Medication errors--an enduring problem for children and elderly patients.

Area of Science:

• Pharmacovigilance and Toxicology
• Patient Safety Research
• Healthcare Quality Improvement

Background:

• Medication errors pose a significant threat to patient safety, necessitating ongoing analysis of their types and causes.
• Toxicological consultations are crucial for managing adverse drug events and understanding medication error patterns.

Purpose of the Study:

• To investigate the types and underlying reasons for medication errors reported to the Czech Toxicological Information Centre (TIC).
• To identify healthcare professionals involved and the patient demographics most affected by these errors.

Main Methods:

• Retrospective analysis of medication error inquiries from the TIC database between 2000 and 2010.
• Categorization of errors by type (dosage, medication, route), involved drug classes, and healthcare professional responsibility.

Main Results:

• 0.5% of pharmaceutical calls (215/44,344) were identified as medication errors, affecting 130 children and 85 adults.
• Improper dosage (60.9%), wrong medication (19.3%), and incorrect administration route (12.9%) were the most frequent errors.
• Nurses (43.0%), physicians (36.8%), and pharmacists (20.2%) were implicated; high-risk drugs included CNS agents, antibiotics, and respiratory medications.

Conclusions:

• Medication error trends remained stable over 11 years, with persistent high-risk groups.
• Children under five and elderly individuals on chronic medication represent key populations for targeted risk reduction efforts.
• Ensuring correct dosage adjustment in children and adequate medication control in the elderly are critical for preventing errors.
