ABSTRACT
While more clinicians have begun ordering multitarget stool DNA (mt-sDNA) testing due to the COVID-19 pandemic, adherence to guidelines on mt-sDNA and rates of subsequent follow-up testing has not been well studied. Of the 56 patients who underwent colonoscopy at our institution, most had documentation of a high-quality colonoscopy, defined as adequate prep (84%), cecal intubation (93%), visualization of the appendiceal orifice and ileocecal valve (94%), and right colon retroflexion (83%). Appropriateness, shared decision making, and screening results in patients undergoing mt-sDNA testing Appropriateness of Order Order was appropriate (%) 685 (86) Inappropriate due to patient age < 45 (%) 2 (0) Inappropriate due to patient age > 85 (%) 10 (1) Inappropriate because CRC screening was repeated too quickly (%) 29 (4) Inappropriate as patient is at higher than normal risk for CRC (%) 79 (12) Other condition (eg. abnormal surgical anatomy) (%) 7 (1) Shared Decision Making Documentation of shared decision making (%) 488 (62) mt-sDNA was ordered because patient declined colonoscopy (%) 302 (62) Screening Results Completed mt-sDNA screening (%) 483 (61) Median time to mt-sDNA completion, days (IQR) 25 (17-43) Positive (%) 74 (15) Diagnostic colonoscopy was ordered (%) 73 (99) Completed colonoscopy (%) 59 (80) Completed colonoscopy at our institution 56 (76) Median time to colonoscopy, days (IQR) 53 (27-95) Adequate bowel preparation (%) 47 (84) Documentation of cecal intubation (%) 55 (98) Documentation of appendiceal orifice and IC valve visualization (%) 48 (94) Documentation of right colon retroflexion (%) 44 (83) Advanced adenoma found on colonoscopy (%) 16 (29) Other adenoma or sessile polyp found on colonoscopy (%) 19 (34) Negative (%) 409 (85) Documentation of a 3-year follow-up screening recommendation (%) 369 (80)
