Abstract:
In this study, we established a methodology to calculate the rate of overlooking a dispensing error (inspecting error rate) as a new index for the purpose of determining dispensing error and malpractice rates. Using data obtained from analyses of these error rates at our and two other hospitals, an inspecting error rate was calculated for each institution. Our results showed that inspecting errors occurred at a frequency 3-5 times greater as compared to dispensing errors at each of the examined hospitals. We concluded that construction of a higher quality safety management system would be enabled by incorporation of an inspecting error rate as a new index to evaluate medical safety in regard to dispensing of medicines and managing inspection accuracy.
Insights
This study introduces the inspecting error rate to measure overlooked dispensing errors. This new metric reveals inspecting errors are 3-5 times more frequent than dispensing errors, enhancing medical safety management.
Area of Science:
- Pharmacy
- Patient Safety
- Healthcare Management
Background:
- Dispensing errors in pharmacies can lead to patient harm.
- Current methods for assessing dispensing accuracy may not fully capture all errors.
- There is a need for improved metrics to evaluate medication safety.
Purpose of the Study:
- To establish a methodology for calculating the inspecting error rate, defined as the rate of overlooking a dispensing error.
- To utilize this new index to determine dispensing error and malpractice rates.
- To evaluate the utility of the inspecting error rate in improving medical safety management.
Main Methods:
- Developed a methodology to calculate the inspecting error rate.
- Collected and analyzed dispensing and inspecting error data from three hospitals.
- Calculated the inspecting error rate for each participating institution.
Main Results:
- The inspecting error rate was calculated for each hospital.
- Inspecting errors were found to occur 3-5 times more frequently than dispensing errors across all examined hospitals.
- This highlights a significant gap in current error detection.
Conclusions:
- The inspecting error rate serves as a valuable new index for evaluating medical safety in medication dispensing.
- Incorporating this rate can lead to the development of higher quality safety management systems.
- Accurate management of inspection accuracy is crucial for patient safety.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
