Guidelines for External Collaborators

The Nurses’ Health Studies (NHS and NHSII) have a proud history of successful collaborations with investigators external to the Brigham and Women’s Hospital and Harvard School of Public Health community.  We welcome new collaborations and strive to make their establishment as simple and transparent as possible while also maximizing the scientific yield.  To this effect, we have developed the following policies and guidelines for external access to archived data and biospecimens with the approval of the Nurses’ Health Study Advisory Board and in compliance with our NIH approved plan for data-sharing.
