Really if you want flexibility with working different area ER, ect then go PA.
If you want to work in the OR go CRNA. There are vast differences between the 2 fields.
As far as job flexiblity as far as hours both are comprable depending on if you work private practice, out pt surgery ect.
As far as number of jobs out there, there are thoussands of CRNA positions as we speak and the need is only increasing daily b/c at present their is an anesthesia provider shortage only expected to get worse over the next decade.
The average CRNA will earn more than the average PA no doubt. In houston new grad CRNA about 130k, New grad PA 75.
Depending on what setting you work in the CRNA will be more autonomous and always has to work under and physician. As a CRNA there are many opportunities to do independent contract work and earn in the 200's easy.
As far as liability the CRNA without a doubt is has way more risks than your average PA. I mean really you push the most potent drugs known to man and then when the pts down you are his life support. Every desicion must be made quick and results are instantaneous. And if you over shoot or the pt doesnt respond as you anticipated its is you that has to fix what you just did. Anesthesia is all about balance, you give this to get this wanted effect but at the same time that wanted effect also has a bad effect so you give something to block that. Its all about balance and you in a split second have to make the descion that for 1 is safe to the pt and for 2 anesthetizes the pt and 3 are able to wake the pt up after anesthesia. This critical thinking you will encounter everyday and all day at work. Though they do have many great PA's out there. Believe me I have worked with some in the ICU. But largely besides those in ICU and ER maybe most PA's arent making these crucial descision day in and day out.
SO my advice. Go the CRNA route. To me the work is may more mentally demanding which I like, at every second of your work day there is a pretty strong chance something drastic may happen and you have to know why, what and how to fix it and then how to fix your fix b/c it caused something else you dont want. Also the pay is better and the opportunities for getting out from the MD's wing and not having to constantly have some superior sign off on things that you know were right or have some one always tell you what to do. I mean it really gets frustrating when you know you made the right call but for your entire career you have to get someone to verify correctness and sign off.
As far the AA yes they get paid well but if you want to compare CRNA job availabilites and AA's then there is merely no comparision.
Go to
www.gaswork.com
it is the largest anesthesia job website out there and check out the CRNA opportunities. Just looked and there are about 1600 jobs list in the US and thats just on that site alone. There are about 30 AA jobs on this site advertised for .
So really your desicion comes down to what you wanna do, salary, and what you desires are. CRNA is demading and mentally challenging day in and day out. I love it and could not have entered a better profession in my opinion.
We do appealing and challenging work and for the most part are the highest paid midlevel practioner when comparing salaries to PA's, NP's, even optometrist many times.
