Objective: To examine the impact of alvimopan on outcomes and costs in a rigorous enhanced recovery colorectal surgery protocol.
Background: Postoperative ileus remains a major source of morbidity and costs in colorectal surgery. Alvimopan has been shown to reduce incidence of postoperative ileus in enhanced recovery colorectal surgery; however, data are equivocal regarding its benefit in reducing length of stay and costs.
Methods: Patients undergoing major elective enhanced recovery colorectal surgery were identified from a prospectively-collected database (2010-2013). Multivariable analyses were employed to compare outcomes and hospital costs among patients who had alvimopan versus no alvimopan by adjusting for demographic, clinical, and treatment characteristics.
Results: A total of 660 patients were included; 197 patients received alvimopan and 463 patients had no alvimopan. In unadjusted analysis, the alvimopan group had a faster return of bowel function, shorter length of stay, and lower rates of ileus, Foley re-insertion, and urinary tract infection (all P < 0.01). After adjustment, alvimopan was associated with a faster return of bowel function by 0.6 day (P = 0.0006), and lower incidence of postoperative ileus (odds ratio 0.23, P = 0.0002). With adjustment, alvimopan was associated with a shorter length of stay by 1.6 days (P = 0.002), and a hospital cost savings of $1492 per patient (P = 0.01).
Conclusions: Alvimopan administration as an element of enhanced recovery colorectal surgery is associated with faster return of bowel function, lower incidence of postoperative ileus, shorter hospitalization, and a significant cost savings. These results suggest that alvitnopan is cost-effective in the setting of enhanced recovery colorectal surgery protocols, and should therefore be considered in these programs.
