Instructions for Accessing AHSQC Data for Research

  • Data collected for quality improvement purposes in the AHSQC can be used for research in certain circumstances​
  • Any use of AHSQC data for research purposes should involve either your local or private Institutional Review Board (IRB) 
  • AHSQC surgeons and individually approved personnel can access your own patients’ data any time for research by direct download from the AHSQC user interface. Please be aware that downloading information in this manner may include protected health information depending on your selections for export. Please follow your local institutional or practice policies regarding proper handling of protected health information.
  • AHSQC surgeons can request summary analyzed research data for all AHSQC patients by completing the appropriate form below. The request is approved by the AHSQC Data Use and Publications Committee and analysis performed in partnership between the requesting surgeon or group and the AHSQC Data Coordination Center. Currently this service is provided free of charge to AHSQC surgeons in good standing.
  • Members of industry and researchers can also request summary analyzed research data by completing the appropriate form below. Individual fees may apply.


AHSQC Participating Surgeon and Institution Request for Data

AHSQC surgeons in good standing by being active, participating members of the AHSQC are entitled to have access to the collaborative-wide AHSQC data. For more information on how to request data and the requirements, please click here for the FAQS: Use of AHSQC Registry Data by AHSQC Surgeons. To view other data requests that have been submitted and approved, please scroll to the bottom of this page. To submit a data request, please click the button below.
