761: ANTIDEPRESSANT AND ANTIPSYCHOTIC PRESCRIBING FOLLOWING ICU ADMISSION DUE TO COVID-19

Abstract

Introduction: Patients with post-intensive care syndrome (PICS) suffer from a constellation of cognitive, mental, and physical effects. Previous studies have demonstrated increased antidepressant prescribing in patients with PICS. The purpose of this study was to examine the rates of antidepressant and antipsychotic use in patients with PICS following critical illness due to COVID-19. Methods: This was a retrospective chart review of adult patients (>18 years old) with PICS following critical illness due to COVID-19 who had at least 1 visit to the ICU survivor clinic at IU Health between September 2020 and July 2022. Patients were excluded if they were never admitted to the ICU, were admitted to a non IU Health ICU, or if they had incomplete medical records. The primary endpoint was the rate of combined antidepressant and antipsychotic use before ICU admission compared to their last clinic visit. The chi-square test was used to compare nominal data. Results: A total of 117 patients presented to the survivor clinic during the study time period. 35 patients were included in the analysis. Patients had a mean (+/- SD) age 53 (+/- 17) years and tended to be Caucasian 23 (66%) with low rates of having a college degree 6 (17%). During their ICU stays patients there were high rates of mechanical ventilation 24 (69%). While use of ECMO 9 (26%) and documented delirium 10 (28%) were less frequent. Underlying conditions identified at the initial clinic visit included cognitive impairment 20 (57%), depression 11 (31%), anxiety 8 (23%), and PTSD 4 (11%). Antidepressant and antipsychotic use was higher at the last clinic visit when compared to prior to ICU admission [16 (46%) vs. 5 (14%); p=0.0041]. At the time of the last clinic visit none of the 16 patients were receiving an antipsychotic while all were receiving an antidepressant. Conclusions: Patients with PICS following critical illness due to COVID-19 have an increased rate of antidepressant prescribing use compared to pre-illness. Further research is needed regarding the management and outcomes of these patients following critical illness due to COVID-19.
