Winchester Hospital’s Accountable Care Organization Among Best in the Country


WinACO tops in the country for savings

Winchester, MA (September 10, 2015) – The WinACO finished first nationally with the highest percentage of savings (16 percent) over and above the target set by CMS. For each ACO, CMS sets an individualized cost reduction goal based on the organization’s prior expenditures.

The WinACO also had the third highest savings per patient in the country with the most savings per patient in New England – a savings of $792 per beneficiary.

The Winchester Community Accountable Care Organization (WinACO) generated more than $10.9 million in shared savings, according to a quality and financial performance report issued by the Centers for Medicare & Medicaid Services. As a result of this savings, WinACO will see $4.94 million in earned shared savings.

“These results are extremely encouraging because it means we’re making sure our patients stay well and out of the hospital,” said Dale Lodge, CEO of Winchester Hospital. “The WinACO is proof that we can provide a high level of coordinated care that will bring better value to the health care dollar.”

Across the country three out of four Medicare Accountable Care Organizations did not slow health spending enough to earn bonuses in 2014.

When an ACO demonstrates that it has achieved high-quality care and effectively reduces spending of health care dollars above certain thresholds, it is able to share in the savings generated for Medicare. In 2014, 20 Pioneer and 333 Shared Savings Program ACOs generated more than $411 million in savings, which includes all ACOs savings and losses. The results also show that ACOs with more experience in the program tend to perform better over time.

Medicare ACOs are groups of doctors, hospitals, and other health care providers, who come together voluntarily to provide coordinated high quality care to their Medicare patients. The goal of coordinated care is to ensure that patients, especially the chronically ill, get the right care at the right time, while avoiding unnecessary duplication of services and preventing medical errors. When an ACO exceeds quality and financial thresholds – demonstrating achievement of high-quality care and wiser spending of health care dollars – it is able to share in the savings generated for Medicare.

The WinACO — selected as one of 106 new Medicare ACOs in 2013 — includes approximately 100 providers (physicians, nurse practitioners and physician assistants) participating in this ACO, caring for approximately 8,000 Medicare patients for 2015.

To further enhance its impact, in 2016, WinACO will join the Lahey Clinical Performance ACO (LCP-ACO). LCP-ACO also performed well, generating $11.7 million in shared savings in 2014.
