MONDAY, March 20, 2023 (HealthDay News) — The absolute risk for venous thromboembolism (VTE) is low among outpatients with COVID-19, according to a study published online March 13 in JAMA Network Open<\/em>.<\/p>\n Margaret C. Fang, M.D., from the University of California in San Francisco, and colleagues assessed the risk for VTE among outpatients with COVID-19. The analysis included data from 398,530 outpatients identified from the Kaiser Permanente Virtual Data Warehouse and electronic health records (Jan. 1, 2020, to Jan. 31, 2021).<\/p>\n The researchers found that 0.1 percent of patients had a VTE event during the study period. The sharpest increase in VTE risk occurred during the first 30 days after COVID-19 diagnosis (unadjusted rate, 0.58 versus 0.09 after 30 days). Risk factors for VTE among COVID-19 outpatients included age 55 to 64 years (hazard ratio [HR], 1.85), 65 to 74 years (HR, 3.43), 75 to 84 years (HR, 5.46), and 85 years and older (HR, 6.51); male gender (HR, 1.49); prior VTE (HR, 7.49); thrombophilia (HR, 2.52); inflammatory bowel disease (HR, 2.43); body mass index of 30.0 to 39.9 kg\/m\u00c2\u00b2 (HR, 1.57); and body mass index \u00e2\u0089\u00a540.0 kg\/m\u00c2\u00b2 (HR, 3.07).<\/p>\n “These findings may help identify subsets of patients with COVID-19 who may benefit from more intensive surveillance or VTE preventive strategies,” the authors write.<\/p>\n
