Sunday papers often make for light reading, but an article I stumbled upon on, compelled me to think deeply. Titled “Don’t Let a Hospital Make You Sick,” the piece was brimming with startling facts about healthcare practices that are unfortunately more common than most people realize.

The Unsettling Reality of Healthcare Errors

The article unearthed troubling statistics such as 1,300 instances per year of operations conducted on the wrong patient or removal of the wrong organ or limb. Furthermore, an astounding 98,000 deaths annually could be attributed to medical mistakes. Perhaps most shocking was the frequency of surgical instruments being left inside patients – once every 5,000 procedures.

A Comparative Look: Six Sigma and Current Healthcare Practices

From the perspective of Six Sigma, a set of techniques and tools designed for process improvement, these processes are substantially below par. The tolerance for error in Six Sigma is remarkably low, equating to 3.4 defects per million opportunities. In comparison, these medical errors indicate a system performing far below the desired Six Sigma levels. The question arises – why do we tolerate such abysmal quality from an institution as crucial as healthcare?

A New Approach: Integrating Six Sigma and Lean Manufacturing in Healthcare

Having spent significant time working within healthcare, I can confidently assert that there’s no reason why our healthcare system can’t be delivered at a quality level comparable, if not superior, to that of a beer can. It’s time for a paradigm shift – and Six Sigma, combined with Lean Manufacturing principles, could be our ticket to drastic improvement.

The Six Sigma Way: Reducing Errors and Enhancing Quality

Six Sigma methodologies focus on identifying and eliminating variability in processes, reducing errors, and enhancing overall quality. In a healthcare setting, this could translate to improved patient outcomes, lower rates of preventable mistakes, and an increase in overall patient satisfaction.

Lean Manufacturing: Streamlining Healthcare Processes

On the other hand, Lean Manufacturing principles emphasize eliminating waste, improving process flow, and delivering value to customers. Applied to healthcare, these principles can help minimize unnecessary procedures, streamline patient care processes, and ultimately deliver higher quality, more efficient care.

The Road Ahead: Championing Quality in Healthcare

The integration of Six Sigma and Lean Manufacturing in healthcare holds tremendous potential. Championing these quality improvement methods will not only revolutionize healthcare processes but, more importantly, will protect patients from preventable errors. It’s high time we demanded a level of quality from our healthcare providers that matches their significance in our lives.


There’s an urgent need for a shift in perspective – one that understands the immense value of Six Sigma and Lean Manufacturing principles in healthcare. By embracing these methodologies, we can work towards a future where preventable errors are a rarity, not a norm, and where each patient can trust in the quality and safety of their care.
