CI: confidence interval; CPA: cardiopulmonary arrest; CPR: cardiopulmonary resuscitation; ICU: intensive care unit; LOS: length of stay; MV: mechanical ventilation; OR: odds ratio.
*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.
**Refractory shock: requiring 2 or more vasopressors to maintain a mean arterial pressure of above 65.
***Anticipated CPA: cardiopulmonary arrest in patients with refractory shock, refractory respiratory failure and/or multiorgan dysfunction syndrome.
