A tertiary care hospital recently experienced a near-miss event where a patient almost received a lethal dose of concentrated potassium chloride due to an automated dispensing cabinet (ADC) stocking error. In response, the hospital administration decides to proactively evaluate the new ADC system workflow being implemented in the intensive care unit before it goes live. The quality improvement committee initiates a Failure Mode and Effects Analysis (FMEA). Arrange the following steps of the FMEA process in the correct chronological sequence.
- 1Convene a multidisciplinary team of stakeholders including frontline ICU nurses and pharmacists.
- 2Develop a detailed process map of the intended automated dispensing cabinet workflow.
- 3Brainstorm potential failure modes and vulnerabilities at each discrete step of the process map.
- 4Calculate a Risk Priority Number for each failure mode based on severity, frequency, and detectability.
- 5Design and implement targeted interventions for the vulnerabilities with the highest risk scores.
Cevap
The correct chronological sequence for a Failure Mode and Effects Analysis is: 1) Convene a multidisciplinary team, 2) Develop a detailed process map, 3) Brainstorm potential failure modes, 4) Calculate a Risk Priority Number, 5) Design and implement targeted interventions.
Failure Mode and Effects Analysis (FMEA) is a proactive, prospective quality improvement methodology designed to identify and eliminate potential system failures before they result in patient harm. The standardized FMEA sequence begins with assembling a multidisciplinary team of frontline subject matter experts (e.g., nurses, pharmacists, physicians). Next, this team must thoroughly map or diagram the intended process to establish a shared understanding of its sequence. Once the process is mapped, the team brainstorms potential failure modes (what could go wrong) at each discrete step. To determine which failures are most critical, the team then calculates a Risk Priority Number (RPN) for each vulnerability by multiplying its severity, probability of occurrence, and likelihood of being detected. Finally, the highest RPNs dictate which steps require immediate targeted interventions and system redesign prior to implementation.
