Sleep Studies

A sleep study, also known as a polysomnogram, is a non-invasive procedure typically requiring a one to two night stay in a sleep facility.

Research seems to suggest a potential effect on the quality of patient care as a result of such sleep deprivation.A 2011 study that took place in Korea scored a number of residents and interns on sleep deprivation. Nearly 71% of participants were...
