Core Responsibilities

Primary Functions

  • Conduct comprehensive nutrition assessments using patient history, anthropometrics, laboratory data, medication review, and validated screening tools to establish baseline nutritional status and diagnose nutrition-related problems.
  • Develop and implement individualized medical nutrition therapy (MNT) plans tailored to patient diagnoses (e.g., diabetes, renal disease, heart failure, oncology, GI disorders, critical care) that specify caloric, macronutrient and micronutrient goals, timing, and monitoring parameters.
  • Provide one-on-one and group nutrition counseling using evidence-based behavior change techniques, motivational interviewing, and culturally competent education materials to improve adherence and clinical outcomes.
  • Manage complex nutrition support cases including enteral and parenteral nutrition: calculate macronutrient needs, select appropriate formulas, write orders, monitor tolerance and metabolic complications, and coordinate with pharmacy and nursing for safe administration.
  • Perform nutrition-focused physical exams (NFPE) to detect signs of malnutrition, muscle wasting, and micronutrient deficiencies, and translate findings into actionable care plans.
  • Document nutritional assessments, care plans, progress notes, and outcomes accurately and timely in the electronic medical record (EMR) ensuring compliance with organizational, state, and CMS documentation standards.
  • Collaborate daily with physicians, nurses, pharmacists, therapists, case managers, and social workers to integrate nutrition goals into the overall plan of care and support discharge planning and transitions of care.
  • Implement and monitor tube-feeding protocols, adjust feeding rates and concentrations based on tolerance and lab results, and troubleshoot GI intolerance, aspiration risk, and metabolic complications.
  • Provide diabetes self-management education and support (DSME) including carbohydrate counting, insulin adjustment strategies, and coordination with certified diabetes educators when appropriate.
  • Perform nutrition screening within facility timelines, prioritize high-risk patients for RD assessment, and escalate concerns to the care team for early intervention to prevent adverse outcomes.
  • Calculate energy, protein, fluid, electrolyte and micronutrient requirements using evidence-based formulas and adjust recommendations for age, activity level, clinical condition, and comorbidities.
  • Lead or participate in multidisciplinary rounds and nutrition care conferences to advocate for nutrition interventions and ensure continuity and quality of care.
  • Supervise, train, and precept dietetic interns, new hires, and support staff; provide constructive feedback and ensure competency in clinical procedures and documentation.
  • Monitor and report nutrition-related outcomes and key performance indicators (KPIs) such as reduction in malnutrition risk, readmission rates, patient satisfaction, and nutrition consult turnaround times.
  • Ensure compliance with federal, state, and accreditation standards (e.g., CMS, JCAHO) related to nutrition care, food safety, infection control, and dietary accommodations.
  • Oversee therapeutic menu modifications and tray accuracy in collaboration with foodservice teams to meet medical prescriptions, texture modifications, and cultural/religious dietary needs.
  • Conduct medication–nutrition interactions review and communicate potential impacts of medications (e.g., prednisone, metformin) on nutritional status and metabolism to the prescriber team.
  • Educate nursing and ancillary staff on nutrition protocols, tube-feeding administration, aspiration precautions, and safe oral intake progression to improve interdisciplinary competence.
  • Participate in quality improvement projects and clinical research initiatives focused on nutrition protocols, malnutrition screening, glycemic control, or outcomes measurement; implement evidence-based improvements.
  • Provide community outreach, preventative nutrition programs, and population health initiatives to promote healthy eating, chronic disease prevention, and wellness across targeted populations.
  • Coordinate specialty nutrition services such as gestational diabetes counseling, pediatric growth and feeding interventions, geriatric malnutrition prevention, and oncology nutrition support, adapting approaches to patient lifecycle needs.
  • Manage nutrition-related billing and coding procedures (e.g., CPT codes for MNT) in coordination with financial services to ensure appropriate reimbursement and documentation for billed services.
  • Maintain current professional certifications, complete continuing education units (CEUs), and stay updated on emerging nutrition science, guidelines, and best practices to ensure high-quality patient care.
  • Lead nutrition policy development and protocol reviews for the facility, including standardizing nutrition screening tools, admission nutrition workflows, and emergency nutrition plans.
  • Address patient and family education needs, deliver discharge nutrition instructions, and arrange outpatient follow-up or referrals to community resources (e.g., WIC, meal programs) to support long-term nutrition goals.
  • Conduct nutrition risk stratification and care pathway development for high-risk cohorts (e.g., bariatric patients, transplant candidates, chronic kidney disease) to streamline interventions and reduce complications.
  • Respond to nutrition-related emergencies and assist in critical situations (e.g., refeeding syndrome, severe electrolyte imbalances) by providing rapid assessment, orders, and monitoring plans in collaboration with the critical care team.

Secondary Functions

  • Participate in hospital- or clinic-level committees such as nutrition steering, wound care, ethics, or patient safety committees to provide nutrition expertise.
  • Support program development for outpatient clinics, group classes, and telehealth nutrition services to expand access and continuity of care.
  • Contribute to patient education material development, social media outreach, and internal training modules to improve health literacy and brand visibility.
  • Assist with inventory control and vendor negotiations for clinical nutrition products and specialized formulas to maintain cost-effective supplies.
  • Provide coverage for foodservice operations during peak periods, including menu audits and patient satisfaction follow-up.
  • Coordinate specialty referrals to allied health providers (e.g., speech-language pathology for dysphagia, behavioral health for eating disorders) to create integrated care plans.
  • Participate in data collection and reporting for regulatory reviews, quality dashboards, and value-based care initiatives tied to nutrition outcomes.
