Unexpected hypoglycemia in a critically ill patient.

Area of Science:

• Medical Safety
• Patient Care
• Clinical Risk Management

Background:

• Physicians often overlook medication errors in differential diagnoses due to lack of direct involvement in drug administration.
• Wrong medication administration is an understudied yet critical patient safety issue.

Observation:

• A case study details iatrogenic hypoglycemia caused by administering insulin instead of heparin to flush an arterial line.
• The institution's root-cause analysis and response to the adverse event were assessed.

Findings:

• Review of literature highlights strategies to prevent medication errors, including checklists and automated alerts.
• System changes like bar coding medications with patient and provider verification can prevent administration errors.

Implications:

• Healthcare organizations must foster a culture of safety, encouraging open discussion of errors.
• Implementing robust medication administration protocols is crucial for preventing adverse drug events.
