Feasibility of Symbolic Directions on Prescription Labels

Abstract

French

This project presents the results of a study designed to evaluate the usefulness of graphic labels in assisting functionally illiterate patients to understand how and when to take medication. The project's results indicate that comprehension of symbolic directions did not increase as rapidly as comprehension of typed directions. Symbolic directions did, however, reduce the variation in interpretation of directions among patients with a 0–4 grade education. Neither age, nor sex, nor the order of label presentation affected level of comprehension of typed or symbolic prescription labels.

The results of this study indicate that use of symbols may not be the sole answer to the problem of assisting patients with inadequate reading abilities. Symbolic prescription directions should be evaluated before their use. Then, when used, they should be accompanied by oral reinforcement.
