Abstract Details

Where do patients get diagnosed with idiopathic Rapid Eye Movement Behavior Disorder?
Sleep

Enrolling participants with Idiopathic Rapid Eye Movement Sleep Behavioral Disorder (iRBD) into synuclienopathy trials is an important clinical research priority. 
Little is known about the breadth of clinical settings where diagnoses of iRBD are initially made.
We conducted a retrospective cohort study using the electronic medical record system at the University of Michigan to identify patients age 60 or older with new diagnoses of iRBD between 1/1/2015 and 12/31/2020. We focused our search specifically on patients receiving primary care at UM so that we might use the UM EMR to capture the full scope of their multispeciality care interactions and diagnoses in this integrated care health care system. We used ICD-9/10 diagnosis codes to identify the time of initial clinical diagnosis.
62/105 (59.0%) of diagnoses were made by a Sleep specialist, 9 (8.6%) by Neurology, and 30 (29.5%) by generalists or primary care (29.5%) providers. 67/105 (63.8%) of diagnoses were made in the context of having available PSG results while the remainder were made on the grounds of clinical symptoms alone. A clinician review of the prognostic implications of iRBD was documented in 40/105 (38.1%) encounter notes and was more likely to occur in Sleep clinic settings (chi-square:12.74, p<0.001) than in other contexts.
Initial iRBD diagnoses occur in varied clinical settings in an integrated health care system and are commonly made without a confirmatory polysomnogram. Documented prognostic counselling is seen most often in Sleep medicine clinics. Synucleiopathy prevention trials may be best designed around a sleep-clinic-focused recruitment approach.
