Context. Improving glycemic control requires interpretation and action on
blood glucose results. We evaluated the experience of patients using a blood
glucose meter (BGM) featuring a colour range indicator (CRI) in terms of
improving insight and glycemic control.
Materials and methods. 249 adults with type 2 diabetes (T2D) experienced
OneTouch Verio Flex™ (OTVF). Clinicians had routine clinical
conversations with all subjects at baseline in terms of introducing this new
BGM. No change in medication or insulin dosing were recommended.
Results. After three months, T2D subjects experiencing OTVF with a CRI
(n=111) reduced A1c by 1.24% compared to study baseline (p<0.05).
Subjects achieving pre-specified clinical goals with respect to lowering A1c
below 7.0% or 7.5% increased after three months home use of OTVF from
4.5% to 31.5% (n=35) and 9.9% to 43.2% (n=48), respectively. 92% (n=242)
reported that OTVF made them consider taking action when they had low or
high numbers and 91% (n=238) agreed it could help them stay healthier in
future between doctor visits because they knew what the numbers meant.
100% (n=17) of clinicians agreed OTVF helped their patients more easily
identify hypo or hyperglycemic episodes and that displaying results with a
CRI made their patients more inclined to act.
Conclusions. This observational study demonstrated that patients with type
2 diabetes using the OneTouch Verio Flex meter featuring a colour range
indicator significantly improved A1c levels. New insights and actions by
subjects may have translated into behavioural changes that resulted in
improvements in glycemic control.
