All pediatric patients who underwent cardiac surgery and were transferred alive from the PICU were included.

Over half (12\/23, 52.2%) of these readmissions occurred within 48\u2005h of PICU discharge. Univariate analysis identified preoperative arrhythmias (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.037) and postoperative single-ventricle physiology (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.024) as potential risk factors for readmission.

Although preoperative vasopressor requirement, postoperative altered ventricular function and known pleural effusion at PICU discharge were not significantly associated with PICU readmission, these factors showed a trend toward significance. After multivariate analysis, postoperative single-ventricle physiology remained the sole independent risk factor associated with unplanned PICU readmission with an odds ratio of 8.6 (95% confidence
