- An analysis of the first three years of the Medicare Shared Savings Program (MSSP) shows that most participating accountable care organizations (ACO) reduced spending and improved care quality in that time, according to a report from the HHS Office of Inspector General (OIG).
- The ACOs reduced spending by a total of $3.4 billion in the three years studied for a net reduction of nearly $1 billion, but some of them contributed far more to that figure than others. About half of the reduction was generated by just 36 ACOs out of the total 428, and three in that group were responsible for a quarter of that amount.
- A small subset of the participating ACOs had substantially reduced spending without sacrificing quality. That group reduced spending by an average of $673 per beneficiary, partly through increasing primary care services and reducing emergency department visits.
