Self-administration medication errors at home and its predictors among illiterate and low-literate community-dwelling older adults with polypharmacy: A negative binomial hierarchical regression.

Further studies to identify the role of patients, clinicians, procedures, and systems in developing MSEs as interconnected components are needed.
