About

The primary objective of this study is to determine to what extent hunger provocation, via rapid weaning from enteral feedings, is acceptable and feasible and to evaluate the effect of this intervention when used in an intensive multidisciplinary feeding intervention (IMFI) model of treatment (standard care), for individuals with Avoidant Food Intake Disorder (ARFID) who are dependent on enteral feedings to meet their daily caloric needs.

Full description

The recognized standard of care for children dependent on feeding tubes is intensive multidisciplinary feeding intervention (IMFI) involving a professional team that includes psychologists, physicians, nurse practitioners, registered dietitian nutritionists, and speech-language pathologists/occupational therapists working together in inpatient or day hospital settings. A meta-analysis of 11 studies involving intensive, multidisciplinary intervention reported that 71% (95% CI, 54%-83%) of 454 patients successfully weaned from feeding tube dependence at discharge from inpatient or intensive day treatment programs. Treatment gains were maintained following discharge, with 80% (95% CI, 66%-89%) of 414 patients successfully weaned from tube feedings at last follow-up. The most common treatment approaches documented by the meta-analysis involved behavioral intervention and tube weaning (hunger manipulation - evoking a state of hunger to encourage oral consumption by rapidly weaning from the tube). The review highlighted the lack of consensus among clinicians and researchers regarding the criteria for, rate of, and timing of weaning from enteral feedings.

As a result, the authors concluded that the relative contribution of aggressive tube weaning as a standalone or adjunctive therapy to behavioral intervention remains uncertain.

The primary objective of this study is to determine to what extent hunger provocation, via rapid weaning from enteral feedings, is acceptable and feasible and to evaluate the effect of this intervention when used as an adjunct to our standard model of behavioral intervention within the study team's IMFI program, for individuals with Avoidant Food Intake Disorder (ARFID) who are dependent on enteral feedings to meet their daily caloric needs.

Enrollment: 16 patients

Inclusion criteria

• Be between the ages of 18 months and 6 years of age;
• Present with dependence on enteral feeding for at least 80% of their daily caloric needs; - Have some prior experience consuming food orally;
• Demonstrate safe and functional swallowing;
• Present without neuromuscular conditions who are non-ambulatory (such as cerebral palsy);

16 participants in 2 patient groups

Intensive Multidisciplinary Intervention (Standard Care)

Active Comparator group

Description:

Children with a history of chronic food refusal will be randomized to receive the standard of care. The standard of care for tube wean is to accomplish the balance between enteral supplementation and oral intake, the tube feeding regimen will follow the schedule of therapeutic meals (e.g., mid-day supplementation occurs after morning therapeutic meals).

Treatment:

Behavioral: Intensive Multidisciplinary Feeding Intervention (IMFI)-Standard of Care

Intensive Multidisciplinary Intervention (Standard Care) + Hunger provocation (Rapid Tube Wean)

Experimental group

Description:

Children with a history of chronic food refusal will be randomized to receive the experimental arm that combines standard care with rapid tube wean. All schedules and documents will be updated accordingly. After the 50% tube wean cut, the dietitian will use regular tube wean sheet to provide credit for oral intake for remainder of admission.

Treatment:

Behavioral: Intensive Multidisciplinary Feeding Intervention (IMFI) standard of care + rapid tube weaning
