Surgical quality refers to the consistent delivery of safe, effective, and evidence-based care throughout the perioperative process. It encompasses technical performance, decision-making, complication prevention, and postoperative outcomes.

Monitoring surgical quality requires measurable indicators such as:

• Complication rates
• Procedure success rates
• Operative time
• Infection or reintervention rates
• Patient-reported outcomes

CUSUM analysis enhances surgical quality assessment by:

• Providing real-time performance feedback.
• Identifying deviations from expected standards.
• Supporting root cause analysis when outcomes deteriorate.
• Enabling data-driven credentialing and quality assurance.

It complements traditional metrics by focusing on individual performance over time, rather than aggregated outcomes alone.

When integrated across a department or institution, CUSUM can:

• Promote a culture of continuous improvement.
• Detect systemic issues before they escalate.
• Objectively monitor training effectiveness.
• Support hospital accreditation and external audit processes.

Ultimately, surgical quality is not only about reducing complications, but about creating a reliable and transparent system that fosters learning, safety, and patient trust.
