Since the discovery of X-rays in 1895, the field of diagnostic imaging has undergone dramatic changes. Within a year after its introduction, the application of X-rays to diagnosis and therapy had already become an established part of medicine. The decades to follow produced a steadily increasing stream of innovation – including the advent of nuclear […]

Software can be a helpful tool but it is not a magic wand. After investing half a million dollars in tracking software for its call center and still seeing a high volume of complaints, one company used DMAIC to turn a disaster into a success.

The diagnostic testing center at Northwestern Memorial Hospital in Chicago is an outpatient laboratory that is kept perennially busy serving the needs of the community. Thousands of walk-in patients are seen each year, primarily for blood tests (phlebotomy) and electrocardiograms (EKGs). Although Northwestern receives acclaim for its patient care, some complaints had begun to surface […]

A power distribution company in India, serving domestic, commercial, industrial and agricultural users, was not meeting the country’s performance standard regulations for metering and billing. A Six Sigma project was initiated to reduce cycle time.

The Emergency Department (ED) increasingly is becoming the sole source of medical care for many individuals. It also is often called the “gateway” to the hospital since it is the first encounter many patients have with the hospital. Thus it is the place where positive or negative perceptions of the hospital initially may be formed. […]

Design of experiments (DOE) is a useful tool for determining specific factors affecting defect levels in a product. A major automotive company learned just how valuable this tool is when it conducted a study of defects occurring in its alternator product. DOE was applied to identify the cause of ventilation noise within the alternator, a […]

A DMAIC project at New York-Presbyterian Hospital improved throughput – case start time, room turnaround time and patient prep time – in three cardiac cath labs.

Liquid Controls, a manufacturer of high-quality flow meters and accessories for accurate liquid measurement, is a well-practiced user of Six Sigma methodologies. Having adopted Six Sigma in 1999 and made significant strides in improving manufacturing processes, the company more recently began to turn attention to transactional processes for serving customers. Liquid Controls identified several processes […]

The managers of a lockbox operation in the upper Midwest were not at all pleased. The corporate clients for whom they processed millions of dollars in payments were very intolerant of errors. Yet in the first months of a new quality improvement effort, the error rate per 100,000 transactions doubled from 15 to 30. Truth […]

Healthcare organizations currently implementing Six Sigma are finding no shortage of opportunities for applying this approach – and many are reaping substantial benefits in terms of cost, quality and productivity. One area increasingly targeted in recent years has been the cardiac catheterization lab, which is generally a high-volume, challenging and complex environment within any healthcare facility. […]

The fact that patients are not entirely safe in a hospital is not breaking news. Errors in healthcare delivery were occurring long before the 1999 report by the Institute of Medicine exposed significant gaps in the healthcare system in the United States. The institute’s report, To Err Is Human: Building a Safer Health System, found […]
