Limited English-language health literacy (LEHL) and disadvantaged socioeconomic position (dSEP) have been shown to increase risk of adverse events and near misses. Using data from the 2017 Institute for Healthcare Improvement-National Patient Safety Foundation study, researchers found, while respondents with LEHL or dSEP experienced diagnostic errors at the same rate as their counterparts, they were more likely to report unique contributing factors and more long-term emotional, physical, and financial harm.
