Diabetes Screening Algorithm

Screen every 3 years in patients > 40 years and no other risk factors (Table 5)

Earlier and more frequently in patients < 40 years with risk factors (Table 5) and as clinically indicated in patients > 40 with other risk factors

Do Fasting Plasma Glucose

Fasting Plasma Glucose

<5.7 mmol/ L

5.7 – 6.9 mmol/L Plus risk factor(s) for diabetes/IGT (Table 5)

6.1 – 6.9 mmol/L and no risk factors for diabetes/IGT (Table 5)

>/= 7.0 mmol/L

Rescreen as clinically indicated

2 hr. Plasma Glucose in a 75 gram Oral Glucose Tolerance Test

Classify Patient as:

	FPG	2hPG
Normal	<6.1	<7.8
IFG isolated	6.1-6.9	<7.8
IGT isolated	<6.1	7.8-11.0
IFG and IGT	6.1-6.9	7.8-11.0
Diabetes	>/+7.0 or >/=11.1

IFG Management

Strategies to prevent diabetes and modify CVD risk factors. Exercise and weight control are major considerations. Rescreen for diabetes at appropriate intervals.
