The Integrated Delivery Network (IDN)
One Company. One Mission. The Entire Continuum.
Kaiser Permanente is the example everyone uses, and for good reason. Here’s how it works:
You’re a Kaiser member. You see your primary care doctor at a Kaiser clinic. She refers you to a Kaiser cardiologist. Your echocardiogram happens at a Kaiser imaging center. If you need surgery, it’s at a Kaiser hospital, performed by a Kaiser surgeon. Your post-surgical rehab is at a Kaiser facility. Your prescriptions are filled at a Kaiser pharmacy. And the insurance plan that pays for all of this? That’s Kaiser too.
One organization. Every step.
What It Is
An Integrated Delivery Network is a single corporate entity that owns and operates the full continuum of care: hospitals, physician groups, ambulatory centers, post-acute facilities, and sometimes a health plan. Everything operates under unified governance, shared financials, and a common electronic health record.
Why It Exists
The fundamental problem in healthcare is fragmentation. Your PCP doesn’t talk to your specialist. Your hospital doesn’t coordinate with your rehab facility. Your insurer and your doctor have opposite incentives.
The IDN eliminates these walls by putting everything under one roof. When the hospital, the doctors, and the insurance plan share the same P&L, there’s no incentive to do unnecessary surgery (the plan pays for it), no incentive to skip follow-up care (the system absorbs the readmission cost), and no information gaps (everyone uses the same EHR).
How It’s Organized
The IDN is the parent entity at the top of the hierarchy. Everything else — hospitals, physician groups, ambulatory networks, post-acute facilities, sometimes the health plan — are subsidiaries or divisions.
Intermountain Health in Utah is a good example. It owns 33 hospitals, employs over 4,000 physicians, operates a health plan (SelectHealth), runs home health and hospice services, and manages a network of clinics. One board of trustees oversees the whole thing.
When the IDN also owns the health plan (Kaiser, Geisinger, UPMC), it becomes fully vertically integrated — controlling both the insurance premium and the care delivery.
The Tradeoffs
The upside is coordination. Seamless care across the continuum. Unified data. Population health management. Maximum alignment under risk contracts.
The downside is weight. IDNs are extremely capital-intensive. Decision-making can be slow and bureaucratic. Physicians are employees, not owners — and some chafe under corporate management. In markets where an IDN dominates, antitrust regulators are paying close attention.
The Bottom Line
The IDN is the most powerful organizational structure in healthcare. It solves the coordination problem by owning everything. But that power comes with the burden of scale — massive capital requirements, bureaucratic decision-making, and the challenge of running a $10-50 billion enterprise without losing the personal touch that patients need.
