An ambulatory surgery center has noted a steady increase in same-day procedure cancellations over the past six months, primarily due to incomplete preoperative medical clearances. The medical director convenes a multidisciplinary quality improvement team to address this issue using the Lean Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) framework. Arrange the following actions in the correct chronological sequence according to this methodology.
- 1Draft a formal problem statement detailing the current 12% cancellation rate and establishing a target goal of 4% within six months.
- 2Extract data from the electronic health record to map the current preoperative workflow and quantify the exact frequencies of specific cancellation reasons.
- 3Construct an Ishikawa (fishbone) diagram with front-line staff to uncover the root causes leading to missing preoperative documentation.
- 4Pilot a mandatory nursing pre-admission phone call 72 hours prior to the scheduled procedure to verify clearance status.
- 5Create a monthly automated dashboard to track ongoing cancellation metrics and ensure sustained compliance with the new workflow.
Answer
The correct sequence follows the DMAIC framework: Define the problem, Measure baseline data, Analyze root causes, Improve the process, and Control to sustain gains.
The DMAIC methodology is a core component of Lean Six Sigma used for process improvement. It must follow a strict, sequential order: Define (establish the problem and goals), Measure (collect baseline performance data), Analyze (identify root causes using tools like Ishikawa diagrams), Improve (implement and pilot solutions), and Control (monitor metrics to sustain the gains).
