Comprehensive risk assessments of diabetic patients from seven Asian countries: The Joint Asia Diabetes Evaluation (JADE) program

Background: The aim of the web-based Joint Asia Diabetes Evaluation (JADE) program is to establish a registry for quality assurance, monitoring, and evaluation. Methods: The JADE electronic portal provides templates for data collection, supplemented by risk stratification, care protocols, and decision support. Herein, data from 3687 patients with Type 2 diabetes, enrolled over 15months in 2007-2009 from seven Asian countries, are reported. Results: Of the patients, 46.1% were men, the median (range) age was 58 (15-93years), and median disease duration was 6.5 (0-71) years; 16.2% had at least one cardiovascular-renal complication (10.0% coronary heart disease, 3.3% stroke, 3.1% peripheral vascular disease, 0.4% end-stage renal disease), 20.4% had diabetic retinopathy, 15.0% had sensory neuropathy, 7.5% had chronic kidney disease, and 20.7% of men had erectile dysfunction. Hypertension, dyslipidemia, and central obesity affected 84.6%, 76.8%, and 53.5% of patients, respectively. Treatment targets were HbA1c <7% in 35.3%, blood pressure <130/80mmHg in 32.3%, and low-density lipoprotein-cholesterol <2.6mmol/L in 34.0%. The rate of attaining one, two, and three targets was 38.7%, 23.4%, and 5.4%, respectively. Using the JADE Risk Engine, 60% of patients with clinical complications and 20% of those with multiple risk parameters were predicted to have a major event within 5years. Older age, short disease duration, adherence to diet, control of other risk factors, and not smoking were independently associated with HbA1c <7% (all P<0.05). Conclusions: It is possible to use a web-based protocol to establish a registry for risk stratification and facilitate early intervention.
