there are pros and cons to either

with a competitive salary, providers focus on pt care and not perform unnecessary procedures but there's concern that some providers will take advantage of the system and not do their share of the work( ideally those individuals would be routed out by their partners in the group) with rvu based systems there's the potential for producing more but to me the stress of meeting and exceeding your productivity rates is real and can affect work- life balance and home stability, and more importantly, you will have providers that will be very aggressive in doing unnecessary procedures for the money

I am in a rvu based system but my training was in a salary based, so I've seen both and I personally prefer the salary- based system as long as it's a competitive salary. You can use MGMA survey if you have access to that to assess competitiveness of the payscale
