Antidiabetic drug regimens and glycemic control in type 2 diabetic patientsat Ramathibodi Hospital
Abstract:
Despite evidence that good glycemic control can improve medical outcomes,
management of type 2 diabetes mellitus (DM) is often unsuccessful. This retrospective
study was conducted at Ramathibodi hospital between July and November 2004. The
antidiabetic drug regimens and glycemic control among 246 type 2 DM patients were
collected from medical records started from their first diagnosis until their last visits in
September 2003. Drugs used in controlling the comorbidities, hypertension and
dyslipidemia are investigated as well. The majority of patients were female (64.78%).
The average age was 62±11.21 years, and the mean diabetes duration was 9±6 years.
A high portion of patients had also a diagnosis of hypertension, dyslipidemia or both
(76.83%, 75.20%, 59.35%, respectively).
Most patients (43.50%) were receiving dual oral antidiabetic drugs (OADs)
therapy. Pharmacologic management of hyperglycemia was intensified with duration
of diabetes. According to the Endocrine Society of Thailand, >70% of the patients are
considered as having poor glycemic controll. For the comorbidities, only 43.91% of
patients achieved the target blood pressure and 28.11% of patients achieved the target
lipidemia.
Only 106 patients completed information from their first DM diagnosis,
19.81% started with nondrug therapy. However, all patients finally started drug
therapy. After 3 months of treatment with the first regimen, only 33.02% of patients
can be considered as having good glycemic control, 66.98% of patients can be
considered as having effective treatment.
HbA1c is the primary target for glycemic control. However, the test is
expensive and only 158 from 246 patients (64.23%) have HbA1c data. Moreover, the
correlation between HbA1c and FPG when both values coexist is not as good as
expected (r=0.59).
