Sure, just take on less patients. That makes sense. No need to give 3 shakes about the under-served. What a myopic worldview.
I'm a family medicine resident. When I'm done, I plan on working in a community health center. It is pretty much a guarantee that I'll be working with the underserved in some capacity for the next few years, and, hopefully, for the rest of my career.
I don't know if I could work in an outpatient clinic if it meant seeing patients for 65 hours a week, to be honest. 65 hours a week is 5 days a week, 13 hours a day. I guess I could do it if I had a PA to see all non-urgent sick visits (colds, splinters, coughs, etc.), as well as to do paperwork (physical exam forms, drivers license physicals, FMLA forms, prior authorizations). Also, if I were in a clinic where I were allowed to refuse to see any drug seekers that argued, threatened, or became violent, as well as any patient who pulled out the "lawsuit" word as a threat. And, also, if charting were kept to a minimum. Then, in that case, maybe.
Otherwise, 65 hours a week of seeing patients, one every 15 minutes - all the arguing, paperwork, red tape, headaches....I think I'd burn out after 5 years or so. I mean, don't get me wrong, I actually like clinic and primary care....but not enough to do it all the time.
So I can't really blame people who want to work less or go part time. I figure that they have their reasons, and who am I to say if they're good reasons or not?
