ECC Data Analysis & Reporting 2

Question 1

In a cardiac arrest registry, which metric best reflects the quality of post-resuscitation care?

Accepted Answer

Survival to hospital discharge with favorable neurological outcome

Answer

Survival to hospital discharge with favorable neurological outcome (CPC 1-2) is the gold-standard outcome metric because it captures both survival and meaningful recovery.

Question 2

A hospital's Utstein-style report shows a 10% gap between ROSC rate and survival to discharge. This gap most likely reflects deficiencies in:

Accepted Answer

Post-resuscitation care protocols

Answer

The gap between ROSC and discharge survival is largely attributable to post-resuscitation care quality, including targeted temperature management and hemodynamic optimization.

Question 3

When analyzing EMS response time data, which statistical measure is most appropriate for a dataset with significant outliers?

Accepted Answer

Median

Answer

Median is preferred over mean for skewed datasets with outliers because it represents the central value without being distorted by extreme values.

Question 4

A QI committee notes that CPR compression fraction improved from 55% to 72% over 12 months. Which data source is most reliable for measuring CPR compression fraction?

Accepted Answer

Accelerometer-equipped defibrillator download data

Answer

Accelerometer data from code-capable defibrillators provides objective, time-stamped CPR quality metrics including compression fraction, rate, and depth.

Question 5

Which Utstein variable is used to stratify OHCA outcomes to enable meaningful hospital-to-hospital comparisons?

Accepted Answer

Witnessed status and initial rhythm

Answer

Witnessed status and initial rhythm (shockable vs. non-shockable) are core Utstein stratifiers that allow risk-adjusted outcome comparisons across systems.
