This study evaluated the expanding role of freestanding ambulatory surgery centers in pediatric fracture care based on the only national ambulatory surgery database within the United States. Released by the Centers for Disease Control and Prevention in 1996 and again in 2006, these reports were used to estimate the volume of outpatient pediatric operative fracture care in the United States over a decade, based on International Classification of Diseases, Ninth Revision, Clinical Modification, procedure codes. Particular attention focused on the prevalence of open vs closed vs percutaneous fixation. The estimated number of pediatric patients who presented to outpatient facilities and required operative fracture care between 1996 and 2006 increased by 88%, from 74,577 ± 4663 to 140,152 ± 9138. During this time, the use of outpatient surgical services for pediatric fractures increased threefold, from 10% ± 1% in 1996 to 32% ± 2% in 2006. An even greater preference for freestanding ambulatory surgery centers was observed during this same time by a factor of 7, from 3% ± 1% to 21% ± 4%. Additionally, a trend toward higher volumes of open and percutaneous fixation in freestanding ambulatory surgery centers and not in hospital-associated outpatient centers was observed. This study showed the expanding role of freestanding ambulatory surgery centers in the surgical treatment of pediatric fractures based on data from the only national ambulatory surgery database in the United States. The proportion of open and percutaneous treatment vs closed reduction of fractures in these facilities also greatly increased. Further study is needed to evaluate clinical outcomes and determine which fractures are most appropriately treated in the ambulatory vs hospital setting.
