Abstract
On-call shifts have been considered an
essential component of medical training since
the twentieth century, as they provide
comprehensive experience within a clinical
environment.¹ In Mexico, after completing six
to seven years of professional education,
including undergraduate internship, many
physicians choose to pursue a specialty.
According to the parameters established by
NOM-001-SSA-2023,² work schedules may
extend up to 80 hours per week with on-call
shifts twice a week. However, these limits are
often not respected, and the number of hours
spent in the hospital by residents—or even
undergraduate medical interns—may be
significantly prolonged.
