Does the frequency of pay-for-performance payment matter?--Experience from a randomized trial

Area of Science:

• Health Services Research
• Medical Economics
• Physician Payment Models

Background:

• Pay-for-performance (P4P) programs incentivize healthcare providers to improve quality of care.
• Understanding the optimal design of P4P programs, including incentive payment frequency, is crucial for maximizing their effectiveness.
• Physician motivation and response to financial incentives may be influenced by how frequently these incentives are delivered.

Purpose of the Study:

• To investigate the impact of varying incentive payment frequencies on the quality performance of physicians within a P4P program.
• To compare the effects of quarterly bonus payments versus a single year-end bonus on physician adherence to quality measures.
• To determine if the timing of financial rewards influences physician behavior in a P4P setting.

Main Methods:

• A randomized controlled trial was conducted within a multispecialty physician group practice.
• Primary care physicians (n=179) were assigned to receive incentive payments either quarterly or annually, with a maximum annual bonus of $5,000.
• Quality measure scores were extracted from electronic health records and compared between the two payment frequency groups over four quarters.

Main Results:

• No statistically significant difference was observed in the average quality measure scores between physicians receiving quarterly versus annual incentive payments.
• The total bonus amount earned by physicians did not differ based on the frequency of payment.
• Physician engagement with quality improvement initiatives, as measured by quality scores, remained consistent regardless of payment schedule.

Conclusions:

• The frequency of incentive payment distribution does not appear to affect physician performance on quality measures in a P4P program with a modest bonus cap.
• These findings suggest that program administrators may have flexibility in choosing payment schedules without compromising quality outcomes.
• Further research could explore the effects of different bonus amounts or other program designs on physician response to P4P initiatives.
