Preparation, validation and user-testing of pictogram-based patient information leaflets for tuberculosis

Area of Science:

• Medical Education
• Public Health
• Graphic Design in Healthcare

Background:

• Effective patient education is crucial for managing Tuberculosis (TB) and achieving desired therapeutic outcomes.
• Verbal information delivery often leads to poor patient recall.
• Pictorial aids, or pictograms, offer a promising solution for patient knowledge dissemination.

Purpose of the Study:

• To develop and validate Pictogram-based Patient Information Leaflets (P-PILs) for Tuberculosis (TB) education.
• To assess the effectiveness of P-PILs in improving patient understanding of TB.
• To gather user opinions on the usability of P-PILs.

Main Methods:

• P-PILs were created using diverse information sources.
• Validated questionnaires assessed baseline and post-intervention knowledge.
• User opinions were collected after P-PIL administration.

Main Results:

• Significant improvement in knowledge scores post-P-PILs administration (62.67 to 91).
• Overall user opinion of P-PILs was positive (75% good, 25% average).

Conclusions:

• Validated P-PILs demonstrably enhance patient and volunteer knowledge of TB.
• P-PILs serve as an effective educational tool for Tuberculosis patients.
