Patients dealing with recurrent infections are stuck choosing between generic symptom apps and nothing at all — so they default to memory, and memory fails.
On your end as a physician, there's no way to see the bigger picture either. Even with careful notes, you're working from one chart at a time, with no visibility into how these infections are behaving across your patients as a group.
UTI history shouldn't have to live in your memory, your notes, and your patient's best guess.
