Patients Know Best supports a privacy label for each data point and restricts access to the data point to those who have permission to view the privacy label. This allows the patient to restrict sharing some data to some people.
PKB supports four labels: general, sexual, mental and social care data. For example, a sexual health team may label all data it sends to PKB as "sexual" so that only people the patient trusts with access to the "sexual" records can see these data.
