The efficacy of multidisciplinary inpatient and outpatient treatment for transitioning children with severe pediatric feeding disorders from gastrostomy tube dependency to oral nutrition was investigated utilizing caloric and fluid intakes as an outcome measure. The study involved 29 children ages 12 months to 5 years of age with gastrostomy tube dependency. Treatments were provided by speech therapists, occupational therapist, dietician and psychologist for a 30 day period. Four treatment groups were evaluated and average intakes compared at 4 observation periods including pretreatment, initiation of treatment, completion of treatment at 30 days and 4 month follow-up. Children receiving inpatient treatment for feeding disorders evidenced significant differences in oral caloric intake from pretreatment to discharge than outpatient treatment (p < .01) and wait list control group (p = .04). Oral caloric intake from discharge to 4 month follow up yielded no significant differences indicating treatment gains were maintained. Change in environment and caretaker showed a significant effect for the inpatient group (d = 1.89). Effects of treatment by age and weight at 4 month follow up were also analyzed.
