Abstract
Diabetes Mellitus (DM) is a common metabolic disorder and has been a major contributor to the ‘non communicable diseases’ group. Earlier detection is important to achieve glycaemic-target and to avoid it’s wide-ranged complications. In recent years, the incidence of newly diagnosed DM has been on the rise, reflecting the spectrum of disease-unawareness within our society. This study aimed to analyse the patterns observed in the diagnosis of DM and to derive meaningful suggestions based on the laboratory tests utilized. Fasting Blood Sugar (FBS) and glycated-haemoglobin (HbA1c) were assessed to evaluate the diabetes-status of all patients who exhibited admission-hyperglycaemia. Our findings revealed that 17% of the study-population were Diabetic (with 1% being newly detected DM); among the newly detected DM patients, 69% met both diagnostic criteria (regarding fasting-blood-sugar and glycated-haemoglobin); and FBS appeared more sensitive while HbA1c appeared more specific in detecting Diabetes. This study recommends that every hospitalised patient with an initial high blood-sugar reading (e.g. RBS>7.8 mmol/L) should be evaluated for diabetes using FBS and/or HbAl1c tests.
