Exhibit 6. Initial Letter to Health Care Practitioners who Self-Query, sent via Email

Dear ,

The U.S. Department of Health and Human Services, Health Resources and Services Administration is conducting a national survey of its eligible users of the NPDB. We periodically conduct surveys of eligible users to ensure we are meeting the needs of those who self-query the NPDB. The results of the evaluation will guide the future strategic directions of the NPDB, and we thank you in advance for your cooperation.

We have contracted with a small business, Cherry Tree Business and Statistical Consulting (Cherry Tree BSC) to conduct the survey. As an eligible user of the NPDB, you have been selected to provide feedback on the effectiveness of NPDB content.

In recognition of your valuable time and critical feedback, Cherry Tree BSC will donate $1 for each completed survey to the Children's Inn, a non-profit providing a home-like environment for children receiving medical treatment at NIH (a maximum donation of $5,000 for all surveys).

The evaluation is conducted on a secure web-site; please click here to complete a web-based survey. If you have questions concerning any aspect of the survey, including confidentiality, please feel free to call Cherry Tree BSC at 423-433-7728 or email at [email protected].

Once again, thank you in advance for your cooperation with this request. Your responses will be confidential and used for research purposes.

Sincerely,

Harnam Singh, PhD.
