TY - JOUR T1 - FInding pure and simple truths with administrative data AU - Sarrazin M, Rosenthal GE Y1 - 2012/04/04 N1 - 10.1001/jama.2012.404 JO - JAMA SP - 1433 EP - 1435 VL - 307 IS - 13 N2 - Administrative data have been used to assess quality of care and variations in health care delivery for nearly 3 decades. Indeed, administrative data have provided important insights on racial disparities in care,1 geographic differences in utilization,2 and variations in outcomes across hospitals.3 In the absence of national clinical registries, administrative data will continue to be an important source of information about health care delivery in the United States because of their ready availability, low cost, and ability to span multiple years and health care settings. Moreover, in contrast to data from randomized controlled trials, administrative data reflect real-world treatment settings and unselected populations. However, users must be aware of the inherent limitations of administrative data to avoid erroneous conclusions.
