Physicians from end-of-life specialties not only did not have increased rates of burnout but they were also more likely to report a sense of calling in caring for the dying.

After categorizing allopathic medical schools into four groups based on SMS rankings, we found that medical students who attended allopathic medical schools from the two highest SMS ranking groups were more likely to report scores reflecting strong vocational identities-odds ratio [OR] = 2.9, 95% confidence interval (CI) [1.8, 4.7] and OR = 2.5, 95% CI [1.6, 4.0], respectively. In contrast, we did not find any associations between students from allopathic medical schools with high USNWR rankings and likelihood of reporting scores reflecting strong vocational identities. Insights: Social mission scores for allopathic medical schools may potentially serve as predictors of professional and vocational identity development. Further research is needed to better understand these findings, as this is one of the first studies both to examine allopathic medical students' sense of vocational identity and to explore the use of SMS rankings as predictors of medical students' professional development.
