Difficulty: MediumQuality Improvement Models and Methodologies

A large psychiatric hospital is preparing to implement a new continuous vital sign monitoring wearable device for patients receiving rapid tranquilization for acute agitation. The hospital's risk management committee wants to identify and mitigate potential vulnerabilities in how nursing staff will respond to the device's alarms before the devices are deployed on the clinical units. A multidisciplinary team is assembled to map the anticipated workflow and brainstorm how the alarm response process might fail. The team then scores each potential failure based on its clinical severity, probability of occurrence, and likelihood of detection. Safeguards are subsequently designed to address the highest-scoring vulnerabilities. Which of the following best describes the methodology the team is utilizing?

  2. B
    Root Cause Analysis
  3. C
    Plan-Do-Study-Act cycle
  4. D
    Lean Six Sigma
  5. E
    Pareto analysis

Answer

Failure Mode and Effects Analysis
The correct answer is Failure Mode and Effects Analysis (FMEA). FMEA is a proactive, prospective quality improvement methodology used to systematically evaluate a process to identify where and how it might fail, and to assess the relative impact of different failures before they reach the patient. The defining characteristics of FMEA described in the scenario include occurring prior to system implementation and scoring potential failures based on severity, probability of occurrence, and likelihood of detection (which are multiplied together to calculate a Risk Priority Number, or RPN). Interventions are then targeted at the steps with the highest RPNs.

Step-by-Step Solution

1
Analyze the timing and goal of the quality improvement intervention described in the scenario.
The intervention is taking place 'before the devices are deployed' to preemptively identify vulnerabilities, indicating a prospective, proactive approach.
Determining whether the analysis is prospective (before an event) or retrospective (after an event) is the critical first step in identifying the correct QI methodology.
2
Evaluate the specific activities and calculations performed by the multidisciplinary team.
The team maps the anticipated workflow, brainstorms potential failures, and scores them based on severity, probability of occurrence, and likelihood of detection.
These specific components (identifying failure modes and calculating a risk score based on severity, occurrence, and detection) are the defining features of a specific analytical tool.
3
Match the identified characteristics with the appropriate quality improvement framework.
A prospective analysis that anticipates failures and scores them using these three specific variables is characteristic of Failure Mode and Effects Analysis (FMEA).
FMEA is uniquely designed for prospective hazard analysis and utilizes these exact scoring metrics to generate a Risk Priority Number for each potential failure.

Key Concept

Failure Mode and Effects Analysis (FMEA) is a prospective, proactive quality improvement tool used to identify, score, and mitigate potential system failures before a new process is implemented or an adverse event occurs.
