基于价值流图技术的静脉用药调配中心工作流程优化研究OA

AIM To explore the application of the lean management tool,value stream mapping(VSM),in optimizing workflows of the pharmacy intravenous admixture service(PIVAS),and to evaluate its effectiveness in improving operational efficiency and quality control.METHODS Based on the VSM analytical framework,a five-step approach was employed:current state mapping,waste identification,future state design,implementation of improvements,and continuous refinement.A systematic optimization of the PIVAS workflow was conducted.The impact of the changes was assessed using key performance indicators,including labor cost,production cycle time,value stream efficiency,and admixture accuracy.RESULTS The current state map revealed the primary bottleneck at the drug mixing stage,along with multiple non-value-added activities such as premature processing,unnecessary motions,excessive processing,production efficiency,and inefficient handoffs between process stages.Based on these findings,a future state map was developed and a series of lean interventions were implemented,including the introduction of semi-automated equipment,process reengineering,standardization of operations,and role consolidation.Post-optimization metrics showed notable improvements:labor costs decreased by 20.00％,work-in-process inventory decreased by 13.84％,the production cycle time shortened by 28.57％,value stream efficiency increased by 18.49％,production efficiency improved by 75.06％,and admixture accuracy improved by 0.05％.CONCLUSION As a visual and systematic lean management tool,VSM can effectively identify process bottlenecks and uncover non-value-adding activities,helping to achieve multiple goals including cost control,efficiency improvement,and quality assurance,and holds broad potential for promotion and application.
