Validity of the I-FEED score for postoperative gastrointestinal function in patients undergoing colorectal surgery

摘要: Postoperative ileus (POI) is common after gastrointestinal surgery and associated with significant morbidity costs. However, POI poorly defined. The I-FEED score a novel outcome measure for POI, developed by expert consensus. It contains five elements (intake, response to nausea treatment, emesis, exam, duration, each scored 0, 1, or 3 points) classifies patients into normal, postoperative intolerance (POGI), dysfunction (POGD). it has not yet been validated in clinical context. objective was provide validity evidence the construct of undergoing colorectal surgery. Data previously collected from trial investigating impact different perioperative fluid management strategies on primary elective laparoscopic colectomy (2013–2015) were analyzed. Patients managed longstanding Enhanced Recovery program (expected length stay (LOS): 3 days). Daily scores generated (normal 0–2, POGI 3–5, POGD 6+ up hospital discharge day 7. Validity assessed testing hypotheses that higher (1) longer time GI3 (tolerating diet + flatus/bowel movement), (2) LOS (> 3 days vs shorter), (3) complications without, (4) poorer recovery (measured Quality Recovery-9 questionnaire). A total 128 included analysis (mean age 61.7 years (SD 15.2), 57% male, 71% malignancy, 39.1% rectal resection). Median 4 days [IQR3–5], 32% experienced in-hospital morbidity. Overall, 48% categorized as 22% POGI, 30% POGD. data supported all 4 hypotheses. This study contributes preliminary
