A New Partnership to Close the Primary Care Gap

Lumeris and Google Cloud have partnered to confront one of healthcare’s most urgent challenges: a massive shortfall in access to primary care. We’re combining deep clinical expertise and cutting-edge AI to support care teams and bring better care to more people—at scale.

Annual demand for care exceeds 2.5 billion hours, but less than 500 million hours are available.

An Unignorable Deficit

Every year, the U.S. is hundreds of millions of hours short of primary care. That gap means missed diagnoses, delayed treatments, and unequal access to care for millions. It’s not just a system strain—it’s a public health crisis.

AI That Expands Access—Without Replacing Care

Tom™, Lumeris’ Primary Care as a Service™ platform, will be powered by Google Cloud’s secure infrastructure and advanced AI models. Embedded directly in clinical workflows, Tom supports teams by executing a range of tasks across continuum of care, removing administrative burdens to allow care teams focus their valuable time on clinical decisions.

This partnership is built on the belief that technology should amplify human care, not replace it

“More than 100 million Americans lack access to primary care, and another 100 million are receiving suboptimal care. Now, two world-class companies — Google and Lumeris—are bringing their unique capabilities together to help solve this crisis.”

John Doerr, chairman of Kleiner Perkins, and board member of Lumeris.

Highlights of the Google Cloud and Lumeris partnership

Purpose built to scale: Tom, powered by Google Cloud, will address healthcare outcomes by supporting care coordination, chronic disease management and preventive health services with secure infrastructure built to serve millions of Americans nationwide.

Distinctive caregiver and patient experiences: By combining Google Cloud’s AI capabilities with Lumeris’ proven primary care expertise, Tom will enable health systems and other primary care organizations to scale faster while enhancing operations, physician workflows and patient outcomes, delivered through deeply personalized patient experiences.

Turning data into actions: This partnership will accelerate Lumeris’ ability to convert fragmented data from scores of electronic health records (EHRs), health insurance payer feeds, and consumer sources into actionable intelligence—helping to close the loop between payers and care teams by surfacing best next actions within clinical context and workflows.

AI that knows healthcare: Gemini Flash and Chirp3-HD don’t just enable AI—they power intelligent, conversational experiences that Lumeris uses in Tom to enhance clinical care.

Shared commitment to responsible AI: Google Cloud and Lumeris share a deep commitment to responsible AI. Google Cloud’s work is grounded in Google’s AI Principles, prioritizing fairness, safety, privacy, transparency, and accountability across its solutions. Lumeris’ AI-enabled platform supports care teams, embedding human oversight and accountability into every layer of its healthcare solutions.

Lumeris working with Google Cloud and other partners means Tom’s capabilities will remain current with the accelerating pace of AI innovation, ensuring Tom’s users are deploying the most advanced, highest value Primary Care as a Service capabilities.
