Analysing electronic prescribing data to detect potential undocumented adverse reactions to medications

Area of Science:

• Clinical Informatics
• Patient Safety
• Pharmacovigilance

Background:

• Medication safety is paramount in healthcare settings.
• Inaccurate allergy documentation can lead to adverse drug events.
• Electronic prescribing systems offer opportunities to improve medication safety.

Purpose of the Study:

• To identify cases where medications were stopped due to adverse/allergic reactions.
• To determine if patients' allergy status was appropriately updated in the electronic system.
• To assess the impact on patient safety within a hospital setting.

Main Methods:

• Retrieved data on all medications discontinued due to allergic reactions over three years.
• Investigated instances where discontinued medications were not reflected in patient allergy records.
• Reviewed patient charts to confirm genuine allergic reactions.

Main Results:

• 434 medications were discontinued due to drug allergies during the study period.
• 26 cases revealed documented drug reactions that were not added to patient allergy histories.
• This highlights a gap in updating patient allergy status in electronic systems.

Conclusions:

• Electronic prescribing and medicines administration systems contain valuable data for process analysis.
• Analyzing this data can reveal system and process deficiencies.
• Leveraging such data can enhance electronic systems and improve overall patient safety.
