Although there are numerous studies on diabetes mellitus in Saudi Arabia, data on the extent to which American Diabetic Association (ADA) standards of diabetic care are met, is scarce. We studied the computerized records of adult diabetic patients followed-up in outpatient internal medicine clinics at our tertiary care center in Riyadh, Saudi Arabia to find out how many of them met the ADA standards of diabetic care regarding fasting blood glucose, HbA1c, LDL-C, hypertension, proteinuria screening and use of anti-platelet, lipid lowering or recommended anti-hypertensive medications. Out of 1,188 type-2 diabetic patients studied, blood pressure readings were available in 1180 (99%) while results of fasting blood glucose, HbA1c, LDL-C and albuminuria screening were available for 1123 (95%), 968 (81%), 1037 (87%) and 307 patients, (26%) respectively. Patients achieving the ADA targets for overall, systolic and diastolic blood pressure, fasting blood glucose, HbA1c, LDL-C and albuminuria screening were 39.0%, 40.6%, 74.6%, 25.0%, 21.8%, 55.5% and 34.9%, respectively. For prevention of cardiovascular events, 61.0%, were using angiotensin converting enzyme inhibitors (ACE-I) or angiotensin-2 receptor blockers (ARBs) or both, while 71.5% and 72.3% of our patients were on anti-platelet and statin medications, respectively. In conclusion, as reported in most other studies, we also found that ADA standards of diabetic care are not met in most of our diabetic patients, indicating that these standards are easy to preach than to practice. There is need for further research to investigate the reasons for this failure and to adopt better multi-disciplinary approach and realistic targets in the future.
