Diabetes is a global health concern that requires urgent attention due to its increasing incidence and potential for serious health problems if not managed properly. In India, the number of individuals with diabetes is alarmingly high and expected to rise significantly in the coming years.2 The World Health Organization reports that a large proportion of Indians are unaware of their diabetes status, indicating a need for improved detection and management strategies.3

Maintaining optimal blood glucose control is crucial for managing type 2 diabetes mellitus (T2DM) and preventing complications. However, achieving glycemic control can be challenging due to various factors that affect blood glucose levels throughout the day. Therefore, regular monitoring is recommended, especially for individuals under the age of 45 and those with risk factors for T2DM and prediabetes. Lifestyle interventions and self-management education are also endorsed as effective strategies to prevent or delay the onset of T2DM.4,5

Digital health technologies have emerged as valuable tools for self-management of chronic diseases, including diabetes. These technologies gather data that can contribute to improving the quality of healthcare and addressing the increasing burden of diabetes. The Indian government has recognized the potential of digitization in healthcare and has launched initiatives, such as the National Digital Health Mission, to integrate technology into healthcare delivery. 7

Two digital monitoring methods, self-monitoring blood glucose (SMBG) and continuous glucose monitoring (CGM), have shown promise in helping individuals with T2DM achieve adequate glycemic control. SMBG, although a traditional method, has been proven effective for patients on insulin therapy. However, its impact on T2DM patients not on insulin therapy remains uncertain. CGM, on the other hand, offers real-time blood glucose monitoring and provides valuable insights into treatment and lifestyle impacts on daily glucose levels. It also helps monitor glycemic variability and motivates patients to manage their diabetes effectively.

Despite the potential benefits of digital technology in providing timely and connected care through real-time transmission, there is a dearth of Indian studies evaluating the role of digital technology in the effective management of T2DM. However, some studies1,20 have demonstrated the effectiveness of smartphone-connected glucometers and digital therapeutic interventions in improving glycemic control and reducing hypoglycemia episodes in Indian T2DM patients. To address this research gap and further enhance blood glucose monitoring and control, this study aims to evaluate the effectiveness and safety of a comprehensive diabetes care program (CDCP) in individuals with T2DM.
