PICO(T) Summary:
Population (P): Adults with type 2 diabetes mellitus treated with basal insulin.
Intervention (I): Continuous glucose monitoring (CGM).
Comparison (C): Standard diabetes education and self-monitoring of blood glucose (SMBG) without CGM.
Outcome (O): Change in HbA1c levels over time (glycemic control).
Time (T): Six-month study period.
Study Overview:
Martens et al. (2021) conducted a randomized clinical trial (MOBILE Study) to evaluate whether continuous glucose monitoring improves glycemic control in adults with type 2 diabetes treated with basal insulin. Participants were randomized to either CGM or standard diabetes education with routine self-monitoring.
Pathophysiological Findings:
-
Continuous glucose monitoring provided real-time feedback on glucose fluctuations, allowing more precise adjustments to insulin dosing and lifestyle interventions.
-
CGM helped detect hyperglycemia and hypoglycemia episodes that standard SMBG might miss, thereby reducing prolonged periods of hyperglycemia that contribute to chronic complications such as microvascular damage (retinopathy, nephropathy, neuropathy) and macrovascular complications (atherosclerosis).
-
Over six months, CGM users experienced significant reductions in HbA1c compared to the standard care group, demonstrating improved overall glycemic control.
Relevance to Nursing Practice:
-
Nurses play a critical role in patient education, including teaching patients how to interpret CGM data and adjust insulin and diet accordingly.
-
Understanding the pathophysiology behind fluctuating glucose levels enables nurses to explain the risks of uncontrolled hyperglycemia and hypoglycemia to patients.
-
Implementation of CGM can improve patient engagement, adherence to therapy, and self-management skills, ultimately improving clinical outcomes.
