Lean Six Sigma (LSS) significantly reduced patient waiting times in a Kuwaiti hospital's obstetrics and gynaecology clinic. This process improvement initiative enhanced patient satisfaction and hospital profitability, demonstrating LSS effectiveness.
Area of Science:
- Healthcare Management
- Operations Research
- Quality Improvement
Background:
- Patient waiting times in healthcare settings are a critical factor affecting patient satisfaction and operational efficiency.
- Obstetrics and gynaecology clinics often face challenges with appointment scheduling and patient flow, leading to prolonged waiting periods.
- Implementing systematic process improvement methodologies is essential for optimizing healthcare service delivery.
Purpose of the Study:
- To apply Lean Six Sigma (LSS) methodology to decrease patient waiting times within a private hospital's obstetrics and gynaecology clinic in Kuwait.
- To identify key factors contributing to patient delays and implement targeted solutions for process optimization.
- To enhance overall patient experience and hospital financial performance through effective process management.
Main Methods:
- The Define, Measure, Analyze, Improve, Control (DMAIC) framework of Lean Six Sigma was employed.
- Data collection and analysis, including Dunnett's test, control charts, and process capability analysis, were used to assess current waiting times.
- Ishikawa diagrams and Pareto charts identified root causes such as appointment overbooking and physician punctuality issues, while Arena simulation modeled improvements.
Main Results:
- Significant reductions in patient waiting times were achieved across various patient categories, including appointment and walk-in patients on weekdays and Saturdays.
- Sigma levels improved substantially, with reductions in waiting time ranging from 46% to 67% for different patient groups.
- A cost-benefit analysis projected substantial savings, estimating a total of $5,820,319 by 2025, with a present project value of $656,459.
Conclusions:
- Lean Six Sigma is an effective tool for process improvement in healthcare, specifically for reducing patient waiting times in specialized clinics.
- The study highlights the positive impact of LSS on patient satisfaction and hospital profitability.
- The findings provide a scalable model for other healthcare facilities seeking to optimize operational efficiency and patient care quality.
