Abstract
Self-measurement and documentation of blood-glucose are critical elements of diabetes management, particularly in regimes including insulin. In this study, we analyze the usability of iBG-STAR, the first blood glucose meter connectable to a smartphone. This technology records glucometer measurements, removing the burden of documentation from diabetic patients. This study assesses the potential for implementation of iBG-STAR in routine care. Twelve long-term diabetic patients (4 males; median age of 66.5 years) were enrolled in the study. N = 4/12 reported diabetic polyneuropathy. Reported subjective mental workload for all tasks related to iBG-STAR was on average lower than 12 points, corresponding to the verbal code ‘nearly no effort needed’. A “Post Study System Usability Questionnaire”, evaluated the glucometer at an average value of 2.06 (SD = 1.02) on a 7-Likert-scale (1 = ‘I fully agree’ to 7 = ‘I completely disagree’) for usability. These results represent a positive user-experience. Patients with polyneuropathy may experience physical difficulties in completing the tasks, thereby affecting usability. Technologically savvy patients (n = 6) with a positive outlook on diabetes assessed the product as a suitable tool for themselves and would recommend to other diabetic patients. The main barrier to regular use was treating physicians’ inability to retrieve digitally recorded data. This barrier was due to a shortcoming in interoperability of mobile devices and medical information systems.
Highlights
With more than 415 million diabetic patients globally, the demand for diabetes management is on the rise [1]
Of the 12 participating patients 4 were male. n = 11/12 patients were suffering from diabetes for more than 10 years. n = 4/12 patients reported diabetic polyneuropathy. n = 11/12 were on insulin-therapy
All participants were familiar with daily glucose self-measurements. n = 8/12 documented with pen and paper, 4 stored data electronically on the blood glucose meter
Summary
With more than 415 million diabetic patients globally, the demand for diabetes management is on the rise [1]. A cornerstone of therapeutic management of diabetes is blood glucose selfmeasurement [2,3,4]. This data is a crucial prerequisite for therapeutic decision making [5].
