Transition to Hospital Discharge in Insulinized Patients With Type 2 Diabetes Mellitus

The transition from hospital to home is a clinically vulnerable phase for patients with type 2 diabetes mellitus (T2DM), particularly for those who are newly initiated on insulin therapy during hospitalization. This period is characterized by increased therapeutic complexity, limited patient confidence with insulin use, and heightened risk of poor glycemic outcomes. Suboptimal adherence to insulin regimens-including missed or delayed doses-is common and has been associated with adverse clinical events, reduced quality of life, and higher healthcare utilization, including unplanned readmissions. While continuous glucose monitoring (CGM) systems and smart insulin pen caps have individually shown promise in improving glycemic control and treatment adherence, there is a lack of robust data regarding their effectiveness when introduced in the peri-discharge period. Importantly, the transition from inpatient to outpatient care has been highlighted as a critical moment to implement structured, technology-supported interventions aimed at improving self-management and continuity of care. This study investigates whether the combination of CGM and Insulclock® technology, initiated during hospitalization and continued after discharge, improves glycemic control and adherence in insulin-treated T2DM patients. Unlike prior studies, this trial evaluates these devices not only as monitoring tools but also as real-time decision-making supports during a period of high clinical risk. In addition to assessing standard glycemic metrics - including time in range (TIR), time below and above range (TBR, TAR), coefficient of variation, and HbA1c - the study will measure patient-reported treatment satisfaction and unplanned hospital readmissions within 30 days. The outcomes of this research may inform future protocols for diabetes discharge planning and support the integration of connected technologies into standard care pathways for insulin initiation in hospitalized patients.
