Association between specialist compensation and Accountable Care Organization performance

Area of Science:

• Health Services Research
• Healthcare Management
• Accountable Care Organizations

Background:

• Accountable Care Organizations (ACOs) aim to improve healthcare quality and reduce costs.
• Specialist compensation models are a key area for potential cost savings within ACOs.
• Understanding the impact of cost-reduction incentives in specialist compensation is crucial for ACO success.

Purpose of the Study:

• To evaluate whether Medicare Shared Savings Program ACOs that incorporated cost reduction measures in specialist compensation demonstrated superior performance.
• To determine the association between using cost reduction measures in specialist compensation and ACO financial savings, outpatient spending, and specialist utilization.

Main Methods:

• A national, cross-sectional survey of ACOs (2013-2015) was conducted.
• Survey data were linked to public-use data on ACO performance (2014-2016).
• Characteristics of ACOs using cost reduction measures versus those not were compared, analyzing savings, spending, and visit rates.

Main Results:

• 26% of surveyed ACOs reported using cost reduction measures in specialist compensation.
• ACOs using these measures were more frequently physician-led and served higher-risk patients.
• No significant short-term association was found between using cost reduction measures and ACO savings, outpatient spending, or specialist visit rates.

Conclusions:

• Incentivizing specialists based on cost reduction did not yield significant short-term ACO savings.
• Additional research is necessary to identify optimal methods for engaging specialists in ACO performance improvement efforts.
• The findings suggest that current approaches to specialist compensation in ACOs may require re-evaluation for long-term effectiveness.
