Quick Questions About This Study

Yes, death rates nearly tripled from 0.7% before the pandemic to 2.0% during COVID-19, despite similar pulmonary complication rates and potentially better patient selection during the pandemic period.
Mediation analysis estimated that 54.8% of excess postoperative deaths during the pandemic were directly attributable to SARS-CoV-2 infection, representing a significant portion of increased mortality.
The study included 7,402 patients from 50 countries, making it one of the largest international comparative analyses of surgical outcomes before and during the COVID-19 pandemic.
The study suggests healthcare providers likely selected patients with lower risk profiles for surgery during the pandemic, but this careful selection did not prevent the increased mortality from COVID-19.
Among patients who had surgery during the pandemic, 4.3% (187 of 4,371) developed postoperative SARS-CoV-2 infection, contributing significantly to the increased mortality rates observed.
