The purpose of this study was to evaluate the efficacy of a pilot alvimopan stewardship program aimed at intervening to discontinue alvimopan use following GI recovery.MethodsThis was a retrospective, observational study examining the first 5 months of the alvimopan stewardship pilot program. During this initial period, a pharmacy resident assessed whether each patient met criteria for GI recovery, defined as solid food toleration and first bowel movement or flatus. If a patient met the criteria for GI recovery, the resident intervened and recommended that the primary team discontinue alvimopan. Primary outcomes were the percentage of patients with alvimopan continued past GI recovery and the percentage of patients for whom alvimopan ordered past GI recovery was discontinued following intervention by stewardship. Secondary outcomes included the percentage of accepted recommendations to discontinue alvimopan following GI recovery and the number of alvimopan doses ordered following GI recovery.ResultsIn total, 73 patients were included in the study analysis, all of whom underwent abdominal and/or urologic surgery. Alvimopan was ordered to be administered in 35.6% (26/73) of patients after GI recovery. The stewardship program intervened and recommended discontinuation on 50% (13/26) of the alvimopan doses ordered past GI recovery. Recommendations were accepted by the primary team for 92.3% (12/13) of the patients. A total of 51 doses of alvimopan were ordered for administration past GI recovery, with an average of 2 doses per patient.ConclusionA pilot pharmacy-driven alvimopan stewardship program was able to identify and intervene on alvimopan orders continued past GI recovery. Interventions decreasing alvimopan use past GI recovery could be of benefit by minimizing potential risk and decreasing potential costs without a negative impact on patient outcomes.
