GIQuIC Research Overview


Since 2010, GIQuIC has set the standard in the collection and reporting of quality measures in the practice of gastrointestinal endoscopy. This robust dataset is an invaluable resource for practice benchmarking and further provides an excellent opportunity for those interested in gastroenterology research.

GIQuIC registry data are contributed from endoscopy units in various practice settings across the United States. Data enters the registry via two methods: direct data entry or, more commonly, upload from an endowriter. For the purpose of research, GIQuIC registry data undergoes a de-identification process and is transferred to the Research Data Warehouse. This separate database is stored on a different secure server from the registry data and can only be accessed by GIQuIC staff.

The Research Data warehouse contains de-identified information on sites, providers, and patients and procedures that allows investigators to address complex and varied research questions. For an overview of data included in the registry, please refer to the colonoscopy and EGD data collection forms.

The GIQuIC Research Committee carefully reviews all project proposals, evaluating the project’s feasibility, novelty and potential impact. All analyses are completed by GIQuIC’s team of in-house data analysts, who work closely with Project Investigators in order to best address the research question. Most projects are undertaken with the intention of publishing results in a peer-reviewed journal.

GIQuIC Research Policies & Procedures


Our research process generally follows the steps presented below:

  1. Interested investigators contact GIQuIC via research@giquic.org to begin the research process. Upon receipt of the initial query, the investigator will be contacted by a GIQuIC Data Analyst to review any preliminary questions and to discuss the feasibility of the proposed project.

    The GIQuIC Data Analyst will furnish the investigator with a research proposal form. This form includes questions regarding the project background/significance, research question and/or hypothesis, and specific aims. Proposals may also include an overview of methodology and statistical analyses. If applicable, a Conflict of Interest form may be required.
  1. Upon receipt of a project proposal form, a GIQuIC Data Analyst will contact the investigators to inform them that the submission has been received and, if necessary, to review any items that require immediate clarification. If necessary, preliminary edits to the proposal may be suggested or requested.
  1. Refined proposals will be presented to the GIQuIC Research Committee on a biannual basis. Among other considerations, proposals are evaluated for feasibility, novelty, potential impact/importance to the GI community, and overlap with other GIQuIC research projects. Only a limited number of research projects will be considered for approval and approved at one time.
  1. Approval will be granted to proposals deemed by the Research Committee to be a strong fit for the Research Data Warehouse’s capabilities. If approved, a scope of work will be drafted and sent to the investigators for their review. This scope of work will include:
    1. Proposal text
    2. Analysis plan, if not included in proposal
    3. Project cost
    4. Contract terms
    5. Signature field for GIQuIC Executive Director and project Principal Investigator.
  1. Once details of the research proposal and scope of work have been agreed upon by both parties, the GIQuIC publication agreement should be signed and submitted to GIQuIC within 14 days.
  1. If applying for grant funding or an abstract deadline, proposals shall be submitted no fewer than 60 days prior to deadline to allow for adequate processing time. GIQuIC will provide a letter of support once the grant submission and the scope of work has been approved.
  1. Upon receipt of the signed scope of work, publication agreement, and a mutually agreed upon payment schedule, a GIQuIC data analyst will initiate the analysis and regularly communicate progress to the Principal Investigator.
  1. If a manuscript has not been submitted to a peer-reviewed journal within 1 year of the receipt of results, the Principal Investigator will transfer his/her rights to the use of those results back to GIQuIC. GIQuIC also reserves the right to prevent a manuscript from consideration for publication if serious concerns are raised regarding the quality or accuracy of the manuscript’s contents.

If at any point during this process it is determined that the GIQuIC Research Data Warehouse is not an appropriate fit for your project, a research staff member will notify you promptly.
If you have any questions about the research process, please see the GIQuIC Research FAQs below or contact GIQuIC Data Analysts here.

Research FAQs


What procedure types are available?
As of October 2019, the Research Data Warehouse contains colonoscopy and EGD data.

Are the data limited to the colonoscopy and EGD quality measures for which GIQuIC reports?
No. The following links will provide you with details on the colonoscopy and EGD data collected. These fields with Protected Health Information (PHI) removed or otherwise transformed constitute the Research Data Warehouse.

Do I need an IRB?
This depends on the nature of your project. Projects that examine GIQuIC data that has been de-identified and transferred to the Research Data Warehouse are exempt from IRB overview as determined by Western IRB. Only GIQuIC staff has access to the Research Data Warehouse. A copy of the Exemption Determination Letter from Western IRB is available upon request. Projects that involve patient and/or provider contact for the collection of information not already included in the research data warehouse will require additional IRB review. This can be covered by Western IRB, or you may choose to use an IRB with which you have an affiliation (e.g. academic institution IRB).

Who performs data extraction, cleaning and analysis? Can I receive a full copy of the dataset?
All data-related tasks (extraction, cleaning, analysis) are performed in-house due to the complex nature of the dataset and the training required to use it. Results are released to investigators only in aggregate form.

Is there a cost associated with GIQuIC research?
Yes. Project costs are determined by the amount of effort required by the GIQuIC staff to complete the proposed work. The effort is based on project complexity, type of statistical analysis and other considerations. The Research staff will work with potential investigators to develop a Scope of Work for project proposals. Funding opportunities are available from numerous sources, including our sponsoring societies the ACG and ASGE.

Does my site need to contribute data to GIQuIC in order to do research?
Being a member of GIQuIC is not a requirement, however we encourage all sites to consider joining the registry, as participation in GIQuIC is one factor that is taken into consideration when determining whether or not the project can be supported.
