Medication errors and risk areas in a critical care unit.

Area of Science:

• Critical Care Medicine
• Patient Safety
• Pharmacology

Background:

• Medication errors pose a significant threat to patient safety in critical care settings.
• Identifying the sources and patterns of these errors is crucial for developing effective interventions.

Purpose of the Study:

• To identify prevalent medication errors in critical care.
• To determine the causality and contributing factors of these errors.
• To pinpoint the highest-risk areas for medication errors.

Main Methods:

• A descriptive, longitudinal, and retrospective study design was employed.
• Systematic analysis of 2,634 medication dose units across prescription, transcription, and administration records.
• Data collected from 87 critically ill patients treated in 2018.

Main Results:

• The prescription phase exhibited the highest error rate (71%) and was the primary cause of errors (68%).
• Significant drug interactions were frequently observed.
• Key risk areas included antibiotic administration timing, dilution errors, medication concentration, administration speed of high-risk drugs, and nasogastric tube administration techniques.

Conclusions:

• A substantial number of medication errors persist in critical care, with many originating from prescription-stage issues.
• Nurse transcription serves as a vital intervention point, mitigating a considerable number of potential errors.
• Specific interventions are needed for time-dependent antibiotics, high-risk medications, and nasogastric tube administration to enhance patient safety.
