TL;DR: This is the first known application of Lean Six Sigma to office-based USFNA in the evaluation of head and neck lesions and shows how ultrasound reduces time to diagnosis, costs, patient inconvenience and travel, exposure to ionizing radiation, intravenous contrast, and laboratory tests.
Abstract: Objectives(1) Confirm the positive value stream of office-based ultrasound using Lean Six Sigma; (2) demonstrate how ultrasound reduces time to diagnosis, costs, patient inconvenience and travel, e...

TL;DR: In this paper, a shimming process for a mechanically-driven screw press, whereby compressor airfoils (blades) are produced for a gas turbine, is examined, and the five-phase approach to problem solving used in Six Sigma projects is applied.
Abstract: When the objective of the manufacturer is to eliminate waste or create a more efficient process, innovative techniques are often sought for process improvement. The statistical tools used by Six Sigma practitioners are specifically designed for this purpose; they are frequently used to address problems across a wide number of production systems. Each manufacturing application, however, brings a unique array of potential causes and effects that must be considered to properly model process behaviour. This paper specifically examines a shimming process for a mechanically-driven screw press, whereby compressor airfoils (blades) are produced for a gas turbine. To enhance product quality and identify improvements in process performance, the five-phase approach to problem solving used in Six Sigma projects is applied. As a result of the changes implemented in this case study, the product defect level is reduced by as much as 94% and the Six Sigma rating is increased from 0.868 to 3.207.

TL;DR: This project demonstrates that the LSS methodology can be applied successfully to the health care setting to make sustainable process improvements if used correctly and completely.
Abstract: Lean Six Sigma (LSS) is a process improvement methodology developed in the manufacturing industry to increase process efficiency while maintaining product quality. The efficacy of LSS application to the health care setting has not been adequately studied. This article presents a quality improvement project at the U.S. Naval Academy that uses LSS to improve the mass immunizations process for Midshipmen during in-processing. The process was standardized to give all vaccinations at one station instead of giving a different vaccination at each station. After project implementation, the average immunizations lead time decreased by 79% and staffing decreased by 10%. The process was shown to be in control with a capability index of 1.18 and performance index of 1.10, resulting in a defect rate of 0.04%. This project demonstrates that the LSS methodology can be applied successfully to the health care setting to make sustainable process improvements if used correctly and completely.

TL;DR: Lean Six Sigma tools used in this study were cause-and-effect diagrams, spaghetti diagrams, five-why analysis, project charters, brainstorming, control charts, and hypothesis testing.
Abstract: Hospital medication errors are costly and contribute to patient mortality, morbidity, and decreased health care quality. Errors result from poor systems design more commonly than from healthcare st...
