster and removes manual work from investigations.

AWS said the service reached general availability in under nine months, while the 20 health systems represent the active deployment evidence disclosed in the AI News account.

340B GPO Agent Remains Scheduled For 2026

The planned GPO agent is narrower and more regulated.

Federal 340B rules prohibit certain hospitals from using GPO contracts for outpatient drugs when non-GPO channels can supply the drug, and compliance teams must document exceptions when supply conditions block that route.

Bluesight’s planned system brings together CostCheck purchase records, ShortageCheck drug-availability evidence and 340BCheck eligibility data.

The architecture uses Anthropic Claude Sonnet 4.6 as the main model and Claude Haiku 4.5 for lower-latency operations through Amazon Bedrock.

A coordinating GPO agent assigns work to specialist data agents for purchase records, supply evidence and 340B eligibility.

AWS said a March 2026 acceleration engagement connected the system by the end of its first day and completed planned features by the end of day two.

Synthetic Tests Stop Short Of Hospital Production Evidence

AWS said synthetic testing produced a 100 percent invoice discovery rate and 93 percent evidence justification accuracy, above an 85 percent target.

AI News cautioned that those figures do not represent production performance across hospital customers.

The test record described prepared scenarios, not local data gaps, delayed shortage updates, unusual drug identifiers or disputed purchasing cases.

Bluesight assigns the language model a constrained role: it gathers records, calls product tools and drafts the explanation, while a deterministic scoring service calculates the compliance determination.

AWS said the deterministic scoring layer uses 13 evidence inputs, priority matching and configurable time windows.

Hospital pharmacy, legal and compliance teams remain responsible for policy settings such as shortage thresholds, inventory periods and purchase-date windows.

AWS And Bluesight List HIPAA And Audit Controls

AWS listed HIPAA eligibility for Amazon Bedrock and said Bluesight operates under a Business Associate Agreement with the cloud provider.

AWS said it does not train foundation models on customer data processed through Amazon Bedrock.

The deployment uses Amazon Cognito for OAuth2 client-credential authentication and JSON Web Token validation.

AWS said AgentCore Runtime isolates concurrent customer sessions, Key Management Service encrypts data at rest and in transit, and Secrets Manager handles downstream credentials.

CloudWatch records agent decisions, tool invocations, data-access events, alarms and performance metrics.

Bluesight’s internal measurements across 20 health systems reported up to 97 percent faster report generation and analysis in ControlCheck workflows, including recurring reports moving from about six hours of manual assembly to 15 minutes.

AWS and Bluesight did not name the 20 health systems, disclose customer pricing, publish hospital-level production performance for the GPO agent, or give a launch date beyond later in 2026.
