  1. A resuscitation team reviews a Pareto chart of causes for delayed defibrillation. The Pareto principle suggests the team should prioritize:

    Answer: The vital few causes responsible for approximately 80% of the delays

    The Pareto principle holds that roughly 80% of problems stem from 20% of causes — the Pareto chart visually identifies those 'vital few' causes to target for maximum impact.

  2. In ECC data reporting, 'event survivorship bias' would occur if an analyst:

    Answer: Includes only patients who survived to hospital admission in the denominator for survival rates

    Survivorship bias occurs when the analysis denominator includes only patients who reached a certain point (e.g., hospital admission), excluding those who died earlier and distorting true survival rates.

  3. A hospital's IHCA (in-hospital cardiac arrest) team wants to compare its survival rate to national benchmarks. The most appropriate national benchmark source is:

    Answer: Get With The Guidelines–Resuscitation (GWTG-R) registry national data

    The American Heart Association's GWTG-Resuscitation registry provides the largest national IHCA dataset with risk-adjusted benchmarks specifically for in-hospital cardiac arrest outcomes.

  4. Which calculation correctly determines the 'chest compression fraction (CCF)' for a 15-minute resuscitation with 11 minutes of compressions?

    Answer: 11 / 15 = 0.73 (73%)

    CCF = time compressions were performed ÷ total resuscitation time = 11 ÷ 15 = 0.73, meaning compressions occurred during 73% of the resuscitation.

  5. When an EMS system implements a new CPR feedback device and observes improved outcomes, which type of study design provides the strongest evidence that the device caused the improvement?

    Answer: Randomized controlled trial or stepped-wedge cluster trial

    Randomized or stepped-wedge cluster trials provide the strongest causal evidence by controlling for confounding variables and secular trends that affect observational before-after comparisons.

  6. A QI report shows mean CPR compression rate of 112/min across 300 resuscitations. Per 2020 AHA guidelines, this rate is:

    Answer: Within the recommended range of 100-120/min

    The 2020 AHA guidelines recommend an adult CPR compression rate of 100-120 per minute; 112/min falls within this range.

  7. In a multisite cardiac arrest quality improvement collaborative, 'shared learning' is best facilitated by:

    Answer: Blinded aggregate benchmarking reports allowing sites to compare their performance to peers

    Blinded aggregate benchmarking allows each site to see its own performance relative to peers without revealing individual site identities, fostering competition and improvement while protecting confidentiality.
