Does pay-for-performance influence the quality of care?

Area of Science:

• Health Services Research
• Health Economics
• Quality Improvement

Background:

• Pay-for-performance (PFP) programs are increasingly used to incentivize quality improvements in healthcare.
• These programs aim to enhance clinical quality of care markers in ambulatory settings.
• Physician groups and individual physicians are the primary targets of these PFP initiatives.

Purpose of the Study:

• To systematically review and summarize existing studies on pay-for-performance programs.
• To evaluate the impact of PFP programs on clinical quality of care markers.
• To identify factors influencing the effectiveness of PFP programs in ambulatory care.

Main Methods:

• Conducted a literature review of randomized controlled trials (RCTs) and nonrandomized studies.
• Included studies focusing on PFP programs targeting physician groups or individual physicians.
• Analyzed results based on study design, quality measures, incentives, and patient/provider characteristics.

Main Results:

• Seven RCTs and 15 nonrandomized studies were reviewed.
• Less than half of RCTs demonstrated positive outcomes; most nonrandomized studies showed positive or mixed results.
• Methodological limitations, including small sample sizes and bias, were common across studies.
• Asthma quality markers showed mixed results in three nonrandomized studies.

Conclusions:

• PFP programs show potential for improving quality markers, but effectiveness is not consistent.
• Study designs often lack the rigor to definitively attribute improvements solely to PFP incentives.
• Further high-quality research is needed to ascertain the isolated effectiveness, optimal conditions, and cost-effectiveness of PFP incentives.
