Physicians continue to recommend routine self-monitoring of blood glucose for patients with non-insulin treated type 2 diabetes, in spite of its lack of effectiveness, because they believe it drives the lifestyle change needed to improve glycemic control.
Researchers conducted a qualitative study of 17 primary care physicians exploring to what extent and why physicians still prescribe self-monitoring of blood glucose when the evidence shows that it increases costs without improving HbA1c, general well-being, or health-related quality of life.
In semi-structured interviews, proponents stated that self-monitoring works best at initial diagnosis, facilitating education and self-management, a view that may be encouraged by the American Diabetes Association's support of self-monitoring based on expert opinion. In contrast, opponents are concerned about lack of efficacy in lowering HbA1c, often citing peer-reviewed evidence to support their views, and believe office-based education encourages patient activation.
Health care systems have been shown to view self-monitoring of blood glucose as cost-saving and relatively harmless, yet previous research shows that it can be painful, inconvenient, and depressing for patients.
The authors suggest that targeting physician beliefs about the effectiveness of self-monitoring of blood glucose for patients with non-insulin treated type 2 diabetes, along with policy-based interventions, could reduce the practice.
