Aimed at clinicians, hospital governance personnel and other healthcare stakeholders including patients, the petition states:
We, the undersigned, believe in transparency, accuracy, and accountability in scientific research, especially in matters related to healthcare.
We believe contractual nondisclosure clauses  that prohibit or restrain unfettered disclosure and dissemination of information about healthcare information technology problems related to bugs, design defects, suboptimal user interfaces, other factors that can adversely affect care, and the adverse events and near accidents these problems cause, are unethical.
We believe that patients and clinicians have a right to knowledge of healthcare information technology problems and defects that can distract clinicians and/or reduce clinician effectiveness and productivity. We also believe that hospital governance personnel have the fiduciary responsibility as well as obligation under Joint Commission safety standards to protect patients, clinicians and others working within and for their organizations from the potential consequences of healthcare information technology problems .
We believe that only through transparency about healthcare information technology can medical ethics be maintained, the rights of patients to the best possible care be protected and medical science advanced.
Therefore, we call for such clauses to be refused by governance bodies, vendors of healthcare information technology to refrain from including such clauses in their contracts, and the U.S. Congress to prohibit nondisclosure clauses related to medical devices and healthcare information technology.
Furthermore, retaliatory actions against those who in good faith report such matters or incidents should be prohibited.

Addendum: as an example of the problems these nondisclosure clauses can create, see my post "We are unable to share documents relating to problematic EHR's as our contract with Cerner includes a confidentiality clause."
