A New 5-Step Grading System of Oral Nutritional Support for Patients with Dysphagia / 日本農村医学会雑誌

ABSTRACT

  Patients with dysphagia suffer from various degrees of difficulty in eating or swallowing. To improve their oral intake, meals must be provided with due consideration given to individual patient's eating ability. In this study, we examined a newly developed grading system of oral nutrition, which comprised 5 grades (I-V) based on the degree of difficulty in swallowing each formula. Grades I-III are meals suitable for swallowing training, grade IV represents meals that were enough to meet nutritional requirements, and grade V meals for the preparatory stage leading up to the changeover from liquid to solid foods.<br>  To assess the 5-step grading system of oral nutrition, we worked out average ingestion rates in 23 patients with dysphagia. The ingestion rate was 75±21% for patients on grade IV oral nutrition, and 74±19% for those on grade V, with a combined rate of 74±20%. This was higher than the average ingestion rate in a previous study conducted before our introduction of the grading system for oral nutrition (Journal of the Japanese Association of Rural Medicine 57 83-88, 2008). We considered the surveillance data showed tendency to support the 5-step grading system, and in a case with dysphagia, this system actually brought about a remarkable improvement in ingestion. It has been introduced in our hospital since July 2008.
