A81 OPTIMIZING THE INDICATIONS FOR BILIARY STENT PLACEMENT IN PATIENTS WITH CBD STONES: A QUALITY IMPROVEMENT INITIATIVE TO ENHANCE PATIENT CARE AND REDUCE HEALTHCARE RESOURCE UTILIZATION

Abstract Background A retrospective chart audit was performed to review biliary stent utilization from January 2020 to 2021 at the University of Alberta Hospital (UAH). Inappropriate stent usage was identified in 16% of patients with common bile duct (CBD) stones presenting for endoscopic retrograde cholangiopancreatography (ERCP). To improve this clinical practice, a quality improvement (QI) initiative was developed and completed. Purpose To reduce the number of inappropriately inserted biliary stents in patients with CBD stones. Method The results of the chart audit (pre-intervention) were shared with the ERCP group. The QI intervention was to align biliary stent insertion in accordance with published guidelines. A chart audit (post-intervention) was then performed on all ERCPs from July, 2021 to June, 2022. The indication for biliary stent insertion was assessed independently by two blinded reviewers. Result(s) A total of 661 patients (337 F) with mean age of 59±19 years (range 12-98 years) underwent 885 ERCPs during this post-intervention period. Of the 661 patients, 384 (58%) were referred for CBD stones. A total of 192 biliary stents (105 plastic, 85 metal) were placed during the first ERCP (192/661, 29%), as compared to the pre-intervention year (223/598, 37%, p=ns). However, only 13/192 stents (7%) were placed not in accordance with published guidelines (kappa=0.53), compared with 63/223 (28%) in the pre-intervention year (p<0.0001). This accounts for a 75% reduction in overall unnecessary stent placement. This reduction was mainly seen in the CBD stone subgroup, where there was an 88% reduction in inappropriate biliary stent placement compared to the pre-intervention year (8/384, 2% vs. 61/376, 16%, p<0.0001). Image Conclusion(s) Education to align practice in accordance with published guidelines has demonstrated a significant improvement in biliary stent insertion during ERCP in patients with CBD stones. This has resulted in significantly fewer inappropriate stent placements, a reduction in unnecessary follow-up ERCPs, and an overall saving of healthcare resources.
