Generate comprehensive root cause analysis (RCA) drafts for adverse events and sentinel events using the VA National Center for Patient Safety RCA methodology, including causal factor charting, five whys analysis, and corrective action development. Use when conducting RCAs for sentinel events, serious safety events, near misses with high potential for harm, or recurring incident patterns requiring systematic investigation.
Generate structured root cause analysis (RCA) drafts following the VA National Center for Patient Safety (NCPS) model — the most widely adopted RCA methodology in US healthcare. This skill guides the systematic investigation of adverse events from event timeline reconstruction through causal factor identification to strong corrective action development. Joint Commission requires RCA completion within 45 business days of a sentinel event, and this skill accelerates the process by structuring the analysis, ensuring all required elements are addressed, and generating corrective actions that meet the Joint Commission's criteria for acceptability.
| Input | Description | Format |
|---|---|---|
event_summary | Detailed event description including timeline, participants, and outcome | Text narrative |
patient_record | Relevant medical record entries surrounding the event (de-identified) | Clinical documentation |
interviews | Staff interview notes from involved individuals and witnesses | Text summaries |
policies_procedures | Applicable organizational policies, protocols, and guidelines | Document references |
equipment_info | Device or equipment data relevant to the event | Structured object |
environmental_data | Staffing levels, census, physical environment conditions at time of event | Structured object |
prior_events | Previous similar events and prior corrective actions | Array of records |
Construct a detailed chronological timeline and identify causal factors:
Timeline Construction:
Causal Factor Identification:
Apply the Five Whys technique iteratively to each causal factor:
Five Whys Process:
Stop when you reach a factor that is:
Ishikawa (Fishbone) Categories for Healthcare:
| Category | Focus Areas |
|---|---|
| Human factors | Knowledge, skills, fatigue, distraction, workload, teamwork |
| Communication | Handoffs, orders, documentation, terminology, hierarchy |
| Equipment/technology | Design, maintenance, availability, user interface, alarms |
| Environment | Staffing, workspace, noise, lighting, interruptions |
| Policies/procedures | Adequacy, clarity, currency, accessibility, enforcement |
| Patient factors | Acuity, complexity, language, behavior, preferences |
| Organizational/management | Culture, resources, priorities, training investment, oversight |
Apply the VA National Center for Patient Safety triage framework to validate root causes:
For each identified root cause, answer:
Was the task that had to be performed clearly communicated?
Was there a clearly defined process/procedure for the task?
Were the right people assigned to the task?
Was the environment conducive to safe task performance?
Were there adequate barriers/safeguards in place?
Validate identified root causes against acceptance criteria:
A valid root cause must be:
Root Cause Quality Test:
Develop strong corrective actions for each root cause:
Action Strength Hierarchy (strongest to weakest):
| Strength | Action Type | Examples | Sustainability |
|---|---|---|---|
| Strong | Architectural/physical change | Forcing functions, equipment redesign, eliminating look-alike packaging | High — does not depend on human behavior |
| Strong | Standardize/simplify | Checklists, standard order sets, simplified processes | High — reduces complexity |
| Strong | Tangible involvement of leadership | Executive safety rounds, resource allocation decisions | High — signals organizational priority |
| Intermediate | Increase staffing/redesign workflow | Dedicated safety personnel, workload redistribution | Moderate — requires sustained investment |
| Intermediate | Software/technology enhancement | CDS alerts, barcode scanning, smart pumps | Moderate — requires maintenance |
| Intermediate | Redundancy/independent checks | Double-check processes, read-back verification | Moderate — requires compliance |
| Weak | Education/training | In-service training, competency validation | Low — knowledge decays without reinforcement |
| Weak | New policy/procedure | Written policy without enforcement mechanism | Low — awareness and adherence decline |
| Weak | Increased awareness/vigilance | Posters, reminders, "be more careful" | Very Low — unsustainable |
