Graded nutritional interventions in patients with dysphagia after stroke: an assessment of the effectiveness of therapeutic strategies for different swallowing functions.

Objective: To evaluate the efficacy of graded nutrition intervention strategy in improving patients with different degrees of impaired swallowing function after stroke.

Methods: According to the way of nursing, the patients were divided into two group. The main outcome measure was Kota swallowing index (WSI) score, and the secondary outcome was complications during the intervention. SF-36 scale was used to evaluate the improvement of quality of life before and intervention.

Results: The WSI score in the control group was 62.34 ± 10.23 at 1 week after treatment, 70.52 ± 13.45 at 6 weeks after treatment, and 80.48 ± 9.87 at 12 weeks after treatment, while that in the intervention group was 71.45 ± 9.68 at 1 week after treatment, 75.81 ± 11.78 at 6 weeks after treatment, and 84.12 ± 14.32 at 12 weeks after treatment. The WSI scores of the intervention group were significantly higher than those of the control group (t = 5.634, p < 0.001), suggesting better swallowing function of the patients The incidence of pulmonary infection, malnutrition and gastroesophageal reflux in the intervention group was significantly lower than that in the control group (p < 0.05). There was no significant difference in throat inflammation and dehydration between the two groups (p > 0.05). In addition, graded nutrition interventions significantly improved patients' quality of life, including dimensions of physical functioning, role physics, physical pain, and social functioning.

Conclusion: Compared with conventional treatment, personalized graded nutrition intervention can significantly improve the swallowing function and reduce the pulmonary infection rate in patients with swallowing disorders after stroke.
