A dimensional approach to assessing delirium in COVID-19 in the elderly

The aim of the study was to investigate structure delirium in elderly patients with different outcomes coronavirus infection. Materials and Methods . carried out on basis Hospital for War Veterans, St. Petersburg. involved 30 patients: 13 male 17 female (median age (Med) 70.5, interquartile range (IQR) 62-83) clinical diagnosis: "New infection COVID-19 (PCR+), F05.86 other association viral bacterial neuroinfections. Peculiarities manifestations were studied using Delirium Rating Scale-Revised-98 (DRS-R-98). Current physical condition monitored National Early Warning Score (NEWS2) COVID-19. Results : All had moderate severe disorders wake-sleep cycle DRS-R-98 scale. In addition, perceptual long-term memory impairments common. A significant correlation (p<0.05) found between severity sleep-wake cycle, lability affect, formal thought disorders, motor agitation, disorientation. there correlations symptoms status scores NEWS2 lethal patients, more pronounced disturbances recorded indicators (Med.3.0, IQR 2.0-3.0 vs Med.2.0, 2.0-3.0, p=0.0327) agitation (Med.2.0, 1.0-2.5 Med.1.0, 0.0-2.0, p=0.441). logit regression model showed that variables "respiratory rate," "heart final score could be considered predictors disease outcome. Conclusion Delirium, one most frequent acute brain dysfunction, is a serious complication COID-19 hospitalized strong predictor adverse outcome older patients.
