When job burnout was first described by Christina Maslach et al, it was specific to caring professionals. Eventually, it was found that it can occur in all occupations and across all demographics. Physician and nurse burnout has been the hot topic the last few years, though a recent meta-analysis pointed out that there’s little that can be concluded about physician burnout because of the level of variation in definition and measurement (a lot of people disagree with this).
Studies have found that pervasiveness of Electronic Medical Records plays a big role in physician burnout. This makes sense, as it can be connected to several of the known burnout antecedents, especially autonomy/control, but also unsatisfactory social interaction and values conflict.
For anyone who wants to quickly get up-to-speed on burnout research, I recommend “Burnout: 35 years of research and practice,” authored by Schaufeli, Maslach, and Leiter.
