NAHMS is committed to protecting the confidentiality of the information provided by participants in NAHMS studies. Only those collecting the data know the identity of respondents. No name or contact information is associated with individual data, and no data are reported in a way that could reveal the identity of a participant, as data are presented only in an aggregate manner.

To further protect respondents’ information, NAHMS applied for, and in March 2012 received, recognition as a statistical unit under the Confidential Information Protection and Statistical Efficiency Act (CIPSEA). Enacted in 2002, CIPSEA provides a way for Federal agencies to collect statistical information and protect its confidentiality using the force of law.

The specific data protections given to a NAHMS study participant's data is described in detail in informed consent forms administered during the study. Additional information regarding NAHMS' CIPSEA status as well as annual CIPSEA reports are available below.
