ACS verification enhances safety and effectiveness across multiple surgical outcomes.

• 61% of outcomes improved with ACS verification; 34% showed no difference.
• Significant gains in safety (p=0.0024), effectiveness (p<0.0001), equity (p=0.001), and patient-centeredness (p<0.0001).

Consider ACS verification as a pivotal strategy for quality improvement, particularly in safety-focused practices.

• Efficiency and timeliness outcomes were less consistent and warrant further investigation.
