Surpassing benchmarks

At GIA, our hallmark is performance-based quality care. Our quality assurance and performance improvement programs provide measurable outcomes, allowing us to continually track performance quality and provide the best possible service.

An adenoma is a precancerous colon polyp as opposed to a benign poly. The American Society for Gastrointestinal Endoscopy sets the national standards for GI practices in detection of adenomas. This national goal is to detect and remove adenomas in 25% of men and women combined. Gastrointestinal Associates consistently surpasses that goal.
