Evaluation of a Diabetes Data Management System

• Number of Participants That Rated 80% of Tasks as Very Simple, Simple, or Neither Simple Nor Difficult (Ease of Use of the Software Program) [ Time Frame: 1-2 hours ] [ Designated as safety issue: No ]

  After completing each task, subjects rated the ease of performing each task on a scale of 1 to 5.

  1. Very Simple
  2. Simple
  3. Neither simple nor difficult
  4. Difficult
  5. Very Difficult Outcome measure was the number of participants that rated 80% of tasks as 1,2, or 3.
• Number of Participants Rated as <= 3 (Success in Using the Program) [ Time Frame: 1-2 hours ] [ Designated as safety issue: No ]

  Subjects were rated by study staff as to their success at performing basic tasks. The rating scale was:

  1. successful
  2. successful after being referred to user instructions
  3. success with assistance (similar to a customer call)
  4. unsuccessful 5 = software problem Outcome measure was the number of participants rated as <= 3.
• Number of Participants That Could Answer at Least 85% of the Comprehension Questions Correctly (Comprehension of the Program Reports) [ Time Frame: 1-2 hours ] [ Designated as safety issue: No ]
  Subjects were asked thirty questions throughout the evaluation to test whether they understood the data displays, graphs and features of the software. Outcome measure was the number of participants that could answer at least 85% of the comprehension questions correctly.

• Ease of use of the software program [ Time Frame: 1 visit ] [ Designated as safety issue: No ]
• Success in using the program [ Time Frame: 1 visit ] [ Designated as safety issue: No ]
• Comprehension of the program reports [ Time Frame: 1 visit ] [ Designated as safety issue: No ]

The purpose of this study is to evaluate a diabetes data management program in the hands of potential users, both health care professionals and lay users.

Diabetes data management programs analyze blood glucose results downloaded from glucose meters to assist health care professionals or lay users manage their diabetes. During the study, subjects download meters, generate and print reports, evaluate the program's ease of use, and verify that they understand the program output.

Lay users males or females and health care professionals.

Inclusion Criteria:

• Health Care Professionals:

  1. Must have experience using diabetes data management software in the medical office such as downloading meters, reviewing reports (computer screen or printouts), or assisting in patients' diabetes disease management using software.
  2. May include: endocrinologists, primary care physicians, nurse educators, or other medical staff involved in downloading meters or interpreting the data output.

• Lay users must:

  1. Be at least 18 years of age.
