Van Leer PE, Lavine EK, Rabrich JS, et al. Resident Supervision and Patient Safety: Do Different Levels of Resident Supervision Affect the Rate of Morbidity and Mortality Cases? J Emerg Med. 2015;49(6):944-8. doi:10.1016/j.jemermed.2015.05.033.

Furthermore, there was no evidence of a "July Effect," as the number of morbidity and mortality cases did not change in the beginning of the academic year.
