A large tertiary care center is preparing to integrate a novel, automated continuous insulin infusion algorithm into the electronic health record (EHR) for the medical intensive care unit. Because intravenous insulin administration is highly prone to errors, the patient safety committee decides to proactively evaluate this system prior to its deployment. They initiate a Failure Mode and Effects Analysis (FMEA). Arrange the following procedural steps of the FMEA in the correct chronological sequence.
- 1Assemble a multidisciplinary task force consisting of endocrinologists, intensivists, nursing staff, and clinical informaticists.
- 2Construct a detailed graphical representation of the proposed insulin ordering and administration workflow.
- 3Systematically identify potential defects or breakdown points at each step of the newly modeled workflow.
- 4Quantify the severity, occurrence probability, and detectability of each identified defect to establish priority scores.
- 5Formulate and integrate high-reliability systems changes targeting the vulnerabilities with the highest priority scores.
- 6Estimate the residual risk by recalculating priority scores assuming the successful implementation of the proposed systems changes.
Answer
The correct chronological sequence for a Failure Mode and Effects Analysis (FMEA) is: 1) Assemble a multidisciplinary task force, 2) Construct a detailed graphical representation of the workflow, 3) Systematically identify potential defects, 4) Quantify risk via priority scores, 5) Formulate systems changes, and 6) Estimate residual risk.
Failure Mode and Effects Analysis (FMEA) is a highly structured, prospective tool used to evaluate complex processes before they go live. The sequence begins with defining the team. Once formed, the team maps the exact process (process mapping). Only after the steps are explicitly defined can the team brainstorm potential failure modes at each step. These modes are then objectively quantified using a Risk Priority Number (RPN)—calculated by multiplying severity, probability of occurrence, and likelihood of detection. High-RPN items are addressed with targeted interventions (e.g., forcing functions). Finally, the team must recalculate the expected RPN to ensure the residual risk is acceptable prior to full implementation.
Step-by-Step Solution
Key Concept
Failure Mode and Effects Analysis (FMEA) is a prospective, proactive quality improvement process used to identify and mitigate potential systems failures before a new workflow or technology is implemented.
