Abstract：
BACKGROUND: Routine clinical biochemistry tests are crucial for clinical diagnostics and play a key role in enhancing outpatient turnover efficiency and patient satisfaction. This study aimed to implement Lean Six Sigma in the biochemistry laboratory of a hospital in China to improve efficiency and quality by reducing turnaround time.
METHODS: The study was conducted from January to December 2023, using the DMAIC (Define, Measure, Analyze, Improve, Control) framework, and employed tools such as the voice of the customer, Value Stream Mapping, \'5 whys\' technique, Nominal Group Technique, and Pareto chart.
RESULTS: The turnaround time for outpatient routine clinical biochemistry tests was reduced from 139 min to 58 min (p < 0.05), effectively increasing both patient and physician satisfaction.
CONCLUSIONS: Lean Six Sigma aimed to reduce the turnaround time for biochemical tests have significant advantages. This study confirms the effectiveness of Lean Six Sigma in a Chinese clinical laboratory setting and provides guidance for optimizing efficiency in global clinical laboratories with limited implementation experience, constrained technical and equipment resources, and high demand for medical diagnostics.

摘要：
背景：常规临床生化检查对于临床诊断至关重要，在提高门诊周转效率和患者满意度方面发挥着关键作用。本研究旨在在中国一家医院的生化实验室实施精益六西格玛，通过减少周转时间来提高效率和质量。
方法：该研究于2023年1月至12月进行，使用DMAIC（定义，Measure,分析,改善,控制）框架，和使用的工具，如客户的声音，值流映射,\'5个为什么\'技术，标称成组技术，和帕累托图表。
结果：门诊常规临床生化检查的周转时间从139分钟减少到58分钟（p<0.05），有效提高患者和医生的满意度。
结论：精益六西格玛旨在减少生化测试的周转时间具有显着的优势。这项研究证实了精益六西格玛在中国临床实验室环境中的有效性，并为在实施经验有限的全球临床实验室中优化效率提供了指导。技术和设备资源受限，以及对医疗诊断的高需求。
