Characteristics, treatment and delirium incidence of older adults hospitalized with COVID-19: a multicentre retrospective cohort study.

BACKGROUND: The COVID-19 pandemic has affected older adults disproportionately, and delirium is a concerning consequence; however, the relationship between delirium and corticosteroid use is uncertain. The objective of the present study was to describe patient characteristics, treatments and outcomes among older adults hospitalized with COVID-19, with a focus on dexamethasone use and delirium incidence. METHODS: We completed this retrospective cohort study at 7 sites (including acute care, rehabilitation and long-term care settings) in Toronto, Ontario, Canada. We included adults aged 65 years or older, consecutively hospitalized with confirmed SARS-CoV-2 infection, between Mar. 11, 2020, and Apr. 30, 2021. We abstracted patient characteristics and outcomes from charts and analyzed them descriptively. We used a logistic regression model to determine the association between dexamethasone use and delirium incidence. RESULTS: During the study period, 927 patients were admitted to the acute care hospitals with COVID-19. Patients' median age was 79.0 years (interquartile range [IQR] 72.0-87.0), and 417 (45.0%) were female. Most patients were frail (61.9%), based on a Clinical Frailty Scale score of 5 or greater. The prevalence of delirium was 53.6%, and the incidence was 33.1%. Use of restraints was documented in 20.4% of patients. In rehabilitation and long-term care settings (n = 115), patients' median age was 86.0 years (IQR 78.5-91.0), 72 (62.6%) were female and delirium occurred in 17 patients (14.8%). In patients admitted to acute care during wave 2 of the pandemic (Aug. 1, 2020, to Feb. 20, 2021), dexamethasone use had a nonsignificant association with delirium incidence (adjusted odds ratio 1.38, 95% confidence interval 0.77-2.50). Overall, in-hospital death occurred in 262 (28.4%) patients in acute care settings and 28 (24.3%) patients in rehabilitation or long-term care settings. INTERPRETATION: In-hospital death, delirium and use of restraints were common in older adults admitted to hospital with COVID-19. Further research should be directed to improving the quality of care for this population with known vulnerabilities during continued waves of the COVID-19 pandemic.

Use of the Consultation Letter Rating Scale among Geriatric Medicine Postgraduate Trainees.

OBJECTIVES: The implementation of competency-based evaluations increases the emphasis on in-training assessment. The Consultation Letter Rating Scale (CLRS), published by the Royal College of Physicians and Surgeons of Canada, is a tool that assesses written-communication competencies. This multisite project evaluated the tool's validity, reliability, feasibility, and acceptability for use in postgraduate geriatric medicine training. METHODS: Geriatric medicine trainees provided consultation letters from the 2017-2018 academic year. Geriatricians reviewed a standardized module and completed the tool for all the deidentified letters. The reviewers recorded the time used to complete the tool for each letter and completed a survey on content validity. Trainees completed a survey on the tool's usefulness. Responses were reviewed independently by two authors for thematic content. The unweighted and the weighted κ were used to measure interrater reliability. RESULTS: A total of 10 of 11 (91%) eligible trainees each provided five letters that were reviewed independently by six geriatricians, leading to a total of 300 assessments. A very small portion (4% [N = 12]) of assessments was incomplete. An average of 4.82 minutes (standard deviation = 3.17) was used to complete the tool. There was high interrater agreement for overall scores, with a multiple-rater weighted κ of 83% (95% confidence interval = 76%-89%). The interrater agreement was lower for the individual components. Both raters and trainees found the comments more useful than the numerical ratings. CONCLUSIONS: Our results support the use of the CLRS for facilitating feedback on the quality of consult letters to improve written-communication competencies among geriatric medicine trainees.
