Objective: This systematic review aims to investigate the role and responsibilities of pharmacists in prevention
of medication errors. Also to evaluate pharmacist-centered strategies that has an impact in medication error reduction and
Method: A search was conducted through the following databases PubMed Central, Scopus, Trip, Prospero, Medline and
Google Scholar using terms related to “medication errors prevention” or “pharmacist-related errors”. Other search terms
included “pharmacis t(s)”, “prevention”, “medication error (s)”, “dispensing error (s)”, “drug incidence (s)”, “medication
malpractice (s)”. Included studies were prospective and retrospective cohort, case-control and cross-sectional full-text
studies published in the last 10 years (2010-2020). The review team screened the articles for inclusion criteria and
evaluated the quality of the articles. The PRISMA Guidelines were used to report the selected articles and screening
process. Then, the articles was sent to a third independent reviewer for quality assessment using the STROBE Checklist.
Results: A clinical pharmacist’s duties are to supervise the medication treatment of admitted patients and to notify the
healthcare team when a discrepancy is found. A total of seven reviewed studies highlighted the importance and positive
impact of increasing the number of the clinical pharmacist’s interventions. Literature showed that average of 64.9% of
medication discrepancies happen during patient discharge, highlighting the necessity of a clinical pharmacist intervention
at that stage. The systematic review focused on the significant impact of clinical pharmacist role in preventing errors
(studies reported=5); encouraging pharmacist-led education to increase medication error awareness (studies reported =5),
incorporating better and innovative pharmacy-related work approaches (studies reported =4); and implementing
appropriate and secured policies for medication error reporting (studies reported =1). The screened literature highlighted
the significant reduction in the number of medication errors and an increase in medication error identification and
awareness. These findings suggest the crucial role of pharmacist in healthcare policies for the prevention of medication
errors and patient safety.
Conclusion: This systematic review suggests multiple pharmacist-centered strategies that have been implemented in
several studies showing the positive impact in the reduction and prevention of medication errors commenced by not only
the pharmacist but the rest of the healthcare team.
