Objective: Poor glycemic management increases the risk of cardiac, microvascular, and other complications. Therefore, timely assessment and control of glycemic levels is paramount in diabetes. Recent advancements in automated management methods is the use of a continuous glucose monitoring system (CGMS). The objective was to study its clinical and economic impact in the glucose level monitoring and how it can be effectively used or reimbursed for wider population.
Methods: Comprehensive search was done using multiple databases to capture relevant and most recent evidence. All steps were conducted by two independent researchers and discrepancies resolved by a third reviewer. Quality appraisal was performed by relevant scale depending on study design.
Results: Twenty-six and 12 studies were included for clinical and economic outcomes, respectively. Clinical outcomes like HbA1c and glucose variation, time in range, accuracy, etc. were captured. Comparison of different CGMS types was also reported. Major economic outcomes were direct cost, healthcare resource utilization, and work absenteeism.
Conclusions: CGMS in patients with diabetes is associated with a valuable clinical implications in reducing hypoglycemic events, glucose and HbA1c level. Additionally, it has an impact on direct and indirect costs of management. Further, quantitative analysis would be required to produce concrete evidence.
