Summary
Medication errors occurred in 7.7% of prescriptions, with dosage errors being most common. Implementing systematic controls like the Unit Dose Drug Distribution System can prevent errors from reaching patients.
Area of Science:
- Pharmacology
- Patient Safety
- Health Informatics
Background:
- Prescribing medication errors pose a significant risk to patient safety.
- Accurate identification and classification of these errors are crucial for developing effective prevention strategies.
Purpose of the Study:
- To determine the incidence and types of prescribing medication errors.
- To identify methods for preventing medication errors from reaching patients.
Main Methods:
- Prospective study analyzing 4951 prescriptions over 25 weeks.
- Medication errors classified as incorrect dose, interval, duplication, and drug interactions.
- Prescribing data compared with Croatian literature and AHFS drug databases.
Main Results:
- Overall medication error incidence was 7.7% (379 errors).
- Dosage errors were most frequent, followed by incorrect interval, duplication, and drug interactions.
- Clinically significant drug interactions were rare (0.2%) compared to potential interactions (7.2%).
Conclusions:
- Systematic control of prescribed therapies is essential.
- The Unit Dose Drug Distribution System can enhance medication safety.
- Establishing medication error reporting programs at hospital and national levels is recommended.
