Abstract
Aim: This study investigated the effect of severe hyperglycemia episodes on survival and associated factors related to risk of mortality in type 2 diabetes mellitus (DM) patients with dementia. Methods: We enrolled all type 2 DM patients newly diagnosed as having dementia in Taiwan from 1998 to 2005. These patients were categorized into those who had hyperglycemia episodes and those who did not based on whether or not they had been hospitalized for hyperglycemia after dementia diagnosis. Factors independently associated with mortality were evaluated. Results: Of 5314 patients identified, 303 (5.7%) had at least one hyperglycemia hospitalization. Patients with at least one hyperglycemia hospitalization had a 30% greater risk of mortality than those who had no such admissions (adjusted hazard ratio: 1.30, 95% confidence interval: 1.09–1.55). Other variables, including age, sex, geographical region, insurance amount, patient with congestive heart failure, cerebrovascular disease, renal disease, use of anti-hypertensive drugs, use of anti-lipid drugs, and use of insulin were independently associated with risk of mortality. Conclusion: Severe hyperglycemia is common in type 2 DM patients with dementia and it substantially shortens their life. The findings of this study suggest a great need to improve care in DM patients with dementia. ? 2018 The Authors
