BEST PRACTICES
& QUALITY MEASURES

Region’s leader in colorectal cancer screening and member of the Oregon Cancer Alliance

Adenoma detection rate for finding precancerous colon polyps during colonoscopy is well above recommended guidelines: National benchmark for males is 30 percent; our rate is 56.3 percent. National benchmark for females is 20 percent; our rate is 36.7 percent.

Dr. Jonathan Gonenne, who performs EUS, is a recipient of the Swallows of Hope Award by Oregon Cancer Alliance for going above and beyond to provide outstanding care for cancer patients

Offers 24/7 patient phone line for emergency situations and other GI-related issues, such as prep questions, medication refills, severe symptoms, lab results, etc., to minimize urgent care and ER visits

An assigned urgent care provider (rotates weekly) takes urgent, in-clinic consults from referring providers to minimize ER visits and/or hospital admissions.

Endoscopy center/ambulatory surgical center (ASC) uses propofol sedation, administered by an anesthesiologist, to avoid hospital SPA use (total cost savings for the procedure)

Endoscopy center/ambulatory surgical center (ASC) performs Bravo pH studies to avoid hospital SPA use (total cost savings for the procedure)
