Daily enteral feeding practice on the ICU: attainment of goals and interfering factors

Table 4 Multivariate analysis of patient and feeding factors for the success of feeding intake

Feeding and patient factors	OR	95% CI
Duodenal tube*	1.44	1.21–1.73
Needle catheter jejunostomy*	3.32	2.05–5.38
Semi-elemental formula (100/4)^†	3.02	1.75–5.21
Standard/Energy⁺ formula (125/5)^†	1.62	1.31–1.99
Mechanical ventilation	1.63	1.27–2.09
Contrast via tube to prepare for CT scan	0.34	0.22–0.55
Gastric retention (<200 ml/>200 ml)	1.51	1.29–1.78
Cisapride	0.83	0.71–0.96
TISS category per patient day	0.84	0.74–0.96
Elective admission	0.81	0.69–0.94
Length of stay in intensive care unit	1.53	1.28–1.82

Success of feeding intake was defined as feeding of more than 90% of the prescribed formula. CI, confidence interval; CT, computed tomography; OR, odds ratio; TISS, Therapeutic Intervention Score System. An odds ratio of more than 1 indicates improved success of feeding. *Compared with reference gastric tube (odds ratio of 1). ^†Compared with the reference standard feeding (odds ratio of 1); numbers in parentheses are kcal/protein.
