Introduction
The Centers for Medicare & Medicaid Services (CMS) has finalized a transformative six-year model aimed at increasing access to kidney transplants in the U.S. The Increasing Organ Transplant Access (IOTA) Model, first proposed in May 2024, incorporates key adjustments based on hospital feedback and is set to launch on July 1, 2025. This model is a significant step in addressing the critical shortage of donor kidneys while improving patient outcomes.
Overview of the IOTA Model
Goals of the Model
The IOTA Model seeks to:
- Increase the number of kidney transplants performed annually.
- Enhance the efficiency of organ allocation to reduce the extensive waiting list.
- Transition kidney transplant hospitals into value-based care systems.
CMS Administrator Chiquita Brooks-LaSure emphasized the importance of the model, stating, “The IOTA Model will increase the number of kidney transplants that will not only save lives but will enable people to live longer and healthier ones.”
Key Features of the IOTA Model
The model includes:
- Mandatory Participation: Involving 103 kidney transplant hospitals across 50% of donation service areas.
- Performance-Based Metrics: Evaluating hospitals on:
- Total number of transplants.
- Acceptance rates for organ offers.
- Patient health outcomes post-transplant.
- Financial Incentives:
- Positive incentives for high-performing hospitals.
- Negative penalties for underperformance (starting from year two).
Stakeholder Feedback and Adjustments
Delayed Implementation and Financial Adjustments
Initially set for January 1, 2025, the start date was delayed to July following stakeholder feedback that the timeline was unrealistic. CMS also increased the potential performance score bonus from $8,000 to $15,000 per transplant, providing stronger incentives for hospitals.
Quality Measures and Health Equity Considerations
CMS addressed concerns by eliminating three quality measures and making all health equity plans voluntary. Hospitals are encouraged to address social determinants of health, such as transportation assistance, to improve transplant accessibility.
Impact on Kidney Transplantation
Addressing the Transplant Waiting List
The IOTA Model aims to tackle the long-standing issue of kidney shortages. Currently, 90,000 patients are on the kidney transplant waiting list, with some waiting up to five years. By incentivizing hospitals to accept and utilize more donor kidneys, the model could significantly reduce these numbers.
Financial Incentives and Social Determinants of Health
Hospitals will operate within a tiered financial framework:
- Performance-Based Payments: Bonuses for meeting transplant targets.
- Neutral Zone: Hospitals neither gain nor lose financial support.
- Penalties: Applied to underperforming hospitals from the second year onward.
Addressing social determinants of health, such as providing transportation to patients, is a crucial component to ensure equitable access to transplants.
Simultaneous Policy Developments
HRSA’s Overhaul of the Organ Procurement and Transplantation Network
The IOTA Model coincides with a broader effort by the Health Resources and Services Administration (HRSA) to revamp the Organ Procurement and Transplantation Network (OPTN). This includes improving organ distribution efficiency and reducing systemic barriers.
Legislative Actions on Organ Procurement
In September 2023, the Biden administration enacted legislation prohibiting the United Network for Organ Sharing (UNOS) from being the sole contractor for OPTN. This change aims to foster competition and innovation in organ procurement processes.
Conclusion
The IOTA Model represents a landmark shift in kidney transplantation policy, addressing both supply chain inefficiencies and patient access barriers. By integrating financial incentives with value-based care principles, CMS seeks to improve outcomes for the thousands of Americans suffering from end-stage renal disease. The model’s emphasis on addressing social determinants of health further underscores its commitment to equity.
As the healthcare system navigates these changes, the simultaneous efforts by HRSA and legislative actions will play a pivotal role in reshaping organ transplantation in the United States.
