OBJECTIVE - Blued glucose awareness training (BGAT) has been shown to impro
ve awareness of blood glucose (BG! fluctuations among adults with type 1 di
abetes. This study investigates the long-term (12-month) benefits of BGAT-2
.
RESEARCH DESIGN AND METHODS - A total of 73 adults with type diabetes parti
cipated in a 6-month repeated baseline design with a 12-month follow up. At
6 months and 1 month before BGAT-2 and at 1, 6, and 12 months after BGAT-2
, subjects used a handheld computer for 50 trials and completed psychologic
al tests. Throughout assessment, subjects completed diaries, recording occu
rrences of diabetic ketoacidosis, severe hypoglycemia, and motor vehicle vi
olations. During follow-up, 50% of the subjects received booster training.
RESULTS - During the first and last halves of both the baseline period and
the follow-up period, dependent variables were generally stable. However, f
rom baseline to follow-up. BGAT-2 led to I) improved detection of hypoglyce
mia and hyperglycemia; 2) improved judgment regarding when to lower high DG
, raise low BG. and not drive while hypoglycemic; 3) reduction in occurrenc
e of diabetic ketoacidosis, severe hypoglycemia. and motor vehicle violatio
ns; and 4) improvement in terms of worry about hypoglycemia, quality of lif
e. and diabetes knowledge. Reduction in severe hypoglycemia was not associa
ted with a worsening of metabolic control (HbA(t)). The presence or absence
of booster training did not differentially affect these benefits.
CONCLUSION - BGAT has sustained broad-ranging benefits, independent of boos
ter Intervention.
