Dispensing errors in community pharmacies in the United Arab Emirates: investigating incidence, types, severity, and...

Medication dispensing is a fundamental function of community pharmacies, and errors that occur during the dispensing process are a major threat to patient safety. However, to date there has been no national study of medication dispensing errors in the United Arab Emirates (UAE).

The study aimed to investigate the incidence, types, clinical significance, causes and predictors of medication dispensing errors.

The study was conducted in randomly selected community pharmacies (n=350) across all regions of UAE over six months using a mixed-method approach, incorporating prospective disguised observation of dispensing errors and interviews with pharmacists regarding the causes of errors. A multidisciplinary committee, which included an otolaryngologist, a general practitioner and a clinical pharmacist, evaluated the severity of errors. SPSS (Version 26) was used for data analysis.

The overall rate of medication dispensing errors was 6.7% (n=30912/ 464222), of which 2.6% (n=12274/464222) were prescription-related errors and 4.1% (n= 18638/464222) pharmacist counselling errors. The most common type of prescription-related errors was wrong quantity (30.0%), whereas the most common pharmacist counselling error was wrong drug (32.1%). The majority of errors were caused by medicine replaced with near expire one (24.7%) followed by look-alike/sound-alike drugs (22.3%). The majority of errors were moderate (46.8%) and minor (44.5%); 8.7% were serious errors. Predictors of medication dispensing errors were: grade A pharmacies (dispensing ≥ 60 prescriptions a day (OR 2.1; 95%CI 1.4-3.6; p=0.03) and prescriptions containing ≥4 medication orders (OR 2.5; 95%CI 1.7-4.3; p=0.01).

Medication dispensing errors are common in the UAE and our findings can be generalised and considered as a reference to launch training programmes on safe medication dispensing practice.
