Payment mechanism and GP self-selection: capitation versus fee for service.

Area of Science:

• Health economics
• Healthcare management
• General practice

Background:

• Gatekeeping general practitioners (GPs) play a crucial role in healthcare systems.
• Payment mechanisms significantly influence GP behavior and patient care.
• Understanding the impact of payment choice is vital for optimizing healthcare delivery.

Purpose of the Study:

• To analyze the consequences of allowing GPs to select their payment mechanism.
• To model GP behavior under different payment schemes (capitation, fee-for-service) and self-selection.
• To determine optimal payment strategies based on GP characteristics and referral costs.

Main Methods:

• Economic modeling of GP behavior.
• Analysis of heterogeneous GPs (ability and patient health concern).
• Consideration of different payment schemes: capitation and fee-for-service.

Main Results:

• Fee-for-service is optimal when wasteful referral costs are high, maximizing net patient health.
• Capitation or GP self-selection is optimal when losses from failed referrals of severely ill patients are high.
• GP self-selection is never optimal when considering endogenous effort or competition.

Conclusions:

• GP payment mechanism choice has significant implications for patient health outcomes.
• Optimal payment strategies depend on the specific cost structures and risks within a healthcare system.
• Self-selection of payment mechanisms by GPs is not an optimal strategy in competitive or effort-sensitive environments.
