Solutions
The patient is not accustomed to having a choice in their health as the insurance market has dictated that for decades. There are two obstacles to overcome to provide real choice to any consumer.
- The patient must learn that they have a choice. Even though the 21st Century Cares Act gives them choice, it is not enforceable until October 2020 since extended to October 2021..
- The patient must have easy access to clear data to make a choice. In particular the effectiveness and out-of-pocket cost of any procedure or medicine. This will probably be decided in a hit-or-miss approach unless some real user research can be done.
- The computer industry has learned that security cannot be a choice and has taken the responsibility to assure that their software does not expose the user to exploits that are launched regularly from any site that has access to the internet.
- If the patient is to have a choice about the release of their protected health information (PHI), they must be able to rely on the software that is installed on the healthcare providers computers as well as any software that they use on their own computers.
- To enable real patient choice, the healthcare community must create a trust registry of web sites and applications that are to be trusted with patient healthcare information (covered HIPAA entities). In other words, enabling patient choice on access to their data, the patient must be limited to the use of secure sites and applications that can be trusted to maintain the security of that information.
- The healthcare community must prevent any sites or apps that are not in the US Healthcare Assurance Registry from downloading patient data.
- The healthcare community should prevent any user app from uploading data is not from a trusted site or app into the patient's EHR.
- To be sure that patient concerns are met, a Trustworthy Healthcare Ecosystem must exist to be able to strongly identify these actors:
- The Patient must be able to prove that they are the owner (or Guardian of the owner) of the PHI.
- The Patient app must be trusted to faithfully present the patient authentication and protect PHI that the patient downloads.
- The source of the data must be trusted to show the provenance of the data. That is to show that the data is legitimate and accurate.
- If the patient chooses to share PHI, they must be able to assure that the recipient of the data will treat the data with the full protections of HIPAA.
- The question about PHI that is released to non-HIPAA covered entities has not yet been addressed. But is it clear that the patient needs to understand the implications and risks of such a release before it happens.
Expected Types of Access Methods
For users with some computer literacy:
- Browser on a personal or public device
- User portable device with browser and local storage for continued connectivity.
- User agent running the cloud that can be accessed with any browser
- User agent in a native app on a user owned device using traditional sources of an identifier
- User agent in a native app on a portable user owned device with a self-issued identifier
Consent and Notification
- The current medical practice is for the user to be given a form at the physician’s office that give consent to keep records in a patient’s EHR is a health data repository (called a data controller in the GDPR) for the physician, the patient and other providers. This is typically extended to referrals where the patient is giving consent to send medical records that are relevant to the referral. No change is proposed here.
- Once the records are at the referred EHR, the Cares Act gives the patient the right to see and acquire PHI from that source as well. Clearly it is important for remote access by the user to exercise this right, but only under careful identity proofing with patient credentials which are protected to AAL2 in NIST 800-63-3B,
- Patient Consent that is provided on any such protected remote access must be recorded and acknowledged to the patient, preferable with a receipt that is similar in concept to the one that the patient receives in the office. (Also known as the Break-the-Glass scenario.)
- Users must be able to determine which information will be released to other locations which will be conditioned on the purpose of that access
- Users will always be notified of changes to access list, medicines and other issues related to their health and security breaches
- More information is included on the wiki page Patient Consent.
Other functionality that a device app could supply
- The app could be used by a medical record source to determine which categories of medical records the patient wants to share with other HIPAA covered entities.
- The app could respond to requests by an EHR for current information, with the data is held by the user, or by forwarding the request to the source EHR.
- The patient or legal system can enable guardians to use the app for access or update of patient data.
