Purpose/Background: Pharmacists have been shown to play an important role in the medication management of critically ill patients. Pharmacist interventions in the care of critically ill patients with coronavirus disease 2019 (COVID-19) have not been quantitatively described. Methodology: A single center, retrospective, observational study was conducted at Vanderbilt University Medical Center in Nashville, Tennessee. All adult patients admitted to the COVID-19 intensive care unit (ICU) or Medical ICU with a COVID-19 diagnosis between March 1, 2020, and June 30, 2021, were included. All interventions made by pharmacists were documented electronically, collected, categorized, and analyzed. The primary outcome of this study was the median number of interventions by pharmacists per patient. The secondary outcome was the number of different types of interventions performed. Results: A total of 768 patients were included in the analysis. The median age was 63 years old; 63% of patients were male and 71% were Caucasian. Median hospital length of stay (LOS) was 12 days (interquartile range (IQR) 7-21) and ICU LOS was 5 days (IQR 1-11). The median Sequential Organ Failure Assessment score was 4 (IQR 2-7) and Charlson Comorbidity Index was 3 (IQR 2-5). Mortality at 60 days occurred in 352 patients (46%). Pharmacists performed a total of 7027 interventions for 655 patients with a median number of pharmacist interventions per patient of 6 (IQR 3-14). The most common pharmacist interventions were medication discontinuation (24%), completion of components of the ICU liberation bundle (19%), medication dose adjustment (18%), therapeutic drug monitoring (15%), and medication initiation (10%). Conclusions: Pharmacists made multiple interventions related to medication use and management in critically ill patients with COVID-19. This study adds important information of the evolving role clinical pharmacists play in the care of critical illness, specifically during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]
