Abstract
Context: Dispensing errors pose a significant risk to patient safety and remain a primary concern in the practice of pharmacy.
Aims: To assess the prevalence of dispensing errors and identify associated factors among community pharmacists in Jordan.
Methods: A cross-sectional study was conducted among 202 community pharmacists using a validated questionnaire. The sample size was based on Green’s rule (n = 50 + 8*12 predictors). Quantile regression was employed to examine predictors of error frequency.
Results: Common contributing factors included similar medication names (61.4%), unreadable prescriptions (67.3%), and incomplete prescriptions (66.3%). Higher error frequencies were observed among employee pharmacists (β = 2.333; p = 0.007) and male pharmacists (β = -1.667; p = 0.01).
Conclusions: Dispensing errors remain prevalent. Employment status and gender were significantly associated with error frequency. Targeted interventions and policy reforms are recommended to reduce errors and improve patient safety.
Keywords: community pharmacist; dispensing error; frequency; prescription: Jordan.

Resumen
Contexto: Los errores de dispensación suponen un riesgo significativo para la seguridad del paciente y siguen siendo una preocupación fundamental en la práctica farmacéutica.
Objetivos: Evaluar la prevalencia de errores de dispensación e identificar los factores asociados entre los farmacéuticos comunitarios de Jordania.
Métodos: Se realizó un estudio transversal con 202 farmacéuticos comunitarios mediante un cuestionario validado. El tamaño de la muestra se basó en la regla de Green (n = 50 + 8*12 predictores). Se empleó una regresión cuantil para examinar los predictores de la frecuencia de errores.
Resultados: Los factores contribuyentes comunes incluyeron nombres de medicamentos similares (61,4%), recetas ilegibles (67,3%) y recetas incompletas (66,3%). Se observaron mayores frecuencias de errores entre los farmacéuticos empleados (β = 2,333; p = 0,007) y los farmacéuticos varones (β = -1,667; p = 0,01).
Conclusiones: Los errores de dispensación siguen siendo prevalentes. La situación laboral y el género se asociaron significativamente con la frecuencia de errores. Se recomiendan intervenciones específicas y reformas políticas para reducir los errores y mejorar la seguridad del paciente.
Palabras Clave: error de dispensación; farmacéutico comunitario; frecuencia; prescripción; Jordania.
