Grant: Planning and Dissemination Grant - Institute Community Support

Sleep can affect many aspects of health, and normal sleep parameters change across key demographic variables such as age and sex. In our 2019 manuscript published in The Lancet Respiratory Medicine, we established normal values for sleep studies in healthy participants. Based on this data, we created an interactive tool for clinicians, researchers, and the general public to use: psgnorms.com. Users can enter age and sex data and receive an accurate range of values for sleep study (polysomnography) parameters of interest. Since the creation of this tool, we have also established normal values for the Multiple Sleep Latency Test, a daytime sleep test used to test for narcolepsy and related conditions. We plan to incorporate these results into the online calculator, so you can input age and sex information, and receive an output of normal Multiple Sleep Latency Test values. We have also conducted a study examining the relationship between sleep parameters and clinical outcomes. We performed an analysis that identified clusters of distinct sleep subgroups, including 'Mild', 'Poor Sleep,' 'Severe Obstructive Sleep Apnea,' 'Hypoxemia,' and 'Periodic Limb Movements'. A user can input their values from a sleep study and receive an output that indicates which subgroup they are in. This calculator is very useful for easily identifying a patient's sleep subtype and their associated health risks. The overall objective of this dissemination project would be to maintain psgnorms.com and update it to include the normal Multiple Sleep Latency Test values and the sleep subgroup calculator. We anticipate that this interactive tool will be widely disseminated and frequently accessed by clinicians and researchers, as well as the general public.
