Lack of care coordination and wide disparities in the cost and quality of care are pervasive problems in the U.S. health care system, perpetuated by the prevailing fee-for-service payment method. With the passage of the Affordable Care Act in 2010 and the enormous opportunities available to states to transform the health care delivery system, the accountable care organization (ACO) model is receiving increased attention for its potential to promote better value in health care spending without some of the perceived problems of past approaches. ACOs provide incentives to manage utilization, improve quality, and harness cost growth using a shared-savings model.
ACOs can take a variety of forms. Chief principles and prerequisites of the model include:
State Roles in Developing the Accountable Care Model
States have an important role to play in the development of the model. States are highly motivated to work on value, and at the same time, have significant infrastructure, unique levers, and extensive expertise to bring to the discussion. NASHP research indicates that state activity correlates roughly with five key components of the ACO model, as follows:
Data. States are providing leadership and specific funding to develop new data capabilities. In particular, states are developing multipayer databases to assist in the collection and analysis of health care data across payers. With recent funding the American Recovery and Reinvestment Act of 2009 (ARRA), states are at the forefront of health information technology (health IT) and health information exchange (HIE) development. States are leaders in building new infrastructure to collect and exchange data. This data infrastructure can be leveraged to support accountability and payment reform.
Designing and promoting new payment methods. States have an essential and unique role in convening stakeholders to talk about ACO development. Critical discussions among providers and payers in forming an ACO may run afoul of antitrust law. States are uniquely positioned to bring groups of providers and payers together under the “State Actions” doctrine to facilitate these discussions. In addition, pilot testing and other funding initiatives by states promote ACO payment innovation. States have enacted legislation and provided some funding for pilots that explore a variety of ACO payment models. Others are designing pilots as part of a broader health reform strategy already under way.
States are leveraging their health care purchasing power, including coverage for Medicaid members and state employees, to support new ACO payment and contracting models. And importantly, states can bring Medicare to the table. Through existing waivers and new opportunities in the Affordable Care Act, states can join with Medicare in their ACO development efforts. One state, Vermont, has already covered the Medicare portion of funding in a medical home initiative and will be able to expand beyond a pilot phase with Medicare’s participation.
Accountability measures. Through the adoption of statewide reporting requirements, states can lead in the design of accountability measures. States have provided leadership to enact systems for tracking and comparing cost and quality, a critical component of ACOs. Similarly, by using their significant health care purchasing power, states can promote accountability measures. By leveraging this purchasing power, states can develop performance-based contracts for ACOs and include population-based health care goals in these agreements. States are also using their convening role to bring together stakeholders to develop consensus on statewide health care standards. Finally, by tying standards to funding, states can promote accountability. States are requiring certain competencies and national certifications (such as National Committee for Quality Assurance medical home standards) for providers that participate in ACO and related medical home pilots.
Identifying and promoting systems of care. Providers seeking to form an ACO must address a variety of issues, such as retaining the critical mass of covered lives to function successfully and designing an attribution model. States can be useful partners here, as well. States are taking various approaches in promoting systems, by shaping regional systems of care through contracts and also by convening and educating local groups of providers to facilitate ACO development.
Supporting a continuum of care and the role of medical homes. States agree that strong primary care is critical to the ACO model, but they may take different approaches in promoting the patient-centered medical home (PCMH) within the ACO model. Some are building explicitly from their medical home pilots, while others are looking to the provider community to propose new configurations. Importantly, accountable care seeks to create “systemness” beyond the medical home. ACOs can provide a unifying force to a community or defined region—providers across the continuum of care, including specialists and hospitals, can be integrated through aligned cost and quality measures. Furthermore, the ACO model provides a budgeting methodology that allows some savings to remain in the community for reinvestment or expansion of services.
PCMHs and ACOs are mutually beneficial, synergistic models, although ACOs can function without a PCMH and medical homes can exist without an accountable care model. States recognize that the benefits of the patient-centered medical home can be enhanced through an ACO model, which can incentivize the broader service system to coordinate and improve care. Likewise, the ACO model will be more successful in delivering value if built around an evidence-based, high-performing, patient-centered medical home.
Federal Health Reform and State Opportunities for Accountable Care Organization Development
There are several opportunities for ACO development in the Affordable Care Act. The Medicare Shared Savings Program in Section 3022 offers an opportunity for providers to form ACOs and partake in shared savings with the Medicare program. Section 2706 provides Medicaid programs the opportunity to develop pediatric ACOs using the same incentive program described in Section 3022. Section 3021 establishes the Center for Medicare and Medicaid Innovation, to test innovative models for health care payment and delivery. In addition:
Key Themes: State Roles in Accountable Care Organization Development
The ACO model holds promise as a new and flexible structure for the promotion of value in health care systems. Supported by mature data systems and using a shared-savings model that recognizes the importance of health care outcomes, ACOs can incentivize what states want— controlled costs and better health outcomes—while addressing health care in a longitudinal and population-based way. States have an important role to play in the development of ACOs. They are using lessons from their own health reform efforts, including medical home initiatives and data capacity-building, as well as other projects, to promote the ACO model in innovative and timely ways.
