AbstractFew studies examined several anticoagulation (AC) dosage strategy therapies for various outcomes among coronavirus disease-2019 (COVID-19) patients. However, this AC dosage strategy therapy has not been investigated to assess the length of stay (LOS) and all-cause mortality among critically ill COVID-19 patients admitted to the intensive care unit (ICU), especially in the eastern province of Saudi Arabia. Thus, this study aimed to examine the association of AC dosage strategy therapy with the LOS and all-cause mortality among critically ill COVID-19 patients admitted to the ICU. We enrolled 170 patients aged 18 years or older, had a confirmed COVID-19, and were hospitalized in a tertiary care facility in the eastern province of Saudi Arabia between March 1, 2020, and January 31, 2021. Patients (n = 56) who received Enoxaparin at a dose of less than or equal to 5000 units of unfractionated heparin thrice daily were categorized as receiving a "prophylaxis" dose. Patients (n = 114) who received a therapeutic dose but not a prophylaxis dose were categorized as receiving a "therapeutic dose." The 30-day ICU LOS was the main outcome, while all-cause mortality was the secondary outcome. The covariate-adjusted logistic regression analysis revealed that the therapeutic dose was significantly associated with a 1.74-fold longer ICU LOS and 6.60-fold greater mortality risk than the prophylaxis dose. Critically ill COVID-19 patients who received the therapeutic dose had a longer ICU LOS and higher mortality than those who received the prophylaxis dose.Copyright © 2024 the Author(s).
