@article { , title = {Impact of COVID-19 on vascular patients worldwide: analysis of the COVIDSurg data}, abstract = {BACKGROUND: The COVIDSurg collaborative was an international multicenter prospective analysis of perioperative data from 235 hospitals in 24 countries. it found that perioperative COVID-19 infection was associated with a mortality rate of 24\%. at the same time, the COVER study demonstrated similarly high perioperative mortality rates in vascular surgical patients undergoing vascular interventions even without COVID-19, likely associated with the high burden of comorbidity associated with vascular patients. This is a vascular subgroup analysis of the COVIDSurg cohort. METHODS: All patients with a suspected or confirmed diagnosis of COVID-19 in the 7 days prior to, or in the 30 days following a vascular procedure were included. The primary outcome was 30-day mortality. Secondary outcomes were pulmonary complications (adult respiratory distress syndrome, pulmonary embolism, pneumonia and respiratory failure). logistic regression was undertaken for dichotomous outcomes. RESULTS: overall, 602 patients were included in this subgroup analysis, of which 88.4\% were emergencies. The most common operations performed were for vascular-related dialysis access procedures (20.1\%, N.=121). The combined 30-day mortality rate was 27.2\%. Composite secondary pulmonary outcomes occurred in half of the vascular patients (N.=275, 45.7\%). CONCLUSIONS: Mortality following vascular surgery in COVID positive patients was significantly higher than levels reported pre-pandemic, and similar to that seen in other specialties in the COVIDSurg cohort. initiatives and surgical pathways that ensure vascular patients are protected from exposure to COVID-19 in the peri-operative period are vital to protect against excess mortality.}, doi = {10.23736/S0021-9509.21.12024-5}, issue = {6}, journal = {Journal of Cardiovascular Surgery}, pages = {558-70}, publicationstatus = {Published}, publisher = {Edizioni Minerva Medica}, url = {https://hull-repository.worktribe.com/output/3916776}, volume = {62}, keyword = {COVID-19, Vascular surgical procedures, Health care outcome assessment}, year = {2021}, author = {Hitchman, Louise and Machin, Matthew} }
