As an ancillary provider, laboratory represents only 5% of the healthcare dollar, but laboratory results impact 70% of the diagnostic process. Recently, the Institute of Medicine released a highly publicized study on the high rate of medical errors caused by healthcare providers in the United States . The study, titled "To Error is Human", details medical errors that cause 50,000 to 100,000 preventable deaths each year. Those are sobering statistics and this landmark study has resulted in considerable debate in healthcare circles as to what to do about it.

For Laboratory Sciences of Arizona and Sonora Quest Laboratories, Quality is one of our core Values, and there is no debate. Our decision is to proactively take the challenge to reduce laboratory errors by endeavoring to attain Six-Sigma...99.9997% accuracy or 3.4 ppm errors. The pursuit and attainment of Six-Sigma quality is not a quick fix...it's a major challenge, particularly, since no medical institution or laboratory has ever attained this level of quality. But this is a unique opportunity to improve the quality of healthcare we provide to our patients and clients, reduce the cost of poor quality, and distinguish Laboratory Sciences of Arizona and Sonora Quest Laboratories as the preeminent leader for laboratory medicine in Arizona. Simply put, our goal is to become the quality benchmark for laboratories in Arizona, and I am confident our 2000 plus dedicated employees are committed to providing the level of outstanding quality and service to our patients and clients that will make this goal a reality.

What is Six Sigma Quality?

Right from the beginning, quality has been our core focus at Sonora Quest Laboratories. Six Sigma is our breakthrough process improvement strategy, by which we plan to achieve a new quality standard for the health care industry.

Six Sigma did not begin at Sonora Quest Laboratories. It had its birth in 1979 at Motorola. Six Sigma is focused on preventing problems by building quality into processes - by not having problems in the first place. The Six Sigma method utilizes full-time dedicated Black Belts (project managers) who receive a month of formal classroom training in process analysis and statistical methods as well as mentoring by Six Sigma experts.

Six Sigma stands for 3.4 defects per one million opportunities.

  • 3 Sigma 66,800 defects per one million opportunities
  • 4 Sigma 6,210 defects per one million opportunities
  • 5 Sigma 233 defects per one million opportunities
  • 6 Sigma 3.4 defects per one million opportunities
Good companies are 3-4 Sigma, but good is not good enough in healthcare. We believe that the healthcare industry must strive for perfection. At Sonora Quest Laboratories, we are dedicated to providing the highest quality to the patients whose specimens are entrusted to us.

How Six Sigma Works

The Six Sigma method starts by asking the fundamental question: What is critical to our customers? Then rigorous analysis is applied to all processes in the business to assess whether they are delivering what customers require. Each time processes don't deliver, that is a defect. Six Sigma is passionate about using data to uncover the root causes of those defects and eliminating them from our processes. The ultimate objective is to deliver to customers what is critical to them each and every time - to produce "virtual perfection" from the customer's perspective. Common sense and force of personality are not means to reach dramatic improvements. The only way is to ask the tough questions and to use rigorous statistical and financial analysis. When problems are reduced, costs decline and customer satisfaction improves.

Why We Are Doing It: The Moral Imperative

According to the Institute of Medicine 's study, medical mistakes kill between 44,000-98,000 hospitalized Americans a year. That is more people than are killed in automobile incidents per year. Yet, while other industries (primarily manufacturing industries) have adopted Six Sigma processes to improve performance, healthcare has lagged behind… Until now!

SG Cowen Securities, a leading market analyst with a focus on healthcare, has determined that 70% of health care spending is impacted by clinical test results. Sonora Quest Laboratories provides critical input to healthcare decisions for more than 5 million patients each year in Arizona . Quite simply, we have a moral and ethical responsibility to our customers and patients to deliver unparalleled quality and excellence in clinical testing.

The Business Imperative

Six Sigma is good business. We believe it will provide the foundation and fuel to attract and retain the best employees and help us to exceed our customers' expectations. As companies like Motorola, Allied Signal and Texas Instruments have already found, Six Sigma delivers business results that can accelerate growth, reduce costs and ultimately deliver extraordinary profits to our stakeholders.

Our Progress to Date

In 2000, leaders throughout our organization were pulled out of their operating positions to become Black Belts or full-time, Six Sigma project leaders. Our Black Belts lead high-impact project teams focused on improving performance in areas of our business that are critical to customers. Each of these Black Belts has received four intensive weeks of training to learn the Six Sigma approach and how to lead teams through the process. The training is dedicated to a disciplined, rigorous and data-based process improvement strategy. It has proven to achieve dramatic results.

The senior leadership team of Sonora Quest Laboratories is driving the major investment and commitment to dramatically improve our quality. Projects have been initiated in a variety of process areas: patient service centers, specimen processing, and the analytical laboratory. These projects are achieving dramatic defect reductions (50-90% defect rate reductions) in a variety of areas and proven solutions are being deployed throughout our organization.
