Cover letter advice for ER job- switching specialties- Please help!

[ivyleaf]

I am working on a cover letter to apply for an ED position at a facility where I previously worked per diem. All of my experience is in psych (I kind of fell into it after graduation, long story) and I really want to make the switch to ER.

I am trying to show how I have experience assessing clients and working autonomously. I am debating highlighting that in my current position (Community mental health outreach/health education) I work in an outpatient setting without a doctor/NP/medical provider. In addition, I work in a freestanding psych crisis unit where there is only 1 nurse per shift and no doctors (except for on call of course, and there are only 6 clts).

Should I highlight these, or does this put me in a negative light, as it also highlights my lack of acute care experience (I have worked inpt psychiatry, did an ER rotation in school, volunteered at an ER way back when, and worked as a CNA in med surg)?

Any other CL advice would also be appreciated!!

Thanks : )
