    Journal: J Diabetes Sci Technol; 2016 Sep; 10(5):1136-41. PubMed ID: 27390222.
    Abstract:
    BACKGROUND: Proper management of diabetes mellitus requires regular self-monitoring of blood glucose (SMBG). This research evaluated the usability of the Accu-Chek® Guide Meter that includes a spill-resistant vial, easier strip handling, and wireless connectivity to a mobile app. METHODS: A total of 197 participants were allowed to experience typical blood glucose testing tasks on the Accu-Chek Guide Meter, review data such as last result, patterns, and target percentage on the meter and on the mobile app, and then evaluate their experience through a human factors usability survey. Participants used a 6-point agree/disagree scale to rate 34 market statement questions. RESULTS: The results of a Pearson chi-square proportions test for each of the 34 market statement questions showed a significant difference (P < .0001) between the disagree responses (1-3) and agree responses (4-6). An overwhelming majority of participants found all aspects of the system, including the test strips, strip vial, and data analysis on the meter and the mobile app, to be a good fit for their lifestyle and to provide a better testing experience. CONCLUSIONS: This study found superior usability of the new meter system over the participants' current meters in both the United States and France.
