This study, authored by surgeons from Israel, is a review of 4 articles where elective or semi-elective surgery was performed for COVID-19 cases without testing for SARS-CoV-2. More than 50% severe disease and 27.4% mortality in such patients is of concern. All studies, however, highlighted the presence of comorbid conditions (hypertension, emphysema) and advanced age as factors more likely to lead to adverse outcomes.
