Accountable Care Organizations, Explained

Significant confusion remains about Accountable Care. This overview from Kaiser Health News is a good primer for Hospitals, ACOs, and post acute providers.

ACOsWhile existing ACOs and Hospitals are generally better aware, post acute providers who ignore the changing business landscape do so with certain peril. Either plan your business strategy to be a valued partner in the ACO model, or wait for Accountable Care to happen to you. Those who plan and make it easy to do business with them under ACO the model will thrive. Those who wait for it to happen and do things the way they've always done them will be eliminated from the highest paying, fastest growing services. The latter group will fail at alarming rates.  

Providers that are more directly in the line of fire and face reimbursement penalties for high readmission rates tend to be more aware. These include providers like large hospitals, large physician practices, and few very large home health agencies. Hospital leadership tends to be more keyed in on Accountable Care as an opportunity to reduce costs and improve quality, and appreciates the financial implications. An overwhelming majority of post acute providers are surprisingly unclear on the emergence of ACOs and what it means to them. The more advanced groups are already considering what infraststructure, technology and management skills they require to thrive in the new era of Accountable Care.

ACO is the hottest three-letter word in health care

Accountable care organizations take up only seven pages of the massive new health law yet have become one of the most talked about provisions. This latest model for delivering services offers doctors and hospitals financial incentives to provide good quality care to Medicare beneficiaries while keeping down costs. A cottage industry of consultants has sprung up to help even ordinary hospitals become the first ACOs on the block.

ACOs were compared to the elusive unicorn: everyone seemed to know what it looks like, but no one had actually seen one. Nonetheless, the health care industry embarked on a frenzied quest to create them as quickly as possible. But when the Obama administration released its proposed rule on ACOs, industry excitement fizzled. Hospital and doctor groups complained that the program created more financial risks than rewards and imposed onerous reporting requirements.

Thursday, after many delays and false starts, the administration at last released its final rule on how ACOs should work, including several concessions likely to assuage the concerns of skittish providers.

What is an accountable care organization?

An ACO is a network of doctors and hospitals that shares responsibility for providing care to patients. In the new law, an ACO would agree to manage all of the health care needs of a minimum of 5,000 Medicare beneficiaries for at least three years.

Think of it as buying a television, says Harold Miller, president and CEO of the Network for Regional Healthcare Improvement and executive director of the Center for Healthcare Quality & Payment Reform in Pittsburgh. A TV manufacturer like Sony may contract with many suppliers to build sets. Like Sony does for TVs, Miller says, an ACO would bring together the different component parts of care for the patient – primary care, specialists, hospitals, home health care, etc. – and ensure that all of the "parts work well together."

The problem today, Miller says, is that patients are getting each part of their health care separately. "People want to buy individual circuit boards, not a whole TV,” he says. “If we can show them that the TV works better, maybe they'll buy it," rather than assembling a patchwork of services themselves. "But ACOs will need to prove that the overall health care product they’re creating does work better and costs less in order to encourage patients and payers to buy it."

When will ACOs begin operating?

The government will begin receiving its initial round of applications for the ACO Shared Savings Program in January 2012, and the first ACOs are expected to launch in April.  But the race to form ACOs has already begun. Hospitals, physician practices and insurers across the country, from New Hampshire to Arizona, are announcing their plans to form ACOs, not only for Medicare beneficiaries but for patients with private insurance as well. Some groups have already created what they call ACOs.

In addition, CMS created a second strategy, called the Pioneer Program, for high-performing health systems to pocket more of the expected savings in exchange for taking on greater financial risk.

Why did Congress include ACOs in the law?

As lawmakers search for ways to reduce the national deficit, Medicare is a prime target. With baby boomers entering retirement age, the costs of the program for elderly and disabled Americans are expected to soar.

ACOs make providers jointly accountable for the health of their patients, giving them financial incentives to cooperate and save money by avoiding unnecessary tests and procedures. For ACOs to work they have to seamlessly share information. Those that save money while also meeting quality targets would keep a portion of the savings. Providers can choose to be at risk of losing money if they want to aim for a bigger reward, or they can enter the program with no risk at all.

HHS estimates that ACOs could save Medicare up to $940 million in the first four years. That’s far less than one percent of Medicare spending during that period. If the program is successful, it can be expanded by the Secretary of Health and Human Services.

How would ACOs be paid?

In Medicare’s traditional fee-for-service payment system, doctors and hospitals generally are paid more when they give patients more tests and do more procedures. That drives up costs, experts say. ACOs wouldn’t do away with fee for service but would create savings incentives by offering bonuses when providers keep costs down. Doctors and hospitals would have to meet specific quality benchmarks, focusing on prevention and carefully managing patients with chronic diseases. In other words, providers would get paid more for keeping their patients healthy and out of the hospital.

If an ACO is not able to save money, it could be stuck with the costs of investments made to improve care, such as adding new nurse care managers, and also may have to pay a penalty if they don't meet performance and savings benchmarks. ACOs sponsored by physicians or rural providers, however, can apply to receive payments in advance to help them build the infrastructure necessary for coordinated care – a concession the Obama administration made after complaints from rural hospitals.  

How would an ACO be different for patients?

Providers who are part of an ACO are required to alert their patients, who can choose to go to another doctor if they are uncomfortable participating. The patient can decline to have his data shared within the ACO. But although physicians will likely want to refer patients to hospitals and specialists within the ACO network, patients would still be free to see doctors of their choice outside the network without paying more. ACOs also will be under pressure to provide high quality care because if they don't meet standards, they won’t get to share in any savings – and could lose their contracts.

Who's in charge — hospitals, doctors or insurers?

Hospitals, primary care providers and other physicians are in charge of an ACO, but insurers can also play a role.

Some regions of the country, including parts of California, already have large multispecialty physician groups that may become an ACO on their own, likely by networking with neighboring hospitals. "A lot of health care organizations are going to dust off the existing structures they had in place" in the past, says Kelly Devers, a senior fellow at the nonprofit Urban Institute.

In other regions, large hospital systems are scrambling to buy up physician practices with the goal of becoming ACOs that directly employ the majority of their providers. Because hospitals usually have access to capital, they may have an easier time than doctors in financing the initial investment required by an ACO.

Some of the largest health insurers in the country, including Humana, United Healthcare and Cigna, already have announced plans to form their own ACOs for the private market. Insurers say they are essential to the success of an ACO because they track and collect the data on patients that allow systems to track patient care and report on the results.

If I don't like HMOs, why should I consider an ACO?

ACOs may sound a lot like health maintenance organizations. "Some people say ACOs are HMOs in drag," says Devers. But there are some critical differences – notably, an ACO patient is not required to stay in the network.

Steve Lieberman, Deputy Director for Policy and Analysis at the National Governors Association, explains that ACOs aim to replicate "the performance of an HMO" in holding down the cost of care while avoiding "the structural features that give the HMO control over [patient] referral patterns," which limited patient options and created a consumer backlash in the 1990s.

What can go wrong?

Lieberman cautions that ACOs are not a panacea. "ACO has become the three-letter health acronym of the year, if not the decade," he says. The health industry tends to operate with "kind of a herd behavior," rushing to implement an idea "without working through the detailed business questions of how they'll work."

Many health care economists fear that the race to form ACOs could have a significant downside: hospital mergers and provider consolidation. As hospitals position themselves to become integrated systems, many are joining forces and purchasing physician practices, leaving fewer independent hospitals and doctors. Greater market share gives these health systems more leverage in negotiations with insurers, which can drive up health costs.

But Lieberman says while ACOs could accelerate consolidations, it’s already "such a powerful and pervasive trend that it's a little like worrying about the calories I get when I eat the maraschino cherry on top of my hot fudge sundae. It's a serious public policy issue with or without ACOs."

Are there any possible legal concerns?

Doctors, hospitals and others in the health care industry have raised concerns that ACOs could run afoul of antitrust and anti-fraud laws, which try to limit market power that drives up prices and stifles competition. One concern is that ACOs, particularly those in rural markets, could grow so large that they would employ the majority of providers in a region.

To help providers avoid legal problems, the U.S. Justice Department's antitrust division promises to provide an expedited, non-mandatory, antitrust review process for these new doctor-hospital partnerships.
