- Abstract
Background: Severe COVID‐19 causes acute inflammation, which is complicated by venous thromboembolism events (VTE). However, it is unclear if VTE risk has evolved over time since the COVID‐19 outbreak. Aims: To determine markers of thrombo‐inflammation and rates of symptomatic VTE in patients hospitalised for COVID‐19 in a metropolitan hospital in Sydney, Australia. Methods: A retrospective, single‐centre, cohort study was performed by reviewing electronic medical records of consecutive patients admitted to Royal Prince Alfred Hospital between March 2020 and September 2021. This period included three waves of COVID‐19 outbreaks in Australia with the ancestral, alpha and delta variants. Standard coagulation assays and inflammatory markers were recorded over 4 weeks. Results: A total of 205 patients were consecutively admitted during the study period. Activated partial thromboplastin time, neutrophil count and C‐reactive protein (CRP) were significantly increased in patients hospitalised in the intensive care unit (ICU) compared with non‐ICU patients. The use of anti‐inflammatory medication increased in 2021 compared with 2020. The mortality rate was 7.3% in our cohort. Ninety‐four per cent of patients received anticoagulation with 6.3% of patients developing VTE. Conclusion: We observed lower rates of VTE compared to the internationally reported rate for the same period. We conclude that in the setting of controlled hospital admission rate and standard anticoagulation guidelines, COVID‐19 resulted in similar thrombo‐inflammatory response and VTE rates over the first 1.5 years of the pandemic.
