ABSTRACT
BACKGROUND:
Therapeutic doses of anticoagulation have been administered to patients with coronavirus-19 disease (Covid-19) without thromboembolism, although there is a lack of robust evidence supporting this practice. STUDY QUESTION To compare outcomes between patients admitted to the hospital for Covid-19 who received full-dose anticoagulation purely for the indication of Covid-19 and patients who received prophylactic doses of anticoagulation. STUDYDESIGN:
This is a multicenter retrospective cohort study, including 7 community hospitals in Michigan. Patients were >18 years of age, confirmed positive for Covid-19 by polymerase chain reaction, and admitted to the hospital between March 10 and May 3, 2020. Exposed group Patients receiving therapeutic dose anticoagulation for Covid-19 for any duration excluding clinically evident venous thromboembolism, atrial fibrillation, and myocardial infarction; control group Patients receiving prophylactic anticoagulation. Propensity score matching was used to adjust for the nonrandomized nature of the study. MEASURES ANDOUTCOMES:
The primary endpoint 30-day in-hospital mortality. Secondary endpoints intubation, length of hospital stay, and readmissions in survivors.RESULTS:
A total of 115 exposed and 115 control patients were analyzed. Rates of 30-day in-hospital mortality were similar (exposed 33.0% vs. control 28.7%). Controlling for institution, there was no significant association between treatment and 30-day in-hospital mortality (hazard ratio 0.63; 95% confidence interval 0.37-1.06). Survivors had statistically similar length of hospital stay and readmission rates.CONCLUSIONS:
We found no difference in mortality in patients with Covid-19 without clinically evident venous thromboembolism, atrial fibrillation, and myocardial infarction who received therapeutic versus prophylactic doses of anticoagulation.
