The Effect Of Next Generation Accountable Care Organizations On Medicare Expenditures

Area of Science:

• Health economics
• Healthcare policy
• Value-based care

Background:

• The Next Generation Accountable Care Organization (NGACO) model aimed to improve healthcare value for Medicare beneficiaries.
• It tested high financial risk, innovative payment mechanisms, and flexible care delivery.

Purpose of the Study:

• To examine the NGACO model's impact on Medicare Parts A and B spending.
• To evaluate the model's effectiveness in controlling healthcare costs.

Main Methods:

• Quasi-experimental methods were employed to analyze the model's effects.
• Data from 62 ACOs, over 4.2 million beneficiaries, and 91,000 practitioners were used.

Main Results:

• The NGACO model was associated with a $270 per beneficiary per year decrease in Medicare spending ($1.7 billion total).
• After shared savings, the model increased net Medicare spending by $56 per beneficiary ($96.7 million total).
• Spending declines grew over time, influenced by ACO performance, improvements, and the COVID-19 pandemic.

Conclusions:

• The NGACO model demonstrated initial success in reducing gross Medicare spending.
• Factors like ACO performance and payment structures influenced spending outcomes.
• Further analysis is needed to fully understand the long-term financial implications of such models.
