Abstract:
Background: Errors may happen during the dispensing process and result in patient harm.
Dispensing errors are preventable by error-proofing the system together with vigilance by
pharmacists. Objectives: To assess awareness and perceptions on the prevalence, nature and
possible causes of dispensing errors among pharmacists in selected hospitals in Sri Lanka.
Methodology: The study was a descriptive, cross sectional and multi-center study where all
pharmacists in three hospitals (one tertiary care and two secondary care) in three different
districts were interviewed (N=48). A pretested and validated (content and face) interviewer
administered questionnaire was used to collect data and data were analyzed using IBM SPSS
(version 25.0). The questionnaire assessed perceptions of pharmacists on the prevalence, types,
and possible causes of dispensing errors. Results: Most pharmacists were within the age 20-
40 years (67%) and 54% were women. Most pharmacists agreed that dispensing errors could
happen (90%) in Sri Lanka while the rest had ‘no idea’ about dispensing errors. The majority
(62%) agreed that they are prone to commit a dispensing error in the current hospital setup.
Over 90% of pharmacists correctly identified the different types of dispensing errors. However,
missing or wrong medicine information on dispensing labels, and dispensing the wrong
quantity of medicine units were not considered as dispensing errors by a few. Among many
reasons, pharmacists perceived, illegible handwriting on prescriptions (92%), similar or
confusing medicine names (85%), dispensing of incomplete prescriptions (83%), and over
worked pharmacists (81%) as main causes for dispensing errors in Sri Lanka. Conclusions:
Most pharmacists in Sri Lanka were aware of the nature and prevalence of dispensing errors
and highlighted numerous system issues that may cause them. These concerns must be urgently
addressed by medical administrators to ensure medication safety of patients
