MP66-07 IMPROVING OPERATING ROOM EFFICIENCY USING THE SIX SIGMA METHODOLOGY

Abstract

INTRODUCTION AND OBJECTIVE: Six Sigma is a technique driven by data, methodology, and a philosophy of continuous improvement to help create a system in which 99.99966% of products are free from defects. This process helps to reduce variability and waste in production, while increasing quality and decreasing cost of the final product. With this goal in mind, Six Sigma analysis was used in a rural tertiary care facility with the goal of increasing patient satisfaction, improving quality of care, and increasing efficiency of patient flow throughout the hospital. METHODS: The steps of define, measure, analyze, improve, and control (DMAIC) methodology were used. A team consisting of various operating room personnel, including anesthesiologists, surgeons, CRNAs, nurses, scrub technicians, porters and administrators was created to develop and enhance the project. Variables measured included close-to-cut time, patient-out to patient-in time (turnover time), and room utilization with goals derived from recommendations made by the Advisory Board-Surgery Compass. The workflow process was documented (Figure 1), and statistical analysis was conducted to help recognize possible shortcomings in the system, including communication and coordination errors. RESULTS: Baseline results were recorded for each surgical specialty to help determine the specific needs of each OR team. Changes in roles, such as staggered start anesthesia times, were recommended for each level of personnel based on statistical analysis and observation (Table 1). Results were followed for several years, however, ongoing construction and resistance to change has prevented further review. CONCLUSIONS: Six Sigma has been shown to be a valuable method for improving OR efficiency and reducing financial burden, however it is essential to have a proper leadership team that includes all stakeholders, horizontal and vertical leadership buy-in, active feedback, and clear goals. The synergy of these factors is key for success.Source of Funding: Administrative funds from University Medical Center, Lubbock, Texas.
