MEDICATION ERRORS: A PROSPECTIVE STUDY IN MOHAMED V MILITARY TEACHING HOSPITAL, RABAT, MOROCCO

Medication errors (MEs) are preventable events that may cause or lead to inappropriate medication use or patient harm. Annually 98,000 patients die because of avoidable MEs, and it is considered a financial burden on public health organizations. The purpose of our study was to examine the incidence rate, types, and causes of medication errors. We conducted a prospective, descriptive study from 1st November 2018 to 1st March 2019 at Mohammed V Military Teaching Hospital in Morocco. We performed prescriptions analysis for all patients, and the proper corrective measures were taken. We analyzed 19,200 prescriptions during the study period and made 2,152 (11.20%) pharmaceutical interventions (PI). We identified 752 medication errors (34.94%) of the total PIs) in 562 patients, with an incidence rate of 3.91%. The number of medication errors was higher in men than in women. The most frequent medication errors were: drug interaction errors, dosage or concentration errors, and dose errors. Bearing in mind the outcomes of our study, it is crucial to raise awareness among healthcare professionals of the significance of medication errors. Further investigations are required to fully understand and establish measures to reduce the prevalence rate of medication errors.
