基于约束理论优化预约检查流程的应用研究

Applied research of appointment checkup process optimization based on the theory of constraints

目的探讨基于约束理论优化后的预约检查流程在缩短检查预约时间中的应用效果。方法选取山西医科大学第一医院2017年3月至2018年2月进行超声、核磁、CT检查的患者为研究对象。研究第一阶段应用约束理论进行医技检查现状调研、原因分析；第二阶段根据调研结果进行流程优化，并对优化前后医技检查预约时间进行比较。结果在多部门配合下，流程优化后医院超声平均最长预约时间由3．74天缩减为1．32天；核磁最长预约时间由3．74天缩减为1．33天；CT最长预约时间由2．62天缩减为1．55天，并在持续改进阶段达到开出检查单次日即可完成检查的目标。结论基于约束理论优化后的医技检查预约流程可以有效缩短检查预约时间，促进医疗资源利用最大化和服务效果最优化。

Objective To discuss the effect of the appointment checkup process optimized with the theory of constraints in shortening the appointment waiting time. Methods The patients who underwent uhrasonography, magnetic resonance imaging examination, and CT examinations were selected from the First Hospital of Shanxi Medical University from March 2017 to February 2018. Firstly, we applied the theory of constraints to investigate and analyze the status of medical technology examinations. Secondly, we optimized the process according to the results of the investigation. Finally, we compared the appointment duration of medical examinations before and after the optimization. Results Thanks to support of departments involved, the longest uhrasonography appointment waiting time was reduced from 3.74 days to 1.32 days. The longest appointment time for magnetic resonance imaging examination was reduced from 3.74 days to 1.33 days. The longest appointment waiting time for CT was reduced from 2. 62 days to 1. 55 days, and the goal of completing the checkup the day after the prescription was reached in the continuous improvement phase. Conclusions The optimization of the medical technology examination appointment process based on the constraint theory can effectively shorten the checkup appointment duration, maximize utilization of medical resources and optimize the services.
