Is it common for Anesthesia Interventional Pain docs to also work 1-2 days in the OR?

Is this possible/common? You'd think it'd be a good idea for anesthesiologists to keep their OR skills by working a shift or two per week in case business goes bad with their pain practice. Also is the future of interventional pain bleak and/or saturated? I tried to search some threads regarding this topic and only found answers during the Obama era when every one was scared about obamacare and eventual push toward single payer. I think much of those concerns have been alleviated even if... Is it common for Anesthesia Interventional Pain docs to also work 1-2 days in the OR?
