+12 hours a week extra is a stretch. No one I know puts in 52-56 hours a week.
I've made the move from staff, to lead, and soon to be manager.
But its not 12 hours a week extra in actual work. It's more or less, checking your work phone for emails, answering 10 second phone calls from staff, etc. You're definitely wired in more. I would say, maybe 5 extra hours a week.
I certainly did put in that time exclusively on residency affairs, then again, it wasn't for two, it was for eight divided into 6 first and 2 second years which included dealing with ASHP, VA's Office of Academic Affiliations, and the local University. Much of this revolved around dealing with the accreditation/regulatory paperwork, the management of relations between the educational entities, and the incident management. I spent very defined levels of time with the residents, but the regulatory aspects were a black hole timewise. The per unit addition of another resident is not that big a deal, but the paperwork and personality/HR struggles really can get complex at times. My successor to the position averages 60 hours a week just for the residents side. Just to say from the VA's POV, OAA mandates that should a residency get funded, the RPD is at least 50% placed on it if not more and VA's HR usually understates the commitment. I can't see how you managed to do this in only 5-6 hours if you have to deal with the bureaucracy, I know I couldn't get through AAHRPP accreditation paperwork for clinical education in less than 120 hours per re-up period (5 years now), and I just finished one for a site from a burnt out RPD.
Now, some of that time is comingled with dealing with the IRB/ORD and other university affairs, but if I were purely an RPD, it's no less than a 20 hour assignment at the best of times, and can be a 50-60 hour assignment during the peak periods (Indoc, Presentation Week, Etc.).
Much of it has to do with the bureaucratic structure of your hospital, your academic affiliations, and the relationship with ASHP. You're always working on some project or other on top of making sure the residents get their checklists done and being a mother/father, drinking buddy, psychologist, professor, and supervisor of them.
But if you have a low-key place without the institutional entanglements, yeah, I'd say it'd be averages at most 6 hours a week during normal times. But performance times, I'd be lucky to get out with 20 over.
I'm very happy with my outcomes (and so does everyone else who hires them), I have four VACO, two tenured faculty, and six HHS White Oak staff out of 14 residents, but my major regret is always that I spent more time on the stupid arrangements than actually with them. Then again, I do view the majority of pharmacy residents and their training to be substandard and a waste of everyone's year, but what's new in this profession?
My response is different to
@awval999 but I have a feeling if we switched places that it would be more or less the same answers. Almost all of this is environmental, the actual precepting of residents has fairly standard limits like prescriptions, but for me, it's all in the administrative burdens that guarantee me never to take that position again. You want me to train or babysit a resident, great, I'm in. But don't throw me into a management headache where the downside is endless.
