From: Predictors of cardiopulmonary arrest outcome in a comprehensive cancer center intensive care unit

Variable CPR failure OR(CI) ICU death OR(CI) Hospital death OR(CI)
Age 0.99 (0.97–1.02) 0.99 (0.94–1.04) 0.98 (0.93–1.04)
Gender 1.6 (0.68–3.6) 1.7 (0.41–7.4) 0.82 (0.14–4.7)
Hematologic malignancies 0.39 (0.17–0.92) No estimate No estimate
Progressing or relapsed tumor 0.74 (0.24–2.3) 4.1 ( 0.64–27) 5.3 (0.46–62)
Acute kidney injury * 1.7 (1.1–2.6) 1.7 (0.65–4.7) 6.6 (0.56–79)
Being on MV 3.8 (1.3–11.0) 3.2 (0.70–15) 5.5 (1.0–30)
Refractory shock** 4.7 (1.8–12.0) 6.4 (0.75–50) 5.7 (0.34–97)
Lactate ≥ 4 1.1 (0.95–1.2) 1.4 (0.82–2.5) 1.7 (0.67–4.5)
ICU LOS before CPA 1.00 (0.99–1.00) 1.01 (0.99–1.02) 1.17 (0.88–1.58)
Anticipated CPA*** 1.6 (0.68–3.8) 14 (1.6–121) 8.6 (0.93–81)
Length of CPR 1.1 (1.1–1.2) 1.1 (1.0–1.3) 1.3 (1.1–1.7)
  1. CI: confidence interval; CPA: cardiopulmonary arrest; CPR: cardiopulmonary resuscitation; ICU: intensive care unit; LOS: length of stay; MV: mechanical ventilation; OR: odds ratio.
  2. *Acute kidney injury: the abrupt (within 48 hours) absolute increase in serum creatinine ≥ 26.4 micro moles/L, a percentage increase in serum creatinine of ≥ 50%, or a urine output of < 0.5 milliliter/kilogram/hour for 6 hours.
  3. **Refractory shock: requiring 2 or more vasopressors to maintain a mean arterial pressure of above 65.
  4. ***Anticipated CPA: cardiopulmonary arrest in patients with refractory shock, refractory respiratory failure and/or multiorgan dysfunction syndrome.
