The aim of this study is to determine the impact of the COVID-19 pandemic on the Dutch surgical care, expressed as number of performed procedures, altered treatment plans, and surgical outcomes in the Netherlands during the year 2020. This was done by executing a nationwide prospective cohort study, under the name "Dutch COVIDsurg II Snapshot Study". This study was conducted in collaboration with the Dutch Institute of Clinical Auditing (DICA). For this study, the surgical audits for lung cancer surgery (DLCA-S), Upper gastrointestinal cancer surgery (DUCA), pancreatic cancer surgery (DPCA), hepatobiliary surgery (DHBA), colorectal cancer surgery (DCRA), hip fracture surgery (DHFA), aortic aneurysm surgery (DSAA), and bariatric surgery (DATO), were expanded with an additional COVID-19 survey, since August 2020. This survey focused on alterations in, or delay of treatment and diagnostics, perioperative outcomes, and specific COVID-19 related symptoms and complications during the COVID-19 pandemic. All academic-, general community-, teaching- and non-teaching hospitals in the Netherlands performing pulmonary, upper gastrointestinal, pancreatic, hepatobiliary, colorectal, hip fracture, aneurysmal or bariatric procedures were approached to participate in the Dutch COVIDSurg II Snapshot study. Patients who underwent surgery during the period January 1st 2018 until December 31st 2019, were included in the historical cohort. Patients who underwent a surgical procedure in the period January 1st 2020 until December 31st 2020 were included in the study group.
