  1. A QI team wants to determine if a new dispatcher CPR protocol caused a statistically significant increase in bystander CPR rates. Which analysis is most appropriate?

    Answer: Chi-square test comparing pre- and post-implementation proportions

    A chi-square test compares proportions (rates) between two groups, making it appropriate for assessing whether bystander CPR rates changed significantly before and after an intervention.

  2. Which report format is required by the CARES (Cardiac Arrest Registry to Enhance Survival) registry for OHCA data submission?

    Answer: Standardized Utstein-based data elements

    CARES uses standardized Utstein-based data elements to ensure uniform, comparable cardiac arrest data collection across participating EMS agencies and hospitals.

  3. A run chart of monthly ROSC rates shows 8 consecutive data points above the median line. According to run chart rules, this most likely indicates:

    Answer: A non-random signal suggesting a real process shift

    Eight or more consecutive points on the same side of the median is a standard run chart rule signaling a non-random shift in the process.

  4. When benchmarking STEMI reperfusion times, why must raw door-to-balloon times be adjusted before comparing hospitals?

    Answer: To control for case mix factors like transfer patients and off-hours presentations

    Transfer patients and off-hours (nights/weekends) cases systematically inflate door-to-balloon times, so risk adjustment is needed for fair comparisons.

  5. Which statistical process control (SPC) chart is best suited for monitoring monthly cardiac arrest survival rates over time?

    Answer: P-chart (proportion chart)

    A P-chart monitors proportions (like survival rate) over time and includes control limits to distinguish common cause from special cause variation.

  6. An EMS medical director reviews data showing that CPR compression depth averages 45 mm across 200 resuscitations. According to 2020 AHA guidelines, this performance is:

    Answer: Suboptimal — below the recommended minimum depth of 50 mm (2 inches)

    The 2020 AHA guidelines recommend adult compression depth of at least 2 inches (50 mm), so a 45 mm average falls below the recommended minimum.

  7. In post-cardiac arrest care audit, 'favorable neurological outcome' is most commonly defined using which standardized scale?

    Answer: Cerebral Performance Category (CPC) score 1 or 2

    CPC 1 (good cerebral performance) and CPC 2 (moderate disability but independent) together define 'favorable neurological outcome' in most ECC and resuscitation registries.
