Will accountable care swallow up primary care?

If you've heard something about "accountable care organizations" (ACOs) in discussions of health care reforms, but you're not quite sure what they are or where they're supposed to fit in, you might find this "Perspective" piece from the New England Journal of Medicine useful. In short compass it defines the term and relates it to the other biggie in health care redesign, the patient-centered medical home (PCMH).

To get the definition out of the way, "an ACO is a provider-led organization whose mission is to manage the full continuum of care and be accountable for the overall costs and quality of care for a defined population." (Harks back to the day when managed care wore a white hat, doesn't it?) While the PCMH has been much discussed in family medicine over the past five years, at least, the term ACO seems to have emerged only recently.

The NEJM article makes the point that the PCMH and the ACO are, or can and should be, complementary: The PCMH is a model for redesigned primary care, and the ACO is a model for ensuring that the rest of the delivery system works in concert with the PCMH by aligning incentives for the rest of the system with those of primary care.

Sounds neat, doesn't it? The ACO is a way to get referral specialists, hospitals and all the rest to see things our way. Except ...

As the NEJM article puts it, "The fact that the ACO model does not explicitly require support for primary care has led to considerable concern that ACOs dominated by hospitals or specialists would not adequately invest in primary care – or that hospitals and specialists would garner a disproportionate share of any savings." The ACO may be a "provider-led organization," but the providers leading it may well be hospitals, large multispecialty groups or other entities who have not so far proved to be far seeing or even to understand primary care. The NEJM article lists three requirements for successful integration of PCMHs into ACOs:

• Alignment of accreditation and certification criteria for the two organizations: "No ACO accreditation or certification process has yet been developed, but when one is, it will be critical to include criteria that ensure sufficient primary care capacity for the patient population and to closely align the standards with those of PCMH recognition."
• A common set of primary care performance measures: "Performance measurement for determining the amount of shared savings or other financial incentives for ACOs must weight primary care measures heavily rather than focus narrowly on metrics related to hospital care."
• Wise alignment of incentives: "The payment mechanisms used must align the incentives of the two models to increase accountability for total costs across the continuum of care while ensuring that a sufficient investment is made in primary care capacity."

So all we need to do to achieve a health care delivery system we can be proud of is redesign primary care, redesign the rest of care, avoid the mistakes we've made chronically in past attempts to fix the system, develop system-wide performance measures with a primary care orientation and, oh yes, shift the center of power of the system from secondary and tertiary care to primary care. I hope we're up to the challenge.

Beyond PCMH: Is your practice an "accountable care organization"?

The patient-centered medical home model, which has been in the spotlight over the last few years, may soon have to share the stage with a new model: the "accountable care organization."

What's an accountable care organization? According to a recent report from Harold Miller, executive director of the Center for Health Care Quality and Payment Reform, an accountable care organization is "a health care provider or group of providers that accepts accountability for the total cost of care received by a population."

What does a practice need in order to act as an accountable care organization? Miller identifies eight elements:

1. Complete and timely information (including cost information) about your patients and the services they are receiving. Miller notes that most practices will need "significant assistance" from payers in order to obtain this information.
2. Technology and skills for population management and coordination of care, such as using clinical guidelines and monitoring compliance with them, analyzing data on resource use and utilizing a patient registry.
3. Adequate resources for patient education and self-management support.
4. A culture of teamwork among the staff of the practice.
5. Coordinated relationships with specialists and other providers.
6. The ability to measure and report on the quality of care.
7. Infrastructure and skills for management of financial risk.
8. A commitment by the organization’s leadership to improve value and create operational accountability.
   
   

How does an accountable care organization differ from a patient-centered medical home? According to Miller, "Most initiatives today to help primary care practices become Medical Homes do not require that the primary care practice accept any accountability for the total costs of care for their patients or for population-level quality outcomes. Even though many of the enhanced resources and tools being developed and used by Medical Homes, such as electronic health records, patient registries, patient education on chronic disease management, and more responsive scheduling, could help improve quality and reduce total costs, there is no guarantee that they will do so unless the primary care practice actually focuses on improving those outcomes as an explicit goal and uses the medical home tools to achieve the goal. Indeed, the Congressional Budget Office, in evaluating various health delivery reform options, estimated that paying for Medical Homes for chronically ill beneficiaries in Medicare would increase spending by $5.6 billion, rather than reduce costs."

Miller continues, "This implies that while becoming a Medical Home could help a primary care practice become an Accountable Care Organization, it is not sufficient. Conversely, in order to function effectively as an Accountable Care Organization, it may not be necessary for a primary care practice to meet all of the detailed standards that organizations such as the National Committee for Quality Assurance (NCQA) require of primary care practices in order to be formally designated as a 'Patient-Centered Medical Home.' Indeed, detailed accreditation standards are being used in medical home programs partly because payers are concerned about whether making higher payments to primary care practices to enable them to serve as medical homes will actually result in improved outcomes for patients and lower costs for payers. Since there is not strong evidence that all of the structural and process standards established for medical homes are necessary for improved patient outcomes and some may be difficult or expensive for practices to achieve, and because some practices that would not meet these standards have been successful in proactively managing and coordinating their patients’ care, a primary care practice should not be precluded from serving as an Accountable Care Organization simply because it has not met accreditation standards as a Medical Home."
