What Does A Hospital Registrar Do?

As a registrar in our facility I am responsible for gathering all health information as well as personal and financial information of every single patient that enters the buildings. We are per-say "the gate keepers" of mainly the emergency room and above floors.

I am guessing that this is a USA question because in the UK a Registrar is a grade of qualified doctor, just 2 steps below Consultant. Another instance where an indication of country of origin of Q and A would be useful.

A registrar basically signs in patients.

The hospital registrar is responsible for a number of functions like;
- Performing all the registration functions at the information desk as well as inpatient and outpatient registration
- Initiate certification and obtain authorization for providing services.
- Verify eligibility for insurance certification.
- collect all co-payments.
