Clinical Patient Safety
Frameworks
Safety is a system property, not an individual trait. High-reliability organizations (HROs) emphasize preoccupation with failure, reluctance to simplify, sensitivity to operations, commitment to resilience, and deference to expertise. Just culture distinguishes human error (console), at-risk behavior (coach), and reckless behavior (discipline). Human-factors concepts-slips, lapses, mistakes, and the Swiss-cheese model-explain how layered defenses fail together.
Tools
- RCA: reactive, conducted after a sentinel event; asks what happened, why, and which systems failed.
- FMEA: proactive, performed before a process change; scores failure modes by severity, occurrence, and detectability.
- CUSP and TeamSTEPPS: culture and teamwork interventions (SBAR, checklists, huddles, speak-up skills).
- Trigger tools and harm indices: surveillance to detect adverse events that reporting misses.
Sentinel events and disclosure
A sentinel event is an unexpected occurrence involving death or serious physical or psychological injury, or the risk thereof; a root cause analysis is expected. Never events (wrong-site surgery, retained foreign object) are largely preventable. Disclosure to patients should be prompt, factual, empathetic, and coordinated with risk management and counsel; apology protections vary by state.
Traps
Conflating RCA with FMEA is the classic distractor. Questions also imply blaming an individual for a system failure, or assume disclosure increases liability (evidence generally shows the opposite). For “first action” items, the answer is usually stabilize the patient and ensure safety, then report.
Rule of thumb
Near misses are free lessons-investigate them with the same rigor as harm events at a fraction of the cost.
