Summary

Observational, spontaneous, retrospective, multicenter national study for adult patients, not hospitalized, attending the Thrombo-Embolic Emergency Clinic of the Angiology and Coagulation Disorders Unit (SSD Angiologia e Malattie della Coagulazione) at the IRCCS Azienda Ospedaliero-Universitaria di Bologna, from 01/01/2018 to 31/03/2022, in whom venous thromboembolic events were suspected or confirmation was requested, as they were previously seen at another facility and referred to the reference center SSD Angiologia e Malattie della Coagulazione.

To achieve the primary objective, a case-control study will be conducted by cross-referencing data from the outpatient records of the SSD Angiologia e Malattie della Coagulazione from 29/02/2020 to 31/03/2022 with data related to SARS-CoV-2 infections provided by the Public Health Department of the Bologna Local Health Authority (Azienda USL di Bologna).

Additionally, data from the outpatient records of the SSD Angiologia e Malattie della Coagulazione from 27/12/2020 to 31/03/2022 will be integrated with data on vaccination status, date of administration, and type of vaccine administered, also provided by the Public Health Department of the Bologna Local Health Authority.

To achieve the secondary objective, data from the outpatient records of the SSD Angiologia e Malattie della Coagulazione from 01/01/2018 to 28/02/2020 will be used to describe the patient population attending the clinic during the COVID-19-free period, and will be compared with data from the period 29/02/2020 to 31/03/2022, which corresponds to the COVID-19 period.
