I currently work for Optum... You may not recognize the company but in actuality it is a division of United Healthcare. I work in the Welcome Home/Impact Unit. I am in Texas. My job is to contact newly discharged patients and assist them with resources and help them to utilize their doctors, medications etc to stay out of the hospital.. Optum has a number of divisions: Inpatient Care Advocates- RN's who keep track of inpatients, assist with discharge planning, transfers to alternative living areas, etc. This area is where I get my list of patients from. Another area is the Predictive Model unit. This unit cold calls individuals who are showing a high dollar expense. They also assist the individual in following dr's orders, checking medications etc. Another area is Case Management: obviously when I find a patient that needs more attention then my job allows, they are referred to CM. As for Nurseline, it is a unit that takes incoming calls from individuals who have questions about medications, procedures etc or it could be a new Mom who has a sick baby and doesn't know what to do... I have several friends that are in Nurseline. There are a lot of AARP calls. It does require 8-10 hrs of sitting with small breaks and a lunch break. If you can't sit for extended periods of time, it is not for you. The advantage is you can work from home, but the requirements for connection are very rigid. And you do have to work every other weekend or on some schedules you get either Sat or Sun off each week. The shifts are pre-set... but there is usually one that fits your needs. You are expected to meet time restraints, and that can be difficult if you get someone that can not stay on subject... As far as applying, what can they say but no.... and you wouldn't be any worse off. Go for it.
