7807: Validation of Online Cohort of Eosinophilic Gastrointestinal Disorder (EGID) Patients Enrolled in RDCRN CEGIR Contact Registry

Study Summary

The purpose of this study is to determine the accuracy of self-reported Eosinophilic Gastrointestinal Disorders (EGID) information provided by Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR) Contact Registry (CR) participants compared to their physician’s report. Another purpose of this study is to determine the agreement between pathology report confirming EGID diagnosis and both physician and patient report.

For Diseases

  • Eosinophilic Esophagitis (EoE)
  • Eosinophilic Gastritis (EoG)
  • Eosinophilic Enteritis (EoN)
  • Eosinophilic Colitis (EoC)


EGIDs are rare disorders characterized by elevated white blood cells (called eosinophils) in the gastrointestinal tract. The 4 types of EGIDS are: EoE, EoG, EoN and EoC. Patients with EGIDs can join the CEGIR CR where they provide information about their disorder/s. The purpose of this study is to see if the CR participants’ reported disease information matches with the information reported by their physicians.

The research questions are:

  1. Do the CR participants’ self-reported EGID information match their physicians’ reports?
  2. Do the EGID diagnostic pathology reports match both the physician and patient reports?

About this Study

This is a cross sectional survey study involving CEGIR CR participants and their physicians. As of August 16, 2018, there were 1,448 patients in the CEGIR CR. The number of CR participants that are involved in this study will be dependent upon the number that are enrolled in the CR on the study start date. On the study start date, the Data Management and Coordinating Center (DMCC) will send Contact Registrants an introduction email that contains a link to the consent form. If the Contact Registrant provides consent to both participate in the study and for the DMCC to contact their physician, and provides their physician’s contact information, the individual will be directed to complete an online survey, and their physician will be sent an introductory email with a survey link.

The study participant will answer questions on demographics, disease type and activity, medications, medical history and treatment/therapies. The physician will provide relevant information as documented in the patient’s clinical records. Physicians will also be requested to upload their patient’s pathology reports as part of the survey.

Both Contact Registrants and physicians will receive up to 4 e-mails total (1 invitation email and 3 follow-up/reminder e-mails). After 4 e-mails have been sent, the individual will not be contacted about the study again. Both Contact Registrants and physicians will have the option to opt out and to stop being contacted about the study.
