Nutrition risk classification: a reproducible and valid tool for nurses

Area of Science:

• Clinical Nutrition
• Healthcare Quality Improvement
• Nursing Practice

Background:

• Early identification of hospitalized patients at nutritional risk is crucial for timely intervention.
• Integrating nursing staff into the nutrition screening process facilitates earlier assessment by registered dietitians.
• A validated and reproducible nutrition screening tool for registered nurses (RNs) is needed to classify patient nutritional status upon admission.

Purpose of the Study:

• To develop and validate an objective, reproducible nutrition screening tool for RNs.
• To enable accurate nutrition classifications for hospitalized patients.
• To facilitate earlier nutritional risk assessment by registered dietitians.

Main Methods:

• Modified the nursing admission assessment form to include key nutritional indicators.
• Conducted a two-phase study: Phase 1 assessed reproducibility between RNs and a nutritionist; Phase 2 validated the tool against prealbumin levels.
• Patients were classified as "at nutritional risk" or "low nutritional risk" based on screening responses.

Main Results:

• High interobserver agreement (97.3%) between RNs and nutritionists for nutrition classification.
• The screening tool demonstrated significant accuracy in identifying patients at nutritional risk (chi 2 = 8.9, p < .003).
• The tool achieved a sensitivity of 84.6% in identifying patients with low prealbumin levels.

Conclusions:

• This study presents the first nutrition screening tool specifically designed for RNs that has been rigorously tested for validity and reproducibility.
• The developed tool is effective in identifying hospitalized patients requiring nutritional assessment.
• Implementing this tool can enhance the efficiency and effectiveness of nutrition support in hospital settings.
