The average size of electronic medical records grows each year. Some of the drivers of this growth are the increased utilization of EMR systems, scanning of paper records, and improved access to health information exchanges. As a consequence, patients need more sophisticated tools to adequately express their privacy preferences. When your medical record contains only a few x-rays and is only ever shared between your family doctor and your radiologist, a simple “yes” or “no” to data sharing may be sufficient to express your privacy preferences. But if your record contains family and social history, photos of skin conditions, STD panels, genetic information, and psychiatric evaluations and different parts of that record need to be accessed by a small army of physicians, surgeons, therapists and dental hygienists, you might need a more detailed method of defining your privacy preferences than “yes” or “no”.
In light of this growing need for more sophisticated consent documents, the IHE IT Infrastructure Domain decided to define a new profile, IHE APPC (Advanced Patient Privacy Consents), that compliments BPPC by addressing additional use cases. Development of this profile started in late 2015 and was supported by an international group of stakeholders. The profile was published as a new “Supplement for Trial Implementation” in August 2016.
We hope to empower both healthcare providers AND patients with the IHE APPC profile. Without a flexible language for defining access control rules for each project, vendors will force the same one-size-fits-all access control approach onto all healthcare providers, regardless of their specific needs. Using the IHE APPC profile, healthcare providers will be able to define an access control approach that fits their processes and their patient collective. E.g. pediatric oncology patients need their data available for regular follow-ups for a long time, whereas a surgery ER patient’s data could potentially be more ephemeral.
Patients will benefit by having a less monolithic approach to privacy preferences. While it is unrealistic that there will be completely different rules for each patient, there is a finite list of common customizations that can easily be implemented in an enforcement system based on IHE APPC. A common type of patient-specific customization is to blacklist specific providers (colleagues, relatives, former lovers, …) to deny them access to your patient record. Another common customization is hiding specific documents (e.g. drug testing results, psychiatric evaluations).
“The advantage for patients is the greater consideration of their individual needs.”
Of course in the grand scheme of things, technology, standards and products are just minor elements in arriving at a patient-friendly and efficient privacy scheme. Privacy laws and regulations, healthcare provider’s competitive landscape and association politics, liability laws, etc. usually have a greater impact on what the actual privacy choices for patients are. But when it is time to establish an agreed upon set of privacy policies in real world IT systems, it is important to have specifications like IHE APPC ready to enable an easy and cost-efficient implementation.
