Glucometer Usability Challenges Among Adults 65 and Older with Type 2 Diabetes

Key Highlights

  • Older adults with type 2 diabetes mellitus face both physical and cognitive challenges in using glucometers.
  • Features like connectivity and digital interfaces are often underused by patients but valued by clinicians.
  • Simpler glucometer designs are preferred by elderly patients, while providers favor advanced features for treatment customization.
  • Patient and provider feedback suggest a dual-design approach to improve usability and healthcare outcomes.

In a study presented at the American Diabetes Association’s 85th Scientific Sessions in Chicago, IL, researchers assessed the usability of glucometers in patients aged 65 years and older with type 2 diabetes mellitus (T2DM). The findings highlighted key usability barriers in this population, including age-related physical and cognitive limitations. While patients expressed general satisfaction with current glucometer functionalities, they struggled with device operation due to factors such as reduced dexterity and poor vision. Meanwhile, healthcare providers emphasized the utility of digital features for monitoring and treatment management, despite their limited adoption among older patients.

This investigation was prompted by the recognition that self-monitoring of blood glucose (SMBG) is vital to effective diabetes care, yet remains challenging for older adults. Age-related impairments can interfere with the use of glucometers, reducing adherence and potentially compromising glycemic control. Improving the design and usability of these devices could bridge this gap and enhance both patient experience and clinical outcomes.

The study was conducted between January 2022 and April 2024 at PSH, Vadodara. A total of 100 patients with T2DM and were aged 65 years or older participated in interviews evaluating their experience with different glucometer models. The research team also gathered insights through consultations with three physicians and senior residents. Usability, satisfaction, and barriers were examined, and focus group discussions provided supplemental qualitative data to inform potential improvements.

Results showed that while patients and clinicians generally approved of basic glucometer functions, significant challenges persisted. Older patients frequently encountered difficulties related to physical limitations—such as arthritis and impaired vision—and cognitive issues, such as forgetfulness or confusion with interface navigation. Although many devices now include advanced digital features like wireless connectivity and interactive displays, these were often viewed as unnecessary or overly complex by the older participants. In contrast, healthcare professionals appreciated these features for their ability to support remote monitoring and personalized treatment adjustments. This disconnect underscores the need for a user-centric approach that prioritizes intuitive design for geriatric patients while retaining technical capabilities that support clinician involvement.

“Future glucometer models should balance simplicity for users with enhanced connectivity for healthcare providers to improve care and adherence,” the authors concluded.
