𝗧𝗵𝗲 𝗾𝘂𝗲𝘀𝘁𝗶𝗼𝗻 𝗵𝗲𝗮𝗹𝘁𝗵𝗰𝗮𝗿𝗲 𝗔𝗜 𝘁𝗲𝗮𝗺𝘀 𝗮𝗿𝗲 𝗮𝘀𝗸𝗶𝗻𝗴 𝗶𝗻 𝟮𝟬𝟮𝟲 𝗶𝘀𝗻'𝘁 "𝗖𝗮𝗻 𝘄𝗲 𝗯𝘂𝗶𝗹𝗱 𝗮𝗻 𝗮𝗴𝗲𝗻𝘁?" 𝗜𝘁'𝘀 "𝗛𝗼𝘄 𝗱𝗼 𝘄𝗲 𝗸𝗻𝗼𝘄 𝗶𝘁'𝘀 𝘀𝗮𝗳𝗲 𝗳𝗼𝗿 𝗽𝗮𝘁𝗶𝗲𝗻𝘁𝘀?"

Too many agents are deployed before they’re ready, leading to incidents that set automation back by years. Here is the framework for true operational readiness:
• 𝗕𝗲𝗻𝗰𝗵𝗺𝗮𝗿𝗸𝘀 𝘃𝘀. 𝗥𝗲𝗮𝗹𝗶𝘁𝘆: A 90% accuracy score on a clinical Q&A benchmark does not predict success with complex, multi-step transactions such as prior authorization.
• 𝗜𝗱𝗲𝗻𝘁𝗶𝗳𝘆 𝗙𝗮𝗶𝗹𝘂𝗿𝗲 𝗠𝗼𝗱𝗲𝘀: You must evaluate agents against systemic risks, including reasoning vulnerabilities, tool integration latencies, and escalation anomalies.
• 𝗦𝗶𝗺𝘂𝗹𝗮𝘁𝗶𝗼𝗻 𝗼𝘃𝗲𝗿 𝗗𝗲𝗺𝗼𝘀: Stop relying on "happy path" vendor demos. Implement rigorous workflow simulations that test administrative edge cases, state persistence, and live integrations.
• 𝗖𝗼𝗻𝘁𝗶𝗻𝘂𝗼𝘂𝘀 𝗚𝗼𝘃𝗲𝗿𝗻𝗮𝗻𝗰𝗲: Deployment is only the beginning. You must continuously monitor for environmental degradation, including regulatory shifts, model drift, and shifting patient cohort distributions.

The "deploy-and-observe" era must end. Healthcare enterprises require a verifiable, reproducible foundation for risk mitigation to ensure compliance and patient safety.

Frameworks like actAVA KORA and χ-BENCH provide the structure necessary to move from perpetual pilot to production-ready automation.

We welcome Tom Patterson to the actAVA AI advisory board.

As the SVP of Corporate Development and Strategy at BetterUp and a 3-time founder, Tom brings deep operational expertise in aligning enterprise technology with human performance and workforce resilience.
In this role, Tom advises us on integrating human-in-the-loop safeguards into the agent lifecycle.

His focus centers on critical governance infrastructure, including:
- Privacy Compliance: Structuring models to strictly adhere to enterprise privacy regulations.
- User Agency: Implementing clear design frameworks that distinguish AI-generated advice from human guidance.
- Workforce Stability: Deploying systems capable of monitoring operational distress cues to support frontline teams.

Tom’s first question to us was “How do you scale production-ready agentic AI without introducing workforce instability or employee anxiety?” From Tom’s point of view, technology can only move from pilot to production when built with rigid structural safeguards that protect the human element. Building an unshakeable partnership between silicon and carbon requires evidence-led governance, not open-ended promises. We agree!

We are grateful for Tom’s partnership as we continue to build the infrastructure for responsible, governed, and measurable agentic AI at enterprise scale.

🚀 @claudeai Opus 4.8 just took #1 on CHI-Bench (long-horizon healthcare agents).

75 real workflows across prior auth, utilization & care management.

Opus 4.8 → 33.3% (PA 32 · UM 28 · CM 40)
Opus 4.6 → 28.0% (PA 18 · UM 41 · CM 24)
Opus 4.7 → 24.4% (PA 24 · UM 17 · CM 32)

Agents like Claude Code, Codex can sustain hundreds of tool calls and ace coding. So we had 30 of them run a real prior-auth, utilization management and care management case end to end. Best agent still fails 72% of U.S. healthcare workflows

In real healthcare operations, agents must do far more than answer medical questions. They need to read charts, interpret clinical and operational policies, verify coverage, route referrals, draft P2P scripts, and finalize care plans — where a single policy violation can mean a denied claim or missed patient outcome.

@actAVAai @iscreamnearby led and developed CHI-Bench (Clinical Healthcare In-situ Benchmark), the first long-horizon, policy-rich benchmark for AI agents operating across end-to-end U.S. healthcare workflows.

Key highlights:

▶️ High-fidelity simulators for Provider Prior Authorization, Payer Utilization Management, and Population Health Care Management, all exposed as MCP servers over patient, clinician, and insurer records.

🧪 Each trial runs 60–80 agent steps across 4–6 clinical stages, with access to 21 healthcare apps, 200+ MCP tools, and a 1,279-document operations handbook.

Leaderboard results across 30 frontier agents:
• Claude Code + Opus 4.6: 28% pass@1
• Codex + GPT-5.5: 21%
• Utilization review: 41%
• Care management: 32%
• Prior authorization: 29%
Reliability remains a major challenge: no agent exceeds 20% when the same case is repeated three times.

(1/n) After a few months of work with multiple hospitals, universities and research facilities, today we're open-sourcing CHI-Bench: the first long-horizon benchmark for healthcare AI agents on real clinical and healthcare workflows.

Best frontier agent overall: 28% pass@1.
End-to-end prior authorization: 0%.

1/ Introducing CHI-Bench 🧵

Can AI agents automate U.S. healthcare workflows end to end — given only clinician & insurer apps, operations, and a medical policy library?

75 long-horizon workflows × 30 frontier agents. Best agent solves just 28%.
