Healthcare transactions need new AI expertise. Sheppard Mullin's webinar on October 28th addresses how the FDA views AI as a major disruptor across trials, diagnostics, and oversight. The regulator demands transparency, validation, and ongoing monitoring. Review capacity is strained, causing longer timelines. Buyers must verify model validation records, trace data provenance, review vendor contracts for IP and liability, and budget for extended regulatory reviews. AI artifacts are now core deal items, not afterthoughts.

PCI Navigator from HeartFlow uses AI to help cardiologists plan interventions before entering the lab. This planning tool maps procedures ahead of time, enabling device sizing, strategy decisions, and workflow preparation. Early planning cuts procedure time, reduces surprises, and improves scheduling and inventory decisions. This shifts critical work upstream, boosting OR efficiency and case predictability for PCI teams.

Mass General Brigham is piloting AI to handle notes, patient messages, and inbox triage. The system aims to free clinician time so they can see more patients and focus on complex care. Leaders stress human oversight to catch errors and bias. Early results on safety, cost, and access are pending. This pilot could cut labor costs and raise clinic capacity, but requires careful evaluation of throughput, costs, and patient safety before scaling.

UPMC is deploying AI system-wide to boost efficiency. The rollout targets administrative waste against the backdrop of U.S. healthcare's $1 trillion annual burden. The focus is cutting waste and speeding routine tasks through system-level change rather than isolated pilots. This signals a shift from testing to full adoption, requiring investments in change management alongside technology purchases.

Stanford built ChatEHR as a privacy-first AI layer for EHR systems. The project keeps patient data private while fitting into clinical workflows. Stanford Health Care designed it as a model other systems can copy. The approach prioritizes privacy-by-design, builds AI as a workflow layer rather than system replacement, and uses internal teams with clear guardrails for safe deployment. This offers a repeatable path for health systems adopting AI safely.

AI healthcare research and investment are accelerating rapidly. Papers rose from 158 (3.54%) in 2014 to 731 (16.33%) by October 2024. Market forecasts show growth from $11.2 billion in 2023 to $427.5 billion by 2032, a 47.6% annual growth rate. In oncology imaging, deep learning achieved 80.1% sensitivity versus 71.1% for conventional methods. However, risks include 200,000 annual healthcare data breaches and limited infrastructure in low-income countries. Leaders must invest in data governance, security, and validated pilots while planning for infrastructure needs.

These developments show AI moving from experimental to essential in healthcare. Success requires balancing innovation with safety, privacy with efficiency, and pilot programs with system-wide deployment. Healthcare leaders must act now on governance, security, and strategic planning to capture AI's benefits while managing its risks.
