Objective:
Assessing the impact of introducing preoperative pharmaceutical care consultations by analyzing the severity of prevented medication errors (MEs) and their potential effects on the surgical process.
Methods:
Preoperative pharmaceutical care consultation was implemented in our hospital to assess the preoperative medication management of surgical patients between the pre-anesthesia consultation and the day of surgery. Pharmacists evaluated the appropriateness of medication management based on a consensus multidisciplinary institutional protocol. All errors identified between 2016 and 2020 were analyzed, and their severity and potential impact on surgery were standardized. A list of therapeutic groups was created to prioritize patients for consultations.
Results:
During the study period, 3,105 patients attended the consultations and 1,179 MEs were prevented. According to severity, 30.6% of MEs were classified as category E and 26.2% as D. The Number Needed to Treat to prevent a category E or higher ME (indicating potential harm to patients) was 5 patients. About 14.84% of MEs belonged to the prioritized drug groups. One hundred and thirteen errors would have resulted in a surgery delay of more than 24 h, and 175 errors were classified as G-H (irreversible damage).
Conclusions:
This study highlights the effectiveness of pharmaceutical care consultations in preventing MEs and improving surgical outcomes.
