Background: This study aimed to explore the long-term management of diabetes patients in domestic general hospitals by reviewing 2013 and 2018 data on diabetes management status.Methods: Of 1,802 type 2 diabetes patients who received outpatient treatment at nine general hospitals in Korea and who participated in the 2013 study, 1,124 were enrolled in this study. General characteristics, comorbidities, complications, and management were investigated through medical records.Results: The average age of the subjects was 65.4 ± 10.6 years, the average duration of diabetes mellitus was 15.6 ± 8.0 years, and 58.2% of the subjects had a family history of diabetes. Concomitant diseases were hypertension in 63.0% and dyslipidemia in 78.8%. Diabetic retinopathy was observed in 31.5%, nephropathy in 24.6%, and neuropathy in 24.5%. The mean glycosylated hemoglobin (HbA1c) level was 7.4 ± 2.2% and according to Korean Diabetes Association guidelines, 20.4% of patients with diabetes achieved a HbA1c level of < 6.5%, 70.1% achieved a blood pressure of < 140/85 mm Hg, and 77.1% achieved a low density lipoprotein cholesterol level of < 100 mg/dL. The target achievement rate was 12.5% for blood sugar, blood pressure, and lipid parameters.Conclusion: In diabetes management, blood sugar control was poor compared to blood pressure and lipid control. A systematic management plan is needed to ensure proper blood sugar control.

Objective To develop and examine the psychometric properties of the Korean Health Literacy Scale for Diabetes Mellitus (KHLS-DM), and to establish reasonable cutoff scores. Methods Initially, 299 items were generated to measure diabetes-related words, numeracy, and information utilization. Content validity assessment and preliminary tests were conducted. After exploratory factor analysis (EFA) and Rasch analysis, the remaining 65 items were administered to a quota sample of 500 diabetic patients aged 40–74 years. The items were narrowed down to 58 items based on an item fit index. To obtain cutoff scores, Jaeger’s method and the Bookmark method were employed. Results A confirmatory factor analysis (CFA) was performed, and a three-factor model was supported (χ2/df = 3.891, CFI = 0.92, TLI = 0.91, RMSEA = 0.04). The overall scores ranged from 0 to 58, and two cutoff points were established. The scale exhibited good internal consistency (Cronbach’s α = 0.83). Conclusions The KHLS-DM is a reliable and valid measure with cutoff points to classify individuals into three groups (adequate, marginal, and inadequate). Practice implications The standard setting may be useful for researchers to validate health literacy measures in other countries and populations.

Background: This study aimed to investigate the goal attainment rates for hemoglobin A1c (HbA1c), blood pressure (BP), and low-density lipoprotein cholesterol (LDL-C) in elderly patients with type 2 diabetes. Methods: The subjects were 762 over 65 years old patients with type 2 diabetes taking a hypoglycemic agent. Data were collected by reviewing medical records and included general characteristics, biochemical tests, prescribed pharmacologic agents, and complications. Results: The goal attainment rates (mean value) for HbA1c, BP, and LDL-C were 50.4% (7.3% ± 1.2%), 78.9% (126.0 ± 15.1/72.1 ± 10.0 mm Hg), and 60.6% (88.6 ± 29.9 mg/dL). Diabetes-related complications for retinopathy, nephropathy, neuropathy, and cardio-cerebral vascular disease were 36.3%, 37.2%, 23.6%, and 31.9%, respectively. Life habit-related variables positively associated with goal attainment were not drinking alcohol and exercise for HbA1c, not smoking for BP and not drinking alcohol for LDL-C. Metabolic adjustment indicator-related significant variables for complications were HbA1c in retinopathy, BP in nephropathy, and LDL-C in cardio-cerebral disease. Conclusion: We found that goal attainment rates for parameters of metabolic adjustment were not high in elderly patients with type 2 diabetes. Thus, diabetes educators should be concerned about metabolic adjustment indicators. Also, case management guidelines according to elderly patient health and functional status should be developed to help manage metabolic adjustment.

Background In Korea, the prevalence, complications, and mortality rate of diabetes are rapidly increasing. However, investigations on the actual condition of diabetes management are very limited due to lack of nation-wide research or multicenter study. Hence, we have minutely inquired the current status of diabetes management and achievement of glucose target goal in general hospital offering education program. That way, we are able to furnish data for policy making of diabetes education and draw up guideline which may allow us to reduce the morbidity and mortality of diabetes. Methods The subjects consisted of 2,610 patients with type 2 diabetes who visited the 13 general hospital in Seoul or Gyeonggi region from March 19 to May 29, 2013. General characteristics, associated diseases, complications, and management status were investigated. Results The mean age was 61.0±11.6 years, body mass index was 25.0±3.3 kg/m2, and family history of diabetes was 50.5%. The mean duration of diabetes was 10.7±7.9 years and 53% received education about diabetes. The prevalence of hypertension and dyslipidemia were 59.2% and 65.5%, respectively, and 18.3% of the subjects were accompanied by liver disease. Diabetic retinopathy appeared in 31.6%, nephropathy in 28.1%, and neuropathy in 19.9% of the subjects. The mean glycosylated hemoglobin (HbA1c) level was 7.3%±1.3% and the achieving rate based on Korean Diabetes Association guideline (HbA1c
