The National Anesthesia Clinical Outcomes Registry (NACOR) of the Anesthesia Quality Institute (AQI) is the largest national anesthesia database available. NACOR is a voluntary data submission registry with the goal of facilitating the evaluation of quality in anesthesia care both locally and nationally. The registry is available to anesthesia providers in the US and represents an opportunity to survey data from all provider types, from private practices to large-scale hospitals. The spectrum advantageously provides a glimpse into many sections of anesthetic care. The AQI database is de-identified and contains patient demographics, billing, procedural, diagnostic, and provider information. For additional information regarding NACOR please visit this website.
