Yes — realistically, some kind of healthcare background. The employers in this directory sponsor people whose experience they can use: clinical work, HIM/medical records, billing and revenue cycle, patient access/registration, or IT and support roles inside healthcare. If you have none of that yet, the directory still shows you the map, but your first move is a foot-in-the-door healthcare role (patient access, help desk, super-user, go-live support) — the chapters flag those entry points. It will not make someone with zero healthcare experience an analyst candidate overnight.
