Of course, first of all, it's a recall registry, but you can implement PROMs—patient reports of outcome measurements—on the questionnaires that patients have. For instance, in the Netherlands, they are currently doing that. They are registering all kinds of complaints from patients to see how often breast implant illness occurs, how often autoimmune diseases occur and how often ALCL occurs.
Those are things that can be implemented in the registry. It needs extra effort, a lot of work, but it can be done and it should be done.
