In NIH's view, all data should be considered for data sharing.
Data should be made as widely and freely available as possible while safeguarding the privacy of participants, and protecting confidential and proprietary data.
To facilitate data sharing, investigators submitting a research application requesting $500,000 or more of direct costs in any single year to NIH on or after October 1, 2003 are expected to include a plan for sharing final research data for research purposes, or state why data sharing is not possible. investigators collecting data in other countries should familiarize themselves with the policies governing data sharing in the countries in which they plan to work and to address any specific limitations in the data-sharing plan in their application.
The NIH policy on data sharing applies: Policies with respect to data sharing vary across countries. Even if NIH support is sought to transform or link datasets (as opposed to producing a new set of data), the investigator should still include a data-sharing plan in the application.
There are many reasons to share data from NIH-supported studies.
