Development of a hospital pharmacist led re-evaluation of medication errors

Pdf

Why was it done?

All errors, whether involving medication or not, are required to be reported and classified in the hospital reporting system. However, the system is poorly adapted for medication management and lacks the relevant terms. This results in the same type of error being classified in various ways, making systematic quality improvement difficult. A pilot study confirmed the system’s shortcomings, after which a new medication management process was developed and evaluated.

What was done?

The existing process for classifying medication errors was supplemented with a new process in which hospital pharmacists reclassified medication errors detected in the reporting system. The reclassification was based on a predefined medication management process.

How was it done?

A medication management process was developed in collaboration with specialist nurses and in accordance with applicable regulations and policies. The process consisted of the following activities: 1) Prescription, 2) Ordering/Delivery, 3) Storage/Narcotics Control, 4) Preparation, 5) Handover/Administration, 6) Medicines information in transitions of care, 7) Follow-up of treatment, and 8) Miscellaneous. The process was validated by having four hospital pharmacists independently classify 176 medication errors. Consistency in the assessment was evaluated, and the process was corrected as needed. All medication errors classified as medication-related in 2022 or containing the word “medication” in free text were thereafter exported from the reporting tool to Microsoft Excel and then into a data processing and performance monitoring tool for further analysis.

What has been achieved?

A total of 756 medication errors were identified in the reporting tool, distributed across 65 different activities. Hospital pharmacists identified an additional 305 errors through free-text searches that had not been reported as medication-related. A total of 1,061 medication errors (756+305) were reclassified and grouped into eight activities. The highest risk of errors was associated with the preparation (19%), followed by storage/narcotics control (18%), and prescription (17%). The new process, involving hospital pharmacists in classification, creates conditions for a more systematic approach to medication errors. The pilot project was presented at the hospital’s themed day for World Patient Safety Day 2022.

What next?

Discussions have been initiated with system developers to improve the reporting tool. Discussions with hospital management will be initiated with the goal of creating a structure in which hospital pharmacists have an active role in the hospital’s work on patient safety related to medication.
