|Official Title:||Progression From Impaired Fasting Glucose to Type 2 Diabetes Mellitus Among Subjects With and Without Hypertension in Primary Care Setting|
- Number of subjects develope Diabetes Mellitus [ Time Frame: 2005 to 2012 ]
We use the subject list drawn by the above criterion to retrieval the subsequent attendance record results annually (see Table 1 for the study method). Subjects are defined to have diagnosis of diabetes if they have physician coded of T90 or they have been prescribed of antidiabetic drugs (BNF(24) section 6.1 and 6.2). Each subjects of the cohort was followed to the date of IFG diagnosis and date of T2DM diagnosis. For IFG subjects who fulfilled the DM diagnosis criteria twice, only the earliest occurrence of T2DM diagnosis was recorded.
Other outcomes we are going to measure include age, sex, paying status in the consultation we first diagnosed to have IFG. We will see whether they have physician diagnosis of hypertension by coding International Classification of Primary Care (ICPC-2) coded as K86 uncomplicated hypertension or K87 complicated hypertension, or they have been prescribed with antihypertensive drugs (British National Formulary BNF(24) section 2.5).
