Does provider variation matter to health plans?

Area of Science:

• Health economics
• Healthcare management
• Behavioral healthcare

Background:

• Provider-level treatment variation can signal either enhanced patient-provider matching or provider uncertainty.
• The response of health plans to this provider-level variation remains largely unexamined.
• Understanding this dynamic is crucial for effective healthcare system management and quality assessment.

Purpose of the Study:

• To investigate how health plans react to variations in treatment patterns among individual healthcare providers.
• To apply portfolio selection models to understand provider choice within a healthcare context.

Main Methods:

• Utilized a model adapted from financial portfolio selection theory.
• Analyzed data from a behavioral healthcare vendor with provider selection oversight.
• Examined the relationship between provider-level treatment variance and health plan responses.

Main Results:

• Found minimal evidence indicating that health plans adjust their behavior based on provider-level treatment variance.
• The study suggests that health plans do not actively manage or respond to the heterogeneity in treatment choices made by individual providers.

Conclusions:

• Health plan responses to provider-level treatment variation are limited.
• The findings imply that current health plan oversight mechanisms may not effectively address or utilize information contained in provider-specific treatment patterns.
