Impact of computerized physician order entry on medication errors.

Area of Science:

• Geriatric Medicine
• Health Informatics
• Patient Safety

Background:

• Limited data exists on the impact of electronic health records on medication errors in acute geriatric care.
• Medication errors pose a significant risk to patient safety, especially in vulnerable geriatric populations.

Purpose of the Study:

• To evaluate the effect of implementing computerized provider order entry (CPOE) systems on the frequency and severity of medication errors in acute geriatric patients.
• To compare medication error rates and characteristics before and after CPOE implementation.

Main Methods:

• An analytical, descriptive pre-post study design was employed over six years.
• Medication errors were identified using voluntary reporting, the IR2 report form, Global Trigger Tool, and pharmacy walk rounds.
• Error severity was categorized using the National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP) index.

Main Results:

• A total of 1887 medication errors were detected, with prescription errors accounting for 27.6%.
• Adverse drug events were more frequent with electronic records (2.07 times) compared to handwritten systems, particularly for antibiotics, antipyretics, and opiates.
• However, serious medication errors decreased significantly with electronic records, including drug omission (46.8 times less frequent) and wrong dose (10.53 times less frequent).

Conclusions:

• The implementation of electronic clinical records in acute geriatric care was associated with an increase in the overall frequency of medication errors.
• A notable decline in the severity of detected medication errors was observed with the electronic record system.
• Continuous monitoring and evaluation of electronic health record systems are crucial to mitigate risks and enhance patient safety in geriatric populations.
