Indication of inappropriate use

If you believe that your content has been improperly used on a platform or that another person has violated these Terms of Use, please contact us.

Anonymity of cases / images and other patient data

It is a requirement of the Terms of Use that all patient cases uploaded to the Platform by users be anonymized so that the identity of each patient to whom the content contained in the case relates (e.g. x-rays and case notes) is not reasonably identifiable. If you notice a case in which you believe that you (as a patient) or another person is identifiable, please contact us promptly at [email protected] and we will investigate the case and provide you with a prompt reply.

Information that should NOT be displayed in patient cases uploaded to a platform (based on HIPAA guidelines) includes, but is not limited to:

  • Name
  • Initials
  • Date of birth
  • Address, including full or partial postal code
  • Telephone or fax numbers or contact information
  • E-mail addresses, chat names etc.
  • Unique identification numbers (e.g. UR, MRN, HID etc ..)
  • Vehicle identifiers
  • Medical product indicator (e.g. serial numbers)
  • Web or Internet protocol addresses containing a link to the patient
  • Biometric data
  • Face photography or comparable image
  • Names of relatives
  • Date of study

If, for one reason or another, a case is so clear that a person can be identified from the images alone, it should not be uploaded. This means that a case that appears in the media, for example, or has particularly rare symptoms, is usually not suitable for uploading. Similarly, the text information attached to the text should not contain any identifying information and should not contain any other unnecessary information that could help identify a patient.

Note: Our Privacy Policy does not override individual institutional policies, and users should ensure that they use images within their local policies.

We take the privacy of our patients very seriously and violate our privacy policies and terms of use. If you upload a case that contains patient information or otherwise identifies a person, your case will be deleted from the platforms immediately upon learning of the existence of the platform, and we may take action against you in accordance with the Terms of Use.
