As ACO Medical Director, Dr. Ebert oversees medical management strategies, clinical delivery models, ACO quality measurements and financial performance of commercial contracts. He partners with D-H Community Group Practices and Affiliate Hospitals for ACO initiatives and quality metric performance. Additionally, he is a board member of the statewide ACO, OneCare Vermont.

We can clearly do a better job at more cost-effectively managing health care. If you stay on top of disease processes and manage them as actively as possible, you can typically decrease people's need to go to the emergency department or be admitted to the hospital, so you get both better care and lower costs.

Engaging our patients, families, schools, employers, faith-based communities and others, we can build systems to improve health and deliver health care in the safest, lowest-cost, least complicated setting that is right for everyone, based on the best science that we have.

There is a profound interaction in this country between work and health. But when people think about the health of a population, they think about people as patients, not as workers. Yet people's work affect their health and their health affects their capabilities as workers; we can more effectively leverage that relationship to improve both their health and their work.
