Abstract
PurposeLittle information is available on the influence of diabetes mellitus on the short-term clinical outcomes of patients with bleeding peptic ulcers. The aim of this study is to investigate whether diabetes mellitus influences the short-term clinical outcomes of patients with bleeding peptic ulcers using a Japanese national administrative database.Materials and MethodsA total of 4863 patients treated by endoscopic hemostasis on admission for bleeding peptic ulcers were referred to 586 participating hospitals in Japan. We collected their data to compare the risk-adjusted length of stay (LOS) and in-hospital mortality of patients with and without diabetes mellitus within 30 days. Patients were divided into two groups: patients with diabetes mellitus (n=434) and patients without diabetes mellitus (n=4429).ResultsMean LOS in patients with diabetes mellitus was significantly longer than those without diabetes mellitus (15.8 days vs. 12.5 days, p<0.001). Also, higher in-hospital mortality within 30 days was observed in patients with diabetes mellitus compared with those without diabetes mellitus (2.7% vs. 1.1%, p=0.004). Multiple linear regression analysis revealed that diabetes mellitus was significantly associated with an increase in risk-adjusted LOS. The standardized coefficient was 0.036 days (p=0.01). Furthermore, the analysis revealed that diabetes mellitus significantly increased the risk of in-hospital mortality within 30 days (odds ratio=2.285, 95% CI=1.161-4.497, p=0.017).ConclusionThis study demonstrated that presence of diabetes mellitus significantly influences the short-term clinical outcomes of patients with bleeding peptic ulcers.
