Abstract

BACKGROUND:

Factors leading to cardiac intensive care unit (CICU) readmission and the impact on mortality have yet to be well delineated. We sought to define the prevalence and outcome for unscheduled CICU readmission. Secondary objectives were to identify indications and risk factors for unscheduled CICU readmission.

METHODS:

Retrospective analysis of prospectively collected registry data at a tertiary care children's hospital. Pediatric and adult patients with congenital and acquired heart disease who survived to initial CICU discharge were included. Patients with unexpected return to the CICU for acute change in clinical status were defined as unscheduled readmissions.

RESULTS:

Of the 645 discharges that met inclusion criteria, 37 resulted in unplanned readmission to the CICU. Patients requiring unscheduled readmission had higher mortality rates (16.2% vs 0.5%, P < .0001). Cardiac symptoms were the most common reason for readmission. On multivariate analysis, genetic anomaly (P = .001) and longer length of stay (LOS) during the index CICU admission (P = .01) were independently associated with readmission. For surgical patients, genetic anomaly (P = .001), single-ventricle anatomy (P = .05), and longer surgical support time (P < .001) were independently associated with readmission.

CONCLUSION:

Unscheduled readmission to the CICU within the same hospitalization was uncommon but associated with a higher mortality rate. Genetic anomaly and longer initial LOS were important risk factors for the entire cohort. Single-ventricle anatomy and longer intraoperative course were risk factors for surgical readmissions.
