Understanding the Need for a Nutrition Support Team
For many years, the crucial role of nutrition in patient recovery was often overlooked, a problem described as the “skeleton in the hospital closet”. Malnutrition can lead to a host of adverse consequences, including poor wound healing, increased risk of infection, longer hospital stays, and higher mortality rates. In response to this, hospitals established Nutrition Support Teams (NSTs) to provide focused, expert care for patients with complex nutritional needs, such as those with intestinal failure, undergoing major surgery, or in intensive care units. These teams bring together diverse medical expertise to ensure that patients receive safe, effective, and evidence-based nutritional therapy. The core function of a nutrition support team is not only to provide nutrients but to manage the entire process, from initial screening to discharge planning.
The Multidisciplinary Composition of the NST
A nutrition support team operates most effectively when it functions as a truly collaborative, multidisciplinary unit. A typical core team includes the following professionals, though the exact composition can vary by institution:
- Physician: The team leader, who typically has a specialty in gastroenterology, surgery, or critical care, and is responsible for the overall medical management, diagnosis, and prescription of the nutritional support.
- Registered Dietitian Nutritionist (RDN): Conducts comprehensive nutritional assessments, calculates patient requirements, designs the feeding regimen, and monitors the patient’s response to the nutrition plan.
- Nutrition Support Nurse: A specialist nurse who manages and educates on the safe use of feeding tubes or central intravenous catheters, monitors for complications, and coordinates patient care.
- Pharmacist: Ensures the safety and appropriate composition of parenteral nutrition solutions, advises on compatibility issues, and manages any drug-nutrient interactions.
Other specialists, such as social workers, speech and language therapists, and psychologists, may also be involved to provide holistic care, particularly for complex cases or long-term patients.
Core Functions and Operational Tasks
The function of a nutrition support team can be broken down into several key operational tasks that ensure comprehensive patient care:
- Nutritional Screening and Assessment: A foundational task is to screen all hospitalized patients within a set time frame (e.g., 24-48 hours) to identify those at nutritional risk using validated tools like the NRS-2002. For high-risk patients, a full nutritional assessment is performed to determine the severity and specific needs.
- Therapeutic Planning and Implementation: The team designs and initiates a personalized nutrition care plan, selecting the most appropriate feeding route (oral, enteral, or parenteral) and the specific feeding formula or solution. They ensure timely and adequate provision of nutrients.
- Ongoing Monitoring and Evaluation: Regular monitoring is critical to track the patient's response, manage potential metabolic and mechanical complications, and adjust the nutritional therapy as needed. This includes monitoring lab results, weight, fluid balance, and evaluating feeding tolerance.
- Education and Training: The team plays a vital educational role, training ward staff, patients, and family members on the proper administration and care associated with nutritional support. This improves compliance and patient safety.
- Quality Assurance and Research: By regularly auditing practices and patient outcomes, NSTs can identify areas for improvement and maintain high standards of care. Many teams also engage in clinical research to advance the field of nutritional therapy.
Impact on Patient Outcomes and Cost
Evidence shows that the intervention of a nutrition support team significantly improves patient outcomes and demonstrates substantial cost-effectiveness for hospitals. This is achieved by reducing complications, decreasing hospital length of stay, and ensuring that nutritional support is used appropriately.
| Aspect of Care | Without Nutrition Support Team | With Nutrition Support Team |
|---|---|---|
| Malnutrition Prevalence | Often unrecognized and untreated; can increase during stay. | Identified early through screening; managed proactively. |
| Complications | Higher rates of catheter-related sepsis, metabolic issues, and mechanical problems. | Significantly reduced incidence of complications due to standardized protocols and expert monitoring. |
| Length of Hospital Stay | Often longer due to delayed recovery and higher complication rates. | Reduced duration of hospitalization and lower readmission rates reported. |
| Cost-Effectiveness | Higher costs from extended stays, increased complications, and wasted supplies. | Significant cost savings by avoiding unnecessary treatments, reducing waste, and preventing costly complications. |
| Adherence to Protocols | Inconsistent and often non-standardized nutritional care. | High compliance rates due to clear protocols, education, and team expertise. |
The Role in Transitional Care
The function of a nutrition support team extends beyond inpatient care, playing a pivotal role in transitioning patients to home-based nutritional support when needed. For patients on long-term enteral or parenteral nutrition, the NST provides crucial education and logistical coordination with home care agencies. They ensure the patient and caregivers are fully trained in managing the feeding equipment, recognizing issues, and monitoring progress, thereby facilitating a safe and confident transition from hospital to home. This support reduces the likelihood of readmission due to nutrition-related complications and empowers patients and families in their own care.

Conclusion
The nutrition support team is a cornerstone of modern clinical care, addressing the critical issue of malnutrition in hospitalized patients. Through a collaborative, multidisciplinary approach, the team ensures the effective and safe delivery of nutritional therapy, whether through oral, enteral, or parenteral routes. By proactively screening for risk, implementing evidence-based care plans, and providing continuous monitoring and education, NSTs significantly improve clinical outcomes, reduce complications, shorten hospital stays, and contribute to overall cost savings. Their function is not merely to provide nutrition but to manage and optimize the complex process, from hospital admission through to outpatient care, ultimately enhancing patient safety and recovery.
