Your duties will depend very much on where you are hired. Some research RNs only do assessments, a few rating scales, and draw blood. Others may do regulatory documents in addition to patient assessment, and a few will do in-patient monitoring.
Lots of documentation, good people skills with generally limited contact, possibly some case-management skills(referring to other care providers, calling scripts, arranging cabs/transportation, collection of outside medical records).
I also do telephone follow-up for clinic patients for QA/QI and some other research projects, and maintain the data on Excel or Access spreadsheets.
If you can offer some idea as to what/where the office is, I can offer more suggestions that may be more tailored with your experience and education in relation to possible needs.
Email me if you want.
