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 ACS NSQIP. The PUF contains patient level, aggregate data and does not identify hospitals, healthcare 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, etc) of ACS NSQIP participating hospitals.
The 2010 PUF contains 363,431 cases submitted in 2010 from 258 participating sites. Four other separate PUFs containing 152,490 cases submitted in 2005 and 2006 by 121 sites, 211,407 cases submitted in 2007 by 183 sites, 271,368 cases submitted in 2008 from 211 participating sites, and 336,190 cases submitted in 2009 by 237 sites are also available. Only cases included in risk-adjustment calculations are in this database. For background information on the case inclusion/exclusion criteria and the data collection and submission processes, please visit the Program Specific page. Each case contains 240 HIPAA compliant variables. Variable formats, variable definitions, and other supporting information are available in the User Guides: 2011, 2010, 2009, 2008, 2007, and 2005-06. The data files are made available in a delimited text, SAS, and SPSS file type.
To request a copy of the PUF, individuals (data recipients) must agree to comply with the terms and conditions set forth in the Data Use Agreement, provide contact information, and complete a short online questionnaire. Once the information provided by the data recipient is received and processed by ACS NSQIP staff, a website address will be submitted electronically to the data recipient. The data recipient will then have 10 days (240 hours) to visit the website and download the data file.
