Area Deprivation Index Correlates with a Lower Rate of Hospital Readmission from the Emergency Room following Endoscopic Skull Base Surgery

Background: The area deprivation index (ADI) is a validated measure of socio-geographical disadvantage calculated from United States Census data that has been correlated with a variety of poor medical and surgical outcomes. Healthcare utilization, such as emergency department (ED) visits, and hospital readmission within 30 days of surgery are nationally tracked metrics of healthcare quality. Numerous risk factors have been identified for ED visits and readmission after endoscopic skull base surgery (ESBS). However, ADI has never been studied in the context of postoperative outcomes in ESBS.
