Methodology

Step 1: Event and Causal Factor Charting

Construct a detailed chronological timeline and identify causal factors:

Timeline Construction:

• Map every relevant event on a time-sequenced chart
• Begin with the earliest contributing event and end with the adverse outcome and discovery
• Include parallel tracks for different participants (patient, nurse, physician, pharmacy, etc.)
• Mark each decision point where an alternative action could have changed the outcome
• Identify handoff points and transitions of care
• Note time gaps or delays that may have contributed

Causal Factor Identification:

• At each timeline node, identify conditions that allowed the event to progress
• Distinguish between:
  • Active causes: Proximate actions or inactions by individuals
  • Latent causes: Systemic conditions that enabled the active causes
  • Contributing conditions: Factors that increased likelihood but did not directly cause the event

Step 2: Root Cause Identification (Five Whys + Ishikawa)

Apply the Five Whys technique iteratively to each causal factor:

Five Whys Process:

1. Why did this happen? → Identify immediate cause
2. Why did that occur? → Identify underlying process failure
3. Why does that process fail? → Identify systemic gap
4. Why does that gap exist? → Identify organizational factor
5. Why hasn't it been addressed? → Identify root cause (management system, culture, resource allocation)

Stop when you reach a factor that is:

• Under organizational control (can be changed)
• Systemic (not dependent on individual performance)
• Actionable (a feasible intervention can address it)

Step 3: VA NCPS Triage Questions

Apply the VA National Center for Patient Safety triage framework to validate root causes:

For each identified root cause, answer:

1. Was the task that had to be performed clearly communicated?

   • Were there ambiguities in the task assignment or instructions?
   • Was relevant information available to the person performing the task?

2. Was there a clearly defined process/procedure for the task?

   • Did a policy or protocol exist?
   • Was it current, evidence-based, and accessible?
   • Was it known to the staff involved?

3. Were the right people assigned to the task?

   • Appropriate credentials, competencies, and experience?
   • Adequate staffing levels for the workload?
   • Appropriate supervision available?

4. Was the environment conducive to safe task performance?

   • Physical layout, lighting, noise, interruption frequency?
   • Equipment functioning and available?
   • Workload and fatigue levels?

5. Were there adequate barriers/safeguards in place?

   • Independent double-checks, forcing functions, redundancies?
   • Clinical decision support, checklists, standardized processes?
   • Were barriers bypassed, and if so, why?

Step 4: Root Cause Validation

Validate identified root causes against acceptance criteria:

A valid root cause must be:

• Specific: Clearly describes the systemic failure (not vague, e.g., "communication failure" must specify what communication, between whom, about what)
• Systemic: Addresses a system, process, or design issue (not individual performance alone)
• Actionable: The organization has the ability to implement a fix
• Evidenced: Supported by facts gathered during the investigation
• Foundational: Removal of this cause would prevent or significantly reduce recurrence

Root Cause Quality Test:

• If this root cause were eliminated, would the event still have occurred? (If yes, continue analysis)
• Is this root cause under organizational control? (If no, it is a contributing factor, not a root cause)
• Can we develop a feasible corrective action for this root cause? (If no, reframe)

Step 5: Corrective Action Development

Develop strong corrective actions for each root cause:

Action Strength Hierarchy (strongest to weakest):

Joint Commission Corrective Action Requirements:

• Actions must address identified root causes (not symptoms)
• Include at least one strong action for each sentinel event RCA
• Define measurable outcomes to evaluate effectiveness
• Assign responsibility and implementation timeline
• Include a plan to sustain the improvement

Step 6: Outcome Measures and Monitoring Plan

Define how corrective action effectiveness will be measured:

Outcome Measures:

• Process measure: Is the corrective action being implemented as designed? (compliance rate)
• Outcome measure: Has the adverse event type been reduced or eliminated? (recurrence rate)
• Balancing measure: Has the corrective action created any unintended negative consequences?

Monitoring Plan:

• Define measurement frequency (weekly during initial implementation, then monthly)
• Establish monitoring duration (minimum 12 months for sentinel event corrective actions)
• Identify responsible person for data collection and analysis
• Define success criteria (e.g., zero recurrence for 12 months)
• Plan for reassessment if corrective action is not achieving desired results

Step 7: RCA Report Compilation

Assemble the complete RCA document:

Required RCA Report Sections:

1. Event description: Factual summary with relevant clinical context
2. Event timeline: Chronological causal factor chart
3. Investigation process: Team members, interviews conducted, data reviewed
4. Root cause findings: Each root cause with supporting evidence and Five Whys chain
5. Contributing factors: Factors that contributed but are not root causes
6. Corrective action plan: Each action linked to a root cause, with owner, timeline, and measures
7. Monitoring plan: How effectiveness will be tracked
8. Risk reduction assessment: How corrective actions will reduce future risk
9. Leadership review: Sign-off by organizational leadership
10. Lessons learned: Key insights for organizational learning

Analysis Framework

VA NCPS RCA Process Flow

Examples

Example: Wrong-Site Surgery RCA

• Event: Left knee arthroscopy performed when right knee was indicated
• Severity: Sentinel event (wrong-site surgery)
• Timeline: Pre-op verification completed but laterality discrepancy not detected; surgical time-out performed but site marking not visible under draping
• Root causes identified:
  1. Pre-operative verification process did not include independent cross-check of imaging with consent and OR schedule (Process gap — no redundancy)
  2. Site marking was performed but not visible after draping, and time-out protocol did not require visualization of mark (Policy gap — incomplete protocol)
  3. OR schedule displayed abbreviated laterality ("L knee") that was ambiguous in context (System design — ambiguous information display)
• Corrective actions:
  1. (Strong) Implement hard-stop in OR system requiring imaging laterality confirmation before case can proceed
  2. (Strong) Revise draping protocol to ensure site mark remains visible; add marking verification to time-out checklist
  3. (Intermediate) Standardize OR schedule laterality display to full text with redundant notation
• Monitoring: Zero wrong-site events for 12 months; monthly time-out compliance audits

Guidelines

1. Focus on systems, not blame — RCA is a systems improvement methodology, not a disciplinary tool
2. Include at least one strong corrective action — Joint Commission will not accept RCAs with only weak actions
3. Complete within 45 business days — Joint Commission timeline for sentinel event RCA
4. Involve front-line staff — those closest to the work provide the most accurate insights
5. Validate root causes rigorously — a poorly identified root cause leads to ineffective corrective actions
6. Avoid "education only" as a sole corrective action — training alone does not prevent recurrence
7. Measure effectiveness — a corrective action without outcome measurement is incomplete

HIPAA Compliance Notes

• RCA investigation requires access to detailed PHI in medical records (45 CFR 164.501)
• RCA activities constitute quality improvement/healthcare operations under HIPAA (45 CFR 164.501)
• RCA documents containing PHI must be secured with access controls (45 CFR 164.312(a))
• Consider reporting to a Patient Safety Organization for federal privilege protections under the Patient Safety Act (42 CFR Part 3)
• De-identify RCA findings before sharing for organizational learning beyond the investigation team
• State peer review and quality improvement protections may apply to RCA documents — consult legal counsel
• Staff interviews during RCA should be conducted with awareness of confidentiality protections and limits
