Dosage calculation errors by nurses during administration can potentially be life threatening and cause great harm to patients. Medication errors occurred twice at the unit. An error rate of 43% in calculating intravenous medication by nurse was identified. The project was therefore initiated to improve the accuracy. The results of the analysis indicated that the error was largely due to lack of adequate training program on drug dosage calculation, the calculation process is too complex and time-consuming, frequent interruption by others, and low satisfaction with the calculation tool. The aim of this project was to reduce error in calculating drug dosage, decrease calculation time, and increase the satisfaction toward drug calculation tools. The improvement strategy included providing on-job training, building a Drug-Dosage Decision Supporting System and its operation guideline, providing a framework to avoid interference during drug dosage calculation, and establishing a double-checking system for dosage calculation in case of computer system failure. The results showed that the drug dosage calculation error rate reduced from 43% to 0%. The calculation time decreased from 6-10 minutes to 30-40 seconds. After the implementation of computer assisted program for dosage calculation, the satisfaction rate improved from 2.37 to 4.76. In conclusion, assisted system for dosage calculation could shorten calculation time and improve satisfaction among nursing staff. As a result, this system has also been implemented in other departments to ensure medication safety for patients. |
