Objective Evaluation Tool for Texture-Modified Food (OET-TMF): Development of the Tool and Validation

Area of Science:

• Nutritional Science
• Food Science
• Gerontology

Background:

• Texture-modified diets (TMDs) are crucial for patients with swallowing difficulties, requiring nutritional adequacy, safe textures, and regulatory compliance.
• The food industry provides texture-modified foods (TMFs) for inpatients, but objective tools for selecting optimal options are needed.
• Improving food satisfaction for inpatients on TMDs is vital for their overall quality of life.

Purpose of the Study:

• To design and validate an objective tool for selecting foodstuffs for TMDs.
• To ensure TMDs meet nutritional requirements and swallowing safety for inpatients.
• To enhance patient satisfaction and quality of life through improved food selection.

Main Methods:

• Development of the "Objective Evaluation Tool for Texture-Modified Food" (OET-TMF) with seven items.
• Evaluation of nutritional quality, allergens, texture, viscosity, preparation, storage, shelf-life, and patient acceptance.
• Validation of the OET-TMF using four commercial TMFs and analysis of consumption and refusal rates.

Main Results:

• The OET-TMF categorizes TMF quality into high, good, medium, and low.
• All validated commercial TMFs scored between high and good quality.
• Higher OET-TMF scores showed a trend towards increased consumption and better patient acceptance, with lower scores correlating to higher refusal rates.

Conclusions:

• The OET-TMF effectively discriminates the quality of texture-modified foods.
• The tool demonstrates a relationship between assessed quality and actual patient intake and acceptance.
• Objective evaluation of TMFs using the OET-TMF can improve inpatient nutrition and food satisfaction.
