During medical training, residents experience sleep disorders due to extended work hours, shift work and interrupted sleep. These alterations lead to a reduction in mental and physical performance capability which can affect resident?s safety and well-being, and have potentially adverse implications on patient care. For example, there are many studies that have reported an increase in medical resident?s errors working after an extended shift compared to after a night of sleep.The aim of this project was to study the existence of temperature rhythms alterations in medical residents and its relationship with the number of incidents that happened to the professional at the hospital. We analysed these variables in a group of 31 medical residents from 5 different hospitals of Buenos Aires city. The temperature rhythm was recorded during 7 days and then we conducted a cosinor analysis to obtain the amplitude and percentage of variance of the oscillation. We have found that the residents who reported one or more incidents during the study week, had a lower amplitude (Mean ± SEM: 0,55 ± 0,13 vs 0,90 ± 0,09; p=0.023) and percentage of variance (Mean ± SEM: 14,64 ± 5,03 vs 26,22 ± 3,34; p=0.021) of the temperature rhythm compared to the ones who didn´t report any incident. These results suggest the development of new methods to monitor circadian misalignment due to extended shifts and sleep disorders in residents, to prevent future incidents and accidents in health care facilities.
