The Participant Use Data File (PUF) is a Health Insurance Portability and Accountability Act (HIPAA)-compliant data file containing cases submitted to the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP®) Data Registry. 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 metabolic and bariatric surgical patient through the analysis of cases captured by MBSAQIP.
The PUF is provided at no additional cost to employees (surgeons, researchers, bariatric program staff, etc) of MBSAQIP participant centers. With over 200,000 metabolic and bariatric cases captured each year, the MBSAQIP PUF is the largest, bariatric-specific, clinical dataset in the country and serves as an invaluable resource to investigators looking to answer important clinical questions in this field. It is part of the mission of the MBSAQIP to make this data available to all participants to improve the power and reliability of clinical research and further propel innovation in the field of metabolic and bariatric surgery. The data files are made available in a delimited text, SAS, and SPSS file type.
The 2023 dataset will be the fourth PUF consisting of data from the new registry (est. 1/1/2020). Due to significant updates, please refer to the latest corresponding reference documents for this PUF as they may not align with historical references.
The 2023 MBSAQIP PUF contains 217,952 cases submitted from 961 MBSAQIP-participating centers.
The PUF User Guide is designed to accompany the Participant Use Data File and is available for download. The sections contained herein will provide the user with information on how to request the PUF, contents of the data files, data collection background, data limitations, and answers to frequently asked questions.
