Application of enhanced recovery after surgery in the perioperative period of pediatric enterostomy closure

Table 3 Multivariable linear regression analysis of factors influencing caregiver satisfaction rate and postoperative length of stay

Variable	Caregiver satisfaction rate		Postoperative LOS
	β (95%CI)	P value	β (95%CI)	P value
ERAS group vs TRAD group	0.24 (0.06, 0.42)	0.011	-2.29 (-3.28, -1.30)	< 0.001
Age (continuous, per month)	0.01 (-0.01, 0.02)	0.226	-0.05 (-1.00, -0.01)	0.006
Body weight (continuous, per kg)	-0.02 (-0.07, 0.02)	0.336	0.15 (-0.09, 0.39)	0.222
Operative duration (continuous, per minute)	0 (-0.01, 0.01)	0.650	0.01 (-0.02, 0.03)	0.682
Enterostomy site (ref: Small bowel)	0.11 (-0.09, 0.32)	0.257	0.73 (-0.35, 1.80)	0.181
Postoperative complications (ref: No)	-0.20 (-0.45, 0.05)	0.112	0.94 (-0.42, 2.29)	0.170
Preoperative nutritional status (ref: STAMP score < 4)	-0.03 (-0.25, 0.19)	0.780	1.03 (-0.17, 2.23)	0.091
Anesthetic technique (ref: Alone)	-0.02 (-0.21, 0.18)	0.864	-0.98 (-2.02, 0.06)	0.063
Social support level (ref. Inadequate)	0.11 (-0.19, 0.41)	0.473	-1.22 (-2.86, 0.42)	0.141

Statistical significance was set at P < 0.05. The model is adjusted for age, body weight, operative duration, enterostomy site (small bowel vs colon), postoperative complications (yes vs no), preoperative nutritional status, anesthetic technique, and social support level to control for potential confounding. For continuous variables (age, body weight, operative duration), β coefficients represent the change in caregiver satisfaction rate per 1-unit increase in the variable. CI: Confidence interval; LOS: Length of stay; ERAS: Enhanced recovery after surgery; STAMP: Screening Tool for the Assessment of Malnutrition in Pediatrics; TRAD: Traditional care.
