Abstract
BackgroundAlvimopan has been shown to shorten time to return of bowel function (RBF), thereby decreasing length of stay (LOS). The aim of this study was to assess the clinical significance of this effect on actual practice. MetjodsA retrospective and prospective study of elective bowel resection patients was performed. Surgeons were assigned to alvimopan users (treatment) or nonusers (control). Primary outcome measures included LOS, RBF, and total hospital cost (THC). ResultsMean RBF was 2.93 ± 1.22 days in the treatment group and 4.22 ± 1.81 days in the control group (P < .001). Mean LOS was 7 ± 2.6 days in the treatment group and 7.2 ± 2.2 days in the control group. Mean THC was $7,584 ± $4,770 in the treatment group and $7,310 ± $5,471 in the control group (P > .81). LOS decreased by 2.5 days compared with the historical controls, independent of alvimopan use. ConclusionsAlvimopan improved RBF but not LOS or THC. Reductions in average LOS of 1 day for ≤6 doses and 2 days if patients received >6 doses were needed to decrease THC.
