Exploring discharge prescribing errors and their propagation post-discharge: an observational study.

Area of Science:

• Pharmacology
• Patient Safety
• Health Services Research

Background:

• Discharge prescribing errors are frequent but their persistence post-discharge is poorly understood.
• Medication errors after hospital discharge pose a significant risk to patient health.
• Understanding the link between prescribing and post-discharge errors is vital for improving care.

Purpose of the Study:

• To investigate the relationship between discharge prescribing errors and medication errors occurring after hospital discharge.
• To identify the incidence, types, and potential severity of post-discharge medication errors.
• To determine which types of prescribing errors are most likely to persist post-discharge.

Main Methods:

• A prospective observational study was conducted at an adult academic hospital in Ireland.
• Patients with multiple chronic medications, undergoing medication changes, and discharged home were included.
• Discharge prescriptions were compared against gold-standard medication lists and patient use was verified post-discharge.

Main Results:

• Over 43% of patients experienced post-discharge medication errors, with most at risk of moderate harm.
• The majority of post-discharge errors (86%) were persistent discharge prescribing errors.
• Common persistent errors included unintentional prescription of stopped medications, dose/frequency/formulation errors, and omissions.

Conclusions:

• A significant proportion of discharge prescribing errors persist post-discharge, leading to patient harm.
• Effective discharge medication reconciliation processes are essential to minimize these errors.
• Improved medication management post-hospitalization is needed to ensure patient safety and optimize therapeutic outcomes.
