Background

The high prevalence of limited health literacy among patients threatens the success of secure electronic messaging between patients from diverse populations and their providers.

Objective

The purpose of this study is to generate hypotheses about the readability of patient and provider electronic messages.

Methods

We collected 31 patient-provider e-mail exchanges (n = 119 total messages) from a safety-net primary care clinic. We compared the messages' mean word count and Flesch-Kincaid Grade Levels (FKGLs), calculated the frequency of provider messages below an FKGL = 8, and assessed readability concordance between patients' and providers' messages.

Results

Patients used more words in their initial e-mails compared to providers, but the FKGLs were similar, and 68% of provider messages were written below an FKGL = 8. Of 31 exchanges, 9 (29%) contained at least one patient message with an FKGL > 3 grade levels lower than the corresponding provider message(s).

Conclusion

Our study demonstrates that most providers are able to respond to patient electronic messages with a matching reading level.
