Center variation in hospital costs for patients undergoing congenital heart surgery.

Background: Congenital heart disease consumes significant health care resources; however, there are limited data regarding factors affecting resource utilization. The purpose of this study was to evaluate variation between centers in total hospital costs for 4 congenital heart operations of varying complexity and associated factors.

Methods And Results: The Premier Database was used to evaluate total cost in children undergoing isolated atrial septal defect (ASD) repair, ventricular septal defect (VSD) repair, tetralogy of Fallot (TOF) repair, or arterial switch operation (ASO) from 2001 to 2007.

Rhythm versus rate control in the contemporary management of atrial fibrillation in-hospital.

Little is presently known regarding whether a rhythm-control or a rate-control strategy is more frequently used in patients hospitalized for atrial fibrillation (AF). This study was conducted to assess patient and physician characteristics associated with each treatment strategy and with the use of anticoagulants. Hospitalizations for primary diagnoses of AF were examined using hospital claims from January 2000 to December 2004.
