Learning Objectives

• Explain nutrition and its significance.

• Identify essential nutrients and their roles in physiological functions and health.

• Classify nutrition status based on criteria.

• Recognize the importance of nutritional screening in healthcare.

• Describe methods for assessing nutritional needs.

Importance of Nutrition in Healthcare

• Nutrition care is integral to quality patient care.

• Nutrition screening and assessment are essential components of the care process.

• No single clinical or lab parameter indicates nutrition status; multiple sources must be analyzed.

Understanding Nutrition

• Definition: The science studying food effects on the body; includes intake, digestion, absorption, and metabolism.

• Key Components:

  • Food: Any consumed substance providing nutritional support.

  • Nutrients: Chemical substances in food necessary for growth and health.

• Significance:

  • Essential for growth, weight maintenance, immune function, and mental health.

Nutrients Overview

• Macronutrients:

  • Carbohydrates: Provide energy, crucial for brain function and activity.

  • Proteins: Necessary for growth, tissue repair, hormones, and enzymes.

  • Fats: Provide energy storage, hormone production, and fat-soluble vitamin absorption.

• Micronutrients:

  • Vitamins: Support bodily functions (e.g., immune response, energy production).

  • Minerals: Vital for bone health, fluid balance, and muscle function.

• Water: Critical for hydration, nutrient transport, and temperature regulation.

Nutrition's Role in Health

• Physical Health:

  • Supports immune functions; reduces chronic disease risks (obesity, diabetes).

• Mental Health:

  • Influences brain health and mood; deficiencies can cause fatigue, depression.

• Preventive Health:

  • Good nutrition prevents malnutrition, reduces healthcare costs, and improves life quality.

Nutritional Assessment Components

• Medical and Dietary History:

  • Identify factors affecting nutritional status (e.g., chronic diseases, digestive issues).

• Nutrition-Focused Physical Exam (NFPE):

  • Assesses signs of malnutrition (muscle wasting, skin changes).

• Anthropometric Measurements:

  • Includes height, weight, and body mass index (BMI).

• Laboratory Assessments:

  • Evaluate nutrient levels and deficiencies.

Importance of Nutritional Screening

• Nutritional screening: Quickly identifies individuals at risk for malnutrition.

• Effective assessment: Monitors clinical outcomes and informs care plans.

• Routine Monitoring: Helps in timely interventions and patient outcomes.

Challenges and Complications of Nutrition Assessment

• Malnutrition Risks: Higher in those with limited food access.

• Both deficiencies and excess intake can lead to health issues.

Enteral Nutrition (EN) Overview

• Definition: Delivering nutrients directly into the GI tract using feeding tubes.

• Indications for Use: Gastrointestinal tract must be functional; suitable for patients unable to eat.

• Benefits: Maintains gut integrity and lowers infection risks compared to parenteral nutrition (PN).

Enteral Nutrition Administration Methods

• Types: Continuous, cyclic, bolus, intermittent.

• Route Selection: Depends on patient condition, feeding method tolerance, and GI tract function.

Parenteral Nutrition (PN) Overview

• Definition: Nutritional support delivered through IV; used when the GI tract is non-functional.

• Key Components:

  • Macronutrients: Proteins, dextrose, lipid emulsions.

  • Micronutrients: Affects fluid and electrolyte balance.

Pharmacist's Role in Nutrition Support

• Core Responsibilities:

  • Designing and verifying individualized PN therapy;

  • Monitoring patient responses to PN therapy;

  • Collaborating with interdisciplinary teams for comprehensive care.

Challenges Related to Nutrition Support

• Shortages of Components: Can affect therapy delivery.

• Managing Complications: Requires careful monitoring and protocol adherence.

Conclusion

• Maintaining optimal nutrition support requires thorough assessments, individualized care plans, and close monitoring. Effective nutrition intervention is essential for promoting recovery and improving patient outcomes.
