A hospital network has recently expanded its Quality and Safety Department to standardize the approach to medical errors and process improvements. The new director is conducting a workshop for department chairs on the appropriate utilization of various quality improvement and patient safety frameworks. Match each clinical safety scenario or definition with the most appropriate patient safety methodology.
- Root Cause Analysis (RCA)A retrospective, systematic investigation of the contributing systemic factors that led to an unintended surgical site infection.
- Failure Mode and Effects Analysis (FMEA)A proactive, forward-looking evaluation of a newly designed medication delivery pathway to identify and mitigate potential vulnerabilities prior to launch.
- Plan-Do-Study-Act (PDSA) cycleAn iterative, small-scale test of a new discharge checklist on one internal medicine floor, with the goal of rapid refinement based on observed outcomes.
- Control ChartA time-series graphical display with statistically determined upper and lower limits, used to assess whether a hospital's monthly readmission rate remains within a predictable range.
Cevap
Root Cause Analysis matches the retrospective investigation of an adverse event; Failure Mode and Effects Analysis matches the proactive evaluation of a new pathway; the Plan-Do-Study-Act cycle matches the iterative, small-scale test of a checklist; and the Control Chart matches the time-series graphical display with statistical limits.
Each quality improvement methodology serves a distinct role: RCA is used to retrospectively investigate incidents that have already occurred, FMEA is used to prospectively assess new processes before they cause harm, the PDSA cycle is an iterative framework for real-world implementation, and a Control Chart is a statistical tracking tool to monitor process stability.
