Medical Product Labeling: The Evaluation of Latex Glove Warnings in a Realistic Setting

Healthcare workers sometimes develop a deadly allergic reaction through repeated exposure to proteins in latex gloves. Although die latex glove industry apparently developed warnings to alert healthcare workers to the hazards associated with exposure to latex, none of these warnings actually appeared on latex glove packaging. This field study evaluated three label configurations. The first configuration merely stated that the gloves contain natural rubber latex (content statement). A second configuration mirrored current labeling and contained both the content statement and the admonition that natural rubber latex can cause allergic reactions. A third label developed specifically for this study comported to existing warnings guidelines (ANSI Z-535). Participants examined one of the three boxes and were men asked to complete a questionnaire gauging their opinions and perceptions regarding the labeling. Results showed that the ANSI warning was rated as more noticeable and more effective than the other label configurations. Well-designed instructional warnings can be an effective method of informing workers of the significant risks associated with exposure to latex. The informational component of warnings labeling is particularly critical for apparently benign products that bear a hidden hazard.
