Objective: This study aimed to analyze the prevalence and nutritional status of patients with dysphagia using the NationalHealth Insurance Claim database collected from all Koreans. Methods: According to the claim data from the National Health Insurance Service from 2007 to 2017, we calculatedthe prevalence, comorbidity, and direct medical costs of dysphagia patients. We analyzed the difference in medicalcosts according to the malnutrition rate and presence of malnutrition. Results: The prevalence of dysphagia was 635.4 per 100,000 population in 2007 but increased to 1031.6 in 2017. Theproportions of type insurance showed an increasing trend in both health insurance and national free medical care,while nursing hospitals showed a significant increase of 8.46%. Esophageal and gastrointestinal disorders accountedfor the highest number of diseases with dysphagia. The average medical expense per person for dysphagia was11,984,632 Korea Won (KRW), and the average length of hospital stay was 154.1 days. The malnutrition rate of patientswith dysphagia was 686.8 out of 100,000 people in 2007 to 362.9 out of 100,000 people in 2017. The malnourishedgroup had 70.7 more inpatient hospital stays and nine more outpatient visits than the non-malnourishedgroup. Conclusion: The proportion of nursing hospitals and medical expenses increased significantly in the number of patientswith dysphagia, and the length of hospital stay and medical costs were higher with malnutrition. As incidenceof dysphagia patients may increase due to aging, active management of dysphagia is required to improve the patient’sprognosis and quality of life.
