Registered Nurses' Knowledge of and Experience with Health Literacy.

Background: Limited skill in health literacy is a global issue. Variation in health literacy skills within societies is a source of health inequality unless health care providers apply health literacy practices to effectively communicate with all clients. Objective: This study examined Iranian registered nurses' knowledge of and experience with health literacy practices. Methods: This cross-sectional study provides a quantitative description of knowledge of and experience with health literacy practices. Using a rigorous process, we adapted the Health Literacy Knowledge and Experience Survey to collect data from the participants, who were 190 registered nurses working in Tehran, Iran. Key Results: Findings identify gaps in participants' knowledge and experience with health literacy practices. Knowledge deficits are most noticeable in standards to create written materials, screening tools to identify limited health literacy, and the Teach-Back strategies to determine people's understanding. Limited experience is prominent in using health literacy screening tools, evaluating written health information, and applying technologies to provide health information. Our multivariate analysis suggests participants who reported more interaction with health care professionals for personal reasons scored higher in knowledge of health literacy practices. Conclusions: This study indicated that registered nurses in Iran do not have adequate knowledge and experience regarding health literacy practices. Addressing this issue is fundamental to promoting health equity. Future investigations should identify both barriers and facilitators for nurses to apply health literacy practices. Plain Language Summary: Health literacy practices enable health care professionals to offer understandable health information to all people and contribute to health equity. We surveyed 190 registered nurses in Iran to assess their knowledge of and experience with health literacy practices. The findings will be a guide to create interventions to improve registered nurses' knowledge of these practices and to use them to communicate clearly with clients.
