Welcome to the CESQIP Aggregate Data Use Portal. CESQIP participants are invited to submit data use proposals to query the aggregate data in one of CESQIP’s 6 organ specific modules. The American Association of Endocrine Surgeons CESQIP Committee, which oversees the aggregate data analysis program, has worked diligently to create a fair, transparent and consistent process for CESQIP data analysis. At present, the CESQIP aggregate data use program is open to CESQIP participants in good standing; proposals from non-CESQIP investigators will not be accepted. Please refer to the Program Guide for detailed instructions on how to submit a data use proposal.
