BACKGROUND: Previous studies examining high-frequency ED utilization have primarily used single-center data, potentially leading to ascertainment bias if patients visit multiple centers. The goals of this study were (1) to create a predictive model to prospectively identify patients at risk of high-frequency ED utilization for asthma, and (2) to examine how that model differed using state-wide versus single-center data. METHODS: To track ED visits within a state, we analyzed 2011-2013 data from the New York State Healthcare Cost and Utilization Project (HCUP) State Emergency Department Databases (SEDD)...

BACKGROUND: Carotid body tumors (CBTs) are rare entities for which surgical resection remains the gold standard. Given their hypervascularity, preoperative embolization is often used; however, controversy exists over whether a benefit is associated. Proponents of embolization argue that it minimizes blood loss and complications. Critics argue that cost and stroke outweigh benefits. This study aimed to investigate the impact of embolization on outcomes following CBT resection. METHODS: Patients undergoing CBT resection were identified using the Healthcare Cost and Utilization Project State Inpatient Database for 5 states between 2006 and 2013...
