NIS vs SAGES: a comparison of national and voluntary databases.
Surg Endosc. 2006; (7): 1124-8
Surgical outcomes are increasingly examined in an effort to improve quality and reduce medical error. The Nationwide Inpatient Sample (NIS) is a retrospective, claims-derived and population-based database and the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) Outcomes Project is a prospective, voluntary and specialty surgeon database. We hypothesized that these two sources of outcome data would differ in regard to a single, commonly performed procedure.
