Validity of the I‑FEED classification in assessing postoperative gastrointestinal impairment in patients undergoing elective lumbar spinal surgery with general anesthesia: a prospective observational study
Authors' conclusion
This study contributes preliminary validity evidence for the I-FEED score as a measure for postoperative gastrointestinal impairment after elective lumbar spine surgery.
Study context
- Population
- Adults undergoing elective lumbar spine surgery with GA
- Participants
- 156 adults
- Exposure
- I-FEED categories: normal vs postoperative gastrointestinal intolerance (POGI) vs postoperative gastrointestinal dysfunction (POGD)
- Outcome
- Construct validity of I-FEED category vs LOS, inhospital medical cost, postoperative gastrointestinal medical treatment and non-gastrointestinal complications
- Follow-up
- 4 days after surgery
Methodological detailsconstruct validity hypothesis testing

Main finding
As reported in the abstract
Distribution of I-FEED categories
Observational data: associations, not effects.
Further findings
Rectal laxatives required — POGD vs Normal
P = 0.026
| Outcome | Estimate | P value |
|---|---|---|
| LOSPOGD vs Normal · significantly longer | median difference 1 day | P = 0.049 |
| Inhospital medical costPOGD vs Normal · approximately | difference 500 Taiwanese dollars | P = 0.037 |
Safety
Non-gastrointestinal complications — POGD vs Normal
P = 0.034
