ABSTRACT
Background: The focus on treatment of COVID-19 patients during the Sars-CoV-2 outbreak, lockdown measures and individuals' anxiety regarding potential infection when seeing a healthcare provider have likely implications on the extent of diagnosis and quality of treatment of non-COVID-19 patients. This hypothesis has been evaluated exemplarily for the early detection, diagnosis and treatment of colorectal cancer in Saxony within the framework of the CancerCOVID project. Method(s): The situation during 2020 was compared with the situation before the Sars-CoV-2 pandemic (i.e., 2019). The evaluation is based on pseudonymised routine statutory health insurance data for Saxony including more than 50% of the population. Result(s): A main finding was the drop in the number of diagnosis of new colorectal cancer cases between 2019 and 2020 (i.e., 1797 versus 1352). Furthermore, the per-patient rate of surgeries for incident colorectal cancer cases increased slightly (2.4 to 2.5), as did the rate of intravenous (IV) cytostatics administration (2.2 to 2.4) and radiation therapy (1.1 to 1.4). The per-patient rate of surgeries for prevalent colorectal cancer patients remained constant (0.3), as did the rate of radiation therapy (0.2). However, the per-patient rate of IV cytostatics for prevalent colorectal cancer patients decreased from 1.7 to 1.4. The results of analyses pertaining to cancer screenings and mortality are available as well. Discussion(s): It is likely that reduced screenings and fewer contacts with healthcare providers due to the pandemic led to the drop in new diagnosis. The reasons for the small numeric increases in the rates of procedures per incident patient versus the largely flat trajectory in the rate of health care services for prevalent cases require further exploration. Conclusion(s): COVID-19 was associated with changes in the provision of health care especially for cancer patients, which should be taken into consideration in the resource planning when preparing for another pandemic or public health emergency.
