Enteral nutrition (EN) — delivery of nutrients directly into the gastrointestinal tract via tube — is the preferred nutritional support route for patients with a functional GI tract who cannot meet their needs orally. More than 300,000 patients receive enteral nutrition in U.S. healthcare settings on any given day, spanning ICUs, long-term care facilities, and home health programs. Managing the supply chain for enteral nutrition supplies requires attention to tube types, delivery systems, formula compatibility, and regulatory compliance.
Enteral Access Devices: Tubes and Placement
Nasogastric (NG) Tubes: Inserted through the nose into the stomach, NG tubes are used for short-term feeding (typically <4–6 weeks) and gastric decompression. Available in polyurethane (softer, longer dwell time) and PVC (stiffer, lower cost). French sizes 8–12 are standard for adult feeding; 5–8 Fr for pediatric use. Confirm placement via X-ray before initiating feedings.
Nasojejunal (NJ) and Nasoduodenal Tubes: Passed through the nose into the duodenum or jejunum, these tubes are indicated for patients at high aspiration risk or with gastroparesis. Placement typically requires fluoroscopic or endoscopic guidance.
PEG (Percutaneous Endoscopic Gastrostomy) Tubes: For long-term enteral access (>4–6 weeks), PEG tubes are the standard of care. Placed endoscopically into the stomach and secured externally with a bumper or balloon, PEG tubes enable durable access for patients with dysphagia, neurological conditions, or head and neck cancer. Low-profile "button" PEG devices (e.g., MIC-KEY, Bard Button) are preferred for ambulatory patients.
Jejunostomy (J) Tubes: Deliver formula directly into the jejunum, bypassing the stomach. Indicated post-esophagectomy, Whipple procedure, and other upper GI surgeries.
Enteral Delivery Systems
Enteral formula can be delivered by three methods:
- Gravity/bolus: Formula flows by gravity through a large-bore syringe or drip set. Lowest cost, suitable for gastric feeding in stable patients.
- Continuous pump feeding: An enteral pump delivers formula at a controlled rate over 16–24 hours. Required for jejunal feeding and high-risk patients. Pumps from Abbott (Flexiflo), Kangaroo (Cardinal/Covidien), and Moog (EnteraLite) are widely used.
- Cyclic feeding: Pump feeding over 8–16 hours, typically overnight — allows patients daytime freedom.
Pump-compatible feeding sets are single-use, replaced every 24 hours to prevent microbial contamination. Ensure set compatibility with your pump model before placing orders.
Enteral Formula Categories
Formula selection is a clinical decision driven by patient diagnosis, caloric needs, and GI tolerance. Categories include standard polymeric (intact protein), semi-elemental (partially hydrolyzed), elemental (free amino acids), disease-specific (renal, hepatic, pulmonary, diabetic), and immune-modulating formulas. Formulary standardization — selecting 4–6 core formulas for 80%+ of patients — simplifies procurement and reduces waste from formula hoarding.
Procurement Best Practices
High-volume facilities should negotiate direct contracts with formula manufacturers (Abbott, Nestlé Health Science, Mead Johnson) for formula, and source delivery supplies (tubes, sets, bags, pumps) through a distributor like Healix. Standardizing on a single pump platform reduces set SKU proliferation.
