Are you talking about working as a surveyor/regulator for your state? I did that for several years and really enjoyed it. My specialty is psych, and I was a member of the state team that surveyed all inpatient psych and substance abuse units (freestanding facilities and inpatient units within general hospitals) in the state.
Different states do things different ways (and even different branches within my state agency did things differently), but my
team did annual, routine licensure surveys of all of "our" facilities, and investigated complaints and suspicious deaths. The job involves a lot
of travel -- we were out of town, surveying, pretty much every week; sometimes just for the day, but often away for two, three, or even four days in a week (staying out of town overnight). The remainder of our time consisted of writing up the reports of our surveys and entering our survey findings into the state and Federal survey databases. Every survey, even those where we didn't find anything wrong, required a written report. For surveys in which we found a bunch of deficiencies, the written reports could be 10, 15, 20 or more pages long. The reports are v. technical and precise, and they are public record and have to be able to stand up in court if your findings are challenged by the facility (if a facility formally challenges your findings and the facility and your agency aren't able to resolve the situation themselves, it goes to court and you'll have to testify in court as one of the surveyors involved in that particular survey). The position also involves interacting with everyone from CNAs working on the floors to hospital/facility CEOs and attorneys -- you have to be able to present yourself as competent and professional and come across as credible and reasonable in some v. difficult, challenging situations (sometimes v. painful and emotional situations).
In my experience and opinion, the position requires good clinical experience/background and judgment, good computer skills, and strong
writing skills. A LOT of the job is writing, and the writing has to meet legal and technical standards. There's a lot of bureaucratic tedium and nonsense you have to put up with. Also, the amount of travel isn't for everyone. In my experience in my agency, lots of people took positions in the agency thinking it would be a comparatively "cushy" job, but many people find it just isn't for them (often because they weren't really expecting to be away from home as much as they were, or because of the writing demands). It's a lot harder and more demanding than it looks -- but if you like doing it, it's a great job.
