Objective:
To investigate the effects of a commercial electronic prescribing system on medical and medication errors.
Methods:
We conducted a retrospective before-and-after study in a teaching hospital by applying a U control chart to monthly error rates that were calculated from the number of both medical and medication errors divided by the number of patient days.
Results:
The process mean medical error rate from April 2008 to December 2010 was 0.0213±0.0004 (mean±SD), and consecutive data points after September in 2010 were under the process mean from April 2008 to December 2010. The process mean value from January 2011 to March 2012 was 0.0177±0.0005. A significant difference was seen in the process mean medical error rate between consecutive months before December 2010 and values after January 2011 (p<0.001). From April 2008 to December 2010, the process mean medication error rate was 0.0060±0.0002, and from January 2011 to March 2012, the mean value was 0.0045±0.0002 (p<0.001).
Conclusion:
We showed that it requires time to reach a significant reduction in medical and medication error rates after implementation of an electronic prescribing system. It is important to check and support ways to adjust to procedures involved in using a new system.
Insights
Implementing an electronic prescribing system significantly reduced medical and medication errors in a teaching hospital. While initial implementation requires time for adjustment, sustained use leads to improved patient safety outcomes.
Area of Science:
- Health Informatics
- Patient Safety
- Clinical Pharmacy
Background:
- Medical and medication errors pose significant risks to patient safety.
- Electronic prescribing systems (EPS) are designed to mitigate these errors.
- The impact of EPS implementation on error rates requires careful evaluation.
Purpose of the Study:
- To assess the effectiveness of a commercial electronic prescribing system in reducing medical and medication errors.
- To quantify the changes in error rates before and after EPS implementation.
Main Methods:
- A retrospective before-and-after study design was employed.
- Data were collected from a teaching hospital setting.
- U control charts analyzed monthly medical and medication error rates per patient day.
Main Results:
- A significant reduction in medical error rates was observed post-EPS implementation (p<0.001).
- Medication error rates also significantly decreased following EPS adoption (p<0.001).
- Sustained use of the EPS demonstrated a clear downward trend in both error types.
Conclusions:
- Electronic prescribing systems can lead to substantial reductions in medical and medication errors.
- A time lag exists between EPS implementation and significant error reduction.
- Ongoing support and procedural adjustments are crucial for maximizing EPS benefits.
