How do I apply for an online "Work remotely from Home" nursing position? I have 39 years active nursing experience. I've worked the majority of that time in the Emergency Dept. I traveled x12 years (critical care/med-surg/telemetry/ICU/ED

LinkedIn has a ton of positions posted for work from home nursing. If you do a job search through their site one of the filters is "remote".

You can also go directly to the company websites, such as United Health Group (UHC, Optum), or Aetna, or BCBS, etc. you’ll need to create a profile and enter your professional info, and upload a resume. With UHG you can do a search for telecommute jobs. Also, a lot of the bigger health systems now let their UR and discharge planning RNs telecommute. Trust me, if you have ever worked on the floor and helped with discharge, you have experience. Insurance companies have a wide range of jobs for nurses, from retrospective review, inpatient case management, prior authorization, appeals, quality assurance, IT, legal, etc.

Look into clinical documental specialist roles (CDS/CDI)! Great money, work from home in many areas, and no weekends/holidays!

Yes. Try LinkedIn and Indeed. Make sure you highlight your ED experience on your resume AND PUT YOUR RESUME ON BOTH PLATFORMS. Use staff that you worked ED with as references, particularly any supervisors and MDs who are willing to assist you.
A lot of work from home positions are for case management and program use review for new patients/recently discharged patients with recently diagnosed chronic illnesses. If you can, take some courses r/t healthcare (staff) management and patient coaching/teaching
Another area to explore is making training videos for staff education; I've seen a couple of postings like that on Indeed recently. Good Luck!!!

First consider your strengths and passions. Is it triage, coaching, education or ?
Kaiser So Cal has options for call center nurses to triage from home. Kaiser Northern California has a different union that fought work from home until a temporary measure during the pandemic.
Wellcoaches can train you well in evidence based coaching for behavior change, then Terra Health looks like a solid organization that employs qualified nurse coaches. I prefer Wellcoaches to any nurse coach program. Their graduates often practice across state lines
