What is Six Sigma in Healthcare? 

Six Sigma, a methodology initially developed in the manufacturing industry, has also found wide-ranging applications in the Healthcare sector. The systematic approach of Six Sigma focuses on improving care quality, patient safety, and operational efficiency within Healthcare organisations.  

In the context of Healthcare, Six Sigma recognises that small, incremental improvements across various processes can have a substantial impact on patient care and organisational performance.  

Further more, using data-driven decision-making and process improvement techniques, Six Sigma offers a powerful framework to address challenges and enhance healthcare outcomes. The key principles of Six Sigma in Healthcare include the following:  

a) Customer focus: Six Sigma in Healthcare emphasises the importance of meeting and understanding the needs of patients and other stakeholders involved in the process.

b) Data-driven decision-making: Six Sigma also relies on robust data collection and analysis to drive decision-making. Statistical tools and techniques are used to identify areas of improvement, measure performance, and monitor progress.

c) Process improvement: It also identifies and analyses key processes in Healthcare organisations. Therefore, it aims to streamline them, reduce variations, and eliminate errors. This further leads to enhanced efficiency, reduced costs, and improved patient outcomes.

d) Teamwork and collaboration: Six Sigma encourages multidisciplinary collaboration. It brings Healthcare professionals, administrators, and other stakeholders together to achieve common goals.


 

Five steps for quality improvement in Six Sigma

The Six Sigma approach can translate to measurable quality improvement, if organisations follow these five key steps, described as follows:

a) Define: The first step involves acquiring the clarity on who the patients are, and what they require. The capabilities of the process being measured also come into the picture, followed by the organisation’s objectives.

b) Measure: The second step entails the organisation’s vision of what its improvement journey will look like, and an analysis of what data will their efforts be focussed on and measured. The metrics used to define their performance in the Healthcare industry include their service level, patient satisfaction, service cost, and clinical excellence.

c) Analyse: The third step comprises of data collection and analysis using the necessary tools.

d) Improve: The fourth step involves the implementation of modifications to enhance the process.

e) Control: The fifth step is where the organisation monitors its performance to maintain their improvement.

The Affects of Six Sigma in Healthcare

Organisations have successfully adopted the Six Sigma methodology as a part of their efforts in quality improvement. Six Sigma approaches and tools have had a positive impact on the Healthcare industry. Here are the various examples of how Six Sigma has positively affected organisations in Healthcare:

1) Boston Medical Centre: The centre observed significant improvements through their focus on diagnostic imaging, which helped bring cost savings and an increase in revenue of over £1.7 million.

2) The Women and Infants Hospital of Rhode Island: Six Sigma was successfully implemented by this hospital for standardising its embryo transfer procedures. The standardisation resulted in an increase of its implementation rates by 35 percent.

3) Rapides Regional Medical Centre: The Rapides Regional Medical Centre reduced the defects in its emergency department by utilising the Six Sigma methodology. The implementation of the methodology resulted in a decline in wait times, increased patient numbers, and an annual savings of over £740,000 for the hospital.
