About Us

Our Mission

Ultimately, our goal is to build healthy communities and a sustainable rural health care system by enabling providers, clinicians, and other health care professionals to deliver the highest-quality care, at the most optimal cost, for the people of the region. We do this by collecting data on quality and cost metrics, promoting evidence-based medicine, encouraging patient engagement, and increasing the focus on whole-person wellness — all in an environment that provides support to our participating providers.

The ACO model has four essential priorities, which we call the “Quadruple Aim:” 

Improve the quality of care 

We continually look for improvement opportunities that may not be obvious. We work to better understand these opportunities by utilizing data from our network and our federal and commercial health plan partners. We use the data findings to create best practices that are shared and implemented among all providers and to inform and support providers as they work toward common goals for the region.

Increase patient satisfaction

We want to ensure that patients are getting the right care at the right time, in the right location, as well as create partnerships to offer patients more accessible and integrated community-based resources. We want to understand patients’ needs and help providers improve their care. We know that when patients are well cared for, and when we focus on prevention and disease management in addition to treatment for illness and injury, patients live happier, more fulfilling lives.

Make healthcare more effective and efficient

When the cost of health care increases, families feel it, and this can deter some from seeking treatment, leading to poor health. By working together to make the system more effective and efficient, we help our participating providers create a patient-centered environment focused on healthy outcomes rather than procedure volume. This will help reduce the cost of healthcare over time.

Increase provider satisfaction

Providers, clinicians, and other health care professionals want to help and heal people. Our goal is to support our provider teams by giving them the tools and supports to spend more time with patients, delivering care. In a traditional fee-for-service payment system, the focus is on sickness care rather than wellness and health care. Providers are paid by the appointment and not for the outcome.  The ACO has partnered with payers and government entities under valued-based-payment (VBP) models to change the incentive to keep our community healthy and are rewarded with shared savings for doing so.   The focus is on value, not simply volume. 

Our History

Adirondacks ACO was officially established in May 2013, with our founding members, Champlain Valley Physicians Hospital (CVPH) and Fletcher Allen Medical Group (FAMG), in collaboration with other area hospitals, Hudson Headwaters Health Network, independent physician groups, and The University of Vermont Medical Center (UVMMC).

We were originally formed to carry on the work begun by the Adirondack Region Medical Home Pilot, which began in 2010 and ended in 2017. The Pilot was created to help transform the way primary care is delivered in the Adirondacks and northern New York State. The Pilot recognized all participating primary care practices as National Committee for Quality Assurance (NCQA) Patient-Centered Medical Homes (most at Level III), which gave them a larger role in coordinating patient care. The Pilot also established procedures for 24/7 access to care, initiated transitional care programs, and made significant investments in technology and enhanced care coordination.

Adirondacks ACO entered its first contract with Medicare in 2014 as part of the Medicare Shared Savings Program (MSSP), which addressed the rising cost of care by incentivizing providers to focus on value over volume. The program offered accountable care organizations the opportunity to coordinate care for Medicare beneficiaries and share in potential cost-savings if certain quality measures were met.

Following the success of that contract, ADKs ACO has expanded its contracts with government plans and developed similar value-based-payment contracts with commercial payers.

We at ADKs ACO carry on the work of the Medical Home, as we continue to work with primary care providers and hospitals, and expand into working with mental health providers, substance use treatment centers, and other sectors in health care. Our network providers are committed to whole-person care and to improving health care for all who live and work in our region.

ADKs ACO team members bring both experience and passion to their roles. This is a unique team that has bonded over the mission to improve the health of our region and, in turn, the lives of our neighbors.
