Impact of a pay-for-performance program on low performing physicians.

Area of Science:

• Health Services Research
• Healthcare Quality Improvement
• Physician Performance Measurement

Background:

• Previous studies indicated that physicians with the lowest performance in pay-for-performance (P4P) programs showed the most significant improvement.
• However, it remained uncertain whether these improvements would occur independently of P4P or be sustainable over time.

Purpose of the Study:

• To investigate the long-term impact of P4P initiatives on low-performing physicians within a Preferred Provider Organization (PPO) over a four-year period.
• To assess the sustainability of quality improvements driven by P4P programs.

Main Methods:

• Utilized administrative claims data from two PPO health plans: one in Hawaii with a P4P program and a comparable plan in the South without P4P.
• Employed a difference-in-differences model to compare changes in quality scores between the two groups.
• Evaluated performance on preventive measures, a heart failure measure, and HbA1c testing.

Main Results:

• Physicians in the P4P program demonstrated significant quality improvements compared to those in the non-P4P plan.
• The positive effects of the P4P program on physician quality improvement became more pronounced in the third and fourth years.
• Evidence suggests that P4P can incentivize sustained quality enhancement among low performers.

Conclusions:

• Pay-for-performance programs show potential in motivating low-performing physicians to improve the quality of care.
• Sustained quality improvements driven by P4P may require several years of program implementation to be fully realized.
• P4P appears to be an effective strategy for enhancing and maintaining healthcare quality among underperforming physicians.
