Anesthesia Technique in COVID-19 Positive Hip Fracture Patients

Patients with COVID undergoing hip fracture repair have high mortality rates. If spinal anesthesia is associated with decreased rates of mortality, this study could provide hypothesis generating data for prospective studies. Investigators hypothesize that spinal anesthesia (SA) is associated with decreased mortality compared to general anesthesia (GA) for patients undergoing hip fracture surgery. The primary objective is to determine for patients undergoing hip surgery with COVID-19 infection, whether SA, as compared to GA, is associated with a lower rate of mortality 30 days postoperatively. The secondary objective is to determine whether SA, as compared to GA, is associated with a lower rate of morbidity 30 days postoperatively. Investigators will be analyzing a data set provided by the National Surgical Quality Improvement Program (NSQIP). Descriptive statistics will be performed. Multivariable logistic regression will be performed for the primary and secondary objectives.
