Unanticipated hospital admission in pediatric patients with congenital heart disease undergoing ambulatory noncardiac surgical procedures.

BACKGROUND: An increasing number of surgical and nonsurgical procedures are being performed on an ambulatory basis in children. Analysis of a large group of pediatric patients with congenital heart disease undergoing ambulatory procedures has not been undertaken.

AIMS: The objective of this study was to characterize the profile of children with congenital heart disease who underwent noncardiac procedures on an ambulatory basis at our institution, to determine the incidence of adverse cardiovascular and respiratory adverse events, and to determine the risk factors for unscheduled hospital admission.

METHODS: This is a retrospective study of children with congenital heart disease who underwent noncardiac procedures on an ambulatory basis in a single center. Using the electronic preoperative anesthesia evaluation form, we identified 3010 patients with congenital heart disease who underwent noncardiac procedures of which 1028 (34.1%) were scheduled to occur on an ambulatory basis. Demographic, echocardiographic and functional status data, cardiovascular and respiratory adverse events, and reasons for postprocedure admission were recorded. Univariable analysis was conducted.

RESULTS: The unplanned hospital admission was 2.7% and univariable analysis demonstrated that performance of an echocardiogram within 6 mo of the procedure and procedures performed in radiology were associated with postoperative admission. Cardiovascular adverse event incidence was 3.9%. Respiratory adverse event incidence was 1.8%.

CONCLUSION: Ambulatory, noncomplex procedures can be performed in pediatric patients with congenital heart disease and good functional status with a relatively low unanticipated hospital admission rate.
