Table 4. Characteristics of Vizient CDB/RM hospitals, 2012.
| Median (IQR) | Min | 10th Pct | 90th Pct | Max | |
|---|---|---|---|---|---|
| Total Patients | 22,869 (12,952–32,892) | 1,817 | 7,942 | 48,325 | 112,379 |
| Cardiac Arrest Cases | 162 (91–250) | 25 | 39 | 369 | 768 |
| Number of Cardiac Arrest Patients Surviving | 66 (29–108) | 6 | 14 | 160 | 364 |
| Observed Cardiac Arrest Survival (%) | 40.5 (34.6–46.6) | 17.1 | 28.0 | 52.3 | 74.1 |
| RSSR (%) | 38.2 (34.1–42.5) | 22.0 | 29.7 | 46.2 | 59.6 |
N = 179 Vizient CDB/RM hospitals. Excludes hospitals with fewer than 25 eligible cardiac arrest cases. Excluding those aged <18 years, prisoners, transfers, and hospice patients. IQR = interquartile range, RSSR = risk-standardized survival rate. RSSRs estimated using Empirical Bayes log odds estimates obtained from a random intercept logistic regression model adjusted for expected mortality. All RSSR estimates were transformed to percentages and are provided for discharges at the average expected mortality value (probability of mortality = 0.24).
