Hospitals across the United States are beginning to embrace lean and Six Sigma business management strategies in attempts to reduce costs and improve productivity, according to a new national benchmarking study by the American Society for Quality. The ASQ Hospital Study, to which 77 hospitals responded, is the first study to investigate the implementation of lean and Six Sigma in U.S. hospitals.
While applied in manufacturing extensively – and applicable to all industries – these management methods have moved into healthcare recently, but with little substantive data available for hospitals to assess the worth of the methods. Lean emphasizes removing waste from organizations and processes while focusing on and delivering more value to customers. Six Sigma focuses on variation reduction in processes, products and services.
According to the ASQ study, 53 percent of hospitals report some level ("minor," "moderate" or "full") of lean deployment, and 42 percent of hospitals report some level of Six Sigma deployment. Few hospitals participating in the study report "full deployment" of either lean (4 percent of hospitals) or Six Sigma (8 percent). The reasons that neither method has been deployed in hospitals include: the need for resources (59 percent of hospitals), lack of information (41 percent), and leadership buy-in (30 percent). Eleven percent of hospitals surveyed were not familiar with either method.
"During these turbulent economic times when healthcare costs continue to rise, it is crucial that U.S. hospitals look to methods like lean and Six Sigma to become more efficient, said Dr. James Levett, chair of ASQ’s Healthcare Division and chief medical officer for the Physicians’ Clinic of Iowa. "This study indicates that many healthcare systems are still in the ‘infancy stage’ when it comes to using these vital cost-cutting tools."
Reasons hospitals use lean and/or Six Sigma
Primary factors that hospitals deploy lean and/or Six Sigma are:
Hospitals report the biggest challenges in implementing lean or Six Sigma include sustaining improvements, competition from other initiatives, leadership commitment and availability of resources. Hospitals surveyed report a median investment of $25,000 for their 2007 lean initiatives and a median investment of $96,485 for their 2007 Six Sigma initiatives.
Top areas for lean and/or Six Sigma, and success of efforts
Hospitals were asked to identify the departments where lean and/or Six Sigma have been deployed, as well as the general rate of success for those efforts. While the data returned is for a small sample of hospitals that have actually deployed Six Sigma and lean (and, thus, statistically has a wide margin of error), it nonetheless provides a starting benchmark for the industry for location of efforts and potential for returns.
The locations most likely to have lean and/or Six Sigma in place are:
Ancillary/support services deployment
Hospitals deploying in the following areas report the following success rates:
Clinical success ("somewhat" or "highly" successful)
Ancillary/support services success ("somewhat" or "highly" successful)
Non-clinical/support success ("somewhat" or "highly" successful)
