Background: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV2)-related pneumonia is associated with venous and arterial thrombosis . Aim of the study was to find-out a new score for predicting thrombosis in patients with SARS-CoV-2. Methods: We included a cohort of 674 patients affected by SARS-CoV-2, not requiring intensive care units, and followed-up during the hospitalization until discharge. Routinary analyses performed at in-hospital admission included also serum albumin and D-dimer while arterial and venous thromboses were the end-points of the study. Results: During the follow-up thrombotic events 110 were registered; patients with thrombotic events were older and had lower albumin and higher D-dimer, compared to thrombotic event-free ones. On multivariable logistic regression with step by stepwise procedure age, serum albumin, D-dimer, were independently associated with thrombotic events. The linear combination of age, D-dimer, albumin allowed to build-up the ADA score, whose AUC was 0.752 (95% CI, 0.708-0.795). ADA score was internally validated by bootstrap sampling procedure giving an AUC of 0.752 (95% CI: 0.708 - 0.794). Conclusions: Combination of age, D-dimer, albumin in the ADA score allows identifying SARS-CoV-2 patients at higher risk of thrombotic events.
