[Economic Evaluation of Integrated Care Systems - Scientific Standard Specifications, Challenges, Best Practice...

Area of Science:

• Health economics
• Healthcare management
• Integrated care

Background:

• Transparency in the economic performance of integrated care systems (IV) is essential for their acceptance and development.
• Current evaluation methods are diverse and often not openly discussed due to proprietary business models.

Purpose of the Study:

• To develop a generic, standardized model for measuring the economic performance of IV interventions.
• To address the need for transparent and reliable economic evaluation methods in integrated care.

Main Methods:

• A catalogue of five quality criteria was used to analyze various evaluation methods, including uncontrolled before-after studies, control group-based approaches, and regression models.
• A best practice model was proposed based on the analysis of existing methods.

Main Results:

• A regression model based on the German morbidity-based risk structure equalization scheme (MorbiRSA) demonstrates advantages in reliability, transparency, and resource efficiency compared to other methods.
• The proposed Population-oriented morbidity adjusted margin improvement model (P-DBV(MRSA)) incorporates adaptations to address criticisms of the MorbiRSA-based model.
• While RCTs and difference-in-difference approaches offer higher validity, their real-world feasibility is limited by economic and practical constraints.

Conclusions:

• The P-DBV(MRSA) approach is proposed as a standardized best practice model for the economic evaluation of integrated care systems.
• A balanced, quality-oriented performance measurement system should complement economic evaluations to prevent short-term cost-cutting at the expense of quality.
