Mental Disorders Among Hospitalized Patients With Covid-19 In Moscow, Russia: A Prospective Cohort Study

Abstract

We assessed the prevalence of mental disorders in hospitalized patients with the coronavirus disease 2019 (COVID-19) in the Coronavirus Infection Treatment Units nos. 1-4 at Sechenov University (Moscow, Russia). In the first group (n=440), all patients were observed by trained psychiatrists using the Mini-Mental State Examination, Delirium Rating Scale-R-98, Patient Health Questionnaire, General Anxiety Disorder-7, and the Insomnia Severity Index. In the second group (n=455), only patients with identified signs of mental disorders were examined. In total, 237 (53.9%) and 110 (24.2%) patients in the first and second groups showed signs of mental illness, respectively: delirium, 122 (27.8%) and 81 (17.8%); anxiety, 108 (24.5%) and 22 (4.8%); depression, 54 (12.3%) and 6 (1.3%); mild cognitive impairment, 78 (17.8%) and 13 (2, 9%); dementia, 68 (15.5%), and 39 (8.6%) patients, respectively. The prevalence of mental illness among hospitalized patients with COVID-19 is significantly higher than that detected by non-psychiatric clinicians.
