Implementation of malignant bowel obstruction multidisciplinary case conferences (MCCs) to improve clinical decision making in malignant bowel obstruction (MBO) in gynecologic oncology.

Abstract

e18322 Background: Though patients (pts) with gynecological cancer are at higher risk of MBO, clinical management is not well defined. We implemented a coordinated team approach to evaluate MBO at Princess Margaret Cancer Centre. The Princess Margaret Cancer Centre inter-professional MBO management program includes nurse led ambulatory symptom management, inpatient treatment algorithm, patient directed bowel management education & MCCs. This study evaluates the utility of MBO MCC on clinical decision making in gynecologic oncology. Methods: Monthly MBO MCCs are conducted to discuss complex clinical management issues. A clinical summary is presented prior to the discussion with each case incorporating radiology review followed by interdisciplinary discussion. In this study, the initial management plan was compared to post-MCC consensus. A change in plan was defined as a consensus plan different from the pre-MCC plan or no definite plan prior to MCC. Barriers to implementation of the consensus were analyzed. Results: From December 2016 to November 2018, 90 pts were discussed in 22 MCCs. Of these, 60 had high grade serous ovarian carcinoma (67%) & 64 had small bowel obstruction (71%). Discussion in MCCs lead to a change in management plan in 49 cases(54%). These changes included recommendations for palliative surgery (25%) or radiation (10%), interventional radiology (23%), pharmacologic management alone (14%), imaging studies (4%) & total parenteral nutrition (TPN) (4%). Chemotherapy continuation, break or regimen changes were recommended in 20%. MCC consensus plan could not be implemented in 11 cases (23%). The barriers were refusal of surgery (8%), interventional radiology procedures (2%), TPN (4%) by patients, functional decline (6%) & inability to create a colostomy due to dense adhesions (2%). During MCC referrals to the dietitian & palliative care team were planned for 16 (18%) & 22 (24%) pts respectively. Conclusions: Interdisciplinary MBO MCCs have a significant impact on decision making in complex MBO cases. Radiology review & group discussion facilitates greater clarity in formulation of a management plan.
