American College Of Surgeons - Inspiring Quality: Highest Standards, Better Outcomes

ACS NSQIP Participant Use Data File

The Participant Use Data File (PUF) is a Health Insurance Portability and Accountability Act (HIPAA)-compliant data file containing cases submitted to the American College of Surgeons National Surgical Quality Improvement Program® (ACS NSQIP®). The PUF contains patient-level, aggregate data and does not identify hospitals, health care providers, or patients. The intended purpose of this file is to provide researchers at participating sites with a data resource they can use to investigate and advance the quality of care delivered to the surgical patient through the analysis of cases captured by ACS NSQIP. The PUF is provided at no additional cost to employees (surgeons, Surgical Clinical Reviewers, researchers, etc.) of ACS NSQIP-participating hospitals.

The 2015 PUF contains 885,502 cases submitted from 603 NSQIP-participating sites. Nine other separate PUFs, containing a rich database of more than 3.7 million cases, are also available. Only cases included in corresponding Semiannual Report (SAR) risk-adjustment calculations are in the PUF datasets. For background information on the case inclusion/exclusion criteria and the data collection and submission processes, please visit the ACS NSQIP Program Specific page. Variable formats, variable definitions (which can change from year to year), and other supporting information are available in the PUF User Guides. The data files are made available in a delimited text, SAS, and SPSS file type.
