Diabetes mellitus is a chronic disorder with many vascular complications, leading to significant morbidity and mortality. The prevalence of Type 2 diabetes mellitus in Malaysia has risen dramatically from 6.3% (NHMS 1 in 1986); to 8.3% (NHMS 2 in 1996); and to 14.9% (NHMS 3 in 2006). An audit was conducted on patient's medical records from selected MOH health facilities to assess the control of diabetes using HbA1c. The response rate was 69.6% and the control of diabetes was poor. Only 18.4% of patients with valid HbA1c had value less than 6.5%. This is notably worst amongst patients from younger age groups. Many recommended investigations such as fundoscopy and urine microalbumin had not been done regularly. Efforts to look for various vascular complications were under-reported. About 45% of patients had been treated with 2 oral antidiabetic agents; mainly the sulphonylureas and the biguanides. Only 13.3% of patients were on insulin despite having poorly controlled disease. There is an urgent need to improve the management of diabetes mellitus in these areas:- (i) improving the glycemic control status (particularly among younger diabetic patients) with early and optimal use of oral diabetic drugs and insulin; (ii) stringent monitoring of glycemic control with adequate funds for regular performance of HbA1c (at least every 6 monthly for all diabetic patients) (iii) organizing regular updates or interactive programme for diabetes healthcare providers from primary, secondary and tertiary care; (iv) ensuring regular and prompt review of diabetic complications so that the complications can be dealt with early; (v) producing more diabetes educators to strengthen and standardize the diabetes education programme; and promote patients adherence to non-pharmacological and pharmacological interventions.
