Might industrial processes improve quality, reduce waiting times, and enhance the working environment?
Radical thinking about the design of industrial processes over the last century has greatly improved the quality and efficiency of manufacturing and services. Similar methods to deliver higher quality health care at lower cost would be extremely valuable. In health care, however, we must also consider how patients feel about the processes and the extent to which they are able to exercise meaningful, informed choice.
Although the potential of using industrial methods in health care has been discussed,1 2 their value is hotly debated. Some doubt that there is a valid analogue between industry and health care, while others see it as an excuse to force an overworked community to work even harder.3 4 We describe three established industrial approaches—lean thinking,5 6 theory of constraints,7 and six sigma,8 9—and explore how the concepts underlying each might relate to health care.
Lean health care
Lean thinking started with Toyota in the 1950s and was developed by Womack and Jones.6 It seeks to provide what the customer wants, quickly, efficiently, and with little waste (box 1). An obvious application to health care lies in minimising or eliminating (within a framework of clinical excellence) delay, repeated encounters, errors, and inappropriate procedures. Some conceptual issues that arise in relating lean thinking to health care include the extent to which patients, service providers, or even taxpayers equate to customers in the commercial setting and the way in which health outcomes, patient satisfaction, or even cost can be legitimately used to define value. Furthermore, although the routes followed by items in a manufacturing process are clearly defined, those followed by individual patients depend on clinical judgments at various stages, which may complicate a rigorous analysis.
