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 AuthorsDementia; Diabetes mellitus; Hyperglycemia; Morbidity; Mortality[SDGs]SDG3antihypertensive agent; antilipemic agent; insulin; aged; Article; cerebrovascular disease; cohort analysis; congestive heart failure; controlled study; drug use; female; health insurance; hospitalization; human; hyperglycemia; kidney disease; major clinical study; male; mortality; mortality risk; multiinfarct dementia; non insulin dependent diabetes mellitus; observational study; priority journal; retrospective study; survival; Taiwan; very elderly; blood; complication; diabetic angiopathy; epidemiology; follow up; hyperglycemia; middle aged; multiinfarct dementia; non insulin dependent diabetes mellitus; time factor; Aged; Aged, 80 and over; Cohort Studies; Dementia, Vascular; Diabetes Mellitus, Type 2; Diabetic Angiopathies; Female; Follow-Up Studies; Humans; Hyperglycemia; Male; Middle Aged; Retrospective Studies; Taiwan; Time Factorsjournal article10.1016/j.jdiacomp.2018.10.014WOS:000458710600003
