Health literacy and the emergency room
Older age, less education, and lower income were all associated with reduced functional health literacy. Associations with ethnicity, race, and language were not statistically significant in the multivariate analysis (i.e. after correcting for other variables).
The authors note "In this sample, one-quarter of ED patients would be expected to have difficulty understanding health materials and following prescribed treatment regimens. Advanced age and low socioeconomic status were independently associated with limited health literacy. The ability of a significant subgroup of ED patients to understand health information, especially during illness or injury, requires further study."
One potential limitation that comes to mind - a cross-sectional study gives just a snapshot, rather than a longitudinal assessment -- the questionnaire results reflect each individual's completion of a brief test during their stay in the ED setting, which is a fairly difficult environment given the complexity of this kind of healthcare encounter (stress of the health condition, urgency, family issues, financial considerations, etc.). The competing concerns of the environment may shift individual test results downward. If you tested the same person while they were going to a routine visit at their doctor, their results may be different.
On the other hand, the methods of the current study would seem to give an accurate picture of functional health literacy at the moment of crisis, which speaks more to how people may (or may not) be able to handle, process, and retain information in that particular setting.
So, having a librarian stationed in the ED might not, then, be a good idea, but do other strategies come to mind for aiding individuals with lower health literacy in this setting?
