🚨 Patient Safety Incident Investigation — Root Cause Analysis + System Fix
The structured patient safety investigation covering the RCA (Root Cause Analysis) methodology, the just-culture framework distinguishing system failures from individual errors, 5-Whys technique, and the prevention-focused approach that drives learning vs. blame.
Why this is epic
Patient safety incidents reveal system failures + require structured investigation. This Original produces RCA + just culture framework + system fixes preventing recurrence.
Names 5 investigation failures (blame-focused, incomplete, single-cause assumption, no systems thinking, no follow-through).
Produces complete framework. Just-culture principles.

Incident Investigation: 10x Insulin Dose Error, Harm Resulting, Formal RCA
A patient safety incident investigation produces systematic root cause analysis + prevention framework. Your situation — medication error with patient harm — warrants formal RCA. This framework: timeline + 5-Whys + just culture + system fixes.
Immediate Response (Completed + Next Steps)
Already Done:
- Patient treatment + stabilization
- Incident report filed
- Staff pulled from patient care
Next Steps Within 24 Hours:

- Leadership informed
- Resources arranged for involved staff (EAP, peer support)
Within 48 Hours:
- Preliminary interview with involved staff (supportive, not accusatory)
- Document secure preservation
- Medications + equipment secured as evidence
Timeline Reconstruction (Objective)
Factual timeline (from records + interviews):
| Time | Event |
|---|---|
| Admission -48h | Patient admitted for DKA |
| H-2:00 | Intern MD orders 'Humulin R 4 units IV' |
| H-1:30 | Pharmacy verifies order |
| H-1:15 | Order transmitted to medication administration system |
| H-0:30 | RN accesses Pyxis, retrieves insulin vial |
| H-0:15 | RN draws up medication |
| H-0:10 | RN administers to patient |
| H | Check glucose at 30 min post-administration |
| H+0:30 | Glucose 35 mg/dL noted — severe hypoglycemia |
| H+0:35 | D50 administered + rapid response called |
| H+0:45 | Patient stabilizing |
| H+4:00 | Patient fully recovered + continued hospital course |
Key moment of error: between order + administration. Something caused 4 units → 40 units.
Root Cause Analysis (5-Whys + Fishbone)
5-Whys Analysis
Problem: patient received 40 units insulin instead of 4 units.
Why 1: Why did RN administer 40 units?
Answer 1: RN calculated dose as '40 units' when reading '4 units' from syringe labeling.
Why 2: Why did RN calculate 40 units?
Answer 2: Confusing vial labeling + time pressure led to misreading.
Why 3: Why was vial labeling confusing?
Answer 3: Insulin concentration labeling inconsistent — some 100 units/mL, some 500 units/mL. Institution has both.
Why 4: Why do we have two concentrations?
Answer 4: Legacy workflow — high-dose insulin cases used concentrated insulin. But safety protocols not updated.
Why 5: Why weren't safety protocols updated?
Answer 5: No systematic review of medication safety controls when products introduced.
Multiple 5-whys paths often needed. Other branches:
Why didn't pharmacy catch it?
- Pharmacy verified order, not dose math
- Automation limitations
- No independent check on dose math
Why didn't independent nurse check catch it?
- Second nurse check required for insulin
- Happened, but not for dose calculation verification
- Second nurse confirmed vial identity only
Why did intern MD write ambiguous order?
- Order was correct as written ('4 units')
- Error occurred downstream
Fishbone Diagram Categories
Methods/Procedures:
- Inconsistent insulin concentration inventory
- Second nurse check protocol inadequate
- Independent dose verification missing
People:
- RN training on concentrated insulin may be inadequate
- Communication breakdown in verification
Equipment/Systems:
- Pyxis dispensing same-looking vials
- EHR not flagging concentration differences
Environment:
- Time pressure
- Shift change potentially
- Distractions
Materials:
- Similar-looking insulin vials (100 vs. 500 units/mL)
- Labeling not distinct
Just Culture Assessment
Three behavior categories:
Human Error (systemic issues)
Definition: inadvertent slip in attention, mental model mismatch
Assessment of RN:
- Misread vial during dose preparation
- System-enabled error (confusing labels, inadequate safeguards)
- Not reckless
- Would likely happen to another competent RN in same situation
Classification: Human error enabled by system failures.
At-Risk Behavior
Definition: choice taking shortcuts despite known risk
Not clearly present here. No evidence RN knowingly bypassed safety checks.
Reckless Behavior
Definition: conscious disregard of substantial risk
Not present. No evidence of disregard.
Just Culture Response
For human error (this case):
- Console + support
- Focus on system fix
- No punitive action for RN
- Learning opportunity
For at-risk behavior:
- Coach + educate
- Understand motivations
- Address gaps
For reckless behavior:
- Discipline appropriate
- But not this case
Staff wellbeing:
- RN likely traumatized
- EAP + peer support
- Protected time off if needed
- Return-to-work support
Contributing Factors
Primary (System-Level):
1. Dual insulin concentrations in inventory — enabled mix-up
2. Insufficient labeling differentiation — similar vials
3. Second-check protocol gaps — verified vial identity but not dose math
4. EHR not flagging concentration — missed safety opportunity
5. Pyxis dispensing confusion — similar storage
Secondary (Process-Level):
6. Time pressure during shift — busy unit
7. Training on concentrated insulin — may have been inadequate
8. High-risk medication protocols — insulin should have extra safeguards
Tertiary (Patient-Level):
9. Complex patient — DKA management + insulin titration
10. Multiple care providers — handoff points
System Fixes
Priority 1: Single Insulin Concentration
Action: standardize to 100 units/mL only (or 500 with separate storage).
Rationale: eliminates confusion.
Implementation:
- Phase out 500 units/mL from routine inventory
- Dedicated storage for 500 units/mL (if kept)
- Update pharmacy formulary
- Staff communication
Timeline: 60-90 days.
Priority 2: Enhanced Labeling + Dispensing
Action: distinct labeling + Pyxis dispensing safeguards.
Implementation:
- High-visibility warning labels on concentrated insulin
- Pyxis requires special authorization for concentrated
- EHR alerts for concentration differences
Timeline: 30-60 days.
Priority 3: Strengthened Second Check
Action: insulin administration requires full dose verification (not just vial check).
Implementation:
- Two RN verification: dose math + vial + patient
- Clinical decision support for dose ranges
- Insulin administration checklist
Timeline: 30 days.
Priority 4: EHR Decision Support
Action: dose-range checking + concentration warnings.
Implementation:
- Alerts for doses outside expected range
- Concentration confirmation at order entry
- Dose verification at medication administration
Timeline: 90 days (IT development).
Priority 5: Training + Competency
Action: insulin-specific training + competency validation.
Implementation:
- Annual insulin administration competency
- Scenario-based training
- Regular audits
Timeline: ongoing.
Priority 6: Near-Miss Tracking
Action: track + review insulin-related near misses systematically.
Implementation:
- Improve reporting culture
- Review monthly
- Trend analysis
Timeline: immediate start.

Key Takeaways
- Root causes: system failures (dual insulin concentrations, inadequate labeling, gaps in second-check process, EHR not flagging). Not individual RN error. Just culture response.
- 6 system fixes prioritized: (1) single insulin concentration, (2) enhanced labeling, (3) strengthened second check, (4) EHR decision support, (5) training, (6) near-miss tracking. Implementation timeline 30-90 days.
- Just culture assessment: human error enabled by system failures. Not at-risk or reckless. Staff support + system fixes focus. No punitive action against RN.
- Follow-through essential. 30/60/90 day milestones + 6-month + 12-month effectiveness evaluation. Recommendations without implementation = waste.
- Learning dissemination internal + external. De-identified sharing prevents recurrence at peer institutions. Regulatory reporting per requirements. Transparency builds trust.
Common use cases
- After patient safety events
- Quality improvement teams
- Hospital incident command
- Risk management
- Medical error investigations
