Despite increased attention on diversity in medicine and healthcare, heterogeneity in simulation technology has been slow to follow suit. In a nonsystematic review of simulation technology available in 2018 with respect to skin tone, age and sex, we found limited diversity in these offerings, suggesting limitations to educators' abilities to represent the full array of patients, conditions, and scenarios encountered in medicine and training. We highlight these limitations and propose basic strategies by which educators can increase awareness of and incorporate diversity into the simulation arena.
