Sounds like you have a lot of experience!
How about adding ACLS, PALS, NRP, TNCC, ENPC to your list of certificates?
Since you've had past ED experience, you could take the CEN to show that you still have the knowledge.
I know this might cost quite a penny, but you could get the essential certificates, submit your applications to hospitals, and see what happens.
I've kept myself updated with ACLS, PALS, NRP, TNCC, & ENPC, just so I stay up-to-date with the skills. Its stuff you are familiar with already
Update us on how it goes! It could help some of us (with years of experience in acute care and home care) transition back to the hospital.
