New package insert designs significantly improved patient comprehension of medication information, especially dosage and side effect details. These optimized formats enhance patient understanding and adherence to treatment. Keywords: patient comprehension, medication information, dosage instructions, side effects.

Area of Science:

  • Pharmaceutical Sciences
  • Health Communication
  • Patient Education

Background:

  • Patient package inserts are crucial for medication adherence and safety.
  • Despite efforts, current package inserts often lack patient-oriented clarity.
  • The Survey Package Insert Test (PAINT) was initiated to address these issues.

Purpose of the Study:

  • To evaluate the availability and comprehensibility of information on original versus redesigned package inserts.
  • To compare patient understanding of medication details between standard and model package insert versions.

Main Methods:

  • A cross-over study design involving 1,105 participants.
  • Participants completed a 15-question survey on both original and model package inserts.
  • A 4-week interval separated the assessment of each insert type.

Main Results:

  • Model package inserts yielded significantly higher correct answers (92.6-94.4%) compared to originals (74.7-85.8%).
  • Comprehension issues in original inserts included dosage units (active substance vs. tablet/volume) and vague side effect descriptions.
  • Understanding of side effect countermeasures was also problematic in original inserts.

Conclusions:

  • Optimizing package inserts is essential for improving patient understanding of crucial medication information.
  • Specific improvements in dosage instructions and side effect information are achievable and necessary.
  • Recommendations include quantifying doses, using tables, providing concise information, and avoiding non-quantifiable statements.
