📊 Colonoscopy Quality Metrics: What They Mean for YOU

Not all colonoscopies are created equal. GI societies define quality benchmarks that help ensure colonoscopies are thorough, safe, and effective at preventing colon cancer. Here’s what those numbers really mean — in plain language 👇

🔍 What doctors track behind the scenes:
• Cecal intubation rate – Did we reach the very beginning of the colon? (Goal: >95%)
• Withdrawal time – How carefully the doctor looked while coming out (Goal: >8-9 minutes)
• Adenoma Detection Rate (ADR) – How often precancerous polyps are found (higher = better)
• SSL Detection Rate (SSLDR) – How often we detected subtle flat precancerous polyps that can be harder to see (higher = better)

✅ Updated 2025 GI Society Goals vs. Our Results:
• Cecal intubation: 99.9% (Goal >95%)
• Average withdrawal time: 15.4 minutes (Goal >8-9 minutes)
• Female ADR: 40.3% (Goal >30%)
• Male ADR: 56.3% (Goal >40%)
• SSLDR: 18.7% (Goal >6%)

💡 Why this matters to patients:
Higher detection rates mean more precancerous polyps removed, fewer missed lesions, and better protection against colon cancer — especially between screenings.

📣 Patients: you have the right to ask about quality.
The American Society for Gastrointestinal Endoscopy encourages patients to ask their doctor about these exact metrics when choosing where to have a screening colonoscopy.
📖 ASGE Patient Education: “What Patients Should Know About Colonoscopy Quality” (Gastrointestinal Endoscopy Journal / ASGE.org)

🏆 We’re proud of our team’s commitment to exceeding national benchmarks — because quality isn’t a statistic, it’s patient care.

If you or someone you know are due for colon cancer screening (age over 45, family history of polyps or cancer, personal history of polyps), please call our office at 224.407.4400 or email info@compgihealth.com to schedule your procedure in our lovely environment with our exceptional quality.
