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

Abstract

The aim of the web-based Joint Asia Diabetes Evaluation (JADE) program is to establish a registry for quality assurance, monitoring, and evaluation. 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 15 months in 2007-2009 from seven Asian countries, are reported. Of the patients, 46.1% were men, the median (range) age was 58 (15-93 years), 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 <130/80 mmHg in 32.3%, and low-density lipoprotein-cholesterol <2.6 mmol/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 5 years. 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). It is possible to use a web-based protocol to establish a registry for risk stratification and facilitate early intervention.
