Health Literacy,Medication Errors,and Health Outcomes: Is There a Relationship?

Abstract

Purpose

To definitively examine the relationship between health literacy and medication errors by reviewing the existing literature.

Summary

Over the past decade, our understanding of health literacy and its impact on society has greatly evolved, with research showing that patients with inadequate literacy levels are often subjected to inferior health outcomes. While several theoretical reasons exist to explain this suboptimal situation, one possible explanation is that patients with lower literacy levels do not have the skills necessary to effectively navigate the medication use process thus potentially leading to an increase in medication errors. Although the main focus of this article is to search for a direct association between literacy and medication errors, we also sought to identify an indirect relationship by evaluating previous studies, which explore the effects of literacy on health outcomes.

Conclusion

While we identified numerous studies that suggest that low literacy adversely affected patient outcomes, no study was found that directly linked low-health literacy to medication errors. The authors conclude that additional studies are needed to clarify this relationship.
