Official title

Exploring the Impact of Sleep Deprivation and Caffeine on Operationally Relevant Complex Cognitive Processes in Medical Professionals

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

While the negative impact of sleep deprivation on cognitive processing and the partial reversal of this phenomenon by caffeine are well known, the types of cognitive processing previously studied have been limited to simple, straight-forward laboratory tasks. It is unclear how sleep deprivation and caffeine affect performance on operationally relevant complex cognitive tasks, like those encountered by working professionals such as doctors. This study aims to uncover how sleep deprivation and caffeine impact two types of clinical reasoning processes encountered by physicians on a daily basis. Previous work from members of our team investigated diagnostic reasoning in medical professionals and discovered that brain activation in executive processing areas was modulated by self-reported sleepiness and burnout and level of expertise (Durning, Costanzo, et al., 2013; Durning et al., 2014, 2015). The current study aims to expand upon those findings by also investigating a potentially more complex type of clinical reasoning, i.e. therapeutic reasoning, and directly manipulating sleep and caffeine use in a controlled sleep laboratory. Medical students, residents, and board-certified physicians will undergo thirty-seven hours of sleep deprivation and ten hours of sleep recovery in the sleep laboratory. During two FMRI scan sessions we will present high-quality validated multiple-choice questions on common patient situations in internal medicine to participants to explore brain activity during therapeutic reasoning compared with diagnostic reasoning. One FMRI scan will occur following a night of sleep deprivation, and another scan will occur following a night of recovery sleep. Additionally, half of the participants will receive caffeine gum during the sleep deprivation period, while the other half will receive placebo gum. This design will allow us to study the effect of sleep deprivation and caffeine on the neural correlates of diagnostic and therapeutic reasoning and performance in general.
