Refinement of management effectively reduces dispensing errors: 12-year
experience from an outpatient pharmacy
Objective: Medication errors in hospital outpatient pharmacy have a
serious negative impact on people’s health and economy. To assess the
efficiency of 12-year refined management using PDCA cycle on reducing
the dispensing errors in a large-scale hospital outpatient pharmacy.
Methods: A retrospective study of dispensing errors was performed. Data
for dispensing errors, stocks and accounts management from 2008 to 2019
was collected from the electronic system and evaluated using direct
observation method. Results: The consistent rate of the stocks and
accounts was significantly increased (86.93% vs 99.54%, p <
0.05). A remarkable reduction of error rate was achieved (0.014% vs
0.0006%, p < 0.05) and the rate of dispensing errors was
significantly reduced (0.019% vs 0.000034%, p < 0.05).
Besides, the technicians improved themselves during this procedure.
Conclusion: the refined management using PDCA cycle was helpful to
prevent the dispensing errors and improve medication safety for
