Impact of Gastrointestinal Panel Implementation on Health Care Utilization and Outcomes [Bacteriology]

The objective of this study was to evaluate the management and health care utilization of patients following GI panel compared with conventional stool testing. We performed a retrospective comparative analysis of 9,402 patients who underwent testing with the FilmArray GI panel from March 2015 through May 2017 and 5,986 patients who underwent conventional stool testing from December 2012 through February 2015. GI panel was positive in 2,746 exams (29.2%) compared with 246 exams (4.1%) with conventional testing. Within 30 days following stool testing, compared with patients who received a conventional stool test, patients who received a GI panel were less likely to undergo any endoscopic procedure (8.4% GI panel versus 9.6% stool culture, P = 0.008) or any abdominal radiology (29.4% GI panel versus 31.7%, P = 0.002). Within 14 days following stool testing, patients who received a GI panel were less likely to be prescribed any antibiotic (36.2% GI panel versus 40.9%, P < 0.001). The implementation of multiplex PCR stool testing was associated with a reduction in the utilization of endoscopy, abdominal radiology, and antibiotic prescribing.
