Evaluation of the Effectiveness of Insulin Injection Technique Education on Glycemic Control in Geriatric Patients with Type 2 Diabetes Mellitus- A prospective, randomized, controlled, parallel-group interventional study

Geriatric patients with T2DM face unique barriers to effective insulin self-administration due to age-associated factors such as cognitive decline, poor vision, tremors, and polypharmacy. These challenges often result in improper injection practices like site reuse, incorrect angles, and needle reuse, which contribute to complications such as lipohypertrophy, poor insulin absorption, and suboptimal glycemic control. Despite the availability of international guidelines, educational interventions remain underutilized in Indian clinical settings, especially in the older adults. This study aims to assess whether structured, tailored, and reinforced education can translate into better clinical and behavioral outcomes for this vulnerable population.
