Summary

Insulin injection pen devices (IIPD) are generally preferred over vial and syringe (VS) methods by both insulin users and non-users. Social acceptability strongly predicts IIPD preference, while ease of use and activity interference are key for VS preference discussions.

Area of Science:

  • Diabetes Management
  • Medical Device Technology
  • Patient Preferences

Background:

  • Patient preferences for insulin delivery devices, specifically vial and syringe (VS) versus insulin injection pen devices (IIPD), are not well-established between current insulin users and non-users.
  • Considering patient preferences may enhance treatment outcomes for individuals initiating or switching insulin therapy.

Purpose of the Study:

  • To investigate and compare the preferences for vial and syringe (VS) versus insulin injection pen devices (IIPD) among current insulin users and non-users.
  • To identify key attributes influencing device preference in different patient groups.

Main Methods:

  • A mail survey was administered to US residents with type 1 or 2 diabetes mellitus.
  • Respondents completed a 19-item questionnaire assessing expectations of VS and IIPD attributes on a 5-point Likert scale.

  • Statistical analyses, including chi-square tests, paired Student t tests, and regression analysis, were used to evaluate differences in preferences.

    • Main Results:

    • A total of 242 usable responses were analyzed, with 99 insulin users and 143 non-users.
    • Both insulin users and non-users showed significant regression coefficients (P < 0.001) for ease of use, activity interference, and social acceptability regarding device preference.
    • Overall preference leaned towards the insulin injection pen device (IIPD) for both groups.

    Conclusions:

    • The insulin injection pen device (IIPD) demonstrated a higher overall preference compared to the vial and syringe (VS) method among surveyed individuals.
    • Social acceptability emerged as the most significant predictor for IIPD preference.
    • For current insulin users, social acceptability and ease of use predicted VS preference. For non-users, discussions about VS should highlight activity interference and ease of use.
