The author conducted full process analysis of red bag waste management including the human factor, economic, environmental, assessments of entire process by implementing Lean Six Sigma approach. However numbers of papers have applied Lean Six Sigma method to improve quality factors in healthcare, no single publication has considered all areas that are covered in this study. The data illustrates proper disposal can minimise waste by 55% which would lead to a reduction of environmental impact and a cost savings for the healthcare facility.
