Analysis of direct medical care costs of peptic ulcer disease in a Korean tertiary medical center.

ABSTRACT

OBJECTIVES: There have been no reported data on the medical care cost of idiopathic peptic ulcer disease (PUD) compared with H. pylori (+) and/or NSAID (+) cases although H. pylori-negative idiopathic ulcers are increasing. The aim of this study was to investigate the direct medical care costs of PUD based on whether it was H. pylori infection/from NSAIDs or idiopathic. MATERIAL AND METHODS: One hundred and seventy three patients with PUD comprising H. pylori and/or NSAID use-associated PUD (n = 145) and idiopathic PUD (n = 28) were prospectively enrolled in this study. The direct medical care costs were analyzed retrospectively for the patients with PUD during a one-year follow-up period. RESULTS: The recurrence rate within one year was significantly higher in idiopathic PUD than H. pylori and/or NSAID-associated PUD (p = 0.002). Direct medical care costs of idiopathic PUD ($2483.8) were higher than in patients with H. pylori and/or NSAID-associated PUD ($1751.8) resulting from longer duration of medication and higher proportion of endoscopic hemostasis and hospitalization. CONCLUSIONS: More clinical research is needed to improve outcome and reduce recurrence rate and medical care costs of idiopathic PUD.
