1165-P: Combined Severe Diabetic Complications: The New Life-Altering Outcome

Since advanced microangiopathy of diabetes severely impairs activities of daily living (ADL) and quality of life (QoL) and macroangiopathy is life-threatening regardless of severity, treatment of diabetes requires appropriate risk management to avoid all such complications. However, current studies have analyzed and reported diabetes complications separately, despite varying incident rates and impacts on ADL/QoL and severity of illness. It is difficult to determine which predictors should be prioritized when extrapolating the results of these studies to the comprehensive care of individual patients. We defined the combined severe diabetic complications as a new life-altering outcome and determined the association of established risk factors with combined severe diabetic complications. We analyzed data from a nationwide database involving 36,994 participants with diabetes mellitus without any prior life-altering complication of diabetes during 2008-19. Combined severe diabetic complications included severe diabetic eye disease, initiating dialysis, coronary artery disease (CAD) , cerebrovascular disease (CVD) , heart failure (HF) , or amputation which were determined according to ICD-codes, medication and medical procedures. During a median follow-up period of 5.0 years, the following events occurred: severe diabetic eye disease, 774; dialysis initiated, 134: CAD, 703; CVD, 535; HF, 161; and amputations, 31. Multivariate Cox regression model showed the HRs per 1SD for combined severe diabetic complications of HbA1c, SBP, current smoking, HDL-C, BMI and LDL- C were 1.54 (1.49-1.59) , 1.37 (1.31-1.42) , 1.35 (1.23-1.48) , 0.83 (0.79-0.88) , 0.85 (0.81-0.90) and 1. (1.06-1.16) , respectively. We found that HbA1c was the most strongly associated with combined severe diabetic complications among established risk factors. Also, our results implied the necessity of revisiting the value of BMI in risk management for combined severe diabetic complications.
