DMAIC in improving patient care processes: evaluation based on a systematic review from the perspective of Lean Six Sigma in healthcare

DMAIC is a Six Sigma methodological framework that has attracted the attention of researchers in the field of health (REIS et al., 2021). It is noticed that DMAIC has been used in several processes in health services, such as dispensing medication, hospital discharge and patient admission. Lean Six Sigma, based on the association of DMAIC with lean, brought important and valuable results in the context of health care, such as reducing the length of stay (LOS) in services, increasing patient satisfaction and reducing employee satisfaction. This study aims to evaluate how Lean Six Sigma/DMAIC has been implemented in the health area and its impacts on patient health care processes.
