17.2 Interdisciplinary Coordination & Transitions of Care

The Pediatric Interdisciplinary Team: Who Owns What

Pediatric nutrition care is team care, and the CSP exam tests role boundaries relentlessly. The high-yield roster:

• Registered dietitian (RD): nutrition assessment, diet/enteral/parenteral prescription, nutrient adequacy, growth monitoring, nutrition education
• Physician / nurse practitioner / physician assistant: medical diagnosis, orders, overall plan of care
• Registered nurse: medication and tube-feeding administration, line care, intake/output, family teaching reinforcement
• Speech-language pathologist (SLP): swallow safety (including instrumental studies such as the videofluoroscopic swallow study / modified barium swallow and the fiberoptic endoscopic evaluation of swallowing), oral-motor structure and function, feeding-skill development
• Occupational therapist (OT): positioning and seating, sensory processing, self-feeding and utensil skills, adaptive equipment
• Physical therapist (PT): gross motor function, mobility, energy-expenditure considerations
• Pharmacist: parenteral nutrition compounding, drug–nutrient interactions, compatibility
• Social worker / case manager: insurance, WIC/SNAP enrollment, home-care and supply coordination, psychosocial barriers
• Psychologist / behavioral therapist: feeding aversion, avoidant/restrictive food intake disorder (ARFID), adherence
• Lactation consultant (IBCLC): breastfeeding support
• Child life specialist / teacher: developmental support and school re-entry

Classic trap: a question describes a child coughing with thin liquids and asks who should evaluate the swallow — the answer is the SLP (with instrumental assessment), while the RD modifies the diet prescription and ensures adequate nutrition within the recommended texture. The RD does not perform swallow studies, and the SLP does not calculate calorie needs.

Transition 1: NICU to Home

Discharge readiness for the preterm infant is a cluster of competencies, not a date: sustained weight gain (roughly 15–30 g/day) on full oral feeds, maintenance of thermoregulation in an open crib, and cardiorespiratory stability — typically achieved around 36–37 weeks postmenstrual age, though some infants go home earlier and many later. Before discharge, preterm infants (generally those born <37 weeks) undergo a car seat tolerance test (car seat challenge): a monitored period, often 90–120 minutes, seated in their own car seat to screen for apnea, bradycardia, or desaturation in the semi-reclined position.

The nutrition-specific discharge bundle includes:

• A written feeding plan specifying formula concentration or human milk fortification (preterm infants frequently discharge on 22 kcal/oz or fortified human milk) with exact mixing instructions the caregiver has demonstrated back
• Supply chain confirmation — formula or fortifier source, pump and kit for expressed milk, any specialty formula authorization (many require prior authorization through insurance or WIC)
• Vitamin D and iron supplementation orders for breastfed preterm infants
• Scheduled follow-up: pediatrician within days, and neonatal/nutrition follow-up with growth-velocity targets clearly handed off

Trap: discharging a preterm infant on unfortified term formula or standard breastfeeding alone without a fortification plan risks post-discharge growth faltering — post-discharge nutrition is an active prescription, not a default.

Transition 2: Hospital to School (and Back Again)

Children returning to school with feeding tubes, texture-modified diets, diabetes regimens, or severe food allergies need a formalized plan, because school staff are not clinicians. The legal vehicles:

• Section 504 plan (Rehabilitation Act of 1973): accommodations for a disability that limits a major life activity — eating qualifies. Used for tube feeding at school, carbohydrate counting with insulin, allergen-safe meals, extended meal time.
• Individualized Education Program (IEP) under the Individuals with Disabilities Education Act (IDEA): when the child needs specialized instruction or related services; feeding and nutrition services can be written in as related services.
• Individualized Health Care Plan / Emergency Care Plan: the school nurse's operational document covering who, what, when, and escalation steps (e.g., glucagon administration, G-tube troubleshooting, epinephrine).

The RD's role is to write the nutrition component — exact formula, rate, flush volumes, texture level, carb counts, safe substitutions — in language a trained layperson can follow, and to coordinate with the school nurse on delegation and staff training. USDA school meal programs must provide meal accommodations at no extra charge when a disability restricts the diet, supported by a medical statement.

Transition 3: Pediatric to Adult Care

Transition is the planned process; transfer is the event. Best practice (aligned with the American Academy of Pediatrics and the Got Transition Six Core Elements) starts planning around age 12–14 with self-management skill-building — the teen learns to mix their own formula, order supplies, describe their diagnosis, and keep their own appointments — with transfer typically between ages 18 and 21. Conditions with lifelong nutrition therapy are the highest-risk for being lost: phenylketonuria (diet for life), cystic fibrosis, type 1 diabetes, inflammatory bowel disease, and transplant recipients. A successful handoff includes a written transition plan, a portable medical summary, identified adult providers, and a confirmed first adult appointment. The classic failure — and exam trap — is abrupt discharge at 18 with no adult team identified, which predictably leads to metabolic decompensation or nutrition relapse.
