Improving Throughput, Teamwork, Productivity, and Patient Experience Using Lean Six Sigma Methodology

Nova Southeastern University, Davie, Florida, USA

Objective: The purpose of this study is to share the outcomes and benefits of using Lean Six Sigma methodology to improve efficiency and cost effectiveness of the ICU workflow processes that increases staff engagement, productivity, teamwork and patient experience. Background: Lean and Six Sigma (LSS) methodologies were developed in the manufacturing industry to increase efficiency and eliminating waste. The method is aimed at seamlessly linking processes for time and cost saving while maintaining high quality. The Six Sigma five-step methodology is data driven. The LSS methodologies were implemented in the ICU to improve efficiency with throughput and productivity. The goal was to improve workflow and decrease the ready to move (RTM) time by 50%. Methods: Pilot and implementation ran for 38 days using a multidisciplinary team approach. A Charge Nurse/ Physician Rounding Tool was developed and was used during rounding at 4pm, 10pm and 6am. Patients were identified for transfer and transfer orders were obtained. A Patient Transfer Checklist was created for nurses to anticipate, communication, and utilize the checklist to prepare the patient for timely transfer. Results: Results showed sufficient evidence at the alpha level of 0.05 indicating that the average Order to RTM Time is statistically significantly different compared to baseline. The RTM was decreased to 28 minutes generating a cost savings of $89,107. Conclusion: Using the LSS method was an effective approach to increase cost savings, bed capacity, and productivity and decrease length of stay. Additional benefits included improved patient satisfaction, staff engagement, work standardization and efficiency.
