Medication error prevention by pharmacists--an Israeli solution.

Area of Science:

• Clinical Pharmacy
• Patient Safety
• Healthcare Quality Improvement

Background:

• Medication errors pose a significant threat to patient safety in hospital settings.
• Understanding the frequency and types of medication errors is crucial for developing effective interventions.

Purpose of the Study:

• To prospectively record medication order errors in a general Israeli hospital.
• To assess the impact of pharmacist interventions on preventing potential harm from medication errors.

Main Methods:

• A 6-month prospective study involving 160 detected medication order errors.
• Analysis of error types (prescription vs. therapy), principal error categories (dosage, interactions, drug, route, frequency), error rates per 100 patient days by department, and drug classes involved.
• Evaluation of pharmacist intervention effectiveness in modifying medication orders.

Main Results:

• Prescription errors constituted 60.6% and therapy errors 39.4% of all detected errors.
• Incorrect dosage (27.5%) and drug interactions (20%) were the most frequent error types.
• The highest medication error rates were observed in Hemato-Oncology (2.48) and Intensive Care (0.82) units.
• Anti-infective drugs were most frequently involved in errors (38.7%).
• Pharmacist interventions led to changes in 73.8% of error cases, primarily dosage or route adjustments.

Conclusions:

• The study likely underestimates the true incidence of medication errors.
• Identified problem areas and trends in medication errors provide a basis for implementing targeted improvements in drug use.
• Pharmacist involvement is key in mitigating medication errors and enhancing patient safety.
