Table 3. Multiple logistic regression model with favourable neurological outcome at hospital discharge as the dependent variable.
Independent variablea | Odds ratio | 95% confidence interval | p value |
---|---|---|---|
Pulmonary artery catheter in place at time of arrest | 9.85 | 2.00–48.65 | 0.005 |
Intravenous antiarrhythmics in place at time of arrest | 2.93 | 1.38–6.24 | 0.005 |
Favourable neurological status 24 h before cardiac arrestb | 2.88 | 1.72–4.85 | <0.001 |
Myocardial infarction, this admission | 2.73 | 1.43–5.22 | 0.002 |
VFc/ Pulseless VTd | 2.58 | 1.50–4.47 | 0.001 |
Male | 1.89 | 1.08–3.30 | 0.025 |
Age (year) | 0.98 | 0.96–0.99 | 0.009 |
CPRe duration (min) | 0.94 | 0.91–0.96 | <0.001 |
Cardiopulmonary resuscitation during or before 2010 | 0.56 | 0.32–0.97 | 0.037 |
Renal insufficiency | 0.45 | 0.26–0.77 | 0.004 |
Baseline depression in CNSf function | 0.29 | 0.15–0.57 | <0.001 |
Metastatic or hematologic malignant disease | 0.08 | 0.02–0.32 | <0.001 |
Goodness-of-fit assessment: n = 796, adjusted generalised R2 = 0.4; the estimated area under the receiver operating characteristics curve = 0.86, with 95% confidence interval 0.83–0.90; and the Hosmer and Lemeshow goodness-of-fit Chi-Squared test p = 0.71.
a The display of independent variables is arranged by descending order of odds ratio. The bold-typed variables were also components of Cardiac Arrest Survival Post-resuscitation In-hospital (CASPRI) score.
b Patients with cerebral performance score 1 or 2
c VF, ventricular fibrillation
d VT, ventricular tachycardia
e CPR, cardiopulmonary resuscitation
f CNS, central nervous system
