Abstract Background Beneficial effects of centralization could be shown. During SARS-CoV2 pandemic however, the centralization in the UK healthcare system led to cessation of screening colonoscopies and oncological resections. In the decentralized healthcare system of Switzerland, a high frequency of colonoscopies could be maintained. Aims The aim of this international study is to evaluate if a decentralized health care systems can prevent the threatening unmet needs of colorectal cancer patients under pandemic conditions. Methods This observational trial was performed in the south-east of Scotland and in the extended northwest of Switzerland with a catchment area of 1.5 Mio. inhabitants each. Patients with colorectal cancer diagnosed during January 2019 and December 2022 were included. Results Six thousand six hundred and eighty patients were included in this preliminary analysis (4059 in the NHS group and 2621 in the Swiss group). In Scotland the median number of diagnosed patients per quarter was 258 pre-pandemics, 218 during lockdown and 258 after lockdown (p=0.56). There was no significant alteration of the median diagnosed patients per quarter during different phases in Switzerland (165 pre-pandemic vs. 187 during lockdown vs. 162 post-lockdown, p=0.56). In Scotland the median number of all performed tumor treatments per quarter were lower during lockdown (83 pre-pandemic vs. 75 during lockdown vs. 93 post-lockdown, p0.01). In Switzerland the median treatment numbers per quarter didn´t differ during different phases (56 pre-pandemic vs. 62 during lockdown vs. 60 post-lockdown, p=0.51). The number of patients diagnosed with a T4 tumor during pandemic was higher in Scotland than in Switzerland (28% vs. 19%, p0.01). The 30-day mortality under pandemic condition was 7.5% (65 of 859) in Scotland compared to 3.7% (14 of 374) in Switzerland (p=0.01). Conclusion SARS-CoV2 pandemic led to a reduction in performed cancer treatments in Scotland. In Switzerland's decentralized healthcare system, cancer treatments were maintained during pandemic.
