CIR CIR Quality Improvement & Patient Safety 1 — Questions and Answers
Question 1: In a cardiac catheterization lab, a 'time-out' performed immediately before a procedure primarily serves to:
- Calculate the patient's estimated radiation dose for the case
- Verify correct patient identity, procedure, site, and implant availability (Correct answer)
- Confirm anticoagulation has been administered
- Review the patient's prior angiographic images
Correct answer: Verify correct patient identity, procedure, site, and implant availability
The pre-procedure time-out is a Joint Commission-mandated Universal Protocol step ensuring the correct patient is receiving the correct procedure at the correct site with all necessary resources ready.
Question 2: Which metric is most commonly used to benchmark door-to-balloon (D2B) time quality in STEMI care?
- Median D2B time ≤ 60 minutes
- Mean D2B time ≤ 90 minutes for ≥ 75% of eligible patients (Correct answer)
- 90th-percentile D2B time ≤ 120 minutes
- Zero cases exceeding 60 minutes per quarter
Correct answer: Mean D2B time ≤ 90 minutes for ≥ 75% of eligible patients
The ACC/AHA and CMS quality benchmark targets a median D2B time ≤ 90 minutes for at least 75% of eligible STEMI patients presenting to PCI-capable hospitals.
Question 3: A near-miss event in the cath lab is best defined as:
- An adverse event that results in permanent patient injury
- An unplanned event that did not reach the patient but had the potential to cause harm (Correct answer)
- Any deviation from the standard procedure protocol
- Equipment failure that required the case to be aborted
Correct answer: An unplanned event that did not reach the patient but had the potential to cause harm
Near-miss events are unplanned incidents that did not result in patient harm but could have — reporting them is critical for proactive safety system improvement.
Question 4: Root cause analysis (RCA) in cath lab quality improvement is triggered primarily by:
- Any procedure lasting longer than three hours
- Sentinel events, serious adverse events, or significant near-misses (Correct answer)
- Quarterly audits of contrast utilization rates
- Cases requiring unplanned intensivist consultation
Correct answer: Sentinel events, serious adverse events, or significant near-misses
RCA is a structured retrospective investigation conducted after sentinel events or serious patient safety incidents to identify contributing system factors and prevent recurrence.
Question 5: Which quality indicator specifically tracks unplanned coronary artery bypass grafting (CABG) following percutaneous coronary intervention?
- Contrast-induced nephropathy rate
- Emergency CABG rate post-PCI (Correct answer)
- Major adverse cardiovascular events (MACE) at 30 days
- Stent thrombosis rate at 12 months
Correct answer: Emergency CABG rate post-PCI
Emergency CABG rate after PCI is a key procedural complication metric tracked by the ACC National Cardiovascular Data Registry (NCDR) as a quality and safety indicator.
Question 6: The ALARA principle in cath lab radiation safety stands for:
- All Labs Are Responsible for Accountability
- As Low As Reasonably Achievable (Correct answer)
- Accurate Limit And Radiation Adjustment
- Automated Low-dose Acquisition and Recording Algorithm
Correct answer: As Low As Reasonably Achievable
ALARA (As Low As Reasonably Achievable) is the guiding principle for radiation protection, requiring that exposure to patients and staff be minimized while maintaining diagnostic and therapeutic image quality.
