CHSP - Certified Healthcare Safety Professional Incident Investigation and Analysis 2

Question 1

A root cause analysis (RCA) team is mapping the sequence of events that led to a wrong-site surgery.
Which tool is MOST appropriate for visually displaying the timeline of contributing factors and their causal relationships?

Accepted Answer

Event and causal factor (ECF) chart

Answer

Failure Mode and Effects Analysis (FMEA)

Answer

Cause-and-effect (fishbone) diagram

Answer

Pareto chart

Question 2

During an incident investigation debrief, a team member states, 'The nurse should have just paid more attention.' A skilled facilitator should redirect this statement by applying which core principle of a systems-based investigation?

Accepted Answer

Most errors result from predictable human failure within flawed systems, not malicious intent

Answer

Individual accountability must always precede system analysis

Answer

Human error is the root cause in the majority of preventable incidents

Answer

Cognitive bias is irrelevant once a factual timeline is established

Question 3

After completing a root cause analysis, which action is the HIGHEST priority to ensure the investigation produces lasting improvement?

Accepted Answer

Assigning corrective action items with specific owners and due dates, then tracking to completion

Answer

Filing the final RCA report with The Joint Commission within 45 days

Answer

Distributing an anonymous summary of findings to all clinical staff via email

Answer

Re-educating the involved staff members on the relevant policy

Question 4

A safety officer is selecting an investigation methodology for a high-hazard process before an adverse event occurs. Which methodology is specifically designed for this PROACTIVE purpose?

Accepted Answer

Failure Mode and Effects Analysis (FMEA)

Answer

Root Cause Analysis (RCA)

Answer

Apparent Cause Analysis (ACA)

Answer

Significant Incident Review (SIR)

Question 5

When collecting witness statements during a patient safety incident investigation, the investigator should document them as close to the event as possible primarily because:

Accepted Answer

Human memory is reconstructive and details fade or become contaminated rapidly after an event

Answer

Regulatory agencies require statements within 24 hours of every incident

Answer

Early statements can be used to discipline staff before the full investigation concludes

Answer

Witnesses are more cooperative before union representatives become involved

Question 6

A healthcare organization notices that incident reports from one nursing unit are consistently 40% lower than comparable units, yet that unit's patient outcome data shows a similar rate of adverse events. The safety officer's MOST appropriate next step is to:

Accepted Answer

Investigate potential underreporting barriers such as fear of blame, unclear reporting processes, or belief that reporting 'doesn't matter'

Answer

Reward the unit for its apparently low incident rate

Answer

Assume the outcome data is inaccurate and report the discrepancy to administration

Answer

Reduce the incident reporting requirement for that unit since it appears low-risk
