Reported medication errors after introducing an electronic medication management system.

Area of Science:

• Health Informatics
• Patient Safety
• Clinical Pharmacy

Background:

• Computerized medication management systems (CMMS) are recognized for enhancing medication safety.
• However, CMMS implementation can introduce novel challenges and opportunities for medication errors within healthcare settings.

Purpose of the Study:

• To investigate the impact of implementing an electronic medication management system (eMMS) on the nature of reported medication errors.
• To compare medication error profiles between a site using a traditional pen-and-paper system and a site utilizing an eMMS.

Main Methods:

• A retrospective analysis of 359 incident reports from two hospital sites over a 12-month period.
• Site A employed a conventional pen-and-paper medication management system.
• Site B utilized a newly introduced computerized medication management system.

Main Results:

• The majority of medication errors occurred during nurse administration (71.5%) and prescribing (16.4%).
• Site A (pen-and-paper) reported omission errors most frequently (33%), while Site B (eMMS) reported wrong documentation errors most frequently (24.2%).
• Site B demonstrated a higher proportion of prescribing errors and fewer nurse administration errors compared to Site A.

Conclusions:

• The introduction of an eMMS alters the types of medication errors reported, shifting the pattern from traditional issues like omissions.
• Findings offer valuable insights into the evolving landscape of medication errors during eMMS implementation.
• Clinical practice should consider targeted support for physician prescribing within eMMS environments.
