In response to demands on healthcare, systems have looked to refine current processes to use time, materials, and finances more efficiently. Lean/Six Sigma (L/SS) is a model that has been used to improve procedural efficiency in various settings. The purpose of this study was to implement L/SS into an outpatient private practice setting and to evaluate the effect on efficiency as measured in the length of individual patient visits who presented to that clinic for routine re-evaluation. In this study, the amount of time between a patient’s entrance and exit from the clinic was documented for 878 patients before implementation of L/SS and for 319 patients after an 18 month implementation period. Statistical analysis of the variance was completed using ANOVA and found to have both a statistically significant (P <.05) and clinically significant change (eight minutes) in visit time between the two groups.
