Abstract Objective To explore the effect of six sigma management in reducing the average length of stay of patients with lumbar disc herniation. Methods The study investigated the potential causes which extended the length of hospital stay, found the highly relevant and controllable factors, clarified the key points, and then developed the targeted solutions to improve it through the DMAIC process according to six sigma management. Results The study detected the key factors affecting the length of stay which included hospital consultation, holiday waiting, treatment planning, elderly patients, postoperative complications, and so on. The average hospital stay of patients with lumbar disc herniation dropped from the original 8.83±4.23days to 7.12±3.16 days after the improvement. Conclusion Six sigma management could be applied to identify the key factors, modify the hospital diagnosis and treatment process, improve work efficiency, and shorten the average length of stay of patients with LDH.
