Clinical Usefulness of a Magnifier for Insulin Pen

Insulin treatment is crucial for glucose control. Many patients with type 2 diabetes exhibit inadequate glycemic control in spite of combination of oral antidiabetic drugs and eventually need insulin therapy. Patients who need insulin therapy are older and have poor visual acuity, which predispose to inaccurate dosing and consequent hyper or hypoglycemia.In this study, the investigators examined the clinical usefulness of a magnifier for elderly diabetic patients who had used insulin pens.

Primary outcomes

  1. the time spent to complete dialing up insulin pens

    Time frame: from to start dialing up the selected dose to to complete dialing up, assessed up to 10 minutes

    The investigators ask participants to dial up the random dose of insulin pens between 30 and 40 and measured the time spent to complete dialing up.

Secondary outcomes

  1. the dosing accuracy

    Time frame: from to start dialing up the selected dose to to complete dialing up, assessed up to 10 minutes

    The investigators ask participants to dial up the random dose of insulin pens between 30 and 40 and check whether they dial up the selected dose correctly.

  2. the convenience in using insulin pens

    Time frame: the duration of to complete filling up the questionnaires, an expected average of 10 minutes

    By structured questionnaires, the investigators ask participants about the convenience in dialing up to correct doses of insulin pens.

  3. the self-confidence in using insulin pens

    Time frame: the duration of to complete filling up the questionnaires, an expected average of 10 minutes

    By structured questionnaires, the investigators ask participants about the self-confidence in dialing up to correct doses of insulin pens

  4. the need for glasses in using insulin pens

    Time frame: the duration of to complete filling up the questionnaires, an expected average of 10 minutes

    By structured questionnaires, the investigators ask participants about the need for glasses in dialing up to correct doses of insulin pens

  5. the preferences for the use of a magnifier

    Time frame: the duration of to complete filling up the questionnaires, an expected average of 10 minutes

    By structured questionnaires, the investigators ask participants whether they prefer the use of a magnifier

  6. the recommendation for the use of a magnifier

    Time frame: the duration of to complete filling up the questionnaires, an expected average of 10 minutes

    By structured questionnaires, the investigators ask participants whether they recommend the use of a magnifier to others.
