Introduction
In 2014, on the heels of a failed attempt to create a single-payer health care system in Vermont, policymakers turned their attention to how they might achieve their goal — lower health care spending and improved health outcomes — without disrupting the existing payment system. Their idea was to encourage the state’s largest payers — Medicare, Medicaid, and Blue Cross and Blue Shield of Vermont — to move more quickly from fee-for-service to risk-based contracting. In so doing, they would also encourage providers to pursue the state’s goals for improving residents’ health.
The concept appealed to OneCare Vermont, a large accountable care organization (ACO) that had engaged more than half the state’s physicians and nearly all its hospitals in its network but had struggled to earn savings in its previous contracts with insurers.
Under the “all-payer” ACO model, the three payers would steadily increase the number of patients cared for under risk-based contracts and provide additional financial support to OneCare to coordinate care for individuals considered to be high medical risks. In return, OneCare would take on downside financial risk for itself and participating hospitals, a move it hoped would spur the latter to collaborate with community partners in helping patients beyond their institutions’ walls.
OneCare’s vision is to unite the physical health, mental health, and social services sectors in serving patients with the most complex needs, much as the federal Accountable Health Communities initiative seeks to forge clinical and community partnerships to address factors such as unstable housing or social isolation that contribute to poor health.1 Rather than hiring its own staff to organize this effort, OneCare is relying on care coordinators already in the field as a result of Vermont’s Blueprint for Health. The Blueprint for Health, a statewide initiative, compels public and private payers to support nurses, social workers, community health workers, and others working to help patients manage their chronic conditions, find treatment for addiction and other behavioral health conditions, and connect with social supports.
OneCare offers these care coordinators additional funding as well as training and tools to collaborate. Its approach is purposefully nondirective: it assumes that given resources and opportunities to collaborate, communities will devise their own solutions. “We are not trying to come into a community and set up a different system of care,” says Sara Barry, OneCare’s director of clinical and quality improvement. “We’re trying to say, ‘How do we align with what you already have and bring those services more closely together?’”
This case study examines OneCare’s community-driven approach to care coordination, which it piloted in 2017 among a subset (around 29,000) of the state’s Medicaid beneficiaries. This year, the ACO is accountable for 42,000 Medicaid beneficiaries as well as 72,000 Medicare and Blue Cross and Blue Shield members.2 By 2022, Vermont aims to have nearly 70 percent of its 624,000 residents attributed to an ACO.3 Although the initiative is in its early stages, Vermont’s experiment in forging partnerships among health care payers and between clinical and community providers may offer lessons about the potential of care coordination to wring value out of a fragmented health care system.
Note: Blueprint for Health legislation passed in 2006. A 2010 law expanded the pilot statewide and guaranteed by 2013 access to providers that wanted to participate. As of the first quarter of 2018, nearly all of Vermont’s primary care practices — 140 — had achieved patient-centered medical home recognition.
Building on Vermont’s History of Reform
OneCare Vermont was created in 2012 by two academic medical centers serving the state — the University of Vermont Medical Center and the Dartmouth-Hitchcock health system — and now includes 10 of the state’s 14 hospitals, a majority of its primary care and specialty care practices, and 21 of its 40 nursing homes.4 As noted above, what makes it different from many other ACOs is its engagement of partners other than hospitals and physicians: Area Agencies on Aging, mental health agencies, home health providers, and other community groups that are part of the ACO but unlike participating hospitals not at financial risk for its results. Its ability to do so is a function of the state’s past reforms to the health care delivery system, most notably the Blueprint for Health, which provides financial support for creation of patient-centered medical homes and “community health teams” made up of nurses, social workers, dietitians, asthma educators, community health workers, and others in each of the state’s 14 health service areas (HSAs).5
What Is the All-Payer ACO?
Vermont is partnering with the federal government in an ambitious effort to shift nearly all payment for medical services from a fee-for-service model to a value-based one that rewards providers for achieving the state’s cost-containment and quality-improvement goals. Under the all-payer model, Medicaid, Medicare, and Blue Cross and Blue Shield of Vermont (which has a nearly 90 percent share of the commercial market) have agreed to enter into contracts that require providers to assume the risk for meeting financial targets and performance benchmarks.
Over the course of five years, participants are expected to incrementally increase enrollment such that by 2022, 90 percent of all Medicare beneficiaries and 70 percent of commercially insured residents are covered by risk-based contracts (the state has not set specific targets for the Medicaid population). The approach has some similarities to that of Maryland, which seeks to contain health care spending by setting the rates by which all third parties — Medicare, Medicaid, and commercial insurers — pay for hospital care.6
Medicaid Next-Generation Pilot
In 2017, OneCare assumed financial risk for some 29,000 Medicaid beneficiaries (about 20 percent of the state’s total) in four regions: Berlin, Burlington, Middlebury, and St. Albans.7 It took responsibility for providing most medical and behavioral health services for these beneficiaries, from a budget of $90 million.8 Like Medicare’s Next Generation ACO Model, which was also launched in 2017, the Medicaid program offered the ACO the option to receive capitated payments.9 If actual expenditures in 2017 fell below the budgeted amount, OneCare would keep the first 3 percent of savings; if expenditures exceeded it, OneCare would make up the first 3 percent.
As part of the agreement, Vermont’s Medicaid agency ceded to OneCare some of its care management functions. The agency had been focusing its support on patients in the top 5 percent of health care spending. OneCare proposed to engage a broader population, including those with chronic diseases or behavioral health conditions who might be at rising risk. It also wanted to do away with eligibility criteria restricting which patients could be offered support, because the ACO’s leaders said these were administratively burdensome and left too many people out.
To identify Medicaid beneficiaries who may need support, OneCare analysts aggregate demographic information, data from the medical records of physicians and hospitals, and claims data supplied by Vermont’s Medicaid agency. They then analyze the data using a risk-prediction algorithm licensed through Johns Hopkins University that categorizes each Medicaid beneficiary — a mix of adults (45%); children (49%); and aged, blind, and disabled individuals (6%) — into one of four groups based on their predicted morbidity over the next year (Exhibit 1).10 Patients’ risk categorization is then provided to local care coordinators, who can then adjust it based on their knowledge of the patients and conversations with clinicians.
For example, based on claims data alone, an individual may not be identified as being at high or rising risk. But the care coordinator understands this person needs additional support because of a recent bout of homelessness or a death in the family.
