Older adults found child-resistant medication containers difficult to open. Non-child-resistant options are easier for seniors, improving medication access when child safety isn

Area of Science:

  • Gerontology
  • Human Factors Engineering
  • Pharmaceutical Packaging

Background:

  • Medication adherence is crucial for older adults' health.
  • Many medication containers feature child-resistant closures (CRCs) that may pose challenges for seniors.
  • Accessibility of medications is a significant concern for the elderly population.

Purpose of the Study:

  • To assess the usability and difficulty elderly individuals experience with various medication container types.
  • To compare the performance of child-resistant versus non-child-resistant medication packaging for older adults.
  • To identify specific container designs that present challenges for seniors.

Main Methods:

  • 50 noninstitutionalized men and women over 60 years old participated.

  • Participants were timed while opening 15 different medication containers, including pill bottles, liquid bottles, and other packaging like nitroglycerin patches.
  • Both child-resistant and non-child-resistant containers were tested.

    • Main Results:

    • All participants could open non-child-resistant containers.
    • No child-resistant container could be opened by all participants.
    • Significant variations in success rates and opening times were observed among different child-resistant container designs.
    • Qualitative feedback from participants provided insights into usability issues.

    Conclusions:

    • Child-resistant medication containers can significantly hinder older adults' ability to access their medications.
    • Container design plays a critical role in usability for the elderly population.
    • Non-child-resistant containers are the preferred choice for older adults when child safety is not a primary concern, enhancing medication adherence and independence.
