Characteristics associated with postdischarge medication errors.

Area of Science:

• Pharmacology and Patient Safety
• Health Literacy Research
• Medical Decision Making

Background:

• Medication errors after hospital discharge pose a significant threat to patient safety and treatment efficacy.
• Understanding patient-specific factors influencing medication adherence and accuracy is crucial for effective care transitions.

Purpose of the Study:

• To investigate the association between patient-related factors and medication errors following hospital discharge.
• To identify specific patient characteristics that predict discrepancies in medication management post-discharge.

Main Methods:

• The Vanderbilt Inpatient Cohort Study analyzed adults hospitalized with acute coronary syndromes or heart failure.
• Key patient factors including health literacy, numeracy, and social support were assessed.
• Binomial logistic regression identified predictors of medication list discordance.

Main Results:

• Approximately 51.4% of patients exhibited medication list discrepancies post-discharge.
• Higher subjective numeracy was linked to fewer discordant medications (OR, 0.81).
• For cardiac medications, enhanced health literacy, numeracy, and being female reduced misunderstandings in indication, dose, or frequency.

Conclusions:

• Medication errors are prevalent in nearly half of patients after discharge.
• Lower numeracy and health literacy are significant risk factors for post-discharge medication errors.
• Targeted interventions to improve numeracy and health literacy may reduce medication errors.
