• Lean Six Sigma

Objectives This study aims to reduce cesarean section rate and increase rate of vaginal delivery.
Methods By using Lean Six Sigma (LSS) methodology, the cesarean section rate was investigated and analyzed through a 5-phase roadmap consisting of Define, Measure, Analyze, Improve, and Control. The principal causes of cesarean section were identified, improvement measures were implemented, and the rate of cesarean section before and after intervention was compared.
Results After patients with a valid medical reason for cesarean were excluded, the main causes of cesarean section were maternal request, labor pain, parturient women assessment, and labor observation. A series of measures was implemented, including an improved parturient women assessment system, strengthened pregnancy nutrition guidance, implementation of painless labor techniques, enhanced midwifery team building, and promotion of childbirth-assist skills. Ten months after introduction of the improvement measures, the cesarean section rate decreased from 41.83% to 32.00%, and the Six Sigma score (ie, Z value) increased from 1.706 to 1.967 (P < .001).
Conclusion LSS is an effective way to reduce the rate of cesarean section.
