Research Patient Data Registry (RPDR)

The Research Patient Data Registry (RPDR) is the central link to the Partners clinical data registry. The RPDR’s online query tool provides users with aggregate numbers of patients that meet user-defined characteristics and criteria such as diagnoses, procedures, medications and/or laboratory results.

The Data Request Wizards allow the user to ask for more detailed medical record information on the identified patient population. This process requires an approved IRB protocol. Contact the DCR with questions.

Research Study Volunteer Program (RSVP for Health)

The Research Study Volunteer Program, RSVP for Health, is a registry of individuals interested in clinical research at MGH and Brigham and Women’s Hospital. RSVP for Health users are able to search the database by disease area, age, race, gender, and ethnicity.

Once you've identified the population you'd like to contact, RSVP for Health sends potential volunteers an email containing the IRB-approved study announcement and prepares letters for those who wish to be contacted through US mail.

The identity of potential volunteers is maintained until they choose to contact you. Find more information and apply for an RSVP account.

Shared Health Research Information Network (SHRINE)

The Shared Health Research Information Network (SHRINE) helps Harvard-affiliated researchers compile large groups of well-characterized patients.

Eligible investigators may use the SHRINE web-based query tool to determine the aggregate total number of patients at participating hospitals who meet a given set of inclusion and exclusion criteria (currently demographics, diagnoses, medications, and selected laboratory values).
