Abstract
Objective: To study the cost-effectiveness of an early postoperative feeding protocol for patients undergoing bowel resections. Design: A nonrandomized, prospective, clinical trial. Surgeons elected to participate in the treatment arm before the study's outset. Subjects/setting: Treatment (n = 66) and control (n = 159) patients were admitted to a nonprofit general teaching hospital in the Texas Medical Center for similar diagnoses and subsequent bowel resections during an 18-month period. Intervention: Treatment patients who met specific inclusion criteria had a jejunal feeding tube placed during surgery. Tube feedings were initiated within 12 hours after surgery. Control patients who met the same inclusion criteria received usual care. Outcomes: A successful outcome was defined as a patient developing no postoperative infection. The average cost of a nosocomial infection is presented. Variable direct and total costs (fixed plus variable) are compared between patient groups. Statistical Analysis: Mean cost was adjusted for rate of success in each patient group according to an analytic model. The mean cost difference between groups was analyzed by independent-samples t tests. Nonparametric Mann-Whitney rank sum tests were used to determine the cost significance of a nosocomial infection. Results: The average variable direct cost savings per successful treatment patient was $1,531, which required an additional variable cost of $108.30 for the dietitian's time. The protocol resulted in a total cost savings of $4,450 per success in the treatment group. Conclusion: An early postoperative enteral feeding protocol as part of an outcomes management program for patients undergoing bowel resection is cost-effective. (J Am Diet Assoc 99:802–807, 1999)
