The cohort consists of two overlapping groups of patients. First, we are including patients of the Chase Family Movement Disorders Center (CFMDC), an ambulatory program affiliated with Hartford HealthCare (HHC), specializing in the care of people with Parkinson disease and other movement disorders. The Center has three locations throughout Connecticut, attending to over 3000 patients with PD and parkinsonism, and over 8900 total patients with all movement disorders. We gathered information on our patients who tested positive for COVID-19 from 8 March 2020 through 6 June 2020, spanning ninety days from the time that the first COVID-19 case was reported in Connecticut. The Center was alerted of patients who contracted COVID-19 by family members, caregivers, extended care facility staff, and physicians at other practices and regional hospitals, or when our own staff and clinicians called the patient for their follow-up telemedicine visit. We did not do a complete survey of our entire patient population. We then conducted telephone interviews and reviewed medical charts from the hospital electronic health record systems (EHRs) to obtain all pertinent data for this paper. Second, we reviewed Hartford HealthCare’s EHR to identify patients with Parkinson disease who were admitted for COVID-19 to any of our six affiliate hospitals across the state as a way to estimate the burden of COVID-19 on the population of patients with movement disorders. In each of these cases, the diagnosis of COVID-19 was established using reverse transcriptase polymerase chain reaction (rt-PCR) tests that detected nucleic acid from SARS-CoV-2 from respiratory specimen. By including patients who were identified through routine telemedicine visits, self-reporting, and inpatient registry review of the HHC EHR, we captured information on a broad spectrum of the population and minimized selection bias that can occur when conducting an exclusively community-based or inpatient hospital-based review.
