What is the point of limiting the scope of discussion to a single visit per year? Am I missing some context from the article that makes this relevant to things like the expense of follow-up visits to confirm/treat complex diagnoses such as secondary hypoaldosteronism, discussed in the article? In my case, I have multiple conditions that require expensive monthly or annual visits, which I’ve severely lapsed on.
