Data Sharing

IPD Sharing
Will share

The plan will comply with the NIH HEAL Initiative ClinicalTrials.govSM Public Access and Data Sharing Policy, NIH Data Sharing Policy, NIH Policy on Dissemination of NIH-Funded Clinical Trial Information, and NIH Clinical Trial Registration and Results Information Submission rule. All IPD will be in a repository supported by NIDA, the NAHDAP, following NIH requirements for sharing data via creation of public-use data sets. Data will be de-identified/masked to minimize risk of potential re-identification to participants. This may include modification of the original data to reduce risk of re-identification of participants. A structured process will evaluate the risk of re-identification based on guidance documents from the US DHHS, HIPAA, and quantitative evaluation of the data using statistical methods. Potential revisions to the data to prepare them for NAHDAP include omission of variables, collapsing of categories of a variable, or other coarsening of specific participants' values.

Shared Documents
STUDY PROTOCOL, SAP
Time Frame
HEAL Prevention Cooperative (HPC) data is anticipated to be archived in May 2026.
Access Criteria
The HEAL Coordinating Center will provide HPC data as well as supporting documentation for the HPC Common Measures as well as data that are uniquely collected as part of each HPC Research Project. The NAHDAP repository disseminates data to users based on its Access Policy Framework. Researchers who are not part of the HCP will be able to download HPC datasets and analyze them on their own computers. Access to data requires submission of username, institution, and analytic purpose and aim. There is no formal approval process initially planned by NIDA. Data users are expected to adhere to norms for responsible use.
