Arm Intervention/treatment
Experimental: Users of Onyx BG Meter / App System

Subjects with diabetes used the Onyx Blood Glucose (BG) Meter / App System at home. The enrollment goal for the intended use population:

  1. 40 to 70% of subjects will have type 1 diabetes
  2. Not more than 30% of subjects will use an insulin pump
 Device: Onyx BG Meter / App System
Subjects with diabetes used the Onyx BG Meter / App System at home and assessed software operations, ease of use of the system, and clarity and utility of user instructions.


Outcome Measures

Primary Outcome Measures :
  1. Percent of Responses From Persons Who Performed Each "Software Operations" Task and Rated Each Statement as Strongly Agree, Agree, or Neither Agree Nor Disagree. [ Time Frame: 3 weeks ]

    For "software operations" tasks, subjects rated statements about software operations tasks as 1Strongly Agree, 2Agree, 3Neither Agree nor Disagree, 4Disagree, 5Strongly Disagree, or 6No opinion. Software operations tasks included:

    • Obtain a synced blood glucose reading
    • Initiation and use of insulin bolus calculator
    • Access and interpret glucose displays such as expanded graph (modal day) and sequential views.


Secondary Outcome Measures :
  1. Percent of Responses From Persons With Diabetes That Rated Ease of Use For Onyx Glucose Meter and App System as Either Very Simple or Simple or Neither Simple Nor Difficult [ Time Frame: 3 weeks ]
    Staff obtained responses from persons with diabetes using short questionnaires to provide feedback on the basic operation of the Onyx Glucose Meter and App System. Subjects could respond '1Very Simple' or '2Simple' or '3Neither Simple nor Difficult' or '4Difficult' or '5Very Difficult' or '6No Opinion'.

  2. Percent of Responses From Persons With Diabetes That Either 'Strongly Agree' or 'Agree' or Are 'Neither Agree Nor Disagree' With Questionnaire Statements Regarding Clarity and Utility of User Instructions For Onyx Glucose Meter and App System [ Time Frame: 3 weeks ]
    Staff obtained responses from persons with diabetes using short questionnaires to provide feedback on the clarity and utility of user instructions for the Onyx Glucose Meter and App System. Subjects could respond '1Strongly Agree' or '2Agree' or '3Neither Agree nor Disagree' or '4Disagree' or '5Strongly Disagree' or '6No Opinion'.


Other Outcome Measures:
  1. HbA1c% From Study Start to End of Study [ Time Frame: 3 weeks ]
    Laboratory reports were used to compare HbA1c results from subjects at visit 1 with HbA1c results at Visit 2 (end of study).

  2. Average Change in Subject Fructosamine From Study Start to End of Study [ Time Frame: 3 weeks ]
    Laboratory reports were used to compare Fructosamine results from subjects at visit 1 with Fructosamine results at Visit 2 (end of study).

  3. Average Change in Subject Body Weight From Study Start to End of Study [ Time Frame: 3 weeks ]
    Subject Body Weight results at visit 1 were compared with Body Weight results at Visit 2 (end of study).

  4. Average Change in Total Daily Insulin Dose From Study Start to End of Study [ Time Frame: 3 weeks ]
    Subjects' self-reported Total Daily Insulin Doses at visit 1 were compared with their self-reported Total Daily Insulin Doses at Visit 2 (end of study).
