The problem has a price tag

Kidney transplantation costs $447,000 per patient.¹ Roughly 20% of Medicare transplant payments—nearly $90,000 per patient—goes to hospital readmissions.² Across 28,000 annual kidney transplants,¹ that's over $2.5 billion in readmission costs alone.

But readmissions are only part of the story. When grafts fail, costs compound: $78,000 in additional lifetime costs per patient, with the national burden exceeding $1.3 billion annually.³ First-year failures add $95,000 to Medicare's tab, and patients who return to dialysis cost the system three times more than those with functioning grafts.⁴

Up to 65% of kidney transplant recipients are readmitted within their first year.² Up to 50% of early readmissions are preventable.² The patterns are predictable: infections that escalate because patients waited too long to call, medication issues caught too late, rejection episodes that presented subtly until they didn't.

Not random complications. Failures of monitoring between visits.

Why the economics didn't work

Preventing readmissions requires what transplant programs don't have: capacity for intensive post-discharge engagement. Consistent outreach. Real-time symptom monitoring. Rapid escalation when something's wrong.

Coordinators already manage 50–100+ patients across every stage of the transplant journey. Adding daily check-ins for every recent discharge would require hiring staff—or burning out the staff they have.

The interventions that work aren't mysterious. One quality improvement initiative cut early readmissions by 50% using structured discharge protocols and medication education.⁶ A 2024 randomized trial showed that SMS reminders significantly improve immunosuppressant adherence in kidney transplant recipients—direct evidence that low-friction digital outreach works in this population.⁷

The problem was never knowing what works. It was delivering it at scale.

What changed

Regulatory pressure is now mandatory. Starting July 2025, CMS's IOTA Model ties reimbursement to post-transplant outcomes for 103 kidney transplant hospitals. Programs face up to $15,000 upside or downside risk per Medicare transplant.⁵ Readmission prevention isn't optional anymore—it's financial exposure.

AI handles routine monitoring at scale. Natural language processing can now assess patient-reported symptoms, flag concerning patterns, and escalate appropriately—without human review of every interaction. Coordinators focus on patients who need clinical judgment.

Evidence validates the approach. Digital engagement improves transplant outcomes, but only with two-way communication and human backup for complex issues.⁸ Static reminders fail. Interactive systems with clinical oversight succeed.

What we're building at Stitch

The infrastructure that makes readmission prevention economically viable: AI-powered monitoring that catches problems early, human coordination for issues that need judgment, clear metrics for the ROI conversation.

For transplant programs facing IOTA, that means fewer preventable readmissions, coordinators working at the top of their capacity, and numbers that satisfy the CFO.

The cost of a readmission: $20,000–$50,000.²
The cost of graft failure: $78,000+.³
The cost of preventing either: far less.
